Abstract

A sound recording and/or sound reproducing part loosely anchored/connected to a second part wherein the sound recording and/or sound reproducing part is levitated on a magnetic field. The sound recording and/or sound reproducing part and the second part in combination forms a first sound recording and/or sound reproducing device. The sound recording and/or sound reproducing part can be used within on or more of the following devices; a loud speaking telephone, a telephone, wireless communication equipment, a mobile phone, a Bluetooth device, a videoconference terminal, a hearing aid or active ear protection equipment.

Claims (24)

1. A sound recording or sound reproducing part loosely anchored/connected to a second part, wherein the sound recording or sound reproducing part is levitated by a magnetic field.

2. A sound recording or sound reproducing part according to claim 1 , wherein the sound recording or sound reproducing part and the second part in combination forms a first sound recording or sound reproducing device.

3. A sound recording or sound reproducing part according to claim 2 , wherein the first sound recording or sound reproducing device is an integral part of one or more of the following devices:

a loud speaking telephone, a telephone, wireless communication equipment, a mobile phone, a Bluetooth device, a videoconference terminal, a hearing aid and active ear protecting equipment.

4. A sound recording or sound reproducing part according to claim 2 , wherein the first sound recording or sound reproducing device forms a first layer, in a number of layers wherein each layer is levitated on a magnetic field between an upper and a lower layer.

5. A sound recording or sound reproducing part according to claim 4 , wherein the first sound recording or sound reproducing device is fixed sideways through gimbals, flexible pads, or flexible arms/fingers.

6. A sound recording or sound reproducing part according to claim 5 , wherein the sideways fixing arrangement comprises one or more arms/fingers stretching out from the first sound recording or sound reproducing device and the fixing arrangement is/are fixed to the lower layer.

7. A sound recording or sound reproducing part according to claim 6 , wherein the arms/fingers allow the first sound recording or sound reproducing device to move freely along an axis parallel to the magnetic flux lines between each layer.

8. A sound recording or sound reproducing part according to claim 4 , wherein a damping material/substrate is attached to one or both of the surfaces between the first sound recording or sound reproducing device and the lower layer.

9. A sound recording or sound reproducing part according to claim 2 , wherein the first recording or sound reproducing device is a tabletop microphone.

10. The use of a sound recording or sound reproducing part according to claim 2 , wherein said first sound recording or sound reproducing device can be used as an integral part in one or more of the following devices:

a loud speaking telephone, a telephone, a wireless communication equipment, a mobile phone, a Bluetooth device, a videoconference terminal, a hearing aid and active ear protecting equipment.

11. A sound recording or sound reproducing part according to claim 1 , wherein the magnetic field is achieved due to a permanent magnet or an electromagnet held by the sound recording or sound reproducing part and a magnet held by the second part, where the magnets have the same poles facing each other creating a repellent force which causes the sound recording or sound reproducing part to levitate.

12. A sound recording or sound reproducing part according to claim 1 , wherein the recording or sound reproducing part is fixed sideways through gimbals, flexible pads, or flexible arms/fingers.

13. A sound recording or sound reproducing part according to claim 12 , wherein the sideway fixing arrangement comprises one or more arms/fingers stretching out from the sound recording or sound reproducing part and the fixing arrangement is/are fixed to the second part.

14. A sound recording or sound reproducing part according to claim 13 , wherein the arms/fingers allow the sound recording or sound reproducing part to move freely along an axis parallel to the magnetic flux lines.

15. A sound recording or sound reproducing part according to claim 1 , wherein the sound recording or sound reproducing part is mechanically secured against mechanically interference.

16. A sound recording or sound reproducing part according to claim 15 , wherein the mechanical securing arrangement includes a safety bolt or a safety hook retention bolt.

17. A sound recording or sound reproducing part according to claim 1 , wherein a damping material/substrate is attached to one or both of the surfaces between the sound recording or sound reproducing part and the second part.

18. A sound recording or sound reproducing part according to claim 1 , wherein the sound recording or sound reproducing part holds a microphone.

19. A sound recording or sound reproducing part according to claim 1 , wherein the sound recording or sound reproducing part holds a speaker element.

20. A sound recording or sound reproducing part according to claim 1 , wherein signal or power transmission between the sound recording or the sound reproducing part and the second part comprises wireless transmission.

21. A sound recording or sound reproducing part according to claim 20 , wherein the wireless transmission comprises one or more of the following:

a Bluetooth connection/transmission, a radio connection different from the Bluetooth connection, ultraviolet connection/transmission, a magnetic connection/transmission, an optical connection/transmission and an inductively coupled system.
