A push-in in-ceiling speaker mount has multiple fastening units 1 mounted on an in-ceiling speaker 70. Each fastening unit 1 has a base frame 10, a torsion spring 20 securely mounted on the base frame 10, a pivoting member 30 pivotally mounted on the base frame 10, a slider plate 40 longitudinally movable on the base frame 10, and a spring holder 50 receiving the torsion spring 20, pivotally mounted on the base frame 10 and blocked by the pivoting member 30. When the speaker mount is moved upwardly through a ceiling, the underside of the ceiling holds a ceiling support 42 on the slider plate 40, and so the pivoting member 30 is pushed and pivoted. After being unblocked from the pivoting member 30, the spring holder (50) is pivoted outwardly to hold the topside of the ceiling in completion of the easy mounting of the speaker mount. |
