WIPO Patent Application WO/2023/217111
Kind Code:
A1
Abstract:
The present application relates to the technical field of terminals, and discloses an electronic device, the electronic device comprising a housing, a vibration assembly, and a vibration damping assembly. A mounting cavity is formed in the housing. The vibration assembly and the vibration damping assembly are both disposed in the mounting cavity. A sound generating cavity is formed in the vibration assembly, and the sound generating cavity is in communication with the mounting cavity. The vibration assembly is connected to the housing and generates first vibration in a vibrating state. The vibration damping assembly comprises a piezoelectric module arranged on the housing; when the vibration assembly generates the first vibration, the piezoelectric module performs second vibration, the first vibration being different from the second vibration, and the second vibration being usable for dampening the effect of the first vibration on the housing. In the described electronic device, the effect of vibration generated by the vibration assembly on the housing is weakened by means of the vibration damping assembly, the vibration felt when a user holds the electronic equipment is weakened, and the use experience of the user is improved. The piezoelectric module has a simple structure, facilitating light and thin design of the electronic device.
