Abstract

The present invention relates to a device for changing the sound of a musical instrument, comprising at least one element that produces a sound in the event of vibration, said element being attached to a retainer (10), and fastening means on the retainer in order to detachably attach said retainer to the musical instrument. According to the invention, at least one magnet element (12) is provided on the retainer, which magnet element, in conjunction with a metal or magnetic counter element on the musical instrument, makes it possible to fasten the device to the musical instrument. Because of the easily detachable fastening of the device to the musical instrument, a temporary change in the sound can be achieved, because the element (11) that produces sound resonates when a surface, for example of a drum or of a cajón , to which the device is fastened by means of a magnet is struck. Because the device can be easily removed from the musical instrument again at any time, no structural change to the instrument itself results. Nevertheless, the fastening of the device by means of a magnet is sufficiently strong and secure so that the device cannot detach unintentionally.

Description

Device for changing the sound of a musical instrument

The present invention relates to an apparatus for changing the sound of a musical instrument, comprising at least one vibration generating sound generating member attached to a holder and fixing means to the holder for releasably attaching the holder to the musical instrument.

A device for changing the sound of a percussion instrument such as a cajon has become known from the prior art and is for example from the company Pearl on their website

www.pearleurope.com/ProductDetails. aspx? Productld = 595 & ColorlD = 0 & Action = Link offered. The device is also referred to by Pearl as "jingle cups" and comprises two or more small plates (also platinellas) made of metal, for example brass or the like, which are mounted on a holder so as to be movable relative to one another by means of a screw Holder is as a fastener a kind of suction cup, by means of which one can attach the (relatively small) device to the surface of the percussion instrument, thereby causing the small platelets to vibrate and thus to produce an additional sound, for example similar to a tambourine For example, if such a device is attached to the surface of a cajon, a shock to the cajon, which is applied by hand, will also cause the slides of the device to beat against each other by the shock, creating a ringing sound (jingle) It is also known the screw that is itself axially displaced through the center of the platelets, so as to vary the distance of the platelets relative to one another, whereby a change in the sound intensity can be brought about, since the range of motion of the platelets and thus the amplitude of the oscillation changes.

A disadvantage of a device of the aforementioned type that the attachment to the drum surface by means of suction cup is not sufficiently resistant. Due to the shocks on the drum surface resulting vibrations, the Saugnapfverbindung can solve and the device falls to the ground. The surfaces to which the suction cup is attached are usually made of wood and very smooth and experience has shown that a secure attachment of the device for a sufficient period of time when using the drum, which is exposed to constant vibration, is not given ,

The object of the present invention is to improve a device for changing the sound of a musical instrument with the features of the type mentioned in that it can be safer and permanently (but still solvable if necessary) attached to the musical instrument. Furthermore, it is an object of the invention to provide further attachment options for the device on the musical instrument, so that attachment is possible not only on a wooden striking surface such as on a cajon.

The solution to this problem provides a device for changing the sound of a musical instrument of the aforementioned type with the features of claim 1.

According to the invention it is provided that at least one magnetic element is provided on the holder, which allows in connection with a metallic or magnetic counter-element on the musical instrument attachment of the device to the musical instrument.

The solution according to the invention on the one hand ensures a secure and permanent attachment of the device to the musical instrument. Magnets of a sufficient size are available which are so strong that, even with the vibrations occurring as a result of playing the instrument, it is impossible for the device to drop off the musical instrument by itself. Furthermore, the solution according to the invention also provides new possibilities of attachment, i. the device is more versatile in its field of application than known solutions. For example, you can attach the counter element in a variety of areas on a musical instrument, a percussion instrument, for example, on the frame, the striking surface, etc. The invention is not limited to percussion instruments, but can also be used in stringed instruments such as guitars or others to to vary the sound, making the instrument more interesting to the user.

Preferably, according to an embodiment of the invention, it is provided that the magnetic or metallic counter element in the region of an abutment surface of a knob or The like is arranged, which is attachable when not in use on the magnetic element of the holder. In this variant, it is thus not necessary that the user has a separate counter element, but this is present on the device. He can solve the counter element of the device and then attach at a suitable location on the musical instrument to attach the device there. When not in use, it can adhere the counter element again to the magnet of the holder so that it is captively mounted there.

For example, this variant of the invention also provides the possibility of not attaching the device to a supporting component of the musical instrument, such as e.g. on the frame, on the striking surface etc., but for example on a sound skin. This works so that one touches a surface of the holder on the sound of the musical instrument and then the previously removed from the holder counter element on the magnetic element opposite side of the sound head in height of the magnetic element on the sound filing touches such that a frictional connection between Magnetic element and counter element is made at lying between these sound head. This causes the jingles of the device to resonate due to the vibrations of the soundfelt, which is also interesting because the device can be attached to different parts of the soundfoil, for example farther in the middle or farther at the edge and so on In the case of a suction cup as a fastening means, such a method of attachment would not be possible at all, since the suction cup has no hold on the sound skin the attachment of the device, the soundhead between the magnetic element and the counter element.

According to a preferred embodiment of the invention it is provided that the magnetic or metallic counter-element is attached to a surface of the musical instrument or is preferably detachably attachable to this. In this variant of the invention, it is possible, for example, at any point of the musical instrument to attach a fastening element such as a double-sided adhesive tape on which the magnetic element is attached so that it can be loosened again if necessary and elsewhere the music element can be attached. It is advantageous that a double-sided adhesive tape has good adhesion and that the point at which the counter element is located can still be selected variably. If necessary, the adhesive tape can be removed again from the musical instrument without residue. As a counter element, for example, serve a thin plate of metal, which applies only little and barely noticed. The attraction of the magnetic element on the device is sufficient but to ensure a sufficient adhesive force for the attachment of the device to the metallic plate. Of course, you can also attach alternatively to the holder of the device, a simple metal part and attach the magnetic element as a counter element to the musical instrument.

Preferably, according to a further development of the invention, a bore or threaded bore is provided on the holder so that the holder can be screwed to the musical instrument by means of a screw-like fastening element or by means of a screw and nut. Here is another alternative method of attachment. In this variant, for example, in order not to damage the musical instrument, create the holder of the device to a frame part of the musical instrument, put a screw through the hole of the holder and tighten by a nut from the other side, so that the holder on the Musical instrument is optionally clamped by means of an additional clamping plate, without it being necessary to drill into the instrument.

Alternatively, a resilient clamping device can be attached to the holder of the device, similar to the one used for example in the electrical field, so that the device can be detachably clamped to a musical instrument. This clamping device can also be removable from the holder, so that they are used only exceptionally, if a particularly strong attachment is desired or the other mounting options are not eligible.

Preferably, according to a development of the invention, at least one elastic ring is attached to the holder, by means of which an operator can detachably attach the device to a finger. This results in a further possibility of using the device according to the invention, since the player of a musical instrument can hold the device by the hand, without thereby significantly limiting his ability to move. Thus, for example, when playing a guitar or a percussion instrument, additional sounds can be generated by means of the device according to the invention. If the elastic ring temporarily not needed, because other fastening methods are used, it can be provided on the holder at least one groove in which one can set the elastic ring when not in use. In this case, the elastic ring is not available, is fixed and does not interfere with the bracket.

There are a variety of ways to design the device according to the invention. The following variant is therefore only by way of example and not restrictive understand. For example, the holder of the device according to a preferred embodiment of the task solution according to the invention seen in side view may be approximately angular, in particular approximately L-shaped with at least two legs, wherein in a first leg, the magnetic element is embedded. In a second leg of the holder can then be provided, for example, the bore or threaded hole for the screw-like fastener.

On one side of the first leg of such an angle-shaped holder, the sound-generating element can then be attached, for example on the side of this leg opposite the magnetic element. In this variant, a very compact design of the device results, which can thus be built relatively small, but nevertheless offers all the above functions and alternative mounting options on the musical instrument - namely attachment to the instrument, by magnet, on the frame or on a sound head of the instrument, Attachment by screwing, by clamping or attachment to the hand by means of an elastic ring.

The features mentioned in the dependent claims relate to preferred developments of the task solution according to the invention. Further advantages of the invention will become apparent from the following detailed description.

Hereinafter, the present invention will be described in more detail by way of embodiments with reference to the accompanying drawings.

Showing:

Figure 1 is an exploded perspective view of an exemplary device according to the invention;

Figure 2 is a view of the holder of Figure 1 viewed from below on the shorter leg;

Figure 3 is a corresponding side view of the holder of Figure 2;

FIG. 4 shows a view of the holder, seen on the longer limb, looking in the direction of the axis to which the sound platelets are fastened. The present invention will first be described in more detail below with reference to FIG. This shows a perspective view of an exemplary device according to the invention comprising a holder 10, are attached to the two, three or more discs 1 1 (so-called jingles) loosely so that they beat against each other in a vibration and thereby generate a sound (similar such as the sound tiles on the frame of a tambourine.) The attachment of the tiles 1 1 can for example be done by an axial fastener such as a pin, bolt or screw is used, which extends approximately centrally through each hole in the sound tiles, wherein In addition, an abutment element can be plugged onto the axial fastening element at the end, which prevents the sound platelets from sliding off the axial fastening element. However, the attachment of the sound tiles is such that they each have some play on the axial fastening element in the axial direction, so that they can easily move and beat against each other. The exact way of attaching the sound tiles is not critical and is therefore not shown in detail in the drawing. It can, in principle, be similar to other musical instruments that have such jingles. In the present invention, it depends primarily on the holder 10, in which the jingles are 1 1, this holder can be attached to a musical instrument in different ways.

The holder 10 has seen in the side view in principle an L-shape with a first longer leg 10 a and a second slightly shorter leg 10 b, which is approximately at right angles to the first leg 10 a and with the latter approximately in the lower end region connected is. At the first longer leg 10 a, the sound platelets 1 1 are attached to one side in the area above the second shorter leg 10 b. At the side of the first leg 10 a opposite the sound platelets 1 1, there is a magnet 12, which is largely formed in the material of the support, e.g. made of wood, is embedded, so that it does not or only slightly protrudes. Associated with this magnet 12 is a knob 13 or a similar detachable element, on which there is also either a magnetic element 14 or a metallic element, so that the knob with the surface of the magnetic element 14 can be placed on the magnet 12, so that the knob sticks there. This magnet 12 and the magnetic element 14 as a counterpart serve for a form of attachment of the device 10 to the musical instrument, as will be explained in more detail later.

At the bottom of the holder 10 in the region of the second leg 10 b is a groove 15 in which when not in use at its other end portion 16 a at the holding tion 10 festlegbarer elastic ring 16, which consists for example of rubber, can be recorded and fixed. In this fixed position shown in Figure 1, the elastic ring 16 is biased. This elastic ring can be solved by pulling out of the groove 15, but is still set at its end portion 16 a to the bracket 10 and you can then put the elastic ring 16 around a finger, so as to hold the device to the hand and when hitting a percussion instrument with your hand by the vibration of the jingles 1 1 to create an additional sound.

For a further alternative way of fastening the device to a musical instrument, a clamp 17 can be used, which is shown schematically in FIG. 1 and which, as one sees, can be attached to the holder 10 with its one end, for example in the region of the groove 15 that the other free end of the clamp 17 can be clamped to a musical instrument.

Figure 2 shows a view of the holder, in which one looks at the bottom of the shorter leg 10 b, in which case the elastic ring 16 is shown in the released state. In Figure 2, it can be seen further that at the bottom of this second leg 10 b is another preferably largely embedded magnetic element 18 which has a hole 19 which also extends through the leg 10 b of the holder therethrough. In this way, a further attachment for attachment of the device is provided on a musical instrument, which opens from Figure 2 in conjunction with Figure 3. As you can see, through the hole 19, a screw 20 are inserted through, on the thread then, for example, a nut 21 (eg wing nut) can be screwed so that you can clamp the device in this way to a musical instrument, advantageously without on the instrument itself to make a hole, but possibly also with such a hole.

In Figure 4 can be seen the elastic ring in the fixed state of the device in the groove 15, while the ring 16 is shown in Figure 2 in the released state. FIG. 4 also shows the magnet 12 which is let into place on the longer limb 10 a and serves to attach the knob 13 shown in FIG. 1 to the magnet element 14 when not in use on the device. If you want to use the magnetic element 14 for attaching the device to a musical instrument, then you take the knob 13 from the bracket 10 and sets him at any point with the surface of the magnetic element 14, for example, on a sound head of a percussion instrument. On the opposite side of the sound skin you can then place the corresponding surface of the magnet 12 on the holder, so that the two magnetic or metallic surfaces 14, 12 mutually attract, between them the soundhead is located and in this way the device can be mounted on the whole in a simple manner to the surface of a soundhead of a musical instrument, without the need for an intervention is necessary for a permanent change (eg bore or the like) on the musical instrument. A particular advantage is also that the point of attachment to the sound head is virtually arbitrary, which can also vary the generated sound, depending on whether, for example, the device radially further outward or further inside on a clamped outside in a frame soundhead install. It is also possible to use the magnet 12 on the first leg 10 a of the holder to mount the device virtually anywhere on a metallic component of a musical instrument. If no suitable components are present on the instrument, it is possible, for example, to use small metallic plates which are attached to the musical instrument by means of double-sided adhesive tape, for example, so that the device is placed on a striking surface of a percussion instrument or a resonating surface of a guitar, for example can be so that the sound tiles 1 1 when playing the instrument are vibrated and thus resonate.

Thus, the following types of attachment of the device to a musical instrument exist:

1 . via the magnet 12 and the magnetic element 14 as a counterpart to a soundhead

2. by clamping by means of the terminal 17 shown in FIG

3. by clamping by means of the screw 20 and nut 21 in Figure 3

4. by attaching by means of the magnet to a metallic counterpart on the instrument

In addition, the fifth type of use is attachment to the player's hand by means of the elastic ring 16.
