Technical issues of Shangqiu professional audio sound design is relatively more simple. To the speaker, for example, the basic completion of the design is the low frequency response and divider, it needs a certain amount of theoretical knowledge. Technically speaking, the ideal heavy burst system should be able to fully reproduce the input time-domain waveform. In other words, it is a linear system, and has a flat frequency response and pure delay linear phase shift, but in fact this is impossible. So very particular about the choice of the speaker unit speaker unit manufacturing knowledge. Unit matching the design of the speaker system, it is not only subject to the technical requirements of timbre optimization and best replay it is also subjective auditory and heavy burst content of which ( divider and the design of the crossover point). The of Shangqiu professional audio Tel Jiaming Yang 1503 +71780 +75 QQ2579114209 greatest manufacturer of speaker unit here. There are two main processing unit speaker factories in our country. One long-term adherence to self-development, production, because they know how good unit gold content and high value-added ingredients. Although the largest gains but also the most difficult. Another on an OEM basis and abroad to foreign countries in accordance with their own requirements place an order, the use of the foreign variety of advantages to develop their own products, which can also be regarded as a shortcut. Both methods require proficient unit's intrinsic quality (physical and auditory). I am not in favor of foreign direct purchase of the finished unit. Image (the so-called flagship Some manufacturers do it, this practice has become obsolete), in order to show their strength. Another sales made directly to the speakers in the country. Unfortunately, do not, is still relatively common, and are able to see in the previous exhibition. This shows what happens then? Shangqiu the professional audio Tel Jiaming Yang 1503 +71780 +75 QQ2579114209 speaker system design in addition to the unit, as well as divider and crossover design, the sensitivity of each unit match box the appearance, choice of materials, structures, will not elaborate. Worth mentioning is the technical design is verified by measuring. On the one hand is a mathematical model of the error, on the other hand there is the error caused by the interaction of the various parts of the system. Need to be designed for the correction. Now, most manufacturers test software, and technical point of view the test reports from the sessions of the exhibition to see the problem of low-frequency measurement, curve smoothing order selection problem. From the form and details of the curve, you can see many of the elements of the sound, the sound quality, which is a basic technical issues. Shangqiu the professional audio Tel Jiaming Yang 1503 +71780 +75 QQ2579114209 professional sound system design, engineering staff attention general focused on the engineering specifications and national standards. In fact, there is also the tone control. With the improvement of living standards, cinemas, theaters, concert halls, stadiums and other sound reinforcement timbre should also cause a high degree of attention of designers. Engineering and technical personnel handling timbre relatively speaking relatively simple, as long as he choose good equipment on the line. In addition to speakers, amplifier, mixer, peripherals have an impact on the sound system of the heavy burst. A good design considering engineering design, in addition to architectural acoustics design and the hall with the one hand, the design of the system must be standardized to ensure reliability as well as national standards under the sound field indicators should also consider the tone control problem. Generally only consider the construction side of the investment control and functional requirements. On this basis, the design should be able to accurately foretold the construction side of the final sound field sound effect. In the field of professional audio equipment, counterfeit and shoddy products still flooded the market, how to determine the value of the merchandise from various angles of the performance, reliability, timbre, and still is necessary engineering and technical personnel effort, while domestic professional audio equipment The territory is also much to do!
