Merit of AR system ________________ APL. 2018
About 5 years pass after AR-1 is manufactured, and 2 years and a half have been passed from AR-2 planning.
For keeping my original intention, I should order my thoughts from various points of view.
PLS refer the following PDF file.
The feature of AR system
"AR system" is a speaker system of which I conceived by making the "law of action reaction" into a basic principle.
Originally, a sound source is a source of sonic energy and must not be vibrated by a certain disturbance like external force.
In spite of it, in almost all of speaker systems, vibration which the driver generated will vibrate its own frame, and also will vibrate enclosure.
If the intensity and its mass of a floor are enough when enclosure is placed on a floor, it will be fixed to a floor even if it is the excited enclosure.
As a result, the reflection from which the floor became a fixed-end will arise, and finally vibration will return even to a driver.
Since it is a modulation by external force which was originally excited by the driver, it has correlativity.
Therefore, the same phenomenon as auto-intoxication will occur.
When a floor is weakly and vibrates easily , the vibration which got across to enclosure will get across even to a floor, and the cross-modulation resulting from the material of the floor will return to a driver.
Furthermore, the enclosure becomes un-fixed and the standard point of a vibration system becomes indefinite.
Reappearance of an acoustic image is affected as a result.
In order to make influence of a floor into the minimum, a wedge may be installed in the four corners at the bottom of enclosure, but it cannot necessarily escape from cross-modulation.
AR-system copes with such cross-modulation distortion for all of an audible acoustic wave frequency.
In a sub-woofer system, since the amplitude of a diaphragm is large and the influence on the circumference also becomes large, the system which adopted such a cancellation structure is brought to the market.
For example, there are the Giya series of Vivid audio, PV1D of B&W, etc.
However, I do not know the speaker system by which this structure covered all of an audible acoustic wave frequency, and was adopted.
The following makes the outline of AR system a pdf file.
