Abstract: 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: determining a first time corresponding to a first instruction that instructs a driving device to actuate a first component of a musical device using a first force; receiving first sensor data relating to motion information of the first component; determining a second time based on the first sensor data; determining, by a hardware processor, a first time deviation based on the first time and the second time; and calibrating the musical device based on the first time deviation.

Abstract: A heat dissipation system for a smart piano may include a heat dissipation driver, a heat dissipation device, a sensor, a protection circuit and a hardware processor. The sensor may be configured to detect a thermal parameter of an execution device of the smart piano. The protection circuit may be configured to analyze the thermal parameter to generate a protection signal. The hardware processor may be configured to determine a preset algorithm, generate a control signal according to the protection signal and the preset algorithm, and control a heat dissipation condition of the smart piano. The controlling the heat dissipation condition of the smart piano may include control an operation condition of the execution device and/or the heat dissipation device. The controlling may include controlling an output power of the execution device and/or the heat dissipation device.
