The Dynamic Speaker Management (DSM) software from Maxim Integrated has been ported and optimised to efficiently run on Cadence Tensilica HiFi Audio/Voice DSPs. Designers are typically faced with inherent problems, including weak sound and lack of bass response within micro speakers. In addition, they can easily break and produce distorted sound. Maxim’s technology balances bigger sound and better sound quality with lower power and improved reliability against the increasingly smaller size of micro speakers available in the market today.

Maxim’s DSM technology vastly improves audio performance in the following ways:

Enriched bass and added ability to preserve stereo image;
Maximum protection through voice coil thermal protection and excursion limiting;
Voice interoperability compatible with speakerphone AEC; and
A low-cost solution that minimises hardware DSP redundancy.

The Tensilica HiFi DSP is the most widely used licensable audio/voice/speech DSP family, with support for over 160 proven audio/voice software packages and over 75 software partners in the Tensilica Xtensions partner programme.

Jonathan Chien, Executive Director, Business Management, Maxim Integrated, commented: “Our patented DSM software in conjunction with our high-efficiency Boosted IV Sense Class D audio amplifier enables bigger sound, better sound quality, reduced power and improved reliability for micro speakers. We utilise the HiFi DSP found in many mobile devices to efficiently run the DSM algorithm, providing OEMs with a complete audio solution.”

“Maxim develops high-quality solutions that can elevate the audio experience of mobile and wearable devices. Many of our mobile OEM and semiconductor customers are integrating Maxim’s DSM technology with our proven HiFi DSP cores to provide excellent sound quality and increased reliability with the micro speakers that are popular in today’s wearable- and mobile-driven marketplace,” added Larry Przywara, Group Director, Audio/Voice IP Marketing, Cadence.
