Unleash the Full Potential of Your Micro Speakers

By: Reno Rossetti, Michael Tuason and Greg Mow


This design solution discusses the barriers to high-quality sound from micro speakers due to their size limitations. Maxim's Dynamic Speaker Management Sound Studio GUI overcomes these barriers, simplifying design and improving time to market. The DSM algorithm is integrated into a fixed-function DSP to alleviate the complexities of programming. DSM, based on MAX98390 Class DG audio amplifier, significantly increases loudness (SPL) and bass response from micro speakers while maximizing efficiency for longer battery operation.
