Abstract
The present invention discloses a sound converter with an enclosure which utilizes an outer space to expand a resonance space. The sound converter with the enclosure includes a frame being equipped with a magnetic circuit for forming a magnetic field in a predetermined gap, a voice coil at least partially positioned in the gap, a diaphragm adhered to the voice coil and inserted into a diaphragm seating portion of the frame, a protector formed at the upper portion of the diaphragm, and an enclosure case coupled to the frame, for defining the inner space of the enclosure which is the resonance space. A vent is provided at the enclosure case so that the inner space of the enclosure can communicate with the outer space. This configuration can secure a wide resonance space.
