I am looking to get my hands on some Pizeo Buzzers that are as small as possible. So far I have found 10mm round, which is good, but I was wondering if anyone knew of ones that are smaller still?

I would prefer to avoid SMD components if at all possible, but I can deal with it if need be. At the end of the day, as small as 5x5mm would be great.

I found a Pizeo Buzzer with 6.5 mm here:

  • \$\begingroup\$ excellent! A mite pricey, but I guess small things usually are. Thanks for the help! \$\endgroup\$ – A.R. Feb 23 '11 at 16:27

    \$\begingroup\$ While sound pressure depends on the surface the piezo is mounted on, a piezo this small won't be very loud. And the resonance frequency is 7kHz, which is a bit high (ears are less sensitive to it) \$\endgroup\$ – Federico Russo Jun 14 '11 at 16:55
