The amplitude reduction amount answered.
In the present embodiment, it can be directed to each resonant frequency, from the original of playing time of the test signal belonging to resonant frequency
Beginning volume starts, and staged reduces volume of the test signal under playing time, until detecting that audio-frequence player device is resonating
Oscillation Amplitude in frequency meets Oscillation Amplitude tolerance condition；Oscillation Amplitude is met to volume decrease when Oscillation Amplitude tolerance condition
Low amounts, as the corresponding amplitude reduction amount of resonant frequency.
Wherein, it can determine that the corresponding amplitude reduction amount of each resonant frequency according to for amplitude tolerance condition, vibrate
Amplitude tolerance condition can flexibly be set according to actual needs.For example, can be resonated according to human ear to audio-frequence player device
When the Bearing degree of abnormal sound that generates, by the difference of the Oscillation Amplitude detected on resonant frequency and the actual margin of audio signal
Value is no more than preset threshold as Oscillation Amplitude and tolerates condition.The reality of the Oscillation Amplitude and audio signal that are detected on resonant frequency
The difference of border amplitude can symbolize Oscillation Amplitude amplification caused by resonance, can also embody resonance and play to audio signal
The influence degree of generation.Therefore, the side of the volume of the playing time of resonant frequency in signal can be tested by stepwise adjusting
Formula or other means, to reduce Oscillation Amplitude amplification caused by resonance, reduces resonance to audio signal to reduce the difference
Play the influence degree generated.
Mode due to reducing the range value of volume or other reduction audio signals on resonant frequency all may be to audio
The influence of the sound quality of signal, therefore, amplitude reduction amount, which can be set in, meets Oscillation Amplitude tolerance condition just, without setting
It is too big, cause serious influence to avoid the sound quality on audio signal.
