Keyboard music instrument i.e. grand piano, has leg laminarly implemented to serve as sound reflection surface, where laminarly implemented leg is completely extended over non-curved longitudinal side of instrument

摘要

The instrument (1) has a leg (2) laminarly implemented to serve as a sound reflection surface. The laminarly implemented leg is completely extended over a non-curved longitudinal side of the instrument. The laminarly implemented leg has two regions that stand in contact to the base under normal assembly of the instrument. The leg optically forms an extension of a side of a housing of the instrument and/or a rear cover (4) of the instrument.
