no. 1 approach

[0042] First, the structure of the sound absorbing body will be described. figure 1 It is a schematic diagram which shows the structure of the sound absorbing body which concerns on this embodiment. The sound absorbing body 200 is a sound absorbing body mainly composed of fibers, and is, for example, attached to the surface of a casing member of the device to absorb (sound absorbing) noise emitted from the device. figure 1 (a) is a side sectional view. Such as figure 1 As shown in (a), in the thickness direction T of the cuboid-shaped sound absorbing body 200 , the density is different between one side and the other side, and the color is different between one side and the other side.

[0043] The sound absorbing body 200 according to this embodiment is formed of one piece (integrated), and the side 200 a of the sound absorbing body 200 in the thickness direction T is a dense part 210 with a high density, and the other side 200 b is a dense part 210 . The sparser portion 22...

[0063] Next, a second embodiment will be described.

[0064] First, the structure of the sound absorbing body will be described. image 3 It is a schematic diagram which shows the structure of the sound absorbing body which concerns on this embodiment. The sound absorbing body 201 is a sound absorbing body mainly composed of fibers, and is attached to, for example, the surface of a casing member of the device to absorb (sound absorbing) noise emitted from the device. image 3 (a) is a side sectional view. Such as image 3 As shown in (a), the density differs between one side and the other side in the thickness direction T of the cuboid-shaped sound absorbing body 201 , and the color varies between one side and the other side.

[0065] In the sound absorbing body 201 according to the present embodiment, the sound absorbing body 201 formed in one piece (integrated) in the thickness direction T has a dense portion 210 on one surface 201 a side, and a sparsely dense portion 220...

[0075] Next, a third embodiment will be described.

[0076] First, the structure of the sound absorbing body will be described. Figure 4 It is a schematic diagram which shows the structure of the sound absorbing body which concerns on this embodiment. The sound absorbing body 202 is a sound absorbing body mainly composed of fibers, and is attached to, for example, the surface of the device case member to absorb (sound absorbing) noise emitted from the device. Figure 4 (a) is a side sectional view. Such as Figure 4 As shown in (a), the density differs between one side and the other side in the thickness direction T of the cuboid-shaped sound absorbing body 202 , and the color varies between one side and the other side.

[0077] In the sound absorbing body 202 according to the present embodiment, the sound absorbing body 202 formed in one piece (integrated) in the thickness direction T is composed of a densely dense part 210 on the one side 202 a side, and is composed of a...

Abstract

The present invention provides a sound absorbing body which is easy to handle and has excellent sound absorbing properties, and a device using the sound absorbing body. The sound absorbing body is a sound absorbing body mainly composed of fibers, and the density of the sound absorbing body is different between one side and the other side in the thickness direction, and the color of the one side and the other side is different.

Description

technical field [0001] The invention relates to a sound absorbing body and equipment using the sound absorbing body. Background technique [0002] Conventionally, there has been known a multilayer sound-absorbing material in which a hard layer has a dense part with a higher density and a soft layer has a denser part than the dense part. A sparse part with a low density (for example, refer to Patent Document 1). [0003] However, in the above-mentioned multi-layer sound-absorbing material, since it is not easy to distinguish which side is a hard layer and which side is a soft layer, there is a problem that, for example, when the multi-layer sound-absorbing material is attached to a device, the Wrong installation direction. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2010-85873 Contents of the invention [0005] An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as t...
