The present disclosure provides multi-functional sound producing apparatus, including housing defining receiving cavity and sound producing device. The sound producing device includes vibration system and magnetic circuit unit driving vibration system to vibrate along first direction. The magnetic circuit unit includes main magnet assembly and auxiliary magnet. The apparatus further includes motor device which includes elastic member fixedly connected to housing, weight connected to elastic member, magnet component fixed to weight and vibrating along second direction with weight, and driving member fixed to bottom wall to drive magnet component to vibrate. Two groups of magnet component and driving member are provided, each of two opposite sides of main magnet assembly is provided with one group of magnet component and driving member, and second direction is perpendicular to first direction. The present disclosure has advantages of simple assembly, more saved overall space, low costs.

Multi-functional sound producing apparatus

A method includes: obtaining a refresh request of an application, where the refresh request is used to instruct to refresh display data of the application; transferring the refresh request to a display daemon by using a render thread of the application; when communication duration between the render thread and the display daemon is greater than a first time threshold, determining that an exception occurs in the render thread; and when duration in which the display daemon processes the refresh request is greater than a second time threshold, determining that an exception occurs in the display daemon.

Method for processing refresh and display exceptions, and terminal
