description | 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. |
