Abstract:
A crystal and an ultrasonic welding method for a crystal. The crystal is used to close a top of a case of a portable object, the crystal being made of a transparent plastic material and being secured to the case of the portable object by ultrasonic welding. The crystal includes a top surface and a bottom surface that carry one or more conductive paths made of a transparent conductive material, and a peripheral rim that extends along at least one portion of the perimeter of the crystal. The peripheral rim provides at least one surface for the ultrasonic welding of the crystal to the case of the portable object.
