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. 提供一种安装在移动终端中的压电扬声器单元。该压电扬声器单元包括板、装配到板的中心部分的压电体以及边缘型支撑构件，该边缘型支撑构件沿着板的边缘支撑板的一个表面，并且在其中提供空间，该板可在该空间中变形。其中，在该支撑构件中形成有至少一个开口，该开口的一侧与该空间连通，另一侧与该支撑构件的外部连通，以将通过该板的振动在该空间中产生的声音释放到该支撑构件的外部。
