Document Type and Number:
WIPO Patent Application WO/2021/000091
Kind Code:
A1
Abstract:
Provided is a speaker, comprising: a housing having an accommodation space; and a speaker unit accommodated inside the accommodation space. The speaker unit comprises a sound emission surface and a back surface arranged opposite to each other, and a side surface connecting the sound emission surface and the back surface. The back surface is provided with exposed conductive terminals electrically connected to the speaker unit. The housing comprises: a top wall corresponding to the sound emission surface; a bottom wall opposite to the top wall; and side walls extending from edges of the top wall toward the bottom wall. The accommodation space is bounded by the top wall, the bottom wall and the side walls. The speaker further comprises: a circuit board fixed at the housing and electrically connected to the conductive terminals; and solder tabs connected between the conductive terminals and the circuit board, wherein each solder tab comprises a first extension portion fixed at the back surface and corresponding to the conductive terminal and a second extension portion extending from the first extension portion to the bottom wall, and the circuit board is electrically connected to the conductive terminal by means of the second extension portion. In the present invention, connection with a speaker unit is established by means of solder tabs, thereby solving the problem in which a conventional flexible circuit board is too wide and interferes with a cover plate.
