The description is missing this piezos specs:I measured:11mA @3.0V, 12mA @ 3.3v (Can be driven by an Arduino output, best to connect the + of this to 3.3v and the other terminal to the Arduino output, output low beeps).70db @3 feetResonant Frequency is Approximately 3kHzSelf resonating (only need to apply a voltage)These are NOT magnetic, they are piezo elements.Answers to some of the questions in other reviews:The "Remove after washing" label is placed on the piezo buzzer for production purposes. In production, PCBs are soldered than washed to remove flux. The label is placed to keep the washing solution out of the sound hole on the piezo.This is not a speaker, you cant play audio through it without distortion.One review said they needed a driver for it to beep - I'm not sure why he had a problem, I just connected it to 3V and it beeped.

Producen un ruido muy alto y son exelentes para trabajar con proyectos de electrónica.

Of the 20 five (5) were dead and 1 was so high pitched I think only dogs could hear it.Several others barley worked and were very soft and high pitched.So only about half were usable and of those, about a third were at a higher pitch than the others.Even with the ones that worked the pitch was not very consistent between units.

These work great with the Raspberry Pi as I believe these are of 3 volt construction enabling them to be driven directly by one of the Raspberry Pi's GPIO pins. They are surprisingly loud given how small they are. Very easy to work with as you can quickly and easily plug them into a breadboard. Highly recommended. Would buy again.

These are really great. I purchased them for doing electronics tinkering and experimentation with my nieces and nephew - we are still adding these to everything that we can think up. Great for the inventors in the house.

These buzzers DO NOT contain an oscillator. They only work if you add an oscillator into your circuit.

Super simple to set up and use. Not quite sure what sticker on one end refers to. It says, "remove after washing". Anyone? But they work great!

Basic and good, can make a gentle hum or an iratating whine depending on how strick you stick to the correct voltage. For some reason they all have a label "remove seal before washing", probably a typo but but usefull none the less to see what ones you been playing with. Pins a bit short possibly but not too short for a breadboard or for soldering to a pcb board, any other type of connecting might be problematic depending on your skill and expertese (which face it is bound to be far better than mine)

Que dire, j'avais besoin d'un buzzer pour restaurer et mettre au gout du jour un vieux jouet des années 60.Ils produisent un son plutôt correct et audible, sans être trop fort, avec une tension de 3v (en l’occurrence, j'utilise 2 piles AAA pour l'alimenter)Très bien !

tres fragiles lors de la soudure
