Title: DIAPHRAGM
Abstract:
Disclosed in the present invention is a diaphragm, comprising a middle part, a folding ring part, and an edge part connected in sequence from inside to outside, the folding ring part comprising at least two folding rings, the width of the at least two folding rings being the same, and adjacent folding rings being tangential and facing in opposite directions. The equal-width folding ring structure greatly reduces asymmetry in the direction of vibration of the folding rings, such that the rigidity of the vibrating system is similar in the positive direction and the negative direction, thereby reducing the non-linear properties of the structure and facilitating reduction of the THD of a transducer.
