The base device includes one or more speakers and one or more microphones. For each device, its multiple speakers and microphones are driven independently of the other device when the devices are not docked together. However, when one of the additional functionality modules is docked to the base device, a predetermined optimized audio configuration specific to the particular additional functionality module is set for the combined device. ## Claims ### Claim 1 A method of modifying an audio configuration of a combined device comprising a first independently operable device and a second independently operable device, the method comprising: detecting a docking of the second device to the first device; detecting a device ID of the second device at the first device; resolving the device ID to a predetermined audio configuration at the first device for the combined device; and applying the resolved predetermined audio configuration to the combined device. ### Claim 2 (depends on 1) The method in accordance with claim 1, wherein detecting a docking of the second device to the first device comprises detecting contact of the first and second devices at the first device. ### Claim 3 (depends on 1) The method in accordance with claim 1, wherein detecting a device ID of the second device at the first device comprises receiving a signal at the first device from the second device, the signal containing the device ID of the second device. ### Claim 4 (depends on 1) The method in accordance with claim 1, wherein resolving the device ID to a predetermined audio configuration comprises using an ID table to link the device ID to the predetermined audio configuration. ### Claim 5 (depends on 1) The method in accordance with claim 1, wherein resolving the device ID to a predetermined audio configuration comprises deriving the predetermined audio configuration from the device ID. ### Claim 6 (depends on 1) The method in accordance with claim 1, wherein applying the resolved predetermined audio configuration to the combined device comprises modifying an audio setting of at least one of the first and second devices. ### Claim 7 (depends on 1) The method in accordance with claim 1, wherein the predetermined audio configuration specifies the role of one or more of a loudspeaker, an earpiece speaker and a microphone. ### Claim 8 (depends on 7) The method in accordance with claim 7, wherein the predetermined audio configuration specifies that a noise cancellation microphone of the second device is used by the first device instead of a noise cancellation microphone of the first device. ### Claim 9 (depends on 7) The method in accordance with claim 7, wherein the predetermined audio configuration specifies a type of audio signal to be sent to one or more loudspeakers. ### Claim 10 (depends on 7) The method in accordance with claim 7, wherein the predetermined audio configuration specifies that a loudspeaker of the second device is used by the first device instead of a loudspeaker of the first device. ### Claim 11 A portable electronic device configured to mate to an additional portable electronic device to form a combined device and to automatically adjust a device audio configuration upon mating to the additional portable electronic device, the portable electronic device comprising: a connector array for electrically connecting to the additional portable electronic device; a loudspeaker and an earpiece speaker; a noise cancellation microphone; and a processor configured to detect connection of the additional portable electronic device at the connector array, detect a device ID of the additional portable electronic device upon detecting the connection of the additional portable electronic device, resolve the device ID to a predetermined audio configuration for the combined device and apply the predetermined audio configuration to the combined device. ### Claim 12 (depends on 11) The portable electronic device in accordance with claim 11, wherein the processor is configured to detect a device ID by receiving a signal from the additional portable electronic device containing the device ID. ### Claim 13 (depends on 11) The portable electronic device in accordance with claim 11, wherein the processor is configured to resolve the device ID to a predetermined audio configuration by using an ID table to link the device ID to the predetermined audio configuration. ### Claim 14 (depends on 11) The portable electronic device in accordance with claim 11, wherein the processor is configured to resolve the device ID to a predetermined audio configuration by deriving the predetermined audio configuration from the device ID. ### Claim 15 (depends on 11) The portable device in accordance with claim 11, wherein the processor is configured to apply the resolved predetermined audio configuration to the combined device by modifying an audio setting associated with at least one of the loudspeaker, earpiece speaker and noise cancellation microphone. ### Claim 16 (depends on 15) The portable electronic device in accordance with claim 15, wherein the predetermined audio configuration specifies that a noise cancellation microphone of the additional portable electronic device is used instead of the noise cancellation microphone of the portable electronic device. ### Claim 17 (depends on 15) The portable electronic device in accordance with claim 15, wherein the predetermined audio configuration specifies a type of audio signal to be sent to the loudspeaker. ### Claim 18 (depends on 15) The portable electronic device in accordance with claim 15, wherein the predetermined audio configuration specifies that a loudspeaker of the additional portable electronic device is used by the portable electronic device instead of the loudspeaker of the portable electronic device. ### Claim 19 A modular portable electronic device system comprising: a first independently operable portable electronic device; a second independently operable portable electronic device configured to dock to the first independently operable portable electronic device to form a combined portable electronic device; and a processor associated with the first independently operable portable electronic device configured to detect docking of the second independently operable portable electronic device, identify the second independently operable portable electronic device and set an audio configuration for the combined portable electronic device based on identifying the second independently operable portable electronic device. ### Claim 20 (depends on 19) The modular portable electronic device system in accordance with claim 19, wherein the first independently operable portable electronic device includes an earpiece speaker, a loudspeaker and a noise cancellation microphone, and wherein the audio configuration includes a setting for one or more of the earpiece speaker, loudspeaker and noise cancellation microphone.
