This study investigates life and damage due to structural and fatigue load at speaker placer with wall hanger type. As the small stress and deformation are shown at the models of A, B and C shapes on structural analysis, there is no problem at installing speaker placer. As the largest stress is happened at the middle part of joint on the models of A, B and C shapes, this part must be considered at the design. A shape is thought to have most fatigue damage among 3 shape models. C shape model has most excellent, but A model has least at fatigue durability. This study result is applied with the design of speaker placer and it can be useful at predicting prevention and durability against its damage.

This study is a technology related to a lighting lamp that illuminates indoor or outdoor lighting with light. In more detail, a see-through window is created in all directions on a case constituting the exterior, and a jade stone processed in a thin panel form is attached to the see-through window. By constructing a lighting lamp, since the soft light is irradiated indoors or outdoors through the jade stone, it provides comfort and warmth to the user, enhances the indoor or outdoor interior effect, emits far-infrared rays and negative ions, and emits a subtle floral scent It is a technology for lighting lamps using jade stones that emit. The characteristics of the product of this research and development is that the viewing window is formed in all directions on the case constituting the exterior, and the lighting lamp is composed by attaching the processed jade stone in the form of a thin panel to the viewing window. It is meaningful that they studied lightings using jade stones that generate sounds such as Buddhist scriptures, the Bible, and Sijo.

In recent years, with the focus on the younger generation, a minimal life that pursues a simple and light life has attracted attention, and a product that occupies a small space and has high practicality attracts attention. Therefore, a lot of studies on small but realistic products are going on by combining plural products into one. In this study, we developed a smart stand that can save space on the desk. The stand is equipped with a smartphone holder, humidifier, negative ion generator, and speaker functions. Because of this study, it is expected that the efficiency of space and economy will be improved in a small house of one person.
