According to an embodiment of the present disclosure, the controller 511 (e.g., the processor 120 of FIG. 1) processes information according to an operation of the electronic device 500 and information according to the execution of an application or a function, and controls to display the information according to the execution of an application on the display 514 or outputs the same through the first audio module 517.
The controller 511 makes a control to charge the internal battery 513 by power supplied from an external source through the first connection unit 512. That is, when the second component 503 is attached to the first component 501, the controller 511 controls to receive external power from the second component 503 to operate the first component 501 and charge the internal battery 513 using the received external power. Further, when the second component 503 is attached to the first component 501, the controller 511 controls to interrupt the power supplied from the internal battery 513. Further, since the supply from external power is interrupted when the second component 503 is detached from the first component 501, the controller 511 controls to receive power from the internal battery 513, when detached, in order to maintain a function of the electronic device 500 being executed.
The controller 511 controls the first audio module 517 to transmit an audio signal output from the first audio module 517 to the necklace band (i.e., the necklace band 201 of FIGS. 2 and 3). The audio signal can be transmitted to a first external speaker (i.e., the first speaker 221 of FIGS. 2 and 3) of an earphone through a first line (e.g., the first line 220 of FIG. 2) electrically connected to the first audio module 517 of the first component 501 and/or a second external speaker (i.e., the first speaker 231 of FIGS. 2 and 3) of the earphone through a second line (e.g., the second line 230 of FIG. 2) electrically connected to the second audio module 523 of the second component 503.
When the third detachable component is attached to the first component 501, the controller 511 can determine whether the second component 503 is attached to the third component. When the third component is attached to the second component 503, the controller 511 makes a control to receive power from the battery 521 of the second component 503, which is charged by power provided from the third component. When power is supplied from the third component, the controller 511 controls to interrupt power provided from the internal battery 513.
