Topic: Audioplayer connection to a microphone input of the smart phone
Question on electrical compatibility. It is necessary to connect to a microphone input of the smart phone to connect a normal audioplayer for earphones (even ordered a special cable-splitter which from 4-contact 3.5'jack does two three-contact - for earphones and for a microphone). But I am not assured that there all compatibly , whether in sense not too big there will be the pressure/currents, produced by a player and would not burn down that in the smart phone. Whether who competently to tell it can is possible so to connect or what resistor in between and if it is necessary - that what and how it to put (sequentially in rupture is necessary, is parallel)?
