content: not sure what is sub-miniature for you, but if 15-16mm diameter speakers (not piezo but real speakers) are ok for your project then TME has such speakers on stock - approx 1.5Eur a pop + VAT.http://www.tme.eu/en/details/ld-sp-u15.5_8a/speakers/loudity/#

content: Quote from: Dave Turner on January 23, 2015, 10:26:53 pmDon't think so. A bit under 1 kHz an they completely suck. Depend how you would use them however. IMO nothing is even close to mobile phone speakers in this size region. Do you need them for production or one off? Generally you'd search them at the places which supply mobile phone spare parts.

content: Quote from: rob77 on January 24, 2015, 02:11:31 pmYes they all suck. Difference is how much they do. I have some new Nokia speakers. Can give some away at the expense of shipping (approximately 2-2.5 EUR worldwide).

It was his first post and after that he bailed the forum it seems.
