Such as, described language play back system 14 arranges described first and presets ambient noise value when being 80db, then when described broadcast sound volume acquisition module 142 identify described rising tone voice frequency value reach 80db time, then think that noise has reached this higher limit 80db in air-conditioner 100 current operating environment, then described broadcast sound volume acquisition module 142 directly exits clearance mode, again adjusts the air supply pattern of described air-conditioner; Such as, the gap air supply pattern of described air-conditioner 100 is adjusted back lasting air supply pattern again.
Or, when described language play back system 14 arranges the described second default ambient noise value 35db, then when described broadcast sound volume acquisition module 142 identify described rising tone voice frequency value reach 35db time, then think that air-conditioner 100 current operating environment is quieter, the running noise that when described air-conditioner 100 is blown, self running produces has been not enough to affect the broadcast sound volume of described voice messaging playing module 143, then described broadcast sound volume acquisition module 142 directly exits clearance mode, again adjusts the air supply pattern of described air-conditioner; Such as, the gap air supply pattern of described air-conditioner 100 is adjusted back lasting air supply pattern again.
Further, in language play back system embodiment of the present invention, described language play back system 14 arranges the 3rd and presets ambient noise value, the noise lower limit that namely ambient noise value is corresponding; Described noise frequency acquisition module 141 gets described rising tone voice frequency value and is greater than the 3rd default ambient noise value, then reduce the wind speed of described air-conditioner 100 air-supply; While wind speed blown by the described air-conditioner 100 of reduction, described noise frequency acquisition module 141 gathers and obtains described rising tone voice frequency value, until when described rising tone voice frequency value presets ambient noise value lower than the 3rd, stop the wind speed reducing the air-supply of described air-conditioner 100.Obtain corresponding described broadcast sound volume value by described broadcast sound volume acquisition module 142 according to described rising tone voice frequency value, thus by described voice messaging playing module 143 according to described broadcast sound volume value, play corresponding audio-frequency information.
If described noise frequency acquisition module 141 controls the wind speed of described air-conditioner 100 air-supply when being reduced to default wind speed threshold value, the described rising tone voice frequency value that described noise frequency acquisition module 141 obtains presets ambient noise value lower than the described 3rd not yet, then described noise frequency acquisition module 141 stops the wind speed reducing the air-supply of described air-conditioner; This kind of situation represents that the ambient noise residing for described air-conditioner 100 is larger, then described noise frequency acquisition module 141 is without the need to carrying out clearance measurement noise figure again, namely adjust the air supply pattern of described air-conditioner 100, the interval air supply pattern of described air-conditioner 100 is adjusted to lasting air supply pattern.
The embodiment of the present invention, by the air supply pattern of ambient noise conditions adjustment air-conditioner, improves the accuracy that sound frequency value corresponding to ambient noise obtains, does not also affect the normal use of air-conditioner simultaneously.
