Hi.
Am looking for a small speaker, less than 40mm diameter, with a built-in class C or D amplifier powered by lithium cell voltage.
Cell phones/tablets can be loud! in hands-free mode; run on 4V, would work. Knowles makes one with integral amplifier but for earphone use. Do you know of any manufacturer that may have such ?
