- Способ возбуждения электроакустического преобразователя при изменяющейся нагрузке, который заключается в том, что на преобразователь подают электрические импульсы возбуждения с длительностью не более половины периода его собственных механических колебаний на резонансной или кратной ей частоте, периодически прекращают подачу импульсов возбуждения и возобновляют их подачу по сигналу обратной стрикции на скорректированной частоте, отличающийся тем, что подачу возбуждающих импульсов возобновляют в момент времени, соответствующий фазе наибольшей чувствительности преобразователя, причем возбуждающие импульсы подают на частоте и в фазе колебаний преобразователя в этот момент времени.
