An automatic playing system may include a damper module for changing a sound generated by the automatic playing system. The damper module may include a damper board, a motion driver, and a supporter. The damper board may be configured to control at least one damper of the automatic playing system. The motion driver may be configured to drive the damper board and operated to perform at least one automatic playing function. The supporter may be configured to couple the damper board with the motion driver when the motion driver is operated.

The combination of a piano and an actuating device for a pedal on the piano. The actuating device has a frame, an arm on the frame movable in a controlled path, and an actuator assembly. The actuator assembly has a component moved from a first position into a second position to thereby cause the pedal to move from the starting position into the actuated position. The actuator assembly is configured so that movement of the arm in a first direction in the controlled path causes the one component to move from the first position into the second position. The arm is movable by a leg of a user situated in a playing position with respect to the piano.

A hybrid acoustic piano, specifically a piano the wires whereof are struck, of the type including a grouped wires, where of each group of three or of four wires associated with a key, one of these is tuned at a pitch different from the other two or three, which are tuned identically; and where the mechanism is such that when the pedal is in a resting state, that is, without depressing the pedal, on pressing the keys, the hammers strike at least two wires of the three or of the four wires of each group with the same tuning, and when the pedal is depressed, the mechanism displaces the hammers to the right and, on pressing the keys, three wires are struck, one of which is the wire tuned at a different pitch from the others.

A piano system with key assisted user input may include one or more execution devices, one or more sensors, at least one signal processing circuit, a processor and a display. The one or more sensors may be configured to detect a signal indicating a status change of at least one of the one or more execution devices. The at least one signal processing circuit may be configured to generate a control signal for controlling an input of a computer device in response to the signal detected by the one or more sensors. The processor may be configured to process the control signal to determine content to be displayed on a user interface. The display may be configured to display the determined content on the user interface.

Aspects of the disclosure provide for mechanisms for providing muting functions for a piano system. In some embodiments, a piano system according to the disclosure includes a plurality of linkage structures coupled to a plurality of keys, a plurality of strings corresponding to the plurality of linkage structures, and a muting unit configured to place at least one elastic structure at a first position to implement a first mode for the piano system. In some embodiments, the first position is located between the linkage structures and the strings. In the first mode, the elastic structure may be placed at the first position to prevent an interaction between at least one of the linkage structures and the strings when one of the plurality of keys is depressed.

The keyboard sustain pedal stabilizer is for use with a keyboard sustain foot pedal. The stabilizer comprises a stabilizer base, a pedal-retention area for retaining the keyboard sustain foot pedal, a pair of sidewalls and an end-wall. The stabilizer base, the pair of sidewalls, the end-wall, and the pedal-retention area are made of one-piece of material. The keyboard sustain pedal stabilizer may be made of one-piece of material, the one-piece of material being a natural rubber, a synthetic rubber, or a blend of one or natural rubbers and one or more synthetic rubbers. The keyboard sustain pedal stabilizer has no moving parts. The top surface of the keyboard sustain pedal stabilizer has non-slipping properties and the underside of the device has non-skid properties. An opening for positioning a foot pedal cord is disposed in either an end-wall, a sidewall, or between the end-wall and a sidewall.

The present disclosure relates to a method and system for providing tutorial functions. The method may include obtaining a piece of music selected by a user; determining a display mode that configures one or more display categories and a layout of the one or more display categories on a user interface; obtaining one or more content items corresponding to the one or more display categories, respectively, the one or more content items being associated with the piece of music; and generating an instruction to display the one or more content items on the user interface according to the layout.

The present disclosure relates to a method and system for calibrating a musical device. In some embodiments, a method for calibrating a musical device includes: energizing an actuator to actuate a key using a force corresponding to a first intensity level; obtaining, from a sensor, a first sensor signal representing motion information of the key corresponding to application of the force; and calibrating the musical device based on the first sensor signal.
