This technical solution was adopted as a prototype of the present invention in part of the device.

Its disadvantage is that the well-known voice plate does not allow receiving sound of sufficiently high strength, and also does not fully reveal all the harmonics of the timbre.

The task is to increase the sound strength and sound quality of a pneumatic reed musical instrument.

The technical result is an increase in sound power and a change in its timbre by adding to the traditionally extracted sound from the vibration of the tongue of sound from the oscillation of the frame of the voice plate on which the tongue is installed.

The task is solved due to the fact that in the method of extracting sound in a pneumatic reed musical instrument, including the creation of a directional air stream, the impact of the jet on the tongue of at least one voice plate and the formation of a sound wave from the vibration of the tongue, according to the present invention, additionally form the sound wave from the oscillation of the frame of the voice plate on which the tongue is installed.

To implement the described method, the voice plate of the sound-generating device of a pneumatic reed musical instrument, comprising a frame with a through opening, a tongue fixed to one of the frame surfaces on one side of the opening and made possible, when it is rejected, to enter the frame opening with a minimum gap between the edges of the uvula and the walls opening, and a flexible valve mounted on a different surface of the frame according to the present invention; the voice bar is provided with a sound conductor from frame oscillations and in which the tab is attached, the sound conductor is attached to one side of the frame, and the other side - to the resonator sound generating device.

The sound conductor from the frame oscillations can be of any shape, for example, it can be made in the form of a rod, plate or protrusion.

The sound conductor from the frame oscillations can be made of any material, for example, from metal, wood or plastic.

Due to the fact that the method of extracting sound in a pneumatic reed musical instrument, besides the formation of a sound wave from the vibration of the tongue, additionally includes the formation of a sound wave from the oscillation of the frame of the voice bar on which the tongue is installed, the sound from the oscillation of the frame of the voice is added to the traditionally extracted sound from the oscillation the lath on which the tongue is mounted, due to which an increase in the sound power and a more complete disclosure of the harmonics of its timbre occurs.

Due to the fact that the voice plate of the sound-generating device of a pneumatic reed musical instrument is equipped with a sound conductor from the oscillations of the frame on which the tongue is fixed, and the sound guide is attached to one side of the sound frame and the other side to the sound-forming resonator, the sound vibrations from the tongue are transmitted on the frame, which itself also begins to oscillate, and its sound vibrations are transmitted to the conductor of sound vibrations, and from there to the resonator, which forms the additional nny sound wave. Traditionally, the extracted sound from the vibrations of the tongue and the sound from the vibrations of the frame of the voice plate add up and amplified by the resonator, which causes an increase in the strength of the extracted sound and a more complete disclosure of the harmonics of its tone.

At the same time, the conduction of the sound conductor from wood, due to the acoustic properties of this material, makes it possible to best transmit the sound from the oscillation of the voice plate frame to the resonator.

The essence of the utility model is illustrated by drawings, which depict:

- in fig. 1 - a general view of the voice plate of a sound-forming device with a resonator, connected by two sound conductors;

- in fig. 2 is an enlarged view of A from FIG. one;

- in fig. 3 is an enlarged view of B from FIG. 2;

- in fig. 4 is a fragmentary view of the voice plate illustrating the location of the valve on the opposite side of the frame.

When implementing the claimed method of extracting sound in a pneumatic reed musical instrument creates a directed stream of air, which, acting on the tongue 3 of the frame 1 voice bar, generates a sound wave from the vibration of the tongue 3, which is amplified by the resonator 6 sound-generating device. The vibrations of the tongue 3 are transmitted to the frame 1 of the voice plate on which the tongue 3 is mounted. In this case, the oscillations of the frame 1 of the voice bar form an additional sound wave, which is transmitted by the sound conductor 5 to the resonator 6 of the sound-forming device.

The claimed method can be implemented in a pneumatic reed musical instrument, in which the voice plate of the sound-forming device is installed. A pneumatic reed musical instrument contains right and left semi-bodies with decks, keys, buttons and a sound-generating device, in particular, connected by a fur, the sound-forming device is equipped with resonators, on which vocal strips are fixed, containing at least one frame with a through opening, a tongue fixed to one of the surfaces of the frame on one side of the opening and made with the possibility of its rejection of the entry into the opening of the frame with a minimum gap between the edges of the tongue and the walls of the opening, and g A side valve mounted on another surface of the frame with the ability to block the opening, while the voice bar is provided with a sound conductor from the frame oscillations on which the tongue is fixed. The sound conductor is made in the form of a metal rod, which is fastened to one side with a threaded connection to the frame, and the other side to the resonator of the sound-generating device with the same connection.
