Abstract:
     The hydrophone is composed of disk shaped external case with wire guide, silicon micro acceleration sensor inside case, and suspension gear. Using mould, the technique prepares the disk shaped case from admixture of epoxy resin in low density and micro glass bead. Comparing with vectorial hydrophone 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 low-frequency measurement task.
