Flat "sensor" speakers from Matsushita Electronic for mobiles and PDAs
We´ve recently reported that Matsushita Electric announced new Sound Slim speakers, utilizing horizontal magnetic current created by two repelling magnets. Now the company announced new Sound Window products: flat Acoustic Panel speaker and Acoustic Touch Panel (A-TTP) speaker integrated into a sensor panel.
The technology essence is that Aero Drive speakers utilize thin film, that doesn´t require a hard base to create sound. Moreover, they say that external pressure on such panel will result in volume reduction, as other areas of flexible film will continue to vibrate.
As you know, sound "holes" of current mobiles and PDAs accumulate much dirt and moisture (and microbes :-), so, the idea to combine speakers with LCD protection panels is rather prospective, as it can make any holes in a mobile / PDA obsolete. Matsushita Electric plans to ship its speakers from August and to launch volume production of acoustic panels in March 2003.
