The 6th pavilion promoted by the exhibition will mainly focus on lithium new energy exhibits and join forces with the Yichun National Lithium New Energy High-Tech Industrial Base. Apart from leaders of ministries and commissions, academicians in the industry, and more high-level companies such as BYD Co., Ltd. Leaders and other corporate representatives will gather together to interact on the spot, explain the development of the industry, explore industry prophets, and jointly exchange and discuss policies and measures in the national “Twelfth Five-Year Plan†on new energy, new energy vehicles, new materials, and energy conservation and environmental protection; The development of international lithium battery cutting-edge technologies, including lithium-ion battery market development prospects, lithium-ion battery positive/negative materials, lithium-ion battery separators, lithium electronic battery electrolyte development and application, power lithium-ion battery, energy storage lithium-ion battery related Technology and Industrial Development, Lithium Future Technology - Development of Lithium-air Battery, Design and Safety Assessment of Lithium-ion Battery Electric Vehicles, Hybrid Electric Vehicles, Development of Electronic Control Systems for Lithium Ion Battery Packs, Battery Charge and Discharge Technology and Charging Infrastructure Construction and Industrialization and Industry of Lithium New Energy Base construction and so on. As a major event in the lithium battery new energy industry in 2011, it is an opportunity not to be missed by the industry.
BYD Co., Ltd. was founded in 1995 as a Hong Kong-listed high-tech private enterprise. The major products are IT industry and automotive industry, including nickel-cadmium batteries, nickel-metal hydride batteries, lithium batteries, plastics, LCD/LCM, and automobiles. BYD has nine production bases in Guangdong, Beijing, Shanghai, Changsha, Ningbo and Xi’an, with a total area of ​​nearly 10 million square meters. As the largest battery manufacturer in China, BYD has attracted attention and its most important is its battery technology. Wang Chuanfu, chairman of BYD's board of directors, once said that 2020 will be the world of electric vehicles, and BYD has mastered the “iron battery†power of the core technology of electric vehicles.
The battery that affects the development of electric vehicles is the battery, and the core technology of electric vehicles is also the battery. As the largest battery manufacturer in China, whether it is the initial nickel-cadmium, nickel-metal hydride battery field, or the lithium battery field that later entered, BYD stepped in. One area, which is facing the controversy, seems to have become a vicious circle, and facts show that the sharp judgment on the development of the industry also allows doubting shareholders and industry people to regain confidence in it. BYD is engaged in the research and development of electric vehicles and has inherent advantages. It also allows the industry to have more expectation for BYD. Mr. He Long disclosed that it is a leading company to invest in electric vehicles in China and even in the world, especially in the real sense of research and development of electric vehicles. (Editor's Note: Electric vehicles currently seen on the market are basically hybrid vehicles. Basically, oil-based, or mainly based on electricity, and BYD focuses on pure electric vehicles, or electric-based hybrid vehicles), BYD is leading. Car-mounted iron batteries require a high level of product consistency. A 1% battery inside a car can cause 100% defects. This is why the industrial development is slower because of the battery technology. The development of electric vehicles to a certain extent, there will inevitably be how to store the electricity, the battery is not likely to do a storage power station. This is all that needs to be explored, and it may be the next wave of hot spots. He Long pointed out that in order to uphold this concept, BYD Company built a one-megawatt energy storage power station inside the company and used it as a demonstration power station. The efficiency is very high. What kind of message Mr. He will bring to this forum is worth looking forward to. In addition, Hall 6 of this year's exhibition gathered a group of outstanding manufacturers of power batteries for electric vehicles. We would like to welcome you to visit and exchange.
Aviation headphones are used in airplanes, cars, subways, etc., to facilitate passengers to listen to audio and watch videos to enjoy a pleasant journey.
The aviation earphones are mostly disposable, so the structure is extremely simple, the shape is relatively ordinary, the materials are small, and the annual usage is very large. The number of inquiry can reach several million or even tens of millions, so the cost is very cheap. earphones can cost as little as 10-15 cents. Therefore, they are disposed of as garbage after used, and passengers could take it away for personal use.
Styles can be divided into on ear headphones and in ear earphones.
Functional difference: power, impedance, and sensitivity etc. are also different. Airplane Headphone is mainly customized according to the equipment, place and user used. For example, 1 customer might require 300 ohms impedances , and other customers may need 32 ohms. For adults, the sensitivity may reach 100DB or more.To children, the sensitivity may be around 85-90 DB.
In addition, aviation headphones are not all disposable ones. Some first-class cabins need to be equipped with headphones with good noise reduction, sound quality and functions. So the price will be much more expensive.
