The invention discloses an earphone edge sound detection method, an earphone edge sound detection device and an airflow simulation device. A loudspeaker front cavity of the earphone is provided with an air leakage hole, and the method comprises the steps: picking up a corresponding audio signal through a reference microphone disposed outside an earphone structure when an air flow generated by an air flow simulation device is inputted into the earphone through the air leakage hole of the earphone and then flows out of the earphone; performing Fourier transform and discretization processing on the audio signal to obtain a single-frequency spectrum curve; detecting the edge sound of the earphone according to the highest peak of the single-frequency spectrum curve, and judging whether the structural design of the earphone is qualified or not according to a detection result. According to the earphone edge sound detection method, the internal structure of the earphone does not need to be modified, the earphone edge sound detection method is more convenient, the earphone edge sound detection cost is greatly reduced, the earphone edge sound detection efficiency and detection accuracy are improved, and the finally obtained edge sound detection result can be used for guiding the improvement of the internal structure of the earphone.
Description
technical field [0001] The present application relates to the technical field of earphones, in particular to a method and device for edge sound detection of earphones and an airflow simulation device. Background technique [0002] In recent years, TWS (abbreviation for True Wireless Stereo, that is, true wireless stereo) earphones have experienced explosive growth. At the same time, people have higher requirements for the user experience of TWS earphones. In order to effectively balance the air pressure in the speaker cavity, TWS earphones usually solve the problem by opening vent holes in the front cavity of the speaker, but this method is easy to introduce edge sound problems. [0003] Such as figure 1 As shown in FIG. 1 , a schematic diagram of the generation principle of earphone edge sound is provided. When a user wearing a TWS headset is in a windy (airflow) environment, when the airflow passes through a solid edge like a vent hole or passes through the slit where th...
