Fujitsu announced they have chosen to use Akustica’s AKU2000 microphones for the embedded microphone array in their LifeBook T4215 Tablet PC. The AKU2000 is believed to be the world’s first Complementary Metal Oxide Semiconductor (CMOS) microelectromechanical systems (MEMS) microphone.
Fujitsu selected Akustica’s microphone chips for a variety of reasons. One reason is that the AKU2000 is a complete Voice-to-Bits audio solution, which is immune to Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) from nearby sources. The small size of the AKU2000 microphones is important as well because they can be embedded in the bezel of the Fujitsu Tablet alongside the LCD. Since the AKU2000 is a CMOS MEMS chip, it can be manufactured in quantity with guaranteed uniformity, which is important because this lets the LifeBook T4215 use noise suppression software in conjunction with the microphone array. "These digital microphones like Akustica’s are becoming increasingly critical in laptop designs because they dramatically improve the quality of voice input, therefore improving the performance of VoIP and other voice-enabled applications,” said Rob Enderle, Principal Analyst, Enderle Group.
"High-quality voice recording is becoming essential to mobile users as they rely more on their Tablet PC to conduct their day-to-day tasks," said Paul Moore, Sr. Director of Mobile Product Marketing, Fujitsu Computer Systems. The ultra-light 4.3-pound LifeBook T4215 Tablet PC is designed to meet the needs of mobile and field professionals who require the flexibility of a tablet for notetaking or navigating through form-based applications, while still having the traditional keyboard input of a notebook computer. It also has the high-performance, power-efficient Intel Core 2 Duo Processor, is Windows Vista-capable and is the only convertible Tablet PC on the market with a built-in modular bay that supports an optical drive or an additional battery. The LifeBook T4215 Tablet is perfect for a wide variety of users.
