使用具有低 SNR、高灵敏度和快速启动时间的 MEMS 麦克风来满足从智能扬声器到耳塞的 VUI 设计要求。
Using specialized MEMS microphones and ultra-low-power microcontrollers, developers can greatly reduce the power needed for always-on voice interfaces.
This video will show Vesper's High AOP Homepod speaker.
VM1010 ZeroPower Listening™ 压电式 MEMS 麦克风
发布日期：2019-03-14
Vesper 的 VM1010 是一款低噪声单端模拟 MEMS 麦克风，具有声音唤醒模式，可提供超低功耗的不间断监听解决方案。
This Application Note will address the selection of design parameters to integrate Vesper’s VM1010 Wake on Sound (WoS) microphone with ZeroPower ListeningTM (ZPLTM) technology into always-on always listening systems.
This Application Note is a reference for the best practices in the manufacturing process using Vesper Piezo MEMS Microphones.
Vesper’s microphones and microphone arrays, and their different uses in the SmartEverything age.
This white paper provides insight into Vesper's ZeroPower Listening™ (ZPL™) technology and emphasizes the importance of ultra-low power technologies to enable battery life savings in an always-listening system.
Vesper's always-on voice-control is already a standard feature in PCs, smartphones and now voice controlled smart speakers which double as home automation hubs.
This white paper will provide insight into microphone selection for far-field performance using the measurement data taken with Vesper’s piezoelectric microphones.
This application note describes how to use Vesper's VM1010 microphone and its Wake on Sound (WoS) mode.
Vesper’s piezoelectric MEMS microphone is fully operational when immersed in water. In fact, it can even work like a hydrophone so it can capture sounds that are otherwise impossible to record.
Vesper’s VM1010 piezoelectric MEMS microphone with ZeroPower Listening, DSP Group’s DBMD6 DSP, and Sensory’s keyword-detection algorithm – increases battery life from 8 hours in always-listening mode.
Vesper’s always-listening piezoelectric MEMS microphones let battery-powered devices stay in wake-on-sound mode without draining the battery.
At Vesper, we built a handler to test thousands of microphones at once. Our microphones arrive in trays, which are fed into our fully-automatic handler. Each microphone is individually tested in a sealed acoustic chamber.
