A mobile phone has a secondary cell, etc. Two film speakers are arranged on the reverse side of a battery holder for accommodating the secondary cell. The film speakers are enclosed by a frame on the periphery thereof, with double-sided tape pasted on the surface-side frame, by which the film speakers are stuck to a speaker holder. The bottom surface of the battery holder is provided with two pressing parts in correspondence to the two film speakers. When these components are assembled into position, the pressing parts are placed in a state of pressing the frame on the reverse side of the film speakers from the reverse side of the film speakers toward the speaker holder, with the film speakers placed in a state of being sandwiched from both the front and reverse sides. |
