Abstract

The present disclosure discloses a speaker box including a housing having a receiving space, and a speaker unit mounted on the housing and dividing the receiving space into a front chamber and a rear chamber isolated from each other; a support member is received in the rear chamber, including a first fixation portion fixed to the speaker unit, a second fixation portion fixed to the housing, and a support portion connecting the first fixation portion and the second fixation portion; a sound hole is provided on the housing configured to connect the front chamber with outside; the first fixation portion is fixed to a yoke; the speaker box in the present disclosure has higher fixation strength and higher drop reliability.

First claim

What is claimed is:

1 . A speaker box comprising:
a housing, having a receiving space; a speaker unit mounted on the housing and dividing the receiving space into a front chamber and a rear chamber isolated from each other, comprising: a diaphragm configured to vibrate to generate sound, enclosing the front chamber with the housing; and a yoke spaced apart from the housing; a support member received in the rear chamber, comprising a first fixation portion fixed to the speaker unit, a second fixation portion fixed to the housing, and a support portion connecting the first fixation portion and the second fixation portion; wherein a sound hole is provided on the housing configured to connect the front chamber with outside; the first fixation portion is fixed to the yoke; the yoke comprises a bottom surface away from the diaphragm along a vibration direction; the first fixation portion is welded to the bottom surface; the second fixation portion is welded to the housing.

2 . The speaker box as described in claim 1 , wherein the support member further comprises a first arch portion connecting the first fixation portion and the support portion, and a second arch portion connecting the second fixation portion and the support portion; the support portion is spaced apart from the bottom surface along the vibration direction.

3 . The speaker box as described in claim 1 , wherein the housing comprises an upper cover having the sound hole, and a bottom cover enclosing the receiving cavity with the upper cover; the second fixation portion is fixed to the bottom cover.

4 . The speaker box as described in claim 3 , wherein the bottom cover comprises a bottom wall spaced apart from the bottom surface of the yoke along the vibration direction, and a side wall bending from outer edge of the bottom wall and extending to be fixed to the upper cover; the second fixation portion is welded to the side wall.

5 . The speaker box as described in claim 4 , wherein the housing is in a rectangular shape; the side wall comprises two first wall opposite to each other and two second wall opposite to each other; the support member comprises two second fixation portions; each of the two second fixation portions fixedly connects to one first wall separately.

6 . The speaker box as described in claim 5 , wherein the first wall extends along a long axis.

7 . The speaker box as described in claim 5 , wherein the first fixation portion comprises a hollow portion penetrating thereon along the vibration direction.

8 . The speaker box as described in claim 1 , wherein a projection of the support portion overlaps with a projection of the bottom surface along the vibration direction.
