DETAILED DESCRIPTION OF THE DRAWINGS
(10) A classical violin 1 according to
(11) At the lower end block 18, the strings of the violin 1 are braced by means of a tailpiece end on the top of the violin 1. Therefore, the lower end block 18 is very stable and firmly incorporated into the body 2. The upper end block 16, which supports the neck 4 and the fingerboard, is also sturdy and firmly worked into the body 2. Nowadays, the upper end block 16 and the neck 4 are usually manufactured separately and glued together in order to fulfill the necessary wearing characteristics as well as sound and vibration characteristics.
(12) Side panels, known as ribs 26, are attached to the side of the body bottom 10 in the area of the circumferential bottom edge 12, and a body top is then attached to these ribs 26 opposite the body bottom. These parts essentially form the body 2, which is the resonance chamber of the violin 1, and are stabilized with the help of the so-called outer blocks and the upper and lower end blocks 16, 18.
(13) In order to enable the musician to maintain a comfortable posture while playing the violin 1 while maintaining a high sound quality, a shoulder rest 30 is provided, as shown in
(14) The shoulder rest 30 is designed for a particularly high tonal quality of the ensemble of violin 1 and shoulder rest 30. Particular account is taken of the realization that the shoulder rest 30, which is attached to the body 2 and mechanically connected to it at the holding points, could have an influence on the vibration spectrum of the body 2 as a whole and in particular on its nodal points and impair the “free” unfolding of the sound spectrum. In order to limit or, if possible, completely avoid these inherently undesirable effects, the shoulder rest 30 is designed to limit jointly vibrating masses. This is achieved by segmenting the planar extended base body 34 of the support element 32 in such a way that it forms a plurality of separately vibrating elements. This segmentation could be achieved in various ways; in the embodiment shown considered to be particularly preferred, the support element 32 of the shoulder rest 30 is provided for this purpose with a number of opening slots 38 extending in the longitudinal direction L and completely penetrating the support element 32 in its thickness.
(15) The opening slots 38 are suitably selected with regard to the intended improvement of the tonal properties of the violin 1 and are adapted thereto. In the embodiment shown, they are designed to be comparatively long, and they have a length of about 70% of the length of the support element 32. Depending on the particular circumstances and requirements, they can alternatively also be comparatively short to comparatively long, in particular between 10% and 80% of the length of the support element in its longitudinal direction, comparatively wide to comparatively narrow, in particular with a width between 0.5 and 3 mm, and provided and dimensioned in a suitable number, in particular between 1 and 5.
(16) The opening slots 38 can penetrate the base body 34 of the support element 32 substantially perpendicularly. i.e., with their side walls 40 aligned parallel to the surface normal of the support element 32. In an alternative, preferred embodiment, as can be seen from the sectional representation in
(17) An alternative, particularly preferred embodiment of a shoulder rest 40 is shown in
(18) The holes 48 are arranged in respective hole tracks 50 extending in the longitudinal direction L of the support element 32, as is clear in particular from the plan view shown in
(19) In the variant shown in
(20) The holes 48 also form a hole pattern which is regarded as particularly favorable, in which a specifically combined ensemble of primary holes 52 on the one hand and secondary holes 54 on the other hand is provided. In this case, a hole track 50 formed by a number of primary holes 52 is arranged centrally in the support element 32 with respect to the width thereof, and at least one hole track 50 formed by a number of secondary holes 54 is arranged eccentrically in the support element 32 with respect to the width thereof, the secondary holes 54 each being arranged approximately in the middle between two adjacent primary holes 52, as viewed in the longitudinal direction of the support element 32. This arrangement of the holes 48 in their entirety makes it possible to achieve a particularly favorable transmission of the sound within the base body 34.
(21) In this connection, a total of five primary holes 52, relative to the width of the support element 32, are arranged centrally in the latter and the secondary holes 54, likewise relative to the width of the support element 32, are arranged off-center in pairs symmetrically relative to the center of the support element 32 in the latter and, viewed in the longitudinal direction thereof, in each case approximately in the center between two adjacent primary holes 52. This positioning of the holes 48 makes it possible in particular to take account of a plurality of actually divergent design objectives: on the one hand, particularly favorable guidance of the sound in the support element 32 is made possible, while on the other hand the structural integrity of the support element 32 itself can be kept particularly stable with respect to the weakenings caused by the holes 48.
(22) The primary holes 52 are selected to be equal in size to each other, as are the secondary holes 54 to each other. In addition, the individual hole area of the primary holes 52 is approximately four times the individual hole area of the secondary holes 54, i.e., the hole size, for example defined by the clear width of a hole 48, of the primary holes 52 is approximately twice the hole size of the secondary holes 54. This choice of geometry ensures that, viewed over the width of the support element 32, the cross-sectional proportion filled by the wood material in the region of the primary holes 52 is approximately as large as in the region of the secondary holes 54, so that, viewed in the longitudinal direction of the support element 32, particularly high-quality sound conduction properties result. In the embodiment example, the holes 48 occupy a total area of about 12.5% of the area of the support element 32. In general, it has been found that comparatively smaller holes 48 tend to produce a more muffled sound, whereas comparatively larger holes 48 tend to produce a more open sound, so that the selected hole size and thus also its area proportion of the total area of the support element 32 can also be suitably selected with respect to the desired sound behavior and, if necessary, also with respect to the material (wood) intended for use.
(23) In addition, the holes 48 are designed with sharp edges, since, compared to holes with rounded edges, a particularly pleasing sound pattern can be achieved thereby.
(24) Moreover, as can be seen particularly clearly from the plan view in
(25) The support element 32 can be provided on its rear side, i.e., on its side intended for resting on the player's shoulder, with a buffer element of comparatively elastic or soft material, for example a rubber buffer or the like. This buffer element may thereby also have holes which preferably correspond to the holes 48 and are arranged in position and dimension to match the latter. This provides completely continuous holes for the composite body consisting of the support element and the buffer element, which also ensure a special tonal quality of the composite body.
(26) As can also be seen from the plan view in
