Etymology
The word "buzzer" derives from the onomatopoeic verb "buzz," which mimics the sound of insects or machinery. The suffix "-er" transforms it into a noun denoting a device that produces such a sound. First recorded in the early 19th century, it originally described mechanical signaling devices and later expanded to include electronic alarms and sports equipment.
