Button assembly

1. A button assembly, comprising:

a first-button assembly, comprising a first button, and a first-mounting frame defining a void therein with edges of the first-mounting frame surrounding the first button therein, the first-mounting frame comprising a plurality of latching poles projecting therefrom, the first-button assembly further comprising a plurality of first-supporting arms extending from the first-mounting frame and connecting with the first button for holding the first button in the void;

a second-button assembly, the second-button assembly comprising a second-mounting frame defining a void therein, the second-mounting frame comprising a plurality of latching holes to cooperate with the latching poles for fixing the first-button assembly with the second-button assembly, the second-button assembly further comprising a plurality of second buttons extending from the second-mounting frame into the void of the second frame;

wherein the first-button assembly is attached to a back of the second-button assembly with the first button passing through the void of the second-mounting frame and protruding among the second buttons.

2. The button assembly as claimed in claim 1 , wherein each of the latching poles comprises a latching block formed thereon, the second-supporting frame further defining a slot adjacent to and communicating with each latching hole for receiving the corresponding latching block.

3. The button assembly as claimed in claim 2 , wherein the second-button assembly further defines a plurality of gaps between every two neighboring second buttons, and the first-supporting arms are formed correspondingly to the gaps as shelters of the gaps.

4. The button assembly as claimed in claim 1 , wherein the first-supporting arms comprise a flat portion fixed to the first button, and an oblique portion connecting the first-supporting frame with the flat portion.

5. The button assembly as claimed in claim 1 , wherein the second-supporting frame comprises a plurality of second-supporting arms and a second-mounting frame, each of the second-supporting arms extends from the second-mounting frame and are fixed to an adjacent one of the second buttons.

6. The button assembly as claimed in claim 5 , wherein the second-mounting frame is thicker than the second-supporting arms.

7. An electronic product, comprising:

a front cover, comprising an opening;

a circuit board, fixed with the front cover;

a button assembly, comprising a first-button assembly fixed with the front cover, and a second-button assembly, the first-button assembly comprising a first button, and a first-supporting frame used for supporting the first button, the first-supporting frame comprising a plurality of latching poles projecting therefrom, the second-button assembly comprising a plurality of second buttons arranged around the first button, and a second-supporting frame used for supporting the second buttons, the second-supporting frame comprising a plurality of latching holes for receiving the latching poles; and

wherein the button assembly is fixed between the front cover and the circuit board, and the first button and the second buttons are received in the opening of the front cover.

8. The electronic product as claimed in claim 7 , wherein the second-mounting frame comprises a plurality of mounting poles abutting against the first-mounting frame, and the latching holes are respectively formed in the mounting poles.

9. The electronic product as claimed in claim 7 , wherein each of the latching poles comprises a latching block formed thereon, the second-supporting frame further defining a slot adjacent to and communicating with each latching hole for receiving the corresponding latching block.

10. The electronic product as claimed in claim 7 , wherein the first-supporting frame further comprises a first-mounting frame, and a plurality of first-supporting arms respectively extending from the first-mounting frame and fixed to the first button.

11. The electronic product as claimed in claim 10 , wherein the second-button assembly further defines a plurality of gaps between every two adjacent second buttons.

12. The electronic product as claimed in claim 11 , wherein the first-supporting arms are configured to correspond to the gaps.

13. The electronic product as claimed in claim 10 , wherein the first-supporting arms comprise a flat portion fixed to the first button, and an oblique portion connecting the first-supporting frame with the flat portion.

14. The electronic product as claimed in claim 7 , wherein the second-supporting frame comprises a plurality of second-supporting arms and a second-mounting frame, each of the second-supporting arms extend from the second-mounting frame and are fixed to the corresponding second button.

15. The electronic product as claimed in claim 14 , wherein the second-mounting frame is thicker than the second-supporting arms.
