The aramid hybrid honey cam diaphragm which adopted
the aramid hybrid FRP as the front skin low-pass, and adopted the cellulose
fiber system skin as the back skin is used.
The aramid hybrid FRP makes the
Intra ply structure weave in and carry out hybrid weaving of the amorphous
silica with high rigidity to aramid cellulose material.
cellulose fiber system skin is the skin material excellent in the internal loss.
High rigidity and a moderate internal loss are realized by making these two
diaphragm materials into honeycomb structure.
Moreover, the rigid
outstanding R.S. frame is adopted as a frame.
High order former balance
of high rigidity and a loss factor is aimed at by hybrid weaving of an inorganic
fiber and PAN system quantity intensity carbon fiber which has an organic fiber
aramid and a high specific modulus in the diaphragm of an inside region.
moreover -- giving surface-preparation processing at titanium to a center
diaphragm -- a high ratio -- the S.R. titanium dome with elasticity is adopted.
Furthermore, the high rigidity R.S. frame is adopted as a frame.
boron D.U.D. dome which has also adopted the higher rank model is carried in the
The Tran Gent characteristic, high region threshold frequency, a linearity, input-proof nature, etc. are raised with the D.U.D. structure which
unified the boron with a high physical-properties value, and a diaphragm and a
voice coil bobbin.
Moreover, in order to use low carbon mild-steel material and to decrease
a vibration of the material so that the D.M. system of hybrid construction
may be adopted and a magnetic property may be satisfied on a plate, the
whole plate is covered by the aluminum alloy casting.
The network has
prevented muddiness of sound as 2 division structures, in order to lose the
mutual intervention of elements.
Moreover, a lamination Orient core is used
for a coil and the oxygen-free-copper line is used for wiring.
distributed vibration type enclosure developed uniquely was used for the
enclosure, and 4 side round baffle which made it go around [ both sides and an
up-and-down side ] further is used for it.
