Description: Method for acoustic signal transmission to biological beings The invention relates to the field of sound engineering and more particularly, to methods for acoustic energetic transmission to biological beings. It is known a method for electric energetic transduction into acoustic energy and transmission to biological beings with radiation of the acoustic power to the environment as shown in Dynamic Loudspeakers by LA. Aldoshin, Radio and Communication, 1989. Drawbacks of this method are large required acoustic power and distortions arising in acoustic signal transmission of a non-periodic nature. An object of the invention is lowering of the required power of acoustic vibrations source, reduction of distortions, upgrading of quality and authenticity for acoustic signal transmission to biological beings. The object is achieved by the transduction of electric signals into mechanic vibrations with a transducer by way of direct contact of a transducer to biological beings. A presence of a new sum total of features in the preferred method, namely: "... mechanic vibrations for electric acoustic signal transduction are transmitted by direct contact of a transducer to biological beings" determines an accordance of the preferred technical embodiment to a criterion "novelty". For checking the preferred technical embodiment for an accordance to the criterion "essential distinctions" a comparison of its distinguish features had been compared with feathers of well known technical embodiment which showed that a sum total of such features as: "... mechanic vibrations for electric acoustic signal transduction is transmitted by way of direct current of a transducer to biological beings" in well known technical embodiments is absent that lets to draw a conclusion about an accordance of the preferred technical embodiment to the criterion "essential distinctions". An accordance of the preferred technical embodiment to the criterion "positive effect" is determined so that in the preferred method a new sum total of features, namely: the transmission of mechanic vibrations for electric acoustic signal transduction by way of direct contact of a transducer to biological beings lets to achieve an object of the invention, namely lowering of the required power of acoustic vibration source, reduction of distortions, upgrading of quality and authenticity for acoustic signal transmission of a non-periodic nature gives the right to draw a conclusion about an accordance of the preferred technical embodiment to the criterion "positive effect". The preferred embodiment of the invention is by way of example illustrated in the accompanying drawings wherein: Figures 1 and 2 show a device according to the preferred method. It is provided a device comprising a belt 1 and an electric acoustic signal transducer into a mechanic displacement. A transducer 2 contains a magnet 3, the magnetic brackets 4, a coil 5 and a body 6. A transducer is attached to a belt 1 through the hard and flexible coupling. The preferred method is realized as follows. A belt 1 with a transducer 2 is attached to biological being, electric acoustic signals are transmitted to a coil 5 of a transducer 2 and acoustic vibrations are transmitted through a belt 1 of the hard coupling by way of its direct contact to biological being. The preferred method for acoustic signal transmission to biological beings by the transmission of mechanic vibrations of an electric acoustic signal transducer by way of direct contact of a transducer to biological being lets to lower the required power of acoustic vibration source, to reduce distortions and also to upgrade quality and authenticity for acoustic signal transmission to biological beings.

Claims: Claim A met rfor acoustic signal transmission to biological beings, characterised in that mechanic vibrations of a transducer of electric acoustic signals are transmitted by way of direct contact of said transducer to said biological beings.
