Mute-able input device with keystroke tactile feedback

An input feedback method applicable to an input device and an output device directly or indirectly coupled with each other, the input device comprising at least one key, a tactile structure of the at least one key adjustably interfering with an operation path of the at least one key to provide a tactile feedback when the at least one key is in a first tactile mode and a mute-on mode, the method comprising:

• in the first tactile mode, a switching unit of the input device generating a switching signal involving a mode switching of the at least one key between different tactile modes;
• in response to the mode switching, an adjusting mechanism of the input device adjusting an interference ratio of the tactile structure to the operation path to enable the at least one key to enter a second tactile mode while the at least one key remains in the mute-on mode;
• the at least one key generating an input signal when being pressed and triggered;
• and
• independently from the tactile structure and/or the sound-generating structure, the output device outputting a second operation feedback according to the switching signal when the at least one key is triggered in the second tactile mode.

An input device, comprising:

• a plurality of keys, each of the keys having a tactile structure and a sound-generating structure to respectively generate a tactile feedback and an operating sound when the key is pressed;
• a plurality of adjusting mechanisms, each of the adjusting mechanisms having an adjusting portion corresponding to a corresponding one of the keys;
• and
• at least one switching unit having an operating portion and a switch member, the operating portion coupled to the switch member and the adjusting mechanisms, the switch member capable of generating a switching signal involving a mode switching of the keys between different tactile modes and/or different sound modes,
• wherein when the operating portion receives a force to move, the switch member is triggered to achieve the mode switching;
• meanwhile, for each of the keys, the adjusting mechanism moves with the operating portion to enable the adjusting portion to interfere with at least one of the tactile structure and the sound-generating structure.
