Washington, September 6 (ANI): German scientists have come up with a new concept for ultra-flat loudspeakers that can deliver full sound reproduction.

Scientists at the Ilmenau-based Fraunhofer Institute for Digital Media Technology (IDMT) say that such speakers can be integrated inconspicuously on walls or in furniture.

They will present their concept at the Internationale Funkausstellung IFA in Berlin.

Good sound reproduction takes space, at least in the speakers. The loudspeaker membrane must have room to vibrate in order to maintain unimpaired enjoyment.

The quality of the sound in conventional models suffers if speakers are installed on walls or in furniture.

Working in collaboration with Sennheiser electronic, the IDMT scientists have now developed a special loudspeaker that is ultra-flat, but still resonant.

"This new generation offers tonal balance and acoustic pressure at a level that will even allow the use in the professional movie or concert segment in the future," reports Dr. Sandra Brix from IDMT.

To make this possible, the researchers took their inspiration from the loudspeakers of premium headphones.

"We are opening up a new application area for our highest quality electrodynamic headphone miniature loudspeakers in this alliance with Fraunhofer. Because of their compact overall depth, they are excellently suited for use in the flattest loudspeaker boxes, without any losses in tonal persuasiveness," says Prof. Dr. Jurgen Peissig, head of the Signal Processing and High Frequency research department at Sennheiser electronic.

They are arranged in groups so that they allow audio quality that has not been seen in the past.

"Even if these flat panel loudspeakers are placed directly on the wall or integrated into media equipment or furniture, they can reproduce a frequency range from 100 hertz to 20 kilohertz. This distinguishes our new concept from conventional flat panel loudspeakers that achieve response characteristics at this level only if kept at a certain minimum distance from the wall," says Brix.

Thanks to the new design and sound, a large number of loudspeakers can now be discreetly integrated into the surroundings. (ANI)
