Field presenter application (3)

Here is the concept of UP4D (UnParallel 4-Direction) field presentation loudspeaker system.
There are four drivers in each channel and each driver faces different direction, and height of each driver is different each other.
Left channel and right channel are symmetrical.
First application was pipe resonator system.
Pipe resonator is advantageous to configure slim shape.
This "slim" structure may be the most important factor for field presentation system.
Any way, this one realized unbelievable sound field.

Mechanical Matrix MMX Speaker System

Image
 I noticed that installing speaker drivers both L and R channel to same chamber makes stereo effects more than ten year ago. It was a test model for MCAP-CR application. Primary focus was to verify if thin film bottle could substitute for speaker driver membrane. The answer was "no"; however, it was found thin film bottle can be used as MCAP-CR subchamber. This system has both L and R drivers in the main wood chamber. I was curious about stereo effect, though L and R were installed closely. I recently tested above effect with 8" full-range drivers (photograph below). This model has two (L & R) FE206E frivers in same chamber. Real sound field effect was given by this system in big room. Now let us see the system of electrical matrix speaker system (let us call "EMX" speaker system) below: EMX is electrical wiring system with unbalanced amplifier whose negative terminal is grounded. Balanceed amplifire may not be used for MMX system. Mechanical matrix speaker...

Copied design?

Previous post may have not make readers understand. Here is the story. My site has contacting application to me. This application enable anyone to contact me directly through the web site: http://mcap.webcrow.jp/ . One person gave me information about suspected copy of my design. MCAP-CR is patented in Japan. Though it does not apply to some countries, but my copyright is protected. When I am asked for the use of the patented idea, I always allowed to use for free with the following conditions: Patent information and permission by the patent holder is noted. Indicate the website of the patent holder. Indicate the patent holder's information. Use the manufacturer's original design . I am happy to help manufacturers to give simulation. In this case, copy of my design is suspected without permission of patent or design use. The person who reported to me suspected unauthorised use of MCAP-CR gave me the information of the website. I will be the happiest to auth...

MMX Drawing example

 MMX is abbreviation of Mechanical Matrix loudspeaker system, which was described in the previous blog article. Without hearing an example system, it will be difficult to imagine its sound field. I added sample drawing below: http://mcap-cr.com/mcap/drawings/MMX-2_drawing-set.pdf This system is actually made. I enjoy listening music with this MMX-2.
