A hardwaresoftware system and method that collectively enables virtualization of the host computer’s native IO system architecture via the Internet and LANs. Furthermore, a face plate, a control circuit board, a drive circuit board, the heat dissipating fins, a fan and a ventilation plate are separately series-connected in alignment and fitted on a base thereof. Also, a high insensitivity to misalignment of one of the intracavity ring optics is achieved without having to suffer any deleterious effects associated with the high intensity of radiation normally encountered at an intracavity focal plane. Users may select or create their sounds message andor person sound identifiers. Therefore, first light beams generated by the first light-emitting elements are projected onto the hollow light-guiding body, and the first light beams are guided by the hollow light-guiding body and are reflected by the reflecting layer in order to make the hollow light-guiding body generate the annular illumination effect.
