This study employs physical modeling prototypes for investigating acoustic energy harvesting inside closed-box loudspeaker enclosures via a biomimetic mechanism and a piezoelectric transducer. Test results indicate that the proposed device can generate up to 0.34 mW (0.64 µW/cm2) for Lp = 129 dB and 6.58 mW (256 µW/cm2) for Lp = 159 dB inside a large and a small enclosure respectively (for driving power of 1 W) having also an effect similar to that of absorption material.
