Problems solved by technology

[0002] Speakers in the prior art generally store the sounding unit inside the box, and the sounding unit has only a single-sided sound film. Due to the small vibration area, the sound is not loud, and at the same time, the single-sided sound film is not conducive to eliminating its own vibration, thus affecting sound quality

Abstract

The invention provides a loudspeaker box, which includes a box body and a sounding unit, the sounding unit includes a casing and an upper sound film and a lower sound film installed on the casing, and the upper sound film, the lower sound film and the casing surround A first cavity is formed, the casing includes a main body part fixedly connected with the upper sound film and the lower sound film and a connecting platform protruding outward from the main body part, and the box body includes a support part having a second cavity and a projection , the sounding unit is fixed to the bump through the connecting platform, the housing is provided with a first leakage channel communicating with the first cavity, the box is provided with a second leakage channel communicating with the second cavity, and the first leakage channel is It communicates with the second leakage channel to form a rear cavity leakage channel, and the first cavity communicates with the second cavity through the rear cavity leakage channel; Groove through which the anterior cavity communicates with the outside world. The loudspeaker box of the present invention increases the vibration area of ​​the sounding unit and can counteract its own vibration, thereby improving the quality of sounding.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic conversion, in particular to a speaker box. 【Background technique】 [0002] Speakers in the prior art generally store the sounding unit inside the box, and the sounding unit has only a single-sided sound film. Due to the small vibration area, the sound is not loud, and at the same time, the single-sided sound film is not conducive to eliminating its own vibration, thus affecting Sound quality. [0003] Therefore, it is necessary to provide a speaker box to solve the above problems. 【Content of invention】 [0004] The purpose of the present invention is to provide a speaker box, which has the advantages of large vibration area, self-vibration cancellation and small volume. [0005] Technical scheme of the present invention is as follows: [0006] The present invention provides a speaker box. The speaker box includes a box body and a sound unit arranged outside the box body. The upper sound me...
