<p><P>PROBLEM TO BE SOLVED: To provide a performance device with which one can not only enjoy oneself with a performing sound but also enjoy oneself visually by making a sound generation body of the performance device emit light in more inexpensive and simple constitution without needing a power source and various kinds of sensors. <P>SOLUTION: The performance device (for example a Vidro1) according to the present invention is constituted by including the sound generating body (a thin plate-like diaphragm in case of the Vidro) which deforms or vibrates by applying a force to it from outside it to generate sound. The sound generating body has a stress light emitting film (not shown in Fig.) formed with a coating material including a stress light emitting material emitting light according to the applied force, the stress light emitting film emits light as the sound generating body deforms or vibrates to emits sound and light simultaneously. There are a thin plate-like diaphragm, a chord, and a sound board, or the like as the sound generating body. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
