Trigence Semiconductor today unveiled the latest demonstration of Digital Speaker Modules (DSMs), providing a blueprint for OEMs, ODMs, and system integrators to incorporate the value of state-of-the-art digitally-driven micro-speakers in Ultrabooks, tablets and smartphones. These ground-breaking DSMs match the performance of the best traditional analog amplifier solutions, while reducing the active power requirement of the audio output stage to as little as 30% of a comparable analog D-Class amplifier driven solution. DSMs both extend battery life and simplify the system-level architecture, requiring routing and consideration of only digital signals, operating from a single 5V supply rail, and needing no high-voltage components in the support circuitry.
By combining Trigence Semiconductor's patented DnoteŽ digital amplifier IC solutions with micro-speakers from
Trigence DnoteŽ technology utilizes specially adapted delta-sigma techniques to overcome manufacturing mismatches in the speaker voice-coils whilst driving only the number of coils necessary to achieve a given dynamic SPL requirement. The result is a high fidelity audio output that consumes as little as 30% of the battery power needed by traditional output stages.
"Power consumption is a huge issue in portable products, with manufacturers looking at every way to optimize battery-life," said
Using DSM's enables OEMs, ODMs and system integrators ignore the complexities of creating a compelling audio experience. The DSMs are simply fed audio data through the most readily available digital format (e.g. I2S), and the DSM takes care of the rest (including audio equalization). DSMs require only a single 5V or higher supply rail, and are independently addressable at the system-level.
Prior to DSMs, system designers were required to develop, test and refine a dedicated audio amplifier and conditioning PCB based on analog D-Class amplifier solutions. These audio boards typically need multiple power rails or boost-supply circuits, and incorporate a mix of expensive high-voltage components. Significant care is needed in the routing and shielding the analog signals on such boards in order to minimize EMI and maintain an acceptable audio experience.
