Hi All,
I am looking for a mini speaker with at least 22khz frequency response and supporting micro sd card.
Most of the vendors mentioned that they support like 100Hz to 18 KHz or 100Hz to 20KHz. But my requirement is minimum 22KHz.
I need to buy like 20 in quantity with less than 15USD each. No need bluetooth support, just sd card reader is enough.
Pls help,
Thanks
