Title:
HYDROPHONE, TRANSDUCTION METHOD, AND COMPOUND HYDROPHONE
Document Type and Number:
WIPO Patent Application WO/2018/041238
Kind Code:
A1
Abstract:
A hydrophone (100, 300) and compound hydrophones (200, 400, 500) made of the hydrophone (100, 300) comprises at least one strip-like transduction element (110, 311), a shell (120) or housing (122), sound-permeable sealing sheet (130, 140) at both ends, and wires (150, 313). The end sound-permeable sealing sheets (130, 140) configured to isolate each strip-like transduction element (110, 311) from the outside, and transmit an acoustic signal in water to it. For compound hydrophones (200, 400, 500), a plurality of strip-like transduction elements (110, 311), each wrapped in shells (120) of soft and high damping material are inserted into the pre-machined cavities (220) in a design hydrophone housing. The plurality of strip-like transduction elements (110, 311) can be electrically connected in parallel, in series or part-parallel and part-series and their axes can be oriented at desired angle to suit various application needs. In the present arrangement, the strip-like transduction elements (110, 311) are free from any constraints and can vibrate freely in half-wavelength mode, giving rise to improved sensitivity and larger working frequency range of the resultant hydrophone.
