摘要： A low temperature sinterable dielectric ceramic composition and a multilayer ceramic chip capacitor. The dielectric ceramic composition is expressed by the general formula: aBaTiO3-bMgCO3-cY2O3-dCr2O3-eV2O5-f(xZrO2-y(K,Li)2O-zSiO2) (x+y+z=1; 0.05≦x≦0.18, 0.01≦y≦0.08, and 0.7.4≦z≦0.93); in which a, b, c, d, e and f are molar ratios; a=100, 1.0≦b≦2.0, 0.2≦c≦2.0, 0.02≦d≦0.3, 0.02≦e≦0.3, and 0.5≦f

摘要： The present invention relates to a portable terminal having retractable speakers that can be used by extending outwards to both sides of the portable terminal. The portable terminal includes a main body, at least one speaker, and a hinge unit. The main body has at least one display unit arranged on a first surface of the main body and a recess formed on a second surface of the main body opposite to the first surface. The speaker is retracted into the recess. The hinge unit is arranged at an edge of the recess to connect the speaker to the main body, to extend the speaker outwards from the recess, and to retract the speaker into the recess. The speaker outputs a sound outwards from the first surface of the main body when extended. The slope angle of the speaker can be adjusted by rotating the speaker about an axis of the hinge unit when extended.
