ABSTRACT
From the viewpoint of development of the magnetic fluid emitter, operating at the lower boundary of the sonic frequency range, it is interesting to consider the studies [27-30, 214-217] describing the oscillatory systems with controlled magnetic fluid inserts. In particular, in [28-30, 215-218] studies were carried out of the oscillatory system with the magnetic fluid inertia element, ‘spring-loaded’ by an isolated gas cavity and the elasticity of the ponderomotive type. Such a system can be regarded as the magnetic fluid membrane (MFM), with the property of receiving-emitting sound and electromagnetic pulses.
