Knowles introduces new line of automotive-grade MEMS microphones
Knowles, a supplier of micro-acoustic microphones, speakers, audio processing, and precision device solutions, is making available two new SiSonic MEMS microphones for automotive applications.
The new microphones – SPH1878 and SPH9855 – have been engineered to meet the increasing demands of the automotive market for hands free calling, advanced voice assistance and in-cabin noise cancellation for passenger comfort.
These microphones follow the AEC-Q100/103 qualification requirements set by the Automotive Electronics Council, the standardisation body for establishing standards for reliable, high quality electronic components for use in the harsh automotive environment.
“We are pleased to introduce a new grade of MEMS microphones for the automotive industry and look forward to providing manufacturers with additional capabilities to develop better voice call quality and innovative audio features, as well as enable quieter travel for years to come,” said Greg Doll, General Manager and Vice President of Product Management at Knowles.
The SPH1878 features both a single-ended and differential analogue interface, while the SPH9855 features a PDM digital interface. The two microphones are designed for beam forming applications and are compatible with the European eCall communication system.
Key features include low phase distortion for superior noise cancelling performance, high dynamic range for enhanced call and sound quality, an extended operating temperature range for automotive applications, and improved manufacturing stability and traceability.
