Abstract

The invention relates to the technical field of kitchen appliances, in particular to a noise reduction method, a noise reduction device and a range hood thereof. The noise reduction method comprises the following steps: 1, collecting a sample; 2, judging whether the noise intensity reaches the standard or not, and repeating the operation of the first step if the noise intensity reaches the standard; thirdly, when the noise exceeds the standard, vibration of the target equipment is restrained through the piezoelectric effect according to the vibration information detected in the first step, and the noise intensity is reduced; meanwhile, audio injection is carried out, and noise made by the target equipment is reconciled; and 4, repeating the step 1 until the noise reaches the standard. The noise reduction device is based on the noise reduction method. The range hood at least comprises the noise reduction device. The piezoelectric actuator is used for suppressing deformation generated by vibration according to the vibration condition of the noise generation part, noise is reduced from the source of noise generation, in addition, noise which is not completely eliminated is improved in cooperation with regulation and control sound, and the auditory experience of a user is greatly improved.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a noise reduction method, a noise reduction device and a range hood thereof. Background technique [0002] The noise characteristic of the range hood is one of the important symbols to measure the quality of the range hood. The operating noise of the range hood not only affects the surrounding environment, but also has a great impact on people's physical and mental health and work. On the one hand, general sound insulation and vibration isolation technologies are widely used, but the noise still cannot be effectively controlled. At the same time, as the future structure is gradually improved towards lightweight, traditional materials have great limitations. With the emergence of new smart materials, their unique properties can be widely used in shock and noise reduction technology. On the other hand, people are increasingly pursuing the humanized functions of range ho...
