1. A back cover releasing mechanism for a mobile device, comprising: an elongated side key comprising a first end and a second end, configured to be mounted on a side of the mobile device such that a longitude direction of the side key is parallel with the side of the mobile device, wherein the side
1. A back cover releasing mechanism for a mobile device, comprising: an elongated side key comprising a first end and a second end, configured to be mounted on a side of the mobile device such that a longitude direction of the side key is parallel with the side of the mobile device, wherein the side key is a multifunction key configured such that pressing of the first end causes performance of a first function and pressing of the second end causes performance of a second function;a sliding member comprising a base portion configured to be coupled to the side key, and a latch portion, wherein the latch portion is configured to engage a back cover of the mobile device; anda spring member configured to be provided with a pre-load so as to hold the sliding member against the side key,wherein the back cover releasing mechanism comprises at least one of the following configurations: (a) the spring member is configured to be positioned at an opposite side of the latch portion from the side key;(b) the spring member is configured to be positioned at an opposite end of the base portion from the side key; or(c) the side key is configured with a dent at its central area, wherein the dent in the central area is stiffer than the first and second ends of the side key;andwherein the latch portion is also configured to be disengaged from the back cover of the mobile device if the first end and the second end of the side key are both pressed toward interior of the mobile device and the base portion of the sliding member is forced to move toward the interior of the mobile device and wherein when only one of the first end and the second end of the side key is pressed toward the interior of the mobile device, the latch portion is not disengaged from the back cover. 2. The back cover releasing mechanism according to claim 1, further comprising one or more elastic members between the back cover and a main body of the mobile device, configured to be positioned close to the sliding member, wherein in response to the latch portion of the sliding member being disengaged from the back cover, at least a part of the back cover springs away from the main body by force from the one or more elastic members. 3. The back cover releasing mechanism according to claim 1, wherein the side key is configured to be flexible-connected with the back cover. 4. The back cover releasing mechanism according to claim 1, wherein the side key is a volume key of the mobile device. 5. The back cover releasing mechanism according to claim 1, wherein an end of the latch portion extends toward the side key. 6. The back cover releasing mechanism according to claim 1, wherein an end of the latch portion extends parallel to the longitude direction of the side key. 7. The back cover releasing mechanism according to claim 1, wherein a force for pressing the first end and the second end of the side key together ranges from 10 newton to 20 newton, and a distance that the side key moves due to the press ranges from 0.3 mm to 1 cm. 8. The back cover releasing mechanism according to claim 1, wherein a force for pressing either of the first end and the second end of the side key is less than 10 newton, and a distance that the pressed end of the side key moves due to the press ranges from 0.1 mm to 0.5 mm. 9. The back cover releasing mechanism according to claim 1, wherein the latch portion is a hook. 10. The back cover according to claim 9, wherein the profile portion is configured to be in proximity to the latch portion and extends opposite to the extending direction of the latch portion. 11. A back cover of a mobile device, comprising a profile portion forming on its inner side, configured to detachably engage the latch portion of the sliding member of the back cover releasing mechanism according to claim 1. 12. A mobile device, comprising a back cover releasing mechanism according to claim 1, a back cover comprising a profile portion forming on its inner side, configured to detachably engage the latch portion of the sliding member of the back cover releasing mechanism, a flexible printed wiring circuit board for generating electronic signals. 13. The back cover releasing mechanism according to claim 1, wherein in an instance one of the first end or second end of the side key is pressed, the sliding member functions as a pivot for the side key. 14. The back cover releasing mechanism according to claim 1, wherein in an instance one of the first end or second end of the side key is pressed, a flexible connection associated with the pressed first end or second end is distorted and a flexible connection associated with the other of the first end or second end is undistorted. 15. The back cover releasing mechanism according to claim 1, wherein the side key is configured such that pressing of the first end causes an increase in volume and pressing of the second end causes a decrease in the volume. 16. The back cover releasing mechanism according to claim 1, wherein in an instance one of the first end or second end of the side key is pressed, a plunger associated with the pressed first end or second end is compressed so as to trigger related circuits. 17. An apparatus comprising a back cover releasing mechanism, wherein the back cover releasing mechanism comprises: an elongated side key comprising a first end and a second end, where the elongated side key is configured to be mounted on a side of a mobile device such that a longitude direction of the side key is parallel with the a side of the mobile device, wherein the side key is a multifunction key configured such that pressing of the first end causes performance of a first function and pressing of the second end causes performance of a second function; a sliding member comprising a base portion coupled to the side key, and a latch portion, wherein the latch portion is configured to engage a back cover of the mobile device, anda spring member configured to be provided with a pre-load so as to hold the sliding member against the side key,wherein the back cover releasing mechanism comprises at least one of the following configurations:(a) the spring member is configured to be positioned at an opposite side of the latch portion from the side key;(b) the spring member is configured to be positioned at an opposite end of the base portion from the side key; or(c) the side key is configured with a dent at its central area, wherein the dent in the central area is stiffer than the first and second ends of the side key;and where the latch portion is configured to disengage from the back cover of the mobile device when the first end and the second end of the side key are both pressed toward an interior of the mobile device and when the base portion of the sliding member is forced to move toward the interior of the mobile device and wherein when only one of the first end and the second end of the side key is reused toward the interior of the mobile device, the latch portion is not disengaged from the hack cover. 18.
