Loudspeaker mounting mechanism

This invention provides a spring loaded mounting mechanism for easily mounting and removing a loudspeaker housing within an opening in a surface. The mounting mechanism includes a shaft connected to the loudspeaker housing. Attached to the shaft is a spring actuated arm. The actuated arm is compressed inward toward the housing by the side walls of the surface surrounding the opening when the housing is being positioned within the opening. At a certain point when the housing is inserted far enough into the opening, the actuated arm will lose contact with the side walls of the surface surrounding the opening and will expand to its open position. In its open position, the arm is positioned just behind or against the back face of the surface surrounding the opening, locking the housing into the opening in the surface. The invention further allows for the spring actuated arm to be tightened against or moved away from the back face of the surface by adjusting the positioning of the shaft. To remove the housing from the opening, the spring actuated arm may be moved away from the back face of the surface surrounding the opening by compressing the arm inward toward the housing. The arm may be compressed inward through the use of a device or by the hand of a user. Once the arm is compressed inward, the housing may be easily removed from the opening.

Precise positioning platform with six freedom of motion

The invention provides a 6 degree of freedom precision positioning platform which is used for bearing objects and adjusting the position of a suction bed plate within the scope of the 6 degree of freedom. The 6 degree of freedom precision positioning platform comprises a horizontal adjustment platform and a vertical adjustment platform, wherein, the horizontal adjustment platform can be used for adjusting the position of the suction bed in the directions of an X axis, a Y axis and a Theta z axis, comprising a horizontal output platform which is fixedly connected with the suction bed and is used for bearing the suction bed, three groups of revolute pair flexible articulated mechanisms which are distributed evenly along a circumference and a horizontal base which is connected with the horizontal output platform by the revolute pair flexible articulated mechanisms. The vertical adjustment platform comprises three groups of adjustment mechanisms which are evenly distributed along the circumference and are used for adjusting the position of the suction bed in the directions of a Z axis, a Theta X axis and a Theta y axis. In the invention, the horizontal adjustment platform and the vertical adjustment platform are connected only by a cuniform mechanism and a vertical flexible spring, thus simplifying the structure of the positioning platform, reducing manufacturing difficulty and improving assembly accuracy.
