A speaker box includes a metal housing defining an accommodating cavity, a speaker received in the accommodating cavity, and at least two metal pieces arranged between the metal housing and the speaker. The speaker includes a vibrating diaphragm. The speaker includes a frame and a magnetic yoke fixed to the frame. The at least two metal pieces are welded and fixed to the magnetic yoke and the metal housing. Compared with the prior art, by welding the at least two metal pieces with the speaker through laser, reliability of the speaker box is improved when the speaker box suddenly drops, a manufacturing process is optimized, and costs are saved.

Speaker box

A speaker box includes a housing, a speaker unit and a flexible circuit board. The housing includes a base defining a through hole, and a cover. The flexible circuit board includes an end received in the housing and an opposite end exposed to outside of the housing. The flexible circuit board includes a first surface facing the cover and a second surface opposite to the cover. A first pad and a second pad are disposed at the second surface. The flexible circuit board includes a first mounting part, a second mounting part and a bending part. The first pad is arranged on the first mounting part and configured to be electrically coupled to the speaker unit. The second pad is arranged on the second mounting part and configured to be electrically coupled to external circuits. The second pad is exposed to outside of the housing via the through hole.

The present disclosure provides a speaker box, including an upper cover plate and a lower cover plate which cooperate with each other to form accommodating space and a speaker accommodated in the accommodating space, the speaker includes a diaphragm for vibrating and sounding, the diaphragm and the upper cover plate form a front cavity, the speaker box further includes a sounding channel formed by surrounding of the upper cover plate and the lower cover plate, configured to communicate the front cavity with external environment, and a sounding hole communicated with the sounding channel, the speaker is fixed on the upper cover plate, the sounding hole is provided on the lower cover plate, an extending direction of the sounding channel is perpendicular to a vibration direction of the diaphragm. By adopting the speaker of the present disclosure, the assembling yield is high and the sounding effect is good.
