Description

Dampers for wind instruments, for example for trumpets, are known in various designs. They are used to change the tone color or tone quality or the volume of the instrument. In the case of sheet metal wind instruments, the damper is often a hollow body, for example made of wood, metal, compacted cardboard or plastic, which is inserted into the sonic funnel and at which the end projecting into the tube is open. Such dampers are known from U.S. Pat. No. 1,546,258 A, EP 0 029 870 B1, GB 2 615 760 A or DE 923 767 B.Training dampers serve primarily as sound absorbers, i.e. are intended to reduce the volume without the intonation being changed too much.The technical problem underlying the present invention is the provision of a damper, in particular a training damper, which reduces the volume as much as possible when playing a wind instrument, in particular a sheet-metal wind instrument such as a trompet, without the necessity of corruptions of the intonation, that is to say individual tones do not become higher or lower as a result of the use of the damper and the feeling of play likewise remains substantially unchanged.The technical problem underlying the present invention is solved by a damper according to claim 1.The technical problem underlying the present invention is solved in particular by a damper for a wind instrument, having a damper base body with a first end, which can be inserted into the horn of a wind instrument and a second end, wherein the second end is closed by a concavely curved surface and a tubular sound outlet element extends through the concavely curved surface, characterized in that the tubular sound outlet element extends with a first portion into the damper base body and projects with a second portion from the concavely curved surface, wherein the damper base body can be dismantled into a first sub-element and a second sub-element, wherein the damper base body is provided in the region of the first end on the outer side with a sealing material, in the form of a wide ring or a sleeve, made of rubber, and wherein the damper consists of three parts, namely the first partial element of the damper base body, the second partial element of the damper base body with an integrated tubular clay outlet element and the sealing material.The wind instrument is preferably a sheet metal wind instrument, in particular a troubet. A damper for trumpets is therefore particularly preferred.The damper base body is preferably hollow on the inside. The damper base body preferably has a round cross section.Preferably, the damper is a training damper.It has surprisingly been found that a damper according to the invention generates a very strong sound reduction, in particular due to the concavely curved surface and the tubular sound outlet element, without changes in the intonation occurring. A reduction in the volume by 25 dB could be achieved by the damper according to the invention in the case of a troubet, so that the damper is surprisingly well suited as an exercise damper. It can be advantageously played with a sound attenuated in such a way that a troubter can practice in the same room without disturbing other people. In the embodiment as a training attenuator, the attenuator reduces the volume sufficiently, but the sound is still audible in space, so that no electronic microphone technique or the like needs to be used. At the same time, the feel of the game advantageously remains substantially unchangedAccording to the invention, the tubular clay outlet element extends with a first section into the damper base body and with a second section out of the concavely curved surface. Preferably, the first section and the second section are approximately of the same length.Preferably, the second section of the tubular sound outlet element does not protrude beyond the outer end of the second end of the damper base body. The sound outlet element can be in particular a tube which protrudes from the concavely curved surface from both sides, that is to say extends through the concave surface.Preferably, the tubular clay outlet element is positioned approximately at the center of the concavely curved surface.According to the invention, the damper base body can be divided into at least two partial elements. The two partial elements are preferably assembled approximately in the middle of the damper, for example pushed together or screwed or clicked, so that the damper can be reversibly disassembled into two approximately halves. Thus, the user has the possibility of cleaning the damper advantageously on the inside and thereby easily comes to all the inner surfaces of the damper. Preferably, the two sub-elements are joined together reversibly by a click system. The two sub-elements can also be irreversibly bonded together.The damper base body is preferably made of a plastic or of a WPC (wood-plastic composite), i.e. a wood-plastic composite material. It has been shown that the intonation is particularly well maintained in a damper base body made of plastic or made of WPC with the form according to the invention. Preferably, the damper base body and the tubular clay outlet element are manufactured from the same material. Depending on the field of application, the damper can also be made of another material, for example, of metal or an alloy, in particular of sheet metal. The skilled person is familiar with suitable materials for dampers.Particularly preferably, the damper base body is made of a plastic. Particularly preferably, the damper base body is made of WPC.The plastic can be, for example, polypropylene (PP), polyvinyl chloride (PVC) or polyethylene (PE).Typically, WPCs consist of a wood fibre or flour fraction of 50% to 90% and a plastic matrix of polypropylene (PP), of polyvinyl chloride (PVC) or of polyethylene (PE). Mixtures with other plastics and bio-based plastics are technically possible. The addition of additives optimizes specific material properties such as bonding between wood and plastic and flowability. Bamboo plastic composites (BPC) are composite materials in which wood fibers are replaced by bamboo fibers. These too can be used for the damper.The damper can be produced in an advantageous manner in a conventional manner, for example by injection molding, rotomolding, by means of pressing techniques or thermoforming methods, but also by 3D printing.In a particular embodiment, the damper, in particular if it is made of plastic or WPC and is produced in 3D pressure, can be double-walled. By virtue of the damper base body being double-walled, the sound insulation can be increased even more.Preferably, the damper base body and the tubular clay outlet element are manufactured from the same material. The tubular sound outlet element is thus preferably a component of the damper base body or of the second sub-element of the damper base body. This allows cost-effective and simple production.According to the invention, the damper base body is provided with a sealing material on the outer side in the region of the first end. According to the invention, the sealing material can bear in the form of a wide ring or a sleeve against the outer surface of the damper base body. The sealing material can be, for example, rubber or cork, according to the invention rubber. Preferably, the sealing material is shaped so that, when the damper is used, it completely seals the boundary surface between damper and instrument.According to the invention, the damper consists of three parts, namely first sub-element of the damper base body, second sub-element of the damper base body with integrated tubular clay outlet element and sealing material.In a preferred embodiment, the damper base body is tapered towards the first end.
