1. An air leak detection method, used for a cavity, comprising:
inputting, by a signal generator, a scanning signal into the cavity;
recording, by a storage, a response signal of the cavity related to the scanning signal; and
analyzing, by a processor, the response signal for determining whether the cavity is air leaking;
wherein the step of analyzing the response signal for determining whether the cavity is air leaking comprises:
calculating an impedance curve of the cavity according to the response signal; and
comparing an impedance peak value of the impedance curve with a threshold to determine whether the cavity is air leaking.
