THE DUAL SPEAKER

A dual speaker is provided to transmit a loud sound to a listener by forming a tweeter for reproducing the loud sound on an external part. A dual speaker includes a middle/bass sound speaker unit(10), a loud sound speaker unit(20), a fixed bracket, and a tweeter housing(50). The fixed bracket having the middle/bass sound speaker unit is fixed to emit a sound to a different direction on a ceiling by a bolt. The tweeter housing having the loud sound speaker is rotatably installed on a bottom plane of the fixed bracket. The fixed bracket includes an upper bracket(31) and a lower bracket(32), and forms a groove between the upper bracket and the lower bracket. The fixed bracket installed a ball bearing between the upper bracket and the lower bracket so that the lower bracket is rotated.
