DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In order to make the technical solutions and advantages of the present application clearer, the camera module and electronic equipment will be described in detail in combination with the drawings.

[0050] With the development of electronic technology, the requirements for the audio performance of electronic devices are getting higher and higher. Electronic devices are often equipped with multiple microphones to achieve the function of receiving sound. In the related art, the microphone on the back of the electronic device is set near the decorative part, and the through hole for receiving or outputting sound is usually opened on the lens or on the side wall of the decorative part. The former seriously affects the exquisite appearance of the whole machine, while the latter has a more complex structure and higher cost.

[0051] In this regard, the present application provides a camera module, such as Figure 1 and Figure 2 As shown, the camera module may include a first decorative piece 1, a carrier 2, an acoustic device 3, a second decorative piece 4 and a transparent cover 5; the first decorative piece 1 is connected to the carrier 2, and a receiving cavity 11 is formed between the first decorative piece 1 and the carrier 2, the acoustic device 3 is arranged in the receiving cavity 11 and is connected to the carrier 2; the second decorative piece 4 surrounds the transparent cover 5, and the second decorative piece 4 is connected to the first decorative piece 1 on the side of the first decorative piece 1 away from the carrier 2, wherein a sound receiving gap 12 is formed between the second decorative piece 4 and the first decorative piece 1, and the first decorative piece 1 is provided with a sound receiving hole 111, and the sound receiving gap 12 is connected to the receiving cavity 11 through the sound receiving hole 111.

[0052] In the camera module provided in the embodiment of the present application, a sound receiving gap 12 is formed between the first decorative member 1 and the second decorative member 4. The sound receiving gap 12 and the acoustic device 3 inside the accommodating cavity 11 are communicated through a sound receiving hole 111. When it is necessary to collect the sound signal outside the electronic device, the sound is sequentially received by the acoustic device 3 after passing through the sound receiving gap 12 and the sound receiving hole 111, completing the acquisition of the sound signal and obtaining high-quality audio. Compared with the method of collecting sound signals by opening holes in the lens or decorative member in the related art, the camera module provided in the embodiment of the present application does not need to open holes in the lens or decorative member. After the first decorative member 1 and the second decorative member 4 are assembled, the sound receiving gap 12 can be formed between the first decorative member 1 and the second decorative member 4, and the structure is relatively simple and does not affect the appearance delicacy of the whole machine.

[0053] It should be noted that the first decorative member 1 and the second decorative member 4 are stacked in the thickness direction of the electronic device, and the open side of the sound receiving gap 12 is located on the side of the camera module (the side provided with the transparent cover 5 is the front). That is, when the user views the electronic device straight from the back of the electronic device, it is not easy to observe the sound receiving gap 12, ensuring the appearance delicacy of the electronic device.

[0054] In some embodiments, the acoustic device 3 may include a microphone and a speaker. The microphone is used to collect the external sound signal, and the speaker is used to play audio. Therefore, the above-mentioned sound receiving gap 12 can also be called an out-sound gap, and the sound receiving hole 111 can also be called an out-sound hole. In the camera module provided in the embodiment of the present application, a sound receiving channel (which can also be called an out-sound channel) is formed between the sound receiving gap 12 (out-sound gap), the sound receiving hole 111 (out-sound hole) and the acoustic device 3. The sound signal enters the acoustic device 3 from the outside through the sound receiving channel, and the audio played by the acoustic device 3 can also be transmitted to the outside through the out-sound channel.

[0055] In some embodiments, a photographic device may also be provided in the accommodating cavity 11. The photographic device is installed on the carrier 2. Through holes (not shown in the figure) are opened on both the first decorative member 1 and the second decorative member 4. The external light enters the photographic device after passing through the transparent cover 5, the through hole on the first decorative member 1, and the through hole on the second decorative member 4.

[0056] Optionally, the first decorative member 1 is a plastic decorative member or a metal decorative member. Exemplarily, the first decorative member 1 is a plastic decorative member, which can reduce the weight of the camera module.

[0057] Optionally, the second decorative member 4 is a plastic decorative member or a metal decorative member. Exemplarily, the second decorative member 4 is a metal decorative member, which has high structural strength and is not easily damaged, avoiding damage to internal electronic components due to external bumps.

[0058] Optionally, the first decorative member 1 is an integrally formed member; and / or, the second decorative member 4 is an integrally formed member, which has a simple structure and can save manufacturing costs.

[0059] Optionally, the carrier 2 is an antenna bracket.

[0060] In one example, as Figure 2 shown, the first decorative member 1 has a first surface 13 facing the second decorative member 4, and the second decorative member 4 has a second surface 41 facing the first decorative member 1, wherein: a first groove 131 is formed on the first surface 13, the first groove 131 extends to the outer edge of the first decorative member 1, the sound receiving hole 111 is opened on the bottom wall of the first groove 131, and there is a gap between the bottom wall and the second surface 41 to form a sound receiving gap 12 between the first decorative member 1 and the second decorative member 4; a second groove 42 is formed on the second surface 41, the second groove 42 extends to the outer edge of the second decorative member 4, and there is a gap between the bottom wall of the second groove 42 and the first surface 13 to form a sound receiving gap 12 between the first decorative member 1 and the second decorative member 4.

[0061] In the camera module provided by the embodiment of the present application, by providing the first groove 131 on the first surface 13 of the first decorative member 1 and / or providing the second groove 42 on the second surface 41 of the second decorative member 4, a sound receiving gap 12 is formed between the first decorative member 1 and the second decorative member 4. When the acoustic device 3 works, the external sound signal can be conducted to the acoustic device 3 through the sound receiving gap 12 to achieve effective sound reception.

[0062] In one example, as Figure 2 shown, a first groove 131 is formed on the first surface 13 of the first decorative member 1, and the above-mentioned sound receiving gap 12 is formed between the bottom wall of the first groove 131 and the second decorative member 4.

[0063] In another example, as Figure 3 shown, a second groove 42 is formed on the second surface 41 of the second decorative member 4, and the above-mentioned sound receiving gap 12 is formed between the bottom wall of the second groove 42 and the first decorative member 1.

[0064] In another example, a first groove 131 is formed on the first surface 13 of the first decorative member 1, and a second groove 42 is formed on the second surface 41 of the second decorative member 4. The above-mentioned sound receiving gap 12 is formed between the bottom walls of the first groove 131 and the second groove 42. Compared with the above two examples, the size of the sound receiving gap 12 in the thickness direction of the camera module is larger in this example, and the sound receiving effect is better.

[0065] In some embodiments of the present application, as Figure 4 and Figure 5As shown, the first groove 131 includes a connected first groove section 1311 and a second groove section 1312. The first groove section 1311 is arranged farther from the outer edge of the first decorative member 1 than the second groove section 1312, and the groove depth of the second groove section 1312 is greater than that of the first groove section 1311. That is, the dimension of the sound receiving gap 12 near the edge of the camera module is greater than the dimension of the sound receiving gap 12 near the sound receiving hole 111. In other words, the dimension of the sound receiving gap 12 on the side closer to the outside world is larger, which can better receive external sound signals.

[0066] In some embodiments of the present application, as Figure 5 shown, the bottom wall of the first groove 131 includes a first bottom wall 13111 of the first groove section 1311, a connecting surface 1313, and a second bottom wall 13121 of the second groove section 1312 that are connected in sequence. The connecting surface 1313 is smoothly and transitionally connected to the first bottom wall 13111 and the second bottom wall 13121 respectively. That is, the bottom wall of the first groove 131 is a smooth surface, which can effectively reduce the reflection of sound in the groove wall of the first groove 131. When sound is reflected, echoes and reverberations will be generated, which will affect the clarity and quality of recording. The smooth surface can make the reflected sound waves scatter or absorb more evenly, thus avoiding the generation of reverberation.

[0067] In some embodiments, the bottom wall of the first groove 131 includes an inclined surface that is inclined towards the outer edge of the first decorative member 1. Then, the farther away from the second decorative member 4, the sound receiving gap 12 gradually becomes larger along the extending direction of the first groove 131, which can better receive external sound signals.

[0068] In some embodiments of the present application, as Figure 6 、 Figure 7 and Figure 9 shown, the camera module may further include a cover plate 6 and a third decorative member 7; the cover plate 6 is covered on the carrier 2, and an installation hole 61 is formed on the cover plate 6. The first decorative member 1 and the second decorative member 4 pass through the installation hole 61 and are located inside the installation hole 61; the third decorative member 7 is arranged on the side of the cover plate 6 away from the carrier 2 and is arranged around the first decorative member 1 and the second decorative member 4. There is a first gap 71 between the third decorative member 7, the first decorative member 1, and the second decorative member 4, and the first gap 71 is communicated with the accommodation cavity 11 through the sound receiving gap 12.

[0069] In the camera module provided in the embodiment of the present application, a third decorative member 7 is additionally provided outside the first decorative member 1 and the second decorative member 4. The first decorative member 1, the second decorative member 4, and the third decorative member 7 have a first gap 71. One end of the first gap 71 communicates with the outside world, and the other end communicates with the sound receiving gap 12. The external sound signal can enter the acoustic device 3 after passing through the first gap 71, the sound receiving gap 12, and the sound receiving hole 111 in sequence. The audio emitted by the acoustic device 3 can also be conducted to the outside world after passing through the sound receiving hole 111, the sound receiving gap 12, and the first gap 71 in sequence, realizing the functions of sound receiving and sound output; moreover, the opening direction of the open side of the first gap 71 is parallel to the thickness direction of the camera module. When the user takes an image, the side of the camera module provided with the transparent cover plate 5 faces the object to be photographed. At this time, the opening direction of the first gap 71 also directly faces the object to be photographed, which can receive the sound signal more directly and effectively, improving the sound receiving efficiency.

[0070] In some embodiments of the present application, as Figure 8 shown, the second decorative member 4 may include a plate body 43 and a side plate 44 surrounding the plate body 43. A part of the side plate 44 protrudes away from the plate body 43 to form a first flanging 441. The first flanging 441 is parallel to the cover plate 6 and is connected or abutted against the surface of the third decorative member 7 away from the cover plate 6; a third groove 4411 is formed on the surface of the first flanging 441 facing the third decorative member 7. There is a second gap 72 between the bottom wall of the third groove 4411 and the third decorative member 7. The second gap 72 communicates with the first gap 71.

[0071] The first flanging 441 on the second decorative member 4 is parallel to the cover plate 6 and is connected to the third decorative member 7, which is equivalent to closing the open side of the first gap 71. A third groove 4411 is formed on the first flanging 441, and a second gap 72 is formed between the third groove 4411 and the third decorative member 7. A sound receiving channel is formed among the sound receiving gap 12, the first gap 71, and the second gap 72. The end of the sound receiving channel away from the acoustic device 3 is open, and the opening direction is perpendicular to the thickness direction of the camera module. The open side of the sound receiving channel is located on the side of the camera module. Compared with the above solution where the opening direction of the open side of the first gap 71 is parallel to the thickness direction of the camera module, it may sacrifice part of the sound receiving performance, but greatly improves the appearance delicacy.

[0072] In some embodiments of the present application, as Figure 2 and Figure 9As shown, the camera module may further include a first seal 8. The first seal 8 is attached to the first surface 13 of the first decorative member 1 and is connected to or abuts against the second decorative member 4 to seal the gap between the first decorative member 1 and the second decorative member 4. Wherein, a through hole 81 is formed in the first seal 8, and the orthographic projection of the first groove 131 on the projection plane at least partially overlaps with the orthographic projection of the through hole 81 on the projection plane, and the projection plane is parallel to the first surface 13.

[0073] To ensure the airtightness of the sound receiving channel, a first seal 8 may be provided between the first decorative member 1 and the second decorative member 4, thereby effectively sealing the first decorative member 1 and the second decorative member 4. And, to avoid the first seal 8 affecting the sound receiving effect, a through hole 81 is additionally formed in the first seal 8, and the sound signal can enter the sound receiving gap 12 through the through hole 81, ensuring airtightness while also enabling good sound receiving and sound output.

[0074] In some embodiments, the orthographic projection of the first groove 131 on the projection plane is located inside the orthographic projection of the through hole 81 on the projection plane, further reducing the negative impact of the first seal 8 on the sound receiving effect and ensuring the sound receiving effect while achieving effective sealing.

[0075] Optionally, the first seal 8 is a sealing foam or a sealing rubber. Those skilled in the art can select and adjust the type of the first seal 8 according to actual needs.

[0076] In some embodiments of the present application, as Figure 2 and Figure 9 shown, the side of the first decorative member 1 close to the carrier 2 extends away from the acoustic device 3 to form a second flanging 14, and the second flanging 14 extends into the space between the cover plate 6 and the carrier 2. The camera module further includes a second seal 9, and the second seal 9 is located between the second flanging 14 and the cover plate 6 and abuts against the second flanging 14 and the cover plate 6 respectively to seal the gap between the second flanging 14 and the cover plate 6.

[0077] To ensure the airtightness of the sound receiving channel, a second seal 9 may be provided between the cover plate 6 and the second flanging 14 of the first decorative member 1 to effectively seal the first decorative member 1 and the cover plate 6, thereby ensuring the sound receiving effect of the acoustic device 3.

[0078] Optionally, the second seal 9 is a sealing foam or a sealing rubber. Those skilled in the art can select and adjust the type of the second seal 9 according to actual needs.

[0079] The present application also provides an electronic device, and the electronic device includes the above-mentioned camera module.

[0080] In the electronic device provided by the embodiment of the present application, a sound collection gap 12 is formed between the first decorative member 1 and the second decorative member 4. The sound collection gap 12 and the acoustic device 3 inside the accommodation cavity 11 are communicated through a sound collection hole 111. When it is necessary to collect the sound signals outside the electronic device, the sound is sequentially received by the acoustic device 3 after passing through the sound collection gap 12 and the sound collection hole 111, completing the acquisition of the sound signals and obtaining high-quality audio. Compared with the method of collecting sound signals by opening holes in the lens or decorative member in the related art, the camera module provided by the embodiment of the present application does not need to open holes in the lens or decorative member. After the first decorative member 1 and the second decorative member 4 are assembled, the sound collection gap 12 can be formed between the first decorative member 1 and the second decorative member 4. The structure is relatively simple and does not affect the appearance delicacy of the whole machine.

[0081] Moreover, due to the adoption of the above camera module, the electronic device provided by the embodiment of the present application can ensure the appearance delicacy while meeting the requirements of sound collection and sound output, improving the user experience.

[0082] Optionally, the electronic device may be a device with a photography function such as a mobile phone, a computer, a tablet, etc.

[0083] In the present application, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. The term "plurality" means two or more, unless otherwise clearly defined.
