Zusammenfassung:To provide a soundless alarm (100) of a portable article including electromagnetic motor means (200) capable of being controlled by electric power so as to generate a vibration effect.SOLUTION: In a soundless alarm (100), electromagnetic motor means (200) includes a movable magnetic circuit (210) and a static magnetic circuit (220); the movable magnetic circuit (210) includes a coil (211) and a ferromagnetic core (212) which is magnetically connected to a magnetic cage (213), where the magnetic cage forms an extension part of the ferromagnetic core (212); a magnetic assembly of the movable magnetic circuit (210) constitutes a movable magnetic mass body of the soundless alarm (100) so as to be capable of generating a vibration effect; and the soundless alarm includes an elastic connection element (60) for elastically connecting the movable magnetic circuit (210) to the static magnetic circuit (220), where when the elastic connection element (60) electrically controls the electromagnetic motor means (200), the movable magnetic circuit (210) is processed in shape so as to be guided to reliably receive linear or quasi-linear vibration movement.SELECTED DRAWING: Figure 1 【課題】本発明の一態様は、振動効果を生み出すために電気で制御できる電磁モータ手段(200)を含む携帯型物品の無音アラーム(100)に関する。【解決手段】無音アラーム(100)は、電磁モータ手段(200)が、可動磁気回路(210)および静止磁気回路(220)を含み;可動磁気回路(210)が、コイル(211)と、磁気ケージ(213)に磁気的に連結している強磁性コアであって、磁気ケージが強磁性コア(212)の延長部を形成する、強磁性コア(212)とを含み;可動磁気回路(210)の磁気アセンブリが、振動効果を生み出すことのできる無音アラーム(100)の可動性磁気質量体を構成することと;可動磁気回路(210)を静止磁気回路(220)に弾性接続させる弾性接続要素(60)を含み、弾性接続要素(60)が、電磁モータ手段(200)を電気制御する際に可動磁気回路(210)が線形、または準線形の振動運動を受けるよう案内して確実にするように形状加工されることとを特徴とする。【選択図】 図1
