Dual diaphragm electroacoustic transducer

A miniature electroacoustic transducer comprising:

• a transducer housing comprising a sound aperture, and a magnetically conductive first housing portion surrounding a magnet assembly;
• the magnet assembly adapted to generate a first magnetic flux with a first predetermined orientation within a first magnetic gap and adapted to generate a second magnetic flux with a second predetermined orientation within a second magnetic gap;
• a common magnetic flux path comprising the magnet assembly and the first and second magnetic gaps;
• a first moveable assembly comprising a first electrically conductive coil positioned in the first magnetic gap and coupled to a first diaphragm to enable motion of the first moveable assembly in a first direction of motion substantially perpendicular to the first magnetic flux;
• a second moveable assembly comprising a second electrically conductive coil positioned in the second magnetic gap and coupled to a second diaphragm to enable motion of the second moveable assembly in a second direction of motion substantially perpendicular to the second magnetic flux, wherein said magnet assembly comprises a centrally positioned permanent magnet assembly operatively secured to an inner side wall portion of the magnetically conductive first housing portion,
• wherein said common magnetic flux path comprises the magnetically conductive first housing portion.
