Abstract

A controlling assembly is disclosed, which is adapted to be disposed at a casing, in which the casing has an opening. The controlling assembly includes an infrared transmission module (IR transmission module), a pressing switch and a button. The IR transmission module is adapted to be disposed in the casing and corresponding to the opening. The pressing switch is adapted to be disposed in the casing. The button is adapted to be movably disposed on the casing and shield the opening, in which the button has transparency. The IR transmission module is adapted to transmit or receive infrared light via the opening and passing through the button and the pressing switch is able to be triggered by pressing the button. The invention also discloses an electronic device which includes a casing and a controlling assembly.

Claims

1. A controlling assembly, adapted to be disposed at a casing, wherein the casing has an opening;

the controlling assembly comprising;

an infrared transmission module, adapted to be disposed in the casing and corresponding to the opening;

a pressing switch, adapted to be disposed in the casing; and

a button, adapted to be movably disposed on the casing and shield the opening, wherein the button has transparency, the infrared transmission module is adapted to transmit or receive infrared light via the opening and passing through the button and the pressing switch is able to be triggered by pressing the button.

2. The controlling assembly as claimed in claim 1, further comprising:

a circuit board, adapted to be disposed in the casing, wherein the infrared transmission module and the pressing switch are disposed at the circuit board.

3. The controlling assembly as claimed in claim 2, wherein the circuit board has two side-surfaces opposite to each other, and the infrared transmission module and the pressing switch are respectively disposed at the two side-surfaces of the circuit board.

4. The controlling assembly as claimed in claim 2, wherein the circuit board has two side-surfaces opposite to each other, and the infrared transmission module and the pressing switch are disposed at one of the two side-surfaces of the circuit board.

5. The controlling assembly as claimed in claim 1, wherein the button has a pressing portion and a contacting portion, the pressing portion is adapted to be exposed at the casing and accept an external force, and when the pressing portion drives the contacting portion due to the pressing of the external force, the contacting portion triggers the pressing switch.

6. The controlling assembly as claimed in claim 5, wherein the button comprises a fixing end and a free end, the fixing end is fixed on the casing, the pressing portion and the contacting portion are located at the free end, and when the pressing portion drives the contacting portion due to the pressing of the external force, the free end is able to move relatively to the fixing end to make the contacting portion trigger the pressing switch.

7. The controlling assembly as claimed in claim 1, wherein portion of the button for shielding the opening is able to allow infrared light passing through but to block visible light.

8. An electronic device, comprising:

a casing, having an opening; and

a controlling assembly, disposed at the casing and comprising;

an infrared transmission module, disposed in the casing and corresponding to the opening;

a pressing switch, disposed in the casing; and

a button, movably disposed on the casing and shielding the opening, wherein the button has transparency, the infrared transmission module transmits or receives infrared light via the opening and passing through the button and the pressing switch is able to be triggered by pressing the button.

9. The electronic device as claimed in claim 8, wherein the controlling assembly further comprises a circuit board disposed in the casing, wherein the infrared transmission module and the pressing switch are disposed at the circuit board.

10. The electronic device as claimed in claim 9, wherein the circuit board has two side-surfaces opposite to each other, and the infrared transmission module and the pressing switch are respectively disposed at the two side-surfaces of the circuit board.

11. The electronic device as claimed in claim 9, wherein the circuit board has two side-surfaces opposite to each other, and the infrared transmission module and the pressing switch are disposed at one of the two side-surfaces of the circuit board.

12. The electronic device as claimed in claim 8, wherein the button has a pressing portion and a contacting portion, the pressing portion is exposed at the casing and adapted to accept an external force, and when the pressing portion drives the contacting portion due to the pressing of the external force, the contacting portion triggers the pressing switch.

13. The electronic device as claimed in claim 12, wherein the button comprises a fixing end and a free end, the fixing end is fixed on the casing, the pressing portion and the contacting portion are located at the free end, and when the pressing portion drives the contacting portion due to the pressing of the external force, the free end is able to move relatively to the fixing end to make the contacting portion trigger the pressing switch.

14. The electronic device as claimed in claim 8, wherein portion of the button for shielding the opening is able to allow infrared light passing through but to block visible light.
