General information [contribute]

Sony web site (July 22, 2009): Our companies are known for creating products that enrich people's lives. Through Sony Corporation of America and its operating companies - Sony Electronics Inc., Sony Pictures Entertainment Inc. and Sony Music Entertainment - we are also dedicated to improving people's lives. Our commitment extends to helping local communities, fostering better educational systems, funding research to cure devastating diseases, supporting the arts and culture, helping disadvantaged youth, protecting and improving the environment and actively encouraging employee volunteerism.

Our philanthropic efforts reflect the diverse interests of our key businesses and focus on several distinct areas: arts education; arts and culture; health and human services; civic and community outreach; education; the environment; and volunteerism. Each operating company has its own philanthropic priorities and unique resources, from product donations to recordings and screenings that benefit a multitude of causes. Sony Corporation of America is a strong supporter of arts and culture. Education and volunteerism are key components of Sony Electronics Inc.'s philanthropic efforts. Sony Pictures Entertainment is a major supporter of arts education and community involvement, with emphasis in Culver City, California, its world headquarters. Collectively, we have also been quick to provide assistance when large-scale disasters have struck. We've helped victims of major hurricanes, earthquakes, wildfires and the attack on the World Trade Center.

The spirit of philanthropy is deeply imbedded in the culture of Sony in America. We're proud of the dozens of programs and partnerships that have touched thousands of lives in all corners of the country and fill the pages of this brochure. Our 20,000 employees have responded positively to this spirit and have given generously of themselves. They've collected food for the hungry, built homes for the poor, cleaned polluted waterways, mentored the disadvantaged and helped in countless other ways that are detailed in the following pages.

Together with our employees, Sony in America is working to improve our communities and the world around us.

John McEnroe (September 2001): Mini System MHC-C9EX PKG uses electrostatic tweeters with 6" motional feedback woofers for its front speakers.

Willy Lefevbre (May 2001): Sony has made an ESL with separate elements for low, midrange an high. The different panels work with different polarization valtages. The low range panel consists of two elements placed 5mm apart. By using very smooth copper stators and a special HV isolation a polarization voltage of 8500 V can be applied. The high frequency element has a membrane stator spacing of 0.3 mm and polarization voltage of 2000V. One speaker weighs 90 KG and a pair costs around $18.000
