The movement of the coil over the magnet produces an electrical signal. As the diaphragm oscillates forward and backwards, the voice coil moves with it. The rear of the diaphragm is attached to a voice coil, which is a wrapping of wire that sits around a magnet. Before I explain the structure, take a look at this great image. While there are multiple kinds of Dynamic mics, when people use the term “Dynamic microphone” they usually are referring to a “Moving Coil” dynamic microphone. (The method used to turn a sound wave into electrical energy the mic outputs.) What’s the difference between a Dynamic and a Condenser microphone?Įach type of microphone works by a different method of electro-magnetic induction. It's a diaphragm that moves with sound pressure too! This is the same principle as your ear-drum. (Anything you hear is a sound wave.) This vibration is turned into electrical energy that’s transmitted through your XLR cable, or into the internal electronics on USB mics. These are thin pieces of some material, usually plastic or metal, that oscillate in response to sound pressure waves generated by acoustic activity. Otherwise, let’s dive into the basics! :)Īll microphones have diaphragms. If you already know your shit and are just curious about the list, scroll to the end. I do hope to make that post soon, but it’s outside of what I’d like to talk about today and we just don't have the room. While they’ll be briefly mentioned, this is not a post about Audio Interfaces / Pre-Amps, or recording levels sample rates or bit depths. I personally feel like understanding what microphones do, how, and what makes them different is useful to understanding why you don't need to spend $400 on a mic, if you don't feel that way feel free to skip to the end. In this post I’ll be explaining how Mics work, the two main types of microphone, what a polar pattern is and the different types, what a frequency response is, and some other basic information you’ll need to know. This is going to be a lot of information as I’m trying to make it fairly comprehensive so it’s a good reference for people to keep handy. While I do intend this guide to be useful for people of all levels of familiarity with the subject, particularly complete beginners, do note that if you’re an expert you’ll get little out of it other than my personal opinion. ![]() This isn't an area people are expected to have vast amounts of experience with.įinding the right microphone for you is simple and you won’t need to break the bank either. Resources /r/podcasting Wiki Related SubredditsĮvery day on the subreddit the same question gets asked on repeat “What microphone should I buy?” There’s no “right” answer to that question, but there’s a hell of a lot of misinformation out there, and that's understandable. Questions? Posted something that's missing? Ask a mod. Promotional posts for products and services are prohitted unless pre-approved by the moderators.These are okay in comments, when relevant.
