Abstract
The present disclosure relates to a stylus pen. The stylus pen according to the present disclosure includes: a housing; a resonance circuit unit accommodated in an internal space of the housing, including an inductor unit and a capacitor unit electrically connected to the inductor unit, and configured to resonate in response to a magnetic signal generated by a touch screen; and a magnetic field blocking unit surrounding at least a partial portion of the resonance circuit unit, and including a magnetic material.
Claims15
A stylus pen, comprising:
- a housing;
- a tip at least partially exposed to the outside of the housing;
- a resonance circuit unit accommodated in an internal space of the housing, including an inductor unit and a capacitor unit electrically connected to the inductor unit, and configured to resonate in response to a magnetic signal generated by a touch screen;
- and
- a magnetic field blocking unit surrounding at least a partial portion of the resonance circuit unit, and including a magnetic material,
- wherein the housing includes a first region surrounding the inductor unit and a second region surrounding the tip, and at least a partial portion of the inductor unit;
- wherein the magnetic field blocking unit includes a first blocking portion where the magnetic material is coated on at least one of an inner surface and an outer surface of the first region, and a second blocking portion where the magnetic material is coated on at least one of an inner surface and an outer surface of the second region;
- and
- wherein the inductor unit is adjacent the tip.
