FIELD: physics, acoustics.SUBSTANCE: invention relates to acoustic means of reproducing sound. The electrodynamic sound reproducing head comprises an audio electric signal source, a sound vibration generator interacting with an elastic medium, series-connected modulator, matching device and high-voltage transformer. The sound vibration generator is in the form of two electrodes separated by a distance which enables to generate an electric arc. The input of the modulator is connected to the output of the audio electric signal source, and the outputs of the high-voltage transformer are connected to the electrodes, the output of the modulator is connected to the matching device which facilitates signal strength and resistance matching with the input of the high-voltage transformer. The output of the matching device is connected to the input of the transformer.EFFECT: high sound quality.1 dwg |
