Embodiment Construction

[0052] In order to provide an underwater acoustic ultra-wideband combined sound array and launching device that can achieve balanced emission in the entire ultra-wideband range and work in the deep water range, first select a wide-band deep-water deep-water transducer.

[0053] The low-frequency broadband transducer array in the frequency range of hundreds of Hz to several kHz uses rare earth ring transducers. This type of transducer has the characteristics of wide frequency band, small frequency constant, large power capacity and high voltage transmission response. Source level ≥ 175dB, working depth 6000m.

[0054] The intermediate frequency broadband transducer array in the frequency range of a few kHz to more than ten kHz selects the flooded ring transducer, which combines the resonance frequency of the liquid cavity and the radial vibration frequency of the ring, and has a wide frequency range. , The characteristics of large power capacity, its sound source level ≥ 190dB...

Abstract

A method for emitting and combining underwater super wideband sound array includes applying underwater sound synthetic technique and multiarray emission technique of sub frequency channel and multimode vibration ¿C emission transducer to realize free selection of sweep frequency signal combination on sea detecting instruments and any program controlled adjustment of emission operating parameter. An emitting system device of underwater super wideband combined sound array is also disclosed.

Description

[0001] Field [0002] The patent of the present invention relates to the method and device of transducer combination acoustic array and emission system for acoustic wave emission of underwater acoustic detection, especially suitable for combination of underwater acoustic ultra-wideband of ocean detection instruments with different formations, resolutions and formation penetration depths The sound array and launch system device can also be used for underwater communication, telemetry and other marine instruments. Background technique [0003] In the ocean exploration and ocean development activities of the prior art, marine instruments using sound waves as detection means are generally used, and underwater acoustic detection instruments work in the low-frequency band. The acoustic array of the transducer can not only emit high power, but also the emitted acoustic signal has a wide working frequency band. For the existing transmitting transducer, in order to obtain higher elect...
