Abstract: An ultrasonic welding structure includes a welding plane and an energy-directing edge. The welding plane is formed on a first object or a second object. The energy-directing edge is formed on the first object or the second object and corresponds in position to the welding plane. The welding plane is oblique to a lamination direction of an ultrasonic device. The first object and the second object are welded together by ultrasonic welding which requires laminating the first object to the second object in the lamination direction so as for the energy-directing edge to exert a contact pressure upon the welding plane. Due to the welding plane and the energy-directing edge, ultrasonic welding thus performed requires less welding area and alignment structure than are taught by the prior art and is conducive to miniaturization of mobile electronic products.
