The present invention relates to a method for automatically controlling a hydration volume by ambient noise in a wireless terminal.

Normally, the telephone tone sounds are generated according to a preset volume when a telephone call is made. However, the generation of this harmonic tone is not able to actively cope with the surrounding environment, thus causing many difficulties.

For example, when the volume of the sign language is set to a large value, when a call is made in a quiet environment, the call sound may be heard and the call content may be known to the other person. Also, when the volume was too high, the auditory cells were overstimulated. In addition, when the volume of the sign language is set to be small, the user can not grasp the contents of a call when a call is made in an area with a lot of noises such as a subway. Therefore, the user often makes a phone call while making a call.

In addition, the above-described situation causes the same problem even when the received voice is received small or received largely despite the adjustment of the hydration volume.

For example, if the received voice is small due to the problem of the system or the terminal of the communication partner, the call contents can not be grasped. Also, when the received voice is received largely, the contents of the call are notified to the other person.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method for automatically generating a sound by measuring the volume of a received sound.

And will be apparent to those skilled in the art. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 is a block diagram of a wireless terminal according to an embodiment of the present invention.

The controller 120 of the wireless terminal controls the overall operation of the wireless terminal. The key input unit 110 includes a plurality of numeric keys and function keys for performing various functions, and outputs the key data to the control unit 120 through an external operation. The memory 100 includes a ROM for storing an operation program and an EEPROM and a RAM for electrically programming. The volume measuring unit 130 measures the ambient noise input through the microphone 160. The volume measuring unit 130 measures the noise through the converted signal when the microphone 160 converts the ambient noise into an electrical signal and outputs the electrical signal. Also, the voice signal input through the RF unit 180 is measured to measure the volume of the received voice. The display unit 140 is a display device such as a liquid crystal display (LCD). The display unit 140 displays the status of the wireless terminal and the progress of the program under the control of the controller 120. [ The microphone 160 converts the voice signal into an electrical signal and transmits the voice signal to the amplifying unit 190. The speaker 170 outputs the voice output through the amplifying unit 190. The RF unit 180 is controlled by the controller 120 and transmits a signal output from the amplifying unit 190 to the base station. The RF unit 180 converts the radio signal received through the antenna into a desired signal and outputs the signal. The amplifying unit 190 modulates the voice signal input from the microphone 160 into voice data, demodulates the voice data input from the RF unit 180 into voice signals, and outputs voice signals through a speaker. That is, the amplification unit 190 amplifies a signal input / output through the speaker 170 and the microphone 160, or amplifies a voice signal and various transmission / reception data output through the RF unit 180. The hydration volume control unit 150 controls the volume of the voice output to the speaker 170 under the control of the control unit 120.

2 is a control flowchart for automatically adjusting the hydration volume according to an embodiment of the present invention.

In step 200, the control unit 120 measures the ambient noise inputted through the microphone 160 through the volume measuring unit 130. The measured noise can be expressed as shown in Table 1 below.

noise Noise [dB] Prize More than 80 medium 40 to 80 Ha 40 or less

The noise may be measured for a predetermined period of time or may be measured for a predetermined period of time. For example, you can measure for three seconds or three times for two seconds at one second. In step 210, the control unit 120 determines whether the call path is connected. If the call connection is established, the process proceeds to step 220; otherwise, the call connection is continuously waited for. In step 220, the controller 120 checks whether the noise is "up" according to the noise measured in step 210. [ For example, as shown in Table 1, if the measured noise is 80 decibels or more, the process proceeds to step 230. If the measured noise is 80 decibels or less, the process proceeds to step 240. In step 230, the control unit 120 outputs the hydration sound volume as "up" by the speaker 170 through the hydration sound volume control unit 150. [ In step 240, the controller 120 checks whether the volume of the noise is about 40 to 80 decibels, for example. If the noise is 40 decibels or more, the process proceeds to step 250. If the noise is less than 40 decibels, the process proceeds to step 260. [ In step 250, the control unit 120 outputs the hydration sound volume as "medium" to the speaker 170 through the hydration sound volume control unit 150. [ In step 260, the control unit 120 outputs the reception volume to "lower " by the speaker 170 through the reception volume adjuster 150. [ In step 270, the controller 120 checks whether the call is terminated. If the call is disconnected, the program is terminated. Otherwise, the process proceeds to step 280. In step 280, the control unit delays a predetermined period of time, and then returns to step 210. That is, while the call is being made, the reception sound volume continuously received is measured to adjust the reception sound volume and output.

3 is a control flowchart for automatically adjusting the hydration volume according to another embodiment of the present invention. The flow chart shown in FIG. 3 is a flowchart for adjusting the hydration volume by measuring the received hydration volume. First, in step 300, the control unit 120 checks whether a call connection is established. If the call is connected, the process proceeds to step 310, otherwise, the call is continuously checked. In step 310, the control unit 120 measures the volume of the voice received through the RF unit 180 through the volume measuring unit 130. For example, as shown in Table 2 below.

Hydration volume Volume of received voice [dB] Ha More than 80 medium 40 to 80 Prize 40 or less

The volume measurement of the received voice may be measured for a predetermined time or a predetermined number of times for a predetermined time. For example, you can measure for three seconds or three times for two seconds at one second. In step 320, the controller 120 checks whether the volume of the received signal is "up" according to the volume of the received sound measured in step 310. [ That is, for example, as shown in Table 1, if the measured noise is 80 decibels or more, the process proceeds to step 330. If the measured noise is 80 decibels or less, the process proceeds to step 340. [ In step 330, the control unit 120 adjusts the volume through the hydration volume control unit 150 and outputs the generated sound to the speaker 170 by "lower ". In step 340, the controller 120 checks whether the measured noise is about 40 to 80 decibels, for example. If the noise is 40 dB or more, the process proceeds to step 350. If the noise is less than 40 dB, the process proceeds to step 360. In step 350, the control unit 120 adjusts the volume through the hydration volume adjuster 150 and outputs the hydration sound as "medium" In step 360, the control unit 120 adjusts the volume through the hydration volume adjuster 150 and outputs the hydration sound as "up" by the speaker 170. In step 370, the control unit 120 checks whether the call path is disconnected. If the call is terminated, the program is terminated. Otherwise, the procedure proceeds to step 380. In step 380, the controller 120 delays a predetermined period of time and then returns to step 310.

4 is a control flowchart for automatically adjusting the hydration volume according to another embodiment of the present invention. In FIG. 4, both the ambient noise and the received hydration loudness are measured, and the hydration loudness is controlled by taking into account two factors.

First, in step 400, the control unit 120 measures the ambient noise inputted through the microphone 160 through the volume measuring unit 130. FIG. In step 410, the control unit 120 checks whether a call connection is established. If the call is connected, proceed to step 420. Otherwise, it is checked whether the call is continuously connected. In operation 420, the control unit 120 measures the volume of the received sound volume received through the RF unit 180 through the volume measuring unit 130. The noise measurement in step 400 and the volume measurement of the received voice in step 420 may be performed for a predetermined time or for a predetermined time. For example, you can measure for three seconds or three times for two seconds at one second. In step 430, the control unit 120 checks whether the hydration sound volume value is in the range shown in Table 3, for example.

 Receive signal volume Noise [dB] 10 20 30 40 50 60 70 80 90 120 . . . 10 medium medium Ha Ha Ha Ha Ha Ha Ha Ha . . . 20 medium medium medium Ha Ha Ha Ha Ha Ha Ha . . . 30 medium medium medium medium Ha Ha Ha Ha Ha Ha . . . 40 Prize medium medium medium medium Ha Ha Ha Ha Ha . . . 50 Prize Prize medium medium medium medium Ha Ha Ha Ha . . . 60 Prize Prize Prize medium medium medium medium Ha Ha Ha . . . 70 Prize Prize Prize Prize medium medium medium medium Ha Ha . . . 80 Prize Prize Prize Prize Prize medium medium medium medium Ha . . . 90 Prize Prize Prize Prize Prize Prize medium medium medium medium . . . 120 Prize Prize Prize Prize Prize Prize Prize medium medium medium . . .  . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

As shown in Table 3, it can be seen that the hydration loudness value to be output according to the noise is proportionally increased and inversely proportional to the volume of the received voice. In step 440, the control unit 120 adjusts the hydration sound level to "up" In step 450, the control unit 120 checks whether the hydration volume value is in operation. If the hydration loudness value is in the middle, the process proceeds to step 460; otherwise, the process proceeds to step 470. In step 460, the control unit 120 adjusts the hydration volume to "medium" In step 470, the control unit 120 adjusts the hydration volume to "low" through the hydration volume controller 150 and outputs the adjusted volume to the speaker 170. In step 480, the controller 120 checks whether the call is terminated. If the call is disconnected, the operation for adjusting the hydration volume is terminated. Otherwise, the procedure proceeds to step 490. In step 490, the controller 120 delays a predetermined period of time, and then proceeds to step 410.

The embodiment of Figures 2, 3 and 4 divides the noise into three stages, but this classification can be easily divided into arbitrary steps. In addition, although the wireless terminal is taken as an example in the present embodiment, it can be applied to a communication terminal such as a mobile phone and a general telephone.
