Benefits of technology

The present utility model speaker box has a clipping wall and an air-permeable isolating component that divide the back cavity into two parts, with the second part filled with acoustic absorbing particles. This structure improves low-frequency performance and increases the volume of the speaker box. The connection between the two parts is achieved by installing the air-permeable isolating component vertically on the lower cover, which eliminates the need for a gap between the lower cover and the isolating component, and reduces the hot melt wall, further increasing the volume of the speaker box and improving its low-frequency performance.

Problems solved by technology

The hot melt wall and the gap structure of leakage occupy the volume of the auxiliary sound cavity which works as a virtual sound cavity, reducing the volume of the virtual sound cavity and affecting the low frequency acoustic performance of the speaker box.

Abstract

A speaker box includes a lower cover; an upper cover engaging with the lower cover for forming an accommodating space; a speaker unit accommodated in the accommodating space; a front cavity formed by the speaker unit and the upper cover; a back cavity formed by the speaker unit, the lower cover and the upper cover; a clipping wall formed by the upper cover extending toward the lower cover till reaching the lower cover; an air-permeable isolating component fixed on and clamped to the clipping wall and dividing the back cavity into a first back cavity and a second back cavity communicated with the first back cavity. The speaker unit is located in the first back cavity, the second back cavity is filled with acoustic absorbing particles, and the air-permeable isolating component seals the acoustic absorbing particles inside the second back cavity.

Description

FIELD OF THE PRESENT DISCLOSURE[0001]The present disclosure relates to the field of electroacoustic transducers, more particularly to a sound device for converting electric signals to audible sounds.DESCRIPTION OF RELATED ART[0002]With the upcoming of mobile internet era, the number of smart mobile equipment keeps increasing.
