Automatic tuning system for piano - is formed by applying defined tension to each string by attaching weight to its free end
摘要
An automatic tuning system for a piano is formed by attaching a defined weight (4) to the end of the string which generates a particular note. The string (1) passes over a bridge (6) and then around a roller (2). The roller is mounted on a shaft (3) which is mounted on a metal plate (5). A defined weight (4) is then attached to the free end of the string. The magnitude of the weight for each string of the piano is determined by the piano tuner when the piano is initially tuned. USE/ADVANTAGE - Automatic tuning system for a piano. The piano never needs re-tuning.
