Abstract

An input device includes an input unit having at least one button arranged to produce a sound signal when pressed, a sound collector for collecting the sound signal produced from the button, a memory for storing control command information corresponding to a frequency of the sound signal produced from the button, and a controller for determining a control command corresponding to the frequency of the sound signal produced from the button based on the information stored in the memory, and for sending the control command to a subject to be controlled.

First claim

What is claimed is:

1. An input device comprising:
an input unit having at least one button arranged to produce a sound signal when pressed;
a sound collector for collecting the sound signal produced from the button;
a memory for storing control command information corresponding to a frequency of the sound signal produced from the button; and
a controller for determining a control command corresponding to the frequency of the sound signal produced from the button based on the information stored in the memory, and for sending the control command to a subject to be controlled,
wherein the button comprises:
a button frame that constitutes the body of the button;
a button guide that supports the button frame and has a fixer installed on the inner side of the button guide;
a pressing shaft installed to protrude backward from the rear side of the button frame and having a projection located on a side of the pressing shaft; and
a restoring spring that elastically supports the button frame against the button guide, and
wherein the projection is formed to produce a sound signal by coming into contact with the fixer as the pressing shaft is moving along a first axis.

2. The input device of claim 1 , wherein the button is formed to produce a preset sound signal.

3. The input device of claim 1 , wherein the input unit comprises
a first button to produce a first sound signal; and
a second button to produce a second sound signal with a different frequency from that of the first sound signal.

4. The input device of claim 1 , wherein the button is removably located.

5. The input device of claim 1 , wherein the controller determines a control command corresponding to a frequency of a sound signal produced from the button based on the information stored in the memory regardless of where the button is located, and sends the control command to the subject to be controlled.

6. The input device of claim 1 , wherein the controller converts the sound signal collected by the sound collector to a frequency signal, and classifies the frequency signal by frequency region.

7. The input device of claim 6 , wherein the controller determines that the input sound signal has a frequency of a classified region if the magnitude of the classified frequency signal exceeds a first threshold.

8. The input device of claim 6 , wherein the controller, if frequency signals are detected in a plurality of frequency regions, and the respective magnitudes of the detected frequency signals exceed a first threshold, classifies the input sound signal as noise.

9. A vehicle, comprising:
an input device, wherein the input device comprises
an input unit having at least one button arranged to produce a sound signal when pressed;
a sound collector for collecting the sound signal produced from the button;
a memory for storing control command information corresponding to a frequency of the sound signal produced from the button; and
a controller for determining a control command corresponding to the frequency of the sound signal produced from the button based on the information stored in the memory, and for sending the control command to a subject to be controlled,
wherein the button comprises:
a button frame that constitutes the body of the button;
a button guide that supports the button frame and has a fixer installed on the inner side of the button guide;
a pressing shaft installed to protrude backward from the rear side of the button frame and having a projection located on a side of the pressing shaft; and
a restoring spring that elastically supports the button frame against the button guide, and

wherein the pressing shaft is formed to produce a sound signal when the projection comes into contact with the fixer as the pressing shaft is moving along a first axis.

10. The vehicle of claim 9 , wherein the button is formed to produce a preset sound signal.

11. The vehicle of claim 9 , wherein the input unit comprises
a first button to produce a first sound signal; and
a second button to produce a second sound signal with a different frequency from that of the first sound signal.

12. The vehicle of claim 9 , wherein the button is removably located.

13. The vehicle of claim 9 , wherein the controller determines a control command corresponding to a frequency of a sound signal produced from the button based on the information stored in the memory regardless of where the button is located, and sends the control command to the subject to be controlled.
