ELECTROMAGNETICALLY-SHIELDED SPEAKER SYSTEMS AND METHODS

摘要

An electromagnetically-shielded speaker (or microphone) system for generating acoustic sounds (or electric signals) based upon electric signals (or acoustic sounds) supplied thereto while minimizing irradiation of undesirable electromagnetic waves. While Various speaker systems can be used, each system has at least one source for emitting the undesirable waves and at least one counter member for emitting counter electromagnetic waves capable of canceling at least a substantial portion of the undesirable waves due to their phase characteristics. The system has at least one electric and/or magnetic shields capable of shielding and/or terminating electric waves and magnetic waves of the undesirable waves, respectively. Various methods of minimizing irradiation of the undesirable waves by such counter members, various methods of shielding the undesirable waves by the electric and/or magnetic shields, and the like, as well as various processes for providing such systems, counter members thereof, electric and/or magnetic shields therefor, and the like.
