Abstract
An organic, ultrathin, and transparent sound-emitting device was fabricated using poly(3,4-ethylenedioxythiophene):poly(styrenesulfonic) (PEDOT:PSS) films. This sound-emitting device was easily processed by spin coating. Sound emission from PEDOT:PSS was measured as a function of power, distance, and frequency. The sound frequency spectrum was found to be ultra-flat in a wide sound frequency range (10–45 kHz). Theoretical analysis showed that the working principle was the thermoacoustic effect. The PEDOT:PSS sound-emitting device has potential applications in the acoustic field. In particular, it can be integrated with a liquid crystal display to realize sound emission and image display at the same time.This publication has 18 references indexed in Scilit:
