An organic electroluminescence module capable of reducing a processing loss of wiring boards for supplying power to an anode and a cathode is provided. An implant is positioned within at least a portion of the tongue and may be secured to other surrounding structures such as the mandible andor hyoid bone. The diverger may be located at an end of an optical fiber feed, or between a pair of optical fibers. The actuator controller adjusts the driving frequency based at least in part on the determined operational mechanical resonant frequency. A thermal expansion absorber is disposed on an external surface of the end plates for absorbing thermal expansion in the axial direction of the tie rod.
