The audio output unit 430 may convert audio data received by the radio frequency unit 410 or the network module 420 or stored in the memory 490 into an audio signal, and output the audio signal as a sound. In addition, the audio output unit 430 may further provide an audio output (for example, a call signal reception sound or a message reception sound) related to a specific function performed by the terminal 40. The audio output unit 430 includes a speaker, a buzzer, a telephone receiver, and the like.

The input unit 440 is configured to receive an audio or video signal. The input unit 440 may include a graphics processing unit (Graphics Processing Unit, GPU) 441 and a microphone 442. The graphics processing unit 441 processes image data of a still picture or a video obtained by an image capture apparatus (for example, a camera) in a video capture mode or an image capture mode. A processed image frame may be displayed on the display unit 460. An image frame processed by the graphics processing unit 441 may be stored in the memory 490 (or another storage medium) or sent by the radio frequency unit 410 or the network module 420. The microphone 442 may receive a sound and may process the sound into audio data. The processed audio data may be converted, in a telephone call mode, into a format that can be sent to a mobile communications network device through the radio frequency unit 410, for outputting.
