Document Type and Number:
WIPO Patent Application WO/2022/007050
Kind Code:
A1
Abstract:
Provided are a sound production apparatus and an electronic device having same. The sound production apparatus comprises: a first substrate having a first through hole in the center thereof, a vibration layer arranged above the first substrate, a connecting member located in the first through hole and connected to the vibration layer, and a driving device driving the vibration layer to vibrate, wherein the vibration layer comprises a fixed part positioned above the first substrate and fixed on the first substrate, a vibrating diaphragm suspended above the first through hole, and an elastic connecting member for connecting the vibrating diaphragm and the fixed part; the elastic connecting member comprises a connecting part used for being connected to the vibrating diaphragm, and an elastic part capable of moving in a central axis direction of the vibrating diaphragm, wherein one end of the connecting part is connected to the vibrating diaphragm, the other end of the connecting part is connected to the elastic part, the elastic part is connected to the fixed part, the elastic part is located above the first substrate, and the first substrate is provided with an avoidance groove matching the elastic part. The present application effectively solves the problems of unstable vibration and an insufficient full-frequency domain of a vibrating diaphragm in the prior art.
