Abstract

The present invention discloses a diaphragm for a sound converter including a first diaphragm (62) having a central portion which is a plane surface and a side dome formed around the central portion and a second diaphragm (64) formed at the central portion of the first diaphragm (62). The sound converter maximizes the volume of a magnet (40) mounted therein, and thus improves a sound pressure of low frequency bands. In addition, the sound converter allows a lead wire of a coil portion (50) to be pulled out without interfering with other elements, and thus stably transmits electrical signals without damaging the lead wire or the other elements.
