Electroacoustic transducer and manufacturing method thereof

Abstract

The invention provides an electroacoustic transducer. The electroacoustic transducer comprises elastic sheets and a shell, wherein the shell is formed in a manner that a first sub shell is fixedly bonded to a second sub shell, the elastic sheets are bonded to the first sub shell in an injection molding manner, the first sub shell is provided with bonding faces which are used for being bonded to the second sub shell, the elastic sheets are bent to form bent parts at the bonding faces, the second sub shell is provided with dodging structures which are used for dodging the bent parts, and the bent parts are located at the inner side of the edge of the shell. A manufacturing method of the electroacoustic transducer comprises the following steps of: (1) performing injection molding on the first sub shell at a position corresponding to the bonding parts of the sheet-shaped elastic sheets; (2) performing injection molding on the second sub shell; and (3) fixedly integrating the first sub shell with the second sub shell in a bonding manner, wherein the elastic sheets are bent to form the bent parts from the bonding faces at the end parts of the first sub shell prior to the (3). The electroacoustic transducer and the manufacturing method thereof have the advantages that the occupied space of the elastic sheets can be effectively controlled, the mounting space occupied when the electroacoustic transducer is assembled on a terminal product is saved, and the miniaturization of the terminal product is favored.

Description

Technical field [0001] The invention relates to the field of electroacoustics, in particular to an electroacoustic transducer and a manufacturing method thereof. Background technique [0002] In the prior art, the shrapnel of the electroacoustic transducer and the shell are mainly combined by snapping or injection molding, but when the shrapnel and the shell are combined by snapping, the shrapnel is easy to deflect, and the fixing is not firm, the assembly process is complicated, and Adopt injection molding method to combine, the process is simple and the combination is stable. For the structure in which the shrapnel and the shell are combined by injection molding, in the prior art, after the shrapnel is formed into a sheet-like structure, the joint part of the shrapnel is then injection-molded and combined with the shell. One end of the rear sheet-shaped shrapnel is exposed on the edge of the shell, and then the shrapnel is bent from the edge of the shell to form a bent part of...

Problems solved by technology

[0003] However, when the shrapnel is bent at the edge, the bending part has a certain radian, which will inevitably protrude from the edge of the shell, which undoubtedly increases the volume of the electro-acoustic transducer, so that when the electro-acoustic transducer is installed with the terminal product It is easy to waste the space of the terminal product, which is not conducive to the miniaturization of the terminal product
