Abstract
Description
Technical Field
[0001] The utility model specifically relates to a camera integrating sound source localization, belonging to the technical field of cameras. Background Art
[0002] A camera can take pictures of images and then store the captured video images in a server through a data cable. However, most traditional cameras are simply fixed to the external structure and cannot rotate by themselves. In some scenarios, it is necessary for the camera to adjust and rotate a certain angle by itself to capture a specified image. However, using external manual control is too complex. Therefore, people have found that the sound source can be used as the positioning direction of the camera, enabling the camera to have "vision" and "hearing", and thus having a larger shooting range and greater flexibility in the shooting space.
[0003] For example, in a Chinese invention patent document titled "A Monitoring Camera Device with Double Heads that Can Be Telescoped and Rotated", with the publication number CN109379515A, it includes a camera housing, a main monitoring camera, and an auxiliary monitoring device. A main monitoring camera is fixedly installed on the right side of the camera housing, and a slideway is opened at the bottom of the camera housing, and an auxiliary monitoring device is movably installed in the slideway.
[0004] The above document uses a double-head structure to achieve a backup effect, and can adjust the monitoring angle of the auxiliary camera through the cooperation of a rotating motor and an electromagnetic telescopic rod, ensuring a larger monitoring range for the auxiliary camera.
[0005] However, the camera in the above document, like many traditional cameras, requires additional precise rotation control of the camera. The function of the camera itself is single, and the rotation adjustment range of the rotating motor is limited, resulting in a small improvement in the effect of expanding the shooting range of the camera, and the adjustment and use are not flexible. Summary of the Utility Model
[0006] The purpose of the utility model is to provide a camera integrating sound source localization for the deficiencies of the prior art, which can achieve the effect of flexibly adjusting the shooting angle according to the sound source, with more flexible use and a wide shooting range.
[0007] A camera integrating sound source localization includes an assembly plate fixed to an external support. A bracket plate is provided below the assembly plate. A horizontal rotation motor for controlling the horizontal rotation of the bracket plate is fixed to the bottom of the assembly plate. A tray is rotatably installed between the bracket plates. A vertical rotation motor for controlling the rotation of the tray is installed on the outer wall of the bracket plate. A camera main body is snap-fitted and installed on the tray. The coordinated operation of the horizontal rotation motor and the vertical rotation motor can perform operations of turning the tray up and down and horizontally rotating it. A snap-fitting component is provided on the upper surface of the tray. The snap-fitting component can facilitate the assembly of the camera main body by personnel and can reduce mechanical vibration. The camera main body is fixedly connected to the tray through the snap-fitting component. A positioning component is fixed to the bottom of the tray through a connecting column. The positioning component can perform angular position positioning by receiving sound sources from different directions. When in use, an external control processing module is also required to receive and process the audio information received by the sound source probe. After comparison and processing by the control processing module, the vertical rotation motor and the horizontal rotation motor are then controlled to perform corresponding operations. A power connector is provided on one side of the tray through a power cord.
[0008] The positioning component includes a wheel-shaped component located below the tray. The outer wall of the front lower part of the wheel-shaped component is arc-shaped. Side extension components are fixed to the side walls of the wheel-shaped component. The extending ends of the side extension components extend respectively to the left and right sides of the wheel-shaped component. Vertical sound source probes are vertically provided on the side walls of the wheel-shaped component. Horizontal sound source probes are provided on the side walls of the side extension components. This can facilitate the reception of sound sources from all directions.
[0009] The bottom end of the connecting column is fixed to the upper surface of the side extension component. An auxiliary plate is fixed to the extending end of the side extension component. An auxiliary support column fixedly connected to the bottom of the tray is fixed on the auxiliary plate. The auxiliary support column can increase the stability of the tray.
[0010] A reference sound source probe is fixed to the rear side wall of the wheel-shaped component. Sound receiving outer cylinders are provided outside the vertical sound source probes, horizontal sound source probes, and the reference sound source probe. The sound receiving outer cylinders are used to reduce sound interference in redundant directions.
[0011] A first horizontal notch is opened on the sound receiving outer cylinder outside the vertical sound source probe. A second vertical notch is opened on the sound receiving outer cylinder outside the horizontal sound source probe. An arc-shaped sound receiving plate is provided behind the wheel-shaped component. A sound insulation layer is provided on the rear side wall of the arc-shaped sound receiving plate. A sound transmission hole is opened on the arc-shaped sound receiving plate on the side corresponding to the reference sound source probe. The coverage angle of the arc-shaped sound receiving plate for the wheel-shaped component is less than 180 degrees. Since the vertical sound source probe and the horizontal sound source probe work independently, opening the first horizontal notch and the second vertical notch can increase the corresponding sound receiving range, making it more sensitive during position adjustment.
[0012] The positioning assembly includes a clamping block located on the upper surface of the pallet. The first end outer wall of the clamping block is rotatably mounted on the pallet through a rotating plate. A locking plate is fixed to the second end of the clamping block. A locking hole is provided on the locking plate. The inner wall of the clamping block is arc-shaped, and an inlay plate is fixed on the inner wall of the clamping block. In order to reduce the transmission of vibration, a rubber layer can be provided on the inlay plate and the inner wall of the clamping block.
[0013] The clamping blocks jointly enclose a combination with a closed center. A fixing column for fixing the position of the rotating plate is fixed on the pallet. An end cover plate is provided at the top of the fixing column. A bottom block that supports the bottom of the locking hole is fixed on the pallet. A threaded hole penetrating the pallet is provided on the bottom block. A locking bolt for fixing the locking plate is installed in the threaded hole by threading. The position of a pair of clamping blocks can be fixed at one time by using the locking bolt, which can speed up the installation and disassembly of the camera body.
[0014] A clamping groove is provided on the pallet corresponding to the enclosed clamping blocks. A clamping column is fixed to the bottom of the camera body.

A clamping block corresponding to the clamping groove is fixed to the bottom end of the clamping column. A space is left between the bottom end of the clamping column and the surface of the pallet, and a space is left between the bottom end of the clamping block and the bottom of the clamping groove.
[0015] Technical effects and advantages of the present utility model: This camera can adjust the angle according to the sound source. Moreover, compared with traditional cameras, it has a larger positioning range and higher accuracy, and can reduce the use of sound source probes, which can save manufacturing costs. The coordinated operation of the horizontal rotation motor and the vertical rotation motor can perform operations of turning the pallet up and down and horizontally rotating. When a sound source emits sound anywhere, the corresponding vertical sound source probe and horizontal sound source probe are triggered, and then the volume sizes of each sound source probe are compared to obtain the specific angle direction. The sound emitted behind the camera body can be acquired by the reference sound source probe, and the rotation of the pallet is controlled after comprehensive comparison, so that the position and angle adjustment of the camera body can be more accurate, and the acquired sound source range is larger.

[0029] In the present utility model, with the shooting direction of the shooting main body 3 as the front, when facing the shooting main body 3, left and right are distinguished. This camera can adjust the angle according to the sound source, and compared with traditional cameras, it has a larger positioning range and higher accuracy, and can reduce the use of sound source probes, thus saving manufacturing costs. When in use, the coordinated operation of the horizontal rotation motor 102 and the vertical rotation motor 103 can perform the operations of turning the support plate 2 up and down and horizontally rotating.
