New external microphone available from Avnet Abacus reduces noise for enhanced in-car voice communication

AA037-Kingstate_microphoneAvnet Abacus, one of Europe’s leading interconnect, passive, electro-mechanical and power distributors and a business unit of Avnet Electronics Marketing EMEA, a business region of Avnet, Inc., has announced availability of a new high-performance external car microphone developed by Kingstate, a leading manufacturer of electro-acoustic components.

This new unidirectional microphone is optimised to deliver the very highest quality acoustics and noise reduction capability essential for the safe use of in-car multimedia, communications and satellite navigation systems. It features high (-37dBV) supercardioid sensitivity to enhance the definition of reception at the front of the vehicle while reducing sound pick-up from the side and rear, and a high signal-to-noise ratio (SNR) of 69dBA, to provide optimal communication performance for speech recognition, voice speed dial and GPS navigation.

With overall dimensions of just 11.7mm (diameter) x 25.5mm, the compact microphone is encased in lightweight and durable aluminium alloy. High frequency noise is effectively filtered out, thanks to the deployment of a high-performance junction gate field-effect transistor (JFET) at the core of the electret condenser microphone (ECM), plus a low pass filter (LPF) output circuit that detects and passes low frequency signals.

Kingstate has more than 30 years’ experience in the development of advanced electro-acoustic products, including piezo buzzers, magnetic buzzers, micro speakers, dynamic receivers, electret condenser microphones and earphones.  These products, including the new external car microphone, are fully supported across Europe by the applications and sales teams of Avnet Abacus.
