CRY6151 electroacoustic analysis system is a fully functional electroacoustic device tester launched by our company, with a history of 10 years. It is powerful, highly stable, and capable of measuring the performance indicators of various electroacoustic devices such as headphones (USB, Bluetooth, Regular), microphones (Electret, MEMS, Dynamic), headset microphone combinations, receivers/headphone speakers, speakers/sound boxes (regular, Bluetooth), communication headsets, crossover devices, and other electroacoustic components. These indicators include sensitivity (SPL), impedance, total harmonic distortion (THD), resonance frequency (F0), left-right headphone balance, left-right headphone positioning, phase, polarity, microphone current and voltage, signal-to-noise ratio, microphone directivity, speaker TS parameters, telephone receiver loudness, transmission loudness, and more. The test frequency range can reach 20Hz to 20kHz.
