Step 203, according to the input voltage, determine impedance value of the electroacoustic monomer at different frequency value.
Specifically, step 203 includes：
Obtain the line impedance R1 between the audio output element and the electroacoustic monomer；
According to the input voltage U1, the line impedance R1 and formula R=U1*R1/ (U-U1), the electroacoustic is determined

In the embodiment of the present invention, after judging resonance frequency point, the intrinsic coefficient of cavity is further determined that, and
Judge whether intrinsic coefficient is more than predetermined threshold value so that more accurate for the detection of cavity leakproofness.
Wherein, above-mentioned intrinsic coefficient can be according to resonance frequency point F0 and formula Q=(ZF0-ZX)/(F0-X) it obtains.Wherein,
ZF0Indicate that impedance value of the electroacoustic monomer at the resonance frequency point, X indicate preset reference frequency point, such as 200Hz, ZXIt indicates
