Sony Headphones with Neodymium Permanent Magnets 20160919

Sony Headphones with Neodymium Permanent Magnets 20160919
Sony’s new high-end headphones: MDR-Z1R

Sony prepares to launch the signature series MDR-Z1R headphones with a $2300 price tag to celebrating its 70th anniversary. Once the news was released, the people who interested in sound and music paid much attention to this production, they are pretty curious about the distinction for its high price.

According to the introduction, there’s a 70mm magnesium dome driver that is the core components of the headphones to decide the tone quality partly. And the aluminum-coated diaphragm makes the headphones seems aesthetic and exquisite. Moreover, there are neodymium magnets , the high performance and strongest rare earth permanent magnet , inside the headphones to bring fantastic experience when listen to the music for the better the neodymium permanent magnets are, the better of tone quality as we all know. In addition, the headband is made of titanium and the jack is gold-plated. In a word, the precise internal design makes the frequency response of the headphones up to 120 KHz, which is amazing and impressing for such a high number.

Therefore, from these materials and specifications, we can found that Sony is trying the best to produce a high-end headphone. To meet the expectation of audiophiles, the headphones will be available in the market in November.


Besides, there is another product of Sony that will be launched in November, named Xperia wireless headphone. Users can use the Bluetooth of smart phone to control it to listen to the weather, time, or the latest news. It also can make voice-prompted navigation when driving or walking. However, the price is not fixed yet.

Permanent Magnetic Subway 20160914

Permanent Magnetic Subway 20160914
Magnet Manufacturer China Rare Earth Magnet Limited

According to the reporter, the officials of Changsha railway declared that the first permanent magnet  subway being reviewed and approved the exam smoothly, and now has worked on NO.1 line of Changsha metro.

The asynchronous traction system is always used in the traditional subway installs, while the new type subway was adopted the permanent magnetic traction system. As we all know, the traction system is the core of the whole subway, which is to achieve power-driven. It is said that the quality of the traction system decide the performance of the power, energy consumption and controlling force. Refer to the statistic, the whole subway system should consume more than 3 billion kilowatt of electric per year. Compared with the old one, the permanent magnetic subway can save about 4 millions kilowatt electric, it is about RMB 3 million. What’s more, permanent magnetic with high regenerative efficiency can retroact more electric to the electric network. As a matter of fact, the energy consumption can reduce 11.5 percent in total. With the advantages of high efficiency, low noise and energy-saving, the experts approved to the production and operation of the permanent magnetic traction system consistently. And this action means that our technology of permanent magnetic traction has applied to the commercial field successfully and developed a new way of the railway.

In recent years, with the policy of transportation construction and development introduced constantly, it is the best time to vigorously develop railway transportation. Between 2016 and 2018, there will be more than one hundred programs of railway, and if all of these railways use the permanent magnet traction system, the economic benefits will be enormous.

China is the few of nation in the world that master the technology of permanent magnetic traction system and applied this technology to urban rail and high speed rail area. Therefore, we should take this opportunity and accelerate development positively.

AlNiCo & Neodymium & Ferrite Magnets Applied to Acoustics 20160912

AlNiCo & Neodymium & Ferrite Magnets Applied to Acoustics 20160912
Permanent Magnets Manufacturer China Rare Earth Magnet Limited

1、Magnetic acoustics guitar pickup
The alnico permanent magnet  was wrapped by wires in the pickup, which put under the string of the guitar. Then after power on, the magnetic acoustics pickup interpreting the vibrations of the guitar strings into electrical signals. Actually, a great magnetic acoustics can make your guitar sounds great indeed.

2、Magnetic acoustics door seals
The magnetic acoustic is an anodised aluminum holder. The magnetic acoustics door seals can make the gap between the door jambs being tighten. It can also be used as a stop. What’s more, the most attractive point of the acoustic door seal is to reduce the noise.

3、Magnetic loudspeaker


As we all know, there are permanent magnets in the loudspeaker, which to produce magnetic field in the magnetic gap. And when power on, the electric current through the voice coil and effect by the magnetic field, therefore to produce sound. The magnets of magnetic loudspeaker are always ferrite magnets  and neodymium magnets . The ferrite ring magnets often used in common loudspeaker, and the NdFeB magnets often used in high-end loudspeaker.

Permanent Magnet Manufacturer China Rare Earth Magnet Limited

The Internet developed rapidly and related to other field more and more close these days, especially in the rare earth magnet  industry. The rare earth resource which regarded as no connection with daily life now combined with the Internet and become a new investigation.

Yiyun science and technology cooperation, the dominant cloud computing service provider, recently bided the cloud computing program of Rare Earth successfully. Yiyun will provide reliable, high-performance and extensible cloud computing platform for rare earth. Besides, Yiyun will also provide cloud infrastructure platform, cloud enterprise services platform, cloud industrial index platform, file management systems, backup systems, information security services, network services, data center access and service programs such as operation and maintenance services. And with technical support of Yiyun, future data application of Rare Earth high-tech zone will establish a good foundation for the development of the system, and through sectoral business data flows to achieve end-to-end data integration. And science and application technology of large data and analysis methods will achieve internal and external data, historical data and real-time data integration and intelligent application.

In this year, the Ministry and other relevant government departments introduced massive files to encourage and support domestic enterprises to develop processing technology and recycling utilization. As long as the rare earth enterprises actively participate in the "Internet +" development and extensively use the cloud computing data, they can promote the development of innovative model of rare earths.

Nowadays, the rare earth is not only a product like rare earth permanent magnet , but also a invested goods like gold and stocks. This can be regard as another reform and opening-up. To create opportunities with large data platform, which bring great opportunities to domestic rare earth industry.

Permanent Magnet Inspection Device for Runway of Air Force Airport 20160906

Permanent Magnet Inspection Device for Runway of Air Force Airport 20160906
China Rare Earth Magnet Limited Manufactures Neodymium Permanent Magnet for Military Application

When the plane is gliding, there are must no debris and odds in the runways. The soldiers always have to examine and clear the runways by walks in the intervals of flying. To make the work become more efficiency, the security departments of air force airport has studied an inspection device of individual soldier, which shorten the clear time of two-thirds.

According to the introduction, the biggest hidden dangers of the plane are the debris bung up the engine or puncture the tires of the plane, which also become a worldwide trouble. To solve the problem, the security departments experiment for almost hundreds times and studied the inspection device eventually refer to the principle of vacuuming and the magnetism of permanent magnets. The inspection device was consists of the system of vacuum clearer and neodymium magnets . It can travel 25km for charging a time and the speed is 20 km per hour. About 10 mm diameter stone and the bolts about the size of a finger can be attracted by it easily, which improve working efficiency obviously.




In a military airport of Huabei area, the minister demonstrates the permanent magnet  inspection device personally with his support detachment and it attracts the debris successfully. At present, the inspection device has been promoted and used in most air force airport.
