Licensor of signal processing platforms and artificial intelligence processors for smarter, connected devices, CEVA, has announced the availability of Dynamic Speaker Management (DSM) software from Maxim Integrated Products for the CEVA-TeakLite-4 family of ultra-low power audio/voice DSPs. The DSM optimised software implementation running on CEVA-TeakLite-4 is already integrated into a smartphone SoC from a Tier-1 smartphone OEM.

Many devices, including smartphones, headsets and wearables encounter significant challenges when it comes to speaker design. The requirement for increasingly smaller micro speakers and the power constrains in these devices severely limits the sound quality possible using conventional D-class amplifiers.

DSM running on the CEVA-TeakLite-4, together with Maxim’s boosted IV sense Class D speaker amplifiers overcomes these challenges, delivering a much richer sound experience with 2.5 times louder sound and two octaves deeper bass versus conventional Class D amplifiers.

Jonathan Chien, Managing Director and General Manager of Audio Solutions at Maxim, said: “At Maxim, we are constantly pushing the boundaries of the sound quality possible from micro speakers, creating louder and richer listening experiences  for our customers.

“DSM on the CEVA-TeakLite-4 DSP is already proven with a tier-1 smartphone OEM, and offers an exceptional solution for any speaker-constrained and power-sensitive mobile device.”
