Description

[Detailed description of the invention] The present invention relates to a novel musical instrument.

Traditionally, there was a musical instrument known as the Taishogoto, but it had the disadvantage that the playing method and tone were simple and lacked variety.

It is an object of the present invention to overcome these conventional drawbacks and provide a musical instrument that produces a wide variety of tones.

The present invention will be explained below based on the embodiments shown in the drawings. In the drawings, 1 is a barrel, 2 is a key case, 3 is a key, 4 is a string, 5 is an electric pickup, and 6 is a knob for adjusting volume and tone change. , 7 is a switch, 8 is a hand rest, 9 is a vibration arm, 10 is a key arm, 11 is a sound cutting cushion, 12 is a support shaft, 13 is a spring for pushing up the key, 14
is a key switch, 15 is a conductor connected to the sound generation circuit,
Reference numeral 16 indicates a bridge, 17 indicates a bridge roller used for the string pressed by the vibration arm 9, and 18 indicates a string stop.

A key arm 10 is attached to each key 3 as shown in FIG. 2, and by pressing the key 3, the string 4 is pressed against the fret board and the scale of the string is determined. A key switch 14 is provided which closes when the key 3 is pressed, and when this key switch closes, a musical scale corresponding to the position of the key 3 is generated.

The electrical circuit can be realized with a configuration similar to that of a general electronic organ.

Therefore, if you play the strings with a pick while holding down the key, the vibrations of the strings will be detected and amplified by the electric pickup 5, and an electronic organ-like sound will be added using the key switch, allowing you to enjoy a richly varied performance. Can be done.

In addition to being able to hear the sound through the built-in speaker,
It is also possible to connect to an external amplifier.

Note that a sound-cutting cushion made of felt or rubber may be attached to the part of the key arm 10 that touches the strings to eliminate the harsh high-pitched noise that occurs when a key is pressed or released.

For example, for a string for medium notes, a vibration arm 9 is attached between the bridge and the string stopper 18 as shown in Figure 3, and the tension of the string can be changed by pressing and releasing the arm with the belly of the hand. If you pick up a pick with your fingers and play the strings, you can produce a vibrato sound, allowing you to play with variety.

In this case, if a rotatable bridge roller 17 is used instead of a fixed bridge, the tension of the string can be smoothly changed.

As mentioned above, according to the present invention, in addition to playing with normal strings, a sound corresponding to the height of the pressed key is generated electrically, so it is possible to play both at the same time or by switching between them one by one. This has the effect of allowing you to perform in a variety of interesting ways.
