Abstract
A loudspeaker arrangement for a vehicle having a magnetic-field-sensitive device, includes a casing, and first and second loudspeakers disposed in the casing. First and second magnets are incorporated in the first and second loudspeakers respectively. The respective magnetic moments of the first and second magnets are arranged to be antiparallel so that the vector sum of magnetic fluxes produced by the first and second magnets will be reduced at the position of the magnetic-field-sensitive device.
