Fortemedia says that its Small Array Microphone (SAM) has been adopted for DoCoMo's 3G Raku Raku PHONE III (FOMA F882iES) handset that is manufactured by Fujitsu. The Raku Raku PHONE III will interest anyone who has ever had to make a phone call in a noisy environment such as a train station airport restaurant or even on the side of the street.SAM Beam forming in a Handheld Device
Together with Fujitsu and Fortemedia, DoCoMo's FOMA Raku-Raku PHONE III aims to solve these annoying problems by applying the patented Small Array Microphone (SAM) technology to create Beamforming, which suppresses undesired noise such as traffic noise, public broadcasts and conversational din by 20 dB. Furthermore, to enhance the intelligibility and the clarity of mobile phone conversations, FOMA Raku-Raku PHONE III first uses SAM to measure noise level of the user's environment, and then uses HAKKIRI VOICE (Clear Voice) Technology to improve voice quality for clear voice communication.
With SAM, microphones can be placed 5mm apart center to center, providing designers and manufacturers plenty of flexibility to find the ideal placement. A cone shaped beam is also formed; with no back leakage and an effective 3-D cone-shaped beam, SAM can cancel out all ambient noise, accurately identifying the sound source and clearly delivering that signal to the computer. Users can now enjoy clear conversations over VoIP and a true full-duplex speakerphone capability.
Dr. Paul Huang, Chairman and CEO of Fortemedia, said, ''DoCoMo has been leading the mobile communications market by offering innovative products and services for its customers; we are excited by the fruits of working with the Fujitsu engineering team to create this visionary product. This is one of the most significant breakthroughs in microphone architecture and telephony performance history in the last 130 years.''
DoCoMo will start to sell FOMA Raku-Raku PHONE III for its Japanese 3G FOMA service subscribers in early September 2006."
