The present invention relates to an apparatus and method for listening to audio and radio in a mobile communication terminal, and more particularly, to an apparatus and method for automatically adjusting audio and radio signals.

In general, a mobile communication terminal has been developed as a device for moving and performing communication, and many additional functions have been added and used. To illustrate this example, alarm functions, text service functions, and functions for reproducing and listening to radio and audio signals have been added, and are currently used as multifunctional devices. The configuration and operation of the conventional mobile phone device manufactured to receive and listen to radio and audio signals in the mobile communication terminal will be described with reference to FIG. 1.

The controller 111 controls overall operations of the mobile communication terminal, and in particular, performs control according to listening to a radio signal and reproduction of audio data. The duplexer 112 has a built-in separator that separates and receives a radio signal and a mobile communication signal, and outputs the radio signal to the radio receiver 117. In addition, the duplexer 112 distinguishes a signal transmitted from a mobile communication terminal and a received signal, and outputs a signal to be transmitted from the transmitter 113 through an antenna ANT, and a signal received from the antenna ANT is a receiver. Output to (115). The transmitter 113 converts a signal of the transmission band using a signal output from the voice processor 118 and a signal received from the frequency synthesizer 114 and outputs the signal to the duplexer 112. The receiver 115 converts a signal received from the duplexer 112 into a signal of a predetermined band using a signal output from the frequency synthesizer 114 and then outputs the signal to the voice processor 116. The frequency synthesizer 114 generates and outputs frequencies to be output to the transmitter 113 and the receiver 115 under the control of the controller 111. In addition, the voice processing unit 116 codes an electric voice signal received from the microphone MIC under the control of the control unit 111 and outputs the encoded audio signal to the transmitting unit 113. The volume control unit decodes the signal received from the receiving unit 115. Output to (118).

The radio receiver 117 controls the on / off operation of the radio and the frequency of the reception band by the control signal CTL1 received from the control unit 111, and converts the radio band signal into an electrical voice signal during the radio on operation. To the volume control unit 118. The audio processor 119 reads audio data from the audio memory 120, converts the data into electrical voice data, and outputs the data to the volume controller 118 under the control of the controller 111. At this time, the data stored in the audio memory 120 is data such as the MP3 (MP3), the audio processing unit 119 may be configured as a DSP having an algorithm for processing such MP3 data. The volume controller 118 varies the magnitude of the electrical voice signal received from the radio receiver 117, the voice processor 118, and the audio processor 119 by the control signal CTL2 received from the controller 111. Output to speaker (SPK). Then, the speaker SPK adjusts the volume according to the magnitude of the electrical voice signal and outputs the audible sound. The memory unit 121 temporarily stores data necessary for a control operation of the control unit 111 and data generated during control, and the key input unit 122 generates a key signal corresponding to a key pressed by the user to the control unit 111. Output The display unit 123 displays the current state of the mobile communication terminal under the control of the control unit 111 or displays an operation process being performed.

As described above, at present, the mobile communication terminal can be used to listen to the radio, and the MP3 data can be used to listen to music and the like. However, the mobile communication terminal automatically cuts off a radio or audio signal when a call is received or a call is made when listening to music while listening to radio or using MP3 data, or when receiving a radio or audio signal at the same time. Is configured to listen at the same volume as when listening. Therefore, there was a problem that the call is interrupted by using the volume value of the level of listening to audio or radio only during the call. In addition, when the volume is adjusted, the signal output from the voice processor 116 along with the signals output from the radio receiver 117 and the audio processor 119 are varied, which is very inconvenient during a call.

Accordingly, an aspect of the present invention is to provide an apparatus and a method for automatically adjusting only the radio or audio listening signal that is being listened to when a call is received in a mobile communication terminal.

2 is a block diagram of a mobile communication terminal for listening to radio and audio signals according to a preferred embodiment of the present invention. Hereinafter, the configuration and operation of a mobile communication terminal according to the present invention will be described in detail with reference to FIG. 2.

The control unit 111 performs the overall operation of the mobile communication terminal, and in particular, performs control for automatically adjusting the volume of the radio and audio during a call according to the present invention together with the control according to the reproduction of the radio and audio. The duplexer 112, the transmitter 113, the frequency synthesizer 114, and the receiver 115 are configured as a wireless unit for voice call and data transmission and reception of a mobile communication terminal. In particular, the duplexer 112 is as shown in FIG. 1. A separator for distinguishing and outputting a radio signal to the radio receiver 117 is provided. The radio receiver 117 selects an on / off operation of the radio and a frequency band to be received under the control of the controller 111, converts the radio signal into an electrical voice signal, and outputs the radio volume to the radio volume controller 124 according to the present invention. .

The voice processing unit 116 decodes the signal received from the receiving unit 115, converts it into an electric voice signal, and adjusts the voice volume. Output to section 118.

The audio processor 119 reads and converts MPEG-3 data stored in the audio memory 120 under the control of the controller 111, converts the MPEG-3 data into an electrical voice signal, and outputs the converted audio signal to the audio volume controller 125. In addition, the audio memory 120 includes a semiconductor memory capable of reading and writing. The memory unit 121 stores data necessary for controlling the control unit 111, data generated during a control operation, and a volume value during a call of audio and radio signals according to the present invention, and simultaneously receives radio or audio when performing a call. Stores bits according to The key input unit 122 is composed of a key matrix such as a numeric key and a function key for dialing, and generates a key signal corresponding to a key pressed by the user and outputs it to the control unit 111. The display unit 123 includes a liquid crystal display panel or an LED, and displays an operation process of the mobile communication terminal or a current state of the mobile communication terminal.

3 is a control flowchart of adjusting audio reproduction volume in a mobile communication terminal according to an embodiment of the present invention. Hereinafter, a control process of audio reproduction volume control in a mobile communication terminal will be described in detail with reference to the block diagram of FIG. 2.

The controller 111 maintains the standby state in step 200. The waiting state refers to a state in which a call is received or a user waits for key input. The controller 111 proceeds to step 202 to check whether a key signal according to the audio volume setting is received from the key input unit 122. If a key signal according to the audio volume setting is received from the key input unit 122 as a result of the test, the process proceeds to step 204 to read the audio volume mode stored in the memory unit 121 and display it on the display unit 123. If the data displayed at 123 is described as an example, the data may be classified into "audio volume / audio mode volume during a call". That is, the audio listening volume may be set to a different value when the volume is set in the audio listening mode and during a call. Since the present embodiment is a control flowchart in the audio listening mode, the audio volume is described. However, the radio listening can be similarly stored.

The control unit 111 displays the message as described above in step 204 and proceeds to step 206 to check whether a key signal is received from the key input unit, and when the key signal is received, the received key signal is Check whether the key signal is applied according to the selection of audio volume during the call. If a key signal according to the selection of the audio volume is received during the call as a result of the check, the process proceeds to step 210; otherwise, if the key signal is received according to the selection of the audio mode volume, the process proceeds to step 208. . In step 208, the controller 111 reads and displays the currently set volume value from the memory unit 121 according to the audio mode, and then changes the volume value according to the key signal received from the key input unit 122. After that, the audio mode volume setting process is performed to store the corresponding value.

On the contrary, when proceeding to step 210, the control unit 111 reads the currently stored audio volume value from the memory unit 121 and displays it on the display unit 123 and receives the key received from the key input unit 122. The audio volume value during the call is changed and displayed according to the signal. Through this process, the control unit 111 proceeds to step 214 to check whether the key signal according to the setting is received from the key input unit 122. If the key signal according to the setting is received, the control unit 111 proceeds to step 216, and if not, continues to the step 212. When the setting process is completed, the simultaneous mode state is displayed in the memory unit 121. In this case, the simultaneous mode refers to data depending on whether or not to listen to an audio volume during a call. That is, if audio listening is selected during a call, audio listening bits are set and stored. Otherwise, audio listening bits are reset and stored. Displaying this on the display unit 123 indicates "set" when the audio listening bit is set, and "off" otherwise. The controller 111 toggles and displays the setting and the release in response to the key signal received from the key input unit 122.

In addition, when the controller 111 proceeds to step 218, the controller 111 checks whether a key signal is received from the key input unit 122 according to the selection of the state displayed on the display unit 123. When the key signal according to the selection of the test result is received, the process proceeds to step 220 where the audio volume value selected in steps 212 through 214 and the value selected in steps 216 through 218 are stored in memory. Store in This process is described only as a process according to the setting of the audio volume, but the same process as the setting of the radio volume. In addition, the processes of steps 216 to 220 may be configured by using a routine according to simultaneous mode setting and release in addition to the routine of FIG. 3.

4 is a control flowchart when a call is received when listening to audio / radio according to an embodiment of the present invention. Hereinafter, the control process of the case where a call is received when listening to audio / radio will be described in detail with reference to the block structure of FIG. 2 and the control process of FIG. 3.

The control unit 111 maintains the standby state in step 240. The standby state is the same as the standby state of step 200 of FIG. The controller 111 checks whether a key signal for requesting an audio or radio service is received from the key input unit 122 in step 240. If audio or radio service is required as a result of the inspection, the flow proceeds to step 244. In the following description, the control flowchart of FIG. 4 will be described on the assumption that an audio service is performed. When the controller 111 proceeds to step 244, the controller 111 controls the audio processor 119 to perform an audio service mode. Then, the control unit 111 proceeds to step 246 to check whether the call is received through the receiving unit 115. If the call is received, the procedure proceeds to step 248. If the call is not received, step 244, which is an audio service mode, is continued. The control unit 111 outputs the ringing sound while proceeding from step 246 to step 248. In FIG. 2, a block configuration for outputting ring tone is not shown. In addition, the control unit 111 outputs a ringing tone and determines whether a call path is formed by inputting a call key from the key input unit 122 in step 248. The control unit 111 proceeds to step 250 when the call path is formed, and continues to step 244 when the call path is not formed.

When the controller 111 proceeds to step 250, the controller 111 determines whether the audio listening bit set in the control process of FIG. 3 is set. If the audio listening bit is not set as a result of the test, the process proceeds to step 252, and if the audio listening bit is set, step 258. When the controller 111 proceeds to step 252, the controller 111 controls the audio processor 119 to stop the audio processing. If the listening mode is radio listening, the controller 111 controls the radio receiver 117 to stop receiving and processing radio signals. In step 254, the call mode is performed. The control unit 111 checks whether the ongoing call is terminated when the process proceeds to step 256. When the call is terminated as a result of the test proceeds to the standby state of 240. However, if the call does not end, the call mode of step 254 is continued. In addition, in the present embodiment, when the call is terminated, the process proceeds to the standby state of step 240, but in another way, the radio signal after temporarily storing the data being listened, that is, the volume value and the frequency in the case of the radio listening. The reception and processing operation may be stopped, and when the call is terminated, the process may proceed to step 254 to continue the radio listening or audio listening in progress according to the temporarily stored volume value and frequency data.

On the contrary, if the process proceeds from step 250 to step 258, the controller 111 temporarily stores the volume value of the currently output audio in the memory unit 121. At this time, the volume value of the audio output is the volume value set through step 208 of FIG. The control unit proceeds to step 260 to output a control signal to the audio volume control unit 125 to control to output a preset audio volume value. Here, the preset audio volume value is a value stored in step 220 by setting through steps 210 to 214 of FIG. 3. As a result, the volume output through the speaker SPK is adjusted through the voice volume controller 118 and the audio volume controller 125. In this case, when the volume control is performed during a call, the volume of the audio volume controller 125 continuously maintains a preset value, and only the output value of the voice volume controller 118 changes.

The controller 111 controls to output the volume of step 260 and simultaneously performs a call mode. In step 262, it is checked whether the call is terminated. If the call is terminated as a result of the check proceeds to step (264) and if the call is not terminated performs step (260) and maintains the call mode. When the controller 111 proceeds to step 264, in step 258, the controller 111 reads the volume value stored in the memory 121 and outputs a control signal according to the read volume value to the audio volume controller 125. After restoring to the previously listened volume value, the process proceeds to step (244).

In the above embodiments, only the case where a call is received has been described as an example, but the call may be configured to be performed through the same process.

 As described above, when a call is received or made while a mobile communication terminal is listening to an audio signal or a radio signal, the volume can be lowered to a predetermined level so that the call can be made while listening to music without disturbing the call. have.
