PROBLEM TO BE SOLVED: To provide a speaker which can be inserted into a thing easily deformed such as a pillow and which can alleviate pain provided to a user. SOLUTION: The first sheet 2 and the second sheet 3 of a speaker 1 are formed of soft sheets. If they are inserted into a pillow or the like, the first sheet 2 and the second sheet 3 are freely deformed and touch a user softly, thereby enabling pain provided to the user to be alleviated. Also, since magnets 4 and 5 are opposed at the same magnet pole, magnetic repulsion f and f in a direction of moving away from each other operates to the first sheet 2 and the second sheet 3, and tensions T and T always operate to the first sheet 2 and the second sheet 3. Accordingly, if a voice signal is provided to a driving coil C, a sound can be emitted from the first sheet 2 and the second sheet 3. COPYRIGHT: (C)2004,JPO&NCIPI
