Изобретение относится к области акустики и может быть использовано для создания тональных сигналов большой мощности в газовой или жидкостной среде для целевой сигнализации. Цель - увеличение излучаемой мощности и диапазона частот акустического излучения, а также стабильности частоты тона. Для этого генератор выполнен в виде резонансной акустической камеры, образованной пластиной и стенками канала, через который проходит воздух, или иной газ, или жидкость. 6 п. ф-лы., 4 ил.The invention relates to the field of acoustics and can be used to create high-power tones in a gas or liquid medium for target signaling. The goal is to increase the radiated power and frequency range of acoustic radiation, as well as the stability of the tone frequency. For this, the generator is made in the form of a resonant acoustic chamber formed by a plate and the walls of the channel through which air, or another gas, or liquid passes. 6 pp., 4 ill.
