Abstract: A personal alarm which is compact, portable and fashionably designed. In one embodiment, this personal alarm is structurally incorporated into a wrist watch with the alarm components arranged thereon in a fanciful yet highly functional manner. This alarm may also be structurally incorporated into other conventional items such as a bracelet, pendant, necklace, keychain ornament, or any other conventional item which is often carried by the persons to be protected. In a further embodiment, the compact size is achieved without sacrificing intensity in the alarm signal by incorporating a specially wound autotransformer and an efficient switching device so as to provide a tuned warbling signal upon a piezoelectric transducer. Additionally, the alarm may be activated or deactivated by manually actuating an actuator, such as a switch or plurality of switches, in a particular sequence.
