Abstract:
1. An electronic keyboard instrument comprising: a frame member; a keyboard which has a plurality of keys pivotably supported by the frame member; a lower case which is formed integrally with or separately from the frame member under the keyboard; and an electroacoustic transducer which is accommodated in a space between the keyboard and a bottom plate of the lower case, and which outputs an acoustic wave, wherein a lowermost portion of the electroacoustic transducer is mounted on a surface of a lowermost portion of the frame member or the lower case, and a lowermost portion of the keyboard is positioned above the lowermost portion of the electroacoustic transducer, wherein the acoustic wave outputted from the electroacoustic transducer is radiated outwardly through sound passages configured as gaps in the frame member and gaps between the plurality of the keys, and wherein the electroacoustic transducer is accommodated in the space such that a central axis of a front opening part of the electroacoustic transducer is inclined in a rear direction opposite of a front direction directed to a front end of the keys from a vertically up direction of the keyboard.
