FIELD: physics; radio.
SUBSTANCE: invention relates to radio engineering. The technical result is achieved due to that, the acoustic device for a mobile communication terminal for generating vibration sound uses a display window as a vibration plate. As a result, restrictions on reproducing low-frequency sound are overcome. The device also has an elastic supporting element for the display window, a vibrator in form of a magnet placed on the display window and a magnetisation generator placed in front of the magnet.
EFFECT: increased efficiency of reproducing sound in the low-frequency range.
