Chinese Introduction
In the rapidly evolving landscape of audio technology, Micro-Electro-Mechanical Systems (MEMS) microphones have become integral components in various applications, from smartphones to wearable devices. Their compact size and high performance make them ideal for modern electronics. However, as these microphones become more sophisticated, there’s a growing need to enhance their sensitivity while reducing power consumption.
Innovative Design: Integrated Spiral Arm Diaphragm
Recent research has introduced a novel MEMS condenser microphone design that incorporates spiral arms into the diaphragm structure. This innovative approach reduces diaphragm stiffness, thereby enhancing mechanical sensitivity. The design achieves a pull-in voltage of 1.62 V and a mechanical sensitivity of 13.5 nm/Pa, with a resonance frequency of 20 kHz. Fabricated prototypes demonstrated a pull-in voltage of 1.81 V and a sensitivity of 12.23 mV/Pa, marking significant improvements over traditional designs.
Implications for Portable Audio Devices
The reduced pull-in voltage and enhanced sensitivity make this microphone design particularly suitable for low-power, high-performance applications such as smartphones and portable audio devices. The compact dimensions (250 × 250 µm²) align with the miniaturization trends in consumer electronics, offering manufacturers the opportunity to integrate high-quality audio components without compromising on device size or battery life.
