Abstract

According to one aspect of the present invention, there is provided an audio system. The audio system includes a user computer to output a note; a musical instrument unit to transmit a first electrical signal to the user computer, and a user operation recognition device attached to or disposed at a specific part of the musical instrument unit to transmit a second electrical signal to the user computer. The user operation recognition device is to change or adjust a note of the musical instrument unit on the basis of a touch applied to the user operation recognition device. The user operation recognition device includes a substrate, and at least one unit cell including a first partial electrode formed along a first pattern on the substrate and a second partial electrode formed along a second pattern on the substrate.

Claims

1. An audio system, comprising:

a user computer to output a note;

a musical instrument unit to transmit a first electrical signal to the user computer; and

a user operation recognition device attached to or disposed at a specific part of the musical instrument unit to transmit a second electrical signal to the user computer,

wherein the user operation recognition device is to change or adjust a note of the musical instrument unit on the basis of a touch applied to the user operation recognition device, and

wherein the user operation recognition device comprises;

a substrate; and

at least one unit cell including a first partial electrode formed along a first pattern on the substrate and a second partial electrode formed along a second pattern on the substrate.

2. The audio system of claim 1, wherein the musical instrument unit is composed of a keyboard instrument, and the specific part is a keyboard.

3. The audio system of claim 2, wherein the touch is made in a longitudinal direction with respect to the specific part.

4. The audio system of claim 1, wherein the specific part consists of a single part, and the touch is a multi-touch made to the specific part.

5. The audio system of claim 1, wherein the specific part consists of multiple parts, and the touch is a multi-touch made to each of the parts.

6. The audio system of claim 1, wherein the changing of the note is at least one of a pitch change, a timbre change, and a modulation.

7. The audio system of claim 1, wherein the changing of the note is addition of a special effect.

8. The audio system of claim 1, wherein the adjusting of the note is volume adjustment.
