Matrix transducer for planar headphones
A new patent is published.
The peculiarity of this design is the matrix principle (related to the Trion model), but due to a special magnetic assembly, the sensitivity of such a transducer is 8-10 dB higher than can be obtained with magnets of the same cross section and neodymium type, which makes them promising for use in various portable wireless devices, as well as together with low-power amplifiers (for example, in smartphones or inexpensive players).
Yes, that would be a real 100+ dB/mW. Due to limited resources we cannot afford the pleasure of releasing new models based on this technology on our own, although we already have demonstration prototypes.
Therefore, we invite potential partners to discuss cooperation in this area.
