WIPO Patent Application WO/2016/206328

A1

Provided is a mini loudspeaker related to the technology field of electroacoustic products. The mini loudspeaker comprises a shell. A vibration system and a magnetic circuit system are accommodated in the shell. The shell is made up by combining at least two shell bodies. A protruding sealing portion is provided on one of the shell bodies at a sealing part where the shell body is sealed with another one of the shell bodies. The sealing portion is integrally formed with the shell body through bi-colour injection moulding. The hardness of the material of the sealing part is lower than that of the shell body. The sealing part has compressibility. The shell body is further provided with a joining part for joining with another one of the shell bodies. The joining part and the sealing part are positioned at the same side of the shell body. The mini loudspeaker of the present invention solves the technical problem of a poor sealing between shell bodies of a mini loudspeaker in the prior art. With a good sealing, the mini loudspeaker of the present invention solves the sealing problems under the condition of a small space in a product and ensures good quality of the inner cavity and an aesthetic appearance of the mini loudspeaker.
