Patent Application
20200211794
The subject matter herein generally relates to button assemblies, and more particularly to a button assembly having a noise reduction structure.
Generally, keyboards of computers, laptops, and other electronic devices generate noise when keys of the keyboard are pressed. Such noise may disturb others in an office environment or in public spaces.
Implementations of the present disclosure will now be described, by way of embodiments, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. Additionally, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.
The electronic device 100 includes a display screen 21, a keyboard 22, and a connecting device 23. The display screen 21 and the keyboard 22 are coupled together by the connecting device 23.
Referring to
The buffer portion 152 is mounted to the extension portion 151 or the abutting portion 153 by an adhesive.
The buffer portion 152 is made of rubber, latex, styrofoam, foam, or EPE.
A cross-sectional shape of the buffer portion 152 may be triangular, round, quadrangular, semicircular, trapezoidal, or other shape. As shown in
The first buffer portion 1521 is mounted to the extension portion 151 by an adhesive, and the second buffer portion 1522 is mounted to the abutting portion 153 by an adhesive.
As shown in
Since the cross-sectional shape of the buffer portion 152 is triangular, round, quadrangular, semicircular, trapezoidal, or other shape, a contact area between the extension portion 151 and the abutting portion 153 is reduced. Thus, the buffer portion 152 has a damping effect to reduce noise generated between the extension portion 151 and the abutting portion 153 when the elastic piece 13 restores the keycap after being pressed.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
