s1, respectively inputting test electric signals into the main sounding device and the auxiliary sounding device to obtain a first reference point acoustic response of the main sounding device and a second reference point acoustic response of the auxiliary sounding device.

The test electrical signal is an input signal of the intelligent device for reducing leakage sound, and can theoretically use an approved broadband signal, and generally uses common signals such as frequency sweeping, white noise or powder noise.

The reference sound point is the frequency response of the sound generating device and is obtained by measuring through a microphone.

S2, acquiring a first transfer function of the main sound generating device according to the test electric signal and the first reference point acoustic response; and acquiring a second transfer function of the auxiliary sounding device according to the test electric signal and the second reference point acoustic response.

The first transfer function is an inherent property of the acoustic system and is only dependent on the system state, such as relative position, placement, etc., and is not affected by the drive signal.

Specifically, the first transfer function is:

S1＝T1/A；

wherein S1 is the first transfer function, T1 is the first reference point acoustic response, and A is the test electrical signal.

The second transmission signal is similar to the first transmission signal, and will not be described herein.
