CRY6151B Electroacoustic Analyzer

CRY6151B is a robust and reliable electroacoustic analyzer with a frequency range spanning from 20Hz to 20kHz. It is designed to evaluate a diverse array of devices, including USB, Bluetooth®, and noise-canceling headphones; electret, MEMS, and moving-coil microphones; receivers; speakers; Bluetooth loudspeakers; and loudspeaker crossover devices.

Technicians can assess device performance using key metrics and procedures such as sensitivity (SPL), impedance, total harmonic distortion (THD), resonance frequency (F0), headphone balance, headphone positioning, phase, polarity, microphone current and voltage, signal-to-noise ratio (SNR), microphone directivity, speaker Thiele/Small (TS) parameters, and telephone loudness ratings. The CRY6151B offers comprehensive capabilities for thorough and precise evaluation of electroacoustic equipment.

CRY3602 Mouth Simulator with Built-In 20dB Amplifier

CRY3602 mouth simulator is a sound source used to simulate the sound field near the human mouth. It is widely used for testing acoustic parameters such as the frequency response and distortion of telephone transmitters and microphones.

‍CRY3602 mouth simulator has a built-in power amplifier. There is no need to purchase an additional power amplifier. It can be directly connected to a sound card or signal generator, simplifying the connection of the test system.

CRY710 Pneumatic Acoustic Test Chamber

The CRY710 Pneumatic Shielding Box, constructed from welded steel plates, provides robust RF shielding for testing Bluetooth, Wi-Fi, and other devices, effectively preventing interference between production lines. It also offers a soundproof environment for assessing acoustic performance. The pneumatic door can be controlled via the serial port.

‍For quadruplex audio testing of TWS headphones, combining two CRY710 boxes with a CRY6151B enables a single operator to manage two test stations simultaneously, significantly reducing labor costs.
