The main control board usually supports multiple working modes such as WIFI and Bluetooth, and parses MIC voice commands; The power amplifier board realizes voice playback of Smart speaker; The MIC board realizes voice command recording, usually recording 6-8 microphones simultaneously; Other auxiliary function boards such as buttons, LEDs, etc.
This system adopts our own high-performance dual-channel audio analyzer A4, which cooperates with the acoustic automatic test software and related test accessories and sound insulation boxes developed by our company to realize automatic testing of various audio and electro-acoustic indicators.
The electroacoustic testing software option provides a comprehensive solution for ABTEC audio analyzers, allowing designers and production engineers to test electroacoustic products end-to-end. Measurement data, results, reports, and automation can be easily shared, allowing designers and production engineers to collaborate with each other even if they are far apart, ensuring quality.
Perceived audio measurement is widely used in smartphones, VoIP networks, and device testing to measure how people perceive sound quality. Perceived sound quality testing is particularly useful for devices with limited bandwidth or bit rates. Using standard sine wave testing parameters such as frequency response/distortion cannot effectively test and compare the performance of different devices. Only a combination of perceptual and electrical audio testing can fully demonstrate the performance of these devices.
