Abstract
Sounds in different frequency range are generated from the rear, top and/or front face of the musical tone apparatus, sounds are generated and spread in all directions around the musical tone apparatus, and the tones sound very realistically acoustic. Vibration of the sound board does not resonate, tones generated from the sound board are not changed unintentionally, and tones of real acoustic musical instruments are realized. Vibration from the sound board is not directly transferred to the whole musical tone apparatus, by means of not allowing the sound board to touch the body of the musical tone apparatus and of pressing and fixing the soundboard to the attachment component with the thickness of the attachment component compressed.
Claims20
A musical tone apparatus comprising:
- a keyboard for instructing generation of plural tones in different pitches from high to low ranges;
- a back sound generator which generates sounds backward of the keyboard;
- upper sound generators which generate sounds upward of the keyboard in the different frequency range from that of the said back sound generator;
- fore sound generators which generate sounds forward of the keyboard in the different frequency range from those of the said back and upper sound generators;
- and
- a wall which is detected to exist near the back of the musical tone apparatus.
A musical tone apparatus comprising:
- a sound board which vibrates and generates sounds;
- an electromagnetic driver attached out of the center of said sound board for converting tone signals composed of plural kinds of tone to mechanical change and driving said sound board of a musical instrument to generate sounds;
- plural numbers of long and thin sound sticks attached to the surface of said sound board with said electromagnetic driver mounted on each space of various width between the sound sticks;
- and
- a space between said sound board and said musical tone apparatus is completely sealed.
A musical tone apparatus comprising:
- a sound board of a musical instrument which vibrates and generates sounds;
- an electromagnetic driver for converting tone signals composed of plural kinds of tones to mechanical change and driving said sound board of a musical instrument to generate sounds;
- an attachment component mounted on the body of the musical tone apparatus for contacting the margin of said sound board;
- a flexible intervenient between the attachment component and the margin of said sound board;
- and
- a space between said sound board and said musical tone apparatus is completely sealed.
