摘要

A speaker having a support structure having a bracket, and a vibration structure having a bend ring. The bend ring comprises an arc portion and an outer brim connected to the bracket. The outer brim of the bend ring extends downwardly to abut and connect to an outer brim of the top of the bracket, and the outer brim of the bend ring does not exceed the outermost end of the arc portion in the radial direction. The effective vibration area of a speaker is increased by using the above structure, so that the sensitivity of the speaker is improved.

TECHNICAL FIELD

The disclosure relates to a speaker, more particularly, to a speaker with an improved bend ring structure.

BACKGROUND ART

At present, with the increasing popularity of traditional sound boxes and smart sound boxes in the market, consumers are increasingly demanding sound quality. A speaker is a core component in a sound box, and its specific design requirements may include one or more of the following aspects: (1) a speaker can withstand high power; (2) a speaker has a lower resonant frequency; (3) a speaker has a very high sensitivity; (4) the size of a speaker is as small as possible; and (5) a speaker has low distortion.

The effective vibration area of a speaker is an important factor affecting the sensitivity of the speaker. On the one hand, the market needs a lighter, thinner and smaller speaker, and on the other hand, a smaller volume of a speaker may reduce the effective vibration area, so that a decrease in the sensitivity of a speaker may be caused.

Therefore, it is desirable to provide a speaker that has as large an effective vibration area as possible under a certain outer diameter limit.

SUMMARY OF THE INVENTION

The present disclosure provides a speaker having as large an effective vibration area as possible.
