Abstract
The utility model provides a coaxial loudspeaker. The coaxial loudspeaker comprises a bass loudspeaker unit and a treble loudspeaker unit. A flexible inner elastic edge which can be used for causing the bass loudspeaker unit to form a relatively sealed magnetic circuit space is arranged between the bass loudspeaker unit and the treble loudspeaker unit. According to the coaxial loudspeaker of the utility model, by arranging the flexible inner elastic edge which can be used for causing the bass loudspeaker unit to form a relatively sealed magnetic circuit space between the bass loudspeaker unit and the treble loudspeaker unit, the relatively sealed magnetic circuit space is generated in the bass loudspeaker unit, so when air movement is driven by the vibration of bass coils, the inner elastic edge is driven by the air to play a role in the pulling and driving of the air movement, so the bass effect is improved. Meanwhile, through the addition of the inner elastic edge, the bass vibration area is effectively increased, and a more richer sound effect is realized.
