Abstract

The invention provides a real-time audio calibration method. A real-time audio calibration program is performed on a third-generation (3G) handheld mobile device by utilizing an electronic device and a testing instrument. In the whole process of the audio calibration program, audio parameters are written into a memory by utilizing a central microprocessor, and are directly read by an audio processor to perform an audio test, so that the testing instrument and the 3G handheld mobile device are connected without being restarted and re-executing communication to further increase the speed of the audio calibration program.

Description

technical field [0001] The invention relates to a real-time audio calibration method, in particular to a method for performing audio calibration without restarting a mobile device. Background technique [0002] With Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system, a Wideband Code Division Multiple Access (WCDMA) system and Code Division Multiple Access 2000 (Code Division Multiple Access 2000; CDMA2000) system and other 3G wireless communication technologies continue to develop and become more mature. Therefore, users of 3G mobile communication systems are also increasing. Correspondingly, the production of 3G handheld mobile devices is also increasing. . [0003] However, during the production process of the 3G handheld mobile device, various calibrations must be performed, including antenna calibration, radio frequency calibration and audio calibration. Among them, the operation procedure of audio calibration is the most inconvenient, resulting ...
