An electronic device includes: a frame including a side wall and at least partially forming an antenna; a bracket provided within the frame; a first printed circuit board provided on the bracket and including at least one grounding portion; a second printed circuit board provided within the frame; and a screw, where the second printed circuit board includes: a first portion coupled to the first printed circuit board; an extension portion extending from the first portion between the side wall of the frame and the bracket; a second portion extending from the extension portion between the first printed circuit board and the bracket; and a conductive trace extending from the first portion to the second portion through the extension portion, and where the conductive trace is electrically connected to the at least one grounding portion of the first printed circuit board in the second portion.

Wearable electronic device

An electronic device having a noise removal function is provided. The electronic device includes an ear jack interface configured to operatively connect with an earphone, a key recognition unit selectively connected to a microphone contact terminal of the ear jack interface, the key recognition unit being configured to recognize a key input of the earphone, and a switching circuit configured to electrically connect or interrupt the key recognition unit to or from the microphone contact terminal according to a key input of the earphone.

Electronic device having noise removal function

An apparatus for reducing TDMA noise in a terminal transceiving a wireless signal in a TDMA scheme, includes an interface unit in which an output accessory is mounted, an audio processor including a virtual ground and transceiving an audio signal to and from an output accessory through the interface unit, a switch unit provided between the interface unit and the audio processor and switching such that a ground terminal of the interface unit is connected to one of a real ground or a virtual ground of the audio processor, and a controller controlling the switch unit to connect the ground terminal of the interface unit to the virtual ground when a call function using the output accessory is activated, in which the switch unit is configured by two or more switches which are connected to each other in a parallel connection.

Apparatus and method for reducing TDMA noise in terminal

A system for detecting the connection of an earphone system to a mobile device is provided. The earphone connection detecting system detects an electrical change from a mechanical change according to the insertion of the earphone jack plug of the earphone system to the jack interface of the mobile device, via a switching device electrically isolated from the earphone system, thereby identifying the connection of the earphone system to the mobile device.
