Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a novel muffling case that attenuates the sound of wind instruments.

(Prior art) For this purpose, conventionally a mute
was used, but because it was attached to the sound aperture, there was a problem in that the pressure loss was significant and it was difficult to produce sound, and it also had the disadvantage that the tone color changed considerably.

(Technical Issues) Therefore, the present invention was developed to create a wind instrument that can be played in the same way as usual without making any changes to the instrument itself, the tone does not change, only the volume can be reduced, and that can also be used as a bag. This provides a sound deadening case.

(Technical Means) The present invention which achieves the above object includes a case body 1 which accommodates wind instruments T and has a space where keys can be operated, an entrance 2 for wind instruments T, hand insertion openings 3 and 4, and A protruding opening 5 of the mouthpiece T' is provided, and the entrance/exit 2 can be opened and closed by a fastener 6, and furthermore, a bore, urethane, or other soundproofing/absorbing material 7 is pasted on the inner surface of the main body 1.

(Embodiment) The illustrated embodiment is a sound deadening case for an alto saxophone, and is made by sewing a side member 8 and a circumferential member 9, each having a side shape capable of accommodating a wind instrument T, and the outer cover is relatively lightweight. It is formed from woven fabric, sheet, etc. The inside of the case body 1 has a soundproofing/sound absorbing material 7 pasted thereon, and still has a space in which the wind instruments T can be accommodated and performance operations can be performed. Although it can be used, the fabric material of the example has long hair 10
A sponge 11 is stuffed between the outer cover and the outer cover. The case body 1 has an entrance/exit 2 along the longitudinal direction on one side,
While it can be opened and closed by a sliding fastener 6 provided on the rim of the opening, a mouth 5 is opened at its tip (the upper end of the wind instrument T) to project the mouthpiece T' out of the case, and the projection opening 5 can be covered. The tongue-shaped piece 12 is attached so as to be openable and closable with a hook 13, and the hand insertion openings 3 and 4 are formed wide to match the arrangement of the hands operating keys on both the left and right sides of the entrance/exit 2. 4, a tongue-like piece 12 is attached with a hook 13 so that it can be opened and closed, and is closed when not in use. In the embodiment, a carrying handle 14 and a hanging belt 15 are attached to both sides of the entrance 2 so that the carrying case can be carried by hand or hung on the shoulder, so that it can also be used as a carrying case for wind instruments T or other items. 16 is a hanging belt 15
17 is a pocket provided on the side surface of the case body 1, and 18 is a fastener for opening and closing the pocket.
Incidentally, the case body 1 can be formed into an external shape that matches the shape of a wind instrument as described above, or may be formed into a normal square external shape, and the thickness of the soundproofing/sound absorbing material 7 pasted inside can be changed in each part.

(Operation and effect of the invention) In the above, the wind instrument T is placed in the case body 1 with the mouthpiece T' removed, the fastener 6 is closed, the mouthpiece T' is attached, and the insertion ports 3 and 4 are closed. The player can open his hand, insert his hand, support the wind instrument T, and play as usual, and the sound is absorbed by the case body 1, especially the soundproofing and sound-absorbing material 7, and is attenuated.

Therefore, according to the present invention, the wind instruments T are simply housed within the case body 1 and no changes are made to the instruments themselves, so there is no change in the important tone, and the player can play with exactly the same feeling as usual. The case body 1 has a bore, urethane, and other soundproofing/sound absorbing materials 7, so it can also be used as a bag to reduce noise. It is light and easy to handle.
