Rear Glass Cars For Subwoofer

Rear glass membrane will directly serve as speaker, not as shown in the picture. Speakers mounted under the rear glass

Director of Magna International Inc. products, Greg Rizzo said the company has successfully made the rear glass as a sub-woofer for sound systems in cars. "We have successfully made the rear glass as a speaker," he explained while demonstrating AcoustiVision on Chrylser 300 and reported by the Detroit News yesterday.

Explained, Magna using the rear glass panel as a speaker membrane and attach the two eksiter at the bottom. Explained, this subwoofer amplifier that is activated by the trunk. Amplier duty to raise the voltage from 12 volts to 200 volts. Voltage flows into a eksiter and produce sound.

Manufactured in 2015

For this, the glass sealant was given which allowed him to move up and down to produce bass or low frequencies. "This is a new way to menghasilkansuara in the car," said Rizzo. Added, will also be applied to the tweeter in front. However, replacing glass technology subwoofer, according to him is a big breakthrough.

Further, the advantages of using glass as a membrane behind the subwoofer, audio systems will be reduced weight, less power consumption and space required is not much. Understandably, a large subwoofer, often confiscate luggage space, is now integrated in the rear glass.

Exposed, on the basis of the glass panel mounted electronic components. The sound produced by the rear glass is not heard outside. This technology has been developed over the past four years and only now achieving results in accordance with the desired. The next step dalah make glass components in high volume and ensure that contracts with car manufacturers. Magna estimates are able to market the rear glass that also functions as the subwoofer is in 2015.

Piezoelectric tube

Although Rizzo did not explain the details behind the development of glass as a subwoofer, is actually the invention of this concept has been discussed, car audio experts in 2005. One is the Urban Emborg, President A2 Acustics from Sweden. It is said, the glass rear speakers - also called giant subwoofer - can be installed easily. The reason, glass and electrical components can be packaged in one unit before being installed in the car

The concept behind the glass subwoofer A2 is a small tube diameter of 10 mm, fitted lined up at the bottom of the rear glass. The tube is made of material "piezoelectric". This latter material will elongate and shorten the time electrified and subsequently cause a vibration in the glass. Well, that's what produces the sound vibrations and could only be heard from inside. When mempresentasinya, A2 Acoustics already thinking about the technology to produce them in bulk.

At the same time, Colin Novak, a researcher from Auto21, Canada also has presented the subwoofer behind this glass. Some Novak same concept with Urban Emborg, using piezoelectric tube. But in the bottom of the glass, Novak uses a very sensitive spring.

It is said, this glass subwoofer no longer requires a large luggage space. Characteristics of this subwoofer, audio brother increasingly tight in the interior, is also a great increase its ability to inhibit noise from outside. Great!.
