- the operating principle of the proposed distributor is as follows.
- the voltage signal arising at the output of the amplifier causes a current in the acoustic coil of the EDG.
- the magnetic system interacts with the constant radial field of the magnetic EDH system, forming the axial force that causes the EDG diffusion to move. This movement occurs due to the radial expansion of the diffusers of the Kolets bending waves.
- the EDG is an effective signal only at that frequency, at short the sound wavelength in the air is larger than the diameter of the diffuser. In this frequent region, the reactive (vector) component of the radiation resistance is much higher than the active (scalar) one. Therefore, the basis of radiation is made up of a reliable, unnecessary for itself, reactive
- the entire system even if it is performed in an absolutely linear manner, experiences a number of distortions in the form of optional distortions associated with the movement of the radiating amplifier.
