FAL drivers have been developed to match the HEIL Air Motion TransformerTM mid and high range driver units.
The area of the diaphragm was determined by aiming perfect reproduction of especially well balanced low and mid range.- Use of a flat diaphragm was to solve various
long unsolved problems peculiar to conventional cone diaphragm which had different sound generating points from the center over the outer skirt causing phase
shifts, resultant distortion, and problems of directionality and impedance
Matsushita Electric Industrial Co., Ltd. has developed a transparent panel speaker called "Sound
Window" an industry-first speaker that reproduces sound by pneumatically vibrating a transparent panel using
aerodynamic-drive technology. Featuring extremely low power consumption and design flexibility that makes it
possible to mount the panel speaker onto a display screen or touch panel, "Sound Window" can be applied to a
wide variety of small products such as mobile phones and personal digital assistants.
(1) The "aerodynamic drive technology" acoustically vibrates a transparent panel using the sound pressure generated
by a driver installed in the space behind the panel. This technology ensures sound-pressure transmission to the entire
panel surface, resulting in great flexibility in choosing the installation position of the driver and designing the panel
The Multi–Cell MicroTransducer
The MCMA incorporates dozens
of powerful, Neodymium magnets are aligned on a slender template, above
which a thin, high - temperature film diaphragm is suspended parallel to
the surface of the magnets. On the surface of the diaphragm are
conductive, spiral voice coil circuits, enabling a high degree of
magnetic coupling - and hence low distortion.
