Abstract

An electronic musical instrument includes: a contact sensor that generates lip detection information from an operation by a performer; and a controller that derives a lip contact area from the lip detection information generated by the contact sensor, and performs musical note control of an electronic sound source in accordance with the derived lip contact area.

First claim

What is claimed is:

1. An electronic musical instrument, comprising:
a contact sensor that generates lip detection information from an operation by a performer; and
a controller that derives a lip contact area from the lip detection information generated by the contact sensor, and performs musical note control of an electronic sound source in accordance with the derived lip contact area,
wherein the contact sensor includes a tongue detector that detects a contact of a tongue of the performer, and
wherein, based on whether the contact of the tongue occurs or not, the controller performs musical note control that is different from the musical note control of the electronic sound source based on the lip contact area.

2. The electronic musical instrument according to claim 1 , further comprising:
a force detector that detects a force applied to the contact sensor,
wherein the controller performs said musical note control of the electronic sound source in accordance with the force applied to the contact sensor detected by the force detector as well as the lip contact area.

3. The electronic musical instrument according to claim 1 , further comprising:
a distance detector that detects a distance to the contact sensor from a reference point that changes due to a warp of the contact sensor, and
wherein the controller performs said musical note control of the electronic sound source in accordance with the distance to the contact sensor detected by the distance detector as well as the lip contact area.

4. The electronic musical instrument according to claim 1 , wherein said musical note control by the controller includes musical note control of the electronic sound source with respect to one or more among a tone, a volume, and a pitch of a sound to be generated by the electronic sound source.

5. The electronic musical instrument according to claim 2 ,
wherein said musical note control by the controller includes control of the electronic sound source with respect to a tone, a volume and a pitch of a sound to be generated by the electronic sound source, and
wherein one or two among the tone, the volume, and the pitch are controlled based on the lip contact area, and the remaining one or two among the tone, the volume, and the pitch are controlled based on the detected force applied to the contact sensor.

6. An electronic musical instrument, comprising:
a contact sensor having a capacitive touch sensor that detects a contact of a lip of a performer; and
a controller that performs musical note control of an electronic sound source in accordance with information detected by the capacitive touch sensor.

7. The electronic musical instrument according to claim 6 ,
wherein the contact sensor detects the lip of the performer and generates lip detection information, and
wherein the controller derives at least one of a lip contact position and a lip contact area from the lip detection information generated by the contact sensor and performs musical note control of the electronic sound source in accordance with said at least one of the lip contact position and the lip contact area that has been derived.

8. The electronic musical instrument according to claim 7 ,
wherein the contact sensor includes a tongue detector that detects a contact of a tongue of the performer, and
wherein, based on whether the contact of the tongue occurs or not, the controller performs musical note control that is different from the musical note control of the electronic sound source based on the lip contact area.

9. The electronic musical instrument according to claim 6 , further comprising:
a force detector that detects a force applied to the contact sensor,
wherein the controller performs said musical note control of the electronic sound source in accordance with the force applied to the contact sensor detected by the force detector as well as the information detected by the capacitive touch sensor.

10. The electronic musical instrument according to claim 6 , further comprising:
a distance detector that detects a distance to the contact sensor from a reference point that changes due to a warp of the contact sensor, and
wherein the controller performs said musical note control of the electronic sound source in accordance with the distance to the contact sensor detected by the distance detector as well as the information detected by the capacitive touch sensor.

11. The electronic musical instrument according to claim 6 , wherein said musical note control by the controller includes control of the electronic sound source with respect to one or more among a tone, a volume, and a pitch of a sound to be generated by the electronic sound source.

12. The electronic musical instrument according to claim 9 ,
wherein said musical note control by the controller includes control of the electronic sound source with respect to a tone, a volume and a pitch of a sound to be generated by the electronic sound source, and
wherein one or two among the tone, the volume, and the pitch are controlled based on the information detected by the capacitive touch sensor, and the remaining one or two among the tone, the volume, and the pitch are controlled based on the force applied to the contact sensor detected by the force detector.

13. The electronic musical instrument according to claim 10 ,
wherein said musical note control by the controller includes control of the electronic sound source with respect to a tone, a volume and a pitch of a sound to be generated by the electronic sound source, and
wherein one or two among the tone, the volume, and the pitch are controlled based on the information detected by the capacitive sensor, and the remaining one or two among the tone, the volume, and the pitch are controlled based on the distance to the contact sensor detected by the distance detector.

14. An electronic musical instrument, comprising:
a contact sensor having a capacitive touch sensor;
a controller that performs musical note control of an electronic sound source in accordance with information detected by the capacitive touch sensor; and
a distance detector that detects a distance to the contact sensor from a reference point that changes due to a warp of the contact sensor,
wherein the controller performs said musical note control of the electronic sound source in accordance with the distance to the contact sensor detected by the distance detector as well as the information detected by the capacitive touch sensor.

15. The electronic musical instrument according to claim 14 ,
wherein said musical note control by the controller includes control of the electronic sound source with respect to a tone, a volume and a pitch of a sound to be generated by the electronic sound source, and
wherein one or two among the tone, the volume, and the pitch are controlled based on the information detected by the capacitive sensor, and the remaining one or two among the tone, the volume, and the pitch are controlled based on the distance to the contact sensor detected by the distance detector.

16. An electronic musical instrument, comprising:
a contact sensor having a capacitive touch sensor;
a controller that performs musical note control of an electronic sound source in accordance with information detected by the capacitive touch sensor; and
a force detector that detects a force applied to the contact sensor,
wherein the controller performs said musical note control of the electronic sound source in accordance with the force applied to the contact sensor detected by the force detector as well as the information detected by the capacitiv
