The utility model adopts the technical proposal that:

the utility model provides an electric piano keyboard, its characterized in that includes key, LED lamp circuit board, the key includes black key and white key, the white key adopts the printing opacity material, every the white key back marks the note mark, LED lamp circuit board install in the key below, every LED lamp on the LED lamp circuit board corresponds a white key, LED lamp circuit board passes through the switch and is connected with the power electricity.

The utility model discloses utilize the light transmissivity of the white key of electric piano, set up the LED lamp below every white key to mark the note at the white key back, when the beginner uses the electric piano, open the LED lamp, because the light transmissivity of the white key of electric piano, the note marked at the white key back shows on the key, thus help the beginner practice remember the corresponding note of every key; when the skilled person uses the electric piano, the LED lamp is turned off, no marked trace exists on the key, the electric piano is conveniently played by the skilled person freely, and the interference of the mark is avoided.

Preferably, the note mark is located at the lower end of the back of the white key, and the LED lamp is installed right below the note mark. The note mark is marked on the back of the white key and close to one end of a player, each LED lamp on the LED lamp circuit board is arranged right below the note mark on each white key, and at the moment, when the LED lamp is turned on, the note mark is displayed most clearly and is more convenient for the player to watch.

Preferably, the light-transmitting material is one of ABS plastic, polystyrene, and synthetic resin.

Preferably, the note marks are drawn by using a shading paint, and the selected shading paint is black baking varnish. And after the LED lamp is turned on, the note mark on the white key is opaque, and the part without the note mark emits light, so that the note mark is more clearly displayed. The shading paint can also adopt baking varnish with other colors, and musical notes marked by black baking varnish are more clearly marked on white keys.

Preferably, the LED lamps on the LED lamp circuit board are connected in series, the LED lamp circuit board switch is turned on, all the LED lamps are turned on, and the note marks on each white key are displayed, so that a practicer can more easily and quickly memorize the notes corresponding to each key.

The utility model also provides an electric piano, electric piano includes foretell electric piano keyboard.

The utility model discloses utilize the light transmissivity of the white key of electric piano, through the switch of LED lamp, make the note mark at the white key back of electric piano show or disappear, both satisfied the demand that the beginner practised the note that every key of memory corresponds, can not produce the interference in the vision to the skilled person again when playing electric piano, the utility model discloses on can being applied to current electric piano, easily repacking and with low costs, convenient to use is fit for promoting in the electric piano classroom of school.
