Embodiment 2

[0083] Figure 6 Shown is a flow chart of an earphone testing method provided by an embodiment of the present invention, as Figure 6 As shown, the methods described include:

[0084] S601. Detect whether there is an earphone plug inserted.

[0085] In the embodiment of the present invention, in order to further improve the test efficiency of the earphone, the mobile terminal can determine when to start the earphone test. Preferably, the mobile terminal can detect whether there is an earphone plug inserted into the earphone socket. , then start to execute steps S602-S606, if no headphone plug is detected, no detection is performed.

[0086] In another embodiment of the present invention, for ordinary users, the user may also manually input a command to start the test, and the mobile terminal receives the test start command input by the user, and then starts to execute steps S602-S606.

Abstract

The invention relates to an earphone testing method and device. The earphone testing method comprises the steps of sending testing signals to a first sound channel of an earphone through a plug of the earphone; receiving sound sent out by the first channel of the earphone through a microphone of the earphone, and generating a first frequency response curve according to the sound sent out by the first sound channel; sending testing signals to a second sound channel of the earphone through the plug of the earphone; receiving sound sent out by the second sound channel through the microphone of the earphone, and generating a second frequency response curve according to the sound sent out by the second sound channel; judging whether the first sound channel, the second sound channel and the microphone are normal according to the first frequency response curve and the second frequency response curve. The earphone testing method and device can test earphones and microphones without the utilization of professional testing equipment, greatly saves cost, improves production efficiency, saves resources and protects the environment.

Description

technical field [0001] The present invention relates to the technical field of sound playback equipment, in particular to the technical field of earphones, and in particular to an earphone testing method and device. Background technique [0002] Like many production industries, currently headphone manufacturers need to test the headphones that are about to leave the factory when they are using sound field headphones. The test usually requires the use of professional testing equipment to test each channel of the headphones separately. To judge whether each channel of the earphone is normal, usually, the test equipment will send the audio signal for testing to each channel of the earphone, respectively make each channel of the earphone play the audio signal for testing, and then use a sound The acquisition device collects the sound played by each channel of the earphone, and then judges whether each channel is normal based on the collected sound. [0003] Correspondingly, for...
