Based on DS-73D, it is a speaker system carrying a magnetic-shield design
or AV equalizer.
The 32cm corn type Woofer which
adopted the poly craft honey cam corn is carried in low-pass.
joined the skin material which carried out impregnation of the craft honeycomb
core using the honey cam (beehive) structure used for an artificial satellite
etc. as a thing excellent in rigidity, and the special resin with polyamide
system adhesives, and has realized the outstanding specific modulus of about 4
times of paper. Moreover, examination is added also to resin and the internal
loss is also going up 20% compared with paper.
The 10cm corn type
squawker which used the CEP (carbon fiber reinforced plastic) corn is carried in
the inside region.
A CEP corn adds and strengthens a rigid high carbon fiber
in big polypropylene of an internal loss, is what was molded by original molding
technology, and is aiming at the inside region play with high density by ohm
titanium cap or adoption of the Than Gen Shal edge.
The 2.5cm dome shape
tweeter is carried in the high region.
The D.U.D. structure which united the
diaphragm and the voice coil bobbin with the diaphragm, and improved the
high-speed response was adopted, and ohm titanium which carried out
hard-facing processing of the titanium diaphragm in special atmosphere is
adopted as a material.
In order to cope with the leakage flux of the
speaker which has a bad influence on the screen of a CRT-television, a magnetic
flow is analyzed by computer and the formal magnetic-shield design which
equipped the magnetic circuit with the magnet for magnetic shields is performed.
Moreover, the bad influence which the magnetism of television has on the
network circuit of a speaker is also taken into consideration, and examination
is added also in the position and direction of a coil of network.
order to reproduce visual software by the optimal sound quality in addition to
the usual HiFi play, the sound quality compensation function corresponding to AV
(AV equalizer) is prepared.
Sealing structure is adopted as the
