An object of the utility model is to provide a vibrating part for speaker possesses simple structure, and vibrating part's quality is light, can improve speaker db value, can absorb the noise that produces when the speaker resonates simultaneously, and the sound production effect is good, and the user experiences when using feels good advantage, has solved the problem that above-mentioned technical background proposed.

In order to achieve the above object, the utility model provides a following technical scheme: a vibrating member for a loudspeaker, comprising: the loudspeaker body and set up drum paper and sound membrane on the loudspeaker body, drum paper and sound membrane interval set up, and drum paper and sound membrane all include substrate layer and foaming layer, the substrate layer include the first surface and with the second surface that the first surface is relative, the coating of foaming layer is on the first surface, and the thickness value of foaming layer is between 0.02mm-3 mm.

Preferably, the substrate layer is a fabric layer, and the thickness value of the fabric layer is between 0.03mm and 0.5 mm.

Preferably, the base material layer is a polyester film, and the thickness value of the polyester film is between 0.018mm and 2 mm.

Preferably, the base material layer is a metal film, and the thickness value of the metal film is between 0.02mm and 2 mm.

Preferably, the foaming layer is a foaming glue layer.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the utility model provides a drum paper and sound membrane constitute by substrate layer and foaming layer, with the thickness of foaming layer coating in order to increase vibrating part on the substrate layer, can absorb the noise that produces when drum paper and sound membrane resonate, for the substrate layer coating glue layer and the laminating foaming layer that use traditional thickness, the quality is lighter, can effectively increase the sensitivity of speaker vibrating part, and then improves the db value of speaker, the effectual problem that the db value of having solved the speaker descends.

2. The utility model provides a foaming layer is the foaming glue film, and this foaming glue film's inside is comparatively soft, can change the high frequency that causes because of the hardness of substrate itself for sound is comparatively soft in the performance, has increased the experience sense when the user uses.

3. The utility model discloses a direct coating foaming layer on the first surface of substrate layer can effectually prevent that the substrate layer from producing static, has saved the cost that the substrate layer antistatic treatment, and the practicality is strong, is worth promoting.
