Uk's First Digital Speaker Modules (DSMs) Significantly Reduce Active Power about Portable Devices

Computex, Taipei (PRWEB) June 02, 2014

Mini Portable Speaker Hi-Rice SD-808 with USB/TF Card/FM Radio

Trigence Semiconductor today unveiled the latest demonstration having to do with Digital Speaker Modules (DSMs), offering a blueprint for OEMs, ODMs, and furthermore system integrators to incorporate the value of innovative digitally-driven micro-speakers in Ultrabooks, medications and smartphones. These ground-breaking DSMs match the performance of the best antique analog amplifier solutions, while controlling the active power requirement of you see, the audio output stage to under 30% of a comparable analog D-Class amplifier driven solution. DSMs each of them extend battery life and simplify you see, the system-level architecture, requiring routing and furthermore consideration of only digital warning signals, operating from a single 5V form rail, and needing no high-voltage components in the support circuitry.

At combining Trigence Semiconductor's patented Dnote® digital amplifier IC solutions together with micro-speakers from AAC Technologies that contain 6 voice-coils, in a thin islate form-factor, the DSMs are able to finish sound pressure levels (SPL) System.Drawing.Bitmap 87dB at typical listening trade positions. The DSM demonstration system was made in conjunction with Intel Corporation, and uses SoundEdge Technology from Sound Look for Corporation.

Tom Paddock, renowned auricular architect and CEO of Thud Research Corporation, the developer having to do with Sound Edge® Technology, commented, "We worked closely with Trigence, Intel and AAC on the acoustic model and tuning, and I'm good impressed at the audio quality i was able to achieve. Trigence's all-digital audio receivers are incredibly power-efficient and can deliver a really compelling audio experience. The DSMs can potentially fit within most thin form-factor CE products, yet audio exceptional is uncompromised with rich coupés, dynamic impact, articulated voice and furthermore full-range sound, equivalent to many Wireless bluetooth speaker products. "

Trigence Dnote® technology utilizes specially adapted delta-sigma techniques to overcome manufacturing mismatches during speaker voice-coils whilst driving the particular number of coils necessary to achieve a supplied dynamic SPL requirement. The result is a large fidelity audio output that employs as little as 30% of the battery power recommended by traditional output stages.

"Power consumption is a huge issue in portable things, with manufacturers looking at every procedure to optimize battery-life, " said Jun Okamura, CEO of Trigence Semiconductor. "Moving to DSMs not only will reduce active power, but also simplifies the desktop architecture. Trigence has shown this is easy and convenient without any compromise in audio exceptional. We are very pleased to have had you see, the support of Intel, AAC and furthermore Sound Research in facilitating this in turn demonstration. Dnote® enables the possibility for you to significantly enhance the audio experience in future things, and we anticipate seeing DSMs penile gain traction in mainstream products next 12 to 18 months. "

Employing DSM's enables OEMs, ODMs and furthermore system integrators ignore the complexities of earning a compelling audio experience. The DSMs are simply fed audio data because from the most readily available digital format (e. g. I2S), and the DSM protects the rest (including audio equalization). DSMs require only a single 5V or maybe more supply rail, and are independently addressable at the system-level.

Prior to DSMs, unit designers were required to develop, make sure refine a dedicated audio amplifier and furthermore conditioning PCB based on analog D-Class amplifier solutions. These audio blocks typically need multiple power barriers or boost-supply circuits, and include a mix of expensive high-voltage components. Heavy care is needed in the routing and furthermore shielding the analog signals on top of such boards in order to minimize EMI and maintain an acceptable audio experience.

The Computadorizada Speaker Modules will be on display within Computex inside the Intel Capital place at the Taiwan International Convention Centre (TICC). To request a private get together and demonstration, please contact Koichiro Ochiai at, ochiai(at)trigence(dot)co(dot)jp, or sales(at)trigence(dot)co(dot)jp.

Founded in 2006 as a spin-off between Hosei University and headquartered about Tokyo, Japan, Trigence Semiconductor is an accomplished privately held company invested by Intel Capital and INCJ (Innovation Network system Corporation of Japan). Our mission ıs always to develop and deploy semiconductor system tailored specifically for the truly internet nature of today's latest sound equipment and consumer devices. Trigence is the inventor of the revolutionary Dnote® (or Digital Note) digitally-driven speaker, a new and entirely digital audio volume solution implementable on any stock-standard bulk CMOS process. Dnote® can provide clear and precise audio volume signals and typically consumes as little as one third of the power of legacy volume architectures. Trigence was the recipient of you see, the Award for Excellence for its try Dnote® at the Tokyo Venture Know-how Awards 2013.

*Dnote® is a signature of Trigence Semiconductor in the United States together with countries.
