Apparatus and method for reproducing an audio signal

摘要

There is provided an electronic device having an audio system for reproducing audio signals. An exemplary electronic device has an analog region and a separate and non-overlapping digital region. The electronic device comprises an analog ground plane disposed within the analog region and a digital ground plane disposed within the digital region. Digital circuitry is disposed opposite the digital ground plane, wherein digital signals are routed on or over the digital ground plane. Analog circuitry is disposed opposite the analog ground plane, wherein analog signals are routed on or over the analog ground plane. At least one audio output channel disposed opposite the analog ground plane.

1. An electronic device having an audio system for reproducing audio signals, the electronic device comprising:
an analog region; a digital region that is separate and non-overlapping with respect to the analog region; an analog ground plane disposed within the analog region; a digital ground plane disposed within the digital region, wherein the digital ground plane and the analog ground plane are electrically connected by a single-point contact, the single point contract comprising a connecting member that connects the digital ground plane to the analog ground plane; digital circuitry associated with the digital ground plane, wherein digital signals are routed on or over the digital ground plane; analog circuitry associated with the analog ground plane, wherein analog signals are routed on or over the analog ground plane; and an audio output channel associated with and shielded by the analog ground plane, wherein the audio output channel comprises elongate members comprising a left channel, a right channel, and a ground return channel, the ground return channel disposed between the left channel and the right channel, and wherein the ground return channel is disposed along and opposite the analog ground plane and electrically connected to the analog ground plane.
