发明名称 Acoustic sound effect correction system having two electromagnetic fields created one with voltage varying signal/second constant field producing resultant dynamic field following force gradient/dynamic sensitivity.
摘要 The sound creation process moves air or magnetic particles. There are two electromagnetic fields created on voltage varying an audio electrical signal and the other having a constant field. A resultant dynamic electromagnetic field transmits naturally the ambient surround particles generating a sound following a smaller force gradient following the dynamic sensitivity.
