Which quiz or buzz-in-style TV shows have you watched? In these types of shows, buzzers are used. Some organizations also employ buzzers in their knowledge buzz-in activities. A buzzer typically features functions such as timed buzz-in, timed answers, display of team numbers, display of time, violation, reset, buzzer sound, fouls, and time-up signals. It can also be pre-set with buzz-in time limits, answer time, and timing. In competitions and recreational activities (buzz-in events), it can accurately, fairly, and visually judge the buzz-in participants. It indicates the first buzz-in participant through indicators such as indicator lights, digital displays, and warning displays.
The buzzer system is generally divided into electronic buzzers and computer buzzers. Computer buzzers are further divided into wireless computer buzzers and wired computer buzzers.
This class introduces a relatively simple buzzer, which has the same operating principle as a real buzzer.
