[0030] This embodiment provides a noise reduction method for household appliances, figure 1 Is the flow chart of the method, such as figure 1 As shown, the method includes the following processing:

[0031] Step 101: Obtain the first noise signal collected by the first sound collecting device arranged at the internal noise source of the household electrical appliance and the second noise collected by the second sound collecting device arranged on the household electrical appliance away from the internal noise source of the household electrical appliance signal;

[0032] The household appliances involved in this embodiment include, but are not limited to, refrigerators, air conditioners, and washing machines in smart homes.

[0033] In this step 101, the first noise signal may be collected by a first sound collecting device arranged inside the household appliance close to the noise source inside the household appliance, and the second noise signal may be collected by a second sound co...

no. 2 example

[0048] This embodiment provides a noise reduction method for household appliances, which is roughly the same as the method provided in the first embodiment above, except that the method provided in this embodiment can generate a desired noise signal based on the collected noise signal , Used to replace the expected noise signal stored in home appliances.

[0049] image 3 It is a schematic diagram of generating a desired noise signal in the noise reduction method for household appliances in the second embodiment of the present invention, such as image 3 The method provided by the illustrated embodiment includes the above steps 101 to 104. On this basis, generating a noise cancellation signal according to the obtained first desired noise signal may specifically include: extracting the characteristics of the first desired noise signal, and judging the first desired noise signal Whether the characteristics of the noise signal are consistent with the characteristics of the second des...

Abstract

The invention provides a noise reduction method and apparatus for a household appliance, aiming at poor effects of suppressing noise of household appliances in the prior art. The method herein includes the following steps: acquiring a first noise signal which is acquired by a first voice acquiring apparatus which is disposed at a noise origin inside a household appliance and a second noise signal which is acquired by a second voice acquiring apparatus which is disposed on the household appliance and distant from the noise origin inside the household appliance; based on the correlation between the first noise signal and the second noise signal, removing the effects on the first noise signal by ambient noise signals, acquiring a first expected noise signal of the household appliance; based on the first expected noise signal, generating a noise offsetting signal; and outputting the noise offsetting signal. The technical solution can accurately offset internal noise of the household appliance.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a method and device for reducing noise of household electrical appliances. Background technique [0002] With the continuous development of smart homes and the continuous improvement of people’s living standards, smart homes have gradually entered people’s lives, such as smart refrigerators, smart washing machines, and smart air conditioners. However, these home appliances will make a lot of noise during use. , Such as compressors of refrigerators and air conditioners, motors of washing machines, etc. will make a lot of noise during work, which will seriously affect people’s quality of life. With the rapid development of artificial intelligence, people’s requirements for various home appliances will follow. Therefore, suppression or elimination of various noises generated by home appliances is a very important issue. [0003] At present, there is a solution in the prior art: the s...
