The present invention relates to a piezoelectric speaker capable of reducing a size thereof and minimizing a short of an electrode due to a vibration by forming an electrode with a circuit pattern. The piezoelectric speaker includes a sound diaphragm, a frame which is attached to surround the sound diaphragm, one pair of pattern electrodes which are formed on the upper side of the sound diaphragm with the circuit pattern and apply an electric signal, at least two connection terminals which are flatly attached on the upper side of the pattern electrode and are made of conductive materials, and a piezoelectric layer which is attached on the upper side of the connection terminal and outputs a sound by converting the electric signal applied through the pattern electrode into the vibration. |
