    Abstract: A piezoelectric vibration module includes a vibration plate adapted to have one end fixed and the other end not fixed and driven in a vertical direction based on the fixed first end, a first piezoelectric element attached to the top or bottom of the vibration plate and adapted to generate a vibration power when power is applied, and a weight formed in the other end of the top or bottom of the vibration plate and adapted to control the vibration frequency of the piezoelectric vibration module. The first piezoelectric element is attached to the top or bottom of the vibration plate with a predetermined interval from a fixed point at the one end of the vibration plate.

    Abstract: Provided is a piezoelectric speaker unit to be installed in a mobile terminal. The piezoelectric speaker unit includes a plate, a piezoelectric body attached to a central part of the plate, and an edge type support member which supports one surface of the plate along an edge thereof and provides a space therein in which the plate is deformable. Here, at least one opening, which has one side communicating with the space and the other side communicating with the outside of the support member to release sounds generated in the space by oscillation of the plate to the outside of the support member, is formed in the support member.
