The hard pieces 3 can also be in a wave structure, so that the hard pieces 3 have better bending resistance. Of course, the hard members 3 may also be a grid structure, a cylindrical structure, a square column structure, or the like, and are not limited in particular.

In summary, after intensive research and a great deal of creative work, the inventor of the present invention finds that, when the dimension of the length, width and thickness of the hard member 3 satisfies the above formula and numerical range, the hard member 3 has good bending resistance, and can effectively prevent the acoustic-magnetic anti-theft tag in the acoustic-magnetic anti-theft tag bag from being easily deformed, bent and scrapped when being bent by an external force, so as to effectively prevent a thief from bending the tag to destroy the tag alarm performance.
In the above embodiment, further, a glue layer (not shown) is disposed on one side of the hard member 3; the hard piece 3 is adhered to the inner side of the bag body 1 through the adhesive layer, or the hard piece 3 is adhered to the outer side of the box body 20 through the adhesive layer.
In this embodiment, through be equipped with on a side of stereoplasm piece 3 the glue film is convenient for like this let stereoplasm piece 3 along the length direction of box body 20 firmly glues to be located on the box body 20, perhaps along the length direction of bag body 1 firmly glues to be located the predetermined place of bag body 1, thereby makes stereoplasm piece 3 is in bag body 1 is not fixed and the phenomenon that misplaces probably appears and leads to can not playing good bending-resistant effect to the acoustomagnetic antitheft label.
As another example, the hard members 3 may be directly provided inside the case 20 along the length direction of the case 20.
In the above embodiment, the ratio of the length of the hard members 3 to the length of the case 20 is, for example, 0.5 to 1.2.
After research and a great deal of creative work, the inventor finds that when the ratio of the length of the hard piece 3 to the length of the box body 20 is 0.5-1.2, the hard piece 3 can effectively resist bending of the acoustic-magnetic anti-theft tag. If the length of the hard member 3 is too short relative to the length of the box 20, the hard member 3 cannot effectively resist bending of the acoustic-magnetic anti-theft tag. If the length of the hard member 3 is too long relative to the length of the box 20, on one hand, the material cost of the hard member 3 is increased and the size of the length of the bag body 1 cannot be reduced indirectly, and on the other hand, the too long length of the hard member 3 may affect the bending resistance thereof, so as to affect the bending resistance of the hard member 3 on the acoustic-magnetic anti-theft tag.
In the above embodiment, the bag body 1 is a cloth bag, for example, so that the acoustic magnetic anti-theft label bag can be sewn on soft goods (such as clothes, shoes, handbags, etc.). Of course, the bag body 1 may also be a leather bag with certain toughness, or even a cut-proof plastic bag, and the like, and is not limited specifically herein.

In the above embodiment, the ratio of the length of the case 20 to the width of the case 20 is, for example, 1.5 to 10; the ratio of the thickness of the box body 20 to the width of the box body 20 is 0.05-0.5. Thus, the length, width and thickness of the box body 20 are small, so that the acoustic magnetic anti-theft tag can be small.
In the above embodiments, the resonant frequency of the acoustic magnetic anti-theft tag is, for example
57.5kHz-58.5 kHz. Of course, the resonant frequency of the acoustic magnetic anti-theft tag may also be less than 57.5kHz or greater than 58.5kHz, which is not particularly limited herein.
