Abstract

The present invention provides a wearable device with wireless transmission. The wearable device includes: a first exterior member configured to operate at a first frequency band; a second exterior member configured to operate at a second frequency; and a connecting member configured to electrically insulate the first exterior member from the second exterior member, so the wearable device is able to operate at the first frequency band and the second frequency band simultaneously. A frame structure of the wearable device is formed by stacking the first exterior member, the connecting member and the second exterior member in sequence from top to bottom. In addition, a method for manufacturing the same is also provided in the present invention.
