Commonly, audio amplifiers have a couple of drawbacks, size and heat buildup
(namely, poor efficiency). As you know, HDD and Optical-pickup are so vulnerable
to the heat buildup which may cause some irregularity on a variety of applications
(products) in use. It is our main subject to eliminate these drawbacks from
an amplifier, more specifically to minimize the heat buildup therein while
increasing performance/efficiency and output in spite of drastic miniaturization.
The first key to success (KTS) in the recent epoch-making developmental
efforts is that we are able to develop, engineer and evaluate both technologies
of power supply and amplifier, regardless of whether they are analog or digital
The second key is that as detailed below, a number of technologies
for miniaturization were newly developed.
Our final goal to our recent project was to oust "power amplifier" from
the audio system.
A large-output and high tone quality speaker will suffice for
its original purpose even if "power amplifier" does not exist physically.
Besides technological development, equally important is product's
We, therefore, consigned appropriate designing to this innovative
product, to GK Industrial Design Corporation which leads the Japan's industrial
designers' world. Poor designing will spoil the quality of product no matter
how technically excellent it may be.
Last but not least, as may be understood from the applications
enumerated below, for our future's candidates, these technologies will be
applicable to the whole field of power electronics. Therefore, our strenuous
efforts will be made along this line.
