Description: This through-hole speaker is great for projects where you need something that sounds better than a piezo buzzer but don't have room for a full-blown speaker. This 30mm diameter speaker is encased in plastic and will handle about 100mW of power.

Features:

  • 8 ohm
  • 0.1W (0.2W max)
  • 30mm diameter

  • Whoa. That is one shiny new quarter!

    ( Also, nice speaker. )

  • Reminds me of the ones you used to see on modems.

  • Ha, I just pulled this exact speaker out of an old desktop computer.

  • Can this be driven by an Arduino and can I use your Mono Audio Amp Breakout - TPA2005D1 with it?

  • Can this be driven with an Arduino?

    • Yep. Just hooked one up to test it out. Less loud but also much less tinny than a buzzer.

  • This looks like the same speaker on the ThinkGeek evilTrons, ya?

  • The video says 0.1 inch spacing on the pins, but it sure looks like it’s a multiple of that, maybe 0.6 inch. Those leads look a little thick to be putting in a breadboard too - seems like it would take some of the grip out of any holes it was in.

    • ‘0.1" spaced’ is a very common phrase to denote exactly that, a multiple of 0.1".

    • Read the datasheet! Yeesh.

      They’re 1mm pins, normal 22ga breadboard wire is 0.64mm in diameter. So a little thick, yes.

      They’re spaced 15mm apart, which is 0.591 inches, approximately 0.6 inches. That should be close enough to make it fit; the pins are probably tin-plated copper which is pretty flexible.

      However, note that the tolerances are pretty loose: +/- 0.1 on the diameter, +/- 0.5 on the spacing. You might get a part that doesn’t fit, e.g. 1.1mm pins and 14.5mm = 0.57" spacing. Make the holes 1.6mm diameter in any PCBs and any spec-compliant parts should fit. Those tolerances are so loose that I suspect the manufacturer was just playing it safe and the parts you get will all be better than that.

    • 0.1 inch spacing can also mean a multiple of that, along as the pitch is a multiple of 0.1 inch. As for the leads, Id have to agree with you on that they look rather thick.
