Abstract: In an example, a speaker device may include a first transducer and a second transducer. The first transducer may include a first diaphragm, a first magnetic circuit, and a first voice coil disposed in a magnetic gap of the first magnetic circuit to cause vibration of the first diaphragm. The second transducer may include a second diaphragm, a second magnet circuit, and a second voice coil disposed in a magnetic gap of the second magnetic circuit to cause vibration of the second diaphragm. Further, the speaker device may include a magnetic plate having a first surface coupled to the first transducer and a second surface coupled to the second transducer. The first surface is opposite to the second surface.
