Claims (1)

Способ громкоговорящей связи, отличающийся тем, что, с целью упрощения схемных решений и получения полного дуплекса со средним уровнем громкости речи первого абонента через электроакустический(ие) излучатель(ли) звука не менее 60 дБ относительно нулевого уровня звукового давления - 2·10-5 Па при расстоянии второго абонента от электроакустических преобразователей не менее 3 м, электроакустический(ие) излучатель(ли) звука располагают в корпусе так, что он(и) распространяет(ют) звуковые колебания речи перпендикулярно принимаемым звуковым колебаниям речи электроакустическим(ми) приемником(ми) звука с осями симметрии диаграмм направленностей звуковых сигналов речи излучающего(их) и принимающего(их) электроакустических преобразователей в одной(их) плоскости(ях), причем электроакустические преобразователи акустически изолируются внутри корпуса громкоговорящего аппарата.A loud-speaking communication method, characterized in that, in order to simplify circuit solutions and obtain a full duplex with an average level of speech volume of the first subscriber through an electro-acoustic emitter (s) of sound not less than 60 dB relative to the zero sound pressure level - 2 · 10 -5 Pa at a distance of the second subscriber from the electro-acoustic transducers of at least 3 m, the electro-acoustic (s) emitter (s) of sound are placed in the case so that it (s) propagates (s) the sound vibrations of speech perpendicular to the received sound pitch to speech baths by the electro-acoustic (s) sound receiver (s) with symmetry axes of the radiation pattern of speech sound signals emitting (them) and the receiving (them) electro-acoustic transducers in one (their) plane (s), and the electro-acoustic transducers are acoustically isolated inside the body of the loud-speaking device.
