As a market leader and global provider of advanced micro-acoustic microphones and audio solutions, in these new SiSonic MEMS microphones, Knowles combined low-power, high-performance technologies for high-growth market opportunities.
The new Titan, Falcon and Robin microphones from Knowles were designed to help solve design challenges in size constrained ear/wearable applications, including the thriving category of True Wireless Stereo (TWS) earbuds and all the new related designs for over-the-counter, self-fitting hearing aids and hearables with augmented audio features.
The three new SiSonic MEMS microphones represent an evolution in terms of high signal-to-noise ratio (SNR), and low noise performance, being ideal for Active Noise Cancellation (ANC) applications. Its specifications also allow for a combination of low distortion in loud environments, which is essential in hearables, with high-fidelity sound capture and superior beamforming performance, as required for voice communications and voice commands.
Each of the new SiSonic microphones is helping raise the standards for today’s product designs. The new Knowles Titan (digital) SPH18RILM4H device (pictured above) features a high signal-to-noise ratio (SNR) of 68.5dB with a high acoustic overload point (AOP) at 129dB SPL with 69dB SNR in the 20Hz-10kHz band. The Falcon (analog) SPH11C3LR5H device offers a similar SNR with a higher AOP of 134dB SPL (2.75V), while the smaller Robin (analog) SPV61A0LR5H MEMS microphone device offers 66dB SNR and clean signals up to 130dB SPL with less than 1 percent distortion. The low distortion in loud environments enables high-fidelity sound capture and superior beamforming performance for the smallest of form factors.
A similar level of signal clarity holds true for Falcon (pictured above), and brings even higher signal-to-noise ratio (SNR) performance of 68.5dB further improving TWS applications like Ambient Awareness with less noise. In critical low frequency and speech band use cases, Falcon delivers 69dB. Likewise, Titan offers similar SNR performance to Falcon, while improving battery life by consuming 60 percent lower current (470uA) than typical digital mics and lowering latency to 3us, making it ideal for Active Noise Cancellation (ANC) and always-on applications in digital architectures.
"We are excited to kick off the new year with our latest line-up of SiSonic microphones engineered to improve the everyday audio experiences we desire as consumers. We are seeing global brands adopt our new solutions for the added benefits they enable, including higher performance and better clarity as well as longer battery life in more space-efficient form factors," says Greg Doll, General Manager and Vice President of Product Management for microphones at Knowles.
