Hi there, Im working on a diy acoustic tube headset, The FBI style ones. I use them at work with 2 way uhf radios and what is available is complete junk so Im going to make my own.
The design should be simple, i just need a transducer connected to a ear tube, a switch with a microphone in it, and the wires and trs assembly.
The switch and microphone circuit is pretty basic but Ill take input if you're willing, i might go for a noise cancelling microphone and would appreciate any advice on component selection.
What i really need help with is the transducer, I think a balanced armature driver would be the best option for me. I dont need any high fidelity acoustic performance, I just need reliable sound so I can hear the radio communication clearly.
Im getting lost in the specs for these armature drivers so i figured i would post here, you seem to be real pros at this stuff.
The headsets we use have an 8ohm impedance transducer.
//Edit. they are 220ohm impedance.
Thanks in advance!
