Loudspeaker cabinet

Abstract

The invention provides a loudspeaker cabinet. The loudspeaker cabinet includes a bottom cover, a top cover, a side plate, a sounding monomer, a cyclic convex wall and a ventilating separator, whereinthe side plate connects the bottom cover and the top cover, so as to form accommodation space through enclosure, together with the bottom cover and the top cover; a front cavity is formed through enclosure of the sounding monomer, the top cover and the side plate together; a back cavity is formed through enclosure of the sounding monomer, the bottom cover and the slide plate together; the convex wall is extended to the direction, far away from the outer wall of the side plate, from the inner wall of the side plate in a convex manner; the ventilating separator is fixedly supported at one side,close to the top cover, of the convex wall, and separates the back cavity into a first back cavity and a second back cavity, together with the convex wall, and the first back cavity and the second back cavity are mutually communicated in air; the sounding monomer is arranged in the first back cavity; acoustic-absorbing particles are filled in the second back cavity; and the ventilating separator packages the acoustic-absorbing particles in the second back cavity. Compared with the related technologies, the loudspeaker cabinet has better low frequency acoustic performance.

Description

【Technical field】 [0001] The invention relates to an electroacoustic device, in particular to a speaker box. 【Background technique】 [0002] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise. Among the many mobile devices, the mobile phone is undoubtedly the most common and portable mobile terminal device. At present, the functions of mobile phones are extremely diverse, one of which is the function of high-quality music. Therefore, speaker boxes for playing sound are widely used in current smart mobile devices. [0003] The speaker box in the related art includes a lower cover, an upper cover that is assembled with the lower cover to form a storage space, a sounding unit accommodated in the storage space, and a shape extending from the upper cover to the lower cover. An annular retaining wall, the sound emitting unit and the upper cover form a front cavity, the sound emitting unit, the upper cover and the lower cover together...

AI Technical Summary

Problems solved by technology

[0004] However, in the speaker box of the related art, the air-permeable baffle and the retaining wall are connected by thermal fusion, and the retaining wall occupies a relatively large volume in the rear cavity, so that the volume of the rear cavity is constant. In some cases, the volume of the auxiliary sound cavity used as a virtual sound cavity cannot be maximized, thereby limiting the acoustic performance of the speaker box
