Mobile vehicle-mounted microphone

Abstract

The invention relates to a mobile vehicle-mounted microphone. The mobile vehicle-mounted microphone comprises a guide rail, a sliding block, a motor and a microphone module, the guide rail is installed on a ceiling of an automobile, the microphone module is connected with the guide rail through the sliding block, and the motor is installed on the guide rail and used for driving the sliding block to slide along the guide rail. Directional movement of the microphone is realized, it is ensured that the microphone can move to a position closest to a sounder, the dependence of a traditional fixed installation mode on an arrangement space is solved, the voice recognition stability of the microphone can be improved, the investment of algorithms and the number of microphones is reduced, and the development strength and cost of software are reduced.

Description

technical field [0001] The invention relates to a vehicle-mounted microphone, in particular to a mobile vehicle-mounted microphone. Background technique [0002] At present, microphones have basically become standard equipment on passenger cars. Most of the existing microphones are installed on the dome lights, rearview mirrors, A-pillars, steering wheels, sun visors, etc. of the car. The microphone serves as the entrance of the voice recognition function. The quality of the sound signal collected is strongly related to the external environment between the sound source and the microphone, especially the position and distance between the speaker and the microphone, which are related to the best performance of the microphone for sound signal collection. Angle, sensitivity and other parameters. Therefore, the current microphone installed at a fixed position is restricted by the layout space of the whole vehicle, and it is difficult to achieve the best sound collection distance...

AI Technical Summary

Problems solved by technology

Therefore, the current microphone installed at a fixed position is restricted by the layout space of the whole vehicle, and it is difficult to achieve the best sound collection distance and angle. More than 3 microphones will increase the cost of materials. In addition, complex algorithms and multi-microphone arrays are needed to make up for the functional effect, which is not ideal in terms of development efforts and costs. The key point is that the identification is often invalid or misidentified. Experience, lose the original intention of voice recognition to achieve simple and fast operation
