Abstract

A button assembly suitable for being disposed at an opening of a housing of a handheld electronic device is provided. The button assembling includes a button, a signal-receiving-and-transmitting component and a switch. The button is movably disposed at the opening, and the button has a pressing portion exposed by the housing. The signal-receiving-and-transmitting component is disposed in the housing and corresponds to the pressing portion, wherein the signal-receiving-and-transmitting component is suitable for transmitting or receiving a wireless signal passing through the pressing portion. The switch is disposed in the housing and coupled to the button, so that the switch is adapted to be actuated by pressing the pressing portion of the button. A handheld electronic device including a body, a housing and a button assembly is also provided. The housing covers the body and has an opening. The button assembly is disposed at the opening.

Claims

1. A button assembly, suitable for being disposed at an opening of a housing of a handheld electronic device, the button assembly comprising:

a button, movably disposed at the opening, and the button having a pressing portion exposed by the housing;

a signal-receiving-and-transmitting component, disposed in the housing and corresponding to the pressing portion, wherein the signal-receiving-and-transmitting component is suitable for transmitting or receiving a wireless signal passing through the pressing portion; and

a switch, disposed in the housing and coupled to the button, such that the switch is adapted to be actuated by pressing the pressing portion of the button.

2. The button assembly as claimed in claim 1, wherein the signal-receiving-and-transmitting component comprises an infrared-receiving-and-transmitting component.

3. The button assembly as claimed in claim 1, further comprising:

a first circuit board, disposed in the housing, wherein the signal-receiving-and-transmitting component is disposed on a first surface of the first circuit board.

4. The button assembly as claimed in claim 3, wherein the button has a containing space, the first circuit board is disposed in the containing space, and the first surface faces the pressing portion.

5. The button assembly as claimed in claim 4, wherein the switch is disposed on a second surface of the first circuit board, the second surface is opposite to the first surface, and the button exposes the switch.

6. The button assembly as claimed in claim 5, wherein the switch corresponds to a protrusion, and the protrusion is disposed in the housing and faces the opening.

7. The button assembly as claimed in claim 4, further comprising:

a second circuit board, disposed in the housing, wherein the switch disposed on a third surface of the second circuit board, and the third surface faces the button.

8. The button assembly as claimed in claim 7, further comprising:

a protrusion, disposed on a surface of the button inside the housing and corresponding to the switch.

9. The button assembly as claimed in claim 7, wherein the containing space is sealed, and the first circuit board and the signal-receiving-and-transmitting component are disposed in the containing space.

10. The button assembly as claimed in claim 9, further comprising:

a waterproof material, disposed at the opening and isolating the button and an inner space of the housing, wherein the button and the switch are respectively located at two opposing sides of the waterproof material.

11. The button assembly as claimed in claim 3, wherein the first circuit board is located outside of the button, and the signal-receiving-and-transmitting component and the switch are disposed on the first surface of the first circuit board.

12. The button assembly as claimed in claim 11, further comprising:

a protrusion, disposed on a surface of the button inside the housing and corresponding to the switch.

13. A handheld electronic device, comprising:
