Tailoring the performance of flexible loudspeakers by varying cell actuator formation

The AVID™ and the ESPI measurement systems were established to obtain the first resonance frequency and the corresponding vibration mode shape of an electret cell actuator. The FEA model was validated by experiment results. The size, form and configuration of an electret cell actuator were confirmed to be the essential factors to be taken into consideration to obtain a good design for good results.
