Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] like figure 1 Shown is a schematic diagram of an exploded structure of an adjustable thin-plate combined flextensional transducer. The present invention includes a flextensional housing, a drive assembly, a left transition block 6, a right transition block 4, and a flextensional housing for adjusting the flextensional housing. Body adjustment device;

[0030] join figure 1 and figure 2 , wherein the flexural shell is a split structure, including an upper thin plate 17 and a lower thin plate 14; the upper thin plate 17 and the lower thin plate 14 are arc-shaped plates formed by bending and forming a wooden mold; the upper thin plate 17 and the lower thin plate 14 are respectively It is fixedly installed on the left transition block 6 and the right transition block 4 through set bolts 15 and forms a space for installing the drive assembly. Such a design is ...

Abstract

The invention provides an adjustable thin plate combination type flex-tensional transducer. The adjustable thin plate combination type flex-tensional transducer comprises a flex-tensional housing, a driving component, a left transition block, and a right transition block. The driving component is disposed in the flex-tensional housing. The left transition block and the right transition block are used to connect the two ends of the driving component with the inner end surfaces of the two sides of the long axis of the flex-tensional housing. The adjustable thin plate combination type flex-tensional transducer is characterized in that the flex-tensional housing adopts a split structure, and comprises an upper thin plate and a lower thin plate; the upper thin plate and the lower thin plate are arc-shaped plates formed by bending sheet materials via a wooden form; the upper thin plate and the lower thin plate are fixedly disposed on the left transition block and the right transition block by fastening blots to form elliptical space used for the installation of the driving component. The adjustable thin plate combination type flex-tensional transducer is used to solve problems of conventional large-scale flex-tensional transducers such as hard forming of produced housing, high processing technology requirement, and nonadjustable prestress after the forming of the housing.

Description

technical field [0001] The invention relates to an acoustic transducer, in particular to an adjustable thin-plate combined bending-tension transducer. Background technique [0002] Flextensional transducers, especially Type IV flextensional transducers, are very common transducers, especially in the field of underwater acoustics, where they are more widely used, and there are many improved structures based on this type of transducer, such as the fish lip type Flextension transducer. The radiation frequency of the transducer is closely related to the size of the transducer, especially the size of the shell. However, when the frequency of the transducer is reduced or the radiation performance is increased, the scale of the transducer shell will increase significantly, and the displacement and deformation of the shell will also increase. [0003] At present, the traditional bending and tension shell forming mostly uses high-quality alloy materials for forging, stress relief, w...
