Film speaker
is using a piezoelectric film which called PVDF
(Poly Vinylidene Fluoride).
It is thin, minimized, and flexible.
It has also wide frequency and dynamic band, low
impedance, high induced electricity and mechanism,
low density,
and high sensitivity. Its sound impedance is 2.6
times greater than water, human tissue, organics
and 11 times
greater than piezoelectric ceramics.
PVDF’s surface energy is 22.6, 36.5 dyne/cm which
is low. It is hard to connect electric field. We
have surface
reforming, supporting structure control technology
and using Pedot, CNT to overcome low adhesive strength
and the low and middle registers. |
