Abstract

An ultra-low profile vibrating transducer, particularly suited for floor mat and ultra thin vibrating pad and multimedia tactical feedback applications, using an “I” core coil in the center and permanent magnets positioned at both ends of the “I” core to create balanced push-pull vibrating actions. Mounting methods to effectively transfer energy to the users while withstanding user'"'"'s body weight. “I” core coil may be driven by AC power, pulsed and/or DC power or audio power. Elastomeric supports are configured to provide rotational leverage action to further enhance the vibrating effectiveness.
