Abstract
A vibrating massager includes a housing and an elastic strap, which is fastened into a loop to hold a protrusion extending from a surface of the housing against a pressure point of the human body. Mechanical vibrations, produced by a small electric motor spinning an eccentrically mounted weight, are transmitted to the protrusion. The motor is driven according to a pattern of pulses, between which the vibrations are interrupted. The length of time between vibrating pulses is adjusted with a first know on the device. The speed of the motor is adjusted using a second knob on the device, varying the frequency and amplitude of the vibrations. An extension strap is used to facilitate attachment of the strap around larger body members such as the head, as well as around smaller body members, such as the wrist.
