Abstract

(57) [Summary] [Issues] The present invention is concerned with the sound volume and tone of the percussion-table desk piano, in which a resonance box is provided with a soundboard so that the required volume and beautiful tone are produced. [Solution] According to the present invention, a resonance box 3 (having a vibration sound intake hole 4a in a top plate) is provided in a main body 1, and the top plate is used as a soundboard 4
And attach the sound plate 2 to it with studs 5,
It is struck by a hammer pattern 6 and a hammer head 6a that move when the keyboard 7 is depressed so as to produce a large volume and a beautiful tone.

Description

[Detailed description of the invention]

[0001] The present invention is a percussion board type desk piano provided with a resonance box and a soundboard.

[Prior art] As a sound source, a sound plate (made of metal) attached to a frame base was hit with a hammer to produce sound, so that the sound volume was low and the sound was tasteless.

[Problems to be Solved by the Invention] In addition to the vibration sound caused by the impact of the sound plate, the sound obtained by synthesizing the resonance sound of the resonance box and the vibration sound of the soundboard also increases in volume. The sound quality is very beautiful, and the above-mentioned disadvantages are to be solved.

[Means for Solving the Problems] In the present invention, a resonance box (having a vibration sound intake hole in a top plate) is provided below a sound plate, and the top plate is used for the function of a sound board. The problem was solved by making the sound source relatively large for ease of use and hitting the sound source with the sound plate attached to it with a hammer to produce sound.

[0005] [Embodiment of the invention] When a sound plate is struck and vibrated, the vibration sound is, in addition to the vibration sound of the sound plate itself, one of the vibration sound intake holes formed in the sound plate. Resonance occurs in the resonance chamber to create a resonance sound, and one is caused by the vibration sound of the soundboard that is transmitted to the soundboard through the soundboard mounting studs, the soundboard holding material, etc., and vibrates the soundboard. A beautiful synthetic sound with a large volume can be obtained.

An embodiment will be described below with reference to the accompanying drawings. 1 is a main body, 2 is a sound plate serving as a sound source, 2a is a sound plate mounting hole formed in the sound plate 2, 3 is a resonance box, 4 is a sound board made of a relatively large top plate of the resonance box 3, 4a Is a hole drilled in the soundboard 4, which is a hole for taking in the vibration sound of the resonance box 3, 5 is a rivet or wood screw, etc., a sound plate mounting bracket, and 5a is a rubber, felt, etc. mounted on the sound plate mounting bracket 5. A sound board holding seat for holding the vibrating body softly, 6 is a hammer handle, 6a is a hammer head fitted to one end of the hammer handle 6, and 6b is a hammer handle hole drilled at the other end of the hammer handle 6. Through which the hammer head 6a moves circularly. Reference numeral 7 denotes a keyboard, which has a fulcrum in the middle. When the keyboard is pressed down, the other end rises to push up the hammer handle 6, and the hammer head 6a makes a circular motion. [Effects of the Invention] As described above, the percussion board-type desk piano of the present invention mixes three sounds, the vibration sound of the soundboard and the resonance sound of the resonance box, in addition to the vibration sound of the soundboard itself. You will get a sound.
