Claim:
1. An apparatus, comprising: an electromechanical polymer actuator, including an electromechanical polymer layer and electrodes configured to induce an electromechanical response in the electromechanical polymer actuator; a substrate supporting the electromechanical polymer actuator; a mass element supported by the substrate; and a support structure supporting the substrate, wherein the support structure is not integrated with the electromechanical polymer actuator, and wherein the support structure stores an elastic potential energy from deformation and provides tension to the substrate so that the electromechanical response in the electromechanical polymer actuator modifies the tension and induces a vibrational response in the substrate and the mass element, wherein the substrate comprises a flexible film supported at intervals by the support structure, and wherein the vibrational response has a frequency between 100 Hz to 300 Hz.
