1. Technical Field
This exemplary disclosure generally relates to a stylus for a portable electronic device.
2. Description of related art
It is well-known that a variety of electronic devices include a touch panel. Examples of such electronic devices include smart phones, personal digital assistants (PDA), pagers, personal organizers, and the like. These devices typically include a display module under the touch panel. The display module generates target images associated with menu options, programs, user choices, and other operations. The user controls the device by pressing the touch panel over the target image with a stylus. However, typical styluses have complex structures and cannot be used on electrostatic capacitance type touch panels.
Therefore, there is room for improvement within the art.
Many aspects of the exemplary stylus for a portable electronic device 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 stylus. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views, in which:
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to
The connecting element 20 is for pivotably connecting the touch nib 30 to the blocks 13 of the main body 10. A diameter of the connecting element 20 is substantially equal to the receiving holes 131. In the exemplary embodiment, the connecting element 20 is a cylindrical shaft and is made of conductive materials, e.g. metal or conductive plastics.
The touch nib 30 includes a contacting portion 33 and a knuckle portion 31 perpendicularly projecting from one surface of the contacting portion 33. The other surface of the contacting portion 33 is a flat or planar contacting surface 331. When the nib 30 is pressed to slide along the touch panel 200, the contacting surface 331 touches the touch panel 200. Because the contacting surface 331 is flat, unlike pointed-tip styluses, there is no sharp or pointed tip to press the touch panel 200 with a highly concentrated tip force or pressure. In other words, the current flat contacting surface 331 applies less pressure to the touch panel 200 than traditional pointed styluses. A through hole 311 is defined in the knuckle portion 31. The through hole 311 allows the connecting element 20 to extend through. In the exemplary embodiment, the touch nib 30 is made of conductive materials, e.g. metal or conductive plastics.
During assembly, the through hole 311 is aligned with the receiving holes 131 of the main body 10. The connecting element 20 is inserted into the through hole 311 and receiving hole 131 to connect the touch nib 30 to the main body 10. The distal end of the block 13 resists the touch nib 30. Thus, the stylus 100 is assembled. In the exemplary embodiment, the connecting element 20 may be further fixed to the blocks 13 by means of soldering or laser welding for example.
Referring to
Since the main body 10, the connecting element 20, and the touch nib 30 are all made of conductive materials, when the touch nib 30 slides on the touch panel 200, the touch panel 200 generates current changes for the portable electronic device. The touch panel 200 is not directly touched by the user's finger so that the temperature of the panel 200 will not be affected by the user thus preventing false input.
It is to be understood that the connecting element 20 can be replaced by a hinge. Furthermore, the main body 10, the connecting element 20, and the touch nib 30 can be made of dielectric materials and a layer of conductive materials coated thereon by plating.
Referring to
The exemplary embodiment to the stylus 100 includes just a few components and the angle between the contacting surface 331 and the main body 10 can be adjusted, thus, the stylus 100 is easy to manufacture and use.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the disclosure.
