Acoustic device
The present invention is directed to reducing influence of crosstalk components by appropriately blocking a propagation path of the crosstalk components output from speakers that reproduce signals for right and left ears respectively. Provided is a contact member used in contact with a back and/or a back of a head of a listener. The contact member is installed with: a first speaker that reproduces a signal for the left ear and a second speaker that reproduces a signal for the right ear; and a propagation obstruction adapted to block a propagation path of crosstalk components output from the respective speakers.
1. An acoustic device comprising
a contact member used in contact with a back and/or a back of a head of a listener, wherein
the contact member is installed with:
a first speaker configured to reproduce at least one or more signals for a left ear and a second speaker configured to reproduces at least one or more signals of a right ear; and
a propagation obstruction configured to block a propagation path of crosstalk: components output from the first speaker and the second speaker, wherein
the propagation obstruction is installed at the contact member in a manner such that a position of the propagation obstruction can be adjusted, and
the position of the propagation obstruction can be adjusted at least in a first direction along the contact member, a second direction substantially perpendicular to the first direction, or a third direction connecting the first speaker and the second speaker.
2. The acoustic device according to claim 1 , wherein
the contact member includes one member, and
the first speaker, the second speaker, and the propagation obstruction are installed at the one member.
3. The acoustic device according to claim 2 , wherein
the one member includes a seat or a headrest.
4. The acoustic device according to claim 1 , wherein
the contact member is formed by connecting two members, and
the first speaker and the second speaker are installed at one of the two members, and the propagation obstruction is installed at another member of the two members.
5. The acoustic device according to claim 4 , wherein
the two members include the seat and the headrest.
6. The acoustic device according to claim 1 , wherein
the propagation obstruction is detachably installed at the contact member.
7. The acoustic device according to claim 1 , wherein
the propagation obstruction includes a sound-absorbing material.
8. The acoustic device according to claim 1 , wherein
the propagation obstruction includes a shape fitting material.
9. The acoustic device according to claim 1 , wherein
the propagation obstruction has a shape integrated with the contact member.
