Abstract

The present invention provides a loudspeaker box, which includes a housing with a storage space and a sound-generating unit partially accommodated and fixed in the storage space. The monomer includes a diaphragm for vibrating and sounding; the upper cover includes an upper cover extension wall fixedly connected to the lower cover, and a main body part that bends and extends from the upper cover extension wall to the sounding monomer, and the main part penetrates through the outer leaking diaphragm. The sound outlet, the sound unit is equipped with a positioning boss; the shell and the positioning boss are made of metal, and the sound unit is welded and fixed to the main body through the positioning boss; the lower cover is located on the side of the sound unit away from the diaphragm and is connected to the The extension wall of the upper cover forms a seal, and the upper cover, the lower cover and the sound emitting unit together form the rear acoustic cavity. Compared with the related art, the volume of the rear acoustic cavity of the speaker box of the present invention is large, and the low-frequency acoustic performance is excellent.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic conversion, in particular to a speaker box used in portable mobile electronic products. 【Background technique】 [0002] Speaker boxes are widely used in portable mobile electronic products, such as mobile phones, to convert audio signals into sound playback. The loudness of the speaker box is large and the vibration amplitude is large. [0003] The loudspeaker box in the related art includes a housing with a receiving space and a sounding unit fixedly accommodated in the receiving space. Since the housing is generally made of plastic, it is mainly made by injection molding. In addition, the assembling of the sounding unit When the body is used, it is necessary to use ultrasonic welding to package the sounding monomer on the shell. [0004] However, in the related art, in order to realize the ultrasonic welding between the sounding unit and the shell, the shell has a certain thickness to ensure th...
