The permanent magnets (116, 117) are independent of each other; the polarity of the magnetic pole of one side of the permanent magnet in the direction facing the driving coil (114) is S or N, and the other side of the permanent magnet has in the direction facing the driving coil (114) a polarity opposite to the polarity of the magnetic pole of said one side of the permanent magnet; the angle between the direction of the magnetic lines of force inside the permanent magnets (116, 117) and the direction of the longitudinal axis of the driving coil iron core (115) is greater than 45 and smaller than 135; the permanent magnets (116, 117) may move with respect to the transducer elastic element retainer (124). When the current of the driving coil (114) is alternating current having a frequency of f0, the direction of movement of the permanent magnets (116, 117) is approximately parallel to the direction of the longitudinal axis of the driving coil iron core (115), and the angle between the two is greater than 170 and smaller than 190. The present appliance has a simple and compact structure and is low in cost, easy to assemble and steady in rotation; it has low damping and is safe and reliable.

A holder is used while attached to a chassis of a vibration generator that moves a vibrator to generate a vibration. The holder includes a vibrator retention unit retaining the vibrator, a fixed unit fixed to the chassis, and an arm. The arm connects the fixed unit and the vibrator retention unit, and the arm supports the vibrator retention unit while the vibrator retention unit can be displaced with respect to the fixed unit. The fixed unit, the arm, and the vibrator retention unit are integrally formed using resin.
