1. A key structure, comprising:
a base;
a movable mechanism movably positioned on the base;
a sound generating member positioned on the base, the sound generating member having a hitting portion extending corresponding to an impact surface; and
an adjusting unit movable relative to the base to be at a first position or a second position,
wherein when the adjusting unit is at the first position, and a pressing force is applied to the movable mechanism, the movable mechanism moves relative to the base and drives the sound generating member to move, so the hitting portion moves to hit the impact surface to generate a hitting sound; when the adjusting unit is at the second position, and the pressing force is applied to the movable mechanism, the adjusting unit restricts movement of the hitting portion, so the hitting portion cannot move to hit the impact surface.
