The noise reduction device includes a housing, a first connector to protrude from one end of the housing, connected to the air pump, and having an inner diameter smaller than that of the housing, a second connector to protrude from the other end of the housing, connected to the air bag, and having an inner diameter smaller than that of the housing, a sound absorbing material filled in a partial space inside the housing, and a vibration-proof material filled in the remaining space inside the housing where the sound absorbing material is not filled.

BACKGROUND

1. Technical Field

An embodiment of the present invention relates to a motion pillow.

2. Background Art

A motion pillow includes a pillow and a solution box. When the motion pillow detects snoring while a user sleeps on a pillow, the motion pillow injects air to an air bag (air bag provided at a head of the user among a plurality of air bags) embedded in a pillow through an air pump of a solution box to expand the pillow, thereby turning the head of the user.

A typical motion pillow is configured in such a manner that as an air hose connecting the air bag of the pillow and the solution box is connected through an upper center of the pillow, the air hose may pass through a separate through-hole formed in an upper center of a pillow cover. In this case, when a user replaces the pillow cover as necessary or according to a taste of the user, replacement of the pillow cover is extremely difficult.

Also, in case of the typical motion pillow, the user may not adjust a height of the pillow to a desired height of the user, and a noise (which is heard by the user when the user lies on the side, and an ear to the user touches the pillow) caused by a vibration of a pump when air is injected from the solution box to the air bag is generated.

The first vibration-proof material135and the second vibration-proof material137may serve to reduce a vibration caused by the air pump127when air passes through the housing131. For example, although each of the first vibration-proof material135and the second vibration-proof material137may include natural rubber, styrene-butadiene rubber, or butadiene rubber, the present invention is not limited thereto. For example, each of the first vibration-proof material135and the second vibration-proof material137may include various materials capable of reducing a vibration in addition thereto.

Each of the first vibration-proof material135and the second vibration-proof material137may have a thickness (i.e., a length in a longitudinal direction of the housing131) less than that of the sound absorbing material133. In an exemplary embodiment, although each of the first vibration-proof material135and the second vibration-proof material137may have a thickness that is 0.1 times to 0.3 times of a thickness of the sound absorbing material140, the present invention is not limited thereto.

FIG.8is a cross-sectional view illustrating the first vibration-proof material135in the noise reduction device according to an embodiment of the present invention. Here, the second vibration-proof material137may have a cross-sectional shape that is the same as or similar to that of the first vibration-proof material135. Referring toFIG.8, the first vibration-proof material135may include an outer structure135a, an inner structure135b, an outer piece135c, and an inner piece135d.

The second inner structures135b-2may be spaced by a predetermined gap from each other on an outer surface of the first inner structure135b-1to connect the first inner structure135b-1and the outer structure135a. Although the second inner structures135b-2are spaced by 90° on the outer surface of the first inner structure135b-1inFIG.8, the present invention is not limited thereto. For example, the second inner structures135b-2may be spaced by 60° or 120° as necessary. The second inner structures135b-2may serve to divide a space between the first inner structure135b-1and the outer structure135ainto a plurality of spaces.

The outer piece135cmay be filled in each of the spaces divided by the second inner structure135b-2in the outer structure135a. The outer piece135cmay be made of a material capable of reducing a vibration.

The inner piece135dmay be filled in the inner space of the first inner structure135b-1. The inner piece135dmay be made of a material capable of reducing a vibration. Although the inner piece135dmay be made of the same material as that of the outer piece135c, the present invention is not limited thereto. Here, the outer piece135cand the inner piece135dmay be isolated from each other by the first inner structure135b-1and the second inner structure135b-2.

A through-hole135c-1may be formed in the outer piece135cin a thickness direction of the outer piece135c. The through-hole135c-1may be formed in a central portion of the outer piece135c.

The through-hole135d-1may be provided along a thickness direction of the inner piece135d. Also, the through-hole135d-1may be provided at a central portion of the inner piece135d. Here, each of the through-holes135c-1and135d-1may have an inner diameter less than that of each of the first connector131aand the second connector131b.

As described above, as the sound absorbing material133through which air passes is embedded inside the housing131, and the first vibration-proof material135and the second vibration-proof material137each having the through-holes135c-1and135d-1are provided at both sides of the sound absorbing material133, air may easily pass from the air pump127to the air bag111, and also the noise and the vibration caused by the air pump127may be prevented.

FIGS.10and11are views showing a noise experiment result when the noise reduction device108is not provided when air is supplied from the air pump127to the air bag111. Referring toFIGS.10and11, when the noise reduction device108is not provided between the air pump127and the air bag111, a vibration is measured in a low-frequency band and a noise (55.8 dB) is measured in a high-frequency band. Here, the vibration in the low-frequency band is generated from the air pump127, and the noise in the high-frequency band is generated from a motor (not shown).

FIGS.12and13are views showing a noise experiment result when air is supplied from the air pump127to the air bag111through the noise reduction device108according to an embodiment of the present invention. Here, the noise reduction device108is measured in a state in which only the sound absorbing material133is filled in the housing131without the first vibration-proof material135and the second vibration-proof material137.

Referring toFIGS.12and13, it may be seen that a noise in a high-frequency band is 49.1 dB that is remarkably reduced from that ofFIGS.10and11. However, since the first vibration-proof material135and the second vibration-proof material137are not filled in the noise reduction device108, it may be seen that a small amount of vibrations in the low-frequency band is remained.

FIG.14is a view showing a noise experiment result when the sound absorbing material133is provided at an inner center of the housing131, the first vibration-proof material135and the second vibration-proof material137are provided at both sides of the sound absorbing material133, and the through-hole135c-1is formed in the outer piece135cinside the noise reduction device108as illustrated inFIG.8.

Referring toFIG.14, it may be seen that the noise in the high-frequency ban is further reduced to 29.9 dB, and the vibration in the low-frequency band is also reduced.

Also,FIG.15is a view showing a noise experiment result when the sound absorbing material133is provided at an inner center of the housing131, the first vibration-proof material135and the second vibration-proof material137are provided at the both sides of the sound absorbing material133, and the through-hole135d-1is formed in the inner piece135din the noise reduction device108as illustrated inFIG.9.

Referring toFIG.15, it may be seen that the noise in the high-frequency band is further reduced to 29.4 dB, and the vibration in the low-frequency band is also reduced.

FIG.16is a view illustrating a noise reduction device208according to another embodiment of the present invention. Here, a housing231of the noise reduction device208may include a first housing231-1and a second housing231-2. That is, the housing231may have a cross-section in a longitudinal direction thereof, and the first housing231-1and the second housing231-2may be distinguished based on the cross-section. Here, although the cross-section may be formed at a center based on the longitudinal direction of the housing231, the present invention is not limited thereto.

The first housing231-1and the second housing231-2may be bonded to each other at the cross-section. The first housing231-1and the second housing231-2may be bonded to each other, and then taping may be performed on an outer surface of the housing231.

Here, reason of distinguishing the housing231into the first housing231-1and the second housing231-2based on the cross-section is to easily insert the sound absorbing material233and the vibration-proof material233into the housing231. That is, as the housing231into the first housing231-1and the second housing231-2are distinguished, the sound absorbing material233and the vibration-proof material233may be embedded into the housing231with various shapes and arrangements.

FIG.17is a view illustrating a state in which the sound absorbing material233is filled inside the first housing231-1in the noise reduction device208according to another embodiment of the present invention, andFIG.18is a view illustrating a state in which the vibration-proof material235is filled inside the second housing231-2in the noise reduction device208according to another embodiment of the present invention. However, the present invention is not limited thereto. For example, the sound absorbing material233may be provided at an inner center of the housing231, and the vibration-proof material235may be provided at both sides of the sound absorbing material233. Also, the sound absorbing material233or the vibration-proof material235may be embedded in the entire inside of the housing231, or at least one of the sound absorbing material233and the vibration-proof material235may be filled into the housing231with various shapes and arrangements.

As described above, as the housing is distinguished into the first housing231-1and the second housing231-2based on the cross-section, at least one of the sound absorbing material233and the vibration-proof material235are filled therein, the first housing231-1and the second housing231-2are bonded to each other at the cross-section, and then taping is performed on the outer surface of the housing231, the sound absorbing material233and the vibration-proof material235may be easily filled into the housing231, and assembly convenience of the housing may be improved.

Although the noise reduction devices108and208are applied to the motion pillow in this specification, the present invention is not limited thereto. For example, the noise reduction devices108and208may be applied to various fields that require noise reduction.

Although the embodiments of the present invention have been described, it is understood that the present invention should not be limited to these embodiments but various changes and modifications can be made by one ordinary skilled in the art within the spirit and scope of the present invention as hereinafter claimed. Therefore, the scope of the present invention is defined not by the detailed description of the invention but by the appended claims, and all differences within the scope will be construed as being included in the present disclosure.
