Electro-acoustic Association Secretary-General Wangrunli
Electro-acoustic devices mainly refers to speakers, speaker systems, microphones, headphones, headsets, receiver, transmitter, receiver group sent all kinds of communication, such as hats and pickups, as well as accessories.
Electro-acoustic devices are the voice of the people by means of information and communication arts and culture essential components. It is the acceptance of voice, conversion, transmission, playback and measurement capabilities. On the various aspects of human life have a great role.
So far, the electro-acoustic devices specializing in the production of more than 1,000 enterprises, and about a research institute - China Electronics Technology Group television electro-acoustic Institute. Electro-acoustic devices in the production of enterprises accounted for the majority of speakers manufacturers, small part of a more comprehensive types of manufacturers, speakers, microphones, headphones, send it, receiver, communication apparatus, pick up sound, etc. (including the annex). Some of the large backbone enterprises in addition to the above products production, but also the production sound transmission and sound processing equipment, complete sets of sound system equipment.
20th century by the late 1980s, China's electronics industry development strategy, to electro-acoustic devices built electronic components industry in the first export-oriented industries. Currently, China's electro-acoustic devices have been exported to over 100 countries and regions, the United States has become China's export of electro-acoustic devices largest market, many famous international electro-acoustic equipment, audio and video products manufacturers (including president and general manager) have here, and many of our electro-acoustic enterprises formed long-term cooperation partnership.
First, the development of history
1932 Shanghai Asian radio companies imported horseshoe magnet assembly Reed speakers beginning of the electro-acoustic products manufacturing industry in China beginning of the subsequent establishment of a number of small hand-factory workshop or serving as the plant, it was not until 1949, just Reed capable of producing a small amount of excitation and dynamic speakers.
After new China was founded, electro-acoustic devices industry has undergone several stages of development:
  1949 a 1957, is developing products to gradually form electro-acoustic products professional industrial production stage.
On the one hand, a public-private partnership, the plant formed a number of key points combined local state-owned enterprises, such as electrical plants Lee Wen (Shanghai Feilegubin Limited predecessor), the United States really Tianjin Motor Factory (Tianjin beauty electro-acoustic equipment company was), the Guangzhou-broadcasting equipment plant (Guangzhou Guoguang Electric Co., Ltd. predecessor), Shanghai Telecommunications Equipment Factory, etc. On the other hand, Nanjing radio factory, a joint radio equipment factory in North China, such as state-owned enterprises were also established specialized production workshop or factory, and the formation of the electro-acoustic Nanjing Ltd. and Beijing 797 factory. At that time, North China Radio Equipment Plant of a branch (now 797 factories) from the former Democratic Republic of Germany is set to introduce the speakers and microphone product technology, manufacturing technology, and from parts manufacturing to the finished product assembly and testing all the equipment and management systems, This is our industry into the modern electro-acoustic production milestone. 1953, No. 734 state-owned factories set up a communications device designed electro-acoustic group, and explore the use of instruments to measure the delivery, the receiver performance. 1955 to the former Soviet Union experts, electro-acoustic devices for communications laid the foundation for the development.
1958 January 1 1980 is the technology matures, specialized production growth phase.
This first phase used loudspeakers to the radio mainly, and then to black-and-white television sets, for the upsurge in supporting Audio player, speakers have great development, and formed a 400 φ φ55 a more complete series of products to meet the needs at that time supporting, and some factories began to Hong Kong, Southeast Asia exports. 1959 National Day for the 10th anniversary of the 10 capital construction support, our indoor and outdoor PA system sets the beginning of the electro-acoustic technology is a progress. February 1960 television electro-acoustic Institute (3) lead. The task is broadcast by the electro-acoustic devices and electro-acoustic communication devices and three machine (radios, televisions, tape recorders, etc.) study. Three since the establishment of Electro-acoustic device for exploring the theory, design and measurement technology, the development of new electro-acoustic transducer device for a lot of scientific research. The Electro-acoustic owned by the national professional and technical publications "electro-acoustic technology" Series. Three for the establishment of China's scientific research electro-acoustic devices laid a solid foundation. 1966 - 1970, the Department of focusing their efforts on the electronic military power acoustic device development, the rapid expansion of production of electro-acoustic communication devices batch plants, electricity makes sound device in the military during this period has focused on the development. 1974 for the development of China's performances set of music PA system, indicating that China's professional audio products start at the same time, 797 plants, electro-acoustic equipment factory in Nanjing, Shanghai-Electro-acoustic Music Factory, Tianjin plant for the electro-acoustic equipment Sri Lanka 37 countries and the countries of the region Theatre, the parliament building, a stadium field, and so provide the corresponding electro-acoustic devices and assemblies, as well as large domestic Loutangguansuo offer packages of audio systems.
  1981 January 1 1988, matching speakers and a color TV exports with a focus on the development stage.
From the late 1970s, China began its open-door policy has aroused nationwide enterprises have introduced products, technology and production lines. In the early 1980s, the introduction of 797 plants of the Japanese company's former Matsushita membrane capacitance electret microphone technology and production lines, wind and thunder Shanghai Broadcasting Equipment Factory, Shandong Weifang OPTO Electronics Co., Ltd., have been introduced in Japan in a capacitor microphone production lines. Moreover, China's production line has speakers from Japan, the United States, France and the Taiwan region, the introduction of more than 20. At the same time, provinces and cities, towns and townships have set up loudspeakers in the production plant. Through the introduction of technologies and parts manufacturing, assembly production lines and the promotion of large-scale production of electro-acoustic technology industry development for the improvement of quality of Harmony. China's speaker, microphone, stereo headphone output soared. 1985 annual breakthrough 100 million, in 1987 loudspeaker output soared to 180 million, and the industrial structure has also begun to specialized production parts transition. Represented by the Jiangsu and Zhejiang around town and township enterprises, collective enterprises, school-run enterprises has begun to grow, a regional advantage and the Shenzhen Special Economic Zone in Guangdong Province as the representative from all over the various economic sectors formed joint ventures, joint ventures also began to develop , the development of electro-acoustic devices to more than 250.
May 1988 China's electronic components industry associations electro-acoustic set up branches in Beijing.
This will be in May 1988 in Beijing to set up, from the country's 22 provinces, municipalities and autonomous regions, director of the 40 enterprises, managers attended the meeting. Electro-acoustic Association have drawn up a "charter of the association," "Secretariat Rules," "contributions to pay, management methods" and "enhance the concept of industry" norm trip about. Carry out investigations to determine the pulse industry. This will be set up later, commissioned by the government departments, and work according to their own needs, has launched a series of research activities to determine the status of the industry, grasp the pulse of the enterprises for the Government to formulate policies for the Association to provide a basis for work. At the same time, members of the unit to promote the study, exchanges, and promoting a peer solidarity and cooperation between enterprises. Association formulated the "Eighth" and the "Ninth Five-Year" period electro-acoustic devices industrial development policy are as follows: "at different levels, both quantity and quality, engaging characteristics, create famous brands and the scale, fighting exports", "engaging characteristics, create famous brands and the scale fighting exports, as a system, and raising efficiency. "
In 1989, export-led industrial electro-acoustic period of comprehensive development.
Hong Kong and Southeast Asia from the main focus of the market to open up the North American and European markets, and to achieve noticeable results; some key enterprises have entered the international system supporting large companies, as their long-term partner. Parts of this period is specialization, and the electro-acoustic intensive enterprises intensive scale production of mutual promotion and common a period of great development. In the technological transformation is introduced in the 1980s digest assembly speaker on the basis, in accordance with our experience and infrastructure to improve and build more effective and practical production line; a considerable number of parts and components production equipment is also domestic equipment, and only in recent years to introduce some more advanced production technology and equipment spare parts, forming Tin Lok Zhejiang, Ningbo, such as cone Sunningdale Penjia vibration system and specialized components such as large-scale production enterprises, Guangdong Province and Liuzhou, Guangxi, Shanxi Yangquan, and other specialized production plants T Rail. Some of the strength of the old enterprises from the competition and exploration, and gradually make its position, improve their quality and do a good job characteristics, scale, the majority have access to good-cycle. Some new businesses, such as Jiangsu Yuan-yu come to the fore, science and technology as a pilot in the intensive production characteristics and work hard, progress was made into the forefront of industry. 1989 China loudspeaker output reached 210 million, more than Japan output, a first in the world, formed an export-oriented industry.
