Abstract: A printed circuit board (PCB) device is provided, which includes a base board, a part, and a conductive elastic member configured to electrically connect the base board with the part. The conductive elastic member comprises a non-conductive body and at least one conductive interconnect port provided on the non-conductive body and configured to electrically connect an interconnect terminal of the base board with an interconnect terminal of the part.

Abstract: A method of operating an electronic device is provided. The method includes generating an edition file edited in a form that shares an original file, generating a first sharing file by inserting a watermark into the edition file, transmitting the first sharing file to an external electronic device, receiving a transmission request of a second sharing file corresponding to the original file from the external electronic device, and transmitting the second sharing file to the external electronic device.

Abstract: A method for operating an electronic device is provided. The method includes determining one or more images; determining at least one first sound sources; dividing the first sound source into a plurality of second sound sources; and inserting at least one of the plurality of the second sound sources into the one or more images.

Abstract: A method for controlling a content in an electronic device is provided. The method includes detecting first tag information based on a content accessible by the electronic device, detecting second tag information based on an image included in the content, comparing the first tag information with the second tag information, and displaying information indicating that the content is not original on the content, when the first tag information and the second tag information do not satisfy a reference condition.

Abstract: Disclosed is an electronic device including: a housing having a sound emission hole formed in at least one side thereof; a speaker module which is at least partially accommodated in the housing; and a sound reflection surface formed inside the housing and obliquely facing the speaker module. A sound emitted from the speaker module can be reflected by the sound reflection surface to the sound emission hole. The side acoustic emission type speaker device and the electronic device including the same can be variously implemented.

Abstract: The present invention relates to a charger capable of performing the integrated control and separate control of parallel operations. The charger includes a plurality of charging modules connected in parallel with each other. Each of the charging modules includes a rectification unit for converting input AC power into DC power. The system also includes a power conversion unit, a switching control unit, a DC unit, a detection unit, and a computation control unit. The computation control unit receives the voltage and current, detected by and fed back from the detection unit, computes the voltage and the current, and transmits a control signal required to allow the DC unit to supply a primary constant current, a constant voltage, and a secondary constant current to a battery.
