Abstract
A novel diaphragm assembly, transducer and manufacturing method is here in proposed making use of a diaphragm assembly including a diaphragm having a first diaphragm component and a second diaphragm component. Both diaphragm components extend between respective inner perimeter and outer rim. The outer rim of the first diaphragm component overlaps with and is attached to the second diaphragm component at an overlap section. A voice coil assembly is connected to the inner perimeter of the second diaphragm component.
Claims23
A diaphragm assembly comprising:
- a diaphragm comprising:
- a first diaphragm component extending between an inner perimeter and an outer rim, and
- a second diaphragm component extending between an inner perimeter and an outer rim, wherein
- the outer rim of the first diaphragm component overlaps the second diaphragm component over an overlap section and wherein the second diaphragm component is attached to the first diaphragm component at the overlap section, and
- a voice coil assembly connected to the inner perimeter of the second diaphragm component of the diaphragm.
A loudspeaker transducer comprising a diaphragm assembly which comprises:
- a diaphragm comprising:
- a first diaphragm component extending between an inner perimeter and an outer rim, and
- a second diaphragm component extending between an inner perimeter and an outer rim, wherein
- the outer rim of the first diaphragm component overlaps the second diaphragm component over an overlap section and wherein the second diaphragm component is attached to the first diaphragm component at the overlap section, and
- a voice coil assembly connected to the inner perimeter of the second diaphragm component of the diaphragm.
A method for manufacturing the loudspeaker diaphragm assembly of a transducer, the method comprising:
- inserting a voice coil gauge inside a voice coil former,
- inserting the voice coil with the gauge to an air gap,
- attaching the voice coil to the inner perimeter of a second diaphragm component,
- removing the voice coil gauge, and
- attaching a first diaphragm component to the second diaphragm component at an overlap section.
