Abstract

The invention provides a switching method of internal and external microphone signals. The switching method of the internal and the external microphone signals comprises the following steps: detecting whether an object is inserted in an earphone socket; switching to an external microphone channel when the object is detected to be inserted in the earphone socket; sampling a recording of the external microphone channel; comparing whether the recording of the external microphone channel is greater than a preset recording value; keeping using the external microphone when the recording of the external microphone channel is greater than the preset recording value; switching to the internal microphone when the recording of the external microphone channel is not greater than the preset recording value. The switching method of the internal and external microphone signals is applicable to an electronic device without the microphone insertion detection. The external microphone is automatically identified and used by utilizing the recording of the external microphone channel, accordingly providing convenience for the user application.

Description

【Technical field】 [0001] The invention relates to a method for switching signals of internal and external microphones, in particular to a method for switching signals of internal and external microphones which is convenient to use. 【Background technique】 [0002] Headsets play a very important role in computer peripherals. Games, music, video, it's everywhere. In Internet cafes, offices and other occasions, earphones are a must-have for computer users. [0003] Common electronic devices such as PDAs or tablet computers support the function of listening to music through earphones, so they all have interrupt terminals for detecting earphones. Now the requirements of users are getting higher and higher. They hope that not only headphones can be plugged into the headphone jack, but they also want to record or sing after the headset is plugged into the headphone jack. For example, Mainland China Patent Application No. 200510100133.7 discloses a method for switching between int...
