Abstract: An electronic device is provided. The electronic device includes a communication module, a sensor module, a sound input module, a sound output module, a memory including a buffer, and a processor. The processor is configured to determine whether an external electronic device has at least one speaker and/or microphone, select, a speech reception device from among the electronic device and the external electronic device based on sensing information received when a call is connected, select a speech transmission device, from among the electronic device and the external electronic device based on a comparison of a speech signal received from the electronic device with a speech signal received from the external electronic device when a call is connected, and if the speech transmission device and the speech reception device are different devices, enable at least one microphone included in the speech transmission device, disable at least one speaker included in the speech transmission device, disable at least one microphone included in the speech reception device, and enable at least one speaker included in the speech reception device, acquire an echo reference signal related to reception speech received from the speech reception device and store the echo reference signal in the buffer, determine, based on comparison of the stored echo reference signal to transmission speech received from the speech transmission device, an EPD value relating to an echo signal included in the transmission speech, and cancel the echo signal by using the echo reference signal and the determined EPD value.

Abstract: Disclosed is an electronic device. The electronic device includes a printed circuit board on which one or more circuit components are disposed, and an interposer surrounding at least some circuit components of the one or more circuit components and including an inner surface adjacent to the at least some circuit components and an outer surface facing away from the inner surface and having a plurality of through holes. The interposer is disposed on the printed circuit board such that one or more through holes of the plurality of through holes are electrically connected with a ground of the printed circuit board. The outer surface of the interposer includes a first conductive region electrically connected with at least one first through hole of the one or more through holes, and a non-conductive region, the inner surface of the interposer includes a second conductive region electrically connected with at least one second through hole of the one or more through holes, and the second conductive region includes a region facing the non-conductive region.

Abstract: Disclosed are a method for controlling an operation of a battery on the basis of the state thereof, and an electronic device for supporting the same. The electronic device includes: a battery connector including multiple terminals; a battery detection circuit configured to detect whether a battery is connected to the battery connector; a short-circuit detection circuit configured to detect whether a battery identification (ID) terminal among the multiple terminals is short to a ground, based at least partly on a level of a voltage measured at the battery ID terminal and a predetermined voltage level; and a processor, wherein the processor may be configured to: acquire, from the battery detection circuit, a first signal related to whether the battery is connected to the battery connector; determine whether the battery is connected to the battery connector, based at least partly on the first signal; acquire, from the short-circuit detection circuit, a second signal related to whether the battery ID terminal is short-circuited to the ground; based at least in part on the first and second signals, determining whether: the battery is not connected; the battery is properly connected; or the battery is improperly connected; and control an operation of the battery based at least partly on determining whether the battery is not connected, the battery is properly connected, or the battery is improperly connected.
