Problems solved by technology

[0002] The microphone core is an energy conversion device that converts sound signals into electrical signals. It is the input terminal of sound equipment. The condenser microphone core is an important component of the microphone. Its appearance is generally cylindrical, the shell is closed, and the diaphragm is installed inside. Gaskets, back plates, acoustic chambers, electronic components, tuning materials, welding parts, etc.; due to the relatively simple structure of the existing common capacitor microphone core, there is only one sound channel, which will cause excessive vibration of the diaphragm, poor sound quality, and low sensitivity. It is not easy to adjust and it is easy to produce some noise, which affects the quality of sound recording

Abstract

Disclosed is a capacitance microphone core with a shunting channel. A front cavity and a vent hole are connected through the shunting channel composed of a front sound inlet hole, the front cavity, an air guide structural member, a side cavity and the vent hole which are connected in sequence, redundant sound waves in the front cavity are shunted through the sound shunting channel, the volume and the flow speed of sound airflow flowing through a vibrating diaphragm are reduced, and the sound airflow passing through the vibrating diaphragm is kept in a relatively constant range with small fluctuation, so that the vibration between the vibrating diaphragm and a back polar plate is relatively constant, generated electric signals are relatively stable, the sound quality effect is improved, noise is avoided, and the pickup distance, the sound sensitivity and the sound definition of the sound are improved.

Description

technical field [0001] The invention relates to the technical field of microphone accessories, in particular to a capacitor microphone core with a shunt channel. Background technique [0002] The microphone core is an energy conversion device that converts sound signals into electrical signals. It is the input terminal of sound equipment. The condenser microphone core is an important component of the microphone. Its appearance is generally cylindrical, with a closed shell, and a diaphragm, Gaskets, back plates, acoustic chambers, electronic components, tuning materials, welding parts, etc.; due to the relatively simple structure of the existing common condenser microphone core, there is only one sound channel, which will cause excessive vibration of the diaphragm, poor sound quality, and low sensitivity. It is not easy to adjust and it is easy to produce some noise, which affects the quality of sound recording. [0003] Therefore, existing microphones have the above-mention...
