Embodiment
To develop simultaneously embodiment below in conjunction with accompanying drawing, describe the present invention.
As shown in Figure 1, the invention provides and be a kind ofly applied to anti-acoustic receiver of hunting the large reception directive property angle of release of submarine mine, this acoustic receiver comprises high frequency piezoelectric ceramic spherical shell 1, watertight sound transmitting rubber 2, matrix 3, rubber sheet gasket 7 and connector 9;
Described high frequency piezoelectric ceramic spherical shell 1 is processed with cable-through hole 5;
Described matrix 3 is processed with a cylinder shape groove, the bottom surface of this groove is processed with matrix cable-through hole 8;
As shown in Figure 2, described rubber sheet gasket 7 is processed with centre bore, the surface of rubber sheet gasket is also processed with a rectangular recess, rectangular recess connects with centre bore in the longitudinal direction, the negative wire welded with negative pole phase of solder joint is held in the effect of rectangular recess, makes acoustic receiver guarantee the reliability that solder joint welds when being subject to vibrating;
Radius be high frequency piezoelectric ceramic spherical shell 1 inwall of 19mm near high frequency piezoelectric ceramic spherical shell cable-through hole 8, one end of welding positive wire, form positive pole solder joint 4, the positive wire welded one end, is drawn by high frequency piezoelectric ceramic spherical shell cable-through hole 5; At high frequency piezoelectric ceramic spherical shell 1 outer wall near high frequency piezoelectric ceramic spherical shell cable-through hole 5 position, one end of welding negative wire, forms negative pole solder joint 6; Piezoelectric ceramic ball shell 1 and rubber sheet gasket 7 are bonded together, the positive wire of high frequency piezoelectric ceramic spherical shell 1 and negative wire is drawn by the cable-through hole on rubber sheet gasket 7 simultaneously; Rubber sheet gasket 7 is bonded in the bottom centre position of matrix 3 inner chamber, the positive wire of high frequency piezoelectric ceramic spherical shell 1 and negative wire is drawn by matrix cable-through hole 8 simultaneously, and be connected with the connector 9 on matrix 3; Connector 9 is fixed on matrix 3 cable-through hole 8 exit, and high frequency piezoelectric ceramic spherical shell 1 outer wall perfusion watertight sound transmitting rubber 2, watertight sound transmitting rubber 2 covers whole high frequency piezoelectric ceramic spherical shell 1.
Operation principle: the centre of sphere of definition high frequency piezoelectric ceramic spherical shell 1 is the origin of coordinates, and the vertical direction that high frequency piezoelectric ceramic spherical shell 1 receives the episphere spherical crown of sound wave is z-axis direction, and the centre of sphere and matrix 3 upper surface of high frequency piezoelectric ceramic spherical shell 1 are in same level; Defining this face is x-o-y plane, and x-axis and y-axis are mutually vertical; Due to high frequency piezoelectric ceramic spherical shell 1 reception directive property along oz axle be axial symmetry distribution, so along oz axle formed any plane in reception directive property be all consistent.In practical application, generally select along the reception directive property in any plane of oz axle formation to reflect the directive property of acoustic receiver.By the directive property result of the two-dimentional directivity pattern reflection acoustic receiver of acoustic receiver in y-o-z plane in this example; As shown in Figure 3, the angle that the line of objective definition and initial point and oz axle are formed is incidence angle θ.Definition incidence angle θ y-o-z plane first quartile be on the occasion of, be negative value at y-o-z plane second quadrant.Therefore with high frequency piezoelectric ceramic spherical shell 1 centre of sphere for initial point, target at the poincare half plane of y-o-z plane with the constant distance of distance initial point, when changing incidence angle θ from-90 ° ~+90 ° motions, acoustic receiver must obtain one group and change and the data of change with incidence angle.Data are normalized, the directivity pattern of acoustic receiver will be obtained; As shown in accompanying drawing 4,5,6,7, figure China and foreign countries circular scale is 25dB, and interior circular scale decrement step size is 5dB.
