Problems solved by technology
[0005] However, if the video output signal of the image, the audio output signal of the sound, and the audio input signal of the microphone are transmitted on a mobile phone in the above-mentioned manner, it is necessary to carry different types of connecting wires, which will cause great inconvenience to the user.
At the same time, due to the continuous shrinking of the size of mobile phones, the method of making two connection sockets in one mobile phone will inevitably occupy a lot of space, and will inevitably compress the space of other electronic components, thereby increasing the restrictions on many specifications

The invention discloses a portable electronic device and a connector connecting method for the same. The portable electronic device comprises a connecting seat, a processing circuit and a switch module. When a connector is inserted into the connecting seat, the processing circuit reads a voltage value of the connector through the switch module. When the processing circuit judges that the voltage value of the connector falls in a first voltage section, the processing circuit outputs a proper switching signal to the switch module so as to make an input signal of the connector transmitted to theprocessing circuit through the connecting seat and the switch module; and when the processing circuit judges that the voltage value of the connector falls in a second voltage section, the processing circuit outputs another switching signal to the switch module so as to make an output signal of the processing circuit transmitted to the connector through the connecting seat and the switch module.
Description
technical field [0001] The present invention relates to a portable electronic device and a connector connection method for the portable electronic device; in particular, it relates to a portable electronic device that only needs a single connector (connector) to transmit output signals or input signals. A portable electronic device and a joint connection method for the portable electronic device. Background technique [0002] With the advancement of technology, various electronic products have become an indispensable tool for modern people. These electronic products can not only help users handle various complex tasks, but also provide various entertainment functions, such as watching movies, listening to music, or voice services for network communication. What's more, in order to allow users to enjoy audio-visual entertainment while commuting or going out for leisure, portable electronic products with audio-visual functions have been developed in recent years, such as mobi...
