First, the product standards should be and the relevant international standards. Measurement of the current speaker in accordance with International Electrotechnical Commission (IEC) of the IEC60268-5: 2003Ed.3.0 revised version. My microphone is a standard developed 90s of last century, measurement reference to the IEC standards, common technical terms refer to the Japanese Industrial Standard JISC5502, these two national standards have been implemented in our country for 15 years. Microphone measurement IEC60268-4: 2004Ed.3 version announced new changes to the development of national standards microphone will be done. At the same time communication with the new language standard microphone and headset (IEC) has published version. In order to promote the further development of electro-acoustic devices, better to electro-acoustic products to the international market, the electro-acoustic products, Revision of national standards is very important. Applied research class project: enterprises should care about multi-channel audio systems Multi-channel sound system and mechanism of electro-acoustic products Currently home to the multi-channel audio trends, such as Dolby 5.1 is the left and right main speakers, center speaker, surround speakers, and after about subwoofer composition. Signal processing and has mature patented technology. In a limited space, multi-channel acoustic source generated by cross-transmission should be placed on the requested speaker and the listener has the best location, and sound system the size of each channel of sound pressure, frequency range, direction and other electro-acoustics listen to the physical characteristics of acoustic, psychoacoustic characteristics will impact on the subjective feelings. Research in this area is now carried out in the relevant departments, but there are a number of basic theory can be discussed. How to make the speaker system to adapt to meet this requirement will be the electro-acoustic devices business concern. Digital electro-acoustic devices and audio equipment, digital audio devices and electro-acoustic device is connected with system The sound system, although each link has to do well, but there will be no inappropriate connection between with the best results. The signal source in the sound system (including microphone, DVD, CD, etc.) and the interface between preamplifier, power amplifier and speaker system interface should be a different concept, in the era of analog devices has been a reasonable solution, to obtain a good sound. Digital pre-amplifier, digital power amplifier, digital microphone, the application of digital speakers, we bring a digital device and digital audio devices, analog devices and digital audio equipment, digital devices and analog audio equipment, how to achieve the most reasonable scientific convergence issues remain to be us to study, so that digital audio equipment, acoustic devices and the performance of the best play. Industry categories of projects: high-fidelity digital audio devices to promote the development of a new generation of power Novel micro-electro-acoustic devices and the establishment of industrial research Communications industries to micro-electro-acoustic devices for research and development that a new direction, but also to electro-acoustic devices supporting tremendous opportunities. Large amount of micro-electro-acoustic devices require consistent. To ensure the matching requirement must be parts of the processing and assembly process to do the work, arranging the scientific process, with advanced processing equipment components, the establishment of semi-automatic assembly line, set parts, product performance testing equipment. Micro-electro-acoustic devices do a reasonable production process, improve efficiency of production, product quality control, consistency is assured, the real communication equipment to meet matching requirements. Principle of micro-electro-acoustic device structure different parts machining requirements, process also vary. Principle structure must be different electro-acoustic devices to establish a dedicated industrial equipment, to make it a real effect. To promote a new generation of high fidelity digital audio device electrical grade Hi-Fi and digital audio devices on the electrical performance and consistency of requests, while also supporting the corresponding electro-acoustic devices to provide the market. Meet the matching requirements, novel, sophisticated technology for professional speakers and home speakers industrial base was established to improve the quality of the speaker system, an important measure.
