Abstract
The present invention is a mobile device having an improved roller feel, comprising a hollow metal cylinder, a support and a plurality of terminals disposed firmly on the support. The hollow metal cylinder comprises a plurality of interference areas at an end of the hollow metal cylinder. The support comprises two braces. The terminals comprises a plurality of spring contacts, where the terminals are in contact with the inner surface of the hollow metal cylinder and at least one of the spring contacts stretches into the hollow metal cylinder in a depth not exceeding the scope of the interference areas. When rolling the hollow metal cylinder, the present invention makes the spring contacts create explicit and regular stress variations to produce a sense of feel. The interactions between the hollow metal cylinder and the spring contacts are enhanced and the sense of feel is more obvious; and the effect of durability is improved.
