The present invention relates to a receiving terminal, and more particularly, to a receiving terminal including a tone changing device capable of changing the tone received according to a condition preferred by each of a plurality of users during a call.

Voice change technique is to change the pitch of the voice so that the contents of the voice can be recognized but the voice cannot be identified. This technique is mainly used to protect the identity of the speaker in TV or radio broadcasting. to be. This voice modulation technique can be broadly described as echo control, vibration processing, and robot voice processing for the original sound as well as pitch control for the voice signal.

In general, a communication system includes a terminal for voice or data exchange. The communication system shown in FIG. 1 includes a control unit 14 for controlling overall operations of a terminal, a key input unit 10 including a plurality of dialing digit keys, a menu key, and a voice memory for storing a plurality of voice messages ( 16 and a voice processing unit 26 for analog processing a voice message read out from the voice memory 16 under the control of the control unit 14 and transmitting the same through a speaker, and inputs a signal generated by the control unit 14 to digital wireless. Transmitter 20 modulates and delivers to duplexer 22, duplexer 22 for transmitting a radio signal received from transmitter 20 through an antenna, and receiver 18 for receiving a signal received through an antenna. It is composed.

While using the terminal for voice exchange of such a communication system, there is a problem of feeling unpleasant in listening to the loudspeaker or loud sound (an angry voice) transmitted from the transmitter 20 at the receiver 18. In addition, the receiver having a lower hearing characteristics than those of the general public or those with hearing problems have problems during a call that it is difficult to accurately hear the other party's voice on the telephone.

Accordingly, a technical problem to be achieved by the present invention relates to a receiving terminal including a tone changing device capable of changing a tone received according to a condition preferred by each of a plurality of users during a call.

In order to achieve the above technical problem, a receiving terminal including a tone changing device according to the present invention is used tone setting having a plurality of tone mode is set according to the condition of preference of each of a plurality of users using the receiving terminal Wealth; A tone selection unit for selecting one of a plurality of tone modes preset before or during reception by the use tone setting unit; And a tone conversion unit for converting a tone of the caller through the receiver telephone line according to the tone mode selected by the tone selection unit.

The tone setting unit may include: a memory in which a tone condition preferred by each of a plurality of users is stored; And a keypad on which the tone condition key corresponding to the tone condition stored in the memory and one or more tone change function keys are formed.

The tone change function key may include at least one of a clear sound mode, a solo sound mode, a gradually changing sound mode, and a gradually decreasing sound mode.

The tone selector has a CPU having a tone conversion algorithm for converting a caller's voice into a tone selected by the user through the keypad.

The tone converting unit may include a DSP for converting a tone of a caller by a user of the receiving terminal according to an algorithm selected through the keypad.

Other technical problems and advantages of the present invention in addition to the above technical problem will be apparent from the description of the preferred embodiment of the present invention with reference to the accompanying drawings.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 2 and 3.

2 is a block diagram illustrating a receiving terminal including a tone changing device according to the present invention.

As shown in FIG. 2, a receiving terminal including a tone changing device includes an A / D converter 122 for digitizing voices input from a talker, and a receiver terminal for receiving voices input from the A / D converter 122. A tone setting unit 130 and a tone setting unit 130 including a memory 133 storing a preferred condition of each of a plurality of users to use, and a keypad 132 having a tone condition corresponding to the memory 133. DSP 144 for converting the tone selected from the voice according to the control of the CPU 142 and the CPU 142 for controlling the DSP 144 so that the caller's voice is converted to the tone selected by the user via the keypad 132; A tone converter, a D / A converter for analogizing the signal changed by the DSP 144, and a hybrid circuit unit 126 for transmitting the voice analogized by the D / A converter 124 through a telephone line. .

The A / D converter 122 receives the analog tone of the user input from the talker, digitizes it, and transmits the digitized tone to the DSP 144.

The tone setting unit 130 includes a memory 133 in which a condition preferred by each of a plurality of users using a receiving terminal is stored, and a keypad 132 having a condition corresponding to the memory 133.

The tone setting unit 130 shown in FIG. 3 includes a plurality of dialing digit keys, a menu key, a transmission key, and the like on one side of the terminal, and a shortcut key for each tone condition for converting voice and one or more tone changing functions on the other side. It consists of a keyword 132 containing a key.

Here, the tone setting key for each tone condition of the tone setting unit 130 is a mode for converting into a tone that makes a pleasant sound only for a father who is sensitive to a loud sound or an environment when taking an example of using a single terminal by multiple users. If you have a hearing problem, such as grandfather, the mode to reduce the sound of the noise, the mode to convert to the voice of adults for the safety of children who keep their homes alone, and normal when received It is preset by the mode to convert.

In addition, the tone change function key includes at least one of a clear sound, a 'sole' sound mode, a sound that is gradually louder, and a sound that is gradually smaller.

Through the tone setting unit 130, the receiver may use a shortcut key for each tone condition corresponding to the tone of the tone setting unit 130 and at least one tone change key before or during reception.

The tone selector 134 is a DSP 144 for converting a tone selected from the tone setter 130 according to the control of the CPU 142 and a caller's voice is converted into a tone selected by the user through the keypad 132. The CPU 142 controls the DSP 144. The CPU 142 includes an algorithm capable of generating various tones to manipulate the DSP 144 according to the algorithm. That is, the CPU 142 controls the digital signal processing operation of the DSP 144 to generate the tone of the selected mode.

The tone converting unit 140 includes a DSP 144 for converting a tone of the caller of the transmitting terminal by the user of the receiving terminal according to an algorithm selected through the keypad 132.

Here, the DSP 144 operates the digitized voice of the user under the control of the CPU 142. In other words, the voice operated by the DSP 144 is input to the receiver as the voice by mode selection of the receiver.

The D / A converter 124 analogizes the digitized timbre again. In this case, the voice may be converted differently from the voice input to the talker.

The hybrid circuit unit 126 transmits the voice output from the D / A converter 124 to the telephone line.

Therefore, the receiving terminal according to the present invention is able to adapt to the various needs of the user by changing the tone according to the preference condition of each of the plurality of users.

As described above, the receiving terminal including the tone changing device according to the present invention can increase the call quality by changing the tone according to the preference condition of each of the plurality of users.

In other words, the receiver who has a loud or violent sound (an angry voice) or hearing characteristics that are less than the general public or who has a hearing problem while using a terminal for voice exchange of a communication system selects a desired mode and feels like a call. You can do it nicely.

From the above description, those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the description of the specification but should be defined by the claims.
