Of course, in some cases, the speaker unit 20 may not include an auxiliary system.

It can be understood that the depth of the offset opening 1121 is the wall thickness of the casing 10, and the depth of the offset opening 1121 is smaller, so in the embodiment, only a portion of the magnetic circuit system of the speaker unit 20 extends into the offset opening 1121, for example, the magnetic yoke is wholly or partially located in the offset opening 1121, so that the magnetic yoke is exposed out of the accommodating cavity 14 from the offset opening 1121. Of course, in other embodiments, the wall thickness of the housing 10 at the position where the abdicating opening 1121 is provided may also be set to be thicker, so as to extend the speaker unit 20 into the abdicating opening 1121 as a whole. In addition, the surface of the yoke facing away from the diaphragm 21 may be substantially flush with the outer surface of the housing 10, or the surface of the yoke facing away from the diaphragm 21 may be lower than the outer surface of the housing 10. When the speaker unit 20 is extended into the receding opening 1121, it is equivalent to moving the speaker unit 20 to one side of the rear acoustic cavity, and under the condition that the thickness of the casing 10 is not changed, the space of the front acoustic cavity 141 can be increased, and further, the aperture of the sound outlet on the wall of the front acoustic cavity 141 can be increased.
