Abstract
Systems and methods for reducing the effects of stray magnetic flux are provided. For example, an electronic device can employ the system and can include a first audio component configured to have a first acoustic phase and a first magnetic phase. The electronic device can also include a second audio component configured to have the first acoustic phase and a second magnetic phase that is opposite the first magnetic phase. The first audio component can be positioned with respect to the second audio component, such that any stray magnetic flux from the first audio component enters the second audio component during operation of the first and second audio components.
