1. Technical Field
The present disclosure relates to wrist worn devices and, particularly, to an electronic wrist worn device able to receive user input.
2. Description of Related Art
Many wrist worn devices now boast multiple functions beyond traditional wrist watches. For example, wrist worn devices may include MP3, GPS, TV, and phone functions as well as time-telling. However, to be attractive to consumers the wrist worn device should be small, and so the use of touch screens may increase functionality but give rise to user error because of the cramped space of the screen and the number of icons needed for full functionality.
The components of the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout several views.
Embodiments of the present disclosure will now be described in detail below, with reference to the accompanying drawings.

Referring to
The rotatable ring 20 is a circular ring. A number of protrusions 201 protrude from the bottom surface 202 of the rotatable ring 20. In the embodiment, the number of the protrusions 201 is eight. The protrusions 201 are evenly spaced apart from each other around a rotating axis of the ring 20. The outer diameter of the rotatable ring 20 is the same as that of the case 30. The inner diameter of the rotatable ring 20 is larger than the distance between two hollow tubes 102. When the case 30 is assembled to the cover 10, the top surface 203 and the bottom surface 202 of the rotatable ring 20 respectively contact the cover 10 and the case 30. In addition, when the case 30 and the cover 10 are assembled together, a part of the rotatable ring 20 is external to the cover 10, allowing for turning by the user.
The case 30 includes two threaded posts 301 and a switch 302. The threaded posts 301 protrude from the top surface 303. The threaded post 301 can be screwed into the hollow tubes 102, to connect the cover 10 to the case 30.
In the embodiment, the switch 302 is arranged on the inner sidewall 304. In an alternative embodiment, the switch 302 may be arranged on the top surface 303. The switch 302 is arranged in such a manner that the protrusions 201 of the ring 20 can actuate and move over the switch 302. For ease of such movement between the switch 302 and the protrusions 201, each protrusion 201 has rounded side edges. When needed, each protrusion 201 can move together with the rotation of the rotatable ring 20 to a position to actuate the switch 302.

The case 30 includes two protruding posts 310 protruding from the top surface 303 of the case 30. The height of each protruding post 310 is greater than that of the case 30. The case 30 is connected to the cover 10 through the protruding posts 310. In the embodiment, the protruding posts 310 are capable of sticking to the cover 10.
The outer diameter of the rotatable ring 20 is the same as that of the case 30. The inner diameter of the rotatable ring 20 is longer than the distance between two protruding posts 310. When the cover 10 and the base 30 are assembled together, the bottom surface 202 of the rotatable ring 20 contacts the case 30. In addition, as mentioned above, a part of the rotatable ring 20 is external to the cover 10, allowing for turning by the user. As described in the first embodiment, when needed, each protrusion 201 can move together with the rotation of the rotatable ring 20 to a position to actuate the switch 302.
In the embodiments, when the switch 302 is actuated to generate a signal, the processor (not shown) of the wrist worn device 1 executes a preset function in response to the signal from the switch 302, such as controlling a cursor on the display unit 101 to move to the next menu.
In the embodiments, the case 30 further includes an enter button 305 and a return button 306 (see
Although the present disclosure has been specifically described on the basis of the exemplary embodiment thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiment without departing from the scope and spirit of the disclosure.
