Abstract: A wearable device comprises a main body and at least one belt. The main body comprises a casing, and the casing comprises at least one first engaging member and at least one first positioning member. The at least one belt comprises a connecting portion and an adapter. The adapter is connected to the connection portion of the at least one belt, and comprises at least one second engaging member and at least one second positioning member. The at least one first positioning member is connected to the at least one second positioning member correspondingly for positioning the belt on the main body. The at least one first engaging member is engaged with the at least one second engaging member correspondingly, so that the belt is fixed to the main body. Consequently, the main body and the belt connect to each other firmly and are easy to be assembled and disassembled.

Abstract: An electronic device including a casing, a printed circuit board, a contact spring and a connector is provided. The printed circuit board is disposed in the casing, and the contact spring is electrically connected to and located on the printed circuit board. The connector is movably disposed at the casing, and a part of the connector is protruded from the casing. While the connector is pressed by external force, the connector is moved to contact the contact spring so as to conduct with the printed circuit board.

Abstract: A wearable device includes a host and plural functional modules. The host includes a first housing and a controlling unit. The controlling unit includes a first electrical conduction part and a second electrical conduction part. Each functional module is capable of detachable coupling with the host. Every two adjacent functional modules are detachably coupled with each other. Each functional module includes a second housing, a functional circuit unit and a connection unit. The functional circuit unit includes a third electrical conduction part and a fourth electrical conduction part. The connection unit includes a first connection part and a second connection part. The first connection part is connected with the third electrical conduction part. The second connection part is selectively connected with the first electrical conduction part, the second electrical conduction part of the host or the fourth electrical conduction part of the adjacent function module.
