21ic News Vesper announces the introduction of the piezoelectric microelectromechanical system (MEMS) microphone VM101 with a typical signal-to-noise ratio (SNR) of 68 dB, which is the highest acoustic performance benchmark for commercial MEMS microphones.
The VM101 is the first MEMS microphone with ultra-high SNR, which solves many of the major performance challenges faced by consumer electronics manufacturers and improves the quality and clarity of audio capture, dramatically improving smartphones, wearables, and smart home appliances. And the voice user interface of the Internet of Things (IoT) device.
Vesper CEO Matt Crowley said: "It is expected that voice will replace touch as the main user interface for consumer electronics. As the microphone happens to be at the starting point of the audio signal chain, better performance MEMS microphones become especially critical."
In addition to providing superior acoustic performance, the VM101 is the only MEMS microphone that is waterproof, shock-resistant, dust- and particle-resistant, and is extremely attractive to manufacturers with extremely high reliability requirements.
Crowley said: "In fact, even if the VM101 is thrown into the sea or buried on the beach, it will still work. In the repair of the smartphone, the microphone failure is the second most common cause after the screen is broken. It is important to see the reliability of the microphone. Using this highly reliable microphone product can reduce the many reliability problems that cause headaches for manufacturers, thus reducing the product repair rate."
Robust and ready
The VM101 has an SNR of 68 dB and is almost twice the performance of today's high-end 65 dB SNR capacitive MEMS microphones. Vesper's new MEMS microphone's superior far-field audio performance doubles its sound capture distance, and its ambient noise cancellation capability greatly improves the clarity of the phone call, enriching the user's voice-enabled application experience. This is extremely important for improving the acoustic performance of voice commands and smartphone controls, "audio amplification" recording, voice-enabled smart home devices and smart TV remote controllers. For example, a smart TV remote will allow consumers to accurately navigate through menus, access websites, and record shows by replacing touch with sound.
Microphone array
MEMS microphones are typically used in microphone arrays containing up to four microphones, which makes the stability of the microphone critical. Unlike a capacitive MEMS microphone that is prone to performance drift once it leaves the factory, the VM101 is very stable, making it ideal for microphone array applications such as:
· Far-field audio – improves sound capture even at longer distances
· Environmental noise cancellation – improving clarity and visibility of phone recordings or calls
· “Audio Enlargement†– focus on a single sound source during recording to make sound selection more accurate
