Abstract: Disclosed is a bone-conduction transducer comprising a plate-shaped yoke bent to form a pair of cut portions at both ends thereof; voice coils fitted to a center extension of the cut portions; a magnet and a plate of rectangular parallelepiped shape disposed between the voice coils; and a diaphragm minutely spaced from a lower part of the plate. The present invention constructed as above has an advantage of optimizing the bone-conduction transducer by fitting the voice coils to both the center extensions of the yoke to convert electrical signals into magnetic attractive and repulsive forces, and arranging the magnet and the plate between the voice coils.
