Abstract
Изобретение относится к области акустического приборостроения, а именно к конструированию ненаправленных преобразователей, и может быть использовано при проведении различного рода океанографических исследований, измерении объемного рассеяния, проведении различного рода гидроакустических измерений, в системах звукоподводной связи, для работы гидроакустических маяков и во многих других случаях, когда возникает необходимость в излучении звуковых волн. Электроакустический ненаправленный преобразователь содержит пьезостержень, две одинаковые осесимметричные накладки, выполненные в виде сплошных конусов, соединенных армирующей стяжкой, и герметизирующие прокладки, установленные в месте сопряжения накладок, которые обращены основаниями друг к другу, а со стороны этих оснований выполнены глухие цилиндрические отверстия, не превышающие по глубине половины длины пьезостержня, который располагается в них и жестко прикрепляется своими торцами к торцам указанных отверстий. Технический результат заключается в возможности получения эффективного ненаправленного излучения (приема) звуковых волн в области резонансной частоты предлагаемого преобразователя в диапазоне единиц кГц и ниже.The invention relates to the field of acoustic instrumentation, in particular to the design of non-directional transducers, and can be used when conducting various kinds of oceanographic research, measuring volume scattering, conducting various types of hydroacoustic measurements, in underwater communication systems, for the operation of hydroacoustic beacons and in many other cases, when the need arises to emit sound waves. The electroacoustic non-directional transducer contains a piezo rod, two identical axisymmetric pads made in the form of solid cones connected by a reinforcing tie, and sealing gaskets installed at the interface of the pads, which face each other with their bases, and blind cylindrical holes are made from the side of these bases, not exceeding along the depth of half the length of the piezoelectric rod, which is located in them and is rigidly attached by its ends to the ends of the indicated holes. The technical result consists in the possibility of obtaining effective non-directional radiation (reception) of sound waves in the resonant frequency range of the proposed converter in the range of units of kHz and below.
