Hangzhou Crysound Electronics Co., Ltd. products

CRY2623 is a hand-held industrial acoustics imager that supports ultrasonic frequency band.The instrument uses the microphone array beamforming technology to acquire the sound source distribution data, and collects the video images in real time with the high-definition camera. By integrating the sound source distribution data with the video image, the changing sound source is dynamically presented on the display screen.

CRY6151B is a full-featured electroacoustic tester newly launched by CRY Sound. It is powerful and stable. It can measure the performance indicators of headphones (USB, Bluetooth, anti-noise), microphones (electret, MEMS, moving-coil type), headphone and microphone assemblies, receivers/headphone speakers, speakers/loudspeakers (common, Bluetooth), loudspeaker crossover devices, and other electroacoustic devices, such as sensitivity (SPL), impedance, distortion (THD), resonance frequency F0, left and right headphone balance, left and right headphone position, phase polarity, microphone current and voltage, SNR, microphone directivity, speaker`s TS parameters, telephone receiving and sending loudness ratings, etc. Its test frequency range can be up to 20 Hz - 20 kHz.

CRY2851 Sound Level Meter is designed for noise measurement, environmental and industrial product measurement. With high-performance processor, CRY2851 has ability to do frequency analysis, data logging, wireless control and transmission accurately and reliably. CRY2851 Sound Level Meter follows GB/T3785.1-2010 Class 1, IEC61672-1: 2013 Class 1 Standard.

Frequency response: 3.15 Hz - 16kHz; sensitivity: 40 mV/Pa. CRY331-CRY507 1/2" IEPE Free-Field Measurement Microphone Kit This kit consists of CRY331 Measurement Microphone and CRY507 IEPE Preamplifier self-developed by CRYSOUND, with a BNC port for output. CRY331 Measurement Microphone can also be combined with CRY510 to launch a kit.

CRY5520 Audio signal generator uses SCM for sweep control and the digital-analog mode and performs stably. With very low distortion, sine wave output, good stability, and frequency range for the entire audio frequency domain, it is especially suitable for the pure tone test of speakers and headphones. It can work in both logarithmic sweep and manual frequency modulation modes. The sweep start point, end point and sweep time can be set randomly. Manual frequency modulation is divided into rough modulation and fine modulation, which can quickly and accurately modulate frequency. It adopts 128 × 64 dot matrix LCD and simultaneously displays frequency and voltage values with synchronous output.
