What is billed as the world’s first monolithic true MEMS speaker is just one millimeter thick and is said to deliver high fidelity, full-bandwidth sound and low total harmonic distortion (THD) for sealed in-ear personal audio devices, including true wireless stereo (TWS) earbuds. Called Montara by its creator xMEMS Labs in Los Altos, Calif., the […]

Gasket material suppresses signal interference, reduces force on sensitive electronic components
As design engineers create smaller and more powerful electronics, they must place sensitive components closer together, which can increase to damaging levels the force placed on these components. A new fabric-over-foam gasket from Laird Performance Materials features a soft silicone foam core with a low compression force that suppresses electromagnetic interference without damaging sensitive components. The EcoTemp […]
Speaker line simplifies design integration from prototype to production
CUI Devices’ HYPERLINK Audio Group today announced the introduction of a new line of enclosed speakers designed to maximize performance and simplify design integration from prototype to production. Available in rectangular or round frame shapes with profiles as low as 4.87 mm, the HYPERLINK CES series carries sound pressure levels (SPLs) from 89 to 104 […]
Voice ADC excels at far-field audio
Texas Instruments introduced a new audio analog-to-digital converter (ADC) capable of capturing clear audio up to four times farther away than competing devices. The TLV320ADC5140 is the industry’s smallest quad-channel audio ADC with this level of performance. The device is part of a new family of three TI Burr-Brown audio ADCs that enable low-distortion audio […]

Infineon’s enhanced design and production standards deliver extreme reliability and stability for the entire product lifetime. The new range offers improved power efficiency, […]
USB Type-C port switch enables mobile devices to support legacy data and audio signals
Diodes Incorporated announced the PI3A6386 USB Type-C multimedia port switch, designed to enable manufacturers to continue supporting legacy data and analog peripherals through USB Type-C ports. As a result of the adoption of USB Type-C ports in mobile phones and tablets, manufacturers are removing other ports such as USB 2.0 and 3.5mm audio sockets. The […]
24 MP image sensors enable hi-res front- and rear-facing cameras
OmniVision Technologies, Inc. announced the second generation of its 0.9 micron, 1/2.83-inch optical format 24 MP image sensors, built on the PureCel Plus stacked die technology. The OV24B sensor family is designed for high-resolution front- and rear-facing smartphone cameras. The new image sensor family is available in four versions: OV24B1Q: 4-cell Bayer imaging; in-pixel binning […]
High fidelity audio apps excel with MUS-IC D/A converters
ROHM has launched a new branding “MUS-IC” reflecting ROHM’s focus on solutions for high-fidelity audio products. This branding covers a range of D/A converter ICs (DAC ICs), optimized for high-fidelity reproduction, and power supply products. The increased adoption of high-resolution audio sources has lately strengthened the demand for audio equipment that can deliver an appropriate sound […]
Filters suppress noise from 600 MHz to 2.7 GHz on audio lines
TDK Corporation has expanded the MAF1005G series of noise suppression filters for audio lines with four new MAF1005GAD-D types, which, thanks to their low DC resistance, feature a high rated current of up to 1.25 A. The new types employ TDK’s proprietary low-distortion ferrite that enables the new components to suppress noise at cellular frequencies from […]
Active noise cancellation, Part 2: Implementation
Part 1 of this FAQ looked at the basic concept of active noise cancellation, how it might be implemented in principle using analog circuitry, and the harsh reality of actually providing the ANC function. Part 2 looks at modern ANC systems and how they function, as well as their practical issues. Q: Is ANC using […]
