Claim 0:
1. A speaker device, comprising a frame, a vibration unit, a magnetic circuit unit, and an air-permeable isolation member, wherein the vibration unit and the magnetic circuit unit are fixed to the frame, the magnetic circuit unit is configured to drive the vibration unit to vibrate to produce sound;
the magnetic circuit unit comprising a yoke fixed to the frame, the yoke is fixed to a side of the speaker device away from the vibration unit, the yoke and the frame are spaced to form a leakage port to enable leaking from a side surface of the speaker device;
the frame, the vibration unit, and the magnetic circuit unit jointly enclose to form a sound-producing inner cavity, the sound-producing inner cavity communicates with the leakage port;
the air-permeable isolation member completely covers the leakage port, and comprises a bottom wall and a side wall, the bottom wall is fixed to the yoke, the side wall bends and extends from the bottom wall toward the frame, and the side wall is fixed to the frame; and
the side wall and/or the bottom wall are provided with a leakage hole penetrating the side wall and/or the bottom wall, and are configured to isolate external sound-absorbing particles from entering the sound-producing inner cavity, and the leakage port communicates with the outside through the leakage hole.
