MULTI-SIDES FILM SPEAKER AND SOUNDS APPARATUS THEREOF

摘要

A multi-sides film speaker and a manufacturing method thereof output an sound effect with high quality by mixing different sound effects according to the polymer conductive layers with different sizes into one through one film speaker. A piezoelectric element film(100) vibrates mechanically according to the inputted voltage. At least one piezoelectric element film is formed by being coated on both surfaces of a piezoelectric element film and has a different size. An electrode is formed by being extended along the frame of each polymer conductive layer(102a,102b,102c). A terminal is formed by being extended from each electrode(104) to the outer side of each polymer conductive layer. The polymer conductive layer is formed to be separated from the inner side of the frame of the piezoelectric element film with a predetermined distance.
