ACOUSTIC OUTPUT DEVICES Russian patent published in 2023 - IPC H04R17/00 B06B1/06 

FIELD: acoustics.

SUBSTANCE: invention relates to sound emitters. The device contains the first vibration element, the second vibration element and the piezoelectric element. The piezoelectric element may cause the first vibration element and the second vibration element to vibrate in response to an electrical signal, wherein the first vibration element may be attached to a first attachment point on the piezoelectric element, the second vibration element may be attached to a second attachment point on the piezoelectric element at least through the first elastic element, the second vibration element can be connected to the third attachment point on the piezoelectric element at least through the second elastic element, and in the vibration direction of the second vibration element, the first elasticity coefficient of the first elastic element may differ from the second elasticity coefficient of the second elastic element.

EFFECT: improved sound quality.
