Title:
ACOUSTIC OUTPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/020846
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present description is an acoustic output device, comprising a vibration element. The vibration element comprises a beam structure extending in a lengthwise direction. The beam structure comprises a piezoelectric layer for responding to an electrical signal to deform, wherein the deformation drives the vibration element to vibrate; and a mass element, wherein the mass element is connected to a first position of the beam structure, the vibration element vibrates to drive the mass element to vibrate in a direction perpendicular to the lengthwise direction; and in the lengthwise direction of the beam structure, the ratio of the distance from the first position to one end of the beam structure to the length of the beam structure is within the range of 0.3-0.95.
