<p>The present invention relates to a micro speaker with a waterproofing structure. The micro speaker includes: a frame; a magnetic circuit which is coupled to the inside of the frame; a voice coil whose lower end part is located inside the magnetic circuit, vibrating upward and downward by the mutual electromagnetic force with the magnetic circuit; a diaphragm which has a plane central part, a plane outer circumferential part, and a ring-shaped dome part protruding toward the upper part between the central and the outer circumferential parts; and a suspension which shows vibrations of the voice coil, is seated on the frame, and has a ring-shaped outer circumferential part whose center is punched, a central part located at the punched center at an interval with the outer circumferential part, and a connection part connecting the outer circumferential part and the central part. The central part of the vibrating plate and the central part of the suspension are attached to each other and the outer circumferential part of the vibrating plate and the outer circumferential part of the suspension are attached to each other.</p> |
