intelligent system

The importance of audio network systems in modern speaker design is increasingly prominent. In the 1990s, audio network systems were expensive, but now with the rapid development of processing power and the emergence of various standards, audio network technology has become an expected part. The reform of internal electronic components makes it easy for us to distinguish new speakers without this technology. The audio network system, from quick installation to simple control, greatly enhances the user experience with its reporting and diagnostic functions. Most audio systems now include electronic components and digital signal processors that ensure each speaker can be tuned to provide optimal sound effects for the area and entire venue it covers. As a typical example of beamforming technology, the use of digital control technology to control sound distribution has successfully dealt with difficult reverberation spaces such as airports and churches, bringing huge acoustic benefits to these spaces. The internal processing system allows designers to combine the outputs of multiple drivers together, ensuring that sound only reaches where the designer wants it to go. In the near future, we can imagine that speakers will have more functions when they are released, thanks to the computing power provided by tiny chips, which means that computing power can be improved inside the speaker enclosure.

Size optimization

The advancement of materials science has brought significant changes to the design of speakers. Large and heavy ferrite magnets have been replaced by smaller and lighter rare earth metals such as neodymium, creating smaller devices that can provide more energy. This makes product design increasingly compact, capable of producing sleek and stylish speakers that no longer conflict with interior design, while still having sufficient impact to provide the sound pressure level and clarity required for acoustic design. The most common is the slender and elegant design, which can be customized according to the RAL color chart and seamlessly integrated into the overall appearance of the venue. For example, the latest example comes from the B8-SUB speaker from d&b audiotechnik, which has a height of only 170mm, a low frequency extension lower limit of 43Hz, and a maximum sound pressure level of 122dB. It can be installed horizontally or vertically under stages, stairs, or ceilings, or used in conjunction with small, medium, and tall d&b speakers, providing the versatility that most end users expect.

safety standards

With the European EN54 safety evacuation standard becoming a globally recognized standard, manufacturers are seeking to obtain this certification for their products. Many countries have adopted this standard and also added music programs to ensure public safety. This strict process has led to significant business growth for some manufacturers. It not only meets the needs of interior design, as BGM and PA/VA can be played through the same system, reducing the number of speakers required for the project, but also enhances the status of audio design in the design industry. Although there is still a long way to go for audio to receive the same attention as stage scenery, this additional factor will definitely be of great help to the development of audio design.
