1, with different design structures.
(1) linear array loudspeaker
Linear array loudspeaker is a group of radiating units arranged in a straight line from top to bottom, with the same amplitude and phase as close as possible. Because they are in phase, the speakers are closely connected to each other. A line array can be regarded as a complete loudspeaker. ?
In a performance in a large space or long-distance sound reinforcement, the audience is often tens of thousands or even more, but at present, the power of a pair of speakers is far from the power needed for listening. So in the past, in such a sound reinforcement place, several pairs or even more speakers were often piled up into a speaker wall, which was called a speaker matrix.
But because of the phase problem, it is such a matrix. Some frequencies in the speaker will interfere. Seriously affect the sound restoration. This is also the reason why wired array speakers were born.
(2) The Tenth Five-Year Plan
This structure was not taken into account in the design of the tenth five-year plan.
2. Different uses.
Linear array speakers are specially designed for large and medium-sized performances. It requires that the sound is a linear cylindrical wave propagation. What is a linear array speaker depends on the details. The authoritative linear arrays are TD, LAX, IBO, WAVK, HZ, acoustic force and so on.
Traditional double 15 is suitable for smaller occasions or indoor occasions.
3. Different purposes
Linear array speakers pursue performance effects, that is, high power.
The Double Tenth Five-Year Plan pursues the reproduction of the original sound.
