Abstract

Embodiments herein enable fast and easy interconnectivity among multimedia accessories including mobile devices and other devices. There is only limited space on mobile devices yet there are numerous input connectors. The standard TRRS audio jack is one such input that has and remains common, primarily because it is the accepted standard for audio input; namely, headphones and earpieces for listening purposes. Embodiments herein describe an intelligent switch to that audio jack that permits for additional backward and forward compatibility. It transparently allows a user to insert analog or digital audio devices, such as earphones, without the need to manually reconfigure device settings. The device herein automatically converts between input connector types using the same input convention present on their existing mobile devices. Other embodiments are disclosed.

Claims

1. A device, comprising:

a processing unit communicatively coupled to one or more multimedia connections comprising tip, ring, ring, sleeve (TRRS) audio, universal serial bus, a proprietary serial protocol, or a combination thereof, wherein the processing unit perform operations comprising;

detecting an audio configuration of an audio device by way of current and load sensing through an audio jack of the device; and

independently assigning, upon detection of a connector type of an audio connector of the audio device, data lines to or from the audio device to pins utilized for a TRRS line connection in accordance with the connector type, wherein the audio jack is communicatively coupled to the processing unit using the TRRS line connection.

2. The device of claim 1, wherein the operations further comprise reconfiguring the pins upon detecting a microphone signal.

3. The device of claim 1, wherein the operations further comprise recognizing and arbitrating a dynamic pin allocation on the audio jack to accommodate a multimedia type of the audio device.

4. The device of claim 3, wherein the operations further comprise recognizing and arbitrating the dynamic pin allocation on the audio jack upon insertion of the audio device by way of the audio connector inserted into the audio jack.

5. The device of claim 1, wherein the operations further comprise providing analog switching in conjunction with digital format conversion.

6. The device of claim 1, wherein the operations further comprise measuring a current resistance or other loading of signals placed on the TRRS line connection.

7. The device of claim 1, wherein the operations further comprise injecting a line signal, voltage, or current into the audio jack to assess a response of the audio device.

8. The device of claim 1, wherein the operations further comprise negotiating a communication connection with a multimedia service.

9. The device of claim 1, wherein the operations further comprise converting between multimedia types and formats.

10. The device of claim 1, wherein the operations further comprise relaying and buffering digital packets if the audio device is a digital earphone.

11. The device of claim 1, wherein the operations further comprise overriding default TRRS pin settings for the pins after detecting the connector type of the audio connector.

12. The device of claim 1, wherein the operations further comprise detecting a presence of an analog microphone signal and, by way of switching logic, reconfiguring the pins based on the analog microphone signal.

13. The device of claim 1, wherein the operations further comprise interleaving or overlaying a detected microphone signal with a speaker signal.

14. A method, comprising:

detecting, by utilizing a processing unit of a device coupled to one or more multimedia connections comprising tip, ring, ring, sleeve (TRRS) audio, universal serial bus, a proprietary serial protocol, or a combination thereof, an audio configuration of an audio device by way of current and load sensing through an audio jack of the device; and

independently assigning, by utilizing the processing unit and upon detection of a connector type of an audio connector of the audio device, data lines to or from the audio device to pins utilized for a TRRS line connection in accordance with the connector type, wherein the audio jack is communicatively coupled to the processing unit using the TRRS line connection.

15. The method of claim 14, further comprising providing backwards compatibility and interoperability with multimedia functions available to a host platform communicatively coupled to, or implemented by, the device.

16. The method of claim 14, further comprising authenticating the audio device by way of signal detection through an identifier component of the audio connector.

17. The method of claim 14, further comprising injecting a line signal, voltage, or current into the audio jack to assess a response of the audio device.

18. The method of claim 14, further comprising overriding default TRRS pin settings for the pins after detecting the connector type of the audio connector.

19. The method of claim 14, further comprising conveying a communication request to automatically download device drivers or plug-ins to support the audio device.

20. A controller, comprising:

a processing unit communicatively coupled to one or more multimedia connections comprising tip, ring, ring, sleeve (TRRS) audio, universal serial bus, a proprietary serial protocol, or a combination thereof, wherein the processing unit perform operations comprising;

determining an audio configuration of an audio device by way of current and load sensing through an audio jack of the device; and

assigning, upon detection of a connector type of an audio connector of the audio device, data lines to or from the audio device to pins utilized for a TRRS line connection in accordance with the connector type, wherein the audio jack is communicatively coupled to the processing unit using the TRRS line connection.
