The present invention discloses a speaker device capable of restraining polarization, a method for adjusting a diaphragm balance position of the speaker device and a method for adjusting diaphragm compliance performance of the speaker device. The speaker device comprises a vibration system, a magnetic circuit system, a shell accommodating the vibration system and the magnetic circuit system, a first electret layer, a second electret layer and a third electret layer, wherein the first electret layer, the second electret layer and the third electret layer have the same electric charge polarity; the first electret layer is attached to the vibration system; the second electret layer is attached to a first fixing component above the vibration system and opposite to the first electret layer; the third electret layer is attached to a second fixing component below the vibration system and opposite to the first electret layer; and the first electret layer, the second electret layer and the third electret layer are parallel to one another. In the present invention, an electrostatic field force is adopted to restrain the polarization of a diaphragm in a vibration direction.
