Patent abstract
An adhering portion of an electroacoustic sound generator provided by the present disclosure, for engaging a front cover and a diaphragm, includes a thickened layer for coupling with the diaphragm, which effectively avoid the glue from overflowing. The hardness of the front cover is 150˜200 HV, which makes it easier to manufacture the thickened layer.
