Abstract
A radio wave receiving signaling device includes an antenna (22) having a coil (22a). An electrically capacitive buzzer (21) is activated by alarm output device (AO) to generate sound when the receiving antenna (22) receives a sound generation instructing signal. The buzzer (21) and all or part of the coil (22a) of the receiving antenna (22) are connected to form a booster circuit to raise a voltage to be applied to the buzzer (21) by a resonance function.
