Abstract

An electronic wind instrument includes a breath sensor, an operating element, a speaker, and an acoustic tube. The operating element receives an instruction related to a pitch. The speaker outputs a sound based on musical performance information obtained from at least one of the breath sensor and the operating element. The speaker has an inner space therein. The acoustic tube that has an inner space therein. The inner space of the acoustic tube is continuous with the inner space of the speaker. The acoustic tube extends in a direction away from the speaker.

First claim

What is claimed is:

1. An electronic wind instrument comprising:
a breath sensor;
an operating element that receives an instruction related to a pitch;
a speaker that outputs a sound based on musical performance information obtained from at least one of the breath sensor and the operating element, the speaker having an inner space therein; and
an acoustic tube that has an inner space therein, the inner space of the acoustic tube being continuous with the inner space of the speaker, the acoustic tube extending in a direction away from the speaker, wherein
the sound based on the musical performance information is directly radiated to an outside of the speaker and is radiated to an outside of the electronic wind instrument from an opening end of the acoustic tube through an inner space of the acoustic tube.

2. The electronic wind instrument according to claim 1 , wherein the operating element is provided on the acoustic tube.

3. The electronic wind instrument according to claim 1 , wherein
the acoustic tube includes:
a first tube part that includes a first end connected to the speaker and a second end spaced apart from the first end; and
a second tube part connected to the second end of the first tube part, wherein
the operating element is provided on the first tube part.

4. The electronic wind instrument according to claim 3 , wherein the second tube part includes metal.

5. The electronic wind instrument according to claim 1 , further comprising: a mouthpiece fixing part configured to fix a mouthpiece, wherein
the mouthpiece fixing part is fixed to the speaker.

6. The electronic wind instrument according to claim 5 , wherein the speaker is positioned between the mouthpiece fixing part and the operating element.

7. The electronic wind instrument according to claim 1 , further comprising: a casing that surrounds an outer peripheral surface of the acoustic tube and is spaced from the outer peripheral surface of the acoustic tube.

8. The electronic wind instrument according to claim 7 , further comprising: a circuit board that is provided in a clearance defined between the outer peripheral surface of the acoustic tube and the casing.

9. The electronic wind instrument according to claim 8 , wherein the circuit board is connected to at least one of the breath sensor, the operating element, and the speaker.
