Linear sound column system based on MBS multi-beam synthesis technology
2025.06.27
MBS (Multi Beam Synthesis) multi-beam synthesis technology (patented), through original research on beam formation, solves the drawbacks of traditional sound column systems, that is, when the sound beam forms the main beam, it will inevitably bring useless and interfering side beams. The formation of side beams causes acoustic interference to the system and brings a series of problems: such as the generation of a dressing effect, which leads to an uneven sound field and easily causes howling; the generation of side beams greatly reduces the efficiency of the main beam, causing the cylindrical wave to be transformed into a spherical wave prematurely, and the radiation distance is sharply reduced. The useless sound waves radiated by the side beams are reflected multiple times in space, such as the ceiling and floor, affecting the clarity of the language.
At present, the technical means adopted by mainstream manufacturers in the world to deal with the side bends caused by sound beams are more to suppress their occurrence. Some of them are through physical methods or special customization of units, and some are through electronic DSP technology. The effects are different. MBS multi-beam synthesis technology adopts a more reasonable processing method. From the theoretical principle, it is inevitable that side bends will be caused when the sound beam forms the main bend. If the side bends are eliminated by suppression, the formation of the main bend will also be weakened. MBS technology is based on theoretical principles. Through special waveguide design and special driver processing, it can synthesize the side bends that were originally regarded as redundant and useless into the main bend sound beam, thereby eliminating the negative effects of side bends and enhancing the main bend energy.
Key Features:
1.The side-channel energy is transferred to the main channel and gathered in the predetermined listening area, thereby improving the direct sound and range.
2.It eliminates useless reflections caused by the free radiation of sound waves in the vertical direction into the space, such as reflections from buildings such as ceilings and floors. For environments with poor building acoustics and long mixing time, very clear sound reproduction can be obtained.
3. Reduce the occurrence of howling. Useless side-sound propagation in space can easily cause a dressing effect, resulting in uneven production and easy to cause howling. MBS technology makes the sound field more uniform, thereby reducing the occurrence of howling. The unit used is a 4-inch full-range speaker developed in cooperation with FaitalPRO, Italy, with 50 years of R&D and production experience, to ensure accurate synthesis of the sound beam.
