PURPOSE: An electrode connection member and film type speaker are provided to reduce the number of terminal processing steps by using a Y shaped electrode connection member which is made of an FPCB(flexible printed circuit board). CONSTITUTION: A film type speaker(100) comprises a piezoelectric film(102), an upper conductive film, a lower conductive film, upper and lower electrodes, and an electrode connection member(200). The piezoelectric film outputs a sound corresponding to a voltage according to an inputted voltage. The upper conductive film and the lower conductive film are formed on the upper and lower surfaces of the piezoelectric film. The upper and lower electrodes are expanded along with the girth of the upper and lower conductive films. The electrode connection member is connected to the upper and lower electrodes. The piezoelectric film uses the inverse piezoelectric phenomenon of a piezoelectric element. |
