| Abstract(in English) | We have developed loudspeakers for flexible displays which we can carry with us wherever we go. We made two types of loudspeakers, one consists of polyvinilidene fluoride under the unimorph construction pasted over all the display, the other is with electro-dynamic actuators which vibrate the display directly and generate sound. Both loudspeakers are flexible and transparent, and are able to generate suficient volume as mobile loudspeakers. In this paper, we report the structures of the loudspeakers, and their acoustic characteristics. |
