PURPOSE: A speaker for a system wiring pipe is provided to be installed quickly and effectively by being connected with a monitoring camera and lighting using a system wiring pipe. CONSTITUTION: An upper main body (10) forms elastic holders (11,11') on a curved surface protruded along a longitudinal direction in an upper surface and protrudes hooking steps (12,12') at both lower sides. A lower mesh (20) forms curved parts (21,21') which are bent to an inner side in a leading end. Side finishing bodies (30,30') form an insertion recess (31) at a side and form a hooking recess (32) in a middle portion of the insertion recess. A top main body fixes a speaker unit (40) on a bottom surface. In a state in which a mid compression chamber (20) is closely contacted to the lower side of the top main body, the side finishing body is combined to the both side ends of the mid compression chamber and top main body. The top main body is mounted at an extruded main body for a system wiring pipe by using the elastic holders. The extruded main body for a system wiring pipe forms a holding curved part at the lower part and forms an inserting unit at middle part of the holding curved part. |
