World’s First Digital Speaker Modules (DSMs) Significantly Reduce Active Power in Portable Devices

By combining Trigence Semiconductor’s patented Dnote® digital amplifier IC solutions with micro-speakers from AAC Technologies containing 6 voice-coils, in a thin tablet form-factor, the DSMs are able to achieve sound pressure levels (SPL) exceeding 87dB at typical listening positions. The DSM demonstration system was developed in conjunction with Intel Corporation, and incorporates [Reality Amplifier®] from Sound Research Corporation. Tom Paddock, renowned acoustic architect and CEO of Sound Research Corporation, the developer of [Reality Amplifier] Technology, commented, “We worked closely with Trigence, Intel and AAC on the acoustic design and tuning, and I’m very impressed at the audio quality we were able to achieve. Trigence’s all-digital amplifiers are incredibly power-efficient and can deliver a truly compelling audio experience. The DSMs are able to fit within most thin form-factor CE products, yet audio quality is uncompromised with rich bass, dynamic impact, articulated voice and full-range sound, equivalent to many Bluetooth speaker products.”
