Patent ID: 8092405

Claim:
An apparatus comprising: a vibration barrel comprising: a vibration motor; a power source for the vibration motor; an exterior elastomeric band consisting of a vibration barrel case that houses the vibrator barrel within the vibration barrel case; and a flat loop; wherein the longitudinal axis of the flat loop and the longitudinal axis of the vibration barrel case retaining the vibration barrel are parallel and spaced apart; the vibration barrel is further comprised of a plurality of battery cells; a switching means for engaging only one battery cell for lower rates of vibration and engaging two battery cells for higher rates of vibration; the switching means further comprises a protrusion for: contacting a first metal strip that causes current to flow from a first battery to the vibration motor resulting in the vibration of the apparatus under the power of one battery; and contacting a second metal piece that causes current to flow from a first battery to the vibration motor and from a second battery to the vibration motor resulting in the vibration of the apparatus under the power of two batteries.
