    Abstract: PURPOSE: A sound device using air pressure is provided to provide a speaker unit to generate sound using an actuator. CONSTITUTION: A driving unit(100) moves in one direction. A unit(200) changes a cross section area for air discharge corresponding to motion of the driving unit. A container(300) generates sound by discharging internal air to the outside depending on the cross section area for air discharge. The driving unit comprises a permanent magnet and a coil. The driving unit vertically moves in one direction according to a direction of force applied to the coil. A cross section of the unit is formed in a letter L shape. One side of the letter L shape changes the cross section area for air discharge. The inside of the container maintains relatively high pressure against an external environment.

    Abstract: PURPOSE: A cooling device for a mobile electronic device and a mobile electronic device are provided to prevent a user from getting burned due to the heat generated from the mobile electronic device. CONSTITUTION: A heat sink(200) absorbs the heat generated from the mobile electronic device. If the temperature of the heat sink is higher than a melting point of a phase change material(300), the phase change material changes form a solid to a liquid. The phase change temperature of the phase change material is arbitrarily selected. The heat sink is attached and detached to/from the heating system of the mobile electronic device.
