The application relates to the technical field of wearable devices, and discloses a smart ring and a wearable device set. The smart ring is worn on a finger of a user, and the smart ring comprises a shell, a housing cavity formed around a first axis, an electric core arranged in the housing cavity, and a circuit
assembly arranged in the housing cavity and electrically connected with the electric core. The circuit
assembly comprises a touch control module, and the touch control module comprises a
touch panel arranged in the circumferential direction of the shell. In the radial direction of the shell, the electric core and at least part of the
touch panel are stacked. The smart ring can solve the circumferential parallel
layout mode of the electric core and the touch control module in the prior art, has become a problem restricting the function expansion and wearing comfort of the smart ring, breaks through the circumferential size limitation of the annular space, and realizes efficient stacking and space
multiplexing of the functional modules.
