Loudspeaker module

Abstract

The invention discloses a loudspeaker module, and relates to the technical field of electroacoustic products. The loudspeaker module comprises a module shell, wherein a loudspeaker cell is held in the module shell; the loudspeaker cell comprises a cell front cover and a cell shell which are combined together; a vibrating system and a magnetic circuit system are held in a space enclosed by the cell front cover and the cell shell; a plurality of positioning columns are arranged on the outer side of the side wall of the cell shell; each positioning column projects out of the side wall surface of the cell shell, and extends from the upper end of the cell shell to the lower end of the cell shell along the side wall of the cell shell; positioning bosses are arranged at positions corresponding to the positioning columns on the module shell respectively; and a positioning hole matched with each positioning column is vertically formed in each positioning boss respectively. A cell positioning structure in the loudspeaker module is small in size, and occupies a small space. The acoustic performance of the module is high, and a module assembly process is simple, and is easy to operate.

Description

technical field [0001] The invention relates to the technical field of electro-acoustic products, in particular to a speaker module. Background technique [0002] The speaker 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. The speaker module usually includes a module housing, and the module housing accommodates a speaker unit, and the speaker unit needs a positioning structure to be fixed in the inner cavity of the module. Existing speaker modules usually ensure the positioning of the speaker unit in the inner cavity of the module through the blocking wall arranged on the module shell and the extrusion of the upper and lower shells of the module. However, with the continuous development of portable electronic devices. The development of light, thin and small, the speaker module must also become thinner and smaller, so that th...

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
