In the past, in order to meet the requirements of sound reinforcement in large venues (such as large stadiums, sports fields and squares), dozens or hundreds of speakers were often used to form a large "speaker array" or "sound wall" to meet the sound pressure level of the venue. Harmony is overwhelmed by the requirements of the sound field. This type of method has been used for many years and is still in use today. It's just that with the passage of time, the line array speakers are continuously improving and replacing. At first, people gradually discovered that this type of traditional array method can meet the need for sound reinforcement in large venues on the whole, but there are two outstanding results: one is that the large-scale array is complex and inconvenient to use; It is the phenomenon of significant acoustic interference in the sound field of sound reinforcement. Obviously, the existence of these problems can not satisfy the application request for some applications, especially those with high requirements for playback sound quality.
1. Proposal of line array speaker system
In order to deal with these problems, in the past ten years, acousticians and loudspeaker manufacturers have begun to "revisit" the famous American acoustician HF Olson (Acoustical Engineering) in 1957 (Acoustical Engineering)-Book Zhongguan. The description of the branch line array, that is, the line array speaker has the characteristics of good vertical directivity and long-distance sound radiation." But how can the wide-range sound reproduction be realized? As long as the new speaker technology, new plan and processing technology are improved The ability is realized. The French company L-ACOUSTICS first launched the V-DOSC system in 1993. In the following years, some well-known domestic speaker manufacturers have also successively launched their own brand of line array speaker systems. Since 2002 Some domestic speaker manufacturers have also developed their own line array speaker systems one after another.
2. What is a line array speaker system
In short, the line array speaker system can be regarded as a "large full-range speaker." It is based on the fundamental practice of Line Array to provide a similar and retractable speaker system under certain conditions. It must be noted that it is impossible to simply equate the "line array" with the actual line array speaker system. The linear array is basically composed of a set of radiation units arranged in straight lines and carefully spaced apart. The acoustic radiation of these radiation units should have the same amplitude and phase.
3. The basic premise of forming a line array
The basic point for line array to achieve a similar aspirational "line sound source" or "continuous ribbon sound source" is:
① Each acoustic radiator in the array works with a same-phase three-dimensional wavefront;
②The distance between the acoustic centers of the acoustic radiators of the array should be less than half of the wavelength of the highest radiation frequency.
