World’s first Piezoelectric MEMS Microphone


Create the most acoustically rich consumer products for all sound environments.

From smartphones and wearables to smart home devices, consumers use sound-enabled products in the real world. That’s why MEMS microphones have to work in real-world environments, not just some of the time, but all of the time. Vesper’s VM1000 does just that.

Robust and Reliable

As the industry’s first piezoelectric MEMS microphone, VM1000 is the most robust and reliable MEMS microphone for consumer products.

It is waterproof, dustproof, particle-resistant and shockproof so you can immerse it in water, bathe it in dust, expose it to particulate matter or drop it on the ground, and it keeps working properly. It’s a microphone on which you can depend. And although your customers won’t recognize it with their bare eyes, they will appreciate it with their ears.

Simplistic design

Consumers want to enable voice control on all their smart home devices

These devices come in various form factors from an ultra compact wearable buttons to TV remotes and Smart speakers. Microphones are at the forefront of these devices and exposed to real-world conditions all the time. Here is where capacitive MEMS microphones fail. Right from the assembly, capacitive MEMS require additional protection to avoid manufacturing failures. They need to have a mesh/membrane to achieve robustness to dust, moisture, kitchen oil etc. making a more complicated design. With an IP57 rating , VM1000 offers robustness to environmental particles along with industry standard acoustic performance , all with no protective elements added to the design.
