明。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a low-frequency vibration to a person, such as a wristwatch or a mobile communication device (mobile phone), in place of sound notification to make another person hear unpleasant sound. An invention relating to a vibration alarm that allows the wearer to sense without having to do so.

問題点があった。As shown in FIG. 1, there is a vibration motor alarm of a mechanism for generating vibration felt on the body by rotating an eccentric weight as a vibration alarm, but it is said that the size is too large or the casing becomes large. There is a problem,
Further, in the type using a magnet to rotate the weight, there is a problem that a mechanism design considering the influence of the magnetization is required.
【０００４】そして、電磁石で振動を発生させるタイプ

【問題を解決するための手段】本発明の振動アラーム
は、圧電素子、ベース、スペーサ１、スペーサ２、重り
から構成され、磁石等を使用しない。The vibration alarm of the present invention comprises a piezoelectric element, a base, a spacer 1, a spacer 2, and a weight, and does not use a magnet or the like.
【０００７】図２の構造により薄型でも圧電素子可動部
先端に比較的大きな重量の重りを乗せることが可能であ

きる構造となっており、これにより強い振動を発生する
ことが可能となる。The structure shown in FIG. 2 enables a relatively large weight to be placed on the tip of the movable portion of the piezoelectric element even when the piezoelectric element is thin, and has a structure capable of maximally utilizing the vibration of the piezoelectric element as the vibration source. Thus, a strong vibration can be generated.

ーサ２、その上に重りを接着した構造になっている。DESCRIPTION OF THE PREFERRED EMBODIMENTS The vibration alarm of the present invention has a structure in which a spacer 1 is provided on a base, a piezoelectric element is provided thereon, a spacer 2 is provided on a tip of the piezoelectric element, and a weight is provided thereon.
【０００９】スペーサ１に接着されたベースと圧電素子
は固定点となり、スペーサ２に接着された圧電素子先端
と重りが可動部となる。The base and the piezoelectric element adhered to the spacer 1 are fixed points, and the tip and weight of the piezoelectric element adhered to the spacer 2 are movable parts.
【００１０】圧電素子の電極部に電圧を印可すると、印

上下し振動を発生、これが固定点のベースに伝わり、ベ
ースに接着した筐体全体を振動させる。When a voltage is applied to the electrode portion of the piezoelectric element, the piezoelectric element warps in accordance with the applied voltage, the weight rises and falls when an AC voltage is applied, and vibration is generated. The vibration is transmitted to a base at a fixed point and is adhered to the base. Vibrates the whole.

【発明の効果】本発明の振動アラームは、腕時計の振動
アラームとして使うことができ、移動体通信機（携帯電
話）の呼出しアラームとしても使うことができる。The vibration alarm of the present invention can be used as a vibration alarm of a wristwatch and also as a call alarm of a mobile communication device (mobile phone).
【００１２】本発明の、圧電素子の振動を利用して作ら
れた振動アラームは、スペース的に振動アラームの設計
制限を大幅に縮小できる。According to the vibration alarm of the present invention, which is produced by utilizing the vibration of the piezoelectric element, the design limitation of the vibration alarm can be greatly reduced in terms of space.
