When the intensity of signal is less than default threshold value, illustrate that the audio signal emitter that user's privileged site is worn is capped or sets
The audio signal emitter that standby ad-hoc location is installed is capped, and now runs according to default second operational factor, or presses
Carry out parameter adjustment according to default second regulation rule.
In the present embodiment, the second operational factor is run and default second regulation rule can be transported with the first operational factor
Capable and default first regulation rule is corresponding, for example: this terminal is air-conditioner, and audio playing apparatus arrange and are worn on people
The ad-hoc location of body (as baby), disappears in the audio signal detecting predeterminated frequency, or the audio frequency detecting predeterminated frequency
When the intensity of signal is less than default threshold value, illustrate that baby is covered with quilt, now this default second operational factor of audio frequency can be
Sleep pattern, such as " 25 DEG C of refrigeration, low wind speed are quiet "；Or, this terminal is electric fan, believes in the audio frequency detecting predeterminated frequency
Number disappear, or detect predeterminated frequency audio signal intensity be less than default threshold value when, the second operational factor can for electricity
The quiet operation of wind speed in fan.
This default second regulation rule is alternatively multiple, is configured by user, for example, is sky detecting this terminal
Adjust device, audio playing apparatus are worn on the ad-hoc location of human body (as baby), disappear in the audio signal detecting predeterminated frequency,
Or detect predeterminated frequency audio signal intensity be less than default threshold value when, illustrate that baby is covered with quilt, adjustable low latitude
Adjust the running temperature of device and/or the operating air velocity heightening air-conditioner, then this default second regulation rule is to turn down air-conditioner fortune
Trip temperature one preset value and/or heighten the operating air velocity of air-conditioner or air-conditioner is carried out sweeping character and conduct make；Or, this terminal is
Electric fan, disappearing in the audio signal detecting predeterminated frequency, or detect the intensity of the audio signal of predeterminated frequency is less than
During default threshold value, then this default second regulation rule is will be one level higher for the wind speed tune of electric fan.
