Please refer to FIGS. 1-2 together. The electronic device 100 according to the embodiment of the present application includes a housing 10, a touch display screen 20, and a proximity sensor 30.

Referring to FIG. 3, the housing 10 includes a base plate 12 and a surrounding wall 14 extending rearwardly from an edge of the base plate 12. The base plate 12 and the surrounding wall 14 together form a receiving space 16. The surrounding wall 14 has a light passage hole 142 that communicates with the accommodation space 16. The touch display screen 20 is disposed on the front side of the substrate 12. The proximity sensor 30 is provided in the accommodation space 16. The proximity sensor 30 includes an infrared transmitter 33 and an infrared receiver 34. The infrared emitter 33 is used to emit infrared light to the front side of the substrate 12 through the light through hole 142. The infrared receiver 34 is configured to receive infrared light emitted by the infrared transmitter 33 and reflected back by an external object.

In the electronic device 100 according to the embodiment of the present application, the proximity sensor 30 emits infrared light to the front side of the substrate 12 through the light through hole 142 located in the surrounding wall 14 and receives infrared light reflected by the object. The electronic device 100 may control a display state of the touch display screen 20 according to a signal of the proximity sensor 30. The proximity sensor 30 is covered by the touch display screen 20, which does not occupy the front space of the substrate 12, avoids interference between the proximity sensor 30 and the touch display screen 20, and increases the screen ratio of the electronic device 100.

Exemplarily, the electronic device 100 may be any of various types of computer system equipment that is mobile or portable and performs wireless communication (only one form is shown by way of example in FIG. 1). Specifically, the electronic device 100 may be a mobile phone or a smart phone (e.g., iPhoneTM, AndroidTM-based phone), a portable gaming device (e.g. Nintendo DSTM, PlayStation PortableTM, Gameboy AdvanceTMTM, iPhoneTM), a laptop Computers, PDAs, portable Internet devices, music players, and data storage devices, other handheld devices, such as watches, in-ear headphones, pendants, headphones, etc. The electronic device 100 may also be other wearable devices (for example, Such as electronic glasses, electronic clothes, electronic bracelets, electronic necklaces, electronic tattoos, electronic devices, or head-mounted devices (HMDs) for smart watches.

The electronic device 100 may also be any one of a plurality of electronic devices, including, but not limited to, a cellular phone, a smart phone, other wireless communication devices, a personal digital assistant, an audio player, other media players, and a music recorder. , Video recorder, camera, other media recorder, radio, medical equipment, vehicle transportation equipment, calculator, programmable remote control, pager, laptop computer, desktop computer, printer, netbook computer, personal digital assistant (PDA), portable Multimedia player (PMP), Moving Picture Experts Group (MPEG-1 or MPEG-2) audio layer 3 (MP3) player, portable medical equipment, and digital camera and combinations thereof.

In some cases, the electronic device 100 may perform multiple functions (eg, play music, display video, store pictures, and receive and send phone calls). If desired, the electronic device 1000 may be a portable device such as a cellular phone, media player, other handheld device, wristwatch device, pendant device, handset device, or other compact portable device.

The casing 10 has a substantially rectangular parallelepiped shape. The casing 10 is a carrier of the electronic device 100 and is used to carry most parts of the electronic device 100. The casing 10 may be made of plastic or metal material, or a plastic and metal may be formed into an integrated structure through an in-mold injection molding process. In one embodiment, the material of the substrate 12 is metal, and the material of the surrounding wall 14 is plastic.

The manufacturing method of the casing 12 includes: firstly putting the substrate 12 into a mold, and then injecting molten plastic into the mold, and forming the surrounding wall 14 after the plastic is cured, thereby obtaining the casing 10.

The touch display screen 20 may include a display screen 21 and a cover plate 22 that covers the display screen 21. The display screen 21 is, for example, a flexible display such as an OLED (Organic Light-Emitting Diode). Of course, the display screen 21 may also be a liquid crystal display. The cover 22 covers the display screen 21 to reduce the impact of the display screen from the outside. The touch display screen 20 may be fixed on the front side of the substrate 12 by an adhesive.

The touch display screen 20 can receive external touch input, thereby generating corresponding signals, so that the touch display screen 20 can run in different states. For example, when the touch display screen 20 is playing video content, if the touch display screen 20 receives a click input, the touch display screen 20 may pause the video playback.

After the infrared emitter 33 emits infrared light to the front side of the substrate 12, if the infrared light reaches the object 200 on the front side of the substrate 12, the infrared light will be reflected by the object 200, and the reflected infrared light will be transmitted from the light hole 142 to the infrared The receiver 34 and the infrared receiver 34 generate corresponding electric signals according to the acquired infrared light. The electronic device 100 can thus calculate the distance between the proximity sensor 30 and the object 200 according to the time difference between the infrared light emitted by the infrared transmitter 33 and the received infrared light, and then control the display state of the touch display screen 20 according to the time difference.

For example, when an object 200 approaches the touch display screen 20, the touch display screen 20 may be controlled to be in an off state. The “screen off state” referred to here means that the touch display screen 20 is powered off and cannot display content.

As shown in FIG. 1, the electronic device 100 includes a processor 40 configured to control a display state of the touch display screen 20 according to infrared light received by the infrared receiver 30. In one example, when the user answers or makes a call and places the electronic device 100 near the head, the processor 40 calculates the time when the proximity sensor 30 emits infrared light and receives the infrared light reflected by the object 200 to generate detection information. The processor 40 turns off the touch display screen 20 according to the detection information. When the electronic device 100 is far away from the head, the processor 40 turns on the touch display screen 20 again according to the detection information fed back by the proximity sensor 30.

In this embodiment, the proximity sensor 30 may be fixed on the substrate 12 through a component such as a bracket, or the proximity sensor 30 may be fixed on other components of the electronic device 100.

The light passage hole 142 is, for example, a straight hole, or the inner surface of the light passage hole 142 is linear in the axial direction of the light passage hole 142. Of course, in the axial direction of the light-passing hole 142, the inner surface of the light-passing hole 142 may also be a curve type or a polygonal line type. The infrared light emitted by the proximity sensor 30 can be emitted to the front side of the touch display screen 20 through the light through hole 142.

It should be noted that the infrared light reflected by the object passes through the light-passing hole 142 and is received by the infrared receiver 34.

Referring to FIG. 3, in one example, the axis 1422 of the light through hole 142 may be vertically arranged. It should be noted that although the axis 1422 of the through-hole 142 is vertically arranged, because the infrared light emitted by the infrared emitter 33 is inclined, the infrared light emitted by the infrared emitter 33 can also be transmitted to the front side of the touch display screen 20 In order to detect whether there is an object covering the touch display screen 20 on the front side of the touch display screen 20.

Of course, in another example, in a direction in which the side of the light-through hole 142 near the proximity sensor 30 is away from the side of the proximity sensor 30, the axis 1422 of the light-through hole 142 is inclined toward the front side of the substrate 12, as shown in FIG. 4 shown. In this way, the infrared light emitted by the infrared emitter 33 is more easily transmitted to the front side of the touch display screen 20 after passing through the light through hole 142.

In the present embodiment, the light through hole 142 is located at the top position of the surrounding wall 14. That is, the light through hole 142 is located on the top of the electronic device 100. The “top” referred to here is: when the electronic device 100 is in an upright normal use state, the electronic device 100 is located at an end far from the ground. In other words, the “top” is an end portion of one side of the electronic device 100 in the longitudinal direction. Of course, the light through hole 142 may also be located at other positions of the surrounding wall 14, for example, the light through hole 142 is located at the bottom or side of the surrounding wall 14.

It should be noted that, in this embodiment, the “front side” is that the infrared light generated by the touch display screen 20 is emitted to a side outside the electronic device 100. For example, when the user watches the content displayed on the touch display screen 20, the side of the touch display screen 20 facing the user is the front side. Conversely, the side opposite to the front side is the rear side.

It should be noted that the infrared light emitted by the infrared emitter 33 does not pass through the substrate 12 and thus does not pass through the touch display screen 20. The infrared light emitted by the infrared emitter 33 forms an acute angle with the thickness direction (horizontal direction in FIG. 3) of the touch display screen 20, so that the infrared light can be emitted to the front side of the substrate 12. The proximity sensor 30 is disposed in the accommodation space 16, that is, the proximity sensor 30 is disposed in the housing 10.

Referring to FIG. 3, in some embodiments, the emission optical axis 31 of the infrared emitter 33 passes through the light through hole 142, and the emission optical axis 31 of the infrared emitter 33 is inclined from the infrared emitter 33 to the front side of the substrate 12.

The emission optical axis 31 of the infrared emitter 33 is inclined toward the front side of the substrate 12, so that the included angle between the infrared light emitted by the infrared emitter 33 and the horizontal direction is smaller, so that the infrared light emitted by the infrared emitter 33 can be transmitted to The object 200 in front of the display screen 20 is touched to detect whether an object 200 approaches the touch display screen 20.

It can be understood that the infrared light emitted by the infrared emitter 33 has a certain emission angle. The emission angle of the infrared emitter 33 is an included angle between the infrared light emitted by the infrared emitter 33 and the emission optical axis 31. The emission optical axis 31 of the infrared emitter 33 passes through the middle portion of the second aperture 1426, so that the infrared light emitted by the infrared emitter 33 can be emitted from the edge position of the second aperture 1426 to the front side of the substrate 12.

The emission optical axis 31 of the infrared emitter 33 coincides with the central axis of the infrared light emitted by the infrared emitter 33. The infrared light emitted by the proximity sensor 30 is distributed around the emission optical axis 31 of the infrared emitter 33.

Specifically, the light-passing hole 142 includes a first aperture 1424 and a second aperture 1426. The first aperture 1424 is close to the proximity sensor 30. The second aperture 1426 is remote from the proximity sensor 30. The emission optical axis 31 of the infrared emitter 33 passes through a middle position of the second aperture 1426.

Referring to FIG. 3, in some embodiments, an included angle a between the emission optical axis 31 of the infrared emitter 33 and the horizontal direction is 30-60 degrees. For example, the included angle a is an angle such as 30 degrees, 35 degrees, 40 degrees, 50 degrees, and 60 degrees. When the included angle a is in the above angle range, more infrared light emitted by the infrared emitter 33 can be emitted from the through hole 142 to the front side of the touch display screen 20 to detect whether an object 200 covers the touch display screen 20.

It can be understood that the infrared light emitted by the infrared emitter 33 has a certain emission angle. Therefore, with the emission optical axis 31 of the infrared emitter 33 as a boundary, the included angle between the infrared light near the front side of the substrate 12 and the horizontal direction is smaller than the included angle a, and the included angle between the infrared light far from the front side of the substrate 12 and the horizontal direction. Greater than the angle a. For example, when the included angle a is 45 degrees, the included angle between the infrared light near the front side of the substrate 12 and the horizontal direction is 35 degrees, and the included angle between the infrared light near the front side of the substrate 12 and the horizontal direction is 60 degrees.

It should be noted that the horizontal direction referred to in this application is the thickness direction of the touch display screen 20, that is, the angle a between the emission optical axis 31 of the infrared emitter 33 and the thickness direction of the touch display screen 20 is 30- 60 degrees.

Please refer to FIG. 3, FIG. 7 and FIG. 8 together. In some embodiments, the proximity sensor 30 further includes a circuit board 32, and the circuit board 32 is disposed horizontally. Both the infrared transmitter 33 and the infrared receiver 34 are provided on the circuit board 32. The emission optical axis 31 of the infrared emitter 33 is inclined with respect to the circuit board 32 so that the emission optical axis 31 of the infrared emitter 33 is inclined toward the front side of the substrate 12.

The circuit board 32 is set horizontally, and the emission optical axis 31 of the infrared emitter 33 is inclined with respect to the circuit board 32, so that the emission optical axis 31 of the infrared emitter 33 is inclined with respect to the horizontal direction, so that the emission of the infrared emitter 33 After the optical axis 31 passes through the light through hole 142, it can be tilted toward the front side of the substrate 12, so that the infrared light emitted by the infrared emitter 33 can be incident on the front side of the touch display screen 20.

The inclined setting of the emission optical axis 31 of the infrared transmitter 33 with respect to the circuit board 32 means that: the emission optical axis 31 of the infrared transmitter 33 is not perpendicular to the circuit board 32, and the emission optical axis 31 of the infrared transmitter 33 is relative to the circuit board The angle b between the surfaces of 32 is an acute angle.

In other words, the angle b between the emission optical axis 31 of the infrared emitter 33 and the circuit board 32 is less than 90 degrees. In one example, the included angle b between the emission optical axis 31 of the infrared emitter 33 and the circuit board 32 is 30-60 degrees. For example, the included angle b is an angle such as 30 degrees, 35 degrees, 45 degrees, 50 degrees, or 60 degrees. It can be understood that when the circuit board 32 is disposed horizontally, the included angle a and the included angle b are the same.

Specifically, the circuit board 32 is, for example, a printed circuit board (PCB). The horizontal setting of the circuit board 32 means that the upper surface of the circuit board 32 is horizontal, or the thickness direction of the circuit board 32 is vertical. status.

Referring to FIG. 5, in some embodiments, the circuit board 32 of the proximity sensor 30 is disposed obliquely with respect to the horizontal direction. Both the infrared transmitter 33 and the infrared receiver 34 are provided on the circuit board 32. The infrared transmitter 33 is used to emit infrared light, the infrared receiver 34 is used to receive infrared light, and the emission optical axis 31 of the infrared transmitter 33 is vertically disposed with respect to the circuit board 32 so that the emission optical axis 31 of the infrared transmitter 33 is directed to the substrate The front side of 12 is inclined.

The circuit board 32 is disposed obliquely with respect to the horizontal direction, and the emission optical axis 31 of the infrared emitter 33 is disposed perpendicularly with respect to the circuit board 32, so that the emission optical axis 31 of the infrared emitter 33 is disposed obliquely with respect to the horizontal direction, so that infrared emission After the transmitting optical axis 31 of the transmitter 33 passes through the light-through hole 142, it can be tilted toward the front side of the substrate 12, so that the infrared light emitted by the infrared transmitter 33 can be incident on the front side of the touch display screen 20.

It can be understood that although the emission optical axis 31 of the infrared emitter 33 is perpendicular to the circuit board 32, since the infrared light emitted by the infrared emitter 33 has a certain emission angle, the infrared light emitted by the infrared emitter 33 can be relative to the circuit The plate 32 is inclined.

Please refer to FIGS. 5 and 9. In an example, the angle c of the circuit board 32 inclined with respect to the horizontal direction is 30-60 degrees. For example, the angle c is an angle such as 30 degrees, 35 degrees, 45 degrees, 50 degrees, or 60 degrees.

Please refer to FIGS. 10-12 together. In some embodiments, the infrared emitter 33 includes a light emitting source 331 and a light transmitting element 332. The light emission source 331 is provided on the circuit board 32. The light transmitting element 332 covers a light emitting source 331. The light transmitting element 332 includes a front light transmitting portion 3321 and a rear light transmitting portion 3322 connected to the front light transmitting portion 3321. The front light transmitting portion 3321 is located on the front side of the emission optical axis 31 of the light emission source 331. The rear light transmitting portion 3322 is located on the rear side of the emission optical axis 31 of the light emission source 331. The infrared receiver 34 is located on one side of the light emission source 331. The proximity sensor 30 further includes a light shielding element 35 that covers at least a part of the rear light transmitting portion 3322.

In this way, the light shielding element 35 blocks at least a part of the rear light transmitting portion 3322, so that the infrared light emitted from the front light transmitting portion 3321 can be more concentrated, the energy of the infrared light emitted from the front light transmitting portion 3321 is increased, and the infrared light exit distance is further It is also beneficial for the infrared light to hit the object 200 and be reflected back to the infrared receiver 34, which improves the detection capability of the proximity sensor 30.

Specifically, the light transmitting element 332 may be made of a light transmitting material. For example, the material of the light transmitting element 332 is resin or glass. The light-transmitting element 332 covers a light-emitting source 331, or in other words, the light-emitting source 331 is disposed in the light-transmitting element 332. In this way, the light transmitting element 332 can protect the light emitting source 331 and avoid problems such as damage to the light emitting source 331 due to contact with oxygen.

It should be noted that the “front side” referred to in the front side of the emission optical axis 31 coincides with the direction of the “front side” referred to in the front side of the substrate 12 described above. Therefore, the infrared light emitted by the light emitting source 331 can reach the front side of the touch display screen 20 after passing through the front light emitting part and the light passing hole 142 in order to detect whether the touch display screen 20 is blocked.

It should be noted that the light shielding element 35 extends from the left side to the right side of the rear light transmitting portion 3322. That is, both the left rear portion and the right rear portion of the rear light transmitting portion 3322 are covered. The light-shielding element 35 is, for example, an element that blocks infrared light, such as foam, a black ink layer, or a metal layer.

When the proximity sensor 30 is provided with the light shielding element 35, the emission optical axis 31 of the infrared emitter 33 may be perpendicular to the circuit board 32 or may be disposed obliquely to the circuit board 32. The circuit board 32 may be disposed obliquely with respect to the horizontal direction, or may be disposed horizontally.

With reference to FIG. 6, in some embodiments, the front light transmitting portion 3321 is disposed near the touch display screen 20. The rear light transmitting portion 3322 is disposed away from the touch display screen 20. The light emission source 331 is used to emit infrared light to the front side of the substrate 12 through the front light transmitting portion 3321 and the light transmission hole 142.

In this way, the proximity sensor 30 can work normally to detect whether an object 200 is blocked by the front side of the touch display screen 20.

As shown in the example of FIG. 6, the emission optical axis 31 of the infrared emitter 33 is perpendicular to the circuit board 32, and the circuit board 32 is disposed horizontally. At this time, the infrared light emitted by the infrared emitter 33 is emitted from the front light transmitting portion 3321 of the light transmitting element 332, and passes through the light through hole 142 to the front side of the touch display screen 20.

Please refer to FIG. 12. In some embodiments, the light shielding element 35 covers the entire rear light transmitting portion 3322. In other words, the light shielding element 35 completely covers the rear transparent portion 3322. At this time, the infrared light emitted by the light emitting source 331 is emitted from the front transparent portion 3321, so that the energy of the emitted light is more concentrated.

Further, the emission optical axis 31 of the light emission source 331 is perpendicular to the circuit board 32. The light-shielding element 35 covers a portion of the front light-transmitting portion 3321 near the emission optical axis 31 of the light emission source 331. That is, a part of the front light transmitting portion 3321 near the emission optical axis 31 is shielded by the light shielding element 35, and infrared light emitted from the light emission source 331 is emitted from a portion far from the emission optical axis 31.

At this time, the optical axis of the light emission source 331 passes through the light shielding element 35. The light emitting source 331 emits infrared light obliquely from the front light transmitting portion 3321 and out of the light transmitting element 332, passes through the light through hole 142 and passes to the front side of the substrate 12 to detect whether the object 200 covers the touch display screen 20.

Of course, in some embodiments, the light shielding element 35 covers a part of the rear light transmitting portion 3322.

Referring to FIG. 12, in some embodiments, an included angle d between the infrared light emitted from the front light transmitting portion 3321 and the emission optical axis 31 of the light emission source 331 is 30-60 degrees. In other words, at this time, the emission angle of the infrared emitter 33 is 30-60 degrees. For example, the angle of the included angle d is a specific angle such as 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, or 60 degrees.

When the circuit board 32 is set horizontally, the included angle between the infrared light emitted by the light emitting source 331 and the horizontal direction is also 30-60 degrees, so that the infrared light emitted by the light emitting source 331 can be set on the front side of the touch display screen 20.

Please refer to FIG. 7 and FIG. 10 to FIG. 11 together. In some embodiments, the proximity sensor 30 includes a cover 36, and the cover 36 is configured with an infrared transmitter 33 and an infrared receiver 34. The cover body 36 includes a top plate 361 and a side plate 362 extending from an edge of the top plate 361. The side plate 362 surrounds the infrared transmitter 33 and the infrared receiver 34. The top plate 361 has a through hole 3611 through which the infrared transmitter 33 and the infrared receiver 34 are exposed.

In this way, the cover 36 can protect the infrared transmitter 33 and the infrared receiver 34, thereby improving the life of the proximity sensor 30. The cover body 36 may be supported by a material having a relatively high rigidity. For example, the material of the cover body 36 is metal, and specifically, the material of the cover body 36 is stainless steel, for example. The cover body 36 can be formed into a top plate 361 and a side plate 362 by a stamping process, thereby forming the cover body 36.

Please refer to FIG. 7 and FIG. 10 to FIG. 11 together. In some embodiments, the cover 36 further includes a light blocking plate 363. The light blocking plate 363 is connected to the top plate 361 and isolates the infrared transmitter 33 and the infrared receiver 34. In this way, the light blocking plate 363 can prevent the infrared light emitted by the infrared transmitter 33 from directly transmitting to the infrared receiver 34 and affect the normal operation of the infrared receiver 34.

It can be understood that if the infrared light emitted by the infrared transmitter 33 is directly transmitted to the infrared receiver 34, at this time, the infrared receiver 34 generates a signal representing that the front side of the touch display screen 20 is blocked, so that the processor 40 incorrectly controls the touch Display status of the display screen 20.

The material of the light blocking plate 363 is a light shielding material, and the light blocking plate 363 may be integrated with the top plate 361. In other words, the top plate 361, the light blocking plate 363, and the side plate 362 may be formed by a stamping and bending process.

Please refer to FIG. 7 and FIG. 10-FIG. 11 together. In some embodiments, the circuit board 32 is formed with a groove 321, and an end of the light blocking plate 363 away from the top plate 361 is inserted into the groove 321. In this way, the groove 321 can not only position the cover body 36 through the light blocking plate 363, but also make the cover body 36 mounted on the circuit board 32 more stable, which is beneficial to improving the stability of the proximity sensor 30. Specifically, the groove 321 is in a strip shape, and the groove 321 cooperates with the light blocking plate 363. The size of the groove 321 is slightly larger than the size of the light blocking plate 363 so that the light blocking plate 363 can be inserted into the groove 321.

Please refer to FIG. 2 and FIG. 3 again. In some embodiments, the electronic device 100 includes a light guide pillar 50 filled in the light through hole 142. In this way, the light guide pillar 50 is advantageous for exporting infrared light to the front side of the substrate 12, and also can reduce foreign matter such as dust, liquid and the like from entering the electronic device 100 and damage the electronic device 100. It can be understood that the light guide post 50 is made of a light-transmitting material. For example, the material of the light guide post 50 is a material such as silica gel or resin.

The light guide pillar 50 and the casing 10 may be a separate molded structure. For example, after the housing 10 and the light guide post 50 are separately formed, the light guide post 50 is inserted into the light passing hole 142. At this time, a slight gap is formed between the light passing hole 142 and the light guide post 50. Of course, the light guide post 50 and the housing 10 may be an integrally formed structure. For example, after the light-passing hole 142 is formed in the surrounding wall 14, a molten light-guiding material is injected into the light-passing hole 142. 14 is combined into an integrated light guide post 50, and the light guide post 50 and the surrounding wall 14 are difficult to separate.

Referring to FIG. 6, in some embodiments, the surrounding wall 14 includes an outer side surface 144, and the light guide pillar 50 includes a top surface 52 facing the outer side of the housing 10. The top surface 52 and the outer side surface 144 smoothly transition and abut. This can improve the aesthetics of the electronic device 100. The smooth transition butt refers to that the height difference formed at the abutment between the top surface 52 and the outer side surface 144 is very small, or the height difference is zero.

Please refer to FIG. 3 again. In some embodiments, the light through hole 142 includes a first aperture 1424 and a second aperture 1426. The first aperture 1424 is close to the proximity sensor 30, and the second aperture 1426 is far away from the proximity sensor 30. The electronic device 100 further includes a light transmitting body 60 that covers and seals the first aperture 1424.

In this way, the transparent body 60 not only allows infrared light emitted by the infrared emitter 33 to pass into the light-passing hole 142, but also prevents foreign objects from the outside from entering the electronic device 100 and damaging the electronic device 100.

In one example, the light-transmitting body 60 is in the shape of a sheet, and the light-transmitting body 60 may be on the inner side of the surrounding wall 14 by an adhesive. Since the adhesive has a sealing effect, this allows the light transmitting body 60 to seal the second aperture 1426.

Please refer to FIG. 2 again. In some embodiments, the light transmissive body 60 and the light guide post 50 are integrally formed. For example, the materials of the translucent body 60 and the light guide post 50 are both resins. In this way, the integrated translucent body 60 and the light guide post 50 can be formed by in-mold casting. In one example, the assembling process of the light guide post 50 includes: the light guide post 50 extends from the housing 10 into the light through hole 142, so that the light transmitting body 60 abuts against the inner side of the surrounding wall 14.

Please refer to FIG. 2 and FIG. 3. In some embodiments, the electronic device 100 further includes an electro-acoustic element 70. The electro-acoustic element 70 is disposed adjacent to the proximity sensor 30. The substrate 12 has a sound path 122 through which the power-supplying acoustic element 70 emits sound toward the front side of the substrate 12.

The electro-acoustic element 70 is, for example, a receiver. The electro-acoustic element 70 emits a sound when the electronic device 100 is in a call service. In this way, when the electronic device 100 is in a call service, if the user brings the electro-acoustic element 70 close to the ear, the proximity sensor 30 can detect that the object 200 covers the touch display screen 20, and the processor 40 controls the touch display screen 20 to be in the off state. .

In summary, the electronic device 100 according to the embodiment of the present application includes a casing 10, a touch display screen 20, and a proximity sensor 30. The housing 10 includes a base plate 12 and a side wall 14 extending rearwardly from an edge of the base plate 12. The base plate 12 and the side wall 14 together form a receiving space 16, and the side wall 14 is provided with a light through hole 142 communicating with the receiving space 16. The touch display screen 20 is disposed on the front side of the substrate 12.

The proximity sensor 30 is disposed in the accommodation space 16. The proximity sensor 30 includes a proximity sensor 30 including a circuit board 32, a transmitter 33, and a receiver 34. The circuit board 32 is disposed obliquely with respect to the horizontal direction. Both the transmitter 33 and the receiver 34 are provided on the circuit board 32. The transmitter 33 is used to emit light toward the front side of the substrate 12 through the light-through hole 142, and the receiver 34 is used to receive light from the front side of the substrate 12.

In the electronic device 100 according to the embodiment of the present application, the circuit board 32 is disposed obliquely so that the transmitter 33 emits light toward the front side of the substrate 12 through the light through hole 142 located on the side wall 14, and the receiver 34 receives the light from the front side of the substrate 12. The light allows the electronic device 100 to control the operation of the touch display screen 20 according to the signal of the proximity sensor 30, and the proximity sensor 30 does not occupy the front space of the substrate 12, avoiding interference between the proximity sensor 30 and the touch display screen 20, improving the electronic device 100 Screen ratio.

In some embodiments, the included angle c between the circuit board 32 and the horizontal direction is 30-60 degrees. For example, the angle c is an angle such as 30 degrees, 35 degrees, 45 degrees, 50 degrees, or 60 degrees.
