Fuwei Group pushes Wolfson Audio CODECs series products

Fuwei Group pushes Wolfson Audio CODECs series products --- high performance MEMS microphones

Fuwei Group is about to launch Wolfson Audio CODECs products. Based on the development of audio technology, it has created various world-leading products for the entire digital consumer industry. Today, Wolfson is in the next exciting stage of development, which is called "Wolfson AudioPlus â„¢." An innovative strategy. By adding key components including the audio signal chain and accumulating mixed signal technology, this strategy brings a new It is an improved end-user experience and a more highly optimized solution with a higher credit ratio.

"Pursue excellence, challenge the limits"-The Wolfson AudioPlus â„¢ strategy expresses higher expectations, that is, to design more powerful and efficient products that truly enable the differentiation of levels in digital consumer devices.

When the technologies of Wolfson's Pure Sound, Smart Power, Enhanced Soundware, and True Microphone come together, the practice of improving the end user experience will be fully promoted.

Wolfson introduced the world's highest performance, ultra-miniature silicon microphone as the first product in Wolfson's innovative AudioPlus â„¢ True Mics series. The WM7110 and WM7120 provide ultra-high signal-to-noise ratio, low distortion and flat phase response, ensuring a clean pass Transparent audio capture.

The tiny package and ultra-low power consumption make them ideal for portable applications. The selectable minimum sensitivity error is only +/- 1dB, so that the latest microphone array application design can be realized by cost-effective means.

A Brushless DC Electric Motor ( BLDC motor or BL motor), also known as electronically commutated motor (ECM or EC motor) and synchronous DC motors, are synchronous motors powered by direct current (DC) electricity via an inverter or switching power supply which produces an alternating current (AC) electric current to drive each phase of the motor via a closed loop controller. The controller provides pulses of current to the motor windings that control the speed and torque of the motor.
The construction of a Brushless motor system is typically similar to a permanent magnet synchronous motor (PMSM), but can also be a switched reluctance motor, or an induction (asynchronous) motor.
The advantages of a Brushless Motor over brushed motors are high power-to-weight ratio, high speed, electronic control, and low maintenance. Brushless motors find applications in such places as computer peripherals (disk drives, printers), hand-held power tools, and vehicles ranging from model aircraft to automobiles.
