Device for adjusting car microphone

Abstract

The invention provides a device for adjusting a car microphone, belonging to the technical field of car parts. The invention solves the problem that the existing car microphone can not be adjusted. The device for adjusting the car microphone is characterized in that the microphone is provided with a shell and a support for installing the microphone; the adjusting device is arranged between the shell and the support, and is composed of a motor control unit, a drive motor and a button; the drive motor and the button are connected with the motor control unit, the shell is universally connected with the support, and the drive motor is arranged between the shell and the support; and the motor control unit controls the rotation of the drive motor according to signals input by the button so as to adjust the angle of the shell of the microphone relative to the support. By using the device provided by the invention, the orientation of the car microphone can be adjusted so as to ensure the best speech input of users.

Description

technical field [0001] The invention belongs to the technical field of auto parts and relates to a vehicle-mounted microphone, in particular to an adjustment device for the vehicle-mounted microphone. Background technique [0002] In order to drive safety and comfort, a Bluetooth car hands-free system is generally installed in the car at present. Its main function is to automatically identify the mobile phone. It can be connected to the mobile phone without a cable or a phone bracket, and the user does not need to touch the mobile phone. Keep your hands on the steering wheel to control your phone and use voice commands to answer or make calls. Users can make calls through the car's microphone or Bluetooth wireless headset. If you choose a Bluetooth wireless headset to make a call, as long as the headset is turned on, you can press the answer button when there is an incoming call. Mute, voice transmission through the speaker and microphone of the audio system. [0003] As ...

AI Technical Summary

Problems solved by technology

[0003] As a commonly used audio input device, car microphones generally have the problems of poor dustproof effect and low anti-interference performance. Therefore, people have made various designs and improvements to car microphones, and some have applied for patents, such as Chinese patent documents Disclosed is a vehicle-mounted hands-free microphone [application number: 200520142875.1; authorized announcement number: CN2854991Y], which includes a housing, a built-in electret, a circuit board and its output line, and an omentum is installed on the plane receiving the sound of the housing. The omentum is fixed on the end face of the shell wall; there is a cavity directly in front of the electret, the board surface of the circuit board is perpendicular to the plane on which the electret receives sound, and the output line is parallel or parallel to the plane on which the electret receives sound. Vertical; shielded cover inside housing and omentum

[0004] The above-mentioned vehicle-mounted microphone adopts omentum and shielding cover at the same time, and its sound signal transmission, reception and response, dustproof and anti-interference performance are all good, but its position is arranged with the driver first, and the microphone is directed to the driver. After the microphone is installed, the angle is fixed. When the driver’s head turns a certain angle, the incident angle of the sound wave changes, which affects the voice quality of the microphone. At the same time, if other passengers in the car need a hands-free microphone , the above-mentioned hands-free microphones simply cannot meet this requirement
