AUTOMATIC MUSICAL INSTRUMENTS (non-musical aspects of toy instruments A63H5/00; sound recording or reproducing G11B; working in association with recording or reproducing apparatus G11B31/02)

Description

G10F covers automatic and mechanical musical instruments that generate music without requiring real-time human performance. This includes player pianos, music boxes, barrel organs, and similar devices actuated by stored control mechanisms such as punched cards, perforated rolls, or mechanical cams. The classification encompasses the mechanical, electrical, and pneumatic systems that control note selection, timing, and dynamics, as well as synchronization mechanisms for coordinated sound production. Digital and electronic control systems for automatic music generation are also included where they directly replace or augment traditional mechanical control methods.
