Description

Cell phone having music outputs selectively}

The present invention relates to a mobile phone, and more specifically, to store a plurality of music data assigned a password or a specific symbol for each of the mobile phone, to notify a specific call partner of the mobile phone in advance a password or a specific symbol, The present invention relates to a mobile phone capable of checking a call partner by selectively changing an output music indicating a call of a mobile phone according to a password or a specific code to be input and selectively outputting a music.

Due to the development of mobile communication technology, a portable communication terminal capable of talking to the other party wirelessly while being carried by an individual has been popularized. Representative of these are mobile phones (cellular or cellular phones) and PCS (personal mobile communication terminals). In addition, globally available IMT 2000 is gradually commercialized. In the following description of the present invention, a plurality of communication terminals such as a mobile phone, a mobile phone, a cellular phone, or an IMT2000 referred to above are collectively referred to as a mobile phone.

These mobile phones are using CDMA, TDMA communication. 1 is a configuration example of a mobile phone conventionally used. As shown, a liquid crystal panel 9 for displaying a character is located on the front side, and a plurality of input buttons 5 having a number plate for entering a phone number or a character are provided below. In addition, the antenna is located at the top of the mobile phone is used for transmitting and receiving wireless data.

On the other hand, the speaker 7 is located on the upper side of the liquid crystal panel 9, that is, the part which is in close contact with the ear, and the microphone 3 is located on the lower side of the input button 5, that is, the part adjacent to the mouth, for the call. When the user carries the mobile phone 1 in his hand and speaks with the speaker 7 in his ear, the voice is input through the microphone 3 and transmitted to the call partner. In addition, the voice signal transmitted from the call partner is output through the speaker 7 adjacent to the caller's ear, whereby a call with the other party is possible. The memory element 32a and the interface jack 34a which are not described are the elements according to the present invention, which will be described later.

FIG. 2 is a block diagram illustrating a schematic circuit configuration of the mobile phone of FIG. 1.

As shown, duplexer 10, transmitter 12, receiver 14, key input 16, memory 18, display 20, voice input 22, microphone 24, voice output The unit 26, the speaker 28, and the control unit 11 is included.

The receiver 14 receives and outputs a call signal and a call message of the other party applied through the duplexer 10 from the antenna, and the transmitter 12 connects the call signal and the phone message of the authorized user with the duplexer 10. It transmits through the antenna. When a call signal is input from the other party, the conventional mobile phone outputs music or a ring tone set by the user to notify the user of the call. When the phone detects a call, the user switches to the call mode and then talks.

The key input unit 16 is for inputting a predetermined command, numbers, characters, etc. to the control unit. For input of commands, numbers, characters, etc., a plurality of input buttons 5 to which numeric keys and letters (not shown) as shown in FIG. 1 are assigned are provided.

The memory unit 18 contains a program necessary for control and also stores data input by a user. It also stores character data necessary for the display of characters.

The display unit 20 includes the liquid crystal panel 9 shown in FIG. 1 to display specific characters or information as characters so that a user can recognize them. In addition, the display unit 20 is provided with a sound output circuit (not shown) for outputting a sound signal through a speaker to output a sound signal so that the user can recognize.

The voice input unit 22 receives a voice (analog signal) input by the user during a telephone call from the microphone 24 and transmits it to the controller 11. The transmitted voice signal is modulated into a digital signal and then wirelessly transmitted through an antenna connected to the transmitter 12.

The voice output unit 26 receives the voice of the call partner from the receiving unit 14 connected to the antenna and inputs the voice to the control unit 11. The control unit 11 demodulates the digital voice signal and outputs it through the speaker 28 connected to the voice output unit 26. Therefore, the mobile phone user listens to the other party's voice through the speaker 28 and inputs his or her voice through the microphone 24 to transmit the voice to the other party. The speaker 28 is essentially the same as the speaker 7 of FIG. 1 and the microphone 24 is the same as the microphone 3 of FIG.

However, the above-described conventional mobile phone does not have a means for identifying a telephone caller because the same ring tone or music sound is output even when the other party makes a phone call. In other words, in order to check the caller, if the call music or the call signal is output, the person who does not want to answer the call is only able to confirm the caller after listening to the other party's voice while holding the phone and switching to the call mode. There was a discomfort that even if a call came from.

The present invention has been made to solve the above problems, an object of the present invention is to provide a mobile phone that can select the mobile phone call music output by the call partner to confirm the identity of the call partner.

Another object of the present invention is to provide a mobile phone capable of music selection output that can increase the added value of the mobile phone by providing more various and convenient functions in the conventional mobile phone.

Cell phone capable of music selection output of the present invention for achieving the above object is a music selection control unit for receiving a music selection signal input by the other party's telephone call from the control unit of the mobile phone and outputs a control signal for outputting specific music; A music data storage unit for outputting music data corresponding to the corresponding music by a control signal output from the music selection controller, an input interface unit for inputting music data from the outside, and music data output from the music data storage unit; It includes a D / A converter for modulating the analog signal to the voice output unit of the mobile phone.

Hereinafter, a mobile phone capable of selecting music according to the present invention will be described in detail with reference to the accompanying drawings.

First, referring to Figure 1 again, the appearance of the mobile phone according to the present invention will be described.

According to the present invention, the insertion hole 32b is formed on the side of the mobile phone 1, and the interface jack 34a is provided adjacent thereto. The insertion hole 32b fixes the memory element 32a so as not to move and has a structure in which the memory element 32a can be separated from the insertion hole 32b when necessary.

The memory element 32a is a storage element for storing a plurality of music data selected by the present invention. By selecting the memory element 32a as a separate type, the capacity can be easily increased to store more music data, and there is an advantage in that the music data can be easily updated.

The music data is stored in the memory device 32a in two ways. The first method is to receive the music data from the base station of the mobile phone station and store it in the memory device 32a as in the prior art. The second method is to receive and store the music data to the memory device 32a using an external device. . The external device for transmitting music data may be, for example, a device such as a computer, a PDA, or the like that can process digital audio files, or a vending machine type device.

The vending machine is configured to be used by connecting to the connector of the vending machine or the like, or by connecting to the interface jack 34a after removing the memory device 32a mounted on the cellular phone. The interface jack 34a is preferably configured using a connector that satisfies a data transmission standard mounted on a computer, a PDA, or the like.

After the user activates the music data transmission and storage function by using a specific function key of the mobile phone, the user receives the music data he / she wants from the base station or an external device using the music data storage function displayed on the liquid crystal panel 9 and stores it. do.

It is apparent that the position of the insertion hole 32b and the interface jack 34a can be changed depending on the structure of the cellular phone.

3 is an embodiment of a block circuit diagram of the mobile phone as described above.

As shown, it can be seen that the music selection control unit 30, the music data storage unit 32, the input interface unit 34, and the D / A conversion unit 36 are further installed in the components of the conventional mobile phone. Can be.

The music selection controller 30 controls to output specific music using the control signal data input from the controller 11. The music selection controller 30 may be configured using a one chip microcomputer. The control signal data input from the control section 11 to the music selection control section 30 can be configured in two ways, which will be described later. Also, in the present invention, the music selection function may be turned off so that only one music signal or a ring tone is output for the call signal as in the related art.

The music selection control unit 30 receives a signal from the control unit 11 including a command signal (password or specific symbol) to play a specific music among a plurality of music set by the user. The music selection controller 30 recognizes the specific music using the input signal and then outputs a control signal for reproducing the set music to the music data storage 32.

The music data storage unit 32 extracts the corresponding music data by the control signal output from the music selection controller 30, and outputs the extracted music data to the D / A converter 36. The D / A converter 36 converts the digital music data into an analog signal and outputs the converted music data. The music data storage unit 32 includes a memory element 32a (see Fig. 1) for storing music data with a function for extracting data. The memory device 32a is configured by using a nonvolatile memory device such as a flash memory to read / write data.

It is also possible to remove one of the insertion port 32b and the interface jack 34a and configure it as a single function. In other words, the insertion hole 32b is removed and the memory device 32a is inseparably fixed, and the music data is transmitted and stored using the interface jack 34a, or the interface jack 34a is removed and the memory device ( It is also possible to comprise 32a) detachably.

The analog music signal output from the D / A converter 36 is amplified by a signal of a suitable size in the voice output unit 26 of the cellular phone and output to the speaker 28. Therefore, the mobile phone user can listen to music output through the speaker 28. At this time, since the music output is music assigned to a specific password or a specific symbol, the user can determine who is calling by listening to the music. Of course, you have to tell a specific person a specific password or symbol in advance.

The input interface unit 34 includes a jack 34a for using an interface for receiving music data to the memory device 32a of the music data storage unit 32 as described above. Since music data is usually in the form of digital audio, it is preferable to use a communication standard capable of transmitting digital data, in particular, an interface capable of receiving music data from a computer or a PDA.

The operating state of the cellular phone of the present invention having the above configuration will be described using the flowchart of FIG.

The call signal is input to the mobile phone in the call waiting state. When the call signal is input, the control unit 11 of the cellular phone checks whether it is in the password input mode or the normal call state. At this time, the control unit 11 first determines whether the reception state of the cellular phone is a single music output mode (a conventional cellular phone signal reception mode). This may be performed by further adding a function to the control unit 11. In the single music output mode, it ignores the input of a password or a specific symbol and outputs music for unconditional calling.

In the case of not the single music output mode, the control signal data input from the control unit 11 to the music selection control unit 30 can be implemented in two ways. The first is a method of transmitting the control data for outputting specific music in the mobile phone call signal transmitted from the base station (in the present invention, the password input mode is set), the second is the mobile phone of the specific function is not activated state After switching to call mode, it detects password or specific input status and selects music.

The former has the disadvantages to be supported by the mobile phone company, but can be a way to benefit the user. The latter has the disadvantage of being charged because it operates in the normal call mode when calling the mobile phone, but it does not have to be supported by the mobile phone company.

If it is determined that the password is in the password input mode, the controller 11 extracts the password included in the transmitted signal and outputs the password to the music selection controller 30. At this time, the music by the call from the base station is not output as in the prior art.

The music selection control unit 30 determines the music data set in the password using the input password. When the selected music data is determined, the control signal is extracted to extract the corresponding signal from the music data storage unit 32.

The music data storage unit 32 extracts the selected music data and transmits it to the D / A converter 36. The transmitted music data is input to the voice output unit 26 after digital-to-analog conversion by the D / A converter 36, amplified, and then output through the speaker 28. When the music is output, the user listens to the music and checks the other party. After that, if you want to talk, switch to call mode and talk to the other party. If you don't want to talk, you can stop the call by not putting your phone in talk mode.

If it is determined by the control unit 11 that the password input mode is not determined, the control unit 11 switches to the call mode. At this time, the signal or voice input from the counterpart is activated so that the reception unit is normally output, and the operation of the voice input unit 22 is stopped. Therefore, the voice or sound of the user of the mobile phone is not transmitted to the other party.

In this standby state, the music selection controller 30 detects a dial tone (password or specific symbol input) input from the counterpart through the controller 11. If a dial tone is detected from the other party, it is converted into a number or a specific symbol and then output to the music data storage unit 32.

The music data storage unit 32 extracts the selected music data and transmits it to the D / A converter 36. The transmitted music data is input to the voice output unit 26 after digital-to-analog conversion by the D / A converter 36, amplified, and then output through the speaker 28. When the music is output, the user listens to the music and checks the other party. After that, if you want to talk, switch to call mode and talk to the other party. If you don't want to talk, you can stop the call by not putting your phone in talk mode.

The mobile phone function as described above may be selected and applied in a function switching mode. However, if you do not want the password input mode, by selecting the normal mobile phone operation mode as in the prior art to output the music or ring signal in accordance with the call signal.

Although the above description of the present invention has given an example of a mobile phone (cellular or cellular phone), it is obvious that the same can be applied to other wireless communication terminals such as IMT2000, PCS phone and the like. In other words, the present invention can be applied to any communication device capable of wireless transmission and reception and having a voice input and voice output function.

According to the present invention as described above by changing the output music indicating the call call of the mobile phone to the password or contract signal inputted by the telephone call partner of the mobile phone has the advantage that the call partner can be identified and the call selectively.

In addition, by further diversifying the functions of the conventional mobile phone, there is an advantage in that it is possible to expand convenience of use and choice for consumers.

Although the invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that modifications and variations can be made within the spirit and scope of the invention, and such variations or modifications will belong to the appended claims. .
