BROADCAST RECEIVING METHOD AND APPARATUS OF ELECTRONIC DEVICE

TECHNICAL FIELD

The disclosure relates to an apparatus and a method for receiving a broadcast signal using a Type-C connector.

BACKGROUND ART

In recent years, a variety of electronic devices are being provided for users, and users can access different types of content while carrying various electronic devices. An electronic device may be connected to various external devices through an interface for connection with an external device (e.g., a USB connector), and may be connected to an external device to provide extended functions. An electronic device may include different types of connectors according to various interfaces.

Some connectors, for example, a 3.5 phi analog audio connector, among different types of connectors can support connection between an electronic device and an antenna (e.g., a DMB antenna or FM antenna) capable of receiving wireless communication data. Some other connectors, for example, a universal serial bus (USB) Type-C connector, do not support connection between an electronic device and an antenna.

In the case of a connector that does not support connection between an electronic device and an antenna, it is possible to support a specified function for an electronic device through the connector, but it may be impossible to support a wireless communication data reception function using an antenna.

DISCLOSURE OF INVENTION
Technical Problem

The USB Type-C standard specifies methods for transmitting a sound source through a digital line and reproducing a sound source by switching a digital line to an analog line. However, the standard does not specify configuration of an earphone antenna. Electronic devices are legally required to have an FM reception function for receiving a disaster broadcast. Therefore, a device and a method for receiving an FM signal using an earphone antenna device with a USB Type-C connector are required.

When a method of commonly using a ground (GND) is used, in a Type-C connector, like a 3.5 phi connector, a different accessory device using a high-speed Type-C data line may have a signal disrupted due to the impact of an inductor in the GND, interference may occur between a digital line of an FM antenna and an FM analog signal of the GND, and a high-speed USB 3.0 device may undergo deterioration in analog characteristics due to lack of a DC GND.

An electronic device according to various embodiments may provide a device and a method for receiving a broadcast signal using a connection to an external antenna configured by employing a sideband user (SBU) line of a Type-C connector and separating a GND.

An electronic device according to various embodiments may provide a device and a method for receiving a broadcast signal by connecting to an external antenna with a configuration in which a first ground pin of a Type-C connector is connected to a GND through a bead or an inductor and a second ground pin is directly connected to the GND.

An external antenna device according to various embodiments may provide a device and a method for receiving a broadcast signal by connecting to an electronic device with a configuration in which a first ground pin of a Type-C connector is connected to a GND through a bead or an inductor and a second ground pin is directly connected to the GND.

The connection interface may: be connected to the antenna using a specified first pin among the plurality of pins, at least a portion of the antenna being connected to at least one ground part; transmit a signal obtained via the antenna to the external electronic device through the first pin; and obtain sound information corresponding to the signal from the external electronic device using a specified second pin among the plurality of pins and emit a sound corresponding to the obtained sound information to the outside through the speaker.

An electronic device according to various embodiments may include a broadcast reception module, a connector configured to include a first ground pin, a second ground pin, and a data pin, a bead or an inductor configured to be connected to the first ground pin and the ground and to block a broadcast signal of a ground line from flowing to the ground, and a processor. The processor may be configured to: identify a type of an external electronic device through the connector; drive the broadcast reception module with an external antenna included in the external electronic device and the broadcast reception module electrically connected through the first ground pin when the type of the external electronic device corresponds to a specified electronic device type; receive a broadcast signal using the broadcast reception module from the external antenna; and output an audio signal generated based at least partly on the received broadcast signal to a specified device through the data pin.

A broadcast signal reception method of an electronic device according to various embodiments may include: identifying, through a first pin, a type of an external electronic device connected through a connector including the first pin and a second pin; driving a broadcast reception module with an external antenna included in the external electronic device and the broadcast reception module electrically connected through the first pin when the type of the external electronic device corresponds to a specified electronic device type; receiving a broadcast signal using the broadcast reception module from the external antenna; and outputting an audio signal generated based at least partly on the broadcast signal to a specified device through the second pin.

Advantageous Effects of Invention

In a Type-C connector of an electronic device, an SBU line is used as an AUX line of a display port (DP). The AUX line may be used to transmit an audio signal at a low-frequency of 1 Mhz or lower. Therefore, the AUX line is distant from a frequency domain of FM and DMB broadcast signals, thus facilitating filtering, and may be less sensitive than a USB digital line. In addition, since the GND of the electronic device does not change, characteristics of the electronic device and an external device connected to the electronic device may not be affected.

According to a method in which an electronic device receives a broadcast signal by connecting to an earphone antenna device through a Type-C connector according to various embodiments, it is possible to minimize the impact of USB characteristics by separating a GND line of the electronic device, and a Type-C earphone antenna device can also receive a broadcast signal while maintaining USB Type-C performance and usability.

Referring to FIG. 4, an external antenna device may include a connector 410, an antenna 420, a signal processing module 430, a microphone 440, and a speaker 450.

The connector 410 (e.g., the connector 20-9 of FIG. 2) may be electrically or physically coupled with a connector (e.g., the connector 201-9 of FIG. 2 or the connector 360 of FIG. 4) of an electronic device to enable connection to the electronic device.

The connector 500 may include a plurality of pins. According to various embodiments, the connector 500 may include a plurality of pins (e.g., A pins) on an A surface corresponding to the forward direction and a plurality of pins (e.g., B pins) on a B surface corresponding to the reverse direction. For example, the plurality of A pins may include a GND pin 511a, an SSTXp1 pin 512a, an SSTXn1 pin 513a, a VBUS pin 514a, a CC pin 515a, a Dp1 pin 516a, a Dn1 pin 517a, an SBU1 pin 518a, a VBUS pin 519a, an SSRXn2 pin 520a, an SSRXp2 pin 521a, and a GND pin 522a. For example, the plurality of B pins may include a GND pin 511b, an SSTXp1 pin 512b, an SSTXn1 pin 513b, a VBUS pin 514b, a VCONN pin 515b, a Dp1 pin 516b, a Dn1 pin 517b, an SBU1 pin 518b, a VBUS pin 519b, an SSRXn2 pin 520b, an SSRXp2 pin 521b, and a GND pin 522b.

The plurality of A pins may include one or more first ground pins, for example, the GND pins 511a and 522a, and one or more A pins, for example, the SSTXp1 pin 512a, the SSTXn1 pin 513a, the VBUS pin 514a, the CC Pin 515a, the Dp1 pin 516a, the Dn1 pin 517a, the SBU1 pin 518a, the VBUS pin 519a, the SSRXn2 pin 520a, and the SSRXp2 pin 521a, and the plurality of B pins may include one or more second ground pins, for example, the GND pins 511b, 522b, and one or more B pins, for example, the SSTXp2 pin 512b, the SSTXn2 pin 513b, the VBUS pin 514b, the VCONN pin 515b, the Dp1 pin 516b, the Dn1 pin 517b, the SBU2 pin 518b, the VBUS pin 519b, the SSRXn1 pin 520b, and the SSRXp1 pin 521b.

Referring to FIG. 5B, the SSTXp1 pin and SSTXp2 pin 512a and 512b and the SSTXn1 pin and SSTXn2 pin 513a and 513b may be pins for super-speed transmission (TX) enabling fast data transmission, the Vbus pins 514a and 514b may be pins for USB cable charging power, the CC pin 515a may be a pin serving as an identification terminal, the Vconn pin 515b may be a pin for supporting power, the Dp1 pins 516a and 516b and the Dn1 pins 517a and 517b may be pins for different bidirectional USB signals, the SBU1 pin and SBU2 pin 518a and 518b may be spare pins which may be used for various signals (e.g., an audio signal, a display signal, or the like), and the SSRXn2 pin and the SSRXn1 pin 520a and 520b and the SSRXp2 pin and the SSRXp1 pin 521a and 521b may be pins for super-speed reception (RX) enabling fast data reception.

When receiving a broadcast signal, an electronic device according to various embodiments may implement an antenna (e.g., FM antenna) function by connecting an SBU pin of a USB Type-C connector and separating a GND. An SBU may be a line formed for use in different applications other than a main data line in a USB Type-C connector. Regarding a GND, a USB Type-C GND may be separated to minimize impact on high-speed USB communication.

The electronic device uses an SBU line as a DP AUX line. The AUX line may transmit an audio signal at a low frequency of 1 MHz or lower. Therefore, the AUX line is distant from a broadcast (e.g. FM or DMB) frequency domain, thus facilitating filtering, and may be less sensitive than a USB digital line. In addition, since the GND of the electronic device does not change, characteristics of the electronic device and an external antenna device may not be affected. A method using a GND may minimize the impact of USB characteristics by separating a GND line of an electronic device. Since USB Type-C enables reverse connection, GND may be designed in a pair (first ground and second ground).

FIG. 6 illustrates an example of the configuration of an electronic device according to various embodiments.

Referring to FIG. 6, the electronic device (e.g., the electronic device 101 of FIG. 1, the electronic device 201 of FIG. 2, or FIG. 3) may include a processor 610, an FM reception module 620, a DMB reception module 623, an IF PMIC 630, an AUX switch 640, a broadcast selection switch 625, a low-noise amplifier (LNA) 627, a signal blocking circuit 650, and a connector 660. A connector 670 may be a connector of an external antenna device.

The connector 660 in a Type-C form may have the same structure as that illustrated in FIG. 5A and may have the same pin characteristics as those illustrated in FIG. 5B. An antenna (e.g., the antenna 420 of FIG. 4) of the external antenna device may be connected to an SBU1 pin and an SBU2 pin of the connector 670. The SBU1 pin and the SBU2 pin of the connector 660 may be connected to the IF PMIC 630, the AUX switch 640, and the LNA 6237 through the signal blocking circuit 660.

The signal blocking circuit 650 (e.g., the signal block module 350 of FIG. 3) may include inductors 651 and 652 connected to respective SBU1 and SBU2 lines and the IF PMIC 630, inductors 653 and 654 connected to the respective SBU1 and SBU2 lines and the AUX switch 640, capacitors 655 and 656 connected to the respective SBU1 and SBU2 lines and the LNA 627, and electrostatic discharge (ESD) diodes 657 and 658 connected to the respective SBU1 and SBU2 lines and the ground. The inductors 651 and 652 may block broadcast signals of the SBU1 and SBU2 lines from being applied to the IF PMIC 630, and the inductors 653 and 654 may block the broadcast signals of the SBU1 and SBU2 lines from being applied to the AUX switch 640. The capacitors 655 and 656 may perform DC blocking so that a signal of an AUX line is not applied to the LNA 627. The ESD diodes 657 and 658 may perform a function of ESD protection of the SBU1 and SBU2 lines.

The IF PMIC 630 (e.g., the connection detection module 310 of FIG. 3) may detect water infiltrating into the Type-C connector in a state where the Type-C connector 670 is not connected to the connector 660. The IF PMIC 630 may perform a CCIC function when the Type-C connector 670 is connected to the connector 660.

The AUX switch 640 may perform AUX switching when the connector 670 is reversibly connected to the connector 660.

The FM reception module 620, the DMB reception module 623, and the broadcast selection switch 625 may be a broadcast reception module (e.g., the broadcast reception module 340 of FIG. 4). The broadcast reception module may include both FM and DMB or may include only one broadcast thereof. In addition, the broadcast reception module may include broadcasts (e.g., an Internet mobile TV or the like) other than FM and DMB. The broadcast reception module may further include a low-noise amplifier (LNA) 627 to perform low-noise amplification of a received broadcast signal and to apply the broadcast signal to the broadcast selection switch 625.

The processor 610 may be an application processor (AP). The processor 610 may receive signals from the IF PMIC 630, the AUX switch 640, the FM reception module 620, and the DMB reception module 623. When the connector 670 is not connected to the connector 660 (no external device is connected to the Type-C connector), the IF PMIC 630 is in an enabled state, and the processor 610 may determine whether water infiltrates into the connector, based on an output from the IF PMIC 630. When the connector 670 is connected to the connector 660, the processor 610 may recognize the product ID (PID) of a connected external device, based on a CCIC. Here, when the connected external device is a DP, the processor 610 may control the AUX switch 640 to be turned on and the IF PMIC 630 and the broadcast selection switch 625 to be turned off.

When the connected external device is an external antenna device, the processor 610 may turn off the IF PMIC 630 and the AUX switch 640 and may analyze an executed broadcast. When the executed broadcast is an FM broadcast, the processor 610 may control the broadcast selection switch 625 to perform switching connection of an output from the LNA 627 to the FM reception module 620. Then, an FM broadcast signal received by the antenna of the external antenna device may be transmitted to the LNA 627 through the SBU pins of the connector 670 and the SBU pins of the connector 660, and the FM broadcast signal, which has been low-noise amplified by the LNA 627, may be processed by the FM reception module 620 through the broadcast selection switch 625. Alternatively, when the executed broadcast is a DMB broadcast, the processor 610 may control the broadcast selection switch 625 to perform switching connection of an output from the LNA 627 to the DMB reception module 623. Then, a DMB broadcast signal received by the antenna of the external antenna device may be transmitted to the LNA 627 through the SBU pins of the connector 670 and the SBU pins of the connector 660, and the DMB broadcast signal, which has been low-noise amplified by the LNA 627, may be processed by the DMB reception module 623 through the broadcast selection switch 625.

The electronic device may process DP AUX and broadcast reception functions in common, based on the USB Type-C connector. In the configuration illustrated in FIG. 6, the operating state of each component may be illustrated below in Table 1.

FIG. 7A and FIG. 7B illustrate an example of using an SBU line of a Type-C connector as an antenna according to various embodiments.

Referring to FIG. 7A and FIG. 7B, an electronic device 700 (e.g., the electronic device 101 of FIG. 1, the electronic device 201 of FIG. 2, or FIG. 3) may include an FM reception module 710 (e.g., the broadcast reception module 340 of FIG. 3 or the FM reception module 620 in FIG. 6) and a Type-C connector 720 (e.g., the connection terminal 178 of FIG. 1, the connector 201-9 of FIG. 2, the connector 360 of FIG. 3, FIG. 5A, or the connector 660 of FIG. 6). An external antenna device 750 (e.g., the electronic device 102 of FIG. 1 or FIG. 4) may include a connector (e.g., the connector 20-9 of FIG. 2, the connector 410 of FIG. 4, FIG. 5A, or the connector 670 of FIG. 6) and an antenna 770 (e.g., the antenna 420 of FIG. 4).

Referring to FIG. 7A, the electronic device 700 and the external antenna device 750 may use an SBU line as an antenna. The antenna 770 of the external antenna device 750 may be connected to SBU1 and SBU2 pins of the connector 760. Further, a first ground pin and a second ground pin (e.g., in FIG. 5A, the first ground pin may be GND A1 and GND B1, and the second ground pin may be GND A12 and GND B12) of the connector 760 may be directly connected to the ground. When the connector 760 of the external antenna device 750 is connected to the connector 720 of the electronic device 700, SBU1 and SBU2 pins of the connector 760 and the connector 720 are connected, and thus an FM signal received by the antenna 770 may be applied to the FM reception module 710 through SBU1 and SBU2 lines.

Referring to FIG. 7B, the electronic device 700 and the external antenna device 750 may use a first ground line and an SBU line as an antenna.

A first ground pin (e.g., in FIG. 5A, the first ground pin includes GND A1 and GND B1 pins) of the connector 760 may be connected to SBU1 and SBU2 lines and may be connected to the ground through a blocking element. The blocking element may be connected to the first ground pin and a ground part and may function to block a broadcast signal applied to a first ground line from being applied to the ground part. The blocking element may be configured as a bead or inductor. In the following description, a bead is illustrated as an example of the blocking element. As illustrated in FIG. 7B, the first ground pin of the connector 760 may be connected to the SBU1 and SBU2 lines and may be connected to the ground through the bead 780. A second ground pin (e.g., GND A12 and GND B12 pins in FIG. 5A) of the connector 760 may be directly connected to the ground. Therefore, since the first ground lines are separated from the ground by the bead 780 to be connected to the SBU1 and SBU2 lines, the SBU lines and the first ground line may be used as an antenna. When the connector 760 of the external antenna device 750 is connected to the connector 720 of the electronic device 700, SBU1 and SBU2 pins of the connector 760 and the connector 720 are connected, and an FM signal received by the antenna 770 may be applied to the FM reception module 710 through the first ground line and the SBU1 and SBU2 lines.

FIG. 10A to FIG. 10C illustrate an example of using a ground line of a Type-C connector as an antenna according to various embodiments.

Referring to FIG. 10A to FIG. 10C, an electronic device 1000 (e.g., the electronic device 101 of FIG. 1 of FIG. 1, the electronic device 201 of FIG. 2, or FIG. 3) may include an FM reception module 1010 (e.g., the broadcast reception module 340 of FIG. 3 or the FM reception module 620 of FIG. 6), a Type-C connector 1020 (e.g., the connection terminal 178 of FIG. 1, the connector 201-9 of FIG. 2, the connector 360 of FIG. 3,

FIG. 5A, or the connector 660 of FIG. 6), a varistor 1030, and a bead 1040.

An external antenna device 1050 (e.g., the electronic device 102 of FIG. 1 or FIG. 4) may include a connector (e.g., the connector 20-9 of FIG. 2, the connector 410 of FIG. 4, FIG. 5A, or the connector 670 of FIG. 6), an antenna 770 (e.g., the antenna 420 of FIG. 4), and a bead 1080 and 1085.

Referring to FIG. 10A to FIG. 10C, the beads 1040, 1080, and 1085 may be a blocking element connected to a ground pin and the ground part. The blocking element may serve to block a broadcast signal of a ground line connected to the ground pin from being applied to the ground part. The blocking element may be configured with a bead or an inductor. In the following description, a bead is used as a blocking element.

Referring to FIG. 10A, the ground of the electronic device may be connected to the ground through the bead 104, and the ground of the external antenna device 1050 may be used as an antenna. The FM reception module 1010 of the electronic device may be connected to a ground pin of the connector 1020 through the varistor 1030, and a ground line of the connector 1020 may be connected to the ground through the bead 1040. The antenna 1070 of the external antenna device 1050 may be connected to a ground pin of the connector 1060, and the ground pin may be connected to a PCB ground of the external antenna device. When the connector 1060 of the external antenna device 1050 is connected to the connector 1020 of the electronic device 1000, the ground pins of the connector 1060 and the connector 1020 are connected, and thus an FM signal received through the antenna 1070 may be applied to the FM reception module 1010 through the ground line.

The ground pin of the electronic device 1000 may be connected to the ground through the bead. The ground pin of the external antenna device may be directly connected to the ground of the electronic device, and thus a ground line of the external antenna device may be used as an antenna.

Referring to FIG. 10B, a ground line of the electronic device may be divided, wherein a first ground line may be connected to the ground through the bead 1080, and a second ground line may be directly connected to the ground so that a ground line and a plane of the external antenna device may be used as an antenna for broadcast reception.

A first ground pin (e.g., in FIG. 5A, the first ground pin is the GND A1 and GND B1 pins) of the connector 1060 may be connected to the antenna 170 and may be connected to the ground through the bead 1080. A second ground pin (e.g., the GND A12 and GND B12 pins in FIG. 5A) of the connector 1060 may be directly connected to the ground. Accordingly, since the first ground lines are separated from the ground by the bead 1080 and are connected to the antenna 1070, the first ground lines may be used as an antenna. When the connector 1060 of the external antenna device 1050 is connected to the connector 1020 of the electronic device 1000, an FM signal received through the antenna 1070 may be applied to the FM reception module 1010 through the first ground line.

A ground line of a terminal may be divided, wherein a first ground line may be connected to the ground through a bead, and a second ground line may be directly connected to the ground. Therefore, the external antenna device may use the ground line and a plane as an antenna.

Referring to FIG. 10C, a ground line of the electronic device may be divided, wherein a second ground line may be connected to the ground through the bead 1085, and a ground line may be directly connected to the ground so that a ground line and a plane of the external antenna device may be used as an antenna for broadcast reception.

A second ground pin (e.g., in FIG. 5A, the second ground pin is the GND A12 and GND B12 pins) of the connector 1060 may be connected to the antenna 170 and may be connected to the ground through the bead 1080. A first ground pin (e.g., the GND A1 and GND B1 pins in FIG. 5A) of the connector 1060 may be directly connected to the ground. Accordingly, since the second ground lines are separated from the ground by the bead 1085 and are connected to the antenna 1070, the first ground lines may be used as an antenna. When the connector 1060 of the external antenna device 1050 is connected to the connector 1020 of the electronic device 1000, an FM signal received through the antenna 1070 may be applied to the FM reception module 1010 through the second ground line.

A ground line of a terminal may be divided, wherein a first ground line may be connected to the ground through a bead, and a second ground line may be directly connected to the ground. The external antenna device may use the ground line as an antenna.

FIG. 11 illustrates an example in which an electronic device and an external antenna device configure an FM antenna through a ground line of a Type-C connector according to various embodiments. FIG. 11 illustrates an example of configuring a first ground line as an antenna as in FIG. 10C.

Referring to FIG. 11, the electronic device (e.g., the electronic device 101 of FIG. 1, the electronic device 201 of FIG. 2, or FIG. 3) may include a processor 1110, a codec 1115, an FM reception module 1120, a broadcast selection switch 1125, a low-noise amplifier (LNA) 1127, a connector 1160, and a bead 1140. The configuration of the electronic device of FIG. 11 may be a structure in which a DMB reception module, an IF PMIC, an AUX switch, and a signal blocking circuit are omitted from the configuration of the electronic device of FIG. 6. In FIG. 11, a connector 1170 may be a connector of the external antenna device. In the configuration of the electronic device, the codec 1115 may be included in the processor 1110. The external antenna device (e.g., FIG. 4) may include a codec 810, an antenna 820, and a connector 830.

A first ground pin (GND A1 and GNS B1) of the connector 1160 of the electronic device may be connected to the ground through the bead 1140 and may be connected to the LNA 1127 through a varistor not shown. A second ground pins (GND A12 and GNS B12) of the connector 1160 may be directly connected to the ground.

The codec 1190 (e.g., the signal processing module 430 of FIG. 4) of the external antenna device may be connected to a D+ pin and a D− pin of the connector 1194 (e.g., the connector 20-9 of FIG. 2, the connector 410 of FIG. 4, or FIG. 5) and may process a broadcast signal of the electronic device received through the connector 1194 to output the broadcast signal to a speaker (the speaker 450 of FIG. 4). The antenna 1192 (the antenna 420 of FIG. 4) may be connected to a first ground pin (GND A1 and GND B1 pins) of the connector 1194, and the first ground pin (GND A1 and GND B1 pins) may be connected to the ground through a bead 1196. A second ground pin (GND A12 and GND B12 pins) of the connector 1194 may be directly connected to the ground.

When the connector 1194 and the connector 1160 are connected, a broadcast signal (e.g., an FM signal) received through the antenna 1192 may be applied to the FM reception module 1120 of the electronic device through a first ground line, as indicated by a bold solid line. The FM broadcast signal may be applied to the processor 1110 via the FM reception module 1120 and the codec 1115. The processor 1110 may apply the FM signal, received from the external antenna device, to D+ and D− pins of the connector 1160. The FM signal applied to the connector 1160 may be applied to the codec 1190 of the external antenna device through the D+ and D-pins of the connector 1194. The FM signal processed by the electronic device may have a processing path indicated by a bold dotted line.

FIG. 11 illustrates an example in which the first ground line is used as an antenna by connecting the first ground pin (GND A1 and GND B1) of the connector 1160 of the electronic device and the first ground pin (GND A1 and GND B1) of the connector 1194 of the external antenna device to the ground through the bead 1140 and the bead 1196, respectively, and connecting the second ground pin (GND A12 and GND B12) of the connector 1160 and the second ground pin (GND A12 and GND B12) of the connector 1194 of the external antenna device directly to the ground. Alternatively, a second ground line may be used as an antenna by connecting the first ground pin (GND A1 and GND B1) of the connector 1160 of the electronic device and the first ground pin (GND A1 and GND B1) of the connector 1194 of the external antenna device directly to the ground and connecting the second ground pin (GND A12 and GND B12) of the connector 1160 and the second ground pin (GND A12 and GND B12) of the connector 1194 of the external antenna device to the ground through the respective beads. The bead 1140 and the bead 1196 may be replaced with inductors.

The broadcast reception module may be an FM broadcast reception module.

An electronic device according to various embodiments may include: at least one speaker configured to emit a sound; an antenna; and a connection interface configured to be electrically connected to the antenna and to include a plurality of pins for connecting to an external electronic device. The connection interface may: be connected to the antenna using a first ground pin connected to a ground part through a bead among the plurality of pins; transmit a signal obtained via the antenna to the external electronic device through the first ground pin; and obtain sound information corresponding to the signal from the external electronic device using a data pin and emit a sound corresponding to the obtained sound information to the outside through the speaker.

The connection interface may be a Type-C plug connector. In the connection interface, a first ground line connected to the first ground pin and a PCB plane may be connected to the ground part through the bead or an inductor, and a second ground pin may be directly connected to the ground part.

In the connection interface, the first ground line connected to the first ground pin may be connected to the ground part through the bead or the inductor, and the second ground pin may be directly connected to the ground part.

FIG. 12 is a flowchart illustrating a procedure in which an electronic device processes a signal received through an antenna using a Type-C connector according to various embodiments.

Referring to FIG. 12, when a connector (e.g., the connector 20-9 of FIG. 2, the connector 410 of FIG. 4, FIG. 5A, or the connector 670 of FIG. 6) is connected to a Type-C connector (e.g., the connection terminal 178 of FIG. 1, the connector 201-9 of FIG. 2, the connector 360 of FIG. 3, FIG. 5A, or the connector 660 of FIG. 6), an electronic device (e.g., the electronic device 101 of FIG. 1, the electronic device 201 of FIG. 2, FIG. 3, or FIG. 6) may recognize a connected external device, based on a CCIC.

In a state where no connector is connected to the Type-C connector (idle state), the electronic device may turn on the CCIC (e.g., the IF PMIC 630 of FIG. 6) and may maintain a DP AUX switch (e.g., the AUX switch 640 of FIG. 6) and a broadcast switch (e.g., the broadcast selection switch 640 of FIG. 6) to be turned off in operation 1211. In the idle state, the electronic device may determine whether water infiltrates into the Type-C connector. When the connector is connected to the connector, the electronic device may recognize the connection of the connector in operation 1213 and may recognize the connected external device, based on the CCIC in operation 1215. For example, in operation 1215, the electronic device may analyze the PID of the connected external device, thereby recognizing the external device. When the connected external device corresponds to a DP PID, the electronic device may recognize the connection of a DP in operation 1217, may turn on the DP AUX switch, and may turn off the CCIC and the broadcast switch in operation 1219. The electronic device may process a DP signal received through SBU1 and SBU2 pins of the connector.

When an external antenna device with a Type-C connector is connected, the electronic device may recognize the connection of the external antenna device in operation 1221. When the connection of the external antenna device including the Type-C connector is recognized, the electronic device may analyze an application being executed in operation 1223. When the application being executed is a broadcast application, the electronic device may turn on the broadcast switch, may turn off the CCIC and the DP AUX switch, and may reproduce a broadcast signal in operation 1225. The broadcast signal may be an FM signal or a DMB signal. When the application being executed corresponds to multimedia playback, such as music or video playback, the electronic device may recognize multimedia playback in operation 1234 and may perform a multimedia playback service in operation 1229.

In one embodiment, an antenna of the external antenna device having the Type-C connector may be connected to an SBU pin, a first ground pin (e.g., GND A1 and GND B1), or a second ground pin (e.g., GND A12 and GND B12) of the connector, and first and second ground pins of the connector of the electronic device may be connected to the ground. When the antenna is connected to SBU1 and SUB2 pins, a broadcast signal may be received through the antenna including an SBU line (or a first ground line and the SBU line or a second ground line and the SBU line) and may be applied to an SBU line of the electronic device.

In one embodiment, the antenna of the external antenna device having the Type-C connector may be connected to the first ground pin (e.g., GND A1 and GND B1) and/or the second ground pin (e.g., GND A12 and GND B12) of the connector, and the first ground pin and/or the second ground pin of the connector of the electronic device may be connected to the ground through a bead. When the antenna is connected to the ground pins, a broadcast signal may be received through the antenna including the ground line (the first ground line and/or the second ground line) and may be applied to the SBU line of the electronic device.

When the external device connected to the Type-C connector of the electronic device is not a DP device or an external antenna device, the electronic device may recognize that a different external device is connected in operations 1217 and 1221 and may execute a service for the recognized external device in operation 1251.

The connector may be a Type-C socket connector. The receiving of the broadcast signal may include receiving the broadcast signal through a sideband use (SBU) pin as the first pin, and the outputting of the audio signal to the specified device may include outputting the audio signal through D+ and D− pins as the second pin.

The broadcast reception module may be an FM broadcast reception module.

The driving of the broadcast reception module may include connecting an output from the SBU pin of the socket connector to an FM reception module when the selected broadcast reception module is the FM reception module; and connecting the output from the SBU pin of the socket connector to a DMB reception module when the selected broadcast reception module is the DMB reception module.

FIG. 13A and FIG. 13B illustrate an example of configuring a broadcast antenna through an electronic device and a plurality of external antenna devices according to various embodiments.

Referring to FIG. 13A and FIG. 13B, the electronic device (e.g., the electronic device 101 of FIG. 1, the electronic device 201 of FIG. 2, or FIG. 3) may include a processor 1310, a codec 1315, an FM reception module 1320, a DMB reception module 1323, an IF PMIC 1330, an AUX switch 1340, a broadcast selection switch 1325, a low-noise amplifier (LNA) 1327, a signal blocking circuit 1350, a connector 1360, an antenna switch 1390, and a jack not shown. A connector 1370 may be a connector of a first external antenna device using a Type-C connector, and a jack 1380 may be a jack of a second external antenna device using a 3.5 phi connector.

In FIG. 13A, the electronic device may include the jack (not shown) to connect the Type-C connector 1360 and a 3.5 phi jack. The antenna switch 1390 may be connected to the connector 1360 and the jack. When the connector of the first external antenna device and the jack of the second external antenna device are connected respectively to the connector 1360 and the jack not shown of the electronic device, the processor 1310 may control the antenna switch 1390 to apply a broadcast signal, received through the connector 1360 or the jack, to the LNA 1327. The processor 1310 may control switching connection of the antenna switch 1390, based on a set priority. For example, when the Type-C connector and the 3.5 phi connector are connected at the same time, the processor 1310 may select the external antenna device in a Type-C connector mode.

In FIG. 13B, the electronic device may include the jack (not shown) to connect the Type-C connector 1360 and a 3.5 phi jack. In the electronic device, an output terminal of the Type-C connector 1360 and an output terminal of the 3.5 phi jack may be composed at an input terminal of the LNA 1327. When the connector of the first external antenna device and the jack of the second external antenna device are connected respectively to the connector 1360 and the jack not shown of the electronic device, broadcast signals output from the two antenna devices may be synthesized and input to the LNA 1327. Therefore, the Type-C connector and the 3.5 phi connector may be bridged to use both a Type-C connector line and a 3.5 phi connector line as antenna lines.

FIG. 13A and FIG. 13B illustrate an example in which an electronic device and a Type-C external device use an SBU line as an antenna. In a Type-C connector having a first ground pin and a second ground pin, one of two ground lines may be connected to the ground through a bead and the other ground line may be directly connected to the ground line, thereby using the ground lines of the Type-C connector as an antenna.

FIG. 14 illustrates an example of configuring a broadcast antenna using a 3.5 phi adaptor according to various embodiments.

Referring to FIG. 14, a 3.5 phi external antenna device may include a codec 1410, and an adaptor may include an antenna 1420 and a connector 1430. A 3.5 phi ground line may be connected to a first ground line or a second ground line of the Type-C connector 1430. For example, a first ground pin (GND A1 and GND B1 pins) may be connected to the ground through a bead 1440, and a second ground pin (GND A12 and GND B12 pins) may be directly connected to the ground. The 3.5 phi ground line (G) may be connected, through a line 1450, to the first ground line connected to the first ground pin (GND A1 and GND B1 pins). An electronic device and the 3.5 phi external antenna device configured as illustrated in FIG. 14 may receive a broadcast signal (e.g., an FM signal) through the first ground line of a Type-C adaptor.

FIG. 14 shows an example of configuring the first ground line of the adaptor as an antenna. Also, the first ground pin (GND A1 and GND B1 pins) may be directly connected to the ground, the second ground pin (GND A12 and GND B12 pins) may be connected to the ground through the bead, and the 3.5 phi ground line may be connected to the second ground pin (GND A12 and GND B12 pins). The electronic device and the 3.5 phi external antenna device may receive a broadcast signal (e.g., an FM signal) through the second ground line of a Type-C adaptor.

Although various embodiments have been illustrated, different modifications may be possible without departing from the scope of the various embodiments of the disclosure.
