The invention discloses an automatic corpus playing device for evaluating call quality of a mobile phone and a test method. The automatic corpus playing device comprises a microprocessor, an mp3 module, an earphone connector, a plurality of API connectors, a lithium battery and a power switch, wherein the microprocessor supports a mobile phone audio interface and supports MIC / GND adaptive detection; the mp3 module is connected with the microprocessor; the mp3 module supports an external TF card; the TF card is used for storing music files in mp3 and amr formats; the earphone connector can be inserted into an earphone jack of a mobile phone to be tested; the mobile phone to be tested is equipped with a test APP; and a plurality of the API interfaces are used for communicating with the testAPP. The automatic corpus playing device of the present invention performs call quality evaluation; the items that can be evaluated are rich, the evaluation accuracy is high, the operation is simple and easy, and the efficiency is high; it is not necessary to build a complicated test environment, as long as the automatic corpus playing device is inserted in the mobile phone; the test APP is open to test; and the test score is automatically given after the test is completed.
Description
technical field [0001] The invention relates to the field of business support and other peripheral support technologies, in particular to an automatic corpus playing device and a testing method for evaluating the quality of a mobile phone call. Background technique [0002] The purpose of the research on corpus playback equipment is to provide a method for testing the quality of mobile phone calls. Specifically, the corpus playback device supports 3.5mm mobile phone audio interface communication. The audio interface should self-adaptively support both OMTP and CTIA earphone standards. The corpus playback device has the function of playing mp3 and has a built-in TF card, which can store a certain amount of music in mp3 and amr formats. document. Its application scenario is that the tester issues playback (test) instructions to the corpus playback device through the mobile phone APP. After the device receives the instruction, it plays the specified music such as mp3 and amr a...
