Embodiment Construction

[0054] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. figure 1 It is the soundboard speaker 30 to which this embodiment is applied (refer to figure 2 ) is a perspective view of the electronic organ 1 . Directional arrows in the figure indicate up, down, left, and right with the player's side as the front. The electronic keyboard 1 is an electronic keyboard instrument that detects the key state of the keyboard 15 by using a sensor switch, generates a tone signal by performing arithmetic processing on the detection result, and emits sound from a plurality of speakers included in the main body. In the electronic keyboard 1 of the present embodiment, the soundboard speaker 30 is used as one of the plurality of speakers in charge of the bass range, and is arranged on the back of the piano body.

[0055] The upper parts of the pair of left and right side plates 8 are connected by the top plate 2 , and the br...

Abstract

To provide a soundboard speaker of a digital piano that displays more favorable acoustics by devising the arrangement of the vibration unit and ribs. In a soundboard speaker (30) of a digital piano which transmits vibration generated by a vibration unit (32) mounted at one face side of a diaphragm (31) by ribs Ka to Kd mounted at the other face side of the diaphragm (31) so that sound is produced from the whole of the diaphragm (31), the vibration unit (32) is disposed at a position to overlap the rib Kb when the soundboard speaker (30) is viewed head on. The diaphragm (31) in a horizontally long rectangular shape, and the ribs Ka to Kd consisting of prismatic members are disposed on the surface of the diaphragm (31) parallel to each other and in an inclined manner with respect to the vertical direction. Only one vibration unit (32) is arranged for aiming at the diaphragm (31). The vibration unit (32) is configured above the central part of the diaphragm (31) in a manner of deviating to a random direction selected from left and right.

Description

technical field [0001] The present invention relates to a soundboard speaker for an electronic piano, and more particularly to a soundboard speaker for an electronic piano that emits sound from the entire vibrating plate by operating a vibrator fixed to a flat vibrating plate. Background technique [0002] Conventionally, in an electronic keyboard, which is an electronic keyboard instrument, a soundboard speaker using a structure that reproduces the soundboard of an acoustic piano, which is a natural musical instrument, is known. The soundboard speaker operates the vibrator fixed on the large-scale vibrating plate installed vertically on the back of the electronic organ to emit sound from the entire vibrating plate, thereby, the vibration of the string struck by the hammer linked to the keyboard can be transmitted It is passed to the soundboard to obtain the sound quality close to that of an acoustic piano that emits sound from the soundboard as a whole.
