摘要： A method of making a magnetomechanical electronic article surveillance marker is provided that, in one embodiment, includes deposition or placing of at least one elongated bias magnet onto a substrate, depositing a cavity layer onto the substrate where the cavity layer defines an elongated cavity adjacent the bias magnet. Placing a magnetomechanical resonator into the cavity and sealing a cover onto the cavity layer wherein the resonator is captured in the cavity and free to mechanically vibrate substantially unencumbered. The substrate itself may be magnetic thereby eliminating a separate bias magnet. In an alternate embodiment, a cavity is molded in a plastic substrate sized to fit a resonator, and a cover is sealed to the substrate to capture a resonator in the cavity. At least one bias magnet is placed onto the cover adjacent the cavity and a second cover is sealed to the substrate, to the first cover, and to the bias fixing the bias in place adjacent the cavity.
