1. A speaker device comprising:
a first transducer comprising:
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;
a second transducer comprising:
a second diaphragm;
a second magnetic circuit; and
a second voice coil disposed in a magnetic gap of the second magnetic circuit to cause vibration of the second diaphragm; and
a magnetic plate having a first surface coupled to the first transducer and a second surface coupled to the second transducer, wherein the first surface is opposite to the second surface;
wherein the magnetic plate is to couple magnetic flux generated from the first magnetic circuit and the second magnetic circuit between the first transducer and the second transducer.
