A piezoelectric polymer speaker is provided to minimize the limitation of a speaker installation space by installing a piezoelectric polymer vibrator on a specific frame with a receiving space. A piezoelectric polymer speaker includes a piezoelectric polymer vibrator, and a frame(20). The piezoelectric polymer vibrator has a piezoelectric polymer film(11), a conductive polymer electrode layer(12), and two electrodes(13). The piezoelectric polymer film(11) of a circular shape has a predetermined thickness. The conductive polymer electrode layer(12) is coated on a main surface except edge parts of an upper plane and a lower plane of the piezoelectric polymer film(11). The two electrodes(13) are installed on the edge parts of the upper plane and the lower plane of the piezoelectric polymer film(11). The piezoelectric polymer vibrator is fixedly installed on the frame(20) which has a speaker terminal(22) and a plurality of speaker fixing holes(21) on a side thereof. |
