Abstract

An electronic device and method are provided. The electronic device includes a built-in microphone; a Bluetooth communication module configured to wirelessly connect to a first wireless external device including a speaker and a second wireless external device including a speaker; and a controller configured to detect a call establishment, if the call establishment is detected while one of the first and second wireless external devices is connected to the electronic device, operate the built-in microphone to receive sound based on information regarding the connected one of the first and second wireless external devices, and if the call establishment is detected while both of the first and second wireless external devices are connected to the electronic device, select one of the first and second wireless external devices and provide an incoming call audio signal received via the call establishment to the selected one of the first and second wireless external devices.

First claim

What is claimed is:

1. A mobile phone capable of coupling to a wireless external device and a wired external device, the mobile phone comprising:
a built-in speaker;

a socket configured to couple with the wired external device being a first device including a speaker, but not including a microphone, or a second device including both a speaker and a microphone; and
a controller configured to:
obtain information of one or more devices presently and operatively coupled with the mobile phone, among the first device, the second device, and the wireless external device, and
in response to a call connection event:
when the mobile phone is presently and operatively coupled with only the first device without the microphone, and the first device does not include a microphone according to the information, obtain an audio input via the built-in microphone,
when the mobile phone is presently and operatively coupled with only the second device with the microphone, and the second device includes a microphone according to the information, obtain an audio input via the microphone of the second device, and
when the mobile phone is presently and operatively coupled with both the wireless external device and the second device with the microphone, and both of the wireless external device and the second device includes a microphone according to the information, selectively obtain an audio input from one of the microphone of the wireless external device and the microphone of the second device.

2. The mobile phone of claim 1 , wherein, in response to the call connection event, the controller is further configured to:
when the mobile phone is presently and operatively coupled with both the wireless external device and the first device without the microphone, and each of the wireless external device and the first device includes a speaker according to the information, selectively provide an audio output of an incoming call through one of the speaker of the wireless external device and the speaker of the first device.

3. The mobile phone of claim 1 , wherein, in response to the call connection event, the controller is further configured to:
when the mobile phone is presently and operatively coupled with both the wireless external device and the first device without the microphone, and one of the wireless external device and the first device includes a microphone according to the information, selectively provide an audio output of an incoming call through one of the speaker of the wireless external device and the speaker of the first device.

4. The mobile phone of claim 1 , wherein, in response to the call connection event, the controller is further configured to:
when the mobile phone is presently and operatively coupled with both the wireless external device and the first device without the microphone, and the wireless external device includes a microphone and the first device does not include a microphone according to the information, selectively provide an audio output of an incoming call through one of the speaker of the wireless external device and the speaker of the first device.

5. The mobile phone of claim 1 , wherein, in response to the call connection event, the controller is further configured to:
when the mobile phone is presently and operatively coupled with both the wireless external device and the first device without the microphone, the wireless external device includes a microphone and the first device does not include a microphone according to the information, and the first device is selected, obtain an audio input via the built-in microphone.

6. The mobile phone of claim 1 , wherein, in response to the call connection event, the controller is further configured to:
when the mobile phone is presently and operatively coupled with both the wireless external device and the first device without the microphone, the wireless external device includes a microphone and the first device does not include a microphone according to the information, and the wireless external device is selected, obtain an audio input via the microphone of the wireless external device.

7. The mobile phone of claim 1 , wherein, in response to the call connection event, the controller is further configured to:
when the mobile phone is presently and operatively coupled with a plurality of wireless external devices, and each of the plurality of wireless external devices includes a microphone according to the information, selectively obtain an audio input from a microphone of one of the plurality of wireless external devices.

8. The mobile phone of claim 1 , wherein, in response to the call connection event, the controller is further configured to:
when the mobile phone is presently and operatively coupled with a plurality of wireless external devices, and only one of the plurality of wireless external devices includes a microphone according to the information, obtain an audio input from the microphone of the one of the plurality of wireless external devices.

9. The mobile phone of claim 1 , wherein, in response to the call connection event, the controller is further configured to:
when the mobile phone is coupled with only the first device without the microphone, and the first device includes a speaker according to the information, provide audio output using the speaker of the first device.

10. The mobile phone of claim 1 , wherein, in response to the call connection event, the controller is further configured to:
when the mobile phone is coupled with only the second device with the microphone, and the second device includes a speaker according to the information, provide audio output using the speaker of the second device.

11. The mobile phone of claim 1 , wherein, in response to the connection event, the controller is further configured to:
when the mobile phone is presently and operatively coupled with both the wireless external device and the second device with the microphone, and each of the wireless external device and the second device includes a speaker according to the information, selectively provide audio output from one of the speaker of the wireless external device and the speaker of the second device.

12. The mobile phone of claim 1 , wherein, in response to the connection event, the controller is further configured to:
when the mobile phone is not coupled with any external device, provide audio output using the built-in speaker.

13. The mobile phone of claim 1 , wherein when the mobile phone is presently and operatively coupled with both the wireless external device and the second device with the microphone, the microphone of the wireless external device or the microphone of the second device is selected based on corresponding priorities of the wireless external device and the second device.

14. A non-transitory computer readable memory storing one or more programs, which when executed by a controller of a mobile phone, performs the steps of:
