1.1.1. Working frequency band
The working frequency band of the transducer is 300Hz~10kHz.
1.2.Resistance and capacitance
Provides resistance and capacitance parameters within the working frequency band of the transducer.
1.3. Emitted sound source level
Measure the sound source level in the working frequency band of the transducer. The sound source level in the 300Hz~1kHz frequency band is not less than 163dB. The sound source level in the 1kHz~2kHz frequency band is not less than 170dB. The sound source level in the 2kHz~10kHz frequency band is not lower than at 180dB.
1.4. Horizontal directivity
Omnidirectional, measuring frequencies 300Hz, 1kHz, 2kHz, 5kHz, 10kHz.
1.5.Vertical directivity
The vertical opening angle in the 300kHz~5kHz frequency band is not less than 85°, and the measurement frequency is 300Hz, 1kHz, 2kHz, 5kHz, and 10kHz.
1.6. Hydrostatic pressure: 0.5MPa.
