Abstract

The device has a sound-absorbing element (1) suspended inside a percussion instrument, where the element is made of a foam, canvas and a spongy material. The element is suspended inside a barrel (3) by elastic or non-elastic connections i.e. rigid arms (2a). A fastener is carried out on an interior of the barrel with a hook and with magnets (4a) that are magnetized on internal metallic parts (5). The fastener is carried out below a skin using stickers, and is pinched between the skin and the barrel. The connections are fixed on the metallic parts.

Description

La présente invention concerne un dispositif d'atténuation des harmoniques produites par les instruments à percussion. Les instruments à percussion peuvent générer des sons harmoniques désagréables qui nuisent parfois à la qualité du son. The present invention relates to a harmonic attenuation device produced by percussion instruments. Percussion instruments can generate unpleasant harmonic sounds that sometimes interfere with sound quality.

Le dispositif selon l'invention permet de remédier à ce problème. Il comporte au moins un élément acoustiquement absorbant (1) suspendu à l'intérieur de l'instrument. Disposé ainsi, le dit élément (1) va atténuer les harmoniques produites lorsque l'instrument est joué. Selon les modes particuliers de réalisation : - Le ou les éléments acoustiquement absorbants (1) peuvent être en mousse, en matière spongieuse ou en toile. - Le ou les éléments acoustiquement absorbants (1) peuvent être suspendus à l'intérieur du fût (3) par un ou plusieurs liens (élastiques ou non) (2a), par un ou plusieurs bras rigides (2a) ou encore par un ou plusieurs bras unitaires avec le ou les éléments (2b). - La fixation peut se faire sur l'intérieur du fût (3), ceci avec des aimants (4a) qui s'aimantent sur des parties métalliques internes (5) ou par d'autres moyens connus de l'homme du métier (par exemple, avec un crochet : 4b). - La fixation peut aussi se faire sous la peau (6), ceci avec les moyens connus de 20 l'homme du métier (par exemple, avec un autocollant : 4c). - Selon une variante non illustrée, la fixation peut se pincer entre le fût et la peau. Les dessins annexés illustrent l'invention : La figure 1 représente une vue du dispositif de l'invention. Cet exemple est appliqué à une conga, l'élément (1) est suspendu par des bras ou des liens (2a) qui se fixent sur des 25 parties métalliques (5) à l'intérieur du fût (3) grâce à des aimants (4a). La figure 2 représente en coupe 2 différents modes de fixation sur l'intérieur du fût (3) : avec des aimants (4a) ou avec des crochets (4b). La figure 3 représente en coupe le dispositif de l'invention. Sur cet exemple, l'élément (1) est suspendu par des bras unitaires avec celui-ci (2b) fixés sous la peau (6) avec des 30 autocollants (4c). En référence à ces dessins, le dispositif comporte au moins 1 élément acoustiquement absorbant (1) suspendu à l'intérieur du fût (3). Disposé ainsi, le dit élément atténue les harmoniques produites lorsque l'instrument est joué. Dans la forme de réalisation selon les figures 1 et 2, le ou les éléments sont 35 suspendus par un ou plusieurs liens (élastiques ou non) (2a) ou par des bras rigides qui transpercent l'élément (2a). La fixation se fait sur l'intérieur du fût (3) à l'aide d'aimants (4a) qui s'aimantent sur les parties métalliques internes (5) afin de pouvoir installer et enlever le dispositif facilement, ou bien à l'aide de crochets (4b). Dans la forme de réalisation selon la figure 3, le ou les éléments (1) sont suspendus par un ou plusieurs bras unitaires avec le ou les dits éléments (2b), ceci dans le cas ou l'ensemble bras 1 élément(s) est réalisé en une seule pièce. La fixation se fait sous la peau (6), à l'aide d'autocollants (4c) afin de pouvoir installer facilement le dispositif, et ce, sans perçage. Selon une variante non illustrée, la fixation peut se pincer entre le fût et la peau. Le dispositif selon l'invention est particulièrement destiné à équiper les instruments 10 à percussions membranophones comme les congas, bongoes, djembés, timbales, caisses claires, grosses caisses, toms, etc.... The device according to the invention overcomes this problem. It comprises at least one acoustically absorbing element (1) suspended inside the instrument. Arranged thus, said element (1) will attenuate the harmonics produced when the instrument is played. According to particular embodiments: - The acoustically absorbent element (s) (1) can be foam, spongy material or canvas. - The acoustically absorbing element or elements (1) can be suspended inside the barrel (3) by one or more links (elastic or not) (2a), by one or more rigid arms (2a) or by one or more several unitary arms with the element or elements (2b). - Fixing can be done on the inside of the barrel (3), this with magnets (4a) which are magnetized on internal metal parts (5) or by other means known to those skilled in the art (by example, with a hook: 4b). Fixation can also be done under the skin (6), this with the means known to those skilled in the art (for example, with a sticker: 4c). - According to a variant not shown, the attachment can be pinched between the shaft and the skin. The accompanying drawings illustrate the invention: FIG. 1 represents a view of the device of the invention. This example is applied to a conga, the element (1) is suspended by arms or links (2a) which are fixed on metal parts (5) inside the barrel (3) by means of magnets ( 4a). Figure 2 shows in section 2 different modes of attachment on the inside of the barrel (3): with magnets (4a) or with hooks (4b). Figure 3 shows in section the device of the invention. In this example, the element (1) is suspended by unitary arms with it (2b) fixed under the skin (6) with stickers (4c). With reference to these drawings, the device comprises at least one acoustically absorbing element (1) suspended inside the barrel (3). Arranged thus, said element attenuates the harmonics produced when the instrument is played. In the embodiment according to Figures 1 and 2, the element or elements are suspended by one or more links (elastic or not) (2a) or by rigid arms which pierce the element (2a). The fixing is done on the inside of the barrel (3) by means of magnets (4a) which are magnetized on the internal metal parts (5) in order to be able to install and remove the device easily, or to the using hooks (4b). In the embodiment according to FIG. 3, the element or elements (1) are suspended by one or more unitary arms with the one or more said elements (2b), this in the case where the arm assembly 1 element (s) is made in one piece. Fixing is done under the skin (6), using stickers (4c) in order to easily install the device, and without drilling. According to a variant not shown, the attachment can be pinched between the shaft and the skin. The device according to the invention is particularly intended to equip instruments 10 with membranophone percussions such as congas, bongoes, djembes, timpani, snare drums, bass drums, toms, etc.
