Electronic device having touch sensor

摘要

An electronic device with a touch sensor includes a body mounted with an electronic element, and a cover detachably coupled to the body. The body includes a signal generating circuitry that generates an electric signal, a first antenna that transmits the electric signal, and a touch processing circuitry that processes a touch signal received through the first antenna. The cover includes a touch sensor that is driven by the electric signal and recognizes a touch, and a second antenna connected with the touch sensor. The second antenna receives the electric signal and transmits a touch signal sensed through the touch sensor unit.
