A dissipating medium made of a stone-like tile. The tile used for removing a wolf note and its related energy, when played on a string musical instrument. The tile is made of a natural mineral, such as travertine. Also, the tile has a shear wave velocity between 300 to 440 m / sec. The tile can have an angular or annular shape. The angular shape is in a range of 10 to 12 inches square and a thickness in a range of ½ to ¾ inch. A top surface of the tile includes an annular depression for receiving an end pin of a cello's tail piece. The medium can be constructed of two tiles with an upper tile 10 inches square and a lower tile 12 inches square. Also, the medium has a weight in a range of 6 to 12 pounds for ease in transporting.

An adjustable support 12 for a stringed musical instrument such as a cello 10 includes a shaft 14 that is removably inserted into the cello 10, and a support member 16 that is adjustably disposed upon and secured to the shaft 14. The support member 16 includes an insertion portion 26 with a stabilizing bushing 72 disposed thereupon for stabilized insertion into an aperture in a bottom portion 11 of the cello 10, an annular portion 28 with an annular wall 34 for engaging and supporting the bottom portion 11 of the cello 10, and a lower portion 30 for securing the support member 16 circumferentially about a cylindrical outer wall 18 of the shaft thereby allowing an artist playing the cello to select a comfortable elevated and stabilized position of the cello 10 above a floor surface.

An electric cello is equipped with a pickup unit under a bridge, and strings are stretched to press the bridge; the pickup unit has a bridge tray where the bridge stands and a piezoelectric transducer provided beneath the bridge tray, and the bridge tray is bolted at a side portion under the thick string to the instrument body; however, the other side portion under the thin string is made freely vibrate; while a player is bowing on the strings, the vibrating strings give rise to rolling of the bridge, and the leg portions of bridge are alternately pressed on the side portion and the other side portion; only the vibration of the other side portion give rise to deformation of piezoelectric converter so that the piezoelectric converter is free from interference of the bolted side portion.

A device for restraining or anchoring the endpin of a floor-resting musical instrument such as a cello or a string bass is provided for allowing the musician to hold the musical instrument in a desired position and prevent the endpin from sliding around on the floor surface. The device also protects the surface of the floor from being damaged by a sliding endpin. The device also does not dampen the sound of the musical instrument.

The violoncello comprises a case (1) and strings (2), wherein the middle portion of the front surface of the case (1) is provided with a bridge (3), the bridge (3) is provided with four string grooves (31), left and right sides of the bridge (3) are symmetrically provided with two sound holes (6), the lower end of the case (1) is provided with a tailpiece (4), four rows of string positions are arranged on the tailpiece (4) with equal intervals, the front face of each string position is provided with an adjusting nut (51), an opposite face of each tuning position is provided with an adjusting seat, an upper end of each adjusting seat respectively stretches out from the front surface of the tuning position at the corresponding position, the strings (2) penetrate through the string grooves (31) at the corresponding positions, and the strings (2) are fixedly connected with the adjusting seats at the corresponding positions. According to the violoncello, the string positions of the tailpiece are correspondingly provided with adjusting holes and adjusting grooves, length of the strings and tension force are adjusted, each tuning position is adjusted and stabilized to realize the required tone quality, and the violoncello has a simple structure, is convenient to operate and has a wide application scope.

The invention discloses a violoncello comprising a case (1) and strings (2). A bridge (3) is arranged at the middle part of the front surface of the case (1). The bridge (3) is provided with four string grooves (31). Two sound holes (6) are symmetrically arranged at the left and right sides of the bridge (3). A tailpiece (4) is arranged at the lower end of the case (1). Four rows of string positions are equidistantly arranged on the tailpiece (4). An adjusting nut (51) is arranged at the front surface of each sound tuning position in a penetration way. An adjusting base is arranged at the reverse surface of each sound tuning position. The strings (2) penetrate through the string grooves (31) of the corresponding positions and fixedly connected with the adjusting bases. A side pad adjusting device is arranged at the lower end of the case (1). The adjusting holes and the adjusting grooves are correspondingly arranged on the string positions of the tailpiece for adjusting the length and the tension of the strings, and the side pad adjusting device is also arranged to achieve the effect of adjusting and stabilizing the tone of each sound tuning position so that the violoncello is simple in structure, convenient to operate and wide in range of application.

The invention relates to a string length regulator. Twelve string fastening holes are arranged on a tailpiece and successively comprise four string fastening holes in a first row, four string fastening holes in a second row, three string fastening holes in a third row and one string fastening holes in a fourth row, and the four rows of string fastening holes are all aligned to the left; the left three string fastening holes in the first row are irregular string fastening holes with circular upper segments and rectangular lower ends, and the rightmost string fastening hole is a circular hole; the first string fastening hole on the left in the second row is an irregular string fastening hole with a circular upper segment and a rectangular lower end, and the right three string fastening holes are circular holes; and the string fastening holes in the third row and the string fastening hole in the fourth row are all circular holes. According to tuning needs, the string fastening holes at four different positions can be selected, and strings are fastened to the tailpiece through cooperation between the selected string fastening holes and tuning pegs. Through the string length regulator, the lengths of strings can be changed, the heights of the strings can also be adjusted, accordingly, the tone quality and the volume are adjusted, the structure is simple, the installation and replacement are easy, and the string length regulator is especially suitable for a violoncello.
