[0088] In step S220, the first processor 111 of the first electronic element 110 determines whether the second electronic element 120 is detached from the first electronic element 110. If so, the process proceeds step S230; if not, the process returns to step S220.

[0089] In step S230, as illustrated in FIG. 6A, the second electronic element 120 wirelessly communicates with the third electronic element 130 through the pairing information P1 in the third electronic element 130 when the when the second electronic element 120 disconnects with the third electronic element 130.

[0090] Furthermore, in the present embodiment, the second communication unit 122 of the second electronic element 120 and the third communication unit 132 of the third electronic element 130 establish the second wireless connection L2 when the when the second electronic element 120 disconnects with the third electronic element 130.

[0091] In step S240, the first processor 111 of the first electronic element 110 determines whether the second electronic element 120 is electrically connected with the first electronic element 110 again. If so, the process proceeds step S250; if not, the second electronic element 120 maintains communicating with the third electronic element 130.

[0092] In step S250, as illustrated in FIG. 6B, the second electronic element 120 disconnects with the third electronic element 130 when the second electronic element 120 is electrically connected with the first electronic element 110. Then, the process returns to step S220.

[0093] Furthermore, in the resent embodiment, the second wireless connection L2 is disconnected when the second electronic element 120 disconnects with the third electronic element 130.

[0094] Referring to FIG. 7A, FIG. 7A illustrates a diagram view of structure of the first electronic element 110 of FIG. 1A, and FIG. 7B illustrates a diagram view of the second electronic element 120 being disposed thin the concave portion 111r of FIG. 7A.

[0095] As illustrated in FIG. 7A, the first electronic element 110 is, for example, mouse, and the second electronic element 120 is, for example, earphone. The first electronic element 110 includes a casing 111 and a cover 112. The casing 111 has at least one concave portion 111r, wherein each second electronic element 120 is detachably disposed within the corresponding concave portion 111r. In the present embodiment, the concave portion 111r downwardly extends from an upper surface of the casing 111. In another embodiment, the concave portion 111r could upwardly extend from a bottom surface of the casing 111. In other embodiment, the concave portion 111r could laterally extend from a lateral surface of the casing 111.

[0096] As illustrated in FIG. 7B, the cover 112 is pivotally connected with the casing 111. The cover 112 could cover the second electronic element 120 disposed within the concave portion 111r.

[0097] As illustrated in FIG. 7A, the first electrode E11 and the second electrode E12 are disposed on a surface of the concave portion 111r of the casing 111, and the third electrode E21 and the fourth electrode E22 are disposed on the second electronic element 120. As illustrated in FIG. 7B, when the second electronic element 120 is disposed within the concave portion 111r, the first electrode E11 and the second electrode E12 of the first electronic element 110 are electrically connected with the third electrode E21 and the fourth electrode E22 of the second electronic element 120 respectively.

[0098] While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
