CUI Devices’ Audio Group today announced the addition of waterproof enclosed speakers to its CES product family. Carrying IP67 ratings, these enclosed speakers feature sound pressure levels (SPLs) from 89 to 106 dB at 10 cm and resonance frequencies from 680 to 1700 Hz. Thanks to their enclosed speaker design and IP67 ratings, the CES series offer engineers […]
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 […]
Integrating absolute encoders – An overview of SPI, RS-485, and SSI protocols
Opportunities for electrically-propelled autonomous mobility and advanced automation continue to multiply in the quest for greater industrial productivity, smarter living, and increased energy efficiency. Encoders can play a large part in these applications as motors require precisely tracked position and motion. However, with multiple encoder types and communication protocols on the market, what are the […]
What are MEMS microphone arrays?
Beamforming arrays let designers create directional microphones using MEMS devices. With the right signal processing algorithms, these can enhance the user experience delivered by many types of audio equipment. An array can be simple, comprising as few as two microphones, and can be arranged in various configurations depending on the expected location of the preferred […]
Choosing the right MEMS microphone interface for your project
Micro-electro-mechanical systems (MEMS) microphones have been steadily increasing their market share, driven by the surge in popularity of voice-controlled electronics with applications like voice-enabled navigation devices and digital home assistants. But what are the different types of MEMS microphone electrical interfaces available and how do you apply them to your application? A MEMS microphone with […]
Choosing the right encoder – open-collector, push-pull or differential output?
Position encoders are widely used in motion control applications and many different types are available. To choose the optimum device for a given application, engineers must decide between absolute, incremental or commutation encoders, which present data in various formats such as quadrature, motor-pole or a serial protocol. The resolution required, as well as dimensions and […]
