Line array sound is a speaker system, and its technology and manufacturing have been developing steadily for many years. Recently, the situation has changed, and linear array speaker systems have appeared at many major sports events and large performances in the world.Linear array is a group of radiating elements arranged in a straight line and closely spaced, and has the same amplitude and phase. Through linear transmission, the transmission distance is increased and the attenuation during sound transmission is reduced.The advantages of linear array sound reinforcement systems are obvious.
(1) Due to the characteristics of the linear array, the directivity in the vertical plane of the main axis is a narrow beam, and the energy superposition can be radiated at a long distance. The lower end of the curved part of the linear column covers the near area, forming a coverage from near to far.(2) The improvement of the linear array amplifier is more in line with the requirements of technology, process and installation. The middle high-frequency part is more special, 2 (JBL) or 3 (V) tweeter outlets are connected together fJ2j, JBL company called it a sound wave generator, E-V company called it a plane wave generator. According to the analysis with MAPP software, the directivity of the linear array becomes more and more uniform with the increase of frequency. When a certain frequency is reached, such as 1000Hz, the directivity is radial, that is, the flap appears in the directivity map. At this time, the acoustic waveformer composed of the tweeter comes into play, so that the high-frequency directivity is superimposed. (3) Linear arrays cannot ignore mutual interference, and linear arrays themselves do not improve sound quality.
