Abstract

The invention provides a speaker box, which includes a casing and a sound-generating unit fixedly accommodated in the casing. The sound-generating unit includes a diaphragm for vibrating and sounding; the casing is made of metal material, and the casing includes a first bracket and the front cover and the rear cover respectively covering the opposite sides of the first bracket along the vibration direction of the vibrating membrane, the first bracket is provided with a through hole passing through it; the sounding unit is provided with one side of the diaphragm facing the through hole and The front cover is supported and fixed to the first bracket; the front cover includes a front cover plate arranged opposite to the sounding unit and a side wall of the front cover that is bent and extended from the periphery of the front cover plate to the first bracket and fixed to the first bracket. The wall is provided with a sound outlet running through it; the front cover, the sounding unit and the first bracket together form a front sound cavity, and the sound outlet communicates the front sound cavity with the outside world; the sounding unit, the first branch and the back cover together form rear voice. Compared with the related art, the speaker box cavity of the present invention has a large volume and good acoustic performance.

Description

【Technical field】 [0001] The invention relates to the field of electro-acoustic 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 realize the conversion of audio signals into sound playback. The speaker box has high loudness and good low-frequency sound effect. [0003] The speaker box of the related art includes a front cover, a rear cover that is covered on the front cover and jointly encloses a receiving space, and a sound-emitting unit received in the receiving space, and the sound-emitting unit divides the receiving space into Anterior and posterior chambers. [0004] However, the front cover and the rear cover of the speaker box of the related art are injection-molded, and the sound-generating unit is sealed by ultrasonic welding. Ultrasonic welding requires more volume, thus limiting the volume design of...
