Abstract	A newly developed light sensitive, actuator-based, smart polymer loudspeaker is presented. The advantages of this polymer loudspeaker include being lightweight and having the flexibility to be cut into any arbitrary shape or surface to create a versatile audio system for the home or car. This light-sensitive, actuator smart polymer is created using a piezoelectric polymer as the substrate and TiOPc (Titanyl phthalocyanine y-modification) as an additive. The relationship between acoustic impedance, stiffness, and light-sensitive dyes were measured. The effects of light-sensitive dyes on acoustic impedance were measured for decreasing output of sound waves. The influence of acoustic performance on illumination pattern as a modulated distributed force field is examined in detail. The displacement and the acoustic fields produced by the light-sensitive smart polymer actuator were simulated using a finite element method (FEM). The possibilities to further improve the performance of our newly developed micro speaker by adopting psychoacoustics are detailed.
