摘要:
A tension adjustment hoop (1) for tensioning a resonant skin (13) on a musical instrument (6, 25), the tension adjustment hoop (1) being formed by a ring (2) with a centre axis (3) and with retention means (4) arranged to interact with coupling means (5) on the musical instrument (6, 25) for retention of the tension adjustment hoop (1), the tension adjustment hoop (1) having an opposing top side (7) and bottom side (8), where the tension adjustment hoop (1) comprises an inner fluid channel (17), provided with a pressure adjustment connection (26) in hydraulic connection with the fluid channel (17), and a plurality of pistons (10), each in hydraulic connection with the fluid channel (17), each with a free end (11) opposite the fluid channel (17), and each, under the influence of the pressure in the fluid channel (17), being displaceable in a direction parallel to the centre axis (3) of the tension adjustment hoop (1) between a first extreme position, where the free end (11) is within or level with the bottom side (8), and a second extreme position, where the free end (11) is outside the bottom side (8).
摘要:
Bei der Kesselpauke erfolgt das Verstellen der Tonhöhe durch Spannen des Trommelfells, dessen Rand mit einer vertikal verstellbaren Scheibe (5) verbunden ist. Es ist eine technische Lösung angegeben, mit welcher die Tonhöhe rasch und präzise sowie ohne Kraftaufwand verstellt werden kann. Dies geschieht dadurch, daß ein elektrischer Schrittmotor (7) mit der Scheibe gekuppelt ist.

Eine Anordnung zum Stimmen einer Pauke weist einen Krafthebel (9, 9') auf, welcher mit dem Paukenkessel (1) derart wirkverbunden ist, dass bei dessen Betätigung der Kessel (1) gegen das Fell (3) treibbar bzw. von diesem weg bewegbar ist. Für die Kraftübertragung ist mindestens eine Kraftübersetzung und/oder eine Kraftumlenkung zur Kraftverstärkung für das Bewegen des Paukenkessels vorgesehen.
摘要:
A percussion instrument includes a drum body (13) and a percussion head (19) movable with respect to and stretched over therdrum body (13). A master tensioning member (55) is provided for pulling the drumhead (19) downward to enable a musician to vary the pitch of the sound produced when the drumhead (10) is struck. The master tensioning member (55) is operatively coupled to the drumhead (19) and is adaptable for use with drumheads of varying size. A lever system (Fig 3) is provided for moving the master tensioning member vertically downwardly. A foot pedal (336) is provided for enabling the user to actuate the lever system. The pedal (336) includes an engaging tooth (182) and is swivel- able to engage and disengage the tooth with complementary teeth to lock the pedal (336) selectively in position. The pedal tooth thereby permits the user to adjust and fix the tension on the drumhead. The pedal is connected to the lever system by a movable fulcrum, (252, 258) which permits the user to exert a smooth, even force when depressing the pedal and actuating the lever system.
摘要:
The invention relates to a device for setting skin tension, in particular for use in a musical instrument such as a kettledrum. The device comprises a tensioning star provided with an engaging element for engaging an operating mechanism for adjusting the tensioning star in an axial adjusting direction, substantially parallel to a central axis of the tensioning star. The tensioning star is also provided with a plurality of arms extending substantially in radial directions of which at least a part is provided with a coupling element for coupling to a tensioning rod construction attachable to the skin. In addition, the device comprises an adjusting device for adjusting the distance between a coupling element and the central axis of the tensioning star.
