Acoustic wave transducer

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.

Description

Technical field [0001] The invention relates to an acoustic wave transducer. Background technique [0002] The structure of the traditional acoustic transducer is as figure 1 As shown, a slotted housing 1, a receiving transducer 5, a transmitting transducer 6 and a bladder 4 are included. The receiving transducer 5 and the transmitting transducer 6 are sleeved and fixed in the slotted housing 1 in parallel, and the bladder 4 is used to wrap the receiving transducer 5. [0003] The receiving transducer in the traditional acoustic wave transducer 5 such as figure 2 As shown, the receiving transducer 5 is formed integrally and rigidly connected by an internal mounting rod 51. When the grooved housing 1 of the acoustic wave transducer is deformed, the receiving transducer 5 is easily deformed, thereby affecting the performance of the receiving transducer 5.

AI Technical Summary

Problems solved by technology

When the slotted shell 1 of the acoustic wave transducer is deformed, it is easy to cause the receiving transducer 5 to deform, thereby affecting the performance of the receiving transducer 5

In addition, this structure is very unfavorable to the wiring and assembly of the receiving transducer 5, and it is very troublesome in the actual operation process.

[0004] The transmitting transducer 6 in the traditional acoustic wave transducer is as figure 1 , image 3 As shown, the two ends of the transmitting transducer 6 are fixed in the slotted shell 1 by threads, which are easily affected by the deformation of the slotted shell 1, thereby affecting the performance of the transmitting transducer 6

Especially when carrying the acoustic wave transducer, since the acoustic wave transducer is slender, it will be bent, and the transmission to the emitting transducer 6 will cause the emitting crystal 7 to break

In addition, the emitting crystal 7 of the emitting transducer 6 is elastically fixed only by the apron 8. Since the elastic deformation of the apron 8 is relatively small, when the emitting crystal 7 has a large deformation, the problem of fragmentation of the emitting crystal is very likely to occur. cause unnecessary loss
