Distributed transducer suspension cones (DTSC)
A speaker device ( 1 ) having a frame ( 2 ), two opposite directed diaphragms ( 3, 3 ′), and two speaker drivers, each having at least one magnetic driver ( 10, 10 ′) for driving the two opposite directed diaphragms ( 3, 3 ′) in operation. A speaker damper ( 5, 5 ′) is associated with each of the two opposite directed diaphragms ( 3, 3 ′), and has a coil bracket ( 4, 4 ′) arranged to be driven by the associated at least one magnetic driver ( 10, 10 ′), a diaphragm connection member ( 6, 6 ′) arranged to fixedly attach the diaphragm ( 3, 3 ′) to the speaker damper ( 5, 5 ′), and a damper frame connection member ( 8, 8 ′) arranged to fixate the speaker damper ( 5, 5 ′) to the frame ( 2 ). The speaker damper ( 5, 5 ′) further comprises a damper leg member ( 7, 7 ′) arranged between the diaphragm connection member ( 6, 6 ′) and the damper frame connection member ( 8, 8 ′).
1. A speaker device comprising a frame, two opposite directed diaphragms, and two speaker drivers, each having at least one magnetic driver for driving the two opposite directed diaphragms in operation, further comprising
a speaker damper associated with each of the two opposite directed diaphragms,
the speaker damper comprising a coil bracket arranged to be driven by the associated at least one magnetic driver, a diaphragm connection member arranged to fixedly attach the diaphragm to the speaker damper, and a damper frame connection member arranged to fixate the speaker damper to the frame,
the speaker damper further comprising a damper leg member arranged between the diaphragm connection member and the damper frame connection member.
2. The speaker device according to claim 1 , wherein the damper leg member comprises a resilient material.
3. The speaker device according to claim 1 , wherein the damper leg member is a flat strip.
4. The speaker device according to claim 1 , wherein the damper leg member has a length which is greater than a shortest distance between the coil bracket and damper frame connection member.
5. The speaker device according to claim 1 , wherein the damper leg member is a meandering strip.
6. The speaker device according to claim 1 , wherein the damper leg member is positioned in a corner area of the frame.
7. The speaker device according to claim 1 , wherein the speaker damper is mirror symmetric.
8. The speaker device according to claim 1 , wherein the number of coil brackets of each speaker damper is at least two.
9. The speaker device according to claim 1 , wherein the two opposite directed diaphragms are at a mutual distance at rest which is equal to twice the operational excursion distance of the at least one motor drivers.
10. The speaker device according to claim 1 , wherein a speaker damper is present on two opposite sides of each of the two opposite directed diaphragms.
11. The speaker device according to claim 10 , wherein the combination of diaphragm and the speaker damper is a single working piece.
