In-ear headphone testing system and method

An in-ear headphone testing system, comprising a to-be-tested in-ear headphone, a terminal device, and a testing device, wherein the terminal device is configured to control the to-be-tested in-ear headphone to output a preset sound, and the testing device comprises a base, a sound collection module, a coupling cavity, and a control chip, wherein the control chip is built into the base, the base is connected to the coupling cavity, the sound collection module is placed between the base and the coupling cavity, and the coupling cavity is used for placing the in-ear headphone;

• the sound collection module is configured to collect a sound signal outputted by the in-ear headphone;
• and
• the control chip is configured to process the sound signal to obtain a test result;
• wherein the control chip comprises a data acquisition module configured to save the sound signal collected by the sound collection module to obtain audio data and a data processing module configured to process the audio data to obtain the test result;
• and
• wherein the data processing module is further configured to transform the audio data from a time domain to a frequency domain to obtain original frequency response information, intercept frequency response information of a set bandwidth from the original frequency response information to obtain intermediate frequency response information, smooth the intermediate frequency response information to obtain target frequency response information, and determine the test result according to the target frequency response information.
