<p>Device in acoustic transmitters comprising an elastic tubular shell (1), such as a diaphragm, at least one driving member arranged inside said shell for generating an oscillating movement of the shell, and pressure rods (5,6) arranged inside the shell and in the axial direction for transmitting the movement of the driving member to the shell. According to the invention the driving member comprises a body (6) with opposite recesses (13,14,15) into which driving rods (16,17,18) are inserted. One end of each driving rod is attached to a respective pressure rod (4,5) which directly influence the shell (1), and the other end of each driving rod makes contact with the bottom of the respective recess.</p> |
