Mayht speaker driver technology

Mayht New Speaker Driver Technology Attracts Multi-Million Investment | audioXpress

“Our vision is that Mayht will become the new industry standard for speaker driver technology”, says Mattias Scheek, CEO of the company. “The world will get used to - until now unimaginable - high-quality full range sound experiences including the full bass spectrum, from the most compact of form factors.”

We are in the process of developing our Technology Platform which will bring optimal sound quality to any device in all verticals. We are in close contact with the world leading Tech- and Audio companies, and see their interest grow at every step that we take”. Driver technology has so far remained unchanged for at least 75 years. With Mayht it is finally possible to think of radically new and smaller form factors, with immense sound quality improvements - a true paradigm shift. Phones will sound like bluetooth speakers, small bluetooth speakers will sound like hi-fi speakers, a flat TV will finally have home-theater sound capabilities.

Mayht – Disruptive Transducer Technology

- So it is a double opposing diaphragm bipole system, pumping air in-between with high excursion. A woofer really, they don't say how high it can go.

how it works ?

Any idea of its working principle ? Pat number ?...

They described "a distributed motor" and opposite movements of the twin membranes, Controlled high linearity and air pressure compensation (negative compliance)...

Marketing ideas or real improvements ?

Thanks for any info...
 
OK Thanks for the patents...
As I see it's different from the bending waves of NXT and others (Podium, Manger, etc...). Line Array made a good classification of bending waves elsewhere on DIYAudio.

This principle with several drivers on the same membrane is a variation on Teragaki's speakers.

A very funny "ear calibration"(!) of the speakers is shown in this video...

I understand that this "new" loudspeaker improves the "pistonic" motion of the membranes resulting in "better efficiency and power" (sic), but there are several other factors who affect the performances of a loudspeaker. It seems none are addressed in these patents...

With 3 motors per diaphragm, any imbalance among them leads to distortion.

My first thought on seeing these was how do they make a surround and is it like that mysterious Russian ribbon tweeter in which they seem to claim that they figured out how to seal around the moving ribbon?

Miniaturization magicians are the folks who designed such good sound in iPhones and Echoes and the like.
