FIELD: physics, acoustics.
SUBSTANCE: method of generating and transmitting audio signal and a device to this end relate to acoustics and can be used to generate audio signals similar to high intensity broadband audio signals for various alarm systems. The device for generating and transmitting an audio signal has a power supply 1, an initiation unit 2, a pulsed high audio carrier frequency generator 3 with audio frequency range of 2-10 kHz, a low audio frequency pulse generator 4 with range of 200-800 Hz, a modulator 5, a power amplifier 6 and a high frequency audio radiator 7.
EFFECT: easy implementation, broad functional capabilities and high efficiency of radiating an audio signal perceived the same way as a broadband signal.
