Hi all.
If the terminals of a standalone dynamic speaker or headphone transducer are shorted together, what do we have ? A movable coil in a magnet field.
If there is an audio 'loop' transmitting audio in proximity; would the shorted speaker receive and reproduce the audio as with a wireless induction ?
Or; how to induce audio to a speaker or headphone that is in a magnetic field from a 'loop' ? Shorting its terminals ?
Or; If a shorted earphone transducer is placed near/inside an active speaker coil with its cone removed; will it emit sound... perhaps faint, but emit ? Call the contraption an audio 'loop' and its receiving passive transducer.
-No active electronics/amplification involved for 'reception'-
