Detailed Description
The present invention will be further described with reference to the accompanying drawings 1 to 4.
The invention provides a loudspeaker module 100, which comprises an upper cover 1, a lower cover 4 and a loudspeaker monomer 3, wherein the lower cover 4 and the upper cover 1 are connected in a covering manner to form an accommodating space, and the loudspeaker monomer 3 is accommodated in the accommodating space, and the upper cover 1 and the lower cover 4 jointly form a shell of the loudspeaker module 100.
The upper cover 1 comprises a bottom wall 12 and a side wall 11 which is bent and extended from the bottom wall 12 to the lower cover 4, wherein the side wall 11 is connected end to end and arranged around the accommodating space. The housing is further provided with a supporting wall 13 for supporting and fixing the speaker unit 3 and a retaining wall 131 extending from the supporting wall 13 and surrounding the speaker unit 3, the supporting wall 13 may be a hollow ring or a hollow rectangle, and in this embodiment, the supporting wall 13 is a hollow rectangle.
In the present embodiment, the supporting wall 13 is formed by bending and extending the bottom wall 12 toward the lower cover 4, and the retaining wall 131 is wound around the upper surface 132 of the supporting wall. The speaker unit 3 is supported and fixed on the upper surface 132 of the supporting wall, the speaker unit 3 is accommodated in the retaining wall 131, the silica gel 2 is disposed between the speaker unit 3 and the retaining wall 131, the silica gel 2 is in a hollow ring shape, and the silica gel 2 can be wound around the side surface of the speaker unit 3 or disposed in the retaining wall 131. When the silica gel 2 is wound on the side surface of the loudspeaker single body 3, the silica gel 2 and the basin frame of the loudspeaker single body 3 are integrally molded or glued by double-shot molding; when the silica gel 2 is disposed in the retaining wall 131, the silica gel 2 and the retaining wall 131 are molded integrally by two-color injection molding or glued.
Preferably, the silicone rubber 2 is wound around the side surface of the speaker unit 3, and the silicone rubber 2 includes a main body portion 21 and a chamfered portion 22, and the chamfered portion 22 is located on the periphery of the main body portion 21 on the side close to the support wall 13.
