The new invention by the Delphi Automotive is that it has come up with two new vehicle sound generators which are capable of warning pedestrian of approaching hybrid and electric cars. These cars will be affixed by sound generators that can be of great help to the manufacturers of cars across the world. The generators are not only environment friendly but are light weight, compact and inexpensive. It also have some distinctive features that the single-box solutions are lead-free, waterproof and temperature resistant. General Director, Electronic Controls product business unit at Delphi, Beth Schwarting stated that in future, hybrid and electric cars warning sounds will be needed in North America and Europe. He also reveled that Delphi has come up with environment friendly generators whose are called sounders these make the people aware of the approaching hybrid and electric cars which never makes sounds without the sound generator. Wanna known more about these electronic sounder system, the two sounders, the first one is almost three times lighter than the conventional multi-box system. It uses near about 90 percent less power, therefore it makes it more environment friendly. The packaging would be simpler by the size and weight of the new sounders, however the it helps in reducing design, test and manufacturing cost. Delphi has even developed a great sounder which uses a cone speaker, these are use in the application required for high quality sound. The magnet based system is almost 66 percent lighter than the conventional speaker system. Both of these systems are capable enough to successfully incorporate a 32 bit microprocessor with long time memory, which would be the link to the car's audio class-D amplifier.
