Parliamo
del ribbon tweeter |
¡¡The
real, natural and attractive sound.
¡¡It has not been difficult today to develop and make the first class
aluminum ribbon tweeters with relative low price because the high
technology enables this old invention to irradiate new life and vigour.
¡¡
¡¡ People had been conquered by their power to play graceful sound since
the aluminum ribbon tweeter was born. Therefore aluminum ribbon tweeters
are adopted in Hi-End loudspeakers.
¡¡Why do aluminum ribbon tweeters have such strong attracting force to
manufacturers and audio fans?In brief, it overcomes many shortcomings
and pities of the dome and the cone tweeter, so they have got very good
technology quality and perfect sound quality.
|
¡¡ Dome and cone tweeters belong to electro-dynamic
loudspeakers together with the aluminum ribbon tweeter, but the
difference is that the diaphragm and the voice coil of the formers are
two separate parts. While they are working with magnet system, firstly
the voice coil with signal cuts the magnetic line of force to create
the driving force, and then drive the diaphragm to move forward and
back. Owning to this working principle and structure, the
amplitude-frequency characteristics and phase-frequency characteristic
are not perfect£¬the frequency response can not be enough wide, the
sensitivity is restrained, the distortion is comparatively big and the
transient characteristic is not good¡¡ Although the aluminum ribbon
tweeter also needs magnet, it combines the voice coil with the
diaphragm cleverly; that is ¬the aluminum ribbon is acted as the
combination of the voice coil and the diaphragm altogether, and the
diaphragm between the magnetic gaps is instigated fully and directly,
so almost no any energy losses in the process from electrical to
mechanical, the mass of the aluminum ribbon diaphragm is comparatively
light ©¤ the diaphragm can not only be driven easily but also be
controlled well |
 |
. Acting force has no phase differences, transform
efficiency is high£¬the frequency response is wide, the distortion is
small and the transient characteristic is good¡¡.
¡¡
¡¡ As the high frequency transducer and radiator of the loudspeakers,
the aluminum ribbon tweeter has the overall and good physical technology
properties. The related transient characteristic is very good in
relation with wide frequency response and small distortion. Not only the
sine wave responses very nice©¤ appears the waveform reverting ability
of the high-fidelity£¬but also the reaction is prompt for the changeful
music signal, specially for percussion and plucked strings music, the
aluminum ribbon tweeter can fully show the impulse characteristic. In
the square wave and tone burst measurements, the wave-front follows well
and the decay has no any delay. It can be said with the important
performance of ¡°high resolution¡±. Furthermore, the overtone is rich,
stirring, exquisite, tender and smooth, and the directivity in front
horizontal of radiating main axis is good ©¤ that is to say, radiation
angle is broad and radiation is symmetrical, and so on.
¡¡Aluminum ribbon tweeter is composed of diaphragm, magnet system,
transformer and other important parts. At present, G series and APR
series aluminum ribbon tweeters of Aurum Cantus use two different kinds
of diaphragm structures. G series use the draped diaphragm and APR
series use the planar hexangular honeycomb diaphragm. Both of them are
hand-made with care by aluminum foil. U-shaped magnet system is one of
the characteristics of Aurum Cantus aluminum ribbon tweeter. This
special magnet system not only makes the B value between the magnetic
gaps up to 5000-6000 gauss, but also can prevent flux leakage. It is
very important to match a precise transformer because the impedance of
full load current of the diaphragm is very small. Lastly, we strongly
recommend not doing the full audio frequency range measurement because
doing that will damage the diaphragm of the aluminum ribbon tweeter
easily. Therefore, we suggest you could use a special filter to decrease
low frequency signal if you really want to do tests
