Description

 The invention relates to the production of musical instruments such as a harp.

 Known musical instruments (USSR, a.s. N 1571649, G 10 D 7/12, 1988, a.s. N 1758669, G 10 D 17/00, 1989), containing a flat arcuate base with elongated cheeks and a tongue, cantilever connected to the base and placed in the gap between the cheeks.

 Famous musical instruments belong to the class of folk reed instruments, being a kind of musical instruments such as a harp. A distinctive feature of musical instruments of this type is the peculiar fastening of the tongue to the base, providing high quality instrument sound.

 Known kubyz advanced design (USSR, AS N 1234876, G 10 D 7/12, 1984), equipped with a wings, moving on the tongue and changing the structure and pitch.

 The presence of the backstage provides the ability to quickly tune the instrument to a given key, or to change the key directly during the game, thereby expanding the performance capabilities of the musician.

 The present invention is the creation of a musical instrument with enhanced performing and functional capabilities while maintaining the classical construction of the kubyz (harp) and the originality of the game on it.

 The problem is solved as follows.

 An electronic musical instrument kubyz (harp), containing a flat arcuate base with elongated cheeks and a tongue, located with a gap between the cheeks and connected to the base, is additionally equipped with a series-connected electronic tone generator and an acoustic modulator. The acoustic modulator is fixed on the arcuate part of the base in the plane of its longitudinal section so that the membrane of the acoustic modulator overlaps the surface of the tongue without touching the latter. The tone generator contains tone and frequency controls. In addition, the kubyz (musical instrument) electronic musical instrument is equipped with a microphone fixed above the tongue to the body of the acoustic modulator or to the base.

The supply of a kubyz (harp) with an electronic tone generator and an acoustic modulator significantly distinguishes it from well-known musical instruments such as a harp, namely:
- the proposed technical solution eliminates the need to press kubyz to the teeth. Moreover, kubyz, mounted, for example, on a tripod in front of the performer, frees the musician's hands. The latter has the opportunity with his hands to accompany himself on another musical instrument, which increases the usability of the proposed electronic musical instrument in an orchestral game;
- the presence of a tone generator and an acoustic modulator allows you to expand the variety of performed works and significantly increase the performing ability of the musician. In particular, it allows you to perform two-voice singing on one quiz;
- the proposed electronic musical instrument kubyz (vargan) eliminates the negative impact on the performer, as it eliminates the need to press the base to the teeth. That is, the instrument is available for play to musicians who do not differ in healthy teeth, as well as to people with disabilities who do not have one or both hands.

 The author knows the principle of reproducing sound on string and keyboard musical instruments by means of a tone generator and an acoustic modulator (for example, AS USSR N 1720087, G 10 H 1/10, 1989, AS USSR N 1749906, G 10 H 1 / 02, 1990). But the use of an electronic tone generator and an acoustic modulator in combination with kubyz (harp) is not known.

 In FIG. 1 schematically presents the electronic musical instrument kubyz (vargan).

 The electronic musical instrument kubyz (vargan) contains an arched base 1 with elongated cheeks 2, a tongue 3, electrically connected in series with each other, an electronic tone generator 4 and an acoustic modulator 5. The tone generator 4 is an electronic unit, the circuit of which is based on consumer radio elements . The tone generator 4 has tone and frequency controls (not shown in FIG.), Allowing you to change the key of the main melody. In this case, an industrially manufactured telephone acoustic modulator is used as an acoustic modulator, the overall dimensions of which are comparable with the overall dimensions of the base of 1 cubic meter.

 Playing the proposed electronic musical instrument kubyze (vargan) is carried out as follows.

 The tone generator 4, using the tone and frequency control knobs, sets the signal of the required tonality, which is supplied via an electric cord to the input of the acoustic modulator 5. When excited, the membrane of the acoustic modulator 5 transmits the vibrations of the specified tone and frequency to the tongue 3. The forced vibrations of the tongue 3 reproduce the sound of the tonality specified by the generator tones 4. The performer, holding the musical instrument by the base 1 in front of the lips, by means of the speech and breathing apparatus varies the sound of the tongue 3, without touching the last hand. Thus, the tone and frequency controls of the tone generator 4 provide the ability to change the harmonic of the fundamental tone and change the sound series. In this case, the overtones are changed by means of the speech apparatus of the performer.

The melody is output by changing the position of the lips (soundless singing), while a guttural sound can be connected, giving a two-voice:
- guttural sound - the first voice,
- lip singing - the second voice, kubyz (Vargan) at the same time sounds like an accompanying instrument. Such two-voice is not possible when playing famous musical instruments such as a harp.

 To enhance the sound of the melody above the tongue 3, a microphone is attached (not shown in Fig.), Giving a quart amplification of the sound. The microphone is made on the basis of a piezoelectric element; therefore, it has dimensions commensurate with a musical instrument and is attached to the case of the acoustic modulator 5 or to the base 1.

 The design of the proposed electronic musical instrument Kubyz (Vargan) is simple to implement and does not require special materials and technology.
