Abstract
An operation method of an electronic system includes the following steps. When a first communication module of the electronic device receives a call signal, a controller of an electronic device detects whether an expansion device is electrically connected to the electronic device. Based on a result of the controller detecting whether the expansion device is electrically connected to the electronic device, it is determined whether the electronic system performs sound amplification with a first speaker of the electronic device or performs playing with a second speaker of the expansion device.
