Embodiment 1

[0028] figure 1 It is a flow chart of the method in Embodiment 1 of the present invention, such as figure 1 As shown, the method includes the following main steps:

[0029] S1. The motherboard under test selects an audio file and plays it, and outputs two audio signals.

[0030] S2. The main board under test outputs a switching signal to select one audio signal as a microphone input signal and input it into the microphone circuit, and the microphone circuit performs audio collection on it.

[0031] S3. Comparing the audio signal collected by the microphone circuit with the corresponding reference signal.

[0032] S4. Output the test result according to the information obtained from the comparison.

[0033] In the above step S1, the audio file selected by the main board under test may be an audio file pre-stored by itself.

[0034] In the above step S2, the logic of selecting the audio signal is as follows: after the test result of one selected audio signal is obtained, if ...

Embodiment 2

[0036] figure 2 It is a schematic diagram of the device structure in Embodiment 2 of the present invention, such as figure 2 As shown, the device described in this embodiment includes: an audio output comparison module, an audio selection module and a test result output module.

[0037] Among them, the audio output comparison module is used to control the main board under test to output two audio signals and switch signals, and compare the audio signal collected by the microphone circuit with the corresponding reference signal.

[0038] The audio selection module is used to receive two audio signals and switch signals output by the main board under test, and through the selection of the switch signals, the selected audio signal is input into the microphone circuit as a microphone input signal for audio collection.

[0039] The test result output module outputs the test result according to the information obtained by the comparison of the audio output comparison module.

Embodiment 3

[0042] Based on the above embodiments 1 and 2, in specific implementation, the audio selection module can be completed by hardware; the audio output comparison module, test result output module and main control program module can be completed by software.

[0043] image 3 It is a schematic diagram of the specific implementation in Embodiment 3 of the present invention, such as image 3 As shown, the hardware part can specifically be a functional test fixture 31 , which includes two linear attenuation circuits 311 and 312 and a dual selection switch 313 . The signals are speaker signal, receiver signal, motor signal and microphone input signal. The speaker and the receiver of the mainboard under test respectively output fixed-frequency audio signals, which are attenuated by the linear attenuation circuits 311 and 312 and then input to the two input terminals of the dual-way selector switch 313 . The two-way selector switch 313 receives the motor signal and is controlled by the...

Abstract

The invention discloses a method and a device for testing an audio loop of a communication terminal, relates to the field of communication, and aims to solve the problem that the prior art cannot test the audio loop of the communication terminal with a relatively low cost, high quality and high efficiency. The method comprises the following steps that: a tested motherboard outputs two routes of audio signals; the tested motherboard outputs a switching signal to select a route of audio signal as a Mac input signal which is input to a Mac circuit to perform audio acquisition; the audio signal acquired by the Mac circuit is compared with a corresponding reference signal; and a test result is output according to the information obtained according to the comparison. The device comprises an audio output comparison module, an audio selecting module and a test result output module. The method and the device can test the audio loop of the communication terminal under the condition of not being interfered by environment.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for testing the audio circuit of a communication terminal. Background technique [0002] At present, no matter how high the degree of automation and how powerful the functions are, the production and testing audio loop modes commonly used in the field of international communication terminal products still rely on the sensors on the test system to collect the test parameters of the object under test, and then convert them by the computer. Analyze, and finally compare the analysis result with the standard result and output the final test judgment result ("qualified" or "failed"). [0003] Enterprises that conduct quality testing of communication terminal products not only need testing equipment to collect various quality parameters of products, but also need data analysis systems to evaluate the final quality. At present, most of the test equipment in China are import...
