Problems solved by technology

Therefore, the amount of adhesive applied, the location of application and the bonding pressure will affect the failure rate of waterproofing
Another disadvantage is that the waterproofing failure rate is affected by how well the waterproofing tape remains free of foreign matter and the amount of compression since audio components are assembled to electronic devices using waterproofing tape

Abstract

A waterproof speaker having a waterproof rating of 8 or more and that is capable of providing a waterproof function at a high water pressure is provided. The waterproof microspeaker includes: a framecomprising a sidewall and a flange portion extending outward from an upper edge of the sidewall; a vibrating portion within the frame; a diaphragm mounted on the flange portion of the frame; and a waterproof ring placed on a sidewall of the frame and configured to protrude further outward than the flange portion of the frame.

Description

technical field [0001] The invention relates to a high water pressure waterproof loudspeaker. Background technique [0002] Mobile devices have tiny speakers that play user notification sounds or audio content. More and more mobile devices are equipped with daily life waterproofing to maximize the convenience of mobile devices. The need to make microspeakers installed in mobile devices waterproof is in line with this trend. [0003] figure 1 is a view showing a waterproof microspeaker structure disclosed in Korean Patent Registration No. 10-1889315 according to conventional technology. The main body of the diaphragm comprises a rigid top part 11 , a silicone rubber membrane 12 and a plastic support 13 attached to the edge of the silicone rubber membrane 12 . The silicone rubber film 12 includes: a flat attaching portion 12a positioned at the center; a connecting portion 12b positioned at the edge and injection molded and attached to the plastic support 13; and positioned...
