Abstract text
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.Claims
1. 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; andfore sound generators which generate sounds forward of the keyboard in the different frequency range from those of the said back and upper sound generators.
2. The musical tone apparatus according to claim 1, wherein:a music stand is installed near said keyboard;plural numbers of said upper sound generators are installed;some of the upper sound generators are positioned behind said music stand; andthe other upper sound generators are positioned before or beside said music stand.
3. The musical tone apparatus according to claim 1, wherein:it is detected that a wall exists near the back of the musical tone apparatus, and it is reduced high, middle or low range portion of the frequencies of sounds generated from said upper, fore or back sound generator.
4. The musical tone apparatus according to claim 1, wherein:at least one of said back, upper and fore sound generators is a sound board
of a musical instrument which vibrates and generates sounds; andan opening is formed facing the sound board installed on the opposite side.
5. The musical tone apparatus according to claim 1, wherein:at least one of said back, upper and fore sound generators comprises a sound board of a musical instrument which vibrates and generates sounds, and an electromagnetic driver installed to said sound board 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; andas least one of the others comprises speakers.
6. The musical tone apparatus according to claim 1, wherein:at least one of said back, upper and fore sound generators is a sound board of a musical instrument which vibrates and generates sounds;at least one of the others has plural numbers of speakers; anda plural numbers of channel signals to form sound image are sent to each of the speakers.
7. The musical tone apparatus according to claim 1, wherein:a long connector is fitted to connect the inner side of the sound board and the inner side of the opposite board,
which is a part of the body of the musical tone apparatus and faces to the sound board installed in the musical tone apparatus.
8. The 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; andplural 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.
9. The musical tone apparatus according to claim 8, further comprising:a keyboard for instructing generation of plural tones in
