An electronic keyboard instrument capable of suppressing warpage of a keybed having a keyboard placed thereon and improving the appearance of the instrument by shared use of a backboard covering an instrument body and a speaker box. A piano body of an electronic piano has a keybed. A bottom board is disposed below the keybed in a manner spaced therefrom and extends further rearward than a rear end thereof. A front board is erected on a front end of the bottom board and connected to the keybed. The speaker box accommodates a speaker. A screen board is erected rearward of the front board in the speaker box on the bottom board, and connected to the keybed. A backboard is connected to the rear end of the bottom board in a manner covering the rear sides of the piano body and the speaker box.

The invention discloses a digital sound production device of a vertical piano, which comprises a piano body (1) and loudspeakers (4), wherein the rear part of the piano body (1) is provided with a hollow box body; a sound box board (8) is arranged in the hollow box body on the rear part of the piano body (1) transversely; the hollow box body is partitioned into an upper high-frequency sound box (2) and a lower low-frequency sound box (3) through the sound box board (8); a clapboard (5) is arranged in the low-frequency sound box (3); two loudspeaker holes are formed on the sound box board (8); the loudspeakers (4) are arranged in the two loudspeaker holes; and the back board walls of a left sound box body and a right sound box body of the low-frequency sound box (3) are provided with a guide hole (6) respectively. By the device, the sound box board is used for separating the high-frequency sound box from the low-frequency sound box, the low-frequency sound box is partitioned into two box bodies through the clapboard, and the problems of phase interference and short circuit of low-frequency sound are effectively solved; and the device has fine, well-bedded and ambient tone quality and can bring strong hearing sense shock to a listener.

In an erroneous opening prevention mechanism according to the present invention, a hook and a hook support are loosely engaged with one another when a front lid, folded back on a back lid, is unfolded, or laid flat. If an attempt to raise the whole lid laid flat on a grand piano main body is made, it is impossible to raise the lid due to the locking of the hook and the hook support. When the front lid is folded back onto the back lid, on the contrary, the hook and the hook support are released from one another and, therefore, the whole lid can be raised. Accordingly, the erroneous opening prevention mechanism prevents the whole lid from being raised without first folding back the front lid.
