Abstract: Disclosed are a sound device and a portable terminal. The sound device includes a first vibration system including a bobbin voice coil, the bobbin voice coil being provided behind a first diaphragm and fixedly connected to the first diaphragm, the bobbin voice coil including a bobbin and a voice coil body formed by winding voice coil leads on the bobbin, one end of the bobbin away from the first diaphragm at least partially configured to protrude from the voice coil body; a second vibration system including a second diaphragm opposite to the first diaphragm; and a magnetic circuit system between the first diaphragm and the second diaphragm, the magnetic circuit system being provided with an avoiding portion. One end of the bobbin away from the first diaphragm is movable to penetrate through the avoiding portion and is fixedly connected to the second diaphragm.
