VIBRATION TRANSMISSION DEVICE

摘要

An example of the purpose of the present invention is to resolve the problems of obtaining a large drive force being difficult and reliably transmitting a large vibration to a user being difficult in a conventional vibration transmission device. To achieve this purpose, a vibration transmission device (1) is provided with a vibrating unit (44), which includes a coil (C) and a contact part (2) for making contact with a contact body, and a magnetic circuit (4), which includes a magnet (41), and the mechanical resonance sharpness value (Qm) is 10 or greater.
