IMPEDANCE DEVICE AND SYSTEMS FOR SIMULATION OF HEAD EFFECT ON VIBRATION UNIT VIBRATION Russian patent published in 2023 - IPC H04R29/00 

FIELD: acoustics.

SUBSTANCE: invention relates to acoustics. The impedance device comprises a mass component, at least one elastic component and a stationary component, wherein the mass component is connected to the stationary component via at least one elastic component; a damping component located between the mass component and the stationary component and providing damping of the movement of the mass component relative to the stationary component. When the mass component contacts the external vibration unit, the mass component receives the vibration of the external vibration unit and moves relative to the stationary component, wherein the mass of the mass component is in the range of 0.5 to 5 g, the elasticity coefficient of at least one elastic component is in the range of 600 to 5000 N/m, the damping factor of the damping component is in the range of 1 to 4, and the impedance device provides the external vibration unit with a mechanical impedance in the range of 6 to 50 dB.

EFFECT: invention provides the possibility of simulating the area of the face in front of the human auricle.
