Under more and more large-screen display scenes, the acquisition of images and sounds through a display is needed, such as audio and video conferences, station portrait capturing, restaurant audiovisual monitoring and the like. However, most of the large-screen displays in the related art have only a single image display function, and in order to acquire images and sounds based on the display, it is necessary to connect a camera module and a microphone module to the large-screen display. However, the camera component and the microphone component are usually separated and connected with the large screen display through the USB data line, which easily causes wiring disorder after connection and has poor integration level, and the existing microphone component is difficult to realize clear voice communication in a noisy environment.

In order to realize high integration of a camera assembly and a microphone assembly, the embodiment of the application provides an audio and video integrated device. As shown in fig. 1, the audio/video integrated device 1 includes a casing 11, a camera module 12 and a microphone module 13, wherein the camera module 12 and the microphone module 13 are both located inside the casing 11;

the housing 11 includes a first housing wall 111 and a second housing wall 112 opposite to each other, the first housing wall 111 has an opening 113 and a first sound hole set 114, and the opening 113 and the first sound hole set 114 are both communicated with the inside of the housing 11.

The lens 121 of the camera module 12 is exposed from the opening 113;

the microphone module 13 includes a microphone body 131 and a sealing element 132, the microphone body 131 is fixed on the second casing wall 112, and a second sound hole set 133 is opened on the microphone body 131; the sealing member 132 is interposed between the first case wall 111 and the microphone body 131, and one end of the sealing member 132 surrounds the first sound hole group 114 and the other end surrounds the second sound hole group 133.

The housing 11 is a structure for accommodating the camera module 12 and the microphone module 13. The housing 11 has an inner cavity, and the camera module 12 and the microphone module 13 are both located inside the housing 11 and are fixedly connected to the housing 11.

As shown in fig. 2, in some embodiments of the present application, the housing 11 further includes a first supporting seat 115 and a second supporting seat 116, and the first supporting seat 115 and the second supporting seat 116 are connected to the second housing wall 112, wherein the first supporting seat 115 is used for supporting and fixing the camera module 12, and the second supporting seat 116 is used for supporting and fixing the microphone module 13.

For example, the first supporting base 115 may be provided with a first screw hole and a second screw hole, the second sidewall of the housing 11 is provided with a third screw hole, and the camera module 12 is provided with a fourth screw hole. During assembly, the first supporting seat 115 is fixed on the second shell wall 112 by using screws to pass through the first screw hole and the third screw hole; another screw is used to pass through the second screw hole and the fourth screw hole, thereby fixing the camera module 12 to the first supporting seat 115 and further to the housing 11. Correspondingly, the second supporting seat 116 may be provided with a fifth screw hole and a sixth screw hole, the second side wall of the casing 11 may be provided with a seventh screw hole, and the microphone module 13 is provided with an eighth screw hole. During assembly, the second support seat 116 is fixed on the second shell wall 112 by using screws to pass through the fifth screw hole and the seventh screw hole; another screw is used to pass through the sixth screw hole and the eighth screw hole, so that the microphone module 13 is fixed on the second support base 116 and thus on the housing 11.

The camera module 12 is a module for image acquisition. The camera module 12 may include a lens 121, an image sensor, and a circuit board, wherein the lens 121 is fixed on the circuit board and exposed from the opening 113 of the first wall 111 of the middle housing 11, so as to capture an image; the image sensor is disposed corresponding to the lens 121 so that an image of an object to be photographed generated through the lens 121 can be projected onto a surface of the image sensor to generate an electrical signal, and the image sensor is electrically connected to the circuit board. In some embodiments, the fourth screw hole may be opened on the circuit board.

The microphone module 13 is a module for performing sound collection. The microphone module 13 may include a microphone body 131 and a sealing element 132, wherein the microphone body 131 may effectively collect sound entering from the second sound hole set 133, and the sealing element 132 surrounds the second sound hole set 133. The layout and acoustic design of the microphone module 13 is such that a tight acoustic seal is achieved between the microphone body 131 and the housing 11 on the basis of the sealing element 132. Specifically, on the one hand, the sealing element 132 can ensure that the position of the sound center is fixed, and sound can effectively enter from the position of the first sound hole group 114 opposite to the second sound hole group 133 instead of the gap around the second sound hole group 133, so that noise around the second sound hole group 133 is effectively isolated, and the sound collection definition is improved; on the other hand, the sealing element 132 can also serve to reduce vibration, thereby reducing noise transmitted into the microphone by structural vibrations, such as interference with the fan and power supply of the display device.

Therefore, according to the audio/video integrated device 1 provided by the embodiment of the application, the camera module 12 and the microphone module 13 are arranged inside the casing 11, so that the audio/video integrated device 1 is highly integrated and compact in structure, when the audio/video integrated device 1 needs to be used, the casing 11 of the audio/video integrated device 1 is directly fixed on a display, and then the audio/video integrated device 1 is electrically connected with the display, so that the number of wires connected with the display is obviously reduced. Moreover, the microphone module 13 in the audio/video integrated device 1 is sealed by the sealing element 132 around the sound hole to ensure that the sound center is a fixed sound hole, and sound enters the microphone body 131 through the first sound hole group 114 and the second sound hole group 133, so that the influence caused by ambient noise is effectively reduced, and meanwhile, due to the soft material of the sealing element 132, the influence caused by structural vibration is also reduced, and the transmission quality of sound is improved.

As shown in fig. 3, in some implementations of embodiments of the present application, the sealing element 132 may be a sealing gasket, and the first sound hole set 114 and the second sound hole set 133 communicate through an inner space 1321 of the sealing gasket.

The sealing washer is made of soft materials, such as rubber, silicon rubber and the like, so that good sound insulation and vibration reduction effects are achieved. The sealing washer has a ring-shaped structure and has an inner space 1321, wherein the shape of the inner space 1321 enclosed by the inner side wall of the sealing washer includes, but is not limited to, a circle, and may also be a strip, a square, an ellipse, and the like. In the present embodiment, the circumferential dimension of the inner sidewall of the sealing gasket, as defined at 1321, is no less than the circumferential dimension of the acoustic aperture or acoustic apertures in the acoustic aperture set that it is intended to surround.

For example, in some embodiments of the present application, a sealing gasket may be disposed for the first sound hole set 114 and the second sound hole set 133, the sealing gasket surrounds the first sound hole set 114 and the second sound hole set 133, in this case, an inner space 1321 surrounded by an inner side wall of the sealing gasket may be in a shape of a strip, and a circumferential length of the strip-shaped inner space 1321 may be greater than or equal to a circumferential dimension of the first sound hole set 114.

For another example, with continued reference to fig. 3, in other embodiments of the present application, the first acoustic port set 114 may include at least one first acoustic port 1141, the second acoustic port set 133 may include at least one second acoustic port 1331, and the first acoustic port 1141 and the second acoustic port 1331 communicate through the interior space 1321 of the sealing element 132. That is, a sealing gasket is disposed for each first sound hole 1141 in the first sound hole group 114, the sealing gasket surrounds the first sound hole 1141 and the corresponding second sound hole 1331, the shape of the inner space 1321 surrounded by the inner side wall of the sealing gasket may be circular, and the circumferential length of the circular inner space 1321 may be greater than or equal to the circumferential size of the first sound hole 1141.

The thickness of the sealing gasket is generally larger than the gap between the microphone body 131 and the first wall 111 of the housing 11, so that the sealing gasket is compressed and clamped between the two structures, thereby tightly sealing the gap between the microphone body 131 and the first wall 111 of the housing 11, and the inner space 1321 of the sealing gasket forms a passage for allowing sound to enter the second sound hole set 133 from the first sound hole set 114.

In the embodiment of the present invention, the first sound hole 1141 and the second sound hole 1331 may be formed as a single hole, or may be formed as a plurality of holes, a square shape, a groove shape, a louver shape, or the like.

It should be noted that the number of the at least one first sound hole 1141 included in the first sound hole group 114 and the number of the at least one second sound hole 1331 included in the second sound hole group 133 may be the same or different. When the number of the first sound holes 1141 is the same as that of the second sound holes 1331, at least one first sound hole 1141 and at least one second sound hole 1331 are generally in a one-to-one correspondence relationship; when the number of the first sound holes 1141 is different from that of the second sound holes 1331, there may be a case where one first sound hole 1141 corresponds to a plurality of second sound holes 1331 (or one second sound hole 1331 corresponds to a plurality of first sound holes), and the other end of the sealing gasket surrounds one first sound hole 1141 and the other end of the sealing gasket surrounds a plurality of second sound holes 1331 (or one end of the sealing gasket surrounds one second sound hole 1331 and the other end of the sealing gasket surrounds a plurality of first sound holes 1141).

In the embodiment of the present application, the microphone body 131 may be a high signal-to-noise ratio microphone, such as a MEMS (Micro-Electro-Mechanical Systems) microphone, which is a rear sound outlet type microphone. As shown in fig. 4, in one possible design, the microphone body 131 includes a PCB (Printed Circuit Board) Board, an integrated Circuit chip 1312, and at least one acoustic sensor 1313. The PCB 1311 is electrically connected to the integrated circuit chip 1312, the second sound hole 1331 is formed in the PCB 1311, and the eighth screw hole may also be formed in the PCB 1311; an integrated circuit chip 1312 is mounted on the PCB 1311 and electrically connected to the at least one acoustic sensor 1313; each acoustic sensor 1313 is located in a second sound bore 1331. Since the position of the acoustic center corresponds to the position of the second sound hole 1331, when the acoustic sensor 1313 is located in the second sound hole 1331, the sound collecting effect is the best, and the collected sound is the clearest.

Of course, in other embodiments of the present application, the microphone body 131 may also be of other types, such as a front sound outlet type microphone.

As shown in fig. 5, the number of the microphone modules 13 in the embodiment of the present application may be two, and the two microphone modules 13 are respectively located at two sides of the camera module 12; the number of the first sound hole sets 114 is two, and the two first sound hole sets 114 are respectively located at two sides of the opening 113 and respectively correspond to the two microphone modules 13.

The two microphone modules 13 collect sounds in a certain range together, and the sounds are distributed on two sides of the camera module 12, so that the sounds on two sides of the camera module 12 can be clearly and uniformly collected, and the situations that the sounds received by people at different positions are unbalanced and the sounds received by parts of the people are not clear when in audio communication can be avoided. And the camera is positioned in the center of the device, so that clear portrait capture can be realized.

Therefore, the audio and video integrated device 1 provided by the embodiment of the application has good audio and video acquisition effects in far-field voice pickup, real-time voice communication, voice recognition, video recording, portrait capturing and the like in audio and video conference scenes and other complex scenes.

In one possible design, as shown in FIG. 6, any two adjacent first acoustic holes 1141 in each first acoustic hole set 114 may be spaced apart by 5-50mm, which may be 20mm, 30mm, or 40mm, for example.

In one possible design, as shown in FIG. 6, the two first acoustic holes 1141 of the two first acoustic hole sets 114 closest to the opening 113 have a pitch of 30-300mm, which may be 80mm, 140mm, or 200mm, for example.

In one possible design, as shown in FIG. 6, the number of first sound holes 1141 in each first sound hole group 114 is four, and the spacing between the two first sound holes 1141 of the two first sound hole groups 114 farthest from port 113 is 60-600mm, which may be 100mm, 260mm, or 420mm, for example. That is, the microphone module 13 may include 8 sound sensors, thereby improving noise reduction capability and reverberation reduction capability.

Each sound sensor can correspond to one sealing element 132, so that a good acoustic sealing effect is achieved, the upper limit of the working frequency band of the microphone module 13 can be close to the highest frequency (20kHz) in the audible range of human ears, the performance consistency of each sound sensor is guaranteed, the AI noise reduction algorithm is facilitated to achieve the optimal performance, various surrounding complex noises are effectively eliminated, and the transmission quality of sound is improved.

Referring to fig. 3 and 4, in some embodiments of the present application, the first sound hole 1141 and the second sound hole 1331 have the same diameter, wherein each of the first sound holes 1141 has a diameter in a range of 1-5mm, an outer side of the first housing wall 111 is spaced from the acoustic sensor 1313 by a distance in a range of 0.5-5mm, and the outer side is a side of the first housing wall 111 away from the microphone module 13. Therefore, in the acoustic frequency response test of the microphone module 13, the acoustic resonance peak is located near 18kHz and is far larger than the effective bandwidth upper limit of broadband (8kHz) or ultra-wideband (14kHz) voice communication, resonance can be effectively reduced, the transmission quality of sound is greatly guaranteed, and the accuracy of algorithm and signal processing in subsequent application is also achieved. The acoustic frequency response test result of the microphone module 13 is shown in fig. 7. Illustratively, in the present application, each first sound hole 1141 has a diameter of 2mm, and the outer side surface of the first housing wall 111 is spaced from the acoustic sensor 1313 by 3mm, which corresponds to the best acoustic frequency response test result of the microphone module 13.

To sum up, the audio and video integrated device 1 provided by the embodiment of the present application sets the camera module 12 and the microphone module 13 inside the casing 11, and is highly integrated and compact in structure, and when the device is needed to be used, the casing 11 of the audio and video integrated device 1 is directly fixed on a display, and then the audio and video integrated device 1 is electrically connected with the display, so that the number of wires connected with the display is obviously reduced. Moreover, the microphone module 13 in the audio/video integrated device 1 is sealed by the sealing element 132 around the sound hole, so as to ensure that the sound center is a fixed sound hole, and the sound enters the microphone body 131 through the first sound hole group 114 and the second sound hole group 133, thereby effectively reducing the influence caused by the surrounding environmental noise, and meanwhile, due to the soft material of the sealing element 132, the influence caused by the structural vibration is also reduced, and the transmission quality of the sound is improved.

In the embodiment of the application, the display body 2 has an image display function, and the audio and video integrated device 1 has image acquisition and sound acquisition functions, so that the display can be suitable for audio and video call scenes. The audio and video integrated device 1 can be installed on the display body 2 in a clamping, screw connection, magnetic connection and other modes, circuit wiring of the audio and video integrated device 1 is completed, and then the audio and video integrated device 1 is started; when the audio and video call is finished or the audio and video integrated device 1 needs to be maintained, the connection between the display body 2 and the audio and video integrated device 1 can be released, and the audio and video device can be detached from the display body 2. Alternatively, the display body 2 and the audio/video integrated device 1 may be connected together in a non-detachable manner, for example, the housing 11 of the audio/video integrated device 1 and the housing 11 of the display body 2 may be an integrally formed structure.

In some implementations of the embodiment of the present application, the audio/video integrated device 1 may be fixed on the top of the display body 2, and the first wall 111 of the casing 1 of the audio/video integrated device 1 faces the same direction as the screen of the display body 2.

In some embodiments of the present application, the camera module 12 of the audio/video integrated device 1 is located in the middle of the display body 2 in the length direction of the display body 2.

For example, in an audio-video conference scene, when the audio-video integrated device 1 is located in the center of the top of the display body 2, since the position of the camera module 12 is relatively high, most or even all of the participants in the conference room can be brought into the image acquisition range, thereby helping to better carry out the conference. Moreover, since the participants usually face the display during the conference, the microphone module 13 can more clearly collect the voices of the participants directly in front of the display (i.e. the positions of the participants), thereby improving the communication quality.
