Abstract

Embodiments of the invention disclose a method and a device for testing an audio output unit. The method comprises the following steps: making an audio output unit in a mobile terminal play a preset audio signal and making an audio input unit in the mobile terminal record the played audio signal; processing the recorded audio signal to obtain the spectrum information of the recorded audio signal; and carrying out matching for the spectrum information to obtain the spectrum level to which the spectrum information belongs and taking the spectrum level as the spectrum level of the audio output unit. The method needs no manual intervention, and is manpower-saving. The efficiency of audio equipment test is improved effectively, and the test result is not affected by the interference of subjective judgment. The evaluation result is accurate, and the reliability is high.

Description

technical field [0001] The invention relates to the field of audio output unit detection, in particular to a method and device for testing an audio output unit. Background technique [0002] With the popularity of smart phones, it is becoming more and more popular to use smart phones to listen to music. When using smartphones to listen to music, the requirements for sound quality are also getting higher and higher. The quality of the audio output device of the mobile phone has a strong impact on the sound quality, so the audio output device of the mobile phone needs to be tested accordingly to ensure the quality of the audio output device of the mobile phone. [0003] At present, the general audio equipment testing method for sound quality is to record the sound for a period of time and save it as an audio file, then play the audio file, and use manual evaluation of the output audio to complete the audio equipment sound quality test. However, this testing method for audio ...
