Loudspeaker module and electronic equipment

Abstract

The invention discloses a loudspeaker module and electronic equipment, the loudspeaker module comprises a shell, a loudspeaker individual and a damping block, wherein the shell is provided with an inner cavity; the shell is provided with a leakage hole; the loudspeaker individual is arranged in the inner cavity and divides the inner cavity into a front sound cavity and a rear sound cavity; the rear sound cavity is communicated with the leakage hole; the damping block covers the leakage hole; the damping block is provided with a first hole and an airflow channel; the axis of the first hole andthe axis of the leakage hole are arranged at intervals; the airflow channel communicates with the leakage hole and the first hole; and at least one groove is concavely formed in the cavity wall of theairflow channel. Before the airflow is exhausted to the outside, the airflow is buffered and denoised in the airflow channel.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to loudspeaker modules and electronic equipment. Background technique [0002] The loudspeaker module is an important acoustic component of portable electronic equipment, which is used to complete the conversion between electrical signals and sound signals, and is an energy conversion device. The speaker module includes a shell and a speaker unit housed in the shell. The speaker unit divides the inner cavity of the entire module into two cavities, a front cavity and a rear cavity, and the front cavity is connected to the outside of the speaker module. [0003] During the working process of the speaker product, the reciprocating motion of the energized voice coil under the action of electromagnetic force will make the air in the rear acoustic cavity continuously compressed, and the air flow pulsation noise generated by the air flow will lead to unstable acoustic performance, noi...

AI Technical Summary

Problems solved by technology

[0003] During the working process of the speaker product, the reciprocating motion of the energized voice coil under the action of electromagnetic force will continuously compress the air in the rear acoustic cavity, and the air flow pulsation noise generated by the air flow will lead to unstable acoustic performance, noise, and asymmetric displacement

[0004] In the related technology, the airflow pulsation noise is reduced by opening a leak hole in the rear acoustic cavity and bonding mesh cloth at the position of the leak hole, but the damping effect is limited, and the airflow disturbance sound and flow velocity are still relatively large, which cannot meet the acoustic requirements
