speaker module

Abstract

A loudspeaker module comprising a module casing. A loudspeaker unit body (30) is accommodated within the module casing. The loudspeaker unit body (30) comprises a unit body front cover (32) and a unit body casing (34) which are combined with each other. A vibration system and a magnetic circuit system are accommodated within a space enclosed by the unit body front cover (32) and the unit body casing (34). A plurality of positioning columns (340) are arranged outside sidewalls of the unit body casing (34). Each of the positioning columns (340) protrudes out of the surface of the sidewall of the unit body casing (34), and extends from the upper end of the unit body casing (34) to the lower end of the unit body casing (34) along the sidewall of the unit body casing (34). Positioning bosses (22) are individually arranged at positions on the module casing corresponding to the positioning columns (340). Positioning holes (222) which are adapted for the positioning columns (340) are individually vertically arranged on the positioning bosses (22). The positioning structure for a unit body of the loudspeaker module is small, and occupies smaller space. The module has high acoustic performances, and the assembly process of the module is simple and easy to operate.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a loudspeaker module. Background technique [0002] The loudspeaker module is an important acoustic component in portable electronic equipment, which is used to complete the conversion between electrical signals and sound signals, and is an energy conversion device. A loudspeaker module usually includes a module casing, in which a speaker unit is accommodated, and the speaker unit needs a positioning structure to be fixed in the inner cavity of the module. Existing loudspeaker modules usually ensure the positioning of the loudspeaker monomer in the inner cavity of the module through the retaining wall arranged on the module casing and the extrusion of the upper and lower casings of the module. However, as portable electronic devices continue to The development in the direction of thinness and compactness leads to the speaker module must also become thinner and s...

Problems solved by technology

Existing loudspeaker modules usually ensure the positioning of the loudspeaker monomer in the inner cavity of the module through the retaining wall arranged on the module casing and the extrusion of the upper and lower casings of the module. However, as portable electronic devices continue to The development in the direction of thinness and compactness leads to the speaker module must also become thinner and smaller, so that the space inside the speaker module becomes smaller and smaller. In this smaller and smaller module cavity If the retaining wall is still used for positioning, the retaining wall will occupy a large part of the cavity space of the module, resulting in the reduction of the acoustic cavity of the module and the decrease of the acoustic performance of the speaker module
