PIEZOELECTRIC VIBRATING DEVICE

摘要

PURPOSE: A piezoelectric vibrating device is provided to prevent a piezoelectric vibrating member from being damaged by including a limiting member to limit the movement range of a weight member. CONSTITUTION: A case has a preset space. A piezoelectric vibrating member is formed in the case. A weight member (400) is connected to a part of the piezoelectric vibrating member. Holes are formed on the preset areas of the case, the piezoelectric vibrating member, and the weight member. A limiting member (500) limits the movement of the weight member.
