Modular, line-array loudspeaker
View Patent ↗This invention relates to a line-array loudspeaker that is configurable to meet the acoustic requirements of a venue. In one embodiment, the line-array includes a combination of far-field and near-field loudspeaker modules which are selectively fixedly connected to each other. Each module includes a first loudspeaker element and a second loudspeaker element. Each of the first and second elements includes a high-frequency transducer assembly and a low-frequency transducer assembly. The far-field modules and the near-field modules are fixedly connected using a rigging system to provide a smooth and continuous transition from a first splay angle to a second splay.
1. A modular line-array loudspeaker, the loudspeaker comprising:
a first loudspeaker module of a first type including a first loudspeaker element, a second loudspeaker element, and a first crossover circuit,
wherein the first loudspeaker module has a first fixed included angle and a first splay angle; and
a second loudspeaker module of a second type including a third loudspeaker element, a fourth loudspeaker element, and a second crossover circuit,
wherein the second loudspeaker module has a second fixed included angle and a second splay angle;
wherein each of the first, second, third, and fourth loudspeaker elements includes a low-frequency driver assembly and a high-frequency driver assembly,
wherein the high- and low-frequency driver assemblies of the first and second loudspeaker elements and the high- and low-frequency driver assemblies of the third and fourth loudspeaker elements are each driven by a first amplifier channel; and
wherein a transition from the first fixed included angle to the second fixed included angle is continuous.
2. The loudspeaker of claim 1 , wherein the first crossover circuit and the second crossover circuit are high-order passive crossover circuits.
3. The loudspeaker of claim 1 , wherein the first type of loudspeaker module is a far-field loudspeaker module, and the second type of loudspeaker module is a near-field loudspeaker module.
4. The loudspeaker of claim 1 , wherein the low-frequency driver assembly includes a woofer and the high-frequency driver assembly includes a compression driver.
5. The loudspeaker of claim 1 , wherein the first splay angle is less than the second splay angle.
6. The loudspeaker of claim 1 , wherein at least one of the first, second, third, and fourth loudspeaker elements is selectively attenuatable.
7. The loudspeaker of claim 1 , wherein the low-frequency driver assembly includes a low-frequency transducer and the high-frequency driver assembly includes a high-frequency transducer.
8. The loudspeaker of claim 1 , wherein the first fixed included angle and the second fixed included angle include trapezoidal angles.
9. The loudspeaker of claim 1 , further comprising a rigging assembly configured to contiguously couple the first module to the second module.
10. The loudspeaker of claim 1 , further comprising tie plates configured to connect the first module to the second module.
11. The loudspeaker of claim 1 , wherein each of the first, second, third, and fourth loudspeaker elements includes a mid-frequency driver assembly, an ultra-low-frequency driver assembly, and an ultra-high-frequency driver assembly.
12. The loudspeaker of claim 1 , wherein the high-frequency driver assembly includes a ribbon type transducer or a piezo array.
13. The loudspeaker of claim 1 , wherein the first splay angle is an angle between respective radiated acoustic centers of a first front panel and a second front panel of the first and the second loudspeaker elements.
14. The loudspeaker of claim 1 , wherein the first loudspeaker module has a first mounting angle that is less than the first slay angle.
15. The loudspeaker of claim 1 , further comprising a first mating junction configured to couple the first loudspeaker module to the second loudspeaker module.
16. The loudspeaker of claim 1 , wherein the first loudspeaker module has a horizontal coverage angle.
17. The loudspeaker of claim 1 , wherein the first crossover circuit and the second crossover circuit are active crossover circuits.
