Patent ID: 7880592

Claim:
Incoming call notification equipment comprising: a signal generation source having a mixed signal output terminal for which a melody generation signal is mixed with a vibration signal that varies at least one of a signal voltage, frequency and period of impression; an electromagnetic induction actuator electrically connected to the mixed signal output terminal which produces melody and vibration, without a feedback signal provided to the output terminal of the signal generation source, the electromagnetic induction actuator having a mechanical vibration system and a diaphragm; a magnetic circuit including a magnet, a yoke, and a pole piece, with the mechanical vibration system including the magnetic circuit that is flexibly supported by a suspension spring; and a voice coil attached to the diaphragm, wherein the diaphragm is vibrated by the melody generation signal, and the melody is produced by vibration of the diaphragm, and at least one of the signal voltage, frequency and period of impression of the vibration signal is varied in accordance with a note of the melody of the melody generation signal, and wherein the range of frequency variation of the vibration signal is set in accordance with a resonant frequency range of the mechanical vibration system of the electromagnetic induction actuator.
