Zusammenfassung:The present invention relates to a piezoelectric vibration module comprising: a vibration plate, the first end of which is fixed, the second end of which is not fixed, and which is driven in the vertical direction with reference to the fixed first end; a first piezoelectric element attached to the upper or lower surface of the vibration plate so as to generate a vibration force in response to application of power; and a counterweight formed on the upper surface of the vibration plate or on a different end of a different surface thereof so as to adjust the vibration frequency of a piezoelectric vibration module, wherein the first piezoelectric element is attached to the upper or lower surface of the vibration plate at a predetermined interval from a fixed point on the first end of the vibration plate. La présente invention concerne un module de vibration piézoélectrique qui comprend : une plaque de vibration, dont la première extrémité est fixée, dont la seconde extrémité n'est pas fixée et qui est entraînée dans la direction verticale par rapport à la première extrémité fixée ; un premier élément piézoélectrique attaché à la surface supérieure ou inférieure de la plaque de vibration de manière à produire une force de vibration en réponse à l'application d'une puissance ; et un contrepoids formé sur la surface supérieure de la plaque de vibration ou sur une extrémité différente d'une surface différente de celle-ci de manière à ajuster la fréquence de vibration d'un module de vibration piézoélectrique, le premier élément piézoélectrique étant attaché à la surface supérieure ou inférieure de la plaque de vibration à un intervalle prédéfini à partir d'un point fixe sur la première extrémité de la plaque de vibration. 본 발명은 일단이 고정되고 타단이 고정되어 있지 않으며, 상기 고정된 일단을 기준으로 수직 방향으로 구동하는 진동 플레이트, 상기 진동 플레이트의 상면 또는 하면에 부착되며, 전원 인가에 따라 진동력이 발생하는 제1 압전 소자, 상기 진동 플레이트의 상면 또는 타면의 타단에 형성되어, 압전 진동 모듈의 진동 주파수를 조절하는 분동을 포함하고, 상기 제1 압전 소자는, 상기 진동 플레이트 일단의 고정점과 기 설정된 간격을 두고 상기 진동 플레이트의 상면 또는 하면에 부착되는 것을 특징으로 하는 압전 진동 모듈에 관한 것이다.
