BACKGROUND
An audio device, such as an earphone or earphones, an ear microphone, a headphone, a headset, etc., may be used while being connected to an electronic device. The audio device may include a speaker and may further include a microphone. The audio device including the speaker and the microphone may receive an audio signal from the electronic device to output audio through the speaker and may output an audio signal, input via the microphone, to the electronic device.
The audio device may further include additional function units, such as a radio reception block, an active noise cancelling block (hereinafter, referred to as an ‘ANC block’), etc. The radio reception block may be used by a user to listen to a radio broadcast. The ANC block may be used to reduce noise around the audio device. The ANC block may reduce ambient noise by receiving an ambient sound, inverting the phase of the audio signal of the ambient sound, and then superimposing the inverted audio signal on an audio signal to be output through the speaker.
The microphone of the audio device may be driven by power supplied from the electronic device. The electronic device may supply electric power with a current of, for example, several mA, or 1 mA or less to the audio device in order to drive the microphone of the audio device. The additional function units, such as the radio reception block and the ANC block, require a higher consumption current than the microphone. For example, a current of about tens of mA is required to drive the ANC block.
An additional power line may be connected between the electronic device and the audio device in order to supply power for driving the ANC block from the electronic device to the audio device. The audio device may have an embedded battery for driving the ANC block, instead of receiving the power for driving the ANC block from the electronic device.
The audio device includes an audio device connector to connect to the electronic device. In addition, the electronic device also includes an electronic device connector to connect to the audio device.
The audio device connector has a jack shape based on the 3.5 mm standard, and the electronic device connector may be embodied as a socket shape. When the connector of the audio device having a jack shape is inserted into the connector of the electronic device having a socket shape, an L channel audio terminal, an R channel audio terminal, a ground terminal, and a microphone terminal, which are included in the audio device connector, are electrically connected to an L channel audio terminal, an R channel audio terminal, a ground terminal, and a microphone terminal, which are included in the electronic device connector, respectively.

Referring to FIG. 1, the electronic device 102 may include a bus 110, a processor 120, a memory 130, an input/output interface 140, a display 150, and a communication interface 160. The bus 110 may be a circuit for connecting elements of the electronic device 102 and transferring communication (e.g., a control message) between the elements.
The processor 120 may, for example, receive instructions from the other elements (e.g., the memory 130, the input/output interface 140, the display 150, the communication interface 160, etc.) through the bus 110, decode the received instructions, and execute operations or data processing based on the decoded instructions.
The memory 130 may store instructions or data received from, or generated by the processor 120 or the other elements (e.g., the input/output interface 140, the display 150, and the communication interface 160, etc.). The memory 130 may include, for example, programming modules, such as a kernel 131, middleware 132, an application programming interface (API) 133, applications 134, etc. The programming modules may be configured with software, firmware, hardware, or a combination of two or more thereof.
The kernel 131 may control or manage system resources (e.g., the bus 110, the processor 120, the memory 130, etc.) that are used to execute operations or functions implemented in the other programming modules, for example, the middleware 132, the API 133, and the applications 134. Further, the kernel 131 may provide an interface through which the middleware 132, the API 133, or the applications 134 access individual elements of the electronic device 102 to control or manage the elements.
The middleware 132 may function as an intermediary that makes the API 133 or the applications 134 communicate with the kernel 131 to exchange data. Further, in regard to task requests received from the applications 134, the middleware 132 may, for example, execute a control (e.g., scheduling or load balancing) for the task requests using a method of assigning a priority to use system resources of the electronic device 102 (e.g., the bus 110, the processor 120, the memory 130, etc.) to at least one of the applications 134.
The API 133 is an interface used, by the application 134, to control a function provided from the kernel 131 or the middleware 132, and may include, for example, at least one interface or function (e.g., instruction) for file control, window control, image processing, text control, etc.

The switch 220 and the resistors 222, 224 may be connected between the output end of the power source device 218 and the microphone terminal 216. The switch 220 may be controlled by the controller 208 to apply the output power of the power source device 218 to the microphone terminal 216 via one of the resistors 222, 224. Power is applied from the power source device 218 via the switch 220 and the resistor 222 to the microphone terminal 216 and is applied from the power source device 218 via the switch 220 and the resistor 224 to the microphone terminal 216.
The resistor 222 may have a higher resistance value than the resistor 224. The resistor 222 may have a resistance value corresponding to the consumption current of the microphone 260. The resistor 224 may have a resistance value corresponding to the consumption current of the ANC block 254. For example, the resistor 222 may have a resistance value of 2.21 kΩ, and the resistor 224 may have a resistance value of 100Ω.
The ANC terminal 15 of the audio side connector 252 may be connected to the ANC block 254. The ANC block 254 may be driven by the power input from the ANC power source unit 11 of the electronic device 200 via the ANC terminal 15. The ANC block 254 may perform an ANC process on an L channel audio signal and an R channel audio signal, which are input from the electronic device 200 via the L channel audio terminal 264 and the R channel audio terminal 266, and may output the processed L channel audio signal and R channel audio signal via the L channel speaker 256 and the R channel speaker 258, respectively.
The microphone 260, the pair of the volume up switch 272 and the resistor 278 connected in series to each other, the pair of the volume down switch 274 and the resistor 280 connected in series to each other, and the pair of the send/end switch 276 and the resistor 282 connected in series to each other may be connected in parallel to each other between the microphone terminal 270 and the ground terminal 268. The volume up switch 272, the volume down switch 274, and the send/end switch 276 may be an automatic reset contact type push button switch that is turned on when pressed and turned off when released. The volume up switch 272 may be used as a volume up key for indicating an increase in volume to the electronic device 200. The volume down switch 274 may be used as a volume down key for indicating a decrease in volume to the electronic device 200. The send/end switch 276 may be used as a send/end key for indicating a beginning and an end of a call.
The resistors 278, 280, 282 may have different resistance values. Therefore, in cases where the volume up switch 272, the volume down switch 274, and the send/end switch 276 are turned on, the voltage of the microphone terminal 216 may vary. For example, the resistor 278 may have a resistance value of 619Ω, the resistor 280 may have a resistance value of 221Ω, and the resistor 282 may have a resistance value of 50Ω. Accordingly, based on the voltage of the microphone terminal 216, the electronic device 200 may identify the type of switch which is turned on among the volume up switch 272, the volume down switch 274, and the send/end switch 276.
The type-setting unit 262 may be connected to the microphone terminal 270. The type-setting unit 262 may provide a voltage indicating that the earphones 250 are of a type including the ANC block 254 to the electronic device 200 via the microphone terminal 270. The type-setting unit 262 may include a resistor 284 connected between the microphone terminal 270 and the ground. The resistor 284 may have a different resistance value than the resistors 278, 280, 282.
If earphones not including the resistor 284 are connected to the electronic device 200, a voltage caused by the resistor 284 will not appear on the microphone terminal 216. Therefore, the electronic device 200 may identify whether the earphones 250 are of a type including the ANC block 254 on the basis of the voltage of the microphone terminal 216.
Among elements of an audio device and an electronic device, according to an embodiment of the present disclosure, connectors will be hereinafter described as follows.

FIG. 4 is a side view illustrating a state where a connector of an audio device, such as the connector of the audio device illustrated in FIG. 3, is inserted into a connector of an electronic device according to an embodiment of the present disclosure.
Referring to FIGS. 2 and 3, the audio device 250 includes the audio side connector 252, the ANC block 254, the ANC power source unit 11, and the on/off switch unit 12.
The audio side connector 252 may include the microphone terminal 270 for outputting a microphone signal to the electronic device 200, the L channel audio terminal 264 and the R channel audio terminal 266 for receiving an audio signal from the electronic device 200, and the ANC terminal 15 and the ground terminal 268 for applying power input from the electronic device 200 to the ANC block 254.
Referring to FIG. 2 mentioned above, the connectors 202, 252 of the electronic device 200 and the audio device 250 may be configured with a 5-pole connector that includes the L channel audio terminals 210, 264, the R channel audio terminals 212, 266, the ANC terminals 14, 15, the ground terminals 214, 268, and the microphone terminals 216, 270.
The ANC block 254 may be provided in the audio device 250 such that the ANC block 254 is driven by power input from the electronic device 200 to remove noise around the audio device 250.
The ANC power source unit 11 may be provided in the electronic device 200 to apply the power to the ANC block 254 via the ANC terminals 14, 15 as drive power.
The on/off switch unit 12 may be provided in the electronic device 200 to turn on/off the power of the ANC power source unit 11.
The ANC terminal 15 may be included in one of the area of the microphone terminal 270, the area of the L channel audio terminal 264, the area of the R channel audio terminal 266, and the area of the ground terminal 268.
In this embodiment, the ANC terminal 15 is included in the area of the R channel audio terminal 266.
Namely, in cases where the ANC terminal 15 is included in the area of the R channel audio terminal 266, a non-contact area 16 may be provided between the ANC terminal 15 and the R channel audio terminal 266 to partition the ANC terminal 15 and the R channel audio terminal 266.
Referring to FIG. 3, the audio side connector 252 may be configured with a 5-pole terminal while maintaining an existing jack shape based on the 3.5 mm standard as it is. In other words, the ANC terminal 15 of the audio side connector 252 may be included in the area of the existing R channel audio terminal 266 without a change in the size of the audio side connector 252.
Likewise, the electronic device side connector 202 may be configured in a socket shape of a 5-pole terminal to correspond to the audio side connector 252 configured with the 5-pole terminal. The ANC terminal 14 of the electronic device side connector may be electrically connected to the ANC terminal 15 of the audio side connector 252 without a change in the size of the electronic device side connector 202 due to the use of the existing ground terminal included in the electronic device side connector 202. In addition, specific dimensions of the size of the audio side connector 252 are disclosed as illustrated in FIG. 3.
Since the ANC terminal 15 is configured by including the non-contact area 16 in the area of the existing R channel audio terminal 266, it is possible to supply the power of the electronic device to the ANC block 254 of the audio device via the ANC terminal 15 while maintaining the shape of the existing connector of the audio device. Therefore, since an existing battery (not illustrated) included in the audio device is not required, compactness and slimness of the audio device 250 can be achieved, and since additional maintenance of the battery is also not necessary, costs for the audio device can be reduced.
Further, the electronic device 200 may include the popup prevention circuit device unit 13 which removes popup noise generated when the ANC power source unit 11 supplies electric power to the audio device 250 or cuts off the power supply via the on/off switch unit 12.
Namely, when electric power is applied to the ANC block 254 by the on/off switch unit 12, or the power is cut off by the on/off switch unit 12, a surge pulse may occur due to an unstable bias voltage of an internal circuit. The surge pulse may be amplified by a driving circuit and may generate uncomfortable noise through a speaker, etc. The noise is referred to as the popup noise.
The popup prevention circuit device unit 13 may remove such popup noise.
In this state, operations of the connectors of the audio device and the electronic device will be described in more detail with reference to FIG. 4 as follows.

Here, a current of about tens of mA is required to drive the ANC block 254. For example, the current of the ANC block 254 may be 12 mA, but is not limited thereto. That is, the current of the ANC block may also be 12 mA or more, or 12 mA or less.
In addition, the ANC terminal 15 may supply electric power to an accessory (not illustrated) included in the audio device 250 as well as the ANC block 254. That is, the ANC terminal 15 is illustrated as a terminal for supplying electric power to the ANC block 254, but is not limited thereto. If the ANC terminal 15 is connected to a terminal of the accessory to supply the power of the ANC power source unit 11 of the electronic device 200 to the accessory, the ANC terminal 15 may be applied to various accessories.
