When the external device is a data line, the external device is generally connected with the active device through the data line, so that whether the external interface is connected with the data line or not can be judged by detecting the voltage value of the first pin of the external interface, and the purpose of accurately judging the type of the connected external device is achieved.
Example 3:

Therefore, if the central processing unit judges that the resistance value between the second pin and the third pin of the external interface is different from the stored resistance value of the external device which is not connected, the external interface is currently connected with the external device.
If the external interface is connected with the data line, the voltage value of the first pin of the external interface is larger than the preset first voltage value, and if the external interface is connected with the earphone, the voltage value of the first pin of the external interface is not changed, or even if the voltage value is changed, the change quantity of the voltage value does not reach the preset first voltage value, so that if the resistance value between the second pin and the third pin of the external interface is different from the stored resistance value of the unconnected external equipment, whether the acquired voltage value of the first pin of the external interface is larger than the preset first voltage value or not can be judged, and the type of the external equipment can be determined more accurately.

Therefore, the embodiment of the invention also comprises:

Example 5:
when the external device connected to the external interface is different, the resistance value between the second pin and the third pin of the external interface will be different, and on the basis of the above embodiments, in an embodiment of the present invention, the switch unit is specifically configured to obtain and send the resistance value between the second pin and the third pin of the external interface and the voltage value of the sixth pin, in order to further improve the accuracy of determining the type of the external device;
the central processing unit is specifically configured to determine whether the obtained resistance value between the second pin and the third pin of the external interface is the same as the stored resistance value of the unconnected external device; if not, judging whether the voltage value of the sixth pin is larger than a preset second voltage value, if so, determining that the external equipment is a data line, otherwise, determining that the external equipment is an earphone.
If the external interface of the mobile terminal is connected with the external device, the external device can be an earphone or a data line in the embodiment of the invention, so that the second pin and the third pin in the external interface are connected with the left and right sound channels or the data transmission line in the external device, and the resistance value between the second pin and the third pin of the external interface is changed. Therefore, if the central processing unit judges that the resistance value between the second pin and the third pin of the external interface is different from the stored resistance value of the external device which is not connected, the external interface is currently connected with the external device.
If the external interface is connected with the data line, the voltage value of the sixth pin of the external interface is larger than the preset second voltage value, and if the external interface is connected with the earphone, the voltage value of the sixth pin of the external interface is not changed, so that if the resistance value between the second pin and the third pin of the external interface is different from the stored resistance value of the external equipment which is not connected, the type of the external equipment can be more accurately determined by judging whether the acquired voltage value of the sixth pin of the external interface is larger than the preset second voltage value.
Example 6:

the central processing unit is specifically configured to send a control signal to the switch unit to control the normally closed end of the normally closed switch to be open and the normally open end to be closed if it is determined that the external device is a data line, and send a control signal to the switch unit to keep the normally closed end of the normally closed switch to be closed and the normally open end to be open if it is determined that the external device is an earphone.
Specifically, a normally closed end of the normally closed switch is connected to the audio unit, and a normally open end of the normally closed switch is connected to the central processing unit, when the central processing unit determines that the external device is a data line, the central processing unit sends a control signal to the switch unit to control the normally closed end of the normally closed switch to be opened and the normally open end to be closed, and performs read-write processing on data transmitted by the external device, and when the external device is determined to be an earphone, the central processing unit sends a control signal to the switch unit to keep the normally closed end of the normally closed switch closed and the normally open end to be opened, and performs audio processing on the data transmitted by the external device.
Because the central processing unit in the embodiment of the present invention may determine whether the currently connected external device is a data line according to the voltage value of the first pin and the voltage value of the sixth pin, if it is determined that the currently connected external device is a data line, the central processing unit may send a control signal to the switch unit to control the normally-closed end of the normally-closed switch to be opened and the normally-open end of the normally-closed switch to be closed, so that the central processing unit and the external device are connected to implement a read-write operation on data transmitted by the external device. If the earphone is connected or not at present can not be judged only according to the voltage value of the first pin and the voltage value of the sixth pin, but because the switch unit is a normally closed switch, the normally closed end is connected with the audio unit, and the normally open end is connected with the central processing unit, even if the external equipment connected with the external interface is the earphone at the moment, the external equipment can be directly connected with the audio unit, so that the audio processing of data transmitted by the external equipment is realized.
Certainly, the switch unit may also be a bidirectional switch, the bidirectional switch has two closed ends, the first closed end is connected to the central processing unit, the second closed end is connected to the audio unit, and when the bidirectional switch does not receive a control instruction of the central processing unit, the bidirectional switch is in an off state with both the first closed end and the second closed end, when the central processing unit determines that the external device is a data line, the bidirectional switch sends a control signal for controlling the first closed end to be closed to the switch unit, so that the central processing unit is connected to the external device, and performs read-write processing on data transmitted by the external device.
For the convenience of the user to use and the improvement of the user experience, on the basis of the above embodiments, the external interface is a 3.5mm interface.

The preset first voltage value may be determined according to a battery allowable voltage of the mobile terminal, for example, if the battery allowable voltage of the mobile terminal is 5V, the first voltage value may be 4.5V, 4.6V, or the like, as long as the voltage of the data line connected to the external interface can be detected.
When the external device is a data line, the external device is generally connected with the active device through the data line, so that whether the external interface is connected with the data line or not can be judged by detecting the voltage value of the first pin of the external interface, and the purpose of accurately judging the type of the connected external device is achieved.
Example 9:
in the above embodiment, when the external interface is connected to the data line, the voltage value of the first pin of the external interface is greater than the preset first voltage value, if the external interface is connected to the earphone, the voltage value of the first pin of the external interface is not changed, or even if the voltage value is changed, the change amount of the voltage value does not reach the preset first voltage value, and when the external interface is connected to the external device, the resistance value between the second pin and the third pin of the external interface is different. Therefore, in the embodiment of the present invention, in order to more accurately determine the type of the external device connected to the external interface, the acquiring the state information of each pin of the external interface includes:
acquiring a voltage value of the first pin, and acquiring a resistance value between the second pin and the third pin;
the determining the type of the external device according to the state information of each pin includes:
judging whether the obtained resistance value between the second pin and the third pin of the external interface is the same as the stored resistance value of the unconnected external equipment or not;
if not, judging whether the acquired voltage value of the first pin of the external interface is larger than a preset first voltage value or not;
if so, determining that the external equipment is a data line, otherwise, determining that the external equipment is an earphone.
If the external interface of the mobile terminal is connected with the external device, the external device can be an earphone or a data line in the embodiment of the invention, so that the second pin and the third pin in the external interface are connected with the left and right sound channels or the data transmission line in the external device, and the resistance value between the second pin and the third pin of the external interface is changed. Therefore, if the resistance value between the second pin and the third pin of the external interface is different from the stored resistance value of the external device which is not connected, the external interface is currently connected with the external device.
If the external interface is connected with the data line, the voltage value of the first pin of the external interface is larger than the preset first voltage value, and if the external interface is connected with the earphone, the voltage value of the first pin of the external interface is not changed, or even if the voltage value is changed, the change quantity of the voltage value does not reach the preset first voltage value, so that if the resistance value between the second pin and the third pin of the external interface is different from the stored resistance value of the unconnected external equipment, whether the acquired voltage value of the first pin of the external interface is larger than the preset first voltage value or not can be judged, and the type of the external equipment can be determined more accurately.
Example 10:
on the basis of the above embodiments, the external interface further includes a sixth pin, where the sixth pin is an identification ID pin of the external device.
The sixth pin is an identification ID pin of the external device, and if the external device is connected to the external interface, the mobile terminal may obtain identification information of the external device through the sixth pin, where the identification information is information that uniquely identifies the external device and may be a device number of the external device.
Specifically, after the external device is connected to the external interface, the mobile terminal may communicate with the external device through the sixth pin, obtain identification information of the external device, and determine the type of the external device according to the identification information of the external device.
The mobile terminal communicates with the external device, and acquiring the identification information of the external device is the prior art, and the process is not described in detail in the embodiment of the invention.
In addition, the mobile terminal may also obtain a voltage value of the sixth pin, where if the external device is a data line, the voltage value is greater than a set second voltage value, and if the external device is an earphone, the voltage value is not changed, and the second voltage value may be 1V, or may be a voltage value that can identify that the external interface is connected to the data line, such as 1.5V. Therefore, in the embodiment of the present invention, the acquiring the status information of each pin of the external interface further includes:
acquiring a voltage value of the sixth pin;
judging whether the acquired voltage value of the sixth pin of the external interface is larger than a preset second voltage value or not; if so, determining that the external equipment is the data line.
Example 11:
when the external device connected to the external interface is different, the resistance value between the second pin and the third pin of the external interface will be different, and in order to further improve the accuracy of determining the type of the external device, on the basis of the above embodiments, in an embodiment of the present invention, the acquiring the state information of each pin of the external interface further includes:
acquiring a voltage value of the sixth pin, and acquiring a resistance value between the second pin and the third pin;
the determining the type of the external device according to the state information of each pin includes:
judging whether the obtained resistance value between the second pin and the third pin of the external interface is the same as the stored resistance value of the unconnected external equipment or not;
if not, judging whether the voltage value of the sixth pin is larger than a preset second voltage value or not;
if so, determining that the external equipment is a data line, otherwise, determining that the external equipment is an earphone.
If the external interface of the mobile terminal is connected with the external device, the external device can be an earphone or a data line in the embodiment of the invention, so that the second pin and the third pin in the external interface are connected with the left and right sound channels or the data transmission line in the external device, and the resistance value between the second pin and the third pin of the external interface is changed. Therefore, if the resistance value between the second pin and the third pin of the external interface is different from the stored resistance value of the external device which is not connected, the external interface is currently connected with the external device.
If the external interface is connected with the data line, the voltage value of the sixth pin of the external interface is larger than the preset second voltage value, and if the external interface is connected with the earphone, the voltage value of the sixth pin of the external interface is not changed, so that if the resistance value between the second pin and the third pin of the external interface is different from the stored resistance value of the external equipment which is not connected, the type of the external equipment can be more accurately determined by judging whether the acquired voltage value of the sixth pin of the external interface is larger than the preset second voltage value.
