Abstract
The invention provides an acoustic wave transducer. The transducer comprises a notched shell, a receiving transducer module, a transmitting transducer and a bag, wherein the notched shell is provided with slotted holes for improving the acoustical insulation effect of the notched shell; the receiving transducer module is sleeved in the notched shell and comprises more than two receiving transducers sequentially connected together in series through screw threads; the transmitting transducer of which one end is fixedly connected to the interior of the notched shell is sleeved in the notched shell and arranged on one side of the receiving transducer module; the bag is a flexible part, and is sleeved in the notched shell and wrapped around the receiving transducer module; and oil is filled in the bag. In the transducer, as the receiving transducer module comprises more than two receiving transducers sequentially connected in series through the screw threads, each transducer can be assembled singly and conveniently; the deformation of each transducer is not accumulated during the deformation of the notched shell, so the overall deformation of the receiving transducer module is reduced; in addition, only one end of the transmitting transducer is fixedly connected with the notched shell, so the influence of the deformation of the notched shell on the transmitting transducer can be effectively avoided.
