Sound pickup device and sound pickup method
A sound pickup device according to this embodiment includes a microphone part placed at a sound pickup position in close proximity to an ear hole without blocking an ear canal, and positioned so as to face outside of the ear canal, and a wire having flexibility and extending to the sound pickup position. Further, in this embodiment, at least part of the wire is formed along an auricle.
1. A sound pickup device comprising:
a microphone part placed at a sound pickup position inside an ear hole without blocking an ear canal, and positioned so as to face outside of the ear canal, the microphone part being smaller than the ear hole; and
a wire having flexibility to hold the microphone in air of the ear canal and configured to extend to the sound pickup position,
wherein the microphone part is placed at a leading end of the wire, and
wherein at least part of the wire is formed to be deformable to be fit a shape of a front side of an auricle so that the microphone part is not in contact with an outer ear.
2. The sound pickup device according to claim 1 , further comprising:
a hook part configured to hook on the auricle, wherein
the wire extends from one end of the hook part to the sound pickup position, and
the wire is formed along a groove of the auricle in a part of an area from the one end of the hook part to the sound pickup position.
3. The sound pickup device according to claim 2 , wherein
a length of the wire from the one end of the hook part to the sound pickup position is adjustable, and
a direction of the wire is adjustable at the one end of the hook part.
4. The sound pickup device according to claim 1 , wherein
the wire includes a curved part formed along an internal surface of an internal groove shape of the auricle to fit into the internal groove shape of the auricle, and
the wire is urged against the internal surface of the internal groove shape of the auricle by an urging force generated by the curved part.
5. The sound pickup device according to claim 1 , further comprising:
a hook part configured to hook on the auricle, wherein
the wire extends from one end of the hook part to the sound pickup position, and
the wire includes a curved part formed along an internal surface of an internal groove of the auricle and fitted into the internal groove of the auricle, the curved part formed between the one end of the hook part and the sound pickup position, wherein the wire is urged against the internal surface of the internal groove by an urging force generated by the curved part.
6. A sound pickup device comprising:
a first sound pickup unit configured to be worn on a left ear of a user;
a second sound pickup unit configured to be worn on a right ear of the user; and
a connection part configured to connect the first sound pickup unit and the second sound pickup unit, and generate an urging force in a direction where the first sound pickup unit and the second sound pickup unit come close to each other,
wherein each of the first and second sound pickup units includes
a microphone part configured to be placed at a sound pickup position inside an ear hole without blocking an ear canal, and positioned so as to face outside of the ear canal, the microphone part being smaller than the ear hole, and
a wire having flexibility to hold the microphone in air of the ear canal and configured to extend to the sound pickup position,
wherein at least part of the wire is formed to be deformable to fit a shape of a front side of an auricle so that the microphone part is not in contact with an outer ear,
wherein the microphone part is placed at a leading end of the wire.
7. A sound pickup method comprising:
a step of outputting a measurement signal from headphones while a user is wearing the sound pickup device according to claim 1 and is wearing the headphones over the sound pickup device; and
a step of picking up the measurement signal by the sound pickup device.
