Abstract

A mobile terminal is provided, which includes a housing; a camera placed in the housing; a circuit board included in the housing; a charging coil arranged in the housing; a wireless communication coil electrically isolated from the charging coil; and a magnetic sheet including a front surface, on which the charging coil and the wireless communication coil are arranged, and a back surface. The charging coil includes a first winding portion, a first leg portion, and a second leg portion. The wireless communication coil includes a second winding portion. The first and second leg portions of the charging coil are arranged between the second winding portion of the wireless communication coil and the back surface of the magnetic sheet. A minimum distance between the first and second leg portions and the camera is less than a minimum distance between the first winding portion and the camera.

Claims

exact text as granted — not AI-modified
1 . A mobile terminal comprising:

 the charging coil includes a first winding portion, a first leg portion, and a second leg portion, 
 the wireless communication coil includes a second winding portion, 
 the first and second leg portions of the charging coil are arranged between the second winding portion of the wireless communication coil and the back surface of the magnetic sheet, and 
 a minimum distance between the first and second leg portions and the camera is less than a minimum distance between the first winding portion and the camera. 
   
     
     
         2 . The mobile terminal according to  claim 1 , wherein the first winding portion of the charging coil has an internal dimension spanning at least 15.5 mm. 
     
     
         3 . The mobile terminal according to  claim 1 , wherein the first winding portion of the charging coil defines an internal hollow portion sized to receive a circle having a diameter of 15.5 mm. 
     
     
         4 . The mobile terminal according to  claim 1 , wherein the first winding portion of the charging coil is wound in a shape selected from a rectangular shape, an oblong shape, a circular shape, an elliptical shape, and a polygonal shape. 
     
     
         5 . The mobile terminal according to  claim 1 , wherein the first winding portion of the charging coil is wound in a circular shape and an internal diameter of the circular shape is greater than 15.5 mm. 
     
     
         6 . The mobile terminal according to  claim 1 , wherein the second winding portion of the wireless communication coil is wound in a shape selected from a rectangular shape, a circular shape, a square shape, and a polygonal shape. 
     
     
         7 . The mobile terminal according to  claim 1 , further comprising a battery included in the housing, wherein the minimum distance between the first and second leg portions and the camera is less than a minimum distance between the first and second leg portions and the battery. 
     
     
         8 . The mobile terminal according to  claim 1 , further comprising a battery included in the housing, wherein the battery is placed in a first half along a longitudinal direction of the housing and the charging coil is placed in a second half along the longitudinal direction of the housing. 
     
     
         9 . The mobile terminal according to  claim 8 , wherein the camera is placed in the second half of the housing. 
     
     
         10 . The mobile terminal according to  claim 9 , wherein the circuit board is placed in the second half of the housing. 
     
     
         11 . A mobile terminal comprising:
 a housing;   a camera placed in the housing;   a circuit board included in the housing;   a charging coil arranged in the housing;   a wireless communication coil electrically isolated from the charging coil; and   a magnetic sheet including a front surface, on which the charging coil and the wireless communication coil are arranged, and a back surface; wherein
 the charging coil includes a first winding portion, a first leg portion, and a second leg portion, 
 the wireless communication coil includes a second winding portion, 
 the first and second leg portions of the charging coil are arranged between the second winding portion of the wireless communication coil and the back surface of the magnetic sheet, and 
 the first and second leg portions extend from the first winding portion toward a side where the camera is placed. 
   
     
     
         12 . The mobile terminal according to  claim 11 , wherein the first winding portion of the charging coil has an internal dimension spanning at least 15.5 mm. 
     
     
         13 . The mobile terminal according to  claim 11 , wherein the first winding portion of the charging coil defines an internal hollow portion sized to receive a circle having a diameter of 15.5 mm. 
     
     
         14 . The mobile terminal according to  claim 11 , wherein the first winding portion of the charging coil is wound in a shape selected from a rectangular shape, an oblong shape, a circular shape, an elliptical shape, and a polygonal shape. 
     
     
         15 . The mobile terminal according to  claim 11 , wherein the first winding portion of the charging coil is wound in a circular shape and an internal diameter of the circular shape is greater than 15.5 mm. 
     
     
         16 . The mobile terminal according to  claim 11 , wherein the second winding portion of the wireless communication coil is wound in a shape selected from a rectangular shape, a circular shape, a square shape, and a polygonal shape.
