Provided is a speaker device achieving thinning and cost reduction. The speaker device includes a first speaker unit and a second speaker unit. An outer peripheral side of the speaker unit is provided with a folded portion protruding to an opposite side of a sound emission direction P. A flat portion is provided inside the folded portion. An opening is provided inside the flat portion. A voice coil bobbin is secured to the opening. A speaker unit is arranged in the voice coil bobbin. An external-magnet-type magnetic circuit is provided in the speaker unit. As a magnet of the magnetic circuit, a ferrite magnet having a large volume is used.

Speaker device having diaphragm with folded portion

Provided is a speaker device achieving thinning and cost reduction. The speaker device includes a first speaker unit having a first diaphragm connected to a voice coil bobbin, and a second speaker unit having a second diaphragm provided inside the voice coil bobbin. When a sound emission direction P of the first speaker unit and the second speaker unit is upward and an opposite direction of the sound emission direction P is downward, a position of an upper end A of the first diaphragm is substantially equal to an upper end B of the second diaphragm.
