[0034] refer to Figures 1 to 4The setting of the adjustment component can facilitate the adjustment of the microphone body 3 to the specified direction, so that the voice command of the specified direction can be received, thereby improving the accuracy of receiving the voice command of the specified direction and reducing the effect of receiving surrounding sounds.

[0035] The adjusting assembly includes a mounting block 5 fixed on the upper surface of the turntable 4, and an electric push rod 6 hinged to the mounting block 5 and the bottom surface of the adjusting cylinder 2. The electric push rod 6 is used to promote the movement of the adjusting cylinder 2. The adjusting assembly also includes a limit assembly connected to the adjusting cylinder 2.

[0036] By setting up the adjustment component, it is convenient to push the adjustment cylinder 2 through the electric push rod 6 to perform tilting movement under the action of the limit component, so that the adjustment cylinder 2 can drive the microphone body 3 to adjust the angle in the box 1, so that the microphone body 3 can be adjusted to the specified direction, so as to receive voice commands or sound information at the specified direction.

[0037] The limiting assembly includes an annular sliding groove 7 formed on the inner wall of the box body 1 , and a limiting sliding rod 8 fixed on the outer surface of the adjusting cylinder 2 and slidably connected to the annular sliding groove 7 . The limiting sliding rod 8 and the electric push rod 6 are arranged in a vertical position.

[0038] By setting a limit component, the adjusting cylinder 2 can be limited and tilted when the electric push rod 6 pushes the adjusting cylinder 2 to move, and can cooperate with the rotating component to rotate the adjusting cylinder 2, thereby facilitating the designated adjustment of various directions, thereby greatly improving the accurate reception of voice commands.

[0039] The outer surface of the box body 1 is fixedly connected with mounting plates 17 in a ring array, and the mounting plates 17 are used to mount the box body 1 by means of bolts.

[0041] A sound insulation component and a rotating component connected to the turntable 4 are arranged inside the box 1 , and the rotating component is used to drive the turntable 4 to rotate.

[0042] refer to Figures 1 to 4 The setting of the sound insulation component can facilitate noise reduction and noise blocking of the microphone body 3 after the angle is adjusted, and the setting of the rotating component can facilitate the rotation of the adjustment component and the sound insulation component, thereby enabling rotational adjustment, greatly improving the application range of the overall device.

[0054] The working principle of the present invention is as follows:

[0055] Device installation:

[0056] The entire device is installed at a specific location in the vehicle, such as the central control area, by means of the mounting plate 17 and bolts, to ensure that the device is stable and easy to operate.

[0057] Angle adjustment:

[0058] When it is necessary to receive a voice command in a designated direction, the electric push rod 6 is started.

[0059] The output end of the electric push rod 6 pushes the adjusting cylinder 2, and under the limiting action of the annular sliding groove 7 and the limiting sliding rod 8, the adjusting cylinder 2 performs a tilting movement.

[0060] The adjustment cylinder 2 drives the microphone body 3 to shift its angle until it is aligned with a specified position.

[0061] Sound insulation adjustment:

[0062] When the adjusting cylinder 2 tilts, the sound insulating cylinder 9 moves along with it.

[0063] The sound insulation tube 9 moves under the limiting and guiding action of the curved guide plate 12 through the connecting rod 10 and the roller 11.

[0064] The roller 11 slides on the curved guide plate 12 to push the sound insulation tube 9 to move upward in the adjustment cylinder 2 until it extends out of the microphone body 3.

[0065] The sound insulation tube 9 and the sound insulation cotton 13 inside jointly reduce and block the surrounding sounds, thereby reducing the interference of non-target direction sounds on the microphone body 3.

[0066] Rotation adjustment:

[0067] If the position of the microphone body 3 needs to be further adjusted, the servo motor 16 can be started.

[0068] The output end of the servo motor 16 drives the turntable 4 to rotate.

[0069] The turntable 4 is slidably connected to the annular groove on the inner wall of the housing 1 via a fixing ring 15 to ensure stability and smoothness during rotation.

[0070] The rotation of the turntable 4 drives the adjustment cylinder 2, the microphone body 3 and the sound insulation component to rotate together, thereby achieving all-round adjustment.

[0071] Voice command reception:

[0072] After being adjusted to a designated position and the sound insulation effect is turned on, the microphone body 3 can accurately receive voice commands from that position.

[0073] The voice command is transmitted to the in-vehicle voice assistant system through the microphone body 3 for processing and execution.

[0074] Reset operation:

[0075] When it is no longer necessary to receive voice commands in a specified direction, the microphone body 3 and the sound insulation assembly can be reset to the initial position by operating the electric push rod 6 and the servo motor 16 in reverse.

[0076] At this time, the sound insulation tube 9 descends, releasing the sound insulation effect on the microphone body 3, so that the microphone body 3 can recover the ability to receive all-round voice commands in the car.
