Cell phone {Cellular phone}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone capable of producing a desired melody sound in response to an incoming call, and more particularly, to a mobile phone that facilitates the selection and viewing of an incoming melody by a user.

In recent years, mobile phones such as mobile phones and PHS (Personal Handyphone System) phones have been rapidly spreading, and various technical developments have been made. In particular, recent portable telephones are designed to generate a user's desired melody sound instead of a simple beep sound or an electronic sound called "beep" as an incoming sound, and a popular or favorite song can be used as an incoming melody. In this case, the melody of a large number of pieces of music is registered and stored in the cellular phone as an incoming melody in advance, and the user can select and use a favorite from among these many incoming melodies. Since the selection of the incoming melody can be made by the user at any time, it is also possible to change the incoming melody every day or every week. In addition, depending on the type of cellular phone, a wireless connection to a telephone line network can be used to access a music transmission center or an incoming melody center that stores various music data, select a desired melody, and download the music data. There is also.

In this case, the user can select and watch the incoming melody by the mobile telephone. In this case, the user may listen to the desired incoming melody. However, since a conventional mobile phone is configured to generate a melody for viewing on the incoming speaker, a very loud sound may be generated and cause inconvenience to those around them. have. In order to prevent such a situation, the user himself operates the cellular phone, lowers the incoming volume once, selects and views the incoming melody, and after the selection ends, the user operates the cellular phone again to restore the incoming volume. Need to be restored. For this reason, in the conventional cellular phone, the user has complicated operation at the time of selecting and viewing an incoming melody.

The present invention has been made in consideration of the above circumstances, and an object thereof is to provide a portable telephone capable of converting the volume of the incoming melody into the amount of noise by a very simple operation.

SUMMARY OF THE INVENTION The present invention provides a mobile phone capable of converting a volume of an incoming melody or the like into a noise level with a simple operation, and a method for switching the volume thereof, wherein the mobile phone includes at least a first speaker for generating a voice at a desired volume. Compared with the credit speaker and the first speaker, a second speaker (earpiece speaker) which generates sound at a noise level is incorporated.

It is an object of the present invention to generate a melody signal by reading the melody data from a memory that stores melody data relating to a desired piece of music in advance, and to switch the output destination of the melody signal in accordance with a user's operation. This melody signal is selectively supplied to either the first speaker or the second speaker. The melody signal may represent not only the incoming melody generated automatically at the time of incoming call, but also the melody and the sound of the desired music selected by the user.

That is, when the user operates the ring tone switch button provided in the cellular phone, the melody signal is automatically supplied to the second speaker, thereby reproducing with a noise level.

Moreover, you may make it the selection situation of the output destination of a melody signal on the screen of the liquid crystal display of a mobile telephone. As a result, the user can easily recognize the currently selected speaker.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. 1 is a block diagram showing a hardware configuration of a mobile phone according to an embodiment of the present invention, and FIG. 2 is a front view showing the appearance of the same mobile phone.

RAM for random access memory. A battery backup is attached to this RAM 13, and music data indicating an incoming melody relating to a plurality of music pieces can be stored. Reference numeral 14 denotes an operation input unit, and is composed of various buttons and switches arranged on the front surface of the case of the cellular phone as shown in FIG. For example, the off-hook button 14a, the on-hook button 14b, and a numeric key (so-called ten keypad) 14c are arranged on the front side of the cellular phone case, and the ring tone is switched at a predetermined position on the side of the case. The button 14d is provided. Reference numeral 15 denotes a display portion composed of a liquid crystal display and a display control circuit.

Reference numeral 16 denotes a (wireless) communication unit, which carries transmission data on a carrier wave, transmits the data from the antenna 17, and demodulates the received signal (i.e., an incoming signal) received through the antenna 17 to the CPU 11 Or outputs to the voice processing unit 19. The voice processing unit 19 is connected with the microphone 20 and inputs a voice signal which is collected by the microphone 20 and converted into an electrical signal (analog). Therefore, the speech processing unit 19 converts the input speech signal into a digital signal and compresses it to generate transmission data. The transmission data is sent to the communication unit 16. The communication unit 16 also outputs the incoming data obtained by demodulating the incoming signal to the voice processing unit 19. The audio processing unit 19 digitally and analog-converts the incoming data to generate a sign signal, and outputs it to the earpiece speaker 24 through the mixing circuit 22 and the amplifier 23. Reference numeral 25 denotes a ringing tone generator, and generates a ringing melody signal in accordance with an instruction from the CPU 11, and sends it to the switching circuit 27. The switching circuit 27 selectively sends the ringing melody signal from the ringing tone generator 25 to the amplifier 28 or the mixing circuit 22 in accordance with an instruction from the CPU 11. The amplifier 28 amplifies the incoming melody signal supplied through the switching circuit 27 and outputs it to the incoming speaker 29.

Next, the operation of the cellular phone according to the present embodiment will be described.

First, the operation | movement at the time of an incoming melody selection and viewing is demonstrated with reference to the flowchart of FIG.

The user first operates a predetermined key in the numeric key 14c of the operation input unit 14 to designate an incoming melody selection / viewing mode. Upon detecting this key operation, the CPU 11 displays the music data, the music number, and the music name of many incoming melodies stored in the RAM 13 on the screen of the display unit 15. When the user operates the predetermined numerical key 14c to select the desired music by viewing this screen, the determination result of step Sa1 becomes "YES", and the music number selected in the next step Sa2 is specified in RAM 13. It is stored in the area. In step Sa1, when the user has not selected the music, that is, when the determination result is "NO", the flow skips step Sa2 and proceeds to step Sa3. In this case, the previously set music number remains in the specific area of the RAM 13.

Next, a character string " incoming output selection, usually an earpiece " as shown in FIG. 2 is displayed on the screen of the display unit 15. FIG. In step Sa3, a determination is made as to whether or not the user who saw this display has operated the ring tone switching button 14d. On the screen described above, a mark is displayed on the left side of the character strings of "normal" and "earpiece", and it is possible to determine which one is selected. In the case of FIG. 2, since the mark of a black point is displayed on the left side of "normal", "normal" is currently selected. In addition, the above-mentioned selection can be switched by operating the ring tone switching button 14d. When the user operates the ring tone switching button 14d in step Sa3, the flow advances to step Sa4, and the CPU 11 outputs a switching signal to the switching circuit 27, while simultaneously displaying " on the screen of the display unit 15 " Black mark on the left side of the earpiece. As a result, the output destination of the switching circuit 27 is switched from the amplifier 28 side to the mixing circuit 22 side. If the user does not operate the ring tone switching button 14d in step Sa3, since step Sa4 is skipped, the switching operation of the switching circuit 27 is not performed, and the output of the ring tone generator 25 is output to the amplifier 28. Is supplied. In step Sa5, it is determined whether or not the user has instructed viewing by operating the numeric keys 14c of the operation input unit 14. If the determination result is "YES", the flow advances to step Sa6. If NO, the flow advances to step Sa7.

As described above, the music number selected by the user is stored in the specific area of the RAM 13, and in step Sa6, the CPU 11 reads out the music data indicated by the music number from the RAM 13 and rings. Output to the generator 25. The ring tone generator 25 writes the music data supplied from the CPU 11 into a melody (not shown) inside. Thereafter, the ringing tone generator 25 generates the ringing melody signal based on the music data, and outputs the ringing melody signal to the amplifier 23 through the switching circuit 27 and the mixing circuit 22. The amplifier 23 amplifies the incoming melody signal and outputs it to the earpiece speaker 24. As a result, the earpiece speaker 24 generates an incoming melody selected by the user. In the above case, since the incoming melody is generated from the earpiece speaker 24, not the incoming speaker 29, the user listens to the earpiece to watch the incoming melody. As a result of viewing, when the user determines that the incoming melody is good, the setting of the incoming melody is completed by operating a predetermined key of the operation input unit 14. The CPU 11 receives the completion of the incoming melody setting, generates a switching signal, and outputs it to the switching circuit 27. As a result, the switching circuit 27 switches the output destination from the mixing circuit 22 to the amplifier 28, and as shown in step Sa7, the pronunciation operation of the cellular phone returns to the normal state.

Next, the operation at the time of incoming call of the cellular phone will be described with reference to the flowchart of FIG.

If the cellular phone has an incoming call, the incoming signal is received by the antenna 17 and demodulated by the communication unit 16. The incoming data obtained by the demodulation is sent to the CPU 11. The CPU 11 stores the telephone number of the caller included in the incoming data in the RAM 13, and then issues a ring tone generation command and sends it to the ring tone generator 25. FIG. In response to this ring tone generation command, the ring tone generator 25 generates an incoming melody signal corresponding to the music number currently stored in a specific area of the RAM 13, and through the switching circuit 27 and the amplifier 28. Output to the incoming speaker 29 (see step Sb1). As a result, the incoming melody is generated by the incoming speaker 29.

In step Sb2, the CPU 11 determines whether or not the ring tone switching button 14d has been operated by the user. If the ring tone switching button 14d is not operated, the flow skips step Sb3 and proceeds to step Sb4. When the ring tone switching button 14d is operated, the flow advances to step Sb3, and a switching signal is output from the CPU 11 to the switching circuit 27. By this switching signal, the output destination of the switching circuit 27 is switched from the amplifier 28 side to the mixing circuit 22 side. As a result, the incoming melody is automatically generated by the earpiece speaker 24 in the amount of noise. The user listens to the earpiece of the mobile phone and hears the incoming melody. In that case, when the user presses the off-hook button 14a of the operation input unit 14, the determination result of step Sb4 becomes "YES" and flows. Proceeds to step Sb5. That is, when the CPU 11 detects the operation of the off-hook button 14a, the CPU 11 issues a ring tone stop command and outputs it to the ring tone generator 25. As a result, the occurrence of the incoming melody by the earpiece speaker 24 of the cellular phone stops.

After the above step Sb5 is finished, the flow advances to step Sb6, where the call processing is executed by the CPU 11. That is, the CPU 11 issues a line connection instruction and sends it to the voice processing unit 19 and the communication unit 16. The line connection instruction enables line connection between the cellular phone and the source telephone, thereby enabling a call. In other words, the voice of the user of the mobile telephone collected in the microphone 20 is wirelessly transmitted to the telephone of the originator by the voice processing unit 19, the communication unit 16 and the antenna 17. The voice data transmitted from the source is decoded and output from the voice processing unit 19 as a voice signal. The voice signal is sent to the earpiece speaker 24 through the mixing circuit 22 and the amplifier 23, and the voice of the source is pronounced by the earpiece speaker 24. When the user who needs to end the above call processing presses the on-hook button 14b, the determination result of step Sb7 becomes "YES", and the flow advances to step Sb8. In other words, the line cutting process is performed by the CPU 11. When the output destination of the switching circuit 27 is on the mixing circuit 22 side, the CPU 11 outputs a switching signal to return the pronunciation operation of the cellular phone to the normal state.

Next, the operation at the time of call origination will be described. At the time of the call, the user operates the numeric key 14c of the operation input unit 14 to input the other party's telephone number, and then presses the off hook button 14a. As a result, the CPU 11 stores the input telephone number once in the RAM 13 and then outputs it to the communication unit 16. The communication unit 16 carries data of an input telephone number on a carrier wave and wirelessly transmits the data to a base station or the like. The outgoing data is relayed on the telephone line network and sent to the telephone station, which makes a line connection between the caller's cellular phone and the other party's telephone. As a result, the user of the cellular phone can talk to the other party. That is, the voice of the user is sent to the other party by the microphone 20, the voice processing unit 19 and the communication unit 16, while the other party's voice is received through the antenna 17, and then the communication unit 16, It is delivered to the user by the voice processing unit 19 and the speaker 24.

As described above, according to the embodiment shown in Figs. 1 and 2, the user simply operates the ring tone switch button 14d disposed on the side of the case of the cellular phone, and simply changes the speaker to generate the ringing melody. Can be switched from the incoming speaker 29 to the earpiece speaker 24 set to the amount of noise. By such a simple operation, the user of the cellular phone can view, select, and set the incoming melody without disturbing those around him.

In the present embodiment, the incoming melody signal is output to the earpiece speaker 24 with a low volume when viewing and selecting the incoming melody. However, the present invention is not necessarily limited to such an embodiment. For example, when the ringing tone switching button 14d is operated by the user, it is also possible to automatically reduce the volume of the ringing melody signal and send it to the ringing speaker 29. In this case, the user may listen to the incoming melody instead of the earpiece speaker 24 and watch the incoming melody. Incidentally, in the present embodiment, the switching of the volume of the incoming melody has been described, but the object for switching the generated volume is not limited to the incoming melody. That is, you may change the volume of melody, a musical sound, etc. of the music to be pronounced irrespective of an incoming call. In recent years, a mobile phone may be used as a player of a music downloaded from a music transmission center rather than as a telephone device. In this case, the user automatically adjusts the volume of the music by simple operation without causing trouble to those around him. Enjoy.

Various processes of the mobile phone realized in the embodiment of the present invention, in particular, a process at the time of selection and viewing of an incoming melody or the like, programs or data for the volume switching method, and various storage media, for example, a memory. It is also possible to store in a so-called digital storage medium such as a guide and attach it to a normal cellular phone to achieve the functions of the present embodiment. The button and the switch related to the volume switching operation need not be limited to the ring tone switching button 14d, and may be a predetermined button in the operation input unit. In that case, the volume switching operation detection function is automatically assigned to a predetermined button in the operation input unit by the program.

As described above, according to the present invention, it is possible to obtain the effect that the generated volume of the incoming melody and the like can be automatically switched to the noise level by a very simple operation.
