Maxwell 2D/3D and Simplorer for loudspeakers

Founded in 1964, Bose Corporation develops unique sound solutions to meet virtually any audio challenge in any application. While many of the company's products are designed for entertainment and home audio solutions, Bose sound is prevalent in the aviation and automotive industries, stadiums and auditoriums, houses of worship, retail businesses, department stores, and restaurants. Today, the company has operations in the United States, Europe, Canada, Australia, Asia, and South America.

THE NEED
To evaluate loudspeaker magnets and coil assemblies to predict the efficiency and linearity of the electromechanical conversion and to conduct research into new ideas for electromechanical systems

THE SOLUTION
Maxwell® 2D and 3D, Simplorer®

"Maxwell is an important tool for the prediction of loudspeaker behavior," said Thomas Froeschle, Bose vice president of research. "Using Ansoft software, we evaluate loudspeaker magnets and coil assemblies to predict the efficiency and linearity of the electromechanical conversion."

"In addition," adds Froeschle, "we have been extensively using Ansoft products to conduct research into new ideas for electromechanical systems. In that area, we are investigating linear actuators. A linear actuator is a device that moves in a single direction. We are using Maxwell to design actuators that can receive as much as 60 kilowatts of electrical power and produce between 5,000 and 10,000 Newtons of thrust. These are very powerful devices, indeed."

"The software enables us to research concepts very efficiently and has enabled us to investigate design issues more effectively than alternative methods that we have used. Working experimentally can be very slow and tedious. Often, it's hard to evaluate experimental performance because measurements are difficult, slow and expensive," Froeschle explains.
