Embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.Be understandable that specific embodiment described herein only is used for explaining the present invention, but not limitation of the invention.
Fig. 1 is the structural representation of facing of a kind of piezoelectric ceramic loudspeaker of providing of the embodiment of the invention and close range wireless communication antenna integrating device, and as shown in Figure 1: described piezoelectric ceramic loudspeaker and close range wireless communication antenna integrating device comprise:
Piezoelectric ceramic loudspeaker 101; The oscillating plate 102 of bonding piezoelectric ceramic loudspeaker; Close range wireless communication antenna 103; Wherein, the close range wireless communication antenna is centered around around the piezoelectric ceramic loudspeaker, is adhered on the oscillating plate 102.
Wherein, for in the volume that reduces oscillating plate 102, do not influence vibrating effect and the firm degree of oscillating plate 102, selecting the scope of oscillating plate 102 thickness is 0.1mm-20mm, can in this thickness range, select the thickness of oscillating plate 102 according to concrete needs, for example, need the volume of oscillating plate 102 smaller, just select thinner thickness, need oscillating plate 102 firmer, just select thicker thickness, the thickness that embodiments of the invention preferably adopt has several sizes such as 1mm, 3mm, 5mm, 10mm, 15mm.
Wherein, being shaped as of oscillating plate 102 and piezoelectric ceramic loudspeaker 101 is square, rectangle, circle, annular, polygons or butterfly shape etc., can adopt rectangular array to arrange or other shapes are arranged, the shape of oscillating plate 102 and piezoelectric ceramic loudspeaker 101 and big I determine according to concrete needs, and mainly housing 104 inner surface configurations and the size by the equipment of bonding oscillating plate 102 decides.
Fig. 2 is a kind of piezoelectric ceramic loudspeaker of providing of the embodiment of the invention and the side-looking structural representation of close range wireless communication antenna integrating device, as shown in Figure 2: piezoelectric ceramic loudspeaker 101 can use one or two, if use a piezoelectric ceramic loudspeaker, then Pasting is in the center of any side of oscillating plate 102 or near the position at center, the position of piezoelectric ceramic loudspeaker 101-1 or piezoelectric ceramic loudspeaker 101-2 for example, if use two piezoelectric ceramic loudspeakers, then can be pasted on center or the position at close center, for example position of piezoelectric ceramic loudspeaker 101-1 and piezoelectric ceramic loudspeaker 101-2 of the both sides of oscillating plate 102 simultaneously.
Wherein, spray printing has the Ferrite Material of antijamming capability on piezoelectric ceramic loudspeaker 101 outer surfaces, the outer surface of the piezoelectric ceramic loudspeaker 101 contacted surface of oscillating plate that refers to get along well.Ferrite Material, principal component contains iron oxide, cupric oxide, zinc oxide and the nickel oxide of ormal weight, auxiliary element contains bismuth oxide, silica, magnesium oxide, the cobalt oxide of ormal weight, nickel, copper, Zn ferrite material temperature characteristic fabulous (rate of change with respect to the magnetic permeability of variations in temperature is little), quality factor height, intensity height.With regard to electrical characteristics, ferritic resistivity is more much bigger than metal, alloy magnetic material, and also has higher dielectric property.Ferritic magnetic property has higher magnetic permeability when also showing high frequency.Thereby ferrite becomes the broad-spectrum nonmetal magnetic material in high frequency light current field.The main effect of Ferrite Material is to reduce metal material to the absorption in signal magnetic field, and ferrite membrane itself is a kind of Ferrite Material of high temperature sintering simultaneously, by increasing magnetic field intensity, effectively increases distance of reaction.
