Bone conduction sound pickup

Abstract

The invention relates to the technical field of sound pickups, in particular to a bone conduction sound pickup, which is fixed on the head of a human body through a head-mounted bracket, and comprises a buzzing piece which fits the protruding part of the human skull; a frequency selection module which is fixedly arranged on the head-mounted bracket, wherein the input end of the frequency selection module is electrically connected with the input end of the buzzer; an oscillation pickup module which is fixedly arranged on the head-mounted bracket, and the input end of the oscillation pickup module is electrically connected with the output end of the frequency selection module; and a sound source frequency conversion module which is fixedly arranged on the head-mounted bracket and is provided with an external data interface, and the output end of the oscillation pickup module is connected with the input port of the sound source frequency conversion module. According to the invention, the buzzing piece is used for directly collecting the sound generated by the wearer without collecting the external environmental noise, so that the noise reduction characteristic is realized, the environmental noise is physically and completely solved, and the noise reduction problem is not required to be solved by an algorithm.

Description

technical field [0001] The invention relates to the technical field of sound pickups, in particular to a bone conduction sound pickup. Background technique [0002] In real life, a microphone is often used as a component for collecting sound signals, and the sound signal can be obtained by collecting the user's voice, but the conventional microphone has weak anti-interference ability when collecting sound signals, and cannot clearly Collecting the voice of the user causes noise in the collected sound signal, which reduces the quality and efficiency of collecting the sound signal. Therefore, the microphone in the prior art method has the problem of noise in the collected sound signal. Contents of the invention [0003] The present invention provides a bone conduction pickup, which directly collects the wearer's own voice through the buzzer piece pressed against the protruding part of the wearer's skull, without collecting external environmental noise, so it has the charact...

[0002] In real life, a microphone is often used as a component for collecting sound signals, and the sound signal can be obtained by collecting the user's voice, but the conventional microphone has weak anti-interference ability when collecting sound signals, and cannot clearly Collecting the voice of the user leads to noise in the collected sound signal, which reduces the quality and efficiency of sound signal collection

Therefore, the microphone in the prior art method has the problem that the collected sound signal has noise
