A portable electronic device that produces an audio output signal, may have a plurality of speaker types connected to the device, and is capable of modifying the audio output signal to more effectively use the sound reproduction capabilities of the connected speakers. In addition to an internal speaker, many portable electronic devices have jacks for connecting external speakers. These external speakers generally have different audio and electrical characteristics than the internal speaker. In one embodiment disclosed herein, a mobile radio modifies its audio output signal to better match the type of external speaker being used by the mobile radio to reproduce sound. |
