<P>PROBLEM TO BE SOLVED: To vibrate a larger portion of a film material, to which an acoustic vibration body is attached, with vibrations of the acoustic vibration body and enable desired sounds to be emitted from the vibrating film material more effectively. <P>SOLUTION: A filmy speaker includes: a film material 3 having an outer edge part attached to a fixed side member 2; an acoustic vibration body 4 disposed at one part 3a of the film material 3 which is located in the plane direction; and a fixture 5 attached to the one part 3a of the film material 3 and allowing the acoustic vibration body 4 to be attached to the one part 3a of the film material 3. Tensile force T is applied to the film material 3 and the fixture 5, and the one part 3a of the film material 3 and the fixture 5 are pressure welded to the acoustic vibration body 4. <P>COPYRIGHT: (C)2013,JPO&INPIT |
