Voice-tracking microphone and control method of voice-tracking microphone

Abstract

The invention provides a voice-tracking microphone and a control method of the voice-tracking microphone. The voice-tracking microphone is characterized by comprising a body, a voice sensor set, a control circuit and a drive device. The body comprises a movable shaft, a base and a microphone body. The voice sensor set is used for picking up a corresponding upper voice signal, a corresponding lower voice signal, a corresponding left voice signal and a corresponding right voice signal according to a voice source. The control circuit comprises an A / D converter, a comparison circuit and a drive circuit. The drive device comprises a height adjustment mechanism and a direction adjustment mechanism, wherein the height adjustment mechanism is used for adjusting the height of the microphone body, the direction adjustment mechanism is used for adjusting the direction of the microphone body, the microphone body is adjusted to be higher when an upper volume value is larger than a lower volume value, the microphone body is adjusted to be lower when the upper volume value is smaller than the lower volume value, the microphone body is rotated leftward when a left volume value is larger than a right volume value, and the microphone body is rotated rightward when the right volume value is larger than the left volume value. According to the voice-tracking microphone, the voice sensor set adjusts the height and the direction of the microphone body according the position of the voice source so that voice tracking can be realized, and great convenience is brought to a user.

Description

technical field [0001] The invention relates to a microphone, in particular to a sound tracking microphone capable of adjusting height and direction according to the position of a sound source and a control method for the sound tracking microphone. Background technique [0002] Microphones, also known as microphones, are electro-acoustic equipment commonly used in various conferences, events, and stage performances. Microphones can be divided into two types: handheld and stand-type, the latter is to place the microphone on the microphone stand. At present, on the stage, performers or speakers often encounter situations where the height and direction of the microphone are not suitable. It is necessary to manually adjust the height and direction to suit different users. The operation is cumbersome, which is both troublesome and affects the performance. [0003] In view of the fact that the above-mentioned microphones cannot meet the needs of different users for the height and...

AI Technical Summary

Problems solved by technology

At present, on the stage, performers or speakers often encounter the situation that the height and direction of the microphone are not suitable, and the height and direction need to be adjusted manually to suit different users. The operation is cumbersome, which is troublesome and affects the performance effect.

[0003] In view of the fact that the above-mentioned microphones cannot meet the needs of different users for the height and direction of the microphone, the prior art lacks a tracking microphone that can automatically adjust the height and direction of the microphone according to the position of the sound source.
