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.

Dependent claims

A vibrating massager comprising:

first electronic pulse generating means for forming a first series of electrical pulses, wherein said first electronic pulse generating means includes adjustment means for varying each first variable time occurring between a pulse transition in a first direction and a next pulse transition occurring in a direction opposite said first direction, while each time occurring between a pulse transition opposite said first direction and a next pulse transition occurring in said first direction remains constant;
vibration generating means for producing mechanical vibrations, said vibration generating means being driven according to said first series of electrical pulses, wherein said vibration generating means is turned on by said electrical pulses during pulse transitions opposite said first direction, and wherein said vibration generating means is turned off during pulse transitions in said first direction, whereby variation of said adjustment means varies each time delay during which said vibration generating means is turned off between times in which said vibration generating means is turned on while said vibration generating means is left on for a constant pulse duration;
and
a housing, surrounding said first electronic pulse generating means and said vibration generating means, transmitting mechanical vibrations produced by said vibration generating means to a protrusion forming a closed integral part of said housing, said protrusion extending outward from a surrounding exterior surface of said housing.

vibration generating means including a motor spinning an eccentric weight for producing mechanical vibrations;
a housing, surrounding said vibration generating means, transmitting mechanical vibrations produced by said vibration generating means to a protrusion forming an integral portion of said housing, said protrusion extending outward from a surrounding exterior surface of said housing;
and
speed control means for varying a rotational speed of said motor, wherein said speed control means includes first and second timing circuits, connected so that an output of said first timing circuit forms an input to said second timing circuit, and motor switching means connected to an output of said second timing circuit;
