Abstract

A touch input device comprises a body having a plurality of hole portions; and a signal transfer unit formed in the body, wherein the signal transfer unit is provided to pass on the body between the hole portions adjacent thereto to recognize a user's touch signal.

First claim

What is claimed is:

1. A touch input device comprising:
a body having a plurality of holes; and
a signal transfer unit disposed in the body,
wherein the signal transfer unit is disposed on the body between the plurality of holes adjacent thereto to recognize a user's touch signal,
the plurality of holes define respective passages that allow air to pass through the body in a direction perpendicular to a surface of the body,
the body comprises a base including a metal complex and a pattern groove defined on one surface of the base,
the signal transfer unit includes a detection pattern disposed in the pattern groove,
the base comprises a first base and a second base laminated on the first base,
the pattern groove comprises a first pattern groove defined on one surface of the first base and a second pattern groove define on one surface of the second base to intersect the first pattern groove,
the detection pattern comprises a first detection pattern disposed on the first pattern groove and a second detection pattern disposed on the second pattern groove, and
the plurality of holes are arranged in respective regions partitioned by the first detection pattern and the second detection pattern.

2. The touch input device of claim 1 , wherein the body has a mesh shape, in which the plurality of holes are disposed, wherein a region of the body in which the signal transfer unit is disposed acts as a touch unit configured to receive an input a user's touch signal.

3. The touch input device of claim 1 , wherein the first pattern groove perpendicularly intersects the second pattern groove with respect to the second base.

4. The touch input device of claim 1 , wherein the base comprises a resin comprising any one or more of polycarbonate (PC), polyamide (PA), or acrylonitrile-butadiene-styrene copolymer (ABS) and a metal oxide comprising any one or more of Mg, Cr, Cu, Ba, Fe, Ti, or Al.

5. The touch input device of claim 1 , wherein the base is coated on one surface of one of resin, glass or leather.

6. The touch input device of claim 1 , wherein the second pattern groove is disposed on a rear surface of the base.

7. The touch input device of claim 1 , wherein the first detection pattern and the second detection pattern are apart from each other.

8. The touch input device of claim 1 , wherein the touch input device is any one of an air conditioning, a heater, or an air cleaner that allows air to pass through the plurality of holes.

9. The touch input device of claim 1 , wherein the touch input device is a speaker outputting sound via the plurality of holes.

10. The touch input device of claim 1 , wherein a region, of the body, in which the plurality of holes are disposed, comprises a concave surface or a convex surface.

11. The touch input device of claim 1 , wherein a width of the detection pattern is equal to or more than 25 μm and a distance between the detection patterns adjacent to each other is equal to or more than 30 μm.

12. The touch input device of claim 1 , wherein each of the plurality of holes extends from one outer surface to an opposing outer surface of the body.
