Description

Technical Field

[0002] A microphone, also known as a handheld microphone, is an electroacoustic device. It is a microphone and a transducer for sound-to-electricity conversion. The vibration of sound is transmitted to the diaphragm of the microphone, pushing the magnet inside to form a changing current. The changing current is sent to the sound processing circuit behind it for amplification. The sound waves act on the electroacoustic elements to generate voltage, which is then converted into electrical energy. It can be used in various sound amplification equipment.

[0003] When existing microphones are used for a long time, the vibration of the diaphragm will drive the coil to vibrate. In the process of the coil generating induced current in the magnetic field, the magnet will resonate to a certain extent, which will seriously affect the sound quality of the microphone and increase the noise in the microphone, thus affecting people's use.
