[0002] Emergency broadcasting means that when major natural disasters, emergencies, public health and social security and other sudden public crises occur, the emergency broadcasting equipment provides a fast and fast information transmission channel, and the disaster news or disasters may be caused by the disaster at the first time. The hazards are transmitted to the hands of the public. The existing emergency broadcasting equipment can basically meet people's needs, but there are still some deficiencies. First, the speaker is fixed after installation and cannot be adjusted in direction, resulting in a limited range of sound transmission. , causing people in some locations to be unable to hear the news clearly, thereby reducing the reliability of the emergency broadcasting equipment. Second, the fixed broadcasting equipment does not have a corresponding shock-absorbing mechanism. equipment lifespan
