Abstract

The invention provides a loudspeaker box. The loudspeaker box comprises a shell and a sound production monomer; the shell is provided with a containing space; the sound production monomer is containedin the containing space; the sound production monomer is provided with a bonding pad; the loudspeaker box further comprises a soldering lug; the soldering lug comprises a main body part, an elastic pin and a conductive terminal; the main body part is fixed on the shell by injection moulding; the elastic pin extends from the main body part; the conductive terminal is connected with the main body part; the elastic pin elastically abuts against the bonding pad; and the conductive terminal is electrically connected with an external circuit. Compared with the prior art, the loudspeaker box provided by the invention is as follows: the soldering lug fixed on the shell by injection moulding is connected to the sound production monomer and the external circuit; the steps of soldering, maintainingpressure, painting notch glue and the like can be avoided; compared with assembly, injection moulding is relatively high in fixation precision; the yield of the loudspeaker box is relatively high; a flexible circuit board is replaced by the soldering lug; the cost is reduced; the wire outlet groove of the flexible circuit board is cancelled; the gas leakage problem of the wire outlet groove is completely evaded; the elastic pin of the soldering lug is connected to the sound production monomer; and thus, the sound production monomer also can be contacted with the elastic pin of the external circuit without arrangement of the elastic pin.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic conversion, in particular to a speaker box applied to portable electronic products. 【Background technique】 [0002] With the rapid development of science and technology, the penetration rate of audio equipment is getting higher and higher. Among the many entertainment methods, high-quality music enjoyment is gradually popularized by the public. Therefore, speaker boxes for playing audio are widely used until now. of smart mobile devices. [0003] The speaker box in the related art includes a housing with a receiving space, a sounding unit accommodated in the housing, the sounding unit is provided with a single pad for electrical connection, assembled in the housing and a conductive terminal connected to the outside, and a flexible circuit board connecting the conductive terminal and the single pad. [0004] However, in the speaker box of the related art, the flexible circuit board is fixed to th...
