More Information
Summary:A resonance structure for improving a speaker sound of a portable terminal is provided to form more improved sound pressure by using metal-made case frame and sound insulation materials even though the same speaker devices are applied in speaker phone mode, thereby outputting high-quality voices and sounds. A lower metal case frame is equipped with a certain space inside by being combined with an upper metal case frame(121). At least one of speaker devices(21,22) is mounted on a portion of spaces formed by the upper and lower metal case frames. Sound insulation materials(31,32,33) of certain thickness form certain sound pressure of speaker sounds emitted from the speaker devices, by being installed to surround the speaker devices.
