Title:
ACOUSTIC OUTPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/206143
Kind Code:
A1
Abstract:
Embodiments of the present description provide an acoustic output device, comprising: a vibration element provided with a beam structure extending along a length direction; a piezoelectric element used for generating deformation in response to an electric signal, the deformation driving the vibration element to vibrate, wherein the piezoelectric element is attached to a first position of the beam structure, and the size of an attached area along the length direction does not exceed 80% of the size of the beam structure along the length direction; and a mass element connected to a second position of the beam structure, wherein the first position and the second position are distributed at intervals in the length direction, and the vibration of the vibration element drives the mass element to vibrate in a direction perpendicular to the length direction.
