Loudspeaker box

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...

AI Technical Summary

Problems solved by technology

[0004] However, in the speaker box of the related art, the flexible circuit board is fixed to the housing by welding, and the assembly process includes such processes as fitting, soldering, ultrasonic bonding of the upper cover and the lower cover, and slotting glue, and the assembly process is complicated. , needs hot spot, pressure maintaining and other processes. Due to the small size of the flexible circuit board and poor assembly accuracy, it is necessary to apply notch glue to the outlet groove after assembly. If the notch glue is not applied in place, the outlet groove will have air leakage. risk, meanwhile, flexible circuit boards are more expensive
