Abstract
An electronic keyboard instrument in which the efficiency of sound emission is enhanced by preventing a soundboard portion having a large vibration amplitude from being hidden by a musical score plate to make sound emission of the soundboard to be hardly hindered by the musical score plate. A musical stand device is disposed rearward of a key-depression part of a keyboard and right above the soundboard, and has a musical score plate disposed close to and parallel to an upper surface of the soundboard when the musical score plate is in a fallen state. The soundboard is excited for sound production by transducers disposed on a lower surface of the soundboard. The transducers are disposed at positions where the transducers do not overlap, as viewed in plan, the musical score plate which is in the fallen state.
