In one embodiment, the touch panel 731 can include two portions, a touch measurement device and a touch controller. The touch measuring device measures the touch direction of a user, measures signals brought by touch operation and transmits the signals to the touch controller; the touch controller receives touch information from the touch measurement device, converts it to touch point coordinates, and sends it to the processor 780, where it can receive commands from the processor 780 and execute them. In addition, the touch panel 731 may be implemented by various types, such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave.

Although the touch panel 731 and the display panel 741 are two independent components in fig. 7 to implement the input and output functions of the mobile phone, in some embodiments, the touch panel 731 and the display panel 741 may be integrated to implement the input and output functions of the mobile phone.

The mobile phone may be provided with other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor.

Audio circuitry 760, speaker 761, and microphone 762 may provide an audio interface between a user and a cell phone. The audio circuit 760 can transmit the electrical signal converted from the received audio data to the speaker 761, and the electrical signal is converted into a sound signal by the speaker 761 and output; on the other hand, the microphone 762 converts the collected sound signal into an electrical signal, converts the electrical signal into audio data after being received by the audio circuit 760, and then outputs the audio data to the processor 780 for processing, and then the audio data may be transmitted to another mobile phone through the antenna assembly 710, or outputs the audio data to the memory 720 for subsequent processing.

WIFI belongs to short-distance wireless transmission technology, and the mobile phone can help a user to receive and send electronic mails, browse webpages, access streaming media and the like through the WIFI module 770, and provides wireless broadband internet access for the user. Although fig. 7 illustrates the WIFI module 770, it can be understood that the antenna assembly includes a radiation segment of the WIFI frequency band, that is, the fourth radiator 223 or the first parasitic radiator 226 or the second parasitic radiator 227, and the radiators can implement signal transceiving of the WIFI frequency band, so the WIFI module 770 does not belong to an essential component of the mobile phone 700 and can be omitted as needed.

The processor 780 is a control center of the mobile phone, connects various parts of the entire mobile phone by using various interfaces and lines, and performs various functions of the mobile phone and processes data by operating or executing software programs and/or modules stored in the memory 720 and calling data stored in the memory 720, thereby integrally monitoring the mobile phone.
