Abstract

A high water pressure microspeaker is provided. The diaphragm of the waterproof micro speaker includes: a side wall portion having a predetermined height and forming an outer portion; a central portion positioned on an inner side of the dome portion; and a silicone injection molded portion including a dome portion protruding upward or downward along an inner circumference of the side wall portion and a waterproof portion protruding upward or outward from the side wall portion, in which the side wall portion and the central portion are formed of plastic, and the central portion and the side wall portions are integrally manufactured with the silicone injection molded portion by bijection injection molding.

Description

technical field [0001] The present disclosure relates to a high water pressure waterproof microspeaker. Background technique [0002] The mobile device is equipped with a micro speaker for reproducing notification sound or content sound for the user. In order to maximize the convenience of mobile devices, the number of mobile devices having a waterproof function is increasing, and therefore, the micro 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, which has a structure disclosed in Korean Patent Registration No. 10-1889315. The vibrating membrane body includes a rigid top 11 , a silicone rubber membrane 12 and a plastic support 13 coupled to the edges of the silicone rubber membrane 12 . The silicone rubber film 12 comprises: a flat coupling part 12a located at a central position; a connecting part 12b located at the edge and injection-...
