Problems solved by technology

[0004] However, both the front cover and the rear cover of the related art speaker box are injection-molded, and the sealing of the sounding unit is realized by means of ultrasonic welding. Ultrasonic welding requires more volume, thereby limiting the volume design of the front cavity and the rear cavity , which in turn limits the acoustic performance

Abstract

The invention provides a speaker box which comprises a shell made of a metal material, a sound production monomer and an annular bracket made of a plastic material, and the shell comprises a front cover and a rear cover, and the bracket comprises a bracket main body part and a bracket sound guide part extending from the bracket main body part; the sound production monomer is supported on the support and spaced from the front cover, the bracket surrounds the periphery of the sound production monomer and is hermetically fixed with the sound production monomer, the bracekt sound guide part penetrates through the shell and is at least partially exposed out of the shell, and the bracekt sound guide part is provided with a sound guide channel; the sound production monomer, the bracekt and the front cover jointly form a front vocal cavity, the sound production monomer, the bracekt, the front cover and the rear cover jointly form a rear vocal cavity, and the front vocal cavity is communicatedwith the outside through the sound guide channel. Compared with the prior art, the speaker box is large in cavity size and good in acoustic performance.

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 speaker boxes are loud and have good low-frequency sound effects. [0003] The speaker box of the related art comprises a front cover, a rear cover which is arranged on the front cover and jointly encloses a storage space, and a sound unit accommodated in the storage space, and the sound unit divides the storage space into Anterior and posterior chambers. [0004] However, both the front cover and the rear cover of the speaker box in the related art are injection-molded, and the sounding unit is sealed by ultrasonic welding. Ultrasonic welding requires more volume, thereby limiting the volume design of the front cavity and the rear cavity...
