摘要:A device comprises a vibration generator having a magnetic circuit composed of a permanent magnet and a coil, and a diaphragm drivable by the magnetic circuit and secured to a fixed member so as to mechanically resonate at a frequency of f1, a signal generating circuit for producing a signal having the frequency of f1, a filter for blocking the frequency of f1, and selection means. The selection means operates to give notice to the user by applying the signal containing the frequency of f1 and generated by the signal generating circuit to the coil, or to deliver incoming speech to the user by applying a voice signal to the coil via the filter.
