    摘要: A piezoelectric ceramic loudspeaker headphone structure includes a positioning frame, a steel sheet and a vibrating member. A step portion is disposed in an inner edge at the rear of the positioning frame. The steel sheet has an area approximately equal to that of the positioning frame and is disposed with a sound-making member stacked by a plurality of ceramic material layers. A lead wire is welded to the sound-making member. The vibrating member is a sheet body and has an area approximately equal to that of the step portion of the positioning frame. The steel sheet is disposed at a front edge of the positioning frame. The vibrating member is embedded in the step portion of the positioning frame, and thus a sound-making module is formed. The sound-making module is assembled to a headphone, and after the sound-making member receives an audio signal, a sound is guided out through response of the vibrating member. Therefore, the headphone is free of magnetism without influencing electronic products such as i-pad, i-phone, mobile phones or notebook computers, and is thinned due to omitting voice coils, which thus can be conveniently carried along.

    摘要: An optical transmission module comprising at least a photoelectric element, a printed circuit board and a flexible printed circuit board is provided. The flexible printed circuit board electrically connects the photoelectrical elements and the printed circuit board. At least a ground plane is formed on the flexible printed circuit board to reduce crosstalk and electromagnetic interference. Transmission lines and impedance formed on the flexible printed circuit board solve the problems of signal distortion and impedance mismatch. The flexible printed circuit board also serves as a flexible interface to solve prior problems of connection stress between the photoelectric element and the printed circuit board.
