BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for adjusting a dial tone in a mobile communication terminal, and more particularly, to an apparatus and method for adjusting a dial tone in a mobile communication terminal.

In general, a user sets and uses a handset of a mobile communication terminal to be suitable for them. In this case, there is a disadvantage in that the user cannot quickly respond to a changing surrounding situation.

For example, if you normally set the handset to the size of the call in a quiet place such as an office, it is okay to make a call with the set size of the handset in the quiet place, but in the noisy place Since the call cannot be made with a set-tone handset, you need to adjust the handset a little louder.

In the conventional mobile communication terminal as shown in FIG. 1, the apparatus for adjusting a dial tone includes a key input unit 11, a dial tone control unit 12, a call volume control signal generator 13, and an MSM ( 14), a memory unit 15, and a transceiver unit 16 are included.

The key input unit 11 detects an input of a dial tone control button or a call volume control button formed on a keypad of a mobile communication terminal, and then inputs a call tone control button or a call volume control button input by a user to the MSM ( 14).

The handset adjusting unit 12 controls the voice output device unit (not shown in the drawing for convenience of description) of the mobile communication terminal according to the control of the MSM 14 to adjust the size of the handset so that the adjusted Outputs a loud sign language.

The talk volume control signal generator 13 generates a talk volume control signal under the control of the MSM 14 and applies it to the transceiver 16.

The MSM 14 controls the overall operation of the mobile communication terminal. The MSM 14 is notified of a handset control button input through the key input unit 11 and according to the received handset control button. Control the operation of (12), and receives the call volume control button input through the key input unit 11 to control the operation of the call volume control signal generator 13 according to the received call volume control button.

The memory unit 15 stores a program and data necessary for the control operation of the MSM 14.

The transmitter / receiver 16 transmits a talk volume control signal applied from the talk volume control signal generator 13 under an control of the MSM 14 through an antenna. Not sent).

In the conventional mobile communication terminal having the above-described configuration, there are two methods of adjusting a dial tone, a method of using a dial tone control button and a method of using a call volume control button.

First, in the case of using the handset control button, when the user presses the handset control button to adjust the handset so that the other party's voice is heard well during a call, the MSM 14 recognizes this and the handset control unit recognizes it. By controlling the operation of (12), the corresponding sound control unit 12 controls the voice output device unit of the mobile communication terminal under the control of the corresponding MSM 14 to adjust the size of the sound by the corresponding adjusted size It will be output as a sign language.

For example, if the other party's voice is small, you can press the voice up button to increase the handset, and if the other party's voice is loud, press the lower button to adjust the handset sound. It can be made small.

However, in the first case, even if the user adjusts the handset through the handset control button, there is a limit in increasing the size of the handset if the voice of the other party itself or the output of the handset is small. There are disadvantages.

Secondly, in the method of using the call volume control button, the user cannot hear the sound of the sound heard through the speaker of his mobile communication terminal (i.e., the receiving terminal) during a call, so that the voice of the other party can be heard well. When the talk volume control button is pressed in order to adjust, the MSM 14 recognizes this and controls the operation of the talk volume control signal generator 13, so that the talk volume control signal generator 13 corresponds to the corresponding MSM 14. ) Generates a call volume control signal and transmits it to the mobile communication terminal (ie, the transmitting terminal) of the other party via the antenna via the transceiver 16.

Accordingly, the transmitting terminal adjusts the calling volume according to the calling volume control signal received from the receiving terminal, and then transmits a voice signal having the adjusted calling volume to the receiving terminal. The terminal outputs a volume-adjusted voice signal received from the transmitting terminal as a sign language.

For example, when the other party's voice is small, the voice volume raising control signal can be transmitted to the transmitting terminal by pressing the voice raising button among the volume control buttons to increase the handset volume of the receiving terminal. On the contrary, when the other party's voice is loud, by pressing the sound down button among the talk volume control buttons, the talk volume reduction control signal is transmitted to the sender terminal, thereby reducing the talk volume of the receiver terminal.

However, in the second case, instead of automatically adjusting the volume of the call, the user transmits a signal for controlling the output of the mobile communication terminal of the other party rather than the user's own mobile communication terminal to send the signal to the mobile communication terminal of the other party. Because of the need to control, there was a disadvantage that problems may occur in the call quality.

SUMMARY OF THE INVENTION The present invention has been made in an effort to provide an apparatus and a method for adjusting a phonetic tone in a mobile communication terminal to automatically adjust the size of a phonetic tone in a mobile communication terminal.

Preferably, the process of outputting a sign language raises and outputs the volume of a sign sound when the analyzed volume is greater than the read reference volume, and when the analyzed volume is smaller than the read reference volume. It is characterized by outputting the size of the lowering.

Further preferably, the process of outputting a sign language includes: presetting a sign volume adjustment width corresponding to a difference value between the analyzed volume and the read reference volume; Obtaining a difference value between the analyzed volume and the read reference volume upon automatically adjusting the loudness of the dialect; And adjusting the size of the sign sound by the corresponding adjustment width by reading the adjustment width corresponding to the obtained difference value.

Alternatively, the sign language output process may be configured to continuously compare the analyzed volume with the read reference volume to adjust the volume of the sign language in a stepwise manner.

The present invention adds a function to analyze the voice size of the receiver in the mobile communication terminal to determine whether the corresponding voice size is above a certain amount or less, and to adjust the size of the sign language accordingly. In other words, according to the present invention, after the user's usual voice size is preset in the mobile communication terminal, the voice of the receiver is received during the call, and the voice size of the corresponding receiver is analyzed and compared with the preset voice size. If the loudness is larger than the preset voice volume, it is determined that the user is in a noisy place and automatically adjusts the loudness of the handset. If the voice size of the receiver is smaller than the preset loudness, the user is said to be quiet. It judges and adjusts to lower the volume of the sign language automatically. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the mobile communication terminal according to an embodiment of the present invention, as shown in FIG. 2, the apparatus for adjusting a sign tone includes a key input unit 21, a volume measuring unit 22, a sign language adjusting unit 23, and an MSM ( 24, a memory unit 25, and a transceiver 26.

The key input unit 21 detects an input of a voice recording button for recording a reference voice of a user or a mode setting button for setting an automatic sound control mode for automatically adjusting the size of a handset sound according to a user's surroundings. After that, the MSM 24 is notified of the voice recording button or the mode setting button input by the user.

The volume measuring unit 22 analyzes the wavelength of the user's voice input through the microphone provided in the mobile communication terminal under the control of the MSM 24, and analyzes the corresponding wavelength and the magnitude thereof in the MSM 24. I inform you.

The handset adjusting unit 23 controls a voice output device unit (not shown in the drawing for convenience of description) provided under the control of the MSM 24 to adjust the size of the handset. Outputs the sound with the adjusted scale.

The MSM 24 controls the overall operation of the mobile communication terminal. The MSM 24 receives a voice recording button input through the key input unit 21 and is provided with the display device unit (for convenience of description). (Not shown in the drawing) or by controlling the operation of the voice output device unit to notify the user of the voice input message and at the same time to control the operation of the volume measuring unit 22, the mode input button input through the key input unit 21 Reads from the memory unit 25 and executes a control program for executing the automatic dial tone adjustment mode. After confirming that the mobile communication terminal is currently in communication with the other party, it is determined whether the automatic dial tone adjustment mode is set. Check and control the operation of the volume measuring unit 22, and the wavelength and the size analyzed by the volume measuring unit 22 Reads the reference volume stored in the memory unit 25 and compares whether the volume analyzed by the volume measuring unit 22 is larger or smaller than the reference volume read from the memory unit 25. As a result, the operation of the sign language control unit 23 is controlled.

The memory unit 25 stores a program and data necessary for the control operation of the MSM 24. In particular, the memory unit 25 corresponds to a user's surrounding situation when the mobile communication terminal is used (that is, during a call). It stores the reference volume that can automatically adjust the volume of the sign language according to the volume of the voice, and stores a control program for performing the automatic control mode of the sign language. At this time, the reference volume is set by the analysis operation of the volume measuring unit 22.

The transceiver 26 is connected to a mobile communication terminal (not shown in the drawings for convenience of explanation) through a base station (not shown in the drawings for convenience of description) through an antenna under the control of the MSM 24. Perform wireless communication.

Referring to the flowchart of FIG. 3, a method for adjusting a sign language in a mobile communication terminal according to an embodiment of the present invention is as follows.

First, in order to set a criterion for automatically adjusting the size of a phonetic sound to the extent that the user hears the other party's voice well during a call, the voice recording button of the key input unit 21 for inputting a voice of the corresponding criterion is used. When pressed, the MSM 24 recognizes this (step S31), and then controls the operation of the voice output device or the display device provided in the mobile communication terminal to 'put the user's voice in the usual voice size'. Notifies the user of the message (step S32).

At this time, the reason for inputting the user's voice is that when the user's voice is not heard well when the mobile communication terminal is in use (that is, during a call), the user is asked loudly or the user is noisy. It is usually asked loudly, whereas the user tends to be quiet when the situation around the user needs to speak quietly. This is because you can set an adjustable standard.

For example, if a user cannot hear the other party's voice in a noisy place such as a performance hall, the user may determine that his or her voice is not well transmitted by the surrounding noise, and call the user 'Hello' loudly. In a quiet place, such as a conference room, the user makes a small call to 'hello', so that the volume is automatically adjusted according to the volume of the user's voice. By making the chords smaller, you will not only be able to hear the other person better, but also avoid harming those around you.

Accordingly, when the user inputs his or her own voice through a microphone provided in the mobile communication terminal, the volume measuring unit 22 receives the user's voice through the microphone under the control of the MSM 14 (step S33) After measuring the volume of the input user, that is, after analyzing the wavelength for the user's voice (step S34). The analyzed wavelength and its magnitude are set as the reference volume and stored in the memory unit 25 (step S35).

In addition, when the user presses the mode setting button of the key input unit 21 for setting the auto dial tone control mode so that the user can automatically adjust the volume of the dial tone according to the surrounding situation, the MSM 24 After recognizing this in step S36, a control program for performing the automatic sound control mode stored in the memory unit 25 is read, and the read control program is executed to perform the read control program according to the control program. The automatic adjustment operation is performed (step S37).

Accordingly, when the user makes a call with the other party, the MSM 24 detects this (step S38) and checks whether the automatic dial tone adjustment mode is set (step S39). If it is not set to the automatic dial tone control mode in S39) it is made to perform the operation of manually adjusting the dial tone in the same manner as in the prior art (step S40).

On the other hand, in the case where it is set to the automatic dial tone control mode in step 39 (S39), the MSM 24 controls the operation of the volume measuring unit 22 to send the user's own voice through the microphone. The volume measurement unit 22 receives the user's voice through the microphone under the control of the MSM 14 (step S41), and then analyzes the wavelength of the input user's voice (step S41). Step S42). The MSM 24 is informed of the analyzed wavelength and its magnitude.

Then, the MSM 24 receives the wavelength analyzed by the volume measuring unit 22 and the magnitude thereof, and reads the reference volume set in the memory unit 25 (that is, the reference wavelength and its magnitude). (Step S43), the wavelength notified from the volume measuring section 22 and its magnitude are compared with the reference volume read out from the memory section 25. FIG.

In other words, the MSM 24 compares the wavelength reported from the volume measuring section 22 and whether the magnitude is larger or smaller than the reference volume read out from the memory section 25 (step S44). According to the result, a sound signal control signal is generated and applied to the sound signal controller 23 to control the operation of the sound signal controller 23.

If, in the 44th step (S44), the wavelength reported from the volume measuring unit 22 and its magnitude are larger than the reference volume read out from the memory unit 25, the MSM 24 receives a sign sound. It is determined that the sound is difficult to be heard, and the sound raising control signal of the sound control signal is generated and applied to the sound control unit 23, so that the sound control unit 23 controls the sound raising of the MSM 24. The voice output device is controlled according to the signal to increase and adjust the size of the sign language so as to be output as a louder sign language (step S45).

At this time, the adjustment of the loudness of the sign language may be performed in advance by adjusting the amplitude of the sign language volume corresponding to the difference value between the wavelength and the magnitude notified from the volume measuring section 22 and the reference volume read out from the memory section 25. After the setting in the memory unit 25, the actual value is adjusted to obtain a difference value between the wavelength and the magnitude notified from the volume measuring unit 22 and the reference volume read out from the memory unit 25. Read the corresponding scaling width and raise the melody by that scaling width.

Alternatively, the wavelength and the magnitude analyzed by the volume measuring unit 22 are continuously informed and continuously compared with the reference volume read from the memory unit 25 to increase the loudness of the sign language step by step. Adjust the loudness of the sign language.

On the other hand, when the wavelength and the size of the signal notified from the volume measuring unit 22 are smaller than the reference volume read out from the memory unit 25 in the 44th step S44, the MSM 24 receives a sign sound. It is determined that the loudness control signal of the sound control signal is generated and applied to the sound control unit 23, so that the sound control unit 23 according to the sound control signal of the MSM (24) The voice output device is controlled to adjust the size of the sign language to be lowered to output the smaller sized sign sound (step S46). At this time, since the fall control of the sign language is similar to the rise control of the sign language, the description thereof is omitted.

As described above, in the mobile communication terminal according to an embodiment of the present invention, the method for adjusting a phone call tone is compared with / analyzes a wavelength already stored when the caller speaks with a louder or smaller sound than usual. And to adjust the output of the sign language to the size, that is, the caller himself to adjust the volume so that you can hear the other party's voice equal to the volume of the talking to facilitate the communication.

For example, if the other party's voice is heard in a small way, the user himself / herself makes a loud call and automatically adjusts the handset to a corresponding size so that the other party's voice can be heard well, while the quiet place etc. For this reason, when a user makes a call with a small sound, the handset sound is automatically adjusted to a size corresponding to the voice of the user so that the other party's voice is also heard small.

And, in the mobile communication terminal according to an embodiment of the present invention, a method for adjusting a dial tone enables a user to selectively or automatically control a dial tone, even when the operation is performed in the dial tone automatic adjustment mode. When the user inputs a call tone control button or a call volume control button formed on the keypad of the mobile communication terminal, the call volume is determined by an interrupt so that the call volume can be manually adjusted.

As described above, the mobile communication terminal measures the volume of the caller and automatically adjusts the size of the handset sound according to the measured volume, so that the voice of the other party can be heard according to the surrounding situation of the user. The tone can be adjusted automatically.
