In the wave of automotive intelligence, Active Noise Cancellation (ANC) and in-car voice communication have become key metrics for assessing cabin experience. For Tier 1 suppliers, how to achieve both high-performance noise cancellation and precise multi-zone voice interaction within the limited interior space is a significant challenge. Kepo’s A2B microphone and speaker series are built precisely for this purpose.
High-Performance ANC: Starting with a Clean Front-End Signal
The effectiveness of an ANC system heavily depends on the quality of the audio signal. Any noise, distortion, or latency directly degrades noise cancellation performance. Kepo A2B microphones, with their core features of high Signal-to-Noise Ratio (SNR) and low Total Harmonic Distortion (THD), deliver clean and accurate reference signals to the ANC controller – whether it’s engine harmonic noise or road and tire noise, all can be captured precisely.
Paired with wideband, high Sound Pressure Level (SPL) speakers, the Kepo solution ensures that anti-noise waves are reproduced in real time and linearly across the target frequency range, forming a solid front-end hardware foundation. From microphone to speaker, the high dynamic range and low distortion across the entire chain allow ANC algorithms to reach their full potential.
In-Car Voice & Cabin Communication: Complete Support from Multi-Zone Arrays
Modern smart cockpits not only need to eliminate noise but also allow every passenger to interact naturally using voice. Kepo A2B microphone arrays enable precise multi-zone voice pickup, distinguishing commands from the driver, co-pilot, and rear-seat passengers through beamforming technology. Together with the cabin communication function, front and rear occupants can talk effortlessly.
The speaker array handles clear voice playback and prompt tones. Kepo’s wideband, high-SPL speakers provide ample dynamic headroom while maintaining low distortion, ensuring that voice interactions remain intelligible even in high-speed driving conditions with wind noise.
Whether it’s pursuing a quiet cabin through active noise cancellation or enabling natural voice communication, the Kepo A2B microphone and speaker series offer a proven, integrated acoustic front-end. We look forward to working with more Tier 1 partners to build quieter and smarter auditory experiences for next-generation intelligent vehicles.
