Description

Technical Field

[0001] The present application relates to the field of audio and video technology, and in particular to an audio and video recording device. Background Art

[0002] In existing teaching recording and conference scenarios, cameras must not only record the entire audience but also provide close-up recordings of the speaker. Similarly, microphones must capture both the entire audience and the speaker.

[0003] In the relevant technical field, although panoramic cameras, omnidirectional microphones, zoom cameras and directional microphones can be integrated into audio and video recording equipment, the sound pickup effect of a single directional microphone in a fixed position is poor, resulting in poor clarity of the speaker's sound picked up by the directional microphone. Utility Model Content

[0004] An embodiment of the present application provides an audio and video recording device, which aims to integrate a panoramic camera, an omnidirectional microphone, a zoom camera and a directional microphone into the audio and video recording device, and allows multiple directional microphones to be arranged around the side of the skylight, thereby further optimizing the sound pickup effect of the directional microphone and improving the clarity of the speaker's sound pickup.

[0005] An embodiment of the present application provides an audio and video recording device, which includes a base assembly and a pan-tilt assembly. The base assembly includes a base body, a panoramic camera and an omnidirectional microphone, and the panoramic camera and the omnidirectional microphone are arranged at intervals on the base body; the pan-tilt assembly includes a shell, a zoom camera and multiple directional microphones; the zoom camera and the directional microphones are both connected to the shell, and the shell has a light-collecting port and multiple sound pickup holes. The multiple sound pickup holes are arranged around the light-collecting port, and the directional microphones are arranged in a one-to-one correspondence with the sound pickup holes. The zoom camera can shoot through the light-collecting port, and the directional microphones are arranged in correspondence with the sound pickup holes. The shell is connected to the base body and can move relative to the base body so that the zoom camera and the directional microphones are aimed at the speaker for audio and video recording.

[0006] Based on the above embodiment, a panoramic camera, an omnidirectional microphone, a zoom camera, and a directional microphone are integrated into an audio and video recording device. Only the installation of the audio and video recording device needs to be completed to realize the installation of the panoramic camera, the omnidirectional microphone, the zoom camera, and the directional microphone, thereby reducing the difficulty of arrangement and improving the convenience of installation. When a meeting or lecture is held, the panoramic camera can capture a panoramic video of all participants, and the omnidirectional microphone can collect the voices of all participants. When there is a speaker among the participants, the omnidirectional microphone obtains the speaker's audio signal, and the controller can determine the speaker's spatial position based on the audio signal. The controller controls the shell to move relative to the base body so that the zoom camera and the directional microphone can be aimed at the speaker. The controller can control the zoom camera to focus on the speaker and take a close-up picture of the speaker. The directional microphone can carry out directional sound pickup of the speaker, thereby improving the sound pickup effect of the speaker.

[0007] Furthermore, since there are multiple directional microphones, each corresponding to a sound pickup hole, the use of multiple directional microphones can optimize the sound pickup effect of the directional microphones and improve the clarity of the speaker's voice. Furthermore, the multiple sound pickup holes are spaced around the light opening, allowing the multiple directional microphones to surround the light opening, further optimizing the sound pickup effect of the directional microphones and improving the clarity of the speaker's voice.

[0008] In some embodiments, the shell further has an installation cavity, the light-collecting port and the sound pickup hole are both connected to the installation cavity, and the zoom camera and the directional microphone are both arranged in the installation cavity.

[0009] Based on the above embodiment, the zoom camera and the directional microphone are arranged in the installation cavity, and the shell can be used to protect the zoom camera and the directional microphone to reduce the probability of damage to the zoom camera and the directional microphone, so that the zoom camera and the directional microphone can have a longer service life, and thus the audio and video recording equipment can have a longer service life.

[0010] In some embodiments, the pan-tilt assembly further includes an annular circuit board, which is connected to the shell and disposed in the mounting cavity. The annular circuit board is arranged around the light opening, and a plurality of directional microphones are arranged at intervals on the annular circuit board.

[0011] Based on the above embodiment, by arranging the annular circuit board around the light opening and arranging the directional microphone on the annular circuit board, so that the directional microphone is arranged around the light opening, the sound pickup effect of the directional microphone can be optimized and the sound pickup clarity of the speaker can be improved.

[0012] In some embodiments, there are multiple omnidirectional microphones, and two adjacent omnidirectional microphones are arranged at intervals.

[0013] Based on the above embodiment, the use of multiple omnidirectional microphones can improve the recording effect of the entire sound field, and compared with only one omnidirectional microphone, the controller can determine the spatial position of the speaker through multiple omnidirectional microphones, thereby facilitating the controller to control the movement of the shell so that the zoom camera and the directional microphone are aimed at the speaker, thereby improving the positioning accuracy of the speaker, improving the aiming accuracy of the zoom camera and the directional microphone, and improving the accuracy of the zoom camera in obtaining close-up images of the speaker and the directional microphone in picking up the speaker's directional sound.

[0014] In some embodiments, the omnidirectional microphone and the panoramic camera are disposed on the same side of the base body.

[0015] Based on the above embodiment, since the omnidirectional microphone and the panoramic camera are arranged on the same side of the base body, the synchronization between the audio signal obtained by the omnidirectional microphone and the video signal obtained by the panoramic camera is improved.

[0016] In some embodiments, the pan-tilt assembly further includes a support member, which is rotatably connected to the base body and capable of rotating around a first direction relative to the base body; the shell is rotatably connected to the support member and capable of rotating around a second direction relative to the support member, and the first direction is perpendicular to the second direction.

[0017] Based on the above embodiment, by controlling the base body to rotate around a first direction and by controlling the shell to rotate around a second direction, the zoom camera and the directional microphone can move on the surface of the spherical shell, so as to increase the movement range of the zoom camera and the directional microphone, thereby ensuring that the zoom camera and the directional microphone can both be aimed at the speaker, so as to improve the shooting clarity of the zoom camera of the speaker and improve the accuracy of the directional microphone's directional sound pickup of the speaker.

[0018] In some embodiments, a side of the support member away from the base body has an avoidance groove, and the shell is rotatably connected to the groove wall of the avoidance groove.

[0019] Based on the above embodiment, the shell is rotatably connected to the groove wall of the avoidance groove, which can reduce the space occupied by the shell around the audio and video recording device, so that the overall volume of the audio and video recording device is smaller, thereby facilitating the production and transportation of the audio and video recording device.

[0020] In some embodiments, the audio and video recording device further includes a first driving device, which is disposed on the base body, and an output shaft of the first driving device is connected to the support member so that the support member can rotate around a first direction.

[0021] Based on the above embodiment, the first driving device is used to drive the support member to rotate around the first direction, so that the zoom camera and the directional microphone can both rotate around the first direction. Specifically, the first driving device may include a motor, the motor is connected to the base body, and the output shaft of the motor is connected to the support member to facilitate driving the support member to rotate. In other embodiments, the first driving device may also include a motor and a reducer connected to the motor, the output shaft of the reducer is connected to the support member, and can also drive the support member to rotate.

[0030] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0031] In existing teaching recording and conference scenarios, cameras must not only record the entire audience but also provide close-up recordings of the speaker. Similarly, microphones must capture both the entire audience and the speaker.

[0032] In the relevant technical field, although panoramic cameras, omnidirectional microphones, zoom cameras and directional microphones can be integrated into audio and video recording equipment, the sound pickup effect of a single directional microphone in a fixed position is poor, resulting in poor clarity of the speaker's sound picked up by the directional microphone.

[0033] In the embodiment of the present application, the panoramic camera 112, omnidirectional microphone 113, zoom camera 122, and directional microphone 123 are integrated into the audio and video recording device 1. Once the audio and video recording system is installed, the panoramic camera 112, omnidirectional microphone 113, zoom camera 122, and directional microphone 123 can be installed. This reduces the difficulty of placement and improves installation convenience. Furthermore, multiple directional microphones 123 can be arranged around the perimeter of the daylight opening 121B, further optimizing the sound pickup effect of the directional microphones 123 and improving the clarity of the speaker's voice.

[0034] Please refer to Figure 1 and Figure 2 An embodiment of the present application provides an audio and video recording device 1, which includes a base component 11 and a pan-tilt head component 12.

[0035] The base assembly 11 includes a base body 111, a panoramic camera 112, and an omnidirectional microphone 113. The panoramic camera 112 and the omnidirectional microphone 113 are spaced apart from each other on the base body 111. The panoramic camera 112 and the omnidirectional microphone 113 can be installed by installing the base body 111, thereby reducing the installation steps of the panoramic camera 112 and the omnidirectional microphone 113 and improving the installation efficiency of the panoramic camera 112 and the omnidirectional microphone 113. It is understood that the material of the base body 111 can be metal or plastic. In other embodiments, the base body 111 can also be other materials. In the implementation of this application, there is no specific limitation on the material of the base body 111.

[0036] The pan / tilt assembly 12 includes a housing 121, a zoom camera 122, and a directional microphone 123. The zoom camera 122 and the directional microphone 123 are both connected to the housing 121. The housing 121 is connected to the base body 111 and is movable relative to the base body 111, allowing the zoom camera 122 and the directional microphone 123 to move relative to the base body 111. This allows the zoom camera 122 and the directional microphone 123 to be aimed at the speaker, allowing the zoom camera 122 to focus on the speaker and the directional microphone 123 to pick up the speaker's sound in a targeted manner, thereby improving the speaker's sound pickup effect. Furthermore, since the zoom camera 122 and the directional microphone 123 are both connected to the housing 121, allowing the zoom camera 122 and the directional microphone 123 to be installed along with the base body 111, improving the installation efficiency of the zoom camera 122 and the directional microphone 123.

[0037] Furthermore, since the zoom camera 122 and the directional microphone 123 are both disposed in the housing 121 , they can simultaneously follow the movement of the housing 121 , thereby improving the movement adjustment efficiency of the zoom camera 122 and the directional microphone 123 .

[0038] It is understood that the material of the housing 121 can be metal or plastic. In other embodiments, the housing 121 can also be made of other materials. In the implementation of this application, there is no specific limitation on the material of the housing 121.

[0039] In an embodiment of the present application, the panoramic camera 112, the omnidirectional microphone 113, the zoom camera 122 and the directional microphone 123 are integrated into the audio and video recording device 1. It is only necessary to complete the installation of the audio and video recording to achieve the installation of the panoramic camera 112, the omnidirectional microphone 113, the zoom camera 122 and the directional microphone 123, thereby reducing the difficulty of layout and improving the convenience of installation.

[0040] Please refer to Figure 1 and Figure 2 During a meeting or lecture, the panoramic camera 112 can capture a panoramic video of all participants, and the omnidirectional microphone 113 can collect the voices of all participants. When there is a speaker among the participants, the omnidirectional microphone 113 obtains the speaker's audio signal, and the controller can determine the speaker's spatial position based on the audio signal. The controller controls the housing 121 to move relative to the base body 111 so that the zoom camera 122 and the directional microphone 123 can be aimed at the speaker. The controller can control the zoom camera 122 to focus on the speaker and capture a close-up of the speaker. The directional microphone 123 can perform directionally picked up sound from the speaker, thereby improving the sound pickup effect of the speaker.

[0041] It is understood that the controller for determining the spatial position of the speaker based on the audio signal may be a first controller, and the controller for controlling the movement of the housing 121 relative to the base body 111 may be a second controller. The first controller and the second controller are electrically connected to facilitate signal exchange between the first and second controllers. It is understood that the first and second controllers may also be the same controller, and this is not specifically limited in the embodiments of the present application.

[0042] Please refer to Figure 1 and Figure 2 In one embodiment, the shell 121 has an installation cavity 121A, a light-collecting port 121B, and a sound pickup hole 121C. The light-collecting port 121B and the sound pickup hole 121C are both connected to the installation cavity 121A. The zoom camera 122 and the directional microphone 123 are both arranged in the installation cavity 121A, and the zoom camera 122 can shoot through the light-collecting port 121B. The directional microphone 123 is arranged corresponding to the sound pickup hole 121C so that the directional microphone 123 can obtain the speaker's voice through the sound pickup hole 121C.

[0043] It is understood that the connection methods for the zoom camera 122 and the housing 121 include, but are not limited to, screwing, snapping, or gluing. In other embodiments, the zoom camera 122 and the housing 121 may also be connected by other methods. In the embodiments of the present application, the connection method of the zoom camera 122 and the housing 121 is not specifically limited. For example, the zoom camera 122 is connected to a bracket, which is then connected to the housing 121 to achieve the connection between the zoom camera 122 and the housing 121. This also facilitates the use of the bracket to dissipate heat from the zoom camera 122, preventing the zoom camera 122 from overheating and reducing the probability of damage to the zoom camera 122. This can extend the service life of the zoom camera 122 and the audio and video recording device 1. The housing 121 also has an air outlet that communicates with the mounting cavity 121A, allowing hot air within the mounting cavity 121A to be discharged through the air outlet.

[0044] It is understandable that the connection method between the directional microphone 123 and the housing 121 includes but is not limited to screw connection, clip connection or adhesive connection. In other embodiments, the directional microphone 123 and the housing 121 can also be connected in other ways. In the embodiment of the present application, there is no specific limitation on the connection method between the directional microphone 123 and the housing 121. For example, the directional microphone 123 can be clamped between the connecting piece and the housing 121, and the connecting piece and the housing 121 are threadedly connected, which can also achieve the installation of the directional microphone 123. In the embodiment of the present application, no further details are given on this.

[0045] Please refer to Figure 1 and Figure 2 In one embodiment, there are multiple directional microphones 123, and the housing 121 has multiple sound pickup holes 121C. The directional microphones 123 are arranged in a one-to-one correspondence with the sound pickup holes 121C. By having multiple directional microphones 123 pick up the sound of the speaker at the same time, the sound pickup effect can be optimized and the clarity of the sound picked up from the speaker can be improved.

[0046] For example, the number of directional microphones 123 can be 4, 5, 6, 7, or 8. In this embodiment of the present application, there is no specific limitation on the number of directional microphones 123. Furthermore, the multiple directional microphones 123 can be arranged along a straight line, an arc, or a curve. In this embodiment of the present application, there is no specific limitation on the arrangement of the multiple directional microphones 123.

[0047] Please refer to Figure 1 and Figure 2In one embodiment, a plurality of sound pickup holes 121C are spaced around the side of the light opening 121B, so that a plurality of directional microphones 123 can be placed around the side of the light opening 121B, thereby further optimizing the sound pickup effect of the directional microphones 123 and improving the clarity of the sound pickup of the speaker.

[0048] Please refer to Figure 1 and Figure 3 In one embodiment, the pan-tilt assembly 12 further includes a ring-shaped circuit board 124, which is connected to the housing 121 and is disposed in the mounting cavity 121A. The ring-shaped circuit board 124 is disposed around the light opening 121B, and a plurality of directional microphones 123 are disposed at intervals on the ring-shaped circuit board 124, so that the directional microphones 123 are disposed around the light opening 121B, thereby optimizing the sound pickup effect of the directional microphones 123 and improving the clarity of the sound pickup of the speaker.

[0049] Please refer to Figure 1 and Figure 3 It can be understood that the directional microphone 123 can be welded to the annular circuit board 124 and electrically connected to the annular circuit board 124, and the connection method between the annular circuit board 124 and the shell 121 includes but is not limited to screw connection, clamping or gluing. In other embodiments, the annular circuit board 124 and the shell 121 can also be connected in other ways. In the embodiment of the present application, there is no specific limitation on the connection method between the annular circuit board 124 and the shell 121. For example, the annular circuit board 124 is clamped between the connecting piece and the shell 121, and the connecting piece is threadedly connected to the shell 121, which can also realize the installation of the annular circuit board 124. In the embodiment of the present application, no further details are given on this.

[0050] Please refer to Figure 1 In one embodiment, there are multiple omnidirectional microphones 113, and two adjacent omnidirectional microphones 113 are arranged at intervals. Using multiple omnidirectional microphones 113 can improve the recording effect of the entire field sound. Compared with only one omnidirectional microphone 113, the controller can determine the spatial position of the speaker through multiple omnidirectional microphones 113, thereby facilitating the controller to control the movement of the shell 121 so that the zoom camera 122 and the directional microphone 123 are aimed at the speaker, thereby improving the positioning accuracy of the speaker, improving the aiming accuracy of the zoom camera 122 and the directional microphone 123, and improving the accuracy of the zoom camera 122 in obtaining close-up images of the speaker and the directional microphone 123 in picking up the speaker's directional sound.

[0051] For example, the number of omnidirectional microphones 113 can be 4, 5, 6, 7, or 8. In the embodiments of the present application, there is no specific limitation on the number of omnidirectional microphones 113. It is understood that the multiple omnidirectional microphones 113 can be arranged along a straight line, an arc, or a curve. In the embodiments of the present application, there is no specific limitation on the arrangement of the multiple omnidirectional microphones 113.

[0052] Please refer to Figure 1 In one embodiment, the omnidirectional microphone 113 and the panoramic camera 112 are arranged on the same side of the base body 111 to improve the synchronization between the audio signal obtained by the omnidirectional microphone 113 and the video signal obtained by the panoramic camera 112, thereby improving the audio and video recording effect.

[0053] It is understandable that the omnidirectional microphone 113 may also be provided on other surfaces of the base body 111 to increase the sound pickup range of the omnidirectional microphone 113 and to improve the accuracy of determining the speaker's position.

[0054] Please refer to Figure 1 In one embodiment, the pan / tilt assembly 12 further includes a support member 125 rotatably connected to the base body 111 and capable of rotating relative to the base body 111 in a first direction X. The housing 121 is rotatably connected to the support member 125 and capable of rotating relative to the support member 125 in a second direction Y, wherein the first direction X is perpendicular to the second direction Y. By controlling the base body 111 to rotate in the first direction X and the housing 121 to rotate in the second direction Y, the zoom camera 122 and the directional microphone 123 can move on the surface of the spherical shell, thereby increasing the range of motion of the zoom camera 122 and the directional microphone 123. This ensures that both the zoom camera 122 and the directional microphone 123 can be aimed at the speaker, thereby improving the clarity of the zoom camera 122's image of the speaker and the accuracy of the directional microphone 123's directional pickup of the speaker.

[0055] Please refer to Figure 1 In one embodiment, the support member 125 has an avoidance groove 125A on the side away from the base body 111, and the shell 121 is rotatably connected to the groove wall of the avoidance groove 125A, which can reduce the space occupied by the shell 121 around the audio and video recording device 1, so that the overall volume of the audio and video recording device 1 is smaller, thereby facilitating the production and transportation of the audio and video recording device 1.

[0056] Please refer to Figure 1 and Figure 2In one embodiment, the audio and video recording device 1 also includes a first driving device 13, which is arranged on the base body 111, and the output shaft of the first driving device 13 is connected to the support member 125, so that the support member 125 can rotate around the first direction X, so that the zoom camera 122 and the directional microphone 123 can both rotate around the first direction X.

[0057] For example, the first drive device 13 may include a motor connected to the base body 111, and the output shaft of the motor is connected to the support member 125 to drive the support member 125 to rotate. In other embodiments, the first drive device 13 may also include a motor and a reducer connected to the motor, and the output shaft of the reducer is connected to the support member 125 to also drive the support member 125 to rotate. In the embodiments of the present application, the specific form of the first drive device 13 is not limited.

[0058] Please refer to Figure 1 and Figure 2 In one embodiment, the audio and video recording device 1 also includes a second driving device 14, which is arranged on the support member 125, and the output shaft of the second driving device 14 is rotatably connected to the shell 121, so that the shell 121 can rotate around the second direction Y, so that the zoom camera 122 and the directional microphone 123 can both rotate around the second direction Y.

[0059] For example, the second drive device 14 may include a motor connected to the support member 125, and the output shaft of the motor is connected to the housing 121 to drive the housing 121 to rotate. In other embodiments, the second drive device 14 may also include a motor and a reducer connected to the motor, and the output shaft of the reducer is connected to the housing 121 to also drive the housing 121 to rotate. In the embodiments of the present application, the specific form of the second drive device 14 is not limited.
