Abstract

PURPOSE:To improve the distorsion and crosstalk and to increase the output voltage by supporting a vibrating system at one point. CONSTITUTION:In order to support a vibrating system at one point, a pivot fulcrum is formed at the trailing end of a cantilever 15 to effect the pivotal support from the back, and a coil plate 17 is jointed to the trailing portion of the cantilever. A damper rubber 20 is arranged in front of the plate 17, and a hollow coil 18 is mounted on the back of the plate 17 and has its hollow portion, in which a pole piece is arranged so that the magnetic gap may be reduced to establish a high magnetic flux density.
