Referring to fig. 1-2 together, an electronic device 100 according to an embodiment of the present disclosure includes a housing 10, a touch display 20, and a proximity sensor 30.

Referring to fig. 3, the housing 10 includes a substrate 12 and a peripheral wall 14 extending rearward from an edge of the substrate 12. The substrate 12 and the walls 14 together define a receiving space 16. The wall 14 has a light-passing hole 142 communicating with the receiving space 16. The touch display screen 20 is provided on the front side of the substrate 12. The proximity sensor 30 is disposed in the housing space 16. The proximity sensor 30 includes an infrared transmitter 33 and an infrared receiver 34. The infrared emitter 33 is for emitting infrared light to the front side of the substrate 12 through the light passing hole 142. The infrared receiver 34 is used for receiving the infrared light emitted by the infrared emitter 33 and reflected back by the external object.

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

By way of example, the electronic device 100 may be any of various types of computer system equipment (only one modality shown in FIG. 1 by way of example) that is mobile or portable and that performs wireless communications. Specifically, the electronic apparatus 100 may be a mobile phone or a smart phone (e.g., an iPhone (TM) based phone), a Portable game device (e.g., Nintendo DS (TM), PlayStation Portable (TM), game Advance (TM), iPhone (TM)), a laptop computer, a PDA, a Portable internet appliance, a music player and a data storage device, other handheld devices and a headset such as a watch, an in-ear headphone, a pendant, a headset, etc., and the electronic apparatus 100 may also be other wearable devices (e.g., a Headset (HMD) such as electronic glasses, electronic clothing, an electronic bracelet, an electronic necklace, an electronic tattoo, an electronic device, or a smart watch).

The electronic apparatus 100 may also be any of a number of electronic devices including, but not limited to, cellular phones, smart phones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, cameras, other media recorders, radios, medical devices, vehicle transportation equipment, calculators, programmable remote controllers, pagers, laptop computers, desktop computers, printers, netbook computers, Personal Digital Assistants (PDAs), Portable Multimedia Players (PMPs), moving Picture experts group (MPEG-1 or MPEG-2) Audio layer 3(MP3) players, portable medical devices, and digital cameras, and combinations thereof.

In some cases, electronic device 100 may perform multiple functions (e.g., playing music, displaying videos, storing pictures, and receiving and sending telephone calls). If desired, the electronic apparatus 1000 may be a portable device such as a cellular telephone, media player, other handheld device, wrist watch device, pendant device, earpiece device, or other compact portable device.

The housing 10 has a substantially rectangular parallelepiped shape. The housing 10 is a carrier of the electronic device 100, and is used for carrying most parts of the electronic device 100. The housing 10 may be made of plastic, a metal material, or a plastic and a metal formed into a unitary structure by an in-mold molding process. In one embodiment, the substrate 12 is made of metal and the wall 14 is made of plastic.

The manufacturing method of the shell 12 comprises the following steps: the housing 10 is obtained by placing the substrate 12 in a mold, and then injecting molten plastic into the mold to form the walls 14 after the plastic is solidified.

The touch display screen 20 may include a display screen 21 and a cover 22, the cover 22 covering the display screen 21. The display screen 21 is a flexible display screen such as an OLED (Organic Light-Emitting Diode). Of course, the display 21 may be a liquid crystal display. The cover 22 covering the display screen 21 can reduce the impact on the display screen. The touch display screen 20 may be secured to the front side of the substrate 12 by adhesive.

The touch screen 20 can receive external touch input to generate corresponding signals, so that the touch screen 20 can operate in different states. For example, if the touch display screen 20 receives a click input while the touch display screen 20 is playing video content, the touch display screen 20 may pause playing the video.

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 is reflected by the object 200, the reflected infrared light is transmitted to the infrared receiver 34 through the light-transmitting hole 142, and the infrared receiver 34 generates a corresponding electrical signal 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 emitter 33 and the received infrared light, and thus control the display state of the touch display screen 20.

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

As shown in fig. 1, the electronic device 100 includes a processor 40, and the processor 40 is configured to control a display state of the touch display screen 20 according to the infrared light received by the infrared receiver 30. In one example, when the user is receiving or making a call and brings the electronic device 100 close to the head, the processor 40 generates the detection information by calculating the time when the proximity sensor 30 emits infrared light and receives infrared light reflected back by the object 200. 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 the present embodiment, the proximity sensor 30 may be fixed to the substrate 12 by a component such as a bracket, or the proximity sensor 30 may be fixed to another component of the electronic device 100.

The light passing hole 142 is, for example, a straight hole, or the inner surface of the light passing hole 142 is linear in the axial direction of the light passing hole 142. Of course, the inner surface of the light passing hole 142 may be curved or broken in the axial direction of the light passing hole 142. The infrared light emitted from the proximity sensor 30 may pass through the light passing hole 142 and then exit to the front side of the touch display screen 20.

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

Referring to fig. 3, in one example, the axis 1422 of the light passing hole 142 may be vertically disposed. It should be noted that although the axis 1422 of the light passing hole 142 is vertically disposed, since the infrared light emitted from the infrared emitter 33 is inclined, the infrared light emitted from the infrared emitter 33 can also be transmitted to the front side of the touch display screen 20 to detect whether an object blocks the touch display screen 20 on the front side of the touch display screen 20.

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

In this embodiment, the light-passing hole 142 is located at the top of the surrounding wall 14. That is, the light passing hole 142 is located at the top of the electronic device 100. The "top" referred to herein is: when the electronic device 100 is in the upright normal use state, the electronic device 100 is located at the end far away from the ground. Alternatively, the "top" is an end portion on one side in the longitudinal direction of the electronic device 100. Of course, the light-passing hole 142 may be located at other positions of the surrounding wall 14, for example, the light-passing hole 142 is located at the bottom or the side of the surrounding wall 14.

In the present embodiment, the "front side" is a side where infrared light generated by the touch display panel 20 is emitted to the outside of the electronic device 100. For example, when the user views 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 back 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 screen 20. The infrared light emitted from 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 housing space 16, that is, the proximity sensor 30 is disposed in the housing 10.

Referring to fig. 3, in some embodiments, the emission axis 31 of the ir emitter 33 passes through the light passing hole 142, and the emission axis 31 of the ir emitter 33 is inclined from the ir 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 infrared light emitted by the infrared emitter 33 has a smaller angle with the horizontal direction, and thus the infrared light emitted by the infrared emitter 33 can be emitted to the object 200 in front of the touch display screen 20 to detect whether the object 200 approaches the touch display screen 20.

It will be appreciated that the infrared emitter 33 emits infrared light having a certain emission angle. The emission angle of the infrared emitter 33 is the 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 from the infrared emitter 33 can exit 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 proximate to the proximity sensor 30. The second port 1426 is distal from the proximity sensor 30. The emission optical axis 31 of the infrared emitter 33 passes through the middle position of the second aperture 1426.

Referring to fig. 3, in some embodiments, the 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, for example, 30 degrees, 35 degrees, 40 degrees, 50 degrees, 60 degrees, or the like. When the included angle a is within the above angle range, the infrared light emitted by the infrared emitter 33 can be emitted from the light passing hole 142 to the front side of the touch display screen 20 more, so as to detect whether an object 200 blocks the touch display screen 20.

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

Referring to fig. 3, 7 and 8, in some embodiments, the proximity sensor 30 further includes a circuit board 32, and the circuit board 32 is disposed horizontally. The infrared transmitter 33 and the infrared receiver 34 are both provided on the circuit board 32. The emission optical axis 31 of the infrared emitter 33 is disposed obliquely 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 horizontally disposed, and the emission optical axis 31 of the infrared emitter 33 is disposed obliquely 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 the emission optical axis 31 of the infrared emitter 33 can be tilted toward the front side of the substrate 12 after passing through the light passing hole 142, so that the infrared light emitted from the infrared emitter 33 can be emitted to the front side of the touch display screen 20.

The oblique arrangement of the emission optical axis 31 of the infrared emitter 33 with respect to the circuit board 32 means that: the emission optical axis 31 of the infrared emitter 33 is not perpendicular to the circuit board 32, and the emission optical axis 31 of the infrared emitter 33 forms an acute angle b with respect to the surface of the circuit board 32.

Alternatively, the angle b between the emission optical axis 31 of the infrared emitter 33 and the circuit board 32 is smaller than 90 degrees. In one example, the emission optical axis 31 of the infrared emitter 33 is at an angle b of 30-60 degrees to the circuit board 32. For example, the included angle b is 30 degrees, 35 degrees, 45 degrees, 50 degrees, or 60 degrees. It will be appreciated that when the circuit board 32 is horizontally disposed, 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), and the horizontal arrangement of the circuit board 32 means that the upper surface of the circuit board 32 is in a horizontal state, or the thickness direction of the circuit board 32 is in a vertical state.

Referring to fig. 5, in some embodiments, the circuit board 32 of the proximity sensor 30 is disposed obliquely with respect to the horizontal. The infrared transmitter 33 and the infrared receiver 34 are both provided on the circuit board 32. The infrared emitter 33 is for emitting infrared light, the infrared receiver 34 is for receiving infrared light, 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 inclined toward the front side of the substrate 12.

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 vertically 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 the emission optical axis 31 of the infrared emitter 33 can be tilted toward the front side of the substrate 12 after passing through the light passing hole 142, so that the infrared light emitted from the infrared emitter 33 can be emitted to the front side of the touch display screen 20.

It is 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 from the infrared emitter 33 has a certain emission angle, the infrared light emitted from the infrared emitter 33 may be inclined with respect to the circuit board 32.

Referring to fig. 5 and 9, in one example, the circuit board 32 is inclined at an angle c of 30-60 degrees with respect to the horizontal direction. For example, the angle c is an angle of 30 degrees, 35 degrees, 45 degrees, 50 degrees, or 60 degrees.

Referring also to fig. 10-12, in some embodiments, the infrared emitter 33 includes a light emitting source 331 and a light transmissive element 332. The light emission source 331 is provided on the circuit board 32. The light transmitting member 332 covers the light emitting source 331. Light-transmitting element 332 includes front light-transmitting portion 3321 and rear light-transmitting portion 3322 connected to 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. Rear light-transmitting portion 3322 is located on the rear side of emission optical axis 31 of light emission source 331. The infrared receiver 34 is located on the side of the light emission source 331. The proximity sensor 30 further includes a light shielding member 35, and the light shielding member 35 covers at least a part of the rear light-transmissive portion 3322.

In this way, the light blocking element 35 blocks at least part of the rear transparent portion 3322, so that the infrared light emitted from the front transparent portion 3321 can be more concentrated, the energy of the infrared light emitted from the front transparent portion 3321 is increased, the distance of the infrared light emitted from the front transparent portion 3321 is further increased, the infrared light is also favorably reflected back to the infrared receiver 34 after hitting the object 200, and the detection capability of the proximity sensor 30 is improved.

In particular, the light transmissive element 332 may be made of a light transmissive material. For example, the material of the light-transmitting member 332 is resin or glass. The light transmitting member 332 houses the light emitting source 331, or the light emitting source 331 is disposed in the light transmitting member 332. Thus, the light-transmitting element 332 can protect the light-emitting source 331 and avoid the problem that the light-emitting source 331 is damaged due to contact with oxygen.

Note 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 from the light emitting source 331 sequentially passes through the front light emitting portion and the light passing hole 142 and then reaches the front side of the touch display screen 20 to detect whether the touch display screen 20 is blocked.

Light blocking element 35 extends from the left side to the right side of rear translucent portion 3322. That is, both the left rear portion and the right rear portion of the rear translucent portion 3322 are covered. The light blocking element 35 is an element having a function of blocking infrared light, such as foam, a black ink layer, or a metal layer.

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

Referring to fig. 6, in some embodiments, the front transparent portion 3321 is disposed adjacent to the touch display screen 20. Rear light-transmissive portion 3322 is disposed away from touch display screen 20. The light emitting source 331 is for emitting infrared light to the front side of the substrate 12 through the front light-transmitting portion 3321 and the light-transmitting hole 142.

In this manner, the proximity sensor 30 can operate normally to detect whether the object 200 is hidden 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 horizontally disposed. At this time, the infrared light emitted from the infrared emitter 33 is emitted from the front translucent portion 3321 of the translucent member 332, passes through the translucent hole 142, and is emitted to the front side of the touch display panel 20.

Referring to fig. 12, in some embodiments, light blocking element 35 covers the entirety of rear light-transmissive portion 3322. Or, the light blocking member 35 completely covers the rear transparent portion 3322, and at this time, the infrared light emitted from 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 member 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 close to the emission optical axis 31 is shielded by the light-shielding member 35, and the infrared light emitted from the light-emitting source 331 is emitted from a portion far from the emission optical axis 31.

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

Of course, in some embodiments, light blocking element 35 covers a portion of rear light-transmissive portion 3322.

Referring to fig. 12, in some embodiments, an angle d between the infrared light emitted from the front transparent portion 3321 and the emission optical axis 31 of the light emission source 331 is 30 to 60 degrees. In other words, in this case, the emission angle of the infrared emitter 33 is 30 to 60 degrees. For example, the included angle d is 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, or 60 degrees.

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

Referring also to fig. 7, 10-11, in some embodiments, the proximity sensor 30 includes a housing 36, the housing 36 housing the infrared emitter 33 and the infrared receiver 34. Enclosure 36 includes a top plate 361 and side plates 362 extending from edges of 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 emitter 33 and the infrared receiver 34 are exposed.

In this manner, the cover 36 may protect the infrared emitter 33 and the infrared receiver 34, thereby improving the life of the proximity sensor 30. Cover 36 may be made of a relatively rigid material, for example, the material of cover 36 is metal, and specifically, the material of cover 36 is stainless steel, for example. Cover 36 may be formed by a stamping process to form top plate 361 and side plates 362, thereby forming cover 36.

Referring to fig. 7, 10-11, in some embodiments, the housing 36 further includes a light barrier 363, and the light barrier 363 is configured to couple with the top plate 361 and isolate the infrared emitter 33 from the infrared receiver 34. In this way, the light blocking plate 363 can prevent the infrared light emitted from the infrared emitter 33 from directly transmitting to the infrared receiver 34, and thus the normal operation of the infrared receiver 34 is affected.

It will be appreciated that if the infrared light emitted by the infrared emitter 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 erroneously controls the display state of the touch display screen 20.

The light blocking plate 363 is made of a light blocking material, and the light blocking plate 363 may be integrated with the top plate 361. Alternatively, the top plate 361, the light blocking plate 363, and the side plate 362 may be formed by a press bending process.

Referring to fig. 7, 10-11, in some embodiments, the circuit board 32 is formed with a recess 321, and an end of the light blocking plate 363 away from the top plate 361 is inserted into the recess 321. Therefore, the groove 321 can not only locate the position of the cover 36 through the light blocking plate 363, but also enable the cover 36 to be more stably installed on the circuit board 32, which is beneficial to improving the stability of the proximity sensor 30. Specifically, the groove 321 is in a strip shape, the groove 321 is matched with the light blocking plate 363, and the size of the groove 321 is slightly larger than that of the light blocking plate 363 so that the light blocking plate 363 can be inserted into the groove 321.

Referring to fig. 2 and 3 again, in some embodiments, the electronic device 100 includes the light guide pillar 50 filled in the light through hole 142. Thus, the light guide pillar 50 is beneficial to guiding infrared light to the front side of the substrate 12, and can also reduce foreign matters such as dust and liquid from the outside from entering the electronic device 100 to damage the electronic device 100. It is understood that the light guide bar 50 is made of a light-transmitting material, for example, the material of the light guide bar 50 is silica gel or resin.

The light guide pillar 50 and the housing 10 may be formed as separate bodies. For example, when the light guide 50 is inserted into the light passing hole 142 after the housing 10 and the light guide 50 are separately molded, a slight gap is formed between the light passing hole 142 and the light guide 50. Of course, the light guide bar 50 and the housing 10 may be formed integrally, for example, after the light through hole 142 is formed on the surrounding wall 14, the melted light guide material is injected into the light through hole 142, and after the light guide material is solidified, the light guide bar 50 integrated with the surrounding wall 14 is formed, so that the light guide bar 50 and the surrounding wall 14 are difficult to separate.

Referring to FIG. 6, in some embodiments, the wall 14 includes an outer side 144, and the light guide 50 includes a top surface 52 facing the outer side of the housing 10, the top surface 52 smoothly transition to interface with the outer side 144. This may improve the aesthetics of the electronic device 100. By smooth transition abutment, it is meant that the difference in height formed at the abutment of the top surface 52 and the outer side surface 144 is very small or zero.

Referring to fig. 3 again, in some embodiments, the light hole 142 includes a first opening 1424 and a second opening 1426, the first opening 1424 is close to the proximity sensor 30, the second opening 1426 is far from the proximity sensor 30, and the electronic device 100 further includes a light-transmitting body 60, and the light-transmitting body 60 covers and seals the first opening 1424.

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

In one example, the light-transmissive body 60 is in the form of a sheet, and the light-transmissive body 60 may be fixed to the inside of the wall 14 by an adhesive. This allows the optically transparent body 60 to seal the second opening 1426 because the adhesive has a sealing effect.

Referring to fig. 2 again, in some embodiments, the light-transmitting body 60 and the light guide pillar 50 are integrally formed. For example, the light-transmitting body 60 and the light guide bar 50 are made of resin, so that the light-transmitting body 60 and the light guide bar 50 can be integrally formed by in-mold casting. In one example, the assembly process of the light guide 50 includes: the light guide 50 extends from the inside of the housing 10 into the light hole 142 so that the light-transmitting body 60 abuts against the inside of the surrounding wall 14.

Referring to fig. 2 and 3, in some embodiments, the electronic device 100 further includes an electroacoustic element 70, and the electroacoustic element 70 is disposed adjacent to the proximity sensor 30. The substrate 12 has an acoustic channel 122 for the electroacoustic component 70 to emit sound to the front side of the substrate 12.

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

In summary, the electronic device 100 according to the embodiment of the invention includes a housing 10, a touch display 20, and a proximity sensor 30. The housing 10 includes a substrate 12 and a sidewall 14 extending backward from an edge of the substrate 12, the substrate 12 and the sidewall 14 together enclose an accommodating space 16, and the sidewall 14 is opened with a light-passing hole 142 communicating with the accommodating space 16. The touch display screen 20 is provided on the front side of the substrate 12.

The proximity sensor 30 is disposed in the housing space 16, and the proximity sensor 30 includes a circuit board 32, an infrared transmitter 33, and an infrared receiver 34 of the proximity sensor 30. The circuit board 32 is disposed obliquely with respect to the horizontal direction. The infrared transmitter 33 and the infrared receiver 34 are both provided on the circuit board 32. The infrared emitter 33 is for emitting light to the front side of the substrate 12 through the light passing hole 142, and the infrared receiver 34 is for receiving light from the front side of the substrate 12.

In the electronic device 100 according to the embodiment of the invention, the circuit board 32 is obliquely arranged, so that the infrared emitter 33 emits light to the front side of the substrate 12 through the light through hole 142 located in the side wall 14, and the infrared receiver 34 receives the light from the front side of the substrate 12, so that the electronic device 100 can control the touch display screen 20 to operate according to the signal of the proximity sensor 30, and the proximity sensor 30 does not occupy the front side space of the substrate 12, thereby avoiding the interference between the proximity sensor 30 and the touch display screen 20, and improving the screen occupation ratio of the electronic device 100.

In some embodiments, the circuit board 32 is angled from the horizontal by an angle c of 30-60 degrees. For example, the angle c is an angle of 30 degrees, 35 degrees, 45 degrees, 50 degrees, or 60 degrees.
