1. Technical Field
The present disclosure relates to an electronic device with a button assembly.
2. Description of Related Art
Many electronic devices such as tablet computers include a physical button. Many button assemblies of different structures have been proposed. However, an electronic device including a new button assembly is still needed.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in 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 the several views.
Embodiments of the present disclosure will be described with reference to the accompanying drawings.
Referring to
The electronic device 100 further includes an internal frame 30, an elastic member 40, and a circuit board 50. The frame 30 includes a support portion 31 that is spaced apart from the inner side of the front panel 10, and two connecting portions 32 connected to opposite ends of the support portion 31. In the embodiment, the connecting portions 32 are secured to the inner side of the front panel 10 via adhesive tape. The support portion 31 and the front panel 10 cooperatively define a receiving space 33.
The elastic member 40 is received in the receiving space 33, and includes a main body 41 and two elastic arms 42 extending from main body 41. The main body 41 is received in a cavity 23 defined in the lower side of the button 20. In other embodiments, the cavity 23 may omitted, and the main body 41 may be directly secured to the lower side of the button 20. The ends of the elastic arms 42 are secured to the support portion 31 of the frame 30.
In the embodiment, the circuit board 50 is a flexible circuit board, and a portion of the circuit board 50 is secured to the support portion 31 and located in the receiving space 33. The circuit board 50 includes a switch 51 located in the receiving space 33 under the button 20.
When depressed, the button 20 moves down and actuates the switch 51. After the button 20 is released, the elastic member 40 rebounds and pushes the button 20 back to its original position.
While various embodiments have been described and illustrated, the disclosure is not to be construed as being limited thereto. Various modifications can be made to the embodiments by those skilled in the art without departing from the true spirit and scope of the present disclosure as defined by the appended claims.
