The present invention relates to a piezoelectric speaker for low frequency compensation. The piezoelectric speaker includes a vibrating plate including first and second copperplates separately prepared on both sides of a resin plate; a signal delivery pattern part prepared on a part of the resin plate to be insulated from the second copperplate of the vibrating plate; a piezoelectric element prepared on an upper part of the second copperplate but receiving a signal through the signal delivery pattern part; and first and second wires separately soldered on a part of the second copperplate and the signal delivery pattern part. A structure of the vibrating plate is formed by forming a resin film, and forming an electrode pattern of copper materials on the surface of the resin film and the structure is formed to apply a frequency signal to the piezoelectric element through the electrode pattern of copper materials so that easy soldering work reduces work time as well as manufacturing costs. |
