Abstract: An input device is provided. The input device includes an operation element, an optical finger navigation module, a press sensing circuit and a control unit. The optical finger navigation module senses a moving operation of the finger on the operation element so as to generate a motion signal, and the press sensing circuit is disposed under the optical finger navigation module and generates a press signal in response to a pressing operation of the finger. The control unit is electrically connected with the optical finger navigation module and the press sensing circuit, so as to generate a first control command in response to the motion signal and generate a second control command in response to the press sensing signal.

Abstract: A protecting device with keys' functions is provided. The protecting device includes a triggering member, a printed circuit board, and plural curable resinic structures. The printed circuit board includes plural first contacts. The plural first contacts are disposed on a top surface of the printed circuit board. The triggering member is disposed over the printed circuit board. The triggering member includes plural second contacts. The plural curable resinic structures are arranged between the triggering member and the printed circuit board for separating the plural first contacts and the plural second contacts from each other. Since the triggering member, the printed circuit board and the plural curable resinic structures of the protecting device of the present invention may replace the keys and the membrane switch circuit module of the conventional keyboard device, the thickness of the protecting device is largely reduced.

Abstract: A knob structure for adjusting a sound parameter is provided, which includes a knob, an encoder, an interference component and a switching module. The knob has a shaft portion and an internal teeth portion. The encoder is connected to the shaft portion of the knob, in which the encoder includes a turntable and a bottom plate. The turntable has one or more protrusions in contact with the bottom plate. When the knob is rotated to rotate the turntable of the encoder, the one or more protrusions rub against the bottom plate. The interference component has a first end adjacent to the internal teeth portion of the knob. The switching module is configured to make the first end of the interference component be in contact with or moved away from the internal teeth portion of the knob. A headphone including the knob structure is also provided.
