Abstract
An input device includes a cover and a base. The cover includes a button and a protrusion. The protrusion protrudes from the button. The base includes a processing unit and a button controlling module. The button controlling module includes a first magnetic member, a second magnetic member, and a movement sensing unit. The adjacent ends of the first magnetic member and the second magnetic member have the same polarity. The protrusion of the button contacts the first magnetic member. The movement sensing unit is for sensing the movement of the second magnetic member and for transmitting the sensed movement data of the second magnetic member to the processing unit. The processing unit determines the depressed button according to the sensed movement data of the second magnetic member.
Claims14
An input device, comprising:
- a cover comprising a first button, a second button, a first protrusion protruding from the first button, and a second protrusion protruding from the second button;
- a base:
- a processing unit;
- and
- a button controlling module comprising a first magnetic member, a second magnetic member, a third magnetic member, a carrier, and a movement sensing unit, the carrier defining a receiving space for slidably receiving the first, second, and third magnetic members, the second magnetic member being arranged between the first and third magnetic members, the first and second magnetic members having adjacent ends of the same polarity, and the third and second magnetic members having adjacent ends of the same polarity, wherein the first protrusion contacts the first magnetic member, and the second protrusion contacts the third magnetic member;
- the movement sensing unit senses movement of the second magnetic member and transmits the movement data of the second magnetic member to the processing unit;
- the processing unit determines which of the first and the second button is depressed according to the movement data.
An input device, comprising:
- a cover comprising at least one button, a protrusion protruding from each button;
- a base;
- a processing unit;
- and
- a button controlling module comprising at least one first magnetic member, at least one second magnetic member, a carrier, and a movement sensing unit, the carrier defining a receiving space for slidably receiving the at least one first magnetic member and the at lease one second magnetic member;
- the at least one first magnetic member and the at least one second magnetic member having the adjacent ends of the same polarity, the protrusion of each button contacting each first magnetic member, the movement sensing unit sensing the movement of the at least one second magnetic member and transmitting the movement data of the at least one second magnetic member to the processing unit;
- the processing unit determining which of the at least one button is depressed according to the movement data.
