Abstract: A loudspeaker module, relating to the technical field of electroacoustic products. The loudspeaker module comprises a housing. A loudspeaker unit is accommodated in the housing. An electrical connection member which is a metal sheet is fixed on the housing. An inner bonding pad is disposed at one end of the electrical connection member, and an outer bonding pad is disposed at the other end of the electrical connection member. The inner bonding pad is located in the housing and is electrically connected to the loudspeaker unit. The outer bonding pad is exposed outside the housing and is electrically connected to a terminal circuit. The loudspeaker module of the present invention solves the technical problems in the prior art such as poor tone quality, low reliability, and a complicated assembling process of a loudspeaker module. The loudspeaker module of the present invention has good tone quality, high reliability, a long service life, a simple assembling process, and high production efficiency, and occupies a small space of a terminal, thereby facilitating the development of the terminal towards smaller size.

Abstract: A loudspeaker vibration system includes a diaphragm body part and a voice coil engaged at a lower side of the diaphragm body part. The diaphragm body part includes a rigid dome part, a silicon rubber membrane, and a plastic support engaged to an edge of the silicon rubber membrane. The dome part is engaged at a middle position of the silicon rubber membrane. A convex or concave bent ring part is provided at a location at an outer side of the dome part on the silicon rubber membrane. A spacing between the edge at an outer side of the dome part and an edge of the bent ring part closer to the dome part is in a range of 0.02 mm and 0.2 mm, and colloid is disposed in a gap between the dome part and the bent ring part. The loudspeaker vibration system according to the present disclosure may improve product sensitivity, reduce distortion and enhance acoustic performance of the product.
