Description

  The present invention relates to a mobile phone having an incoming call notification function, and more particularly to a mobile phone having an incoming call notification function using a degraded noise audio signal obtained by making a band-divided voice noise.

  2. Description of the Related Art Conventionally, in a mobile phone, a ring tone pattern stored in a memory accommodated in the mobile phone is changed based on setting information input from an operation key by a user, and when a call is received or when a mail is received by a mail function In addition to the ringing melody (ringtone) that has been set, and the ringing tone pattern other than the ringing tone pattern set from the beginning and the desired ringing tone pattern created by the user such as voice or melody, the browser function Thus, a new ring tone pattern is downloaded as a melody data from a server on the network, stored in the memory, and set as a ring tone or a mail reception tone.

  Japanese Patent Application Laid-Open No. 2004-133867 discloses a technical disclosure of a mobile communication terminal device equipped with a tone generator that changes a timbre that rings based on timbre information set in melody data acquired from a server device.

  In the above technology, the ring tone is sounded by various tones generated by the tone generator, and when the ring tone is sounded at the time of incoming call or mail reception, it can be sounded by various tones. Melody can be played, and the timbre is dynamically changed, so that the area occupied by the memory for timbre information can be reduced. Furthermore, there is a description that the troublesomeness of resetting the timbre for each music piece is eliminated, and the timbre is set for each phrase or for each musical scale even when playing one musical piece.

In addition, for the purpose of reproducing uncomfortable sounds, for example, a speech synthesis LSI such as AudioEngine ^™ (registered trademark) has been developed and installed in mobile phones. Even when used, ringtones such as ringtones were often annoying for those around.

  Furthermore, among the various functions of mobile phones, it may be convenient for the person to use the "function to read out the other party's name or nickname by voice when receiving a call" If the voice of a character such as “Call from Mr. Nakamura” is spoken during the meeting, there is a possibility of buying a bag at the meeting and being embarrassed.

  On the other hand, in Patent Document 2, a speech signal is divided into a plurality of band signals, and after extracting envelopes, each envelope is extracted, and then a noise source signal is added to a band filter unit having a plurality of band filters, Hearing aids, training devices, game devices, and sound output devices that use degraded noise speech signals that have been extracted from noise source signals and accumulated by multiplying the output of each band filtering unit and noise source components. It is disclosed.

  FIG. 5 is an example of a block diagram of a degraded noise audio signal described in Patent Document 2. In this example, only one of the degraded noise audio signal generation circuits divided into a plurality of parts is shown, but in reality the output signals of a plurality of multipliers 107 are added by the adder 108.

  As this operation, first, a necessary frequency band is extracted by the audio signal extraction unit 102 from the input audio signal from the degraded noise audio signal generation microphone 101, and further, a predetermined frequency is obtained by the band filtering unit 103 having a plurality of band filters. After extracting the signal of the band, the envelope extraction unit 104 extracts the envelope of the band signal of each frequency band, while the band filtering unit 106 removes the noise generated from the noise source 105 in the same frequency band as the band signal. Only the noise signal having the above is extracted and multiplied by the multiplication unit 107 together with the signal from the envelope extraction unit 104.

Signals divided into a plurality of frequency bands are processed by a plurality of multiplication units 107, added by an addition unit 108, amplified by an amplification unit 109, electromechanically converted by a speaker 110, and output as sound. .

  However, in Patent Document 1, it is difficult to distinguish who received an incoming call even if a tone is generated by a tone generator, and Patent Document 2 only discloses the use of degraded noise speech as training for hearing loss. There is no disclosure or suggestion about specific applications.

  Therefore, the present inventor notices that when a deteriorated noise voice signal is heard by a large number of people at the same time, it is heard as noise by a person other than the person familiar with the deteriorated noise sound in advance. For example, the person can obtain information on who is receiving the call, and the other person can reduce the discomfort of the incoming call notification voice of the mobile phone in the train or the like. Made.

As means for solving the above problems, in the present invention, in a mobile phone having a browser function, a telephone function, and a display function,
A function for detecting a telephone call by the telephone function or a mail incoming function by the browser function and the display function, a function for detecting a telephone call or a party to whom a mail is transmitted, and a notification of the name of the partner to be transmitted using degraded noise voice It has a function to do. Thereby, even when a large number of people hear the ringtone at the same time, the ringtone can be heard as noise except for the person who has been used to the deteriorated noise voice in advance, so that the nuisance to the surroundings can be reduced.

  The function of notifying the name of the other party who has transmitted using the degraded noise voice is a function using a degraded noise voice signal generation server connected via a network. As a result, even if the mobile phone main body does not have a degraded noise voice signal generation function, the degraded noise voice signal can be used as a ringtone.

  Furthermore, the function of notifying the name of the other party who has transmitted using the degraded noise voice is a function built in the mobile phone body as a degraded noise voice signal processing circuit. This makes it possible to generate a degraded noise audio signal from the mobile phone even if the browser function has a problem.

  In the incoming notification of the mobile phone, the number of frequency band filters that generate the degraded noise audio signal is increased or decreased according to the number of incoming calls. This makes it difficult to get tired since the incoming call notification voice can be changed.

  Further, when the incoming notification of the mobile phone is made, the boundary frequency of the frequency band filter used to generate the degraded noise audio signal is changed according to the number of incoming calls. This makes it difficult to get tired since the incoming call notification voice can be changed.

  In addition, when the mobile phone is notified of an incoming call, the content of the deteriorated noise audio signal can be switched between non-display / display of the display unit of the mobile phone according to the number of incoming calls. As a result, even if the deteriorated noise audio signal cannot be easily heard, it can be quickly confirmed visually.

  The mobile phone of the present invention can be heard as a noise resembling voice for those who are not used to it, and a deteriorated noise signal that can be heard as sound for those who are used to it as an incoming call notification sound and other ringing sounds. This has the effect of reducing the nuisance to the surroundings, such as people other than the person being concerned about the incoming voice from the mobile phone in meetings and gatherings where people gather.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings. In the following description, components having the same function are denoted by the same reference numerals, and repeated description thereof is omitted.

  Further, in the following embodiment, an example applied to a mobile phone is shown. However, the phone according to the present invention is not limited to a mobile phone, but a PDA, a wristwatch type mobile terminal, a hearing aid having a mobile phone function, a bone conduction mobile phone, etc. The present invention can be applied to any portable communication terminal having a telephone function.

  FIG. 1 is a block diagram showing a schematic configuration diagram of a cellular phone when the cellular phone body according to the present invention has a function of generating a degraded noise audio signal.

  The cellular phone 1a is provided with an antenna 10, an RF circuit 11, a signal processing unit 12, and a CPU 17 for controlling them as in the conventional telephone. The CPU 17 includes a display device 18, a keyboard 19 as input means, a main memory. A memory 20 as means and a camera 21 as input means such as a QR code are connected.

  The signal processing unit 12 includes an AD converter 13 that digitally converts an analog signal input from the microphone 15 and an analog conversion of the digital audio signal output from the signal processing unit 12 into an analog audio signal. A DA converter 14 for converting and driving the speaker 16 is connected.

  For example, as described in Patent Document 2, the signal processing unit 12 incorporates an algorithm for converting a voice signal input from the microphone 15 into a degraded noise voice signal. When the central processing unit 17 determines that the mobile phone 1a has been accessed from outside such as a call or mail, the ring tone setting becomes a degraded noise audio signal with reference to the ring tone setting parameter stored in the memory 20. If the signal processing unit 12 is set to the degraded noise voice signal generation mode, the ring tone data stored in the memory 20 is converted into a degraded noise voice signal by the signal processing unit 12, and then the DA converter 14. By transmitting data to the speaker 16, a degraded noise audio signal is output from the speaker 16.

  As a method for inputting voice data to be converted into a degraded noise voice signal, in addition to a voice input method from the microphone 15, a direct input method from an operation key 19 such as a keyboard, a method of storing in a memory 20, a camera 21 There are a method of reading from a QR code, a method of reading infrared data using an IrDa device 24, and a method of reading from an IC card using an IC card reader 22 or an NFC (Near Field Communication) device.

  In addition to the above, as a method for acquiring degraded noise voice signal conversion data from the outside of the cellular phone 1a, a mobile phone that can be browsed is used, and text data included in the browsed screen or e-mail is used. Then, it may be converted into a degraded noise voice signal by using the function of the mobile phone itself or by transmitting it to the degraded noise voice signal generation server 4.

  Further, in the case of a mobile phone with a camera, in addition to a method of reading the QR code and transmitting character data included in the QR code to a server to convert it into a deteriorated noise voice signal, for example, an OCR function can be used. By providing a function, a degraded noise voice signal may be generated using a character data such as a document photographed by the camera-equipped mobile phone and converted into character information by the OCR function.

  FIG. 2 is a conceptual diagram of a system according to another embodiment of the present invention. The mobile phone 1 does not have a degraded noise voice signal generation function, and an external degraded noise voice signal generation server is installed on a network such as the Internet. 2 is an example of a system that converts speech to degraded noise speech signals by placing.

  The cellular phone 1 communicates with the relay station 2 using radio waves having a predetermined frequency. The relay station 2 is connected to the Internet 3 via a network 3. Further, a deteriorated noise audio signal generation server 4 is connected to the Internet 3, and the audio signal received from the mobile phone 1 is converted into a deteriorated noise audio signal by a predetermined process and relayed via the Internet 3. The data is transmitted to the mobile phone 1 via the station 2.

  In the mobile phone 1 storing the deteriorated noise voice signal, for example, if the ringtone setting is set so that the deteriorated noise sound signal is sounded when an incoming call is received, the other mobile phone 7 relays from the relay station 8 to the relay station 2 and the mobile phone When calling 1, the degraded noise audio signal is used as an incoming call notification sound of the mobile phone 1.

  FIG. 3 is an example of a processing sequence at the time of the incoming call of the mobile phone in the first or second embodiment. When the incoming call operation is started in step S1, the mobile phone 1 enters a mode for waiting for an incoming call from the outside. When the incoming call is confirmed in step S2, the ring tone setting is read in accordance with the incoming call property in step S3. Further, in step S4, the frequency band filter of the deteriorated noise voice signal set for each transmission partner determined. And the ring tone data such as the frequency band setting for each frequency band filter are read into the signal processing unit 12. Using the ring tone data, in step S5, ring tone data (for example, “I'm a phone call from Mr. Rattan”) is converted into a degraded noise voice signal, and in step S6, the degraded noise voice signal is output from a speaker or the like. To do. If there is further ringtone data, step S6 is repeated until all ringtone data is processed, or the predetermined repetition process is completed, or the process is interrupted until the ringtone button is pressed, etc. repeat. Thereafter, in step S8, the incoming call notification is terminated and the voice call mode is switched. If the incoming call is not a voice call but a mail, the mail display mode is switched. Further, when the voice call or the received mail display work is completed, the process returns from step S9 to step S2 to enter a standby operation for the next incoming call.

  FIG. 4 shows a third embodiment of the present invention. As described in Patent Document 2, the sound quality of the degraded noise audio signal can be changed by changing the number of stages of the frequency filter. As an example of this embodiment, FIG. 4 shows an example in which two sets of frequency filtering sections 26 and 26a of three stages and four stages are used.

  When a telephone call is made from another mobile phone 7 to the mobile phone 1 via the relay station 2, the audio signal output from the audio signal extraction unit 2 inside the mobile phone 1 is transmitted from the frequency band filter 26 or the frequency. One of the bandpass filters 26 a is selected by the CPU 17 of the mobile phone 1. The envelope noise signal is extracted from the deteriorated noise voice signal output from the selected frequency band filter 26 or 26 a by the envelope extraction unit 27. On the other hand, a noise signal covering the frequency band of the frequency band filter 26 or 26a is output from the noise signal source 28, and a predetermined band is obtained by a band filter unit group 29 corresponding one-to-one with the frequency band filter 26 or 26a. A noise signal corresponding to is extracted.

  The envelope signal and the noise signal are subjected to a predetermined weighting, multiplied by the multiplication unit 30, and then accumulated by the addition unit 30 as a deteriorated noise audio signal obtained by noiseizing the sound source signal component. Generated.

  Also, in the above, for the purpose of giving variation to the deteriorated noise voice signal used as the ring tone, not all the frequency band filters installed in the mobile phone are always operated. For example, from the first to the fifth For incoming calls up to the first time, the number of operation of the frequency band filter is three, the number of incoming calls is four from the sixth to the tenth, and four from the eleventh to the fifteenth. It is also conceivable to increase or decrease the number of operations.

  Further, for the purpose of giving variations to the deteriorated noise voice signal used as a ring tone, as a method different from the above, the number of installed frequency band filters and the number of operating frequency band filters are fixed, and each frequency band filtered It is conceivable to change the boundary selection of the frequency band to be filtered by the filter. For example, when using four frequency band filters, the default frequency band is 0 to 600 Hz, 600 to 1500 Hz, 1500 Hz to 2500 Hz, 2500 Hz to 4000 Hz, and the frequency band boundaries are 0 to 800 Hz, 800 to 2000 Hz, There is a method of changing to 2000 to 3000 Hz and 3000 to 5000 Hz.

  As described above, it is possible to avoid making the ringtone of the mobile phone monotonous by changing the number of operating frequency band filters or the boundary of the frequency band according to the number of incoming calls. It becomes hard to get bored.

  FIG. 5 shows a fourth embodiment of the present invention. As described in Patent Document 2, the sound quality of the degraded noise audio signal can be changed by changing the frequency boundary of the frequency filter. As an example of this, FIG. 5 shows an example in which the setting of the frequency boundary of the frequency filter is selected from two parameters.

  When a call is made from another mobile phone 7 to the mobile phone 1 via the relay station 2, the CPU 17 of the mobile phone 1 responds to the audio signal output from the audio signal extraction unit 2 inside the mobile phone 1. Selects the band boundary parameter 34 or 34a of the frequency band filter 26. An envelope signal is extracted by the envelope extraction unit 27 from the degraded noise speech signal output from the frequency band filter 26 for which the band boundary parameter 34 or 34a is selected. On the other hand, a noise signal covering the frequency band of the frequency band filter 26 or 26a is output from the noise signal source 28, and a predetermined band is obtained by a band filter unit group 29 corresponding one-to-one with the frequency band filter 26 or 26a. A noise signal corresponding to is extracted.

  The envelope signal and the noise signal are subjected to a predetermined weighting, multiplied by the multiplication unit 30, and then accumulated by the addition unit 30 as a deteriorated noise audio signal obtained by noiseizing the sound source signal component. Generated.

  In the first to fourth embodiments described above, it is conceivable to use Internet telephone connection means such as SKYPE (registered trademark) capable of simultaneous calls by a plurality of callers. As a result, if both the mobile phone and the degraded noise audio signal generation server are connected to each other with SKYPE (registered trademark), the chat function of SKYPE (registered trademark) can be used. A chat using one-to-many interactive degraded noise voice becomes possible by converting the degraded noise voice signal into a degraded noise voice signal and playing it on the mobile phone. Also, as a method of inputting audio data to be converted into a degraded noise audio signal using the video function of SKYPE (registered trademark), a method of reading from a QR code by the camera 21 is also conceivable. Further, as described in the first embodiment, in addition to the voice input method from the microphone 15, the direct input method from the operation key 19 such as a keyboard, the method of storing in the memory 20, and the infrared data using the IrDa device 24. A reading method and a method of reading from an IC card using an IC card reader 22 or an NFC (Near Field Communication) device are also conceivable.

  In the first to fourth embodiments, for example, the number of bandpass filters and frequency band setting may be individually arranged by hardware, or dynamic reconfigurable (dynamic reconfiguration) can be applied not only to the bandpass filter but also to the signal processing unit 12. Configuration) If a chip is used, it is also possible to perform degraded noise audio signal processing by dynamically changing the circuit configuration dynamically so that optimum operation can be performed.

  An incoming call notification sound that can be recognized by anyone can be heard as a kind of music-like noise for those who are not familiar with degraded noise in meetings and public transportation that are annoying to others. By using a degraded noise voice signal that can be recognized as voice as an incoming call notification means, only the person familiar with the degraded noise voice can recognize the incoming call without disturbing the public order with respect to others. Can contribute to the maintenance of social order.
