  • a plug-receiving cavity 82 of the jack 42 is generally defined by an inner surface 84 of the sleeve 70 and is sized to receive a plug 48 of a headset (not shown).
  • the electrical connectors 72, 74, 76, 78 each include a conductive surface 80 that extends into the plug-receiving cavity 82.
  • the conductive elements 80 of the electrical connectors 72, 74, 76, 78 mate with corresponding conductive surfaces of electrical connectors 58, 60, 62 and 64 of the plug 48, respectively, to provide an electrical path between headset components, which include a microphone, a left speaker and a right speaker, and matching ports of the processor 14.

  • a pin-out of the plug 48 and a pin-out of the jack 42 should match.
  • the term pin-out is well known in the art and describes the purpose of each connector, which is commonly referred to as a pin, in a connecting device, such as a jack or a plug, for example.
  • the pin-out of the jack 42 of the portable electronic device 10 of Figure 1 is as follows: Electrical connector 72 Microphone Electrical connector 74 Ground Electrical connector 76 Right Audio channel Electrical connector 78 Left Audio Channel
  • the electrical connectors 72, 74, 76, 78 are electrically coupled to the processor 14 via a switching circuit 88, which is shown in Figure 4 .
  • the switching circuit 88 is provided to determine the pin-out of the plug 48 and swap microphone and ground signals when the pin-out of the plug 48 does not match the pin-out of the jack 42.
  • the switching circuit 88 determines if electrical connector 58 is electrically grounded and, if so, routes audio signals from electrical connector 60 of the plug 48, if ungrounded, through electrical connector 72 of the jack 42 to the processor 14.
  • the switching circuit 88 uses impedance testing to determine the pin-out of the plug 48.
  • Voltages are measured with respect to some sort of reference voltage, which is called the ground.
  • the voltage of the Earth itself serves as the reference, or ground.
  • one electrical node is selected to be the "ground node,” and it is with reference to the voltage of this node that other voltages are measured.
  • a connector is "electrically grounded” can be to mean that the connector is electrically coupled to, or is at substantially the same electric potential as, that ground node.
  • the voltage of a grounded connector has substantially zero difference in voltage with the ground node, and so would be measured as having a substantially constant voltage of about zero volts. Since typical electrical signals involve voltage changes, a connector that is electrically grounded typically is carrying no signal.
  • the switching circuit 88 includes a normally closed switch 98 between electrical connector 78 of the jack 42, which corresponds to the left audio channel, and an accessory detection circuitry 92.
  • the switching circuit 88 is in an idle mode when no plug 48 is received in the jack 42.
  • the normally closed switch 98 opens and a signal interrupt is sent to the processor 14 to notify the processor 14 that an audio accessory has been inserted into the jack 42.
  • the processor 14 performs a test to determine if the electrical connector 58 of the plug 48 is electrically grounded.
  • the test is an impedance test that the processor 14 performs by: 1) applying a voltage to a microphone bias connector 94 to bias the electrical connector 72; 2) reading a direct current (dc) voltage at a microphone detection connector 96; and 3) comparing the dc voltage reading to a predetermined threshold value, Vth.
  • a switch 90 of the switching circuit is in a first position, which is the default position, to route audio signals from electrical connectors 58 and 60 of the plug 48 to mating electrical connectors 72 and 74 of the jack 42.
  • a dc voltage reading that is high indicates that the electrical connector 58 is not electrically grounded. Therefore, it follows that the electrical connector 58 is connected to a microphone and the audio accessory is a headset, as indicated at state 104.
  • a four pole stereo headset plug is shown in Figure 6 and a four pole mono headset plug is shown in Figure 7 .
  • the switching circuit 88 determines that the electrical connector 58 is not electrically grounded and the processor 14 operates the audio accessory with the adapter switch 90 in the first position.
  • a dc voltage reading from the impedance test that is low indicates that the electrical connector 58 is electrically grounded, and therefore, the accessory is either a headset or headphones.
  • the switch 90 is changed to a second position in which the electrical connector 72 of the jack 42 is in communication with the electrical connector 60 of the plug 48.
  • the processor 14 then performs a second test in order to determine if the electrical connector 60 of the plug 48 is electrically grounded. If the dc voltage reading of the second test is high, the electrical connector 60 is not electrically grounded. Therefore, it follows that the electrical connector 60 is connected to a microphone and the audio accessory is a headset, as indicated at state 108.
  • This pin-out configuration is often found in headphones and headsets that are manufactured in China.
  • the switching circuit 88 allows the processor 14 to operate the audio accessory with the switch 90 in the second position.
  • a dc voltage reading from the second test that is low indicates that the electrical connector 60 is electrically grounded, and therefore, the accessory is a set of headphones, as indicated at state 110. Plugs for stereo headphones and mono headphones are shown in Figures 9 and 10 , respectively.
  • a further detection scheme may be performed in order to determine the entire pin-out of the plug 48, as indicated in Figure 5 .
  • Detection schemes for determining whether a headset or headphones is mono or stereo are known in the art and therefore will not be described further.
  • a method for connecting the plug 48 of an audio accessory to a portable electronic device is generally shown.
  • the plug 48 is received in the jack 42 of the portable electronic device.
  • the pin-out of the plug 48 is then determined at step 114, as has been previously described, and audio signals from electrically ungrounded electrical connectors of the plug 48 are routed to matching ports of the processor 14 at step 116.
  • a method according to the invention for connecting a plug of an audio accessory to a portable electronic device is generally shown.
  • the plug 48 is received in the jack 42 of the portable electronic device.
  • the jack 42 shown in Figure 3 is sized to receive a 3.5 mm plug, however, it will be appreciated by a person skilled in the art that the jack 42 may alternatively be sized to receive a 2.5 mm plug or another size of plug.
  • the jack 42 includes a pin-out of: Electrical connector 72 Ground Electrical connector 74 Microphone Electrical connector 76 Right Audio channel Electrical connector 78 Left Audio Channel
  • the switching circuit 88 is modified to first test if electrical connector 60 of the plug 48 is electrically grounded and, if not, change switch 90 to the second position and re-test.
  • the switching circuit 88 of the described embodiments is suitable for use with plugs having microphone and ground electrical connectors that are located adjacent to one another at the base of the plug and in which at least one of the two connectors located adjacent to the tip of the plug are speaker electrical connectors.
  • Plug pin-outs having this general configuration are shown in Figures 6-10 and are the most common pin-out configurations of headset and headphone accessories. It will, however, be appreciated by a person skilled in the art that a modified switching circuit including additional switches and further impedance testing could be provided to allow for pin-out determination of any pin-out configuration.
  • the modified switching circuit would route audio signals between ungrounded ones of the electrical connectors of the plug and matching ports of the processor.
  • the processor 14 executes software that is stored on the device 10 to allow a user to select different pin-out options via the keypad 38, display 20 or other input devices 36.
  • the processor 14 would not perform a test to determine the pin-out of the audio accessory. Instead, when the switching circuit 88 detects that an audio accessory has been inserted into the jack 42, the user would be prompted to select the type of audio accessory. The user would be able to select the type of audio accessory from a drop-down list, for example, which could include a list of pin-outs, product manufacturers, product serial numbers or a list of countries corresponding to where the accessory was manufactured.
