Description
Technical field
The utility model relates to a kind of commercial anti-theft protection warning device, especially relates to the anti-theft audio magnetic label that a kind of bias slice adopts the employing soft magnetism bias slice that soft magnetic material makes.
Background technology
The sound magnetic technology has been widely used in electronic item and has monitored that anti-theft device reached for two more than ten years, the U.S. Pat 4510489 of putting down in writing original invention discloses some amorphous alloy material strip because of having very high magnetic-elasticity coupling coefficient, so can send the strong resonance signal, and utilize this principle that these materials successfully are applied to commercial burglary-resisting system (sound magnetic system), as the burglary-resisting system of large supermarket.The sound magnetic system mainly comprises detector, demoder, anti-theft audio magnetic target etc.Present anti-theft audio magnetic target can be divided into two kinds: hard target of anti-theft audio magnetic and anti-theft audio magnetic label.The former uses amorphous ribbon as resonance plate, adopts permanent magnetic material (for example permanent-magnet ferrite) as bias slice, and this type of anti-theft audio magnetic target can not be decoded, and can only reuse in the inside, shop; The latter also adopts amorphous ribbon as resonance plate, all adopt half-hard magnetic material be the direct current coercive force then between greater than 10000A/m (125 oersted) less than the magnetic material between the 1000A/m (12.5 oersted) as bias slice, this class anti-theft audio magnetic label (hereinafter to be referred as audio magnetic label) can decode and activate repeatedly, and the method for audio magnetic label by demagnetization decoding on demoder on the commodity of money of having paid allows commodity leave the shop and do not trigger the alarm on doorway.Existing audio magnetic label (referring to U.S. Pat 6359563) as shown in Figure 1, comprise a long and narrow plastic box body and lid lid thereon, lid is formed by stacking by the bias slice and the epiphragma of epiphragma, double faced adhesive tape, half-hard magnetic material from top to bottom successively, the resonance plate of the mutual superposition that above size of placement a slice or a slice and box body are complementary in the cavity of box body, the horizontal archwise of resonance plate, wherein bias slice is the parallelogram or the parallelogram of chamfering.Existing audio magnetic label all adopts half-hard magnetic material to make bias slice, owing to the half-hard magnetic material complex manufacturing, costs an arm and a leg, and is difficult for obtaining, and causes making bias slice cost height with half-hard magnetic material; And because half-hard magnetic material direct current coercive force height (greater than 20 oersteds), direct current remanent magnetism height (＞14kG), the bias slice of half-hard magnetic material will produce stronger " clamping " thereby the resonance amplitude (signal intensity) of effect reduction resonance plate to resonance plate when resonance.Therefore audio magnetic label in the past has to adopt the remedial technique measure of some to reduce this damping action to the resonance amplitude: as bias slice being designed to the complicated parallelogram of chamfering; Resonance plate is made the arc of broad ways bending; The thickness that semihard magnetic bias sheet is placed on resonating cativty outside and increases audio magnetic label is with the distance that increases resonance plate and bias slice or the like (as shown in Figure 2).This not only increases sheet material difficulty of processing and consumptive material, and uneven resonance plate is subjected to slight pressure easily and changes resonant frequency.
The utility model content
The utility model fundamental purpose is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, cost is low, easy to process, save material, the stable anti-theft audio magnetic label of making the employing soft magnetism bias slice of bias slice with soft magnetic material of resonant frequency.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of anti-theft audio magnetic label that adopts the soft magnetism bias slice, comprise long and narrow box body, magnetic bias sheet, the resonance plate that is provided with in the box body, be stamped the lid of forming by double faced adhesive tape and epiphragma on the box body, described epiphragma, magnetic bias sheet and resonance plate are layered arrangement, described magnetic bias sheet is the soft magnetism bias slice, and described resonance plate is straight schistose texture, and described resonance plate is at least a slice.The soft magnetism bias slice adopts soft magnetic material to make, because the soft magnetic material that adopts has the characteristic of low direct current coercive force and low direct current remanent magnetism, make bias slice reduce greatly to " clamping " effect of resonance plate, therefore, bias slice and resonance plate can be made simple straight rectangle, be easy to processing and manufacturing, thickness also can further reduce, and has reduced production cost.
As preferably, described soft magnetism bias slice is arranged on outside the cavity of box body.On the soft magnetism bias slice can be arranged at the bottom of lid or the box.
As preferably, described soft magnetism bias slice is arranged in the cavity of box body, and the soft magnetism bias slice is positioned at the top of resonance plate.Because the soft magnetism bias slice is to the low clamping action of resonance plate, soft magnetism bias slice and resonance plate are placed on together in the resonating cativty of box body and do not influence the warning effect, need not semihard magnetic bias sheet to be placed on the resonating cativty outside to reduce clamping action as in the past all audio magnetic labels, manufacturing process is simplified greatly.
As preferably, described soft magnetism bias slice is arranged in the cavity of box body, and the soft magnetism bias slice is positioned at the below of resonance plate.The soft magnetism bias slice is arranged in the cavity of box body, and the soft magnetism bias slice be positioned at resonance plate above or below do not influence the warning effect.
As preferably, described soft magnetism bias slice is located at the below of lid, is provided with epiphragma between described soft magnetism bias slice and the resonance plate.The utility model also can be provided with epiphragma both are separated as original most audio magnetic label between soft magnetism bias slice and resonance plate, make that the clamping action of soft magnetism bias slice and resonance plate is littler.
As preferably, described soft magnetism bias slice and resonance plate are rectangle.Soft magnetism bias slice and resonance plate also can manufacture other shapes, but soft magnetism bias slice and resonance plate are straight rectangle, make more simple, convenience, greatly reduce production cost.
Therefore, the utlity model has following characteristics: 1. simple in structure, reasonable in design; 2. bias slice adopts soft magnetic material to make, and raw material easily obtains, and cost is low, and the soft magnetism bias slice greatly reduces with most zero " clamping " effect of resonance plate, and bias slice and resonance plate can adopt simple straight rectangular configuration, and be easy to process; 3. can be simply soft magnetism bias slice and resonance plate are placed in the resonating cativty of box body together and do not influence the warning effect, need not to fix their position, manufacturing process be very simple; 4. because manufacturing process is simple, greatly reduce production cost, have vast market prospect.
