Problems solved by technology

[0004] However, the front cover and the rear cover of the loudspeaker box in the related art 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 acoustic performance

Abstract

The invention provides a speaker box which comprises a shell, a sound production unit and a bracket made of a plastic material, and the shell is made of a metal material and comprises an upper cover and a lower cover; the upper cover comprises an upper cover plate, an upper cover side wall, a sound outlet and a side wall extension part surrounding the sound outlet; a support comprises an annular support fixing part and a support sound guide part which are fixed on the upper cover plate, the sound production unit is supported on the support fixing part and spaced from the upper cover, the support fixing part surrounds the periphery of the sound production unit and is hermetically fixed with the sound production unit, and the sound production unit, the support and the upper cover jointly define a front sound cavity. The sound production unit, the support, the upper cover and the lower cover jointly form a rear sound cavity. The support sound guide part is provided with a sound guide channel, and the sound guide channel communicates the front sound cavity with the outside through the sound outlet; the side wall extension part is arranged around the sound guide channel and is embeddedand fixed in the support sound guide part; 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, the front cover and the rear cover of the loudspeaker box in the related art 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 c...
