Abstract: An installer is installed in a hole in a ceiling or a wall and includes a speaker frame and two connective units. The speaker frame may fix down a speaker and has a circumferential edge. The two connective units are provided on the speaker frame and either connective unit has a connective flexible strip, which may contract or expand laterally by moving in the longitudinal direction. First, as the two connective flexible strips contract inwardly in the radial direction, the speaker may be allowed to pass and then be placed in the hole. Then, as the two connective flexible strips expand outwardly in the radial direction, the diameter formed by the two connective units is larger than that of the hole. Now, the outer layer of a wall or a ceiling is sandwiched in between the circumferential edge and the two connective flexible strips.
