  • a rotary motor with an eccentric mass attached to a shaft is employed.
  • the rotation of the eccentric mass about the axis of the motor creates the vibrator effect, the speed of rotation establishing the frequency of vibration.
  • the motor and mass preferably are contained in an enclosure to shield the rotating members from disturbance.
  • the degree of force can be tuned by adjusting or selecting the following parameters: speed (frequency of oscillation) amount of eccentric mass, degree of offset of mass from centerline and amount of moving mass.
  • the orientation of the motor axis can be either perpendicular or parallel to the skin surface.
  • the mass, the geometry and the frequency of operation of the system can be optimized to take advantage of resonant effects which will beneficially amplify the input frequency to achieve higher amplitudes and massaging force.
  • An example of a vibratory system includes commercially available vibratory elements, such as low voltage direct current (dc) motors with eccentric weights that are designed for commercial products such as mobile phones, electric tooth brushes, toy vehicles, and massagers.

  • the power source can be a single-use battery, such as either button cell shaped or cylindrical cell shaped or flat-pouch encapsulated battery based on any chemical composition known in the art, including manganese-zinc, metal hydride, lithium, lithium ion, lithium polymer, and other known battery chemistries. Voltage of the battery can range from 1 volts to 3 volts to 12 volts depending on the motor employed. The battery capacity is selected to provide for sufficient time of operation of the vibrating element as described above. Suitable power sources can include primary batteries and secondary (rechargeable) batteries, fuel cells, hydrocarbon fuel cells, printed batteries, and plug- in power sources. In one embodiment, the power source for the vibratory component must have adequate energy density for the vibratory component to vibrate for up to 8 hours, e.g. up to 10 hours, e.g. up to 12 hours.
  • the vibratory element can be activated by completing an electrical circuit with the power source. In certain embodiments, this can be achieved by means of a pull-out tab separating two contacts thus closing the electric circuit and activating the vibrating element, as known in the art. This prevents electrical communication during shipping and storage of the device, but allows electrical communication when removed by the user.
  • the activation of the vibratory element can be achieved by a magnet-based actuator, such as magnet-sensitive proximity switch, by an electric switch, or similar electric circuit activation element.
  • the vibratory element or thermal device can also optionally incorporate a time-controller, which will switch the vibration off after a pre-set period of time, for example after 20 minutes or 30 minutes or after 1 hour.
  • the vibratory element may have extensions connected from a central vibratory source that delivers the vibratory sensation over a portion of the surface of the device or over the entire surface of the device, as a means for increasing the surface area of the vibratory sensation over the skin. These extensions may be present as fingers or plates. A vibratory resonance may be incorporated between the source and the extensions to increase the force of the total vibration or to modulate the frequency of the vibration.
  • the vibratory element is operational for a relatively short time period, compared to the life of the thermal insert.
  • the vibratory element delivers a vibration for the initial 20 minutes to 30 minutes of operation, then stops. Short periods of vibration can enhance the perceived benefit from the heat, especially helping to loosen stiff muscles before the thermal insert reaches its maximum temperature.
  • the ratio of time for the vibratory element to the thermal insert is 1:50 or 1 :25 or 1 : 10 or 1 :5.
  • the noise level depends upon the vibrational frequency, the damping provided by the skin of the user or the enclosure; the mass of the vibrational element and eccentric distance traveled by the eccentric mass on the rotary motor.
  • the device is substantially inaudible to the patient while delivering vibration.
  • the frequency of vibration is preferably below about 150 Hz, for example below about 20 Hz., however higher frequencies up to about 10,000 Hz can be utilized as the noise is somewhat dampened by the vibrating element being enclosed and being in contact with sound- dampening soft tissue and heating element.
  • Preferred amplitude and frequency ranges of vibration are selected to provide optional patient's relief and to utilize low cost, miniature vibrators.
  • the vibration can be sensed at the skin surface, but is substantially inaudible to the patient.
  • the frequency is from about 1 Hz to about 10,00 Hz, another embodiment from about 5 Hz to about 1,000 Hz, and in yet another embodiment, from about 1 Hz to about 100 Hz.
  • the amplitude of vibratory stimulation as measured on the surface of the device ranges from 0.1 mm peak-to- peak to 1 mm peak-to-peak and up to 15 mm peak-to-peak.
  • the human auditory system is sensitive to frequencies from about 20 Hz to a maximum of around 20,000 Hz, although the hearing range decreases with age.
  • the human ear is most sensitive between 1,000 Hz and 5,000 Hz, largely due to the resonance of the ear canal and the transfer function of the ossicles in the middle ear.
  • One desired function of the vibratory element is to create no perceptibly audible disturbance to the user.
  • Equal-loudness contours were first measured by Fletcher and Munson using headphones (1933). In their study, listeners were presented with pure tones at various frequencies and over 10 dB increments in stimulus intensity. For each frequency and intensity, the listener was also presented with a reference tone at 1000
  • the reference tone was adjusted until it was perceived to be of the same loudness as the test tone. Loudness, being a psychological quantity, is difficult to measure, so Fletcher and Munson averaged their results over many test subjects to derive reasonable averages. Based on these studies human hearing sensitivity was found to drop off dramatically below 100Hz.
  • the loudness of the noise from the vibratory element is preferably below 60 dB at a distance of 1 foot which is equivalent to human conversation, such as below 50 db at one foot, or below 20 db at 1 foot.
  • the voltage of the power supply is selected to be safe and to provide sufficient power to the vibratory element. Typically the voltage is from 1.5 V to 3 V, and in some embodiments up to 12 V DC.
