Educational Effect of Nursing Process Exercises in Psychiatric Nursing, Using the Computer Assisted System for Learning

Abstract

An apparatus for securing a speaker to a portable computer including a speaker receiving recess adapted to receive a speaker therein and defined by an annular guide rib extending downwardly from a lower surface of a panel of a computer body, a speaker fixing member adapted to cover the speaker receiving recess, thereby upwardly supporting the speaker received in the speaker receiving recess, the speaker fixing member being coupled to the panel by a rotation thereof carried out in a selected left or right direction by a desired angle, and anti-loosening members each extending radially outwardly from the speaker fixing member, each of the anti-loosening members engaging with the lower surface of the panel in a state, in which it rotates in accordance with the rotation of the speaker fixing member, thereby preventing the speaker fixing member from rotating optionally from a state fixing the speaker fixing member. In this fixing device, the fixing of the speaker is achieved by simply rotating a speaker fixing member by a desired angle. No screw is used for the fixing of the speaker. Accordingly, it is possible to simply and conveniently achieve the speaker fixing process. It is also possible to completely avoid a sound trembling phenomenon due to vibrations occurring at coupling portions. Thus, a good quality of sound can be output. The disclosed speaker securing apparatus can be utilized in a desktop computer, portable computer, wall or shelf of a home or office, automobile interior panel, and in other appropriate panels and enclosures.
