Problems solved by technology

However, when the gas in the rear acoustic cavity is discharged through the leak hole, it will drive the sound-absorbing particles to the leak hole, which will easily cause the sound-absorbing particles to get stuck and block the leak hole, affecting the sound effect

Abstract

The invention discloses a loudspeaker module and electronic equipment, wherein the loudspeaker module includes a casing, a speaker unit and a barrier rib, the loudspeaker unit is arranged in the inner cavity of the outer casing, and the inner cavity of the outer casing The cavity interval is a front acoustic cavity and a rear acoustic cavity, the rear acoustic cavity is filled with sound-absorbing particles, and the cavity wall of the rear acoustic cavity is provided with leakage holes. The barrier ribs are arranged in the rear acoustic cavity and at least partly face the leak hole, and the distance between the part of the barrier ribs facing the leak hole and the leak hole is smaller than the The size of the sound-absorbing particles. The technical solution of the invention can reduce the occurrence of sound-absorbing particles blocking the leakage hole.

Description

technical field [0001] The invention relates to the technical field of sound energy conversion, in particular to a loudspeaker module and electronic equipment. Background technique [0002] Usually, the speaker module includes a casing, and a speaker unit is accommodated in the casing, and the speaker unit divides the entire module inner cavity into two cavities, a front acoustic cavity and a rear acoustic cavity. In order to reduce the low frequency of the module and expand the bandwidth, sound-absorbing particles will be filled in the rear acoustic cavity, and in order to balance the air pressure inside and outside the speaker module, a leakage hole connected to the rear acoustic cavity will be provided on the shell. However, when the gas in the rear acoustic cavity is discharged through the leak hole, it will drive the sound-absorbing particles to rush to the leak hole, which will easily cause the sound-absorbing particles to get stuck and block the leak hole, affecting t...
