I've never tried this, but it seems like you'd get some type of 
squealing feedback issue doing it.  Even through a mic is a 
receiver of sorts, converting sound waves to electrical 
impulses, it's also a speaker in a manner of speaking because 
it works off the same electromagnetic-induction principle.  If 
you hook a mic up the right output port, it can actually be a 
speaker and you can actually hear audio coming out of the mic's 
diaphragm, and a speaker can be used as a mic in the inverse 
way.  Of course either way the quality is pretty bad obviously.

You can do this with speakers or headphones, there are dual "Y" 
adapters for headphones because they are an output and there's 
no issue with output going to two devices.  But with input it's 
possible that one mic's input could bleed over into the other 
mic's output going down the line into the input jack causing 
feedback, and I don't just meant acoustically (which can be 
avoided by making the distance between the mic's large), but 
electrically as well.  You can always try it, but after 
recording a few seconds stop and listen to the playback to see 
if there is any feedback.

You can probably use one of the headphone dual Y adapters for 
this, just make sure the jacks are compatible.  This would 
probably be with a mini 3.5mm jack, and you'd need to consider 
a mono/stereo adapter in there since headphones are stereo and 
mic's are usually mono.

Good morning all.
A 'double adaptor'...is such a thing available, which will 
allow me to
connect 2 microphones to the single input point on my lap top 
computer. If
not, is there another way of doing this?
Thank you
Harold Windle
