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. The loudspeaker module comprises an outer shell, a loudspeaker single body and a blocking rib body, the loudspeaker single body is arranged in an inner cavity of the outer shell and divides the inner cavity of the outer shell into a front sound cavity and a rear sound cavity, the rear sound cavity is filled with sound absorption particles, and a leakage hole is formed in the cavity wall of the rear sound cavity. The blocking rib body is arranged in the rear sound cavity, at least part of the blocking rib body is right opposite to the leakage hole, and the distance between the part, right opposite to the leakage hole, of the blocking rib body and the leakage hole is smaller than the size of the sound absorption particles. According to the technical scheme, the situation that the leakage hole is blocked by the sound absorption particles can be reduced.

Description

technical field [0001] The invention relates to the technical field of sound energy conversion, in particular to a speaker module and an electronic device. Background technique [0002] Generally, the speaker module includes a housing, and the housing accommodates a speaker unit, and the speaker unit divides the entire inner cavity of the module 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, the rear acoustic cavity will be filled with sound-absorbing particles, and in order to balance the air pressure inside and outside the speaker module, a leakage hole that communicates with the rear acoustic cavity will be set on the casing. However, when the gas in the rear acoustic cavity is discharged through the leakage hole, the sound-absorbing particles will be driven to the leakage hole, which is easy to cause the sound-absorbing particles to get stuck and block the leakage hole, t...
