Henan line array sound engineering company to undertake large-scale projects need to cover a relatively wide area, single line array sound is usually insufficient to meet the need to be more than just linear stereo audio group to fight synthetic linear array (display), and in the display speaker system HSI can make to the characteristics, the high frequency sound waves line array audio line array sound between rooms without mutual interference, with a pair of speakers above the directional characteristics of the composition of the eight-shaped display, you can cover a single line array sound times, otherwise, sound has interfere with each other in front of professional audio, seriously affect the uniformity of the sound field and sound clarity. Power handling capability of Henan line array speaker system to undertake sound engineering company) speaker power handling capability (or speaker of rated power) is an important technical parameters, which represents the speaker power input capability to withstand long-term safety of continuous work, the speaker system sound speaker the sound directivity characteristics usually 贾明阳 1393 + 90664 + 17 Zheng * City technology market in Milan sun, Building 5, Unit 2, 208 low frequencies (below 200Hz) are non-directional, even the direction of propagation, but in high When the band, showing a strong sound propagation direction, the directional characteristics (all types of linear acoustics are not the same) is what we want to be in the system design application, excellent constant directivity characteristics can be arranged at the scene of the sound waves energy is concentrated in the audience area, to avoid the intense sound waves reflecting surface and Henan line array sound engineering company to undertake the mutual interference of the sound field directivity speaker makes SPL axial deviation angle increases with the sound pressure level decreases, SPL and casual at the same time increased by acoustic propagation distance is inversely proportional to the square of the distance decay away from the speaker distance and azimuth different audience areas, if these two decay right choices, you can make two attenuation to compensate each other, so more uniform sound field, understand the speaker's power handling capability, we must first understand how the speaker driver is corrupted, damaged drive in two modes: Jiaming Yang Cheng 1393 + 90 664 + 17 * City technology market in Milan sun, Building 5 2 A voice coil unit 208 is overheating damage (voice coil burned, hot deformation, and breakdown between the ring), the other is the amount of displacement of the diaphragm drive has exceeded the limit, so that the cone speaker / or around elastic component damage, usually occurs in the low-frequency signal Henan line array contains a lot of sound engineering company to undertake large amplitude.
