Patent ID: 7141029

Claim:
A vibratory exercise apparatus comprising: a vertical vibrator including lower and upper magnets which are disposed at a predetermined distance so that mutually magnetic poles oppose each other, for generating a non-alternating magnetic field; a first yoke integrally having a loop-type circulating circuit portion extended from a lower surface of the lower magnet to an upper surface of the upper magnet and an extension portion which is extended perpendicularly upwards at a constant gap from the lower-inner circumferential surface of the lower magnet; a second yoke which connects between the lower and upper magnets and whose inner circumferential surface forms a magnetic gap between the second yoke and the extension portion of the first yoke; a driving coil which generates an alternating magnetic field when an electrical driving signal is applied, and that is disposed in the magnetic gap so as to be displaced up and down according to a mutual action with the non-alternating magnetic field generated from the lower and upper magnets; and a cylindrical bobbin around the cylindrical portion of which the driving coil is wound; a joint whose one end is coupled with the upper portion of the bobbin; a vibration plate which is coupled with the other end of the joint; a base on one surface of which the vertical vibrator is installed; a guide, both ends of which are connected with the vibration plate, respectively, and which guides vertical movement of the vibration plate; and a vibration absorption unit which limits a range of movement of the vibration plate when the vibration plate moves vertically, and absorbs impact when the vibration plate descends.
