Abstract
Способ возбуждения электроакустических преобразователей, состоящий в том, что их возбуждают периодическим электрическим сигналом прямоугольной формы резонансной частоты и компенсируют их реактивные составляющие при помощи согласующих элементов, отличающийся тем, что из прямоугольного электрического сигнала возбуждения выделяют первую, третью и пятую гармоники, которые подают на отдельные электроакустические преобразователи, каждый из которых изготавливают и настраивают при помощи согласующих элементов на соответствующую резонансную частоту нечетной гармоники, соединяют эти электроакустические преобразователи с согласующими их элементами между собой параллельно и подключают к выходу генератора периодических прямоугольных импульсов.The method of excitation of electro-acoustic transducers, consisting in the fact that they are excited by a periodic electric signal of a rectangular shape of a resonant frequency and compensate for their reactive components using matching elements, characterized in that the first, third and fifth harmonics are separated from the rectangular electric signal of excitation, which are fed to separate electro-acoustic transducers, each of which is manufactured and adjusted using matching elements to the appropriate reason waistband frequency odd harmonic, the electroacoustic transducers are coupled with their matching elements in parallel to each other and connected to the output of the generator of periodic rectangular pulses.
