摘要： 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.
摘要翻译： 一个紧凑，便携和时尚设计的个人报警器。 在一个实施例中，该个人报警器被结构地结合到手表中，其中报警组件以奇特但高度功能的方式布置在其上。 这种报警器也可以结构地结合到诸如手镯，吊坠，项链，钥匙扣装饰品或通常被被保护人携带的任何其它常规物品的其它常规物品中。 在另一个实施例中，通过结合特别缠绕的自耦变压器和有效的开关装置来实现紧凑尺寸而不牺牲报警信号中的强度，以便在压电换能器上提供调谐的加速信号。 此外，可以通过以特定顺序手动致动诸如开关或多个开关的致动器来激活或去激活警报。

摘要： A personal alarm which can be manually actuated to produce a high-intensity sonic alarm signal, and 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.
