Abstract | An electro-acoustic transducer includes a tubular body extending a longitudinal direction and having two end portions, opposing each other longitudinally, and internally having a first chamber, sending with the first end portion and a second chamber, on one side adjacent to and in fluidic communication with the first chamber and on the other side ending with the second end portion. The first end portion is closed towards the outside by a membrane applied to the tubular body. The second end portion has openings that put it in fluidic communication to the outside of the tubular body. The first chamber containing electrical windings arranged in succession to each other in the longitudinal direction. The second chamber is filled with a liquid. A movable element is housed in the first chamber and has a permanent magnets packaged and arranged one above the other, with the magnetization alternating and separated. |
