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

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 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 ...
