An embodiment of the present invention provides a non-reactivatable acoustic-magnetic anti-theft tag, specifically, please refer to fig. 1, fig. 1 shows that the explosion schematic diagram of the non-reactivatable acoustic-magnetic anti-theft tag in one of the embodiments of the present invention, wherein the non-reactivatable acoustic-magnetic anti-theft tag includes: a tag housing 1, at least one resonator plate 2, a magnetic biasing plate 3, and at least two non-magnetized and magnetizable deactivation elements (41 and 42 shown in the figure);

the embodiment of the utility model provides an in, label shell 1 is encapsulated situation in the course of the work, and it has the cavity, and the quantity and the size of cavity are decided by actual label type and designing requirement (the quantity of cavity in this embodiment is 1), no longer give unnecessary details here, and each resonance piece 2 is located in the cavity, on the same principle, when there are a plurality of cavities, each resonance piece is decided by actual label type and designing requirement in the distribution state in the cavity.

For the magnetic bias plate 3, which is magnetized to generate a normal operating field strength (e.g. about 4 to 7 Oe) so that the resonant frequency (e.g. 57.5kHz to 58.5 kHz) of the acoustic-magnetic anti-theft tag can be detected by the detector, preferably, the magnetic bias plate 3 is disposed in the cavity or on the outer side of the tag shell 1 and is arranged in a layer with the resonance plate 2, thereby ensuring the resonance effect of the resonance plate 2.

When the magnetic bias piece 3 in the present tag is demagnetized (demagnetized), the resonant frequency of the acoustic-magnetic anti-theft tag rises (for example, rises to a detection window greater than 59.5kHz and greater than 57.5kHz to 58.5 kHz), so that the detector cannot detect the deactivated acoustic-magnetic anti-theft tag, but in the prior art, when the acoustic-magnetic anti-theft tag is close to a natural or unnatural magnet (for example, close to a magnet with a surface field greater than 500 Oe), the acoustic-magnetic anti-theft tag returns to the resonant frequency which can be detected by the detector when activated, and then is detected by the detector. The embodiment of the utility model provides an acoustic magnetic anti-theft label be equipped with not magnetized prevent the activation piece locate in the cavity or on the outside of label shell 1, the biasing piece just can not trigger the warning by the demagnetization after being used, even after carelessly be close to a surface field and be greater than 500 Oe's magnet behind, prevent the activation piece by magnetizing, superpose the magnetic field of magnetized biasing piece, far exceeded the required magnetic field intensity 4 ~ 7Oe of normal operating point, can be detected by the detector when this label can not get back to the activation resonant frequency, preferably, acoustic magnetic anti-theft label's resonant frequency at this moment is 57.0kHz minimum, is less than 57.5kHz ~ 58.5 kHz's detection window, so also can not detected by the detector, can't be activated once more.

Further, in the above embodiment, the width of the resonator plate 2 is 1.6mm to 5.3mm. The width of the resonance piece of the existing acoustic-magnetic anti-theft tag is generally 6mm, and 1 piece (such as LE or AP of American Signal transducer, NST1T of Ningbo Signal Strong electronics Co., ltd.), 2 pieces (such as DR or APX of American Signal transducer, ltd.), and 3 pieces (such as NST3T of Ningbo Signal Strong electronics Co., ltd.) are provided. However, the inventors have found that the alarm distance of a plurality of plates decreases more slowly when the resonance plate is narrowed than when the resonance plate is single-plate. For example, when the widths of the resonance plates are substantially the same, the widths of the resonance plates are reduced, and the alarm distance of the anti-theft tag is about 95% of the original average alarm distance. The alarm distance of the single-chip resonance piece is reduced by more than 40% due to the same width change, and the difference is probably caused by the fact that the effective width is slightly larger than the width of the single-chip when a plurality of resonance pieces are not arranged in a uniform way, and the interaction of the resonance pieces is more complicated than the resonance characteristic of the single-chip. The non-crystalline price of comprehensive consideration (amorphous indicates that the resonance piece is amorphous alloy that FeNiMoB is the base promptly, or amorphous alloy that FeNiCoSiB is the base), factors such as raw and other materials such as off-set piece and double faced adhesive tape, the embodiment of the utility model provides a through the width design with the resonance piece for 1.6mm ~ 5.3mm, narrowed the acousto-magnetic label width, can be used to protect the product of narrow type or needs exquisite appearance, for example based on 3-5 resonance pieces (like the narrow mark NTL of Ningbo news forceful electronics branch of academic or vocational study limited company) plus prevent reactivation piece constitution.

Of course, in this embodiment, except for the rectangle, the shapes of the box body and the box cover need to be combined with specific models and product design requirements, and are not described herein again.

Further, in the above embodiment, at least one position of the outer part of the box body has a width of 3.5mm to 6.5mm, and the width of the corresponding box cover is 4.0mm to 7.9mm.
