Piezoelectric MEMS microphones provide a fresh low-power option without sacrificing mechanical integrity, allowing device manufacturers to incorporate larger mic arrays into products used in adverse conditions both inside and outside the home.
A type of microphone that detects acoustic vibrations by coming into touch with solid objects is a contact microphone, commonly referred to as a piezo microphone. Contrary to typical air microphones, contact microphones only transmit sound that is carried by structures and are virtually insensitive to air vibrations.
Piezoelectric MEMS microphones provide a fresh low-power option without sacrificing mechanical integrity, allowing device manufacturers to incorporate larger mic arrays into products used in adverse conditions both inside and outside the home. The first piezoelectric MEMS microphone to be sold commercially was created by Vesper Technologies. Its primary distinction is that it doesn’t require
The Global Piezoelectric MEMS Microphone market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The VM3000, the newest piezoelectric MEMS microphone in Vesper’s product line, was unveiled today by the company that created the most cutting-edge acoustic sensors in the world. The VM3000, the company’s first digital microphone, significantly increases the range of applications that may be handled by sturdy piezoelectric MEMS microphones.
With a starting time of less than 200 microseconds, this high-performance, low-power microphone provides exceptional performance in all settings.
Smartphones, cars, laptops, and smart speakers are examples of applications that could benefit from a digital interface.
Pulse density modulation (PDM) output, which enables multiplexing of two microphones on a single data line, is a feature of the VM3000. It also has a high immunity to electromagnetic interference (EMI) and radio-frequency interference (RFI), giving designers more freedom in how the microphones are configured.
“Vesper’s piezoelectric MEMS will be able to be employed in a very wide range of applications and be paired with just about any audio chip thanks to the VM3000, first digital microphone. Massive arrays, physically large systems, and circumstances with a lot of RF interference will benefit most from it.
This demonstrates Vesper’s ability to create intricate, high-performing application-specific integrated circuits (ASICs) that work well with our game-changing MEMS technology.
