Abstract:
     Hydrophone is composed of quadrate external case, dual pieces of lamination inside case, cylindrical base for placing quadrate external cases in wing profile type. Using mould, the technique prepares the quadrate external case from admixture of epoxy resin in low density and micro glass bead. Comparing with vectorial hydrophone in low frequency in other structure, the disclosed hydrophone possesses advantages of small size, lightweight, good directivity, sensitivity of channels and phase characteristics so as to solve issue of designing sonar array. The invention can widely applicable to each area of hydroacoustics such as sonobuoy, navigation for torpedo, submarine communication system to execute high-frequency measurement task.
