In the SensiBel MEMS Microphone
The SensiBel MEMS Microphone is a breakthrough in miniature audio technology. It achieves studio-quality audiousing an innovative optical sensing method based on laser interferometry, rather than the traditional capacitive or piezoelectric principles. This design allows for extremely flat frequency response, ultra-low noise, and impressive high-SPL handling—all within a MEMS-sized package.
Key Features of the SensiBel MEMS Microphone:
- Optical Sensing: Uses a VCSEL (Vertical Cavity Surface Emitting Laser) and photodetector to sense diaphragm movement.
- High Signal-to-Noise Ratio (SNR): Up to 80 dB, enabling clean audio capture in both quiet and loud environments.
- Studio-Grade Frequency Response: Flat response starting as low as 10 Hz.
- High Acoustic Overload Point: Around 130 dB SPL, ideal for high-pressure sound environments.
- Low Power Operation: 1.8 V supply, suitable for battery-powered devices.
Output Interfaces:
- Digital Interfaces: Supports PDM, I²S, and TDM.
- No need for external ADCs or analog front ends, simplifying system integration.
Evaluation Kit – Aurora:
To evaluate the SensiBel MEMS Microphone, engineers can use the Aurora Evaluation Kit:
- Rapid setup with PDM or I²S mic options.
- USB connectivity for instant testing.
- Plug-and-play with included software.
- Studio-quality audio monitoring in minutes.
Applications:
- Smart speakers and wearables
- Hearing aids and audio recorders
- Medical devices and assistive tech
- Consumer headsets and AR/VR gear
Despite its compact size—no larger than a fingernail—the SensiBel MEMS Microphone rivals large-diaphragm studio mics in audio fidelity. If you’re designing an embedded system where sound quality can’t be compromised, this optical MEMS microphone is a truly disruptive choice.
With the SensiBel MEMS Microphone, engineers can now deliver high-fidelity audio in form factors previously limited to low-grade performance, all while benefiting from simplified digital integration and unmatched sound clarity.
