Hello everyone.
First of all, if this is not the correct forum for this post, staff, please feel free to move it.
I am a part of a small community that is tangential to field recording, in that we attempt to archive recordings of speakers in public places, with the best quality and least noise, background or otherwise, as possible. The main "tool of the trade" besides using a normal mic close up to the speaker is using small telephone pickups (https://www.newark.com/productimages/standard/en_US/39C0931-40.jpg), which work quite well by capturing the electromagnetic field around the speaker to capture the audio. However, I have noticed that a specific older model of telephone pickup works better than others that I have tried, with a stronger input and better overall frequency range. At this point, I have ordered and tried a total of five different pickups, with no new results to show of any models that can produce better recordings than the main one already known to the community.
A few people in this same community have recently brought back up the idea of possibly winding our own pickup coils or otherwise trying to contract some to be manufactured. However, I know basically nothing about these, besides that they have a coil of wire in them, and I don't know what would produce the best/loudest/most detailed recordings. Through some research and talking to others, I have seen inductors that can be purchased and wired to 3.5 mm cables, and that guitar pickups are another possible option; however, I have no idea what I am looking for specification-wise.
If anyone is able to provide info regarding other options that can capture recordings from speakers' electromagnetic fields, or the technical details regarding this broken pickup () or other specifications, I would greatly appreciate it. Thanks!
