Abstract

An apparatus including an audio transducer configured to generate sound and a structure configured to physically mount the transducer to another member. The transducer includes a housing, a diaphragm and a driver configured to move the diaphragm. The structure at least partially includes the housing. The structure includes at least one portion which is electrically conductive. The at least one portion is electrically connected to the driver.

First claim

What is claimed is:

1. An apparatus comprising an audio transducer configured to generate sound and a structure configured to electrically interface the audio transducer with circuitry of an electronic device when the audio transducer is received by the electronic device, where the audio transducer comprises a housing, a diaphragm and a driver configured to move the diaphragm, where the housing at least partially comprises the structure, where at least one portion of the structure is electrically conductive and connected to the driver, and where the structure is further configured to provide an acoustic sealing functionality with the electronic device when the audio transducer is connected to the electronic device.

2. An apparatus as in claim 1 where the apparatus comprises no separate spring electrical contact terminal or leaf electrical contact terminal for the driver mounted to the housing of the transducer.

3. An apparatus as in claim 1 where the at least one portion of the structure comprises at least one electrically conductive section of the housing which is stationary on the housing of the transducer.

4. An apparatus as in claim 3 where the at least one electrically conductive section of the housing comprises an electrically conductive trace on the housing.

5. An apparatus as in claim 3 where the at least one electrically conductive section of the housing comprises at least one contact area at a front side of the housing.

6. An apparatus as in claim 3 where the at least one electrically conductive section of the housing comprises at least one contact area at a rear side of the housing.

7. An apparatus as in claim 3 where the structure comprises a gasket, where the gasket comprises an electrically conductive section which is located against the at least one electrically conductive section of the housing of the transducer.

8. An apparatus as in claim 7 where the gasket is mounted to a front cover of the housing.

9. A device comprising:
the apparatus as claimed in claim 1 ;
at least one printed wiring board, where the apparatus is mounted to a first one of the at least one printed wiring board, where the first printed wiring board forms the electronic device;
an electrical display connected to the at least one printed wiring board;
a receiver connected to the at least one printed wiring board;
a transmitter connected to the at least one printed wiring board;
a processor connected to the at least one printed wiring board;
a memory connected to the at least one printed wiring board; and
a battery connected to the at least one printed wiring board.

10. An apparatus as in claim 1 where the at least one electrically conductive portion of the structure is configured to form at least a portion of an acoustic seal.

11. An apparatus as in claim 1 where the at least one electrically conductive portion of the structure is at a flexible portion of the housing.

12. An apparatus as in claim 1 where the diaphragm is located proximate a front side of the audio transducer and where the at least one electrically conductive portion of the structure is located at the front side of the audio transducer.

13. An apparatus as in claim 1 where the at least one electrically conductive portion of the structure is on a compressible portion of the housing.

14. An apparatus as in claim 1 where the structure is configured to attach a gasket thereto, such that a combination of the at least one electrically conductive portion of the structure and the gasket are configured to at least partially provide at least one of:
the acoustic sealing functionality for the audio transducer;
a mechanical cushion functionality for the audio transducer; and
an electrical conductivity for the audio transducer.

15. An apparatus as in claim 14 where the gasket comprises adhesive tape attached to the housing.

16. An apparatus as in claim 14 where the gasket is attached to the housing and comprises at least one dielectric portion and at least two electrically conductive sections.

17. An apparatus as in claim 1 where the structure is configured to physically mount the audio transducer to the electronic device, where the at least one electrically conductive portion of the structure is an integrally formed part of the housing being at least one of: molded in, printed, glued, laser glued, and overmolded.

18. A method comprising:
providing an audio transducer configured to generate sound, where the audio transducer comprises a housing, a diaphragm and a driver for moving the diaphragm;
providing an arrangement which is configured to physically mount the audio transducer to an electronic device, where at least one portion of the arrangement at least partially comprises the housing, where the at least one portion of the arrangement is electrically conductive, and where the at least one electrically conductive portion of the arrangement and at least one other portion of the arrangement are configured to provide an acoustic sealing functionality when the audio transducer is connected to the electronic device; and
connecting the driver electrically to the at least one portion.

19. A method as in claim 18 where no separate electrical spring contact terminals are mounted to the housing of the transducer.

20. A method as in claim 18 where the at least one portion of the arrangement includes providing at least one electrically conductive section of the housing which is stationary on the housing of the transducer.

21. A method as in claim 20 where the at least one electrically conductive section of the housing includes providing at least one electrically conductive trace on the housing.

22. A method as in claim 20 where the at least one electrically conductive section of the housing includes providing at least one contact area at a front side of the housing.

23. A method as in claim 20 where the at least one electrically conductive section of the housing includes providing at least one contact area at a rear side of the housing.

24. A method as in claim 18 where the arrangement comprises providing a gasket, where the gasket comprises an electrically conductive section which is located against the at least one electrically conductive portion of the arrangement and electrically connecting the gasket to the housing.

25. A method as in claim 24 where the gasket is mounted to a front cover of the housing.

26. An apparatus comprising:
