De microfoon (MIC) zet geluidssignalen om in elektrische signalen, die worden versterkt door de transistor (Q2). De versterkte signalen worden naar de basis van een andere transistor (Q1) gestuurd, die de LED aanstuurt om licht uit te stralen. Hoe luider het geluid, hoe helderder de LED.\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv style=\"line-height: normal\"\u003e\n\u003cspan style=\"font-size:
