Embodiment approach 1

[0050] figure 1 (A) is a perspective view schematically showing an example of the soundproof structure according to Embodiment 1 of the present invention, figure 1 (B) is figure 1 (A) Schematic cross-sectional view of the soundproof structure shown.

[0051] figure 1 (A) and figure 1 The soundproof structure 10 of this embodiment shown in (B) has a structure in which the soundproof unit 18 is arranged two-dimensionally. The soundproof unit 18 includes: a frame 14 having a hole 12; and a film 16 covering the hole 12. It is fixed on the frame 14 and can vibrate.

[0052] In this soundproof structure 10, the frame 14 and the film 16 are made of the same material and integrally formed.

[0053] The soundproof structure 10 of the illustrated example is composed of a plurality of 12 soundproof units 18, but the present invention is not limited thereto, and may also be composed of 1 frame 14, 1 film 16, and 1 or more through holes. A soundproof unit 18 constitutes.

Embodiment approach 2

[0107] Figure 4 It is a partial cross-sectional view schematically showing an example of a soundproof structure according to Embodiment 2 of the present invention.

[0108] Figure 4 The shown soundproof structure 10a of this embodiment has a structure in which the film 16 is arranged in the middle of the frame 22, and the film 16 is further arranged between the frame 14a on the upper side in the figure of the frame 22 and the frame 14b on the lower side in the figure. 16 has a hole 12a and a hole 12b on both sides. Therefore, the soundproof unit 18a is composed of a frame 22 including a frame 14a having the hole 12a and a frame 14b having the hole 12b, and the film 16 arranged between the hole 12a and the hole 12b.

[0109] here, Figure 4 In the soundproof structure 10a of the present embodiment shown, the film 16 is arranged between the frame 14a and the frame 14b of the frame 22, that is, between the holes 12a and the holes 12b. However, the film 16 and the frame have Th...

Embodiment approach 3

[0114] Figure 5 (A) is a perspective view schematically showing an example of a soundproof structure according to Embodiment 3 of the present invention, Figure 5 (B) is Figure 5 (A) A schematic partial cross-sectional view of the soundproof structure shown.

[0115] The soundproof structure 10b of this embodiment shown in these figures has a structure in which the soundproof unit 18b is arranged two-dimensionally. The soundproof unit 18b includes: a frame 14 having a hole 12; a film 16 fixed to the frame 14; and a spindle 24. , adhesively fixed to the membrane 16 .

[0116] In addition to the fact that the spindle 24 is bonded to the film 16, Figure 5 (A) and Figure 5 The soundproof structure 10b shown in (B) and figure 1 (A) and figure 1 Since the soundproof structure 10 of Embodiment 1 shown in (B) has the same structure, description about the same structure is abbreviate|omitted.

[0117] In the soundproof structure 10b of this embodiment, the spindle 24 is bond...

Abstract

Provided are a soundproof structure and a method for manufacturing the same. The soundproof structure has one or more soundproof cells, the one or more soundproof cells each being provided with a frame having a hole, a vibratable membrane fixed to the frame so as to cover the hole, and one or more through-holes passing through the membrane, wherein both end portions of the hole in the frame are not closed and the frame and the membrane comprise the same material and are formed integrally. Thus, stable soundproofing performance with improved resistance to environmental change and the passage of time can be achieved, and the problem in manufacturing of evenly attaching or sticking the membrane to the frame can be avoided.

Description

technical field [0001] The present invention relates to a sound-proof structure and a method for manufacturing the sound-proof structure. Specifically, it relates to a sound-proof unit comprising one or a plurality of two-dimensionally arranged frames integrally formed with a film fixed on the frame and used for selective A sound-proof structure that strongly shields sound of a target frequency, and a method of manufacturing the sound-proof structure for manufacturing such a sound-proof structure. Background technique [0002] For common sound-insulating materials, the heavier the mass, the better the sound-shielding effect. Therefore, in order to obtain a good sound-insulating effect, the sound-insulating material itself becomes large and heavy. On the other hand, it is especially difficult to block out sounds of low-frequency components. Generally, this region is known as the mass law, and when the frequency is doubled, the shielding improves by 6dB. [0003] As such, in...
