Abstract
A speaker unit with a speaker frame and two opposing membranes each being arranged to move up and down along a main speaker axis. Two drive units are present for each membrane, having a driver static part and a driver moving part. A sealing edge suspension is connected to a perimeter of the associated membrane and to the major front surface and major back surface of the speaker unit, respectively. For each driver moving part, a spider arm suspension is present for suspending the driver moving part to the speaker frame in a flexible manner. The sealing edge suspension is at least partially positioned above the associated drive units when viewed in a direction parallel to the main speaker axis.
Claims16
A transducer assembly comprising:
- a frame having a first surface, an opposing second surface, and an axis (A) extending therethrough, wherein the first surface and the second surface define a first aperture and a second aperture, respectively;
- first and second membranes arranged in the first and second aperture, respectively;
- a first suspension element resiliently coupling the first membrane to the first surface;
- a second suspension element resiliently coupling the second membrane to the second surface;
- and
- three drive units for each of the first and second membranes, each drive unit comprising a driver static part and a driver moving part, wherein the three drive units for each of the first and second membranes are positioned equidistantly from the axis (A) and are equiangularly positioned at 120-degree intervals around the axis (A);
- wherein the driver moving parts of the three drive units for each of the first and second membranes are physically coupled to their respective membrane via a single, unified connection member that spans between the three drive units and the respective membrane.
