Abstract

In a headrest including a core member, an acoustic speaker, and an acoustic microphone, the acoustic microphone is provided in a recessed portion provided in the core member, and a sound collection surface of the acoustic microphone is provided in a position rearward of a vibrating surface of the acoustic speaker. An opening at a tip end of the recessed portion can be provided in a position forward of a tip end of the vibrating surface of the acoustic speaker. The recessed portion can be formed into a shape that narrows from the opening toward a bottom surface. Even when the acoustic microphone is provided near to the acoustic speaker, accuracy of voice recognition by the acoustic microphone can be prevented from being reduced.

First claim

The invention claimed is:

1. A headrest comprising:
a core member;
an acoustic speaker; and
an acoustic microphone,
wherein the acoustic microphone is provided in a recessed portion provided in the core member, and
a sound collection surface of the acoustic microphone is provided in a position rearward of a vibrating surface of the acoustic speaker,
wherein an opening at a tip end of the recessed portion is located in a position forward of a tip end of the vibrating surface of the acoustic speaker.

2. The headrest according to claim 1 , wherein the recessed portion has a shape that narrows from the opening toward a bottom surface.

3. The headrest according to claim 1 , wherein an inner wall of the recessed portion is formed of a material to which flock coating is applied.

4. The headrest according to claim 3 , wherein the tip end of the recessed portion juts out to an outside of the core member, and the flock coating is also applied to the jutting portion.

5. The headrest according to claim 1 , wherein an inner wall of the recessed portion is formed of a material to which rubber coating is applied.

6. The headrest according to claim 5 , wherein the tip end of the recessed portion juts out to an outside of the core member, and the rubber coating is also applied to the jutting portion.

7. The headrest according to claim 1 , wherein an inner wall of the recessed portion is formed of a material to which emboss processing is applied.

8. The headrest according to claim 7 , wherein the tip end of the recessed portion juts out to an outside of the core member, and the emboss processing is also applied to the jutting portion.

9. A vehicle seat comprising:
a seat cushion that receives a hip of a seated person;
a seat back that receives a back of the seated person; and
a headrest that receives a head of the seated person,
wherein the headrest includes a core member, an acoustic speaker, and an acoustic microphone,
wherein the acoustic microphone is provided in a recessed portion provided in the core member, and
a sound collection surface of the acoustic microphone is provided in a position rearward of a vibrating surface of the acoustic speaker,
wherein an opening at a tip end of the recessed portion is located in a position forward of a tip end of the vibrating surface of the acoustic speaker.

10. A headrest comprising:
a core member;
an acoustic speaker; and
an acoustic microphone,
wherein the acoustic microphone is provided in a recessed portion provided in the core member, and
a sound collection surface of the acoustic microphone is provided in a position rearward of a vibrating surface of the acoustic speaker,
wherein a wall surface of the recessed portion that connects an opening at a tip end of the recessed portion and a bottom surface of the recessed portion is linear.
