| The car stereo is an integral part of the entertainment and communications
system in today’s vehicles. Many car entertainment systems have
excellent quality speakers and amps so users can enjoy the latest
news, listen to their favorite music, and even listen to their favorite
books with optimal quality. With car electronics moving more and more
toward integrated systems, it is then a natural extension to take
advantage of these optimized equipment and also conduct hands-free
phone conversations through the car stereo. Fortemedia’s SAM
technology enables the world’s first flat-surface integrated
car stereo speakerphone with echo cancellation and noise suppression.
Seamless Integration
Fortemedia’s SAM technology and products allow designers
to seamlessly integrate an array microphone and speakerphone into
a car stereo, both functionally and aesthetically.
The world’s first flat-surface small array microphone allows
system designers to blend dual beam-forming microphones into the
face of the car stereo and eliminate unsightly microphones pointing
out toward the user. By connecting a cellular phone to the car stereo
speakerphone wirelessly through Bluetooth, the driver can now be
heard loud and clear with both hands on the wheel, as shown in Figure
1.

Time to Market Advantage with Fortemedia
Fortemedia SAM products provide the industry’s best echo-cancellation
and noise suppression performance. Combined with the beam-forming
effect of the small array microphone, Fortemedia products eliminate
stringent requirements of accounting for different acoustic environments
in different car models, microphone characteristics, and placement
of the microphone. This can reduce the development cycles by at
least 50%, giving Fortemedia customers a huge time to market advantage.
Designers now have unmatched flexibility in the system design and
can build the same car stereo for both factory build-in or for the
aftermarket.
Voice Command Recognition
Fortemedia SAM products offer the capability of built-in voice command recognition
and voice key pad control. This feature allows end users to dial
numbers on their cellular phone keypads without having to actually
reach for the cellular phone itself, providing for a true hands-free
experience.
