High-water pressure waterproof microspeaker
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 frame comprising 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.
1. A high-water pressure waterproof microspeaker configured to be assembled in a microspeaker installation space of a mobile device and comprising a vibrating portion within a frame, wherein the vibrating portion includes a diaphragm and a vibrating member that vibrates the diaphragm, the high-water pressure waterproof microspeaker further comprising:
the frame comprising a sidewall and a flange portion extending outward from an upper edge of the sidewall;
the diaphragm mounted on an upper surface of the flange portion of the frame; and
a waterproof ring placed on an outer surface of the sidewall of the frame and below the flange portion and configured to protrude further outward than the flange portion of the frame so that an outer rim of the waterproof ring is larger than the microspeaker installation space of the mobile device,
wherein when the microspeaker is assembled in the microspeaker installation space of the mobile device, the waterproof ring is compressed in the microspeaker installation space.
2. The high-water pressure waterproof microspeaker of claim 1 , wherein the frame is made from either steel material or injection-molding material.
3. The high-water pressure waterproof microspeaker of claim 1 , wherein the diaphragm comprises:
a center portion positioned at a center of the diaphragm;
a ring-shaped dome portion formed around the center portion and protruding upward or downward; and
a seating portion formed outside of the ring-shaped dome portion and seated on the frame.
4. The high-water pressure waterproof microspeaker of claim 3 , wherein the seating portion comprises:
a first seating portion seated on an inner surface of the sidewall of the frame; and
a second seating portion seated on an upper surface of the flange portion of the frame.
5. The high-water pressure waterproof microspeaker of claim 1 , wherein the waterproof ring comprises an injection-molded liquid silicone rubber.
6. The high-water pressure waterproof microspeaker of claim 1 , wherein the waterproof ring is a cured-in-place gasket.
7. The high-water pressure waterproof microspeaker of claim 1 , further comprising an adhesive applied to the flange portion of the frame, wherein the adhesive has an adhesive force by means of heat and pressure, and wherein the diaphragm and the flange portion of the frame are bonded together by means of heat and pressure.
