Abstract
A stylus includes a tube body, a touch end connected to the tube body, an inflatable balloon enwrapping the tube body such that the tube body and the balloon cooperatively define a sealed chamber, and an inflating mechanism for inserting gas into the sealed chamber to inflate the balloon and therefore, the size of the stylus is adjustable and convenient for using.
Claims20
1 A stylus, comprising:
- a tube body;
- a touch end connected to the tube body;
- an inflatable balloon enwrapping the tube body such that tube body and the balloon cooperatively define a sealed chamber;
- and
- an inflating mechanism for inserting gas into the sealed chamber to inflate the balloon.
The stylus of claim 1, wherein the stylus further comprises a gas intake through which the inflating mechanism inserts gas into the sealed chamber and a gas outlet through which the gas may be vented out of the sealed chamber to allow the balloon to return to an original shape.
The stylus of claim 1, wherein the tube body is a substantially hollow metallic cylinder, and defines a gas conduit extending therethrough and a hole communicating the gas conduit and the sealed chamber.
The stylus of claim 1, wherein the balloon is made of rubber, latex, polychloroprene, or nylon fabric.
The stylus of claim 1, wherein the balloon is substantially pipe-shaped.
An electronic device, comprising:
- a main body defining an accommodating hole;
- a touch panel mounted on the main body;
- and
- a stylus received in the accommodating hole, the stylus comprising:
- a tube body;
- a touch end connected to the tube body;
- an inflatable balloon enwrapping the tube body such that tube body and the balloon cooperatively define a sealed chamber;
- and
- an inflating mechanism for inserting gas into the sealed chamber to inflate the balloon.
An electronic device, comprising:
- a stylus;
- a main body defining an accommodating hole to receive the stylus;
- and
- a touch panel mounted on the main body;
- wherein the stylus comprising:
- a tube body;
- a touch end connected to the tube body;
- an inflatable balloon enwrapping the tube body such that tube body and the balloon cooperatively define a sealed chamber;
