Acoustic transducer device

摘要

The present invention relates to a sound converter, and, more particularly, to a sound converter which can solve a problem in that a vibration space decreases in the sound converter requiring high outputs, as the overall height of a voice coil increases.

主权项

1. A sound converter, comprising:
a frame; a yoke assembly provided on one side of the frame and provided with a magnet; a damper having a central portion formed at the center in a certain shape, a seating portion spaced apart from the central portion and seated on the frame, and a connection portion elastically connecting the seating portion to the central portion; a side diaphragm having an inner circumference portion overlapping with the edge of the central portion of the damper and an outer circumference portion overlapping with the seating portion and seated on the frame, said side diaphragm being attached to lower parts of the central portion and the seating portion of the damper, and said side diaphragm being formed in a dome shape having a central portion more projecting than the inner circumference portion and the outer circumference portion; and a voice coil mounted on the overlapping portion of the inner circumference portion of the side diaphragm and the central portion of the damper, wherein the central portion of the dome shape of the side diaphragm projects to mounting side of the voice coil.
