Abstract

The invention provides a loudspeaker box, which comprises a shell with an accommodating space and a sound production monomer partially accommodated and fixed in the accommodating space, and is characterized in that the shell comprises an upper cover and a lower cover which covers the upper cover and defines the accommodating space together with the upper cover, and the sound production monomer comprises a vibrating diaphragm for vibration sound production; the upper cover comprises an upper cover extension wall fixedly connected with the lower cover and a main body part bent and extended fromthe upper cover extension wall to the sound production monomer, the main body part is provided with a sound production port exposed out of the vibrating diaphragm in a penetrating manner, and the sound production monomer is provided with a positioning boss; the shell and the positioning boss are both made of metal materials, and the sound production single body is welded and fixed to the main bodypart through the positioning boss. The lower cover is located at one side, away from the vibrating diaphragm, of the sound production monomer and forms sealing with the upper cover extension wall. The upper cover, the lower cover and the sound production monomer jointly enclose a rear sound cavity. Compared with the prior art, the loudspeaker box has the advantages that the volume of the rear sound cavity 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...
