Abstract

A diaphragm for a high water pressure waterproof micro speaker is provided. The diaphragm for a waterproof micro speaker includes: an annular dome portion formed of an elastic membrane material and having a dome portion protruding upward or downward; an annular outer peripheral portion attached to an outer periphery of the dome portion and injection molded with a rigid material; an annular inner peripheral portion attached to an inner periphery of the dome portion and injection molded with a rigid material; and a central diaphragm attached to the center of the inner peripheral portion, in which the outer peripheral portion and the inner peripheral portion are attached to the edge portion by double injection molding.

Description

technical field [0001] The present disclosure relates to diaphragms for high water pressure waterproof microspeakers. Background technique [0002] Mobile devices are equipped with miniature speakers to reproduce notification sounds or content sounds for the user. In order to maximize the convenience of the mobile device, there are more and more mobile devices with a waterproof function, and accordingly, the miniature speakers installed in the mobile devices themselves need to have a waterproof function. [0003] figure 1 is a view illustrating a waterproof microspeaker according to the related art, the structure of which is disclosed in Korean Patent Registration No. 10-1889315. The diaphragm body includes a rigid top portion 11 , a silicone rubber membrane 12 and a plastic support 13 coupled to the edge of the silicone rubber membrane 12 . The silicone rubber membrane 12 includes a planar coupling portion 12a positioned at a central position, a connecting portion 12b po...
