Abstract

A loudspeaker arrangement for a passenger cabin of a transport means, including a loudspeaker and a housing having a receiver for the loudspeaker. The loudspeaker includes at least one membrane capable of oscillation and at least one loudspeaker coil. The loudspeaker coil is integrated into the membrane capable of oscillation, wherein the membrane electrically insulates the loudspeaker coil at least in part.

First claim

The invention claimed is:

1. A loudspeaker arrangement for a passenger cabin of a transport structure or vehicle, comprising
a loudspeaker and a housing having a receiver for the loudspeaker;
the loudspeaker comprising a first membrane capable of oscillation, a first loudspeaker coil, and a magnet arrangement;
the first loudspeaker coil being integrated into the first membrane capable of oscillation; and
wherein the first membrane capable of oscillation electrically insulates the first loudspeaker coil at least in part,
wherein the magnet arrangement is arranged to produce a magnetic field to exert a magnetic force on at least portions of the first membrane capable of oscillation through which an electrical conductor passes, and
wherein at least one magnet of the magnet arrangement, which is a magnetic foil, is capable of oscillation and arranged to emit sound in conjunction with the first membrane capable of oscillation.

2. The loudspeaker arrangement of claim 1 , wherein the first loudspeaker coil is formed by an electrical conductor which extends in a shape of a spiral substantially orthogonally to a thickness direction of the first membrane capable of oscillation and which passes through the first membrane capable of oscillation at least at connection points.

3. The loudspeaker arrangement of claim 1 , further comprising:
a second membrane capable of oscillation and a second loudspeaker coil;
the second loudspeaker coil being integrated into the second membrane capable of oscillation; and
wherein the second membrane capable of oscillation electrically insulates the second loudspeaker coil at least in part.

4. The loudspeaker arrangement of claim 3 , wherein the second loudspeaker coil is formed by an electrical conductor which extends in a shape of a spiral substantially orthogonally to a thickness direction of the second membrane capable of oscillation, and passes through the second membrane capable of oscillation at least at connection points.

5. The loudspeaker arrangement of claim 3 , wherein the first loudspeaker coil is electrically connected to the second loudspeaker coil at at least one connection point.

6. The loudspeaker arrangement of claim 1 , further comprising:
an arrangement of electronic components which is integrated into the first and/or into the second membrane, wherein the arrangement of electronic components comprises resistors, diodes, transistors, thyristors, photosemiconductors, and/or components having capacitive or inductive properties.

7. The loudspeaker arrangement of claim 1 , wherein
the first membrane capable of oscillation is formed by a portion of the housing, or
the first membrane capable of oscillation is connected to the housing by adhesive bonding or lamination, and/or
the first membrane capable of oscillation is flush with the housing surrounding it in the rest state and forms a planar surface without raised elements.

8. The loudspeaker arrangement of claim 1 , wherein the first membrane capable of oscillation is configured and arranged to form an outer side of the loudspeaker with one of its surfaces.

9. The loudspeaker arrangement of claim 1 , wherein
the first and/or the second membrane capable of oscillation is manufactured at least in part of carbon-fiber-reinforced plastics material, glass-fiber-reinforced plastics material, polyphenylene terephthalamide or polytetrafluoroethylene, and/or
the first and/or the second membrane capable of oscillation each has one or more air equalization hole, and/or
the housing has one or more air equalization hole.

10. The loudspeaker arrangement of claim 3 ,
wherein the magnet arrangement is configured and arranged to produce a magnetic field which exerts a magnetic force on at least portions of the first and the second membranes capable of oscillation through which an electrical conductor passes, and
wherein a surface of each of the first and/or the second membrane capable of oscillation faces the magnet arrangement.

11. The loudspeaker arrangement of claim 1 , wherein
at least one magnet of the magnet arrangement is an electromagnet, and/or
at least one magnet of the magnet arrangement is a permanent magnet.

12. The loudspeaker arrangement of claim 1 , wherein the magnetic foil is capable of oscillation in a frequency range from 16 Hz to 20 kHz and
is configured and arranged to emit sound in conjunction with the first and/or the second membrane capable of oscillation.

13. The loudspeaker arrangement of claim 3 , wherein
the housing is manufactured by a 3D printing process, and/or
the receiver is manufactured by a 3D printing process, and/or
the first and/or the second membrane capable of oscillation is manufactured by a 3D printing process, and/or
the first and/or the second loudspeaker coil is manufactured by a 3D printing process, and/or
the magnet arrangement is manufactured, at least in part, by a 3D printing process, and/or
an arrangement of electronic components is manufactured by a 3D printing process.

14. A passenger cabin for a transport structure or vehicle, comprising a loudspeaker arrangement comprising:
a loudspeaker and a housing having a receiver for the loudspeaker;
the loudspeaker comprising a first membrane capable of oscillation, a first loudspeaker coil, and a magnet arrangement;
the first loudspeaker coil being integrated into the first membrane capable of oscillation; and
wherein the first membrane capable of oscillation electrically insulates the first loudspeaker coil at least in part,
wherein the housing of the loudspeaker is formed by part of the passenger cabin or is permanently connected to the passenger cabin,
wherein the magnet arrangement is arranged to produce a magnetic field to exert a magnetic force on at least portions of the first membrane capable of oscillation through which an electrical conductor passes, and
wherein at least one magnet of the magnet arrangement, which is a magnetic foil, is capable of oscillation and is arranged to emit sound in conjunction with the first membrane capable of oscillation.

15. The passenger cabin of claim 14 , wherein the transport structure or vehicle comprises an aircraft.
