Abstract: The present invention discloses a speaker device and electronic equipment. The speaker device comprises a speaker body, an audio signal input terminal connected with the speaker body, and a DC voltage signal input terminal connected with the speaker body. The electronic equipment comprises the speaker device and a DC voltage signal output circuit. The present invention further discloses a method for reducing a low frequency distortion degree of the speaker of the electronic equipment, and the method is realized by additionally providing a DC voltage signal to the input end of the speaker. In the present invention, a distortion degree of the speaker device at a low-frequency working condition can be reduced, and inconsistency of low frequency distortion of the speaker device, caused by mass production, can be reduced.
