dc.description.abstract | We fabricated a textile speaker using polyvinylidene fluoride (PVDF) as the vibration film with a z-axis oriented ZnO nanopillar. The ZnO nanopillar enhanced the piezoelectricity and the vibration zone under the vibration film. Compared with other piezoelectric acoustic devices, the ZnO nanopillar textile speaker has a higher sensitivity with a larger output acoustic pressure for the speaker. The sound pressure level (SPL) of the fabricated textile electrode speaker was measured with the variation of sine wave input frequency and compared to that of the PVDF speaker. The largest SPL of the PVDF/ZnO/PEDDOT:PSS speaker was about 69.7 dB at the input voltage of 6 V peak-to-peak, which was measured at the distance of 5 cm from the textile electrode speaker in an open field. The performance of the PVDF/ZnO nanopillar/PEDOT: PSS speaker increased to 20 dB (SPL) more than that of the PVDF speaker at middle range, as characterized from the Laser Scanning Vibrometer results. | - |
