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

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Please also see Figure 1-4 As shown, the present invention provides a speaker box 1000, which includes a sounding unit 40 with a diaphragm 400 for vibrating and sounding, a front cover 10 made of a metal material, and an integral injection molding fixedly supported on the front cover 10. The bracket 30 and the rear cover 20 made of metal material are covered on the front cover 10 and the bracket 30 .

[0029] The bracket 30 includes a support body 300 supporting the sounding unit 40 and an outer connection body 310 connected to the support body 300 and enclosing a ring-shaped through hole 320. The ring-mounted through hole 320 extends along the vibration direction of the diaphragm 400 and accommodates the vibration. The membrane 400 and the outer connecting body 310 are provided with a sound guiding channel 311 running through it.

Abstract

The invention provides a loudspeaker box and its assembly process. The loudspeaker box includes a sounding unit, a front cover made of metal material, an integrally injection-molded bracket fixed and supported on the front cover, and a back cover made of metal material; The bracket includes a support body supporting the sounding unit and an outer connecting body connected to the supporting body and forming a ring-shaped through hole. The outer connecting body is provided with a sound guide channel passing through it; the back cover is closed on the front cover and the outer connecting body. The body and the front cover and the outer connecting body form a housing with a storage space, and the sounding unit and the supporting body are accommodated and fixed in the housing space of the housing; the front cover, the supporting body and the sounding unit together form a front acoustic cavity, The sound guide channel connects the front acoustic cavity with the outside world; the sound emitting unit, the outer connecting body, the support body and the rear cover together form the rear acoustic cavity. The loudspeaker box of the present invention can increase the volume of the cavity in the housing, increase the volume of the rear acoustic cavity surrounded by the sound emitting unit and the housing, and further improve the acoustic performance of the loudspeaker box, especially the low-frequency 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 and an assembly process thereof. 【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 ...
