xMEMS Achieves Extended Bass Response, Making ANC Applications Possible From a Single MEMS Driver

The new Cypress MEMS speaker from xMEMS Labs achieves 40X louder bass response on a single monolithic, miniaturized device, achieving well above the 130dB SPL at low frequencies, required for ANC implementations on TWS earbuds. The new xMEMS Cypress achieves this groundbreaking performance by using ultrasound technology. The new development will be demonstrated at CES 2024 by appointment only, with mass production scheduled for late-2024.

Nanusens has announced that it has successfully created a fully digital circuit design to measure the capacitance of its nanosensors. This means that both the sensor structure and its detection circuitry can be made at the same time within a chip using standard CMOS processes on whatever process node is required. As a result, ASICs can now be made with several different sensors embedded within them, helping to expand MEMS applications in hearables.

STMicroelectronics, a global semiconductor company that is also a top manufacturer of Micro-Electro-Mechanical Systems (MEMS), announced the launch of its new Intelligent Sensor Processing Unit (ISPU) that combines a Digital Signal Processor (DSP) suited to run AI algorithms and MEMS sensor on the same silicon. By combining signal processing and AI algorithms onto MEMS sensors, ST enables standalone devices that are able to sense, process, and take action, while substantially saving space and power.

Austrian microspeaker company USound has just received an additional equity tranche increasing the last financing round to $30 million. According to the company, these added funds will accelerate the evolution of the next MEMS microspeaker generation, with the potential to boost the battery life of wireless earbuds and other wearable devices up to 12 hours. USound hopes to enable a market transition from electrodynamic drivers to solid-state technology with the next-generation of its Ganymede piezoelectric MEMS.

Microchip Technology announced the industry’s smallest MEMS clock generator, ideal for the development of connected devices and mobile/portable applications. This new device can replace up to three crystals and oscillators on a board, reducing timing component board space by up to 80 percent. The DSC613 clock family eliminates the need for an external crystal by integrating a low-power and high-stability Micro-Electro-Mechanical Systems (MEMS) resonator.
