Abstract

An electronic amplifier device amplifies magnetic audio signals emanating from a portable electronic device placed thereon. The electronic amplifier device includes a housing having a designated area for placement of the portable electronic device thereon, an amplifier circuit, and at least one loudspeaker electrically coupled to the amplifier circuit. A wireless audio coupler circuit situated within the electronic amplifier device includes a magnetic signal pick-up coil which is situated in close proximity to the designated area on the housing. The magnetic signal pick-up coil senses magnetic signals emanating from the portable electronic device placed on the designated area of the housing, and the electronic amplifier device amplifies these signals and provides them to the loudspeaker.
