Problems solved by technology

[0011] However, in the keyboard-type soundboard percussion instrument according to the second prior art, the overall length of the soundboard producing the lower pitch is longer
In particular, the soundboard width for the low register is wide and the overall length is long
The need to meet the above-mentioned soundboard size requirements causes a problem of reduced design freedom
For example, this would lead to an increase in the size of the overall instrument, especially if keyboard soundboard percussion instruments include a large number of soundboards in order to cover a wide range

Embodiment Construction

[0070] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing preferred embodiments of the invention.

[0071] figure 1 is a left side view of the keyboard musical instrument according to the first embodiment of the present invention, which is configured as a keyboard type soundboard percussion instrument including a resonance box. Roughly speaking, keyboard instrument 10 is similar in appearance to an upright piano, but does not include any strings. Instead, the keyboard instrument 10 includes a soundboard similar to that of a celesta and arranged in the upper half 10 a of the keyboard instrument 10 . When the soundboards are struck, each soundboard vibrates and produces a musical tone. The keyboard musical instrument 10 includes a resonance box in which tones generated by corresponding soundboards resonate therein. As a device for striking the soundboard, a device similar to an action device for a grandpiano inst...

Abstract

A tone plate is provided which makes it easy to reduce the entire length and width thereof, thus increasing the degree of freedom in design. The tone plate includes an antinode portion, front and rearends, and first and second supporting holes which are located closer to the front and rear ends than to the antinode portion and at which a vibration node can be formed. There are provided first andsecond mass concentrating portions extending toward the front and rear ends from locations on a side close to the first and rear ends with respect to the supporting holes. First and second thinner portions are respectively provided between the antinode portion and the supporting holes. The tone plate vibrates to generate a musical tone of a specific tone pitch when struck with being supported at the supporting holes.

Description

technical field [0001] The present invention relates to a soundboard for a keyboard-type soundboard percussion instrument, a method for manufacturing a soundboard, a tone generator device for a soundboard-type percussion instrument, and a keyboard-type percussion instrument, wherein the soundboard is suitable for The soundboard percussion instrument includes a soundboard and a resonance box for resonating therein the musical tone generated by the soundboard to vibrate when struck. Background technique [0002] As disclosed in Japanese Utility Model Publication (KoKai) No. H05-081895, a conventional keyboard-type soundboard percussion instrument includes a plurality of soundboards as sounding parts, each soundboard adapted to produce a specific pitch when struck. Tone (hereinafter referred to as the first prior art). Generally, the soundboards are formed as flat plates, and in most keyboard-type soundboard percussion instruments, the soundboards differ from each other mainly...
