The electronic device includes a housing, a magnet positioned within the housing, and an elastic body connected to the magnet. At least a portion of the elastic body changes a shape or a position thereof, in response to a change of a magnetic force of the magnet. ## Claims ### Claim 1 A portable electronic device comprising: a housing; a magnet device positioned within the housing; an elastic body including a fixing part and elastic parts formed at opposite ends of the fixing part, the elastic parts being formed to be inclined with respect to the fixing part and to provide an elastic force to the fixing part, wherein both ends of the elastic body are fixed to an inner face of the housing; a holder mounted to the fixing part and fixing the magnet device to the elastic body, wherein the magnet device is mounted on the fixing part of the elastic body while being fixed to the holder, wherein the elastic force provided by the elastic parts acts in a direction of causing the fixing part to be spaced apart from the inner face of the housing, and wherein at least a portion of the elastic body changes a shape or a position thereof and the fixing part comes in contact with the inner face of the housing, in response to a change of a magnetic force of the magnet device. ### Claim 2 (depends on 1) The portable electronic device of claim 1, wherein the fixing part and the fixing part moves from a first position corresponding to a first face of the housing to a second position corresponding to a second face of the housing, in response to the change of the magnetic force. ### Claim 3 (depends on 1) The portable electronic device of claim 1, further comprising a display. ### Claim 4 (depends on 3) The portable electronic device of claim 3, wherein the magnet device is disposed at an edge region of the housing. ### Claim 5 (depends on 1) The portable electronic device of claim 1, wherein the holder is configured to accommodate the magnet device. ### Claim 6 (depends on 5) The portable electronic device of claim 5, wherein the holder is formed of a material that is different from that of the elastic body. ### Claim 7 (depends on 1) The portable electronic device of claim 1, wherein the elastic body spaces the magnet device apart from a face of the housing, in response to the change of the magnetic force. ### Claim 8 (depends on 1) The portable electronic device of claim 1, wherein the housing comprises support protrusions that receive end portions of the elastic body. ### Claim 9 (depends on 1) The portable electronic device of claim 1, wherein the magnet device comprises a first magnet corresponding to a first polarity and a second magnet corresponding to a second polarity. ### Claim 10 (depends on 9) The portable electronic device of claim 9, wherein the first magnet and the second magnet are spaced apart from each other by a predetermined distance. ### Claim 11 (depends on 1) The portable electronic device of claim 1, wherein the magnet device comprises a first magnet and a second magnet corresponding to a same polarity. ### Claim 12 (depends on 11) The portable electronic device of claim 11, wherein the first magnet and the second magnet are spaced apart from each other by a predetermined distance. ### Claim 13 (depends on 1) The portable electronic device of claim 1, wherein the magnet device changes the position thereof, based on an elastic force of the elastic body. ### Claim 14 (depends on 1) The portable electronic device of claim 1, wherein the change of the magnetic force is caused by another magnet included in an external device. ### Claim 15 A portable electronic device comprising: a housing; a first magnet positioned within the housing; an elastic body including a fixing part and elastic parts formed at opposite ends of the fixing part, the elastic parts being formed to be inclined with respect to the fixing part and to provide an elastic force to the fixing part, wherein both ends of the elastic body are fixed to an inner face of the housing; and a holder mounted to the fixing part and fixing the first magnet to the elastic body, wherein the first magnet is mounted on the fixing part of the elastic body while being fixed to the holder, wherein the elastic force provided by the elastic parts acts in a direction of causing the fixing part to be spaced apart from the inner face of the housing, and wherein at least the fixing part of the elastic body is moveable between a first position spaced apart from the inner face of the housing and a second position and comes in contact with the inner face of the housing, in response to a change of a magnetic force of the first magnet. ### Claim 16 (depends on 15) The portable electronic device of claim 15, wherein the first magnet moves from the second position to the first position, based on the elastic force of the elastic body. ### Claim 17 (depends on 15) The portable electronic device of claim 15, further comprising an input/output device that comprises a second magnet, wherein the input/output device is attachable to and detachable from the housing based on the magnetic force of the first magnet and the second magnet. ### Claim 18 (depends on 17) The portable electronic device of claim 17, wherein the input/output device further comprises a second elastic body coupled to the second magnet. ### Claim 19 (depends on 17) The portable electronic device of claim 17, wherein the input/output device further comprises at least one of a display, a keyboard, a speaker, and a touch pad. ### Claim 20 A portable electronic device comprising: a housing; a magnet positioned within the housing; an elastic body including a fixing part and elastic parts formed at opposite ends of the fixing part, the elastic parts being formed to be inclined with respect to the fixing part and to provide an elastic force to the fixing part, wherein both ends of the elastic body are fixed to an inner face of the housing; and a holder mounted to the fixing part and fixing the magnet to the elastic body, wherein the magnet is mounted on the fixing part of the elastic body while being fixed to the holder, wherein at least the fixing part of the elastic body is spaced apart from the inner face of the housing by the elastic force of the elastic parts, and wherein at least the fixing part of the elastic body comes in contact with the inner face of the housing in response to a change of a magnetic force of the magnet.
