Dynamic Speaker Management (DSM) smart amplifiers are an audio solution that combines high-performance current and voltage (IV) sense amplifiers with our patented DSM algorithm to create louder and richer sound from micro speakers. The DSM’s tiny, ultra-efficient boosted audio amplifiers are a great fit for compact products like smart home IoT, portable industrial/medical devices, and gaming. DSM smart amplifiers enable up to a 2.5x increase in loudness (sound pressure level) for micro speakers while significantly improving bass response.

How Does DSM Work?

DSM smart amplifiers utilize current and voltage (IV) feedback and integrate our proven patented DSM speaker protection algorithm within a fixed DSP function. No extra programming is required! This minimizes time to market and reduces design resource overhead. The patented DSM algorithm and IV feedback enable DSM smart amplifiers to push maximum loudness and bass response without exceeding the micro speaker’s excursion or thermal limits. This extra protection leads to louder sound that is clearer and comes with industry-leading low-power consumption.

Is DSM a Fit for My System?

What is a micro speaker? Micro speakers are basically smaller versions of a standard speaker. They usually have a rated power specification from 1W to 2W and a diaphragm area of 1cm2 to 2.5cm2.

Micro speakers either have a small case specifically designed for the driver (an enclosure) or have no case (bare driver). DSM offers the most bass improvement when the front sound waves are isolated from the rear waves, usually with an enclosure. Regardless of the micro speaker design, the patented Perceptual Power Reduction (PPR) algorithm dynamically filters content and volume levels, saving up to an additional 25% of power without a perceptible change in audio fidelity.
