Loudspeaker technology and Applications

The birth of the flat panel speaker technology is a revolution of the speaker technology, which represents a major innovation in the field of speakers. Because it completely changed the traditional speaker has been a piston type motion of the sound principle, and replaced by a millimeter in the form of random vibration. With the development of social science and technology progress, a lot of companies on the flat-panel speaker technology have come, but this advanced technology can be broadly divided into two major categories of Australian system and the UK NXT system, but the quality and cost of the obvious advantages or the United kingdom.
　　At the beginning of 1990s, the British Defense Ministry researchers in order to study the method of reducing the internal noise of combat helicopter, as a part of the focus of the study, scientists have tried to use a composite plane material closed engine, and then use the power noise cancellation technology to reduce noise. But the strange thing is that the noise has not been reduced, but it is the composite plate material such as the speaker is generally due to vibration and sound increased by the internal noise.
So, the researchers thought of using this composite flat material to manufacture speakers, and began to develop the work, the application of a speculative patent, because the British Defense Ministry itself has no resources and no experience to develop this application, it is to find the special interests of the audio industry partners, the patent licensing. Gradually Group Verity set up a company in September 1996, and is committed to the NXT tablet speakers in the field of business, professional and home and other practical applications.
The first NXT technology product is NEC company in 1997 launched a laptop computer, hidden speakers is one of the authorized research and development of a distributed model speaker, which means that the advent of powerful hidden solutions, this paste in the wall products can be completely without affecting the room visual appearance, you can send a clear and delicate sound.
