Document Type and Number:
WIPO Patent Application WO/2021/052303
Kind Code:
A1
Abstract:
Embodiments of the present application provide a sound producing device and an electronic equipment. The electronic equipment may comprise mobile or fixed terminals having a speaker function, such as a mobile phone, a tablet computer, a laptop computer, an ultra-mobile personal computer (UMPC), a handheld computer, an interphone, a netbook, a POS machine, a personal digital assistant (PDA), an automobile data recorder, a wearable device, a virtual reality device, Bluetooth speaker/headphones, or a vehicle-mounted front loading. By configuring a damping assembly, the damping assembly achieves a slowing function on an air flow formed in a rear sound cavity, so that the air flow formed in the rear sound cavity enters a cavity inside the electronic equipment at a low flow speed state; in this way, the impact of the air flow on a thin electronic equipment casing is reduced, and the amplitude is reduced, so that the purpose of inhibiting or reducing the casing vibration of the electronic equipment is achieved, and the experience of a user when holding the electronic equipment is improved.
