Portable loudspeaker CRY604

CRY604 standard sound source is a closed far-field sound source, which can effectively avoid problems such as short circuit and interference compared to conventional open sound sources. CRY604 standard sound source is suitable for acoustic test scenarios that require a single sound source within the long-range (30 cm - 100 cm) free field. The frequency response characteristics comply with the international standard IEEE 269.661 and such characteristics as good low and high frequencies are also available Far-field sound source Closed Good frequency characteristics 1V constant voltage drive (0.25 W), frequency response curve at 10 cm Frequency response curve of 94 dB sound pressure after equalization Total harmonic distortion (THD) curve of 94 dB sound pressure after equalization
