Embodiment approach
[0039] In step S100 of the present invention, an audio effect service component is pre-registered and a communication thread is created. Specifically, the present invention registers an (audio effect service, AE service) audio service component, and create a communication thread to communicate with the AEservice. In the present invention, in order to facilitate better communication between the AE service and the newly created communication thread, the AE service is derived from intentservice , instead of directly deriving from the service class, because if the AE service is directly derived from the service class, the main thread of the application in the mobile terminal will be used by default, thereby reducing the performance of all running activities in the application; however, IntentService is a Service class Subclass, which is mainly used to handle asynchronous requests. The present invention does the following processing by declaring all services in the manifest file of...

The present invention discloses a mobile terminal and an audio-left and right channels automatic switching method of the mobile terminal. The method includes the steps of registering a sound effect service component in advance and creating a communication thread; monitoring a rotation angle of the mobile terminal in real time by using the communication thread, and transmitting data of the monitored rotation angle of the mobile terminal to the sound effect service component in real time; and determining, by the sound effect service component according to the data of the rotation angle of the mobile terminal, whether to switch the audio-left and right channels, wherein when the rotation angle of the mobile terminal is less than or equal to 90 degree, the sound effect service component does not switch the audio-left and right channels, or when the rotation angle of the mobile terminal is greater than 90 degree, the sound effect service component switches the audio-left and right channels. Through adoption of the method, the audio-left and right channels can be switched in real time, so as to ensure that sound field reverse never occurs in the mobile terminal in any placement angle, thereby ensuring best sound audial experience.
Description
technical field [0001] The invention relates to the application field of mobile terminals, in particular to a method for automatically switching left and right audio channels of a mobile terminal and the mobile terminal. Background technique [0002] As society develops faster and faster, Internet technology and the degree of integration with electronic technology are getting higher and higher. The popularity of mobile phones and portable devices is getting higher and higher. Multimedia function is the most used application of consumer electronics equipment users. How to improve user experience and user experience has become a problem that every manufacturer needs to consider. Audio and video is a system design. Many manufacturers are limited to using better devices on the basis of their own products, spending more expensive accessories to improve listening experience and sound quality. However, improving various indicators of audio testing is the back-end Design very compl...
