Silent black technology! How does ferrite magnet composite bonding material make smart home appliances "as quiet as a cat"?

Every day when you get home from work, you want to enjoy the convenience brought by smart home technology, but you get a headache from all kinds of buzzing sounds? You may not know that many noise problems can actually be solved by a special material - that is, a composite bonded magnet using ferrite magnets.

When it comes to the noise of smart home appliances, it mainly comes from two aspects: one is the mechanical vibration when the motor is running, and the other is the whistling produced when the electromagnetic components are working. Although traditional ferrite magnets can solve some electromagnetic noise, they are powerless against mechanical vibration. The new type of composite bonded magnet, by combining high-performance ferrite magnets with special rubber, has perfectly solved this problem.

The key lies in that it combines the dual advantages of ferrite magnets and rubber. Ferrite magnets have excellent magnetic permeability and stable magnetic performance, and can effectively suppress electromagnetic noise. Rubber materials, on the other hand, absorb mechanical vibrations like "shock absorbers". It‘s like installing both an "electromagnetic silencer" and a "mechanical shock-absorbing pad" on household appliances at the same time.

We specifically tested the sweeping robot using this ferrite magnet composite material. The noise of the ordinary model during operation is about 55 decibels, while the model using new materials has directly dropped to 45 decibels. The most obvious change is that the shrill high-frequency noise of the motor has almost completely disappeared, which is attributed to the optimization effect of ferrite magnets on the electromagnetic field.

- Air purifier: Ferrite magnets effectively reduce the electromagnetic noise of the fan motor

- Smart refrigerator: The shock-absorbing property of composite materials makes the compressor operate more quietly

- Kitchen appliances: The stable performance of ferrite magnets reduces noise caused by electromagnetic interference

It is worth mentioning that modern ferrite magnet technology has developed to a very mature stage, with controllable costs and stable performance. This enables composite bonded magnets to be widely applied in various household appliances. In the future, with the further upgrading of ferrite magnet materials, we may witness quieter and more efficient smart home products.

Purchasing tip: Nowadays, many high-end home appliances on the market have begun to label "adopting ferrite magnet noise reduction technology". When making a purchase, you can pay special attention to this detail. After all, a quiet home environment is often hidden in these invisible technical details.

From a professional perspective, ferrite magnets still have great potential in the field of noise reduction. Researchers are developing a new generation of ferrite composites, which are expected to keep the noise of household appliances at a lower level. Perhaps in the near future, "silent operation" will become a standard feature of smart home appliances, and behind this, the continuous innovation of ferrite magnet technology is indispensable.
