Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure as recited in the claims below.

At present, a speaker (speaker) is disposed in an intelligent device, and the speaker can be used for voice communication, music playing and other services. As users demand higher and higher sound quality, more and more manufacturers provide sound chambers for speakers, thereby making the sound of the speakers more pleasant. However, with the addition of the acoustic cavity, the volume of the speaker becomes large, which is a challenge in designing ultra-thin smart devices.

In the process of implementing the scheme of the application, the inventor of the application finds that: in the telephoto lens, a long distance exists between the lens and the image sensor, and in practice, the lens can be extended and retracted to compress the length in the optical axis direction, but an unused space is included in the telephoto lens.

Therefore, the disclosed embodiment provides a telephoto lens, and the conception is that an audio module is arranged in a space where the lens module is not utilized, so that the volume occupied by separately arranging the telephoto lens and the audio module can be reduced, and the miniaturization and ultrathin design of electronic equipment is facilitated; and, set up the sound chamber in the audio frequency module, be favorable to promoting the low frequency effect of the sound that the audio frequency module broadcast.

Fig. 1 is a block diagram illustrating a telephoto lens according to an exemplary embodiment, and fig. 2 is a cross-sectional view of the telephoto lens in the a-a' direction illustrated according to an exemplary embodiment. Referring to fig. 1 and 2, a telephoto lens 10 includes a lens holder 110, a lens barrel 120, a lens module 130 disposed on the lens barrel 120, and an audio module 140; a first space 150 is formed among the lens base 110, the lens module 130 and the lens barrel 120; the audio module 140 includes a speaker 141 and a sound cavity 142 disposed above the speaker 141, the speaker 141 is disposed above the lens barrel 120, and the sound cavity 142 is disposed in the first space 150.

It can be understood that the space occupied by the optical lens 131 moving along the optical axis is an effective space, and the effective space needs to be reserved for the lens module 130, wherein the effective space is also regarded as a part of the lens module 130. In other words, the space enclosed by the lens module 130, the lens barrel 120 and the lens base 110 is the unused space of the lens module 130, and the unused space of the lens module 130 is the first space 150. In practical applications, the diameter of the lens barrel 120 of the telephoto lens 10 away from the lens holder 110 is larger, i.e. the closer the first space 150 is to the lens module 130, the larger the corresponding space is. Therefore, in the embodiment of the disclosure, in a case that a sufficient moving space is left for the lens module 130, the distance between the sound cavity 142 and the lens module 130 is as small as possible, for example, a preset threshold (e.g., 0.5mm-2mm) is preset, so that the distance between the sound cavity 142 and the lens module 130 is smaller than or equal to the preset threshold, and thus the larger the volume of the sound cavity 142 is, the better the low-frequency effect is.

In the embodiment of the present disclosure, the speaker 141 and the sound cavity 142 in the audio module 140 may be disposed in a dispensing or embedding manner, that is, the sound cavity 142 is directly fixed or detachably fixed on the speaker 141. Of course, the skilled person can also adopt other arrangements, for example, integral molding, and in the case of realizing the arrangement of the speaker 141 and the acoustic cavity 142, the corresponding solutions fall into the scope of protection of the present application.

In the embodiment of the present disclosure, the speaker 141 may be disposed inside the lens barrel 120, for example, on the lens barrel 120 around the first space 150. To ensure sound to be smoothly transmitted to the outside of the lens barrel 120 of the telephoto lens 10, a mounting hole (not shown) is formed on the lens barrel 120. Thus, the speaker 141 can be installed in the installation hole, and the effect of fixing the speaker 141 and smoothly transmitting sound is achieved.

It should be noted that the speaker 141 of the above embodiment may be fixedly installed in the installation hole, and the shape of the installation hole may be the same as or similar to the shape of the speaker 141, such as a circle or a rectangle. Of course, the speaker 141 may also be fixed in the mounting hole in a movable mounting manner, in this manner, the mounting hole may be configured as a long strip, and the speaker 141 may move in the optical axis direction, and the moving direction is the same as the moving direction of the lens module 130. The speaker 141 can be moved manually by a user, and can also be moved synchronously with the lens module 130, i.e., the lens module moves to drive the sound cavity to move, thereby driving the speaker to move. It is understood that the above solutions all fall within the scope of protection of the present application.

In consideration of the application scenario of the telephoto lens 10, the speaker 141 and the wall of the barrel around the mounting hole are made of light blocking materials or light absorbing materials. Taking the light absorbing material as an example, the surface of the wall of the lens barrel around the speaker 141 and the mounting hole may be coated with a layer of black material, so as to prevent external light from entering the lens barrel from around the speaker 141, the mounting hole or the mounting hole, thereby achieving the effect of absorbing light and ensuring the imaging effect of the subsequent image sensor.

In the embodiment of the present disclosure, a screw or a buckle may be disposed on the lens holder 110, and the telephoto lens 10 may be fixed on the electronic device 20 by the screw or the buckle. Of course, the skilled person can also adopt other arrangements, and in the case that the arrangement of the telephoto lens 10 on the electronic device 20 can be realized, the corresponding solution falls within the scope of protection of the present application.

In the embodiment of the disclosure, the lens module 130 may include an optical lens 131 and a first motor 132, wherein the optical lens 131 may be disposed on the first motor 132, and the optical lens 131 may move along the optical axis direction under the action of the first motor, so as to achieve focusing. The moving distance D of the optical lens 131 can be adjusted according to the focal length of the telephoto lens 10.

Since the first space 150 is located above the optical axis of the telephoto lens 10, in this embodiment, when the sound cavity 142 is disposed above the optical axis, a high transmittance material may be used, where the high transmittance material may include at least one of the following materials: optical polymer material, glass. For example, the optical polymer material may include, but is not limited to, a PC board, an acryl PMMA board. It is understood that any material capable of achieving a high light transmittance of the sound cavity 142 falls within the scope of the present application, and the present application is not limited thereto.

In addition, it should be noted that, in order to ensure that the audio module 140 has a better low-frequency effect, the sound cavity 142 may be configured as a hollow closed structure, that is, the inside of the sound cavity 142 is a closed space. It will be appreciated that materials with high light transmittance, which have the effect of facilitating sealing, also fall within the scope of the present application.

Fig. 3 is a block diagram illustrating a telephoto lens according to an exemplary embodiment, and based on the telephoto lens shown in fig. 1 or fig. 2, referring to fig. 3, a telephoto lens 10 further includes a prism 160, and the prism 160 is disposed at a side of the lens module 130 away from the sound cavity 142 for adjusting the direction of the light path. For example, in a case where the user holds the electronic device and the display screen of the electronic device is directly facing the user, the telephoto lens 10 may be disposed along the left-right direction of the user, and due to the effect of the prism 160 changing the direction of the light path, the viewing angle of the telephoto lens may be located on the side where the display screen is located (i.e., the front lens) or on the side away from the display screen (i.e., the rear lens), which is beneficial to further reducing the thickness of the electronic device.

With continued reference to fig. 3, in the embodiment of the present disclosure, the telephoto lens 10 is further provided with a second motor 170, and the second motor 170 is used for driving the prism 160 to rotate along a plane perpendicular to the optical axis (i.e., XOY plane) to realize optical anti-shake. The anti-shake principle can be referred to the related art, and is not described herein.

To this end, in the embodiment of the disclosure, the audio module is disposed in the telephoto lens, the speaker in the audio module is disposed on the lens barrel, and the sound cavity of the audio module is disposed in a first space formed among the lens base, the lens module and the lens barrel, wherein the first space is an idle space. Due to the arrangement of the sound cavity, the low-frequency effect of sound transmitted to the outside of the telephoto lens by the loudspeaker is better. In addition, the space occupied by independently arranging the telephoto lens and the audio module can be reduced in the embodiment of the disclosure, which is beneficial to designing miniaturized and ultra-thinned electronic products.

Fig. 4 is a block diagram illustrating a telephoto lens according to an exemplary embodiment, and based on the telephoto lens illustrated in fig. 1, 2, or 3, referring to fig. 4, a telephoto lens 10 further includes an infrared filter 180; the infrared filter 180 is disposed on a side of the sound cavity 142 away from the lens module 130. The infrared filter 180 may be made of colored glass or may be a plastic infrared filter, and the corresponding scheme falls within the scope of the present application in the case of filtering.

In practical application, considering that the infrared filter 180 is not easy to be cut into a circular shape, the infrared filter 180 can be cut into a rectangular shape in the embodiment and integrated on the lens base 110, so that the difficulty of the production process is reduced on the premise of ensuring the light filtering effect.
