Abstract
An electro-vibration transducer for converting sound signals into body-sensible acoustic vibrations to permit the listener to sense sound directly through his or her body and having a wide effective bandwidth and good transient response characteristic. An auxiliary vibrator, namely, a weight, is attached to a magnetic circuit of the transducer via an elastic member. The auxiliary vibrator can be attached to an outer annular surface of the magnetic circuit, or to a lower planar surface thereof. Preferably, the elastic member is made of a visco-elastic material.
