VM1001 is the most robust and reliable MEMS microphone for consumer products with microphone arrays.
It is natively immune to environmental contaminants such as water, dust, moisture, kitchen oil etc. This means the microphone arrays will always stay in sync to ensure consistent beamforming performance. Whether its a Smart speaker used in kitchen or an outdoor security camera, VM1001 is a microphone you can count on for accurate speech recognition performance using microphone arrays.

VM1001 is an omnidirectional, single-ended analog output MEMS microphone.
Consumers want to control their devices from across the room using voice
They want to have far-field voice control enabled on their smart home and IoT devices. It is far-field audio applications like these that are making microphone arrays so popular, but there’s a problem: Microphone arrays require microphones that are carefully matched in terms of phase and sensitivity. From wall powered smart speakers and appliances to smart earbuds used in the outdoor , microphone arrays always need to provide accurate speech recognition in harsh environmental conditions.
Here again, capacitive MEMS microphones fail. Once they leave the factory floor, they are prone to “drift,” so their performance is unstable. Even with a calibrated system, their vulnerability to clog up with dust, dirt and moisture would make that calibration invalid after some time. With a robust piezoelectric MEMS construction and a much simpler manufacturing process , VM1001 ensures that phase and sensitivity are well matched even in harsh environments to meet the needs of voice enabled products.
