ELECTRONIC DEVICE Russian patent published in 2017 - IPC H04M1/02 

FIELD: physics.

SUBSTANCE: electronic device comprises a panel, a body configured to support the panel, a piezoelectric element attached to the panel. The panel is deformed due to deformation of the piezoelectric element, so that the sound of air conduction and the sound of bone conduction are transmitted to the object that is in contact with the deformed panel. Vibration occurs in the area of the panel, which is larger than the area having a length corresponding to the distance from the lower leg of the counter-wedge to the counterweight, and the width corresponding to the distance from the tragus to the antiparticle of the person's ear. The panel includes a plurality of portions that are configured to vibrate in a direction intersecting with the panel surface and, in each of the plurality of portions, a value indicative of the amplitude of the vibration shifts from plus to minus and vice versa over time. The panel has a size larger than the size of the ear. The piezoelectric element is attached to the back surface of the panel.

EFFECT: increasing the reliability of the device, expanding its functionality.
