1. An input device directly or indirectly coupled to an output device, the input device comprising:
at least one key having a tactile structure and a sound-generating structure adjustably interfering with an operation path of the at least one key to respectively generate a tactile feedback and an operating sound;
a switching unit having an operating portion operable by a user, the switching unit capable of generating a switching signal involving a mode switching of the at least one key between different tactile modes and/or different sound modes; and
an adjusting mechanism having at least one adjusting portion adapted to move in response to the mode switching to drive the tactile structure and/or the sound-generating structure, so as to adjust an interference ratio of the tactile structure and/or the sound-generating structure to the operation path,
wherein after the mode switching occurs, independently from the tactile structure and/or the sound-generating structure, the output device is enabled to output an operation feedback according to the switching signal as the at least one key is triggered.
