Referring to fig. 1 and fig. 2, an active noise reduction air conditioner structure provided in an embodiment of the present invention includes: the air conditioner comprises an air conditioner main body 1, a controller 2, a sound collection device 3 and a loudspeaker 4;
the loudspeaker 4 is in communication connection with the controller 2, and the sound collection device 3 is in communication connection with the controller 2; the sound collection device 3 is installed at an air outlet 5 of the air conditioner main body 1, and the sound collection device 3 is used for collecting air outlet sound waves at the air outlet 5 and sending the air outlet sound waves to the controller 2; loudspeaker 4 installs in the air-out region, loudspeaker 4 installs on the air conditioner main part 1 wherein, the air-out region is: when the air conditioner main body 1 works, the intensity of wind noise is not less than a first preset intensity; an included angle between the sound production direction of the loudspeaker 4 and the air outlet direction of the air conditioner main body 1 is smaller than 90 degrees, and the included angle between the air outlet direction of the loudspeaker 4 and the plate surface of the front panel of the air conditioner main body 1 ranges from 10 degrees to 50 degrees; the controller 2 is configured to determine a target sound wave according to the outlet air sound wave, and control the speaker 4 to sound according to the target sound wave, where the target sound wave is: and the intensity of the sound wave obtained after the superposition with the air outlet sound wave is smaller than that of the sound wave with second preset intensity.
The communication connection may be realized by a communication cable or by a wireless network signal, and is not particularly limited herein. The sound collection device 3 may be a microphone, or other devices for collecting sound, and the present application does not specifically limit the specific form of the sound collection device 3.
The sound collection device 3 and the loudspeaker 4 can be clamped and connected through a buckle, connected through screws, bonded by viscous materials, and mounted in the air outlet 5 of the air conditioner main body 1 in a magnetic adsorption mode or in the air outlet 5 of the air conditioner main body 1 in other modes.
The controller 2 may be an existing controller commercially available, or the controller 2 may be programmed by an existing WeChat processor. The controller having the functions of the embodiments of the present invention is the prior art and will not be described in detail herein.
The first preset intensity may be any one of the intensity values of 50 db to 100 db, or other intensity values, and a person skilled in the art may set the specific value of the first preset intensity according to actual conditions, and when the value of the first preset intensity is large, the installation position of the speaker 4 is closer to the air outlet 5 of the air conditioner main body 1, so that the noise reduction effect is better. The first preset strength may be set according to the wind noise strength of the air-conditioning outlet 5, for example, the first preset strength may be 0.4 to 0.8 times of the wind noise strength of the air-conditioning outlet 5, or may be other multiples.
The intensity can be for 44 decibels in the second is predetermine, and the human is in the environment that noise intensity is less than 44 decibels, and experience is good, and of course, the intensity can be the arbitrary value below 44 decibels in the second is predetermine, and it should be explained, the embodiment of the utility model provides an in, the second predetermines intensity also can be for other values, for example 45 decibels, 50 decibels etc. that are greater than 44 decibels, only in actual conditions, is less than 44 decibels, and the human has the experience of preferred.
The included angle between the sound production direction of the loudspeaker 4 and the air outlet direction of the air conditioner main body 1 can be any included angle smaller than 90 degrees. For example, the angle between the sound emission direction of the speaker 4 and the air outlet direction may be 30 ° or 40 °, and for example, the angle between the sound emission direction of the speaker 4 and the air outlet direction may also be 0 °, which is equivalent to that the sound emission direction of the speaker 4 is the same as the air outlet direction. The sound production direction of speaker 4 with the contained angle between the air-out direction of air conditioner main part 1 is less, and the sound wave that speaker 4 sent is easier and the air-out sound wave stack that air outlet 5 produced, consequently, in order to make noise reduction better.
