Acoustic receiving module of horizontal control device

The invention provides an acoustic receiving module of a horizontal control device. The acoustic receiving module comprises an acoustic signal receiving unit and an acoustic transducer, wherein the acoustic signal receiving unit comprises a digital signal processor (DSP) receiving circuit and a communication control circuit, the DSP receiving circuit is connected with the acoustic transducer, the communication control circuit is connected with a communication coil of the horizontal control device and interacts with the DSP receiving circuit, the acoustic transducer comprises a piezoelectric ceramic spherical shell and a circuit lead-out end, the inner surface and the outer surface of the piezoelectric ceramic spherical shell are coated with electrodes which are polarized in the thickness direction, and the circuit lead-out end is used for outputting acoustic signals produced by the piezoelectric ceramic spherical shell. The acoustic receiving module is applied to the horizontal control device used for collecting towing cable arrays and is simple in structure, reliable in operation and suitable for ocean operating environment.
