Abstract

A vibration member is provided in the present disclosure. The vibration member includes a vibration body and a periphery connected with the vibration body, and the periphery includes a first connecting portion, a second connecting portion and a middle connecting portion. The first connecting portion is configured for fixing the vibration body. The second connecting portion is configured for fixing the vibration body. The middle connecting portion is configured for connecting the first connecting portion with the second connecting portion, and the middle connecting portion protrudes in a direction perpendicular to a vibrating direction of the vibration body. A sound generating device using the vibration member also is provided.

First claim

What is claimed is:

1 . A vibration member, comprising:
a vibration body; and a periphery connected with the vibration body, wherein the periphery comprises:
a first connecting portion, for fixing the vibration body;
a second connecting portion for fixing the vibration body, and
a middle connecting portion for connecting the first connecting portion with the second connecting portion, the middle connecting portion protruding in a direction perpendicular to a vibrating direction of the vibration body.

2 . The vibration member of claim 1 , wherein the middle connecting portion comprises a first arc surface connected with the first connecting portion, a second arc surface connected with the second connecting portion, and a middle portion configured for connecting the first arc surface with the second arc surface.

3 . The vibration member of claim 2 , wherein the first arc surface has a curvature radius same to that of the second arc surface.

4 . The vibration member of claim 2 , wherein the middle portion has a planar surface.

5 . The vibration member of claim 2 , wherein the middle portion has an arc surface having a curvature radius greater than that of the first arc surface and/or the second arc surface.

6 . The vibration member of claim 1 , wherein the vibration body has an upper surface and a lower surface opposite to the upper surface, the second connecting portion is connected with the upper surface or the lower surface.

7 . A sound generating device, comprising
a housing, and a vibration member disposed in the housing and connected with the housing, the vibration member comprising: a vibration body; and a periphery connected with the vibration body, wherein the periphery comprises:
a first connecting portion, for fixing the vibration body;
a second connecting portion for fixing the vibration body, and
a middle connecting portion for connecting the first connecting portion with the second connecting portion, the middle connecting portion protruding in a direction perpendicular to a vibrating direction of the vibration body.

8 . The sound generating device of claim 7 , wherein the housing comprises a shell having an end surface, and a cover covering the end surface of the shell, and the first connecting portion of the vibration member is disposed between the cover and the end surface of the shell.

9 . The sound generating device of claim 7 , wherein the housing comprises an shell having an inner sidewall, and the first connecting portion of the vibration member is attached onto the inner sidewall of the housing.

10 . The sound generating device of claim 7 , wherein the housing comprises an shell having an end surface, and a cover covering the end surface, the cover comprises a body portion abutting against the end surface of the shell and an extended portion extending from the body portion towards the vibration body, wherein the first connecting portion of the vibration member is disposed between the extended portion and the inner sidewall of the housing.
