Abstract: A massage device includes a housing, and a first driving assembly, a second driving assembly, and a massage assembly received in the housing. The first driving assembly includes a first driving motor. The second driving assembly includes a second driving motor mounted to the housing, and a shaft handle mounted to the second driving motor and abutting against a bottom surface of the second end. The massage assembly includes a fixing frame and a massager received in the fixing frame. The fixing frame includes a first end pivotally connected to the housing and an opposite second end. The first driving motor can drive the massager reciprocally. The second driving motor can drive ends of the shaft handle to move circumferentially, thereby causing the second end to move back and forth perpendicular to the extending direction.

Abstract: A wireless location device comprises a BLUETOOTH beacon configured to emit wireless signals and an electromagnetic shielding cover. The BLUETOOTH beacon is positioned within the electromagnetic shielding cover. The electromagnetic shielding cover comprises an inner surface comprising a plurality of micro-structures, and an opening below the inner surface. The inner surface is configured to reflect towards the opening the wireless signals emitted by the BLUETOOTH beacon which are not directly emitted out of the opening.
