  • Mobile communication terminal
    Patent number: 7565184
    Abstract: A mobile communication terminal is provided with a speaker having a size suitable for music appreciation and is implemented without widening the mobile communication terminal or decreasing an area of a display. Furthermore, mixture between sound emitted toward a front side of the speaker and sound emitted toward a rear side of the speaker is prevented as is leakage of sound from the body of the mobile communication terminal.
