Patent ID: 7961152

Claim:
An electronic device comprising: a helical resilient member arranged inside the electronic device, comprising a first end, a second end, and a predetermined number of turns of coil arranged between the first and second ends, the helical resilient member being made of an electrically conductive material, the predetermined number of turns of coil defining an electrical inductance; a wireless signal transmitting/receiving antenna provided for transmitting/receiving a wireless signal of a selected band, the wireless signal transmitting/receiving antenna comprising a signal feed point; a signal feeding line connected between the first end of the helical resilient member and the signal feed point of the wireless transmitting/receiving antenna; a wireless signal transmitting/receiving module comprising a first signal connection terminal and a second signal connection terminal, which are connected to the first and second ends of the helical resilient member so as to couple the inductance of the helical resilient member to the wireless signal transmitting/receiving module; a base portion comprising first and second edges, a locking slot being formed in a surface of the base portion at a location close to the second edge; a hinge mechanism arranged at the first edge of the base portion; an openable cover portion comprising a coupling edge and a latching edge, the coupling edge being connected to the first edge of the base portion by the hinge mechanism so that the cover portion is rotatable about the hinge mechanism with respect to the base portion for opening/closing the cover portion; and a latch mechanism arranged at the latching edge of the cover portion, comprising a movable latch plate, and at least one positioning plate for maintaining the latch plate at a predetermined position whereby when the cover portion is closed on the base portion, arranged such that the latch plate engages the locking slot defined in the base portion and the engagement between the latch plate and the locking slot is secured by a biasing force applied to the latch plate by the helical resilient member.
