Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
According to one aspect of the present invention, a home appliance is presented. According to an embodiment of the present invention, the home appliance includes: a body having thereon a noise source component that generates noise audio; a noise reduction assembly, the magnetostrictive member being adjacent the noise source component and disposed in a path of propagation of noise audio generated by the noise source component, the noise reduction assembly comprising: the alternating magnetic field generating piece is arranged on the body and is suitable for generating an alternating magnetic field; -a magnetostrictive member adapted to generate acoustic waves counteracting said noise tones under the effect of said alternating magnetic field.

Therefore, the household equipment provided by the embodiment of the invention has the active noise reduction function, and can realize self noise reduction, so that the quality of the household equipment is obviously improved.
According to an embodiment of the present invention, the noise source part for generating noise audio frequency provided on the household apparatus is not particularly limited, and any part capable of generating noise may be used. Such as motors, fans, electromagnetic generating parts in induction cookers, soymilk makers, juicers, wall breaking cutters, etc. found in all household appliances. The noise generated by the various noise sources can be reduced or completely eliminated by the noise reduction assembly.
According to a specific embodiment of the present invention, the noise reduction assembly may further include: an audio collector and a controller, wherein the audio collector is adapted to collect the noise audio; the controller is respectively connected with the audio collector and the alternating magnetic field generating piece, and is suitable for analyzing the noise audio collected by the audio collector and sending out an execution instruction to the alternating magnetic field generating piece according to an analysis result. Thus, by providing the audio collector and the controller, the noise reduction assembly can be enabled to perform noise reduction with a target and accuracy. Specifically, the audio collector sends the collected noise audio to the controller, the controller is suitable for analyzing the noise audio collected by the audio collector, for example, measuring the decibels, the frequency wavelength and the like of the noise audio, when the decibels of the noise exceed a preset value, the controller sends an execution instruction to the alternating magnetic field generating part, and meanwhile, the magnetic field of the alternating magnetic field generating part is controlled according to the measured frequency wavelength of the noise, so that the magnetostrictive part can generate sound waves with the same frequency wavelength but opposite phases with the frequency wavelength of the noise under a specific magnetic field, and therefore noise sound waves are accurately and effectively counteracted, and the purpose of noise reduction is achieved. Therefore, the noise reduction assembly is further improved, so that the noise reduction accuracy can be effectively improved, and the noise reduction effect is remarkably improved.
According to an embodiment of the present invention, the above-mentioned audio collector should be disposed adjacent to the noise source part. Such as on the motor, or other assembly components adjacent to the motor, may be positioned in the path of greatest noise transmission, thereby effectively collecting noise and facilitating collection and removal during the first time of noise transmission.
According to an embodiment of the invention, the magnetostrictive member is disposed adjacent to the noise source component and on the path of propagation of the noise audio generated by the noise source component, for example, in the most predominant path of propagation. Therefore, the noise can be effectively eliminated in the noise transmission process, and the purpose of noise reduction is achieved.
According to the embodiment of the invention, the magnetostrictive member and the alternating magnetic field generating member in the noise reduction assembly can be arranged oppositely or in parallel, so that the magnetostrictive member is always positioned in the region of the magnetic field generated by the electromagnetic generating member, the stronger magnetostrictive vibration of the magnetostrictive member is improved, and further, the sound wave of rapid high-frequency vibration generated by the electromagnetic telescopic member can be further improved, so that the noise reduction effect is improved. According to the specific embodiment of the invention, the specific thickness of the magnetostrictive member and the alternating magnetic field generating member can be 0.5-5mm, so that the magnetostrictive member can be positioned in the strongest magnetic field area generated by the alternating magnetic field generating member on the premise that the magnetostrictive member can not touch the alternating magnetic field generating member to influence the frequency, the amplitude and the like of generated sound waves during vibration, and the sensitivity of the magnetostrictive sheet is further improved and the noise reduction effect is improved.

Thus, the applicability of the magnetostrictive noise reduction assembly can be further improved.
According to a specific embodiment of the present invention, the magnetostrictive member is configured as a magnetostrictive sheet, and the magnetostrictive sheet vibrates in a thickness direction under an alternating magnetic field. The magnetostrictive member is constructed into a magnetostrictive sheet, so that the vibratility and the sensitivity of the magnetostrictive sheet can be improved, and further, the magnetostrictive sheet can vibrate rapidly and permanently and generate sound waves capable of counteracting noise, and the noise reduction effect is improved. According to the embodiment of the invention, one end of the magnetostriction piece can be arranged on the body of the household equipment, and the other end is a free end, so that the vibratility of the magnetostriction piece can be further improved, and the noise reduction effect is improved. In addition, the magnetostrictive member is configured as a magnetostrictive sheet, is arranged on a path of noise propagation, and is arranged perpendicular to the path, so that not only can the effect of intercepting noise be achieved, but also the sound wave generated by the magnetostrictive sheet can be identical and opposite to the propagation path of noise cancellation, thereby further improving the purpose of noise cancellation.
According to an embodiment of the present invention, the material forming the magnetostrictive sheet may include: tb (Tb) 0.3 Dy 0.7 Fe 1.95 . The magnetostriction sheet containing the material has the advantages of more sensitive induced magnetic field change, high expansion rate, strong deformation resistance, better fatigue resistance, good stability and long service life. Therefore, sound waves capable of eliminating noise can be generated more stably and permanently, and the noise reduction effect is improved.
According to an embodiment of the invention, the thickness of the magnetostrictive member, such as a magnetostrictive member sheet, is 0.3-3 mm. The thickness of the magnetostrictive sheet is in the range, so that the magnetostrictive sheet has high expansion rate, can timely react through the change of a magnetic field, has strong deformation resistance, better fatigue resistance, good stability and long service life; when the thickness of the magnetostrictive sheet is less than 0.3 mm, the magnetostrictive sheet is easy to deform or damage due to the excessively thin thickness of the magnetostrictive sheet due to long-time vibration, and when the thickness of the magnetostrictive sheet is greater than 3 mm, the magnetostrictive sheet cannot timely make a corresponding telescopic reaction according to the change of a magnetic field due to the excessively thick thickness of the magnetostrictive sheet, and the amplitude of the preset vibration cannot be reached, so that noise reduction sound waves are not generated timely and accurately.
According to an embodiment of the present invention, the frequency of vibration of the magnetostrictive member may be 18 to 100KH, and may be specifically adjusted according to noise so as to achieve an optimal noise reduction effect. Specifically, the inventors found that if the frequency is too low or too high, the frequency of the generated sound wave is affected, and the sound wave cannot coincide with the noise, and the noise reduction effect is not ideal.
According to a specific embodiment of the invention, the power of the alternating magnetic field generating element is 30-300W. Therefore, the alternating magnetic field generated by the alternating magnetic field generating piece can generate vibration opposite to the vibration of the noise source part, so that the vibration of the noise source part is effectively counteracted, and the noise reduction effect is achieved.
According to an embodiment of the present invention, the home appliance may be at least one of a soymilk machine, a stirrer, a juicer, a wall breaking machine, an electric cooker, an induction cooker, an air conditioner, and a washing machine.
