Multi-axis foot pedal for electric musical instruments

Control device for controlling a sound of an electric musical instrument, the control device comprising:

• a tread plate which is arranged to be rotatable about a first axis and is arranged to be rotatable about a second axis;
• and
• a signal generator which is configured such that it generates a first electric signal to control the sound and a second electric signal to control the sound, wherein the first electric signal is based on a rotation of the tread plate about the first axis and the second electric signal is based on a rotation of the tread plate about the second axis;
• a support surface;
• and
• a bearing which connects the tread plate to the support surface so that the tread plate is rotatable about the first axis and about the second axis, wherein the first axis and the second axis each extend parallel to the tread plate, wherein the first axis and the second axis are arranged perpendicular to one another,
• wherein the bearing comprises a first articulation and a second articulation, wherein the first articulation is configured such that the tread plate is arranged to be rotatable about the first axis, and wherein the second articulation is configured such that the tread plate is arranged to be rotatable about the second axis;
• wherein the signal generator comprises a first signal generating element, which is configured such that it generates the first signal based on a rotation of the tread plate about the first axis,
• wherein the signal generator comprises a second signal generating element, which is configured such that it generates the second signal based on a rotation of the tread plate about the second axis,
• wherein the first signal generating element is a first potentiometer and/or the second signal generating element is a second potentiometer,
• wherein the respective potentiometer is configured such that an electrical resistance therein changes depending on an angle of rotation of the tread plate about the axis associated with the respective potentiometer, and that the signal, associated with the respective potentiometer, is based on the changed electrical resistance of the potentiometer,
• and, wherein:
• i) the control device further comprises a Bowden cable, with an associated cable and an associated deflection, associated with the respective potentiometer, wherein the respective potentiometer and the deflection are fixed to the support surface, and wherein the cable is fixed at its two ends to the tread plate and runs around the deflection and the respective potentiometer,
• and wherein the Bowden cable is configured such that the length of the cable between a fixing point of the cable to the tread plate and the respective potentiometer changes when the tread plate rotates about the axis associated with the respective potentiometer, and the Bowden cable thereby causes the respective potentiometer to change the electrical resistance depending on the length of the cable between the fixing point and the respective potentiometer;
• or
• ii) the control device further comprises a toothing, with an associated first toothing element and an associated second toothing element, associated with the respective potentiometer,
• wherein the first toothing element is fixed to the bearing and the second toothing element is fixed to the respective potentiometer,
• wherein the first toothing element is configured such that it rotates when the tread plate rotates about the axis associated with the respective potentiometer,
• and wherein the second toothing element is configured such that it rotates when the first toothing element rotates, and the second toothing element thereby causes the respective potentiometer to change the electrical resistance depending on the angle of rotation of the tread plate about the axis associated with the respective potentiometer.
