Abstract
The present disclosure provides a key measuring device for measuring the touchweight parameters of one or more keys of a keyboard instrument, such as a piano. The key measuring device may include a plunger configured to contact a top surface of a key and move in a direction substantially perpendicular to said top surface and a force sensor coupled to the plunger and configured to provide an output signal indicative of the force between the plunger and the top surface of the key. Also provided are systems and methods for measuring touchweight parameters of a key.
Claims20
A key measuring device, comprising:
- a) a plunger configured to contact a top surface of a key and move in a direction substantially perpendicular to said top surface;
- b) a motor coupled to the plunger and configured to move the plunger in a controlled manner;
- c) a force sensor coupled to the plunger and configured to provide an output signal indicative of the force between the plunger and the top surface of the key;
- and
- d) a processing module configured to control the motor and receive the output signal from the force sensor.
A method of measuring one or more touchweight parameters of a key, comprising:
- a) providing a plunger configured to contact a top surface of the key and move in a direction substantially perpendicular to said top surface;
- b) providing a force sensor coupled to the plunger and configured to provide an output signal indicative of the force between the plunger and the top surface of the key;
- c) moving the plunger downward at a substantially constant rate to depress the key from a neutral position to a depressed position;
- e) receiving the output signal of the force sensor at a key position between the neutral position and the depressed position while the plunger is moving downward;
- and
- f) determining the one or more touchweight parameters based on the output signal received in step (e).
