Abstract

The invention discloses a loudspeaker box, which comprises a lower cover, an upper cover arranged on the lower cover and jointly enclosing a storage space, a sound-generating unit accommodated in the storage space, an auxiliary leakage part with a ventilation space, and sound-absorbing particles; The single unit and the upper cover form the front cavity, and the sounding unit, the lower cover and the upper cover together form the rear cavity. The sounding unit is provided with a leakage hole connecting its internal cavity with the rear cavity. The sounding unit includes the side, and the leakage The hole leaks from the side; the auxiliary leakage part is placed in the rear cavity, and the sound-absorbing particles are filled in the rear cavity; the auxiliary leakage part completely covers the leakage hole and communicates the air-ventilating space with the leakage hole, the air-permeable space communicates with the air in the rear cavity, and the sound-absorbing particles are located in the auxiliary outside the leak. Compared with the related art, the speaker box of the present invention has good reliability and excellent acoustic performance.

Description

【Technical field】 [0001] The invention relates to an electroacoustic device, in particular to a speaker box used in portable electronic products. 【Background technique】 [0002] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise.
