The book shelf type speaker system which adopted the hard dome unit of original
development in order to correspond to new generation sauce including PCM sauce.
The 31cm corn type Woofer is carried in low-pass.
The corn by the new process which blended the paper bush and needle-leaf
tree of the department of a fragrant daphne is adopted as corn paper, and
the waist has realized the diaphragm which was strongly rich in elasticity.
Furthermore, the edgewise volume of
the large caliber which uses a copper streamlined wire is adopted as a voice
coil, and heat-resistant improvement and low distortion-ization are attained.
Moreover, the ferrite magnet is adopted as a magnetic circuit.
hard dome shape squawker is carried in the inside region.
In order to
realize the broadband characteristic, the diaphragm was completed by the process
original with a Coral, and the Mg-Cu addition super-hard light-alloy diaphragm
is adopted as it. In this diaphragm, hardness of 3 times or more and shearing
strength are realized compared with the conventional super duralumin diaphragm.
Impregnation of the resin was carried out to edge, and also the Than Gen
Shal edge which coated the resin in which character differs and was heat-treated
was adopted, and the braking effect and form maintenance capability for pulling
out the characteristic of a super-hard light-alloy diaphragm have been acquired.
Furthermore, in order to perform the relation with a Woofer smoothly, the
back cavity was filled up with the sound-absorbing material, and low fo (280Hz)
is secured. Moreover, the high precision equalizer was formed in the front of a
diaphragm, an improvement of directional characteristics and disorder of the
frequency response produced out of a zone were lost, and the relation with a
tweeter has also improved.
The large-sized ferrite magnet is adopted as the
edgewise volume of the aluminum wire use by the large caliber of 70mmphi, and a
magnetic circuit at the voice coil.
The 3.6cm hard dome shape tweeter is
carried in the high region.
Taking in a super-hard metal by an original
process like a squawker to a diaphragm, edge is a diaphragm and the Than Gen
Shal edge of integral moulding. This pressed down unnecessary resonance and the
Tran Gent characteristic is improved.
Furthermore, interference distortion
is made to reduce with a highly precise equalizer, and improvement in
directional characteristics is aimed at.
The optimal constant is adopted
as the determination of the constant of a network part by not only the check of
an electrical property but the cut and try which thought the hearing as
Furthermore, in order to demonstrate the transient response
characteristic of each unit, the coil containing a lamination core of the
magnetic material selected carefully is used for a metallized film capacitor and
a coil at the capacitor.
Furthermore, the cord of 50 cores is adopted as
The high-density chipboard of special edition is
adopted as the enclosure as an object for audios, and resonance is controlled by
performing reinforcement processing to the key point.
Moreover, finishing is
