HYBRID ANALOG/DIGITAL HEADSET
A device comprising a detector configured to receive an indication from a terminal of a connector and to determine whether the indication matches an expected result. One or more first switches are configured to connect one or more speaker transducers to the connector if the indication is false. One or more second switches are configured to connect the one or more speaker transducers to a digital output converter if the indication is true. The device can also include one or more third switches configured to connect one or more microphone elements to the connector if the indication is false, and one or more fourth switches configured to connect one or more microphones to a digital input converter if the indication is true. The input and output converters can be stand alone or part of a digital signal processor.
1 . A device comprising:
a detector configured to receive an indication from a terminal of a connector and to generate a control signal if the indication is present;
one or more first switches configured to connect one or more speaker transducers to the connector if the indication is not present; and
one or more second switches configured to connect the one or more speaker transducers to a processor if the indication is present.
2 . The device of claim 1 further comprising one or more third switches configured to connect the processor to the connector if the indication is present.
3 . The device of claim 1 wherein the detector is configured to generate the control signal to cause the one or more first switches for connecting the one or more speaker transducers to the connector to change state.
4 . The device of claim 1 wherein the detector is configured to generate the control signal to cause the one or more second switches for connecting the one or more speaker transducers to the processor to change state.
5 . The device of claim 2 wherein the detector is configured to generate the control signal to cause the one or more third switches for connecting the processor to the connector to change state.
6 . The device of claim 1 wherein the one or more first switches are normally closed.
7 . The device of claim 1 wherein the one or more second switches are normally open.
8 . The device of claim 2 wherein the one or more third switches are normally open.
9 . The device of claim 1 further comprising:
one or more third switches configured to connect one or more microphones to the connector if the indication is not present; and
one or more fourth switches configured to connect the one or more microphones to the processor if the indication is present.
10 . The device of claim 9 wherein the one or more third switches are normally closed.
11 . The device of claim 9 wherein the one or more fourth switches are normally open.
12 . The device of claim 9 further comprising one or more fifth switches configured to connect the processor to the connector if the indication is present.
13 . A method for controlling a device comprising:
receiving an indication from a connector;
connecting one or more speaker transducers to the connector if the indication is false; and
connecting the one or more speaker transducers to a processor if the indication is true.
14 . The method of claim 13 wherein connecting the one or more speaker transducers to the connector if the indication is false comprises allowing one or more normally closed switches to remain closed.
15 . The method of claim 13 wherein connecting the one or more speaker transducers to the processor if the indication is true comprises causing one or more normally open switches to close.
16 . The method of claim 13 further comprising connecting one or more microphones to the connector if the indication is false.
17 . The method of claim 13 further comprising connecting the one or more microphones to the processor if the indication is true.
18 . The method of claim 13 wherein connecting the one or more speaker transducers to the processor if the indication is true comprises generating a control signal to cause one or more normally open switches to close.
19 . The method of claim 16 wherein connecting one or more of the microphones to the connector if the indication is false comprises generating a switch control signal to change a state of one or more switches.
20 . A device comprising:
a detector configured to receive an indication from a terminal of a connector and to generate a control signal if the indication is present;
one or more first switches configured to connect one or more speaker transducers to the connector if the indication is not present;
one or more second switches configured to connect the one or more speaker transducers to a processor if the indication is present;
one or more third switches configured to connect the processor to the connector if the indication is present;
one or more fourth switches configured to connect one or more microphones to the connector if the indication is not present;
one or more fifth switches configured to connect the one or more microphones to the processor if the indication is present;
one or more sixth switches configured to connect the processor to the connector if the indication is present; and
wherein the detector is configured to generate the control signal to cause the one or more first switches for connecting the one or more speaker transducers to the connector to change state, the detector is configured to generate the control signal to cause the one or more second switches for connecting the one or more speaker transducers to the processor to change state, the detector is configured to generate the control signal to cause the one or more third switches for connecting the processor to the connector to change state, the one or more first switches are normally closed, the one or more second switches are normally open, the one or more third switches are normally open, the one or more fourth switches are normally closed, the one or more fifth switches are normally open and the one or more sixth switches are normally open.
