Due to size restrictions, traditional state-of-the-art small directional microphones suffer from a greater noise level. a tiny directional microphone that mimics the ear architecture is the main goal of getting a greater signal-to-noise ratio at a smaller size.
The microphone is shaped like a circle and includes a piezoelectric readout system made of aluminum nitride (AlN) placed in the middle of the diaphragm.
The 3-3 transduction mode is used to increase sensitivity. An anechoic chamber is used for the microphone testing. Aside from the bidirectional response, the optical directional microphone of Miles et al.,
which is the most well-known noise analysis work in the field of bio-inspired MEMS directional microphone, has an A-weighted noise under broadband excitation of 29 dBA, which is lower than the optical directional microphone.
The Global bio-inspired directional MEMS microphone market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The first bio-inspired directional microelectromechanical systems (MEMS) microphone, by Soundskrit, has been unveiled. It is intended to offer high-quality audio to existing and future connected consumer gadgets.
The SKR0400 is a MEMS microphone that combines proprietary software for a variety of devices and use cases with a novel transducer design for optimal audio performance.
These consist of: Laptops, Wireless speakers, Digital TVs, Earbuds and headsets, Virtual or augmented reality, engineering in healthcare, Wearables, connected automobiles.
With a highly directional pickup pattern that removes background noise and reverberation from audio and isolates a user’s voice with high-fidelity, the MEMS microphone reduces unwanted noise at the hardware level.
The sensor replaces the requirement for bulky omnidirectional microphone arrays with compact, lightweight, low-power alternatives for better performance. very little signal processing
