Problems solved by technology

This inhalation sound will affect the effect of broadcasting, singing, and performance
[0003] At present, post-processing methods are generally used to eliminate the inhalation sound made by singers recording songs and musicians playing instruments, but it is still not perfect; and the inhalation sound made by musicians, singers or announcers during live performances or broadcasting Since the sound cannot be eliminated in real time technically, the position of the microphone is generally controlled by the performer. When inhaling, the mouth position should be as far away from the microphone as possible to reduce the inhalation sound, but the effect is still not ideal, and it is difficult for the performance. cause inconvenience

Embodiment Construction

[0035] When the announcer broadcasts, the singer sings, and the musician plays the instrument, the chest cavity rises and falls along with the breathing synchronization. With the chest cavity rising and falling, the chest circumference (chest circumference) changes accordingly. According to calculations, when the general adult sings or plays, the change of chest circumference caused by breathing is about 10 cm, which is very obvious.

[0036] The breath-synchronized inspiratory sound shielding method provided by the present invention is designed to capture the physiological characteristics that the thoracic circumference continues to increase when a person is inhaling, and the thoracic circumference continues to decrease when exhaling (talking, playing, singing). Achieved.

[0037] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

Abstract

The embodiment of the invention relates to a breathing synchronized inhaling sound shielding method and device and a microphone system. The breathing synchronized inhaling sound shielding method comprises the following steps: monitoring the change of chest circumference of a user and generating an analogue voltage signal according to the change of the chest circumference; when the chest circumference of the user is increased, outputting a first analogue voltage signal; when the chest circumference of the user is decreased, outputting a second analogue voltage signal, wherein electrical levels of the first analogue voltage signal and the second analogue voltage signal are opposite, carrying out amplification processing on the analogue voltage signals; carrying out non-logic processing on the signals subjected to the amplification processing to generate a switching signal; and transmitting the switching signal to a microphone, and switching on or switching off the output of an audio signal, which is obtained by the microphone, according to the switching signal by the microphone.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a breath-synchronized suction sound shielding method and device and a microphone system. Background technique [0002] When we listen to announcers broadcasting, singers singing, musicians playing flute or flute and other musical instruments, we can usually hear the inhalation sound of announcers, singers, and musicians when they take a breath. This inhalation sound will affect the effect of broadcasting, singing and playing. [0003] At present, post-processing methods are generally used to eliminate the inhalation sound made by singers recording songs and musicians playing instruments, but it is still not perfect; and the inhalation sound made by musicians, singers or announcers during live performances or broadcasting Since the sound cannot be eliminated in real time technically, the position of the microphone is generally controlled by the performer. When inhaling, ...
