Understanding Earphone / Headphone Specifications - Shure

WebA crystal set radio is composed of five basic parts: an antenna, coil, tuning capacitor, crystal detector and earpiece (or headphone). Any piece of wire (or indeed metal) can act as an antenna. As the radio waves pass across the antenna they create tiny voltages in the wire. In general, the longer the wire the larger the voltage produced. WebThe earpiece looks like it is low impedance - either 8 ohms or perhaps a few hundred ohms. Without a tuned circuit you need all the sensitivity and lack of loading that you can get. Use of a very very high impedance "crystal earpiece" will make a significant difference. Your general construction is excessively rough for what you are trying to do. WebA crystal earpiece makes a good, simple, cheap tracer. Using the audio part of a transistor radio will also work but the input impedance is low and may load enough to make a good circuit appear weak or defective. There are circuits on the web that precede an LM386 amp with a FET input stage. I built one years ago and it is a very handy little item. top wheelchair companies

WebAug 15, 2010 · However, I would still look for a crystal earpiece and make sure your tuned circuit is actually covering a useful band. It is almost 100% certain that it is NOT if you have just grabbed parts at random. This is ESPECIALLY true if you're still using that toroid core inductor that was almost certainly never meant for this purpose. WebCrystal radios work best with high impedance earphones like crystal earphones. He has installed banana jacks in the front, one for ground and one for hot by the look of it. Find a crystal earphone and strip off the 3.5mm and wire up one of each side to a banana plug and you should be good to go. 10 on_protocol • 4 yr. ago

WebNov 15, 2011 · "Crystal" may have (at least) two different meanings for a receiver or transmitter. To add to the mix, a "crystal" (diode) receiver may even be listened to using a "crystal" (piezoelectric) earphone. That kind of earphone is actually a distant relation of the other kind of crystal which might be used in a transmitter.
