What is the difference between point source and line array speakers?
Line array speakers are also called linear array speakers. Multiple speakers can be combined into a usb bluetooth speaker group (line array group) with the same amplitude and the same position is called a line array speaker. A linear array is a group of closely spaced radiating elements arranged in a straight line with the same amplitude and phase. Line array speakers are mainly used in large-scale sports games, large-scale performances and other venues. The directivity of the line array speaker in the vertical plane of the main axis is a narrow beam, and the energy superposition can radiate from a long distance. The lower end of the curved part of the linear column covers the near area, forming coverage from near to far. The sound coverage of line array speakers is wide, but it does not change the sound quality in essence, because he cannot ignore the problem of mutual interference. A speaker refers to a device that converts an audio signal into sound. In layman's terms, it refers to the built-in power amplifier in the main box of the speaker or the subwoofer box. After the audio signal is amplified, the sound is played back by the speaker itself to make the sound louder.
Advantages of linear speakers:
1. The coverage is even and the diffusion is good. 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 coverage from near to far.
2. The improvement of the linear array loudspeaker is more in line with the requirements of technology, process and installation.
3. The sound pressure level is high. According to the analysis with MAPP software, the directivity of the linear array becomes sharper as the frequency increases. When reaching a certain frequency, such as 2kHz, the directivity is radial, that is, lobes appear in the directivity diagram. At this time, the sound wave former formed by the high-frequency speaker works, so that the high-frequency directivity is superimposed and strengthened.
4. Strong directivity, the difference between far and near field is small.
Disadvantages of linear speakers:
Interference of linear arrays. There is a time difference between each speaker in the line array reaching the same listening point. A linear array has a distance difference to a certain observation point. Differences in distance and time will cause interference, and peaks and valleys will appear on the frequency response curve.
