Description

A diaphragm with enhanced mid-bass and zero noise

technical field

The utility model relates to the technical field of electroacoustic products, in particular to a vibrating membrane with enhanced middle and low frequency ranges and zero noise.

Background technique

The diaphragm plays a vital role in the sound reproduction of the speaker. It determines the conversion quality of the speaker from force to sound, and determines the power of the speaker and the quality of the playback sound. The material of the diaphragm requires low density and rigidity. Good and moderate damping are three basic conditions. The pattern structure of the diaphragm can be roughly divided into two types, one is the sunflower shape, and the other is the flat film shape. The full-band earphones generally use the sunflower pattern, and the patterns change. It is mainly the strength of the diaphragm, so as to improve the effect of splitting vibration.
