The magnetic circuit system is disposed at the magnetic circuit system setting section and includes at least one voice coil which spaced from the first surface of the frame and having a first end and a second end opposite to the first end. The first end defines a virtual plane extending along a radial direction of the voice coil. The virtual plane and the first surface of the first region define a first distance.
