Abstract

There is provided a headrest with speakers capable of exhibiting an excellent sound effect. The headrest with speakers includes: a headrest frame; a pair of left and right enclosures supported by the headrest frame; speaker units supported in the enclosures respectively; and a headrest cushion member supported by the headrest frame to support a head, the headrest cushion member including: a net member having a pair of left and right acoustically transparent parts at places substantially facing the respective speaker units; and soundproof parts disposed between the pair of left and right acoustically transparent parts in the net member and between the pair of left and right enclosures respectively.

First claim

What is claimed is:

1. A headrest with speakers comprising:
a headrest frame;
a pair of left and right enclosures supported by the headrest frame;
speaker units supported in the enclosures respectively; and
a headrest cushion member supported by the headrest frame to support a head, the headrest cushion member including: a net member having a pair of left and right acoustically transparent parts at places substantially facing the respective speaker units; and soundproof parts disposed between the pair of left and right acoustically transparent parts in the net member and between the pair of left and right enclosures respectively,
wherein the net member is a three-dimensional knitted fabric,
wherein the net member is provided with a predetermined tension in a plane direction along a surface of the three-dimensional knitted fabric, and
wherein part of the headrest cushion member including the net member is in contact with the pair of left and right enclosures, and each of the enclosures together with the headrest frame functions as a skeletal frame member to support the headrest cushion member.

2. The headrest with speakers according to claim 1 , wherein the acoustically transparent parts and the soundproof part formed by polyurethane foam injected located between the pair of left and right acoustically transparent parts in the net member are integrally formed.

3. The headrest with speakers according to claim 1 , wherein the soundproof parts are each formed by using at least one of a sound insulating material and a sound absorbing material.

4. The headrest with speakers according to claim 3 , wherein the soundproof parts are each formed by using polyurethane foam.

5. The headrest with speakers according to claim 1 , wherein enclosures are made of iron-based metal.
