Problems solved by technology
When people need to transmit some public information, they often use loudspeakers; although fixed loudspeakers are convenient, their transmission distance is limited, while hand-held loudspeakers, because people's speed is slow, the efficiency of information dissemination is also low. In order to spread information faster, people often use loudspeakers when riding bicycles or driving cars to speed up the speed of information dissemination, but when people drive, it is very difficult to use hand-held loudspeakers. Inconvenient and often dangerous to drive
