9mm Electromagnetic Buzzer: 30Ω, 3-7V, Side Opening

Does anyone have any reviews on it?
Does it play multiple tunes?
Is it worth it?


I do not know of any reviews for this buzzer. It sounds like you are asking about the tones it can play. It can play many different frequency tones. You can see the frequency response on the buzzer’s product page. Those buzzers are usually used with a microcontroller, so it would play whatever frequencies your controller sends that are within the buzzer’s frequency range.



Thanks Derrill. I really appreciate it. Cant wait to use it on my wall following micro mouse. It would have its own victory tune!

Many Thanks,
