[0046] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0047] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] In the present invention, unless otherwise clearly stipulated and limited, the first feature being "on" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through another feature between them.

[0049] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0050] Video conference system, also known as TV conference system, refers to a system device that enables two or more individuals or groups in different places to communicate with each other through transmission lines and multimedia equipment, such as voice, image and file data, to achieve instant and interactive communication and achieve the purpose of the meeting. Video conference can be used to communicate with multiple people at the same time, and people can also talk face to face.

[0051] In a video conference call, audio and video equipment is needed to collect the voices and images of the participants and transmit them to audio playback and display devices. The audio and video equipment in the existing technology usually has the problem of being unable to capture the image of the person whose sound is picked up, resulting in the lack of synchronization between the audio and the picture, causing communication difficulties in remote communication.

[0052] In view of the defects of the prior art, the present invention provides a microphone array structure with a sound source indication function, Figure 1-8 As shown, the microphone array structure includes: a shell 1, a microphone array board 2 and a light-emitting component 3.

[0053] The housing 1 includes a housing cavity for accommodating the microphone array board, and side panels and a bottom panel 15 . The bottom panel 15 and the microphone array board 2 are arranged in parallel, and the side panels and the bottom panel 15 constitute a part of the housing cavity.

[0054] The side of the side plate facing away from the accommodating cavity is the light incident side A of the housing 1 , and the light emitting component 3 is combined and fixed to the light incident side A of the housing 1 .

[0055] The side of the bottom plate 15 facing away from the accommodating cavity is the light emitting side B of the shell 1. The light emitting side B is provided with a light display block 17 which is formed by the bottom plate 15 protruding in the direction away from the accommodating cavity. The light display block 17 is made of transparent material. The light emitted by the light-emitting component 3 can be displayed on the bottom plate 15 through the light display block 17. When the light display block 17 lights up, it indicates that the microphone array board 2 of the corresponding microphone array structure is collecting sound sources.

[0056] In a specific embodiment, the housing 1 is made of a transparent material. When the microphone array structure is installed on the audio and video integrated machine, the bottom plate 15 is arranged toward the user. When the microphone array board 2 captures a voice signal, the light emitted by the light-emitting component 3 enters the accommodating cavity from the light-incident side A of the housing 1, and the light-display block 17 on the bottom plate 15 will show light, indicating that the microphone array board on the corresponding side is working.

[0057] In a preferred example, the accommodating cavity is at least partially covered with a reflective layer (not shown in the figure), which can increase the reflection of light in the accommodating cavity, but will not affect the structure of the various parts of the shell 1. Specifically, the accommodating cavity is covered with a reflective layer except for the portion corresponding to the light incident side A and the light display block 17, so as to guide the transmission of the light source in the accommodating cavity so that the light can be correctly displayed at the light display block 17. Furthermore, the outer surface of the shell 1 is at least partially coated with an opaque layer (not shown in the figure), which can be a black topcoat or other light-absorbing coating. Specifically, the outer surface of the shell 1 is coated with an opaque layer except for the light incident side and the light display block 17. The provision of the opaque layer can increase the contrast between the display block 17 and the surroundings, bringing a brighter look and feel, making it easier to be recognized by users, and playing an indicating role.

[0058] A microphone array board refers to an arrangement structure of microphones in a plate-like form, which is composed of a certain number of acoustic sensors (generally microphones), which are arranged on the board according to certain shape rules (such as linear or array), and are used to collect and transmit voice signals. The microphone array board 2 in the embodiment of the utility model includes four microphones 21 on the board, and the four microphones are linearly arranged on the microphone array board 2, and are located on the contact surface between the microphone array board 2 and the bottom plate 15.

[0059] In one embodiment, the side panel includes a first side panel 11 and a third side panel 13 located at two opposite sides in the width direction of the bottom panel 15. Specifically, the first side panel 11 and the third side panel 13 are respectively fixed to the two wide sides of the bottom panel 15. The ends of the first side panel 11 and the third side panel 13 away from the bottom panel 15 include a buckle portion 16 extending toward the inner side of the accommodating cavity along the length direction of the bottom panel 15. The buckle portion 16 is used to fix the microphone array panel 2 in the accommodating cavity to prevent the microphone array panel 2 from falling out.

[0060] Specifically, Figure 6As shown, the buckle portion 16 located on the first side plate 11 and the buckle portion 16 located on the third side plate 13 have a guide slope 160 at one end close to each other, and the guide slope 160 is set to be inclined downward. The size of the microphone array plate 2 is similar to the internal size of the accommodating cavity. When assembling the microphone array plate 2 with the shell 1, the microphone array plate 2 is placed above the shell 1, parallel to the bottom plate 15, and the microphone array plate 2 is pressed down. Under the action of the guide slope 160, the microphone array plate 2 slides down along the guide slope 160. The first side plate 11 and the third side plate 13 have a certain elastic deformation ability. During the process of the microphone array plate 2 moving down along the guide slope 160, the first side plate 11 and the third side plate 13 are inclined away from each other, so that the microphone array plate 2 can be smoothly installed in the accommodating cavity. After the microphone array plate 2 is installed in place, the first side plate 11 and the third side plate 13 are reset under the action of internal stress. The buckle portion 16 is located on the side of the microphone array plate 2 away from the bottom plate 15, which is used to limit the microphone array plate 2 in the accommodating cavity. Figure 6 The degree of freedom in the Y direction prevents the microphone array board 2 from falling out.

[0061] In one embodiment, the side panel includes a second side panel 12 and a fourth side panel 14 located on two opposite sides in the length direction of the bottom panel 15. Specifically, the second side panel 12 and the fourth side panel 14 are located between the first side panel 11 and the third side panel 13, and are respectively combined and fixed to the two long sides of the bottom panel 15.

[0062] In this embodiment, the side of the second side panel 12 and the fourth side panel 14 facing away from the accommodating cavity is the light incident side A of the shell 1. Specifically, the side of the second side panel 12 facing away from the velvet safety can be set as the light incident side A, and the light-emitting component 3 is combined and fixed to the side of the second side panel 12 facing away from the accommodating cavity, and is used to illuminate the user to prompt the direction of the sound source when the microphone array plate 2 captures the sound source.

[0063] The side of the fourth side panel 14 facing away from the accommodating cavity can also be set as the light incident side A. In this case, the light-emitting component 3 is combined and fixed to the side of the fourth side panel 14 facing away from the accommodating cavity, and is used to illuminate the direction of the sound source to prompt the user when the microphone array board 2 captures the sound source.

[0064] In this embodiment, Figure 2 As shown, the second side plate 12 is arranged as the light incident side A.

[0065] Further, such as Figure 4-6As shown, in a specific embodiment, the first side panel 11 is separated from the second side panel 12 and the fourth side panel 14 on both sides corresponding to the second side panel 12 and the fourth side panel 14. That is, at least a part of the two sides of the first side panel 11 is not connected to the second side panel 12 and the fourth side panel 14, so that the first side panel 11 has elastic deformation ability and has the ability to shift in a direction away from the third side panel 13, so that the microphone array panel 2 can be smoothly installed in the accommodating cavity. In a preferred example, the first side panel 11 is formed by the upward protrusion of the bottom panel 15, is located between the second side panel 12 and the fourth side panel 14, is not connected to the second side panel 12 and the fourth side panel 14, and includes a gap 110 between the first side panel 11 and the second side panel 12 and the fourth side panel 14.

[0066] Correspondingly, the third side panel 13 is the same as the first side panel 11. The sides of the third side panel 13 corresponding to the second side panel 12 and the fourth side panel 14 are also partially separated from the second side panel 12 and the fourth side panel 14. That is, at least a part of the two sides of the third side panel are not connected to the second side panel 12 and the fourth side panel 14, so that the third side panel 13 has elastic deformation energy and has the ability to shift in the direction away from the first side panel 11, so that the microphone array panel 2 can be smoothly installed in the accommodating cavity. In a preferred example, the third side panel 13 is formed by an upward protrusion of the bottom plate 15, and is located between the second side panel 12 and the fourth side panel 14. It is not connected to the second side panel 12 and the fourth side panel 14, and there is a gap 130 between the third side panel 13 and the second side panel 12 and the fourth side panel 14. It should be noted that the upward protrusion described in this embodiment refers to the protrusion along Figure 6 The Y direction is raised.

[0067] In the present embodiment, when the microphone array plate 2 is assembled with the shell 1, the microphone array plate 2 moves downward along the guide bevel 160. Since the two sides of the first side plate 11 and the third side plate 13 are not fixed and only the bottom is fixed to the bottom plate 15, the microphone array plate 2 can push the first side plate 11 and the third side plate 13 to tilt away from each other during the process of moving downward along the guide bevel 160, so that the microphone array plate 2 can be smoothly installed in the accommodating cavity. After the microphone array plate 2 is installed in place, the first side plate 11 and the third side plate 13 are reset under the action of internal stress. The buckle portion 16 is located on the side of the microphone array plate 2 away from the bottom plate 15, and is used to limit the microphone array plate 2 in the Figure 1 The degree of freedom in the X direction prevents the microphone array board 2 from falling out.

[0068] In a specific embodiment, Figure 6As shown, one side surface of the second side panel 12 and the fourth side panel 14 located in the accommodating cavity includes a limiting portion 18 protruding into the accommodating cavity, and the microphone array panel 2 includes a limiting groove (not shown) arranged to correspond to the limiting portion 18. One of the second side panel 12 and the fourth side panel 14 includes two limiting portions 18, and the other includes one limiting portion 18. The unequal numbers of the limiting portions 18 on the two side panels is equivalent to an anti-foolproof design, which can play a positioning role when the microphone array panel 2 is installed, and prevent the microphone array panel from being installed upside down. When the microphone array panel 2 is installed in the accommodating cavity, each limiting portion 18 just fits into the corresponding limiting groove, which can limit the microphone array panel 2 in the accommodating cavity. Figure 6 The degree of freedom in the X direction prevents the microphone array board 2 from shaking randomly in the housing 1.

[0069] In one embodiment, when the microphone array board 2 is installed in the accommodating cavity, the distance between the end surface of the microphone array board 2 close to the first side plate 11 and the inner wall surface of the first side plate 11 is 0.2 mm; the distance between the end surface of the microphone array board 2 close to the third side plate 13 and the inner wall surface of the third side plate 11 is 0.2 mm. This allows a certain gap to exist between the microphone array board 2 and the first side plate 11 and the third side plate 13. Since the microphone array board 2 is assembled into the accommodating cavity by pressing, this gap helps to reduce friction and resistance during the assembly process, and can also compensate for dimensional changes caused by factors such as manufacturing errors, material deformation or temperature changes to a certain extent, and can also facilitate the disassembly and maintenance of the microphone array board 2.

[0070] In this embodiment, the microphone array board 2 includes four microphones 21, and the microphones 21 are arranged protruding from the surface of the microphone array board 2. A sound cavity hole 151 is provided on the bottom plate 15, and the sound cavity hole 151 is arranged one-to-one with the microphone 21. The microphone 21 is installed in the sound cavity hole 151. The microphone head of the microphone 21 is provided with a sound cavity 4. The sound cavity 4 improves the performance of the microphone 21 by changing the acoustic environment around the microphone head. The sound cavity 4 is generally a closed or semi-closed space located around the microphone head. The main function of the sound cavity 4 is to change the acoustic environment around the microphone head, thereby improving the directivity, frequency response and signal-to-noise ratio of the microphone. For example, the sound field distribution around the microphone head can be changed by adjusting the parameters such as the shape, size and material of the sound cavity, so that the microphone is more sensitive to sound signals in a specific direction, and has better suppression ability for sound signals in other directions, so that the sound source can be more accurately located in a complex environment, and useful sound signals can be extracted.

[0071] In a specific embodiment, Figure 1 as well as Figure 7As shown, the light-emitting component 3 includes a plate body 31 and a plurality of light-emitting points 32 installed on the side of the plate body 31. The plate body 31 is fixed to the light-incident side A of the housing 1. Specifically, the light-emitting points 32 are arranged between two adjacent microphones 21. When the microphone array board 2 includes four microphones 21, there is one light-emitting point 32 between two adjacent microphones 21, and three light-emitting points 32 are arranged on the plate body 31. Preferably, the light-emitting points 32 can be LED lights.

[0072] In one embodiment, the light-entering side A of the housing 1 includes a light-entering block 19 that is formed by protruding in a direction away from the accommodating cavity. The light-entering block 19 and the light-emitting point 32 are arranged one by one, and the light-emitting point 32 is fixed to one end of the light-entering block 19 away from the side plate where it is located. Specifically, the light-emitting point 32 is an LED lamp, and the light-emitting side of the LED lamp is bonded and fixed to the light-entering block 19. The housing 1 is made of transparent PC material as a whole, which can achieve the function of guiding light on the basis of ensuring structural strength. When the microphone array board 2 collects a voice signal, the light-emitting component 3 is controlled to be energized, the LED lamp emits light, and the light enters the accommodating cavity through the light-entering block 19. At this time, each light-entering block 19 is the brightest part of the housing 1. After entering the accommodating cavity, the light diverges to the surroundings, and the brightness gradually decreases. Therefore, the light-entering block 19 and the light display block 17 are arranged in correspondence to ensure that the light-emitting surface of the light display block 17 has sufficient brightness to play an indicating role. Preferably, the part of the light-entering side A except the light-entering block 19 can also be coated with an opaque layer to prevent the divergence of light from affecting the brightness of the display block 17.

[0073] Another embodiment of the utility model provides an audio and video integrated machine, combined with Fig.14 As shown, the audio and video integrated machine includes a display device 5, an image acquisition device (not shown), and a microphone array structure 7 with a sound source indication function provided in the above embodiment, which is fixed to the front frame of the display device 5 through an adapter 6.

[0074] In order to more accurately capture and transmit voice signals and improve voice quality and clarity, the integrated audio and video machine generally has at least two groups of microphone array structures, each of which includes four microphones 21 on the microphone array board 2, and the two groups of microphone array structures are arranged on the left and right sides of the front frame of the display device 5. When the light display block 17 of one of the two groups of microphone array structures is bright, it indicates that the direction corresponding to the group of microphone array structures is the direction of the user's sound source, and the image acquisition device can realize the function of automatic capture and even anti-speaker influence, thereby realizing audio and video synchronization and more convenient remote communication.

[0075] The adapter 6 is a sheet metal part used to mount the microphone array structure on the display device 5. Fig. 9As shown, the adapter 6 includes a connecting plate 61, a mounting plate formed by bending one side of the connecting plate 61 upward, and a fixing ear 63 formed by bending the other side of the connecting plate 61 upward. The microphone array structure is fixed to the mounting plate, the fixing ear 63 is fixed to the non-display side of the display device 5, and the connecting plate 61 is parallel to the bottom surface of the display device 5, thereby realizing the assembly of the microphone array structure and the display device 5.

[0076] When the microphone array structure is connected to the adapter 6, the bottom plate 15 is parallel to the mounting plate, and the microphone array structure is fixed to the side of the mounting plate away from the connecting plate 61. Figure 9-13 As shown, the mounting plate includes five bending walls, which are the first bending wall 621, the second bending wall 622, the third bending wall 623, the fourth bending wall 624 and the fifth bending wall 625.

By connecting the positioning hole 22 of the microphone array plate 2 to the positioning column 64 accordingly, the microphone array structure can be positioned on the adapter plate 6, and then the microphone array structure and the adapter plate 6 are fixed.

[0078] Specifically, the first bending wall 621, the third bending wall 623 and the fifth bending wall 625 are all provided with a penetrating first mounting hole 65. Correspondingly, the bottom plate 15 is provided with a countersunk hole 152 corresponding one to one with the first mounting hole 65, and the microphone array board 2 is provided with a connecting hole 23 corresponding to the countersunk hole 152. The countersunk hole 152, the connecting hole 23 and the first mounting hole 65 are connected by screws to lock the microphone array board 2 and the shell 1 to the adapter plate 6.

[0079] The second bending wall 622 and the fourth bending wall 624 are both provided with a second mounting hole 66 that penetrates therethrough. Correspondingly, the plate body 31 of the light-emitting component 3 is provided with connecting through holes 33 that correspond one to one with the second mounting holes 66. The through holes 33 and the second mounting holes 66 are connected by screws to lock the light-emitting component 3 to the adapter plate 61.

[0080] The microphone array structure and audio-video integrated machine with sound source indication function provided by the embodiment of the utility model connect the microphone array board with the light-emitting component by designing the structure of the shell, and realize the function of indicating when the microphone array board is in the sound pickup state by the layout of the light-emitting component and the design of the optical path. When applied to the audio-video integrated machine, the light display block corresponding to the microphone array board that captures the speaker's voice signal will light up, thereby playing the role of indicating the speaker's direction. In conjunction with the image acquisition device, the speaker's direction is automatically captured, which can achieve audio and video synchronization during remote communication, making communication more convenient.

[0081] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention.
