An apparatus for preventing movement of dust in a guttural sound outlet of a speaker system is provided to prevent dust generated by vibration in operating a speaker by including a dust movement preventing unit in a guttural sound outlet of a speaker system. A case(12) includes a space part in which a guttural sound generated in a speaker is resonated. A fixing plate(14) is included between the case and a grille. The speaker(11) is inserted to at least one or more through-holes formed in the fixing plate. A guttural sound outlet is adjacent to the speaker, and is formed in the fixing plate. A dust movement preventing unit(300) is coupled in the guttural sound outlet by a coupling member in which a ground member and an anti-electrostatic filter are included. The coupling member has an elastic force. A coupling groove is formed inside an outer circumference of the coupling member. The ground member inserted between both sides of the anti-electrostatic filter is inserted to the coupling groove by the elastic force of the outer circumference. |
