Abstract
Disclosed is a speaker module which relates to the technical field of electroacoustic products and comprises shells (10, 20), wherein a loudspeaker unit (30) is accommodated in the shells (10, 20); an elastic piece (40) is provided on the loudspeaker unit (30); and a conductive structure (22) electrically connected to the elastic piece (40) is provided on the shells (10, 20), the conductive structure (22) is fitted with shell surfaces of the shells (10, 20), one end of the conductive structure (22) is located inside an inner cavity of the module and is electrically connected to the elastic piece (40), the other end of the conductive structure (22) is located outside the inner cavity of the module and is electrically connected to a terminal circuit, and the conductive structure (22) is made of a metal material. The speaker module has advantages such as high stability of a conductive path, a simple structure, a simple and practicable assembling process, and solves technical problems in the prior art that the conductive path of the loudspeaker module is unstable, and the assembling process is complex.
