Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone, and more particularly to a portable telephone, a stationary telephone and a cordless telephone handset capable of registering a notification sound other than an incoming call notification sound prepared in advance.

[0002]

2. Description of the Related Art A telephone sets a ring tone in response to an incoming call from an external telephone. When the telephone is a cellular phone such as a cellular telephone or a PHS terminal, when the incoming call data is received from the wireless base station, the incoming call notification operation is performed by receiving the incoming call tone data stored in an appropriate format in the built-in memory. This is performed in the process of reading, converting this data into a voice signal and outputting the voice from the speaker. The ringing tone data is a data string of numbers and symbols associated with the DTMF signal, and a predetermined DTMF signal is acoustically output by applying this data string to the built-in tone generator. Usually, a mobile phone is provided with a plurality of types of incoming call notification sounds in advance, and the user can freely set any incoming call notification sound among them. Further, if the DTMF signal is associated with the ringing tone data so as to have a predetermined melody, the melody can be acoustically output. Therefore, some melody can be selected as the incoming call notification tone.

On the other hand, in the case of a general subscriber telephone connected to a public line network, an incoming call signal from an exchange is received, and a ringing tone generating circuit (ringer circuit) operates by using the signal as a power source to make a predetermined incoming call. Sound is output from the speaker. Digital telephones directly connected to the ISDN network are I
Upon receiving digital incoming data from the SDN network, the ringer circuit is operated by an internal power source to output a ring tone. In the case of an analog telephone connected to the ISDN, the TA (terminal adapter) operates the ringer circuit by generating the incoming call signal and outputting it from the terminal to which the analog telephone is connected.

Further, when the stationary telephone is a cordless telephone, a cordless telephone slave unit having the stationary telephone as a base unit receives a calling signal from the base unit by wireless communication and has a built-in ringer circuit. Is activated to acoustically output a predetermined incoming call notification sound.

[0005]

At present, mobile phones are
It is said that about 40 million units are operating. Therefore, it is highly possible that there are multiple people who own mobile phones within a narrow range. Therefore, when the incoming call notification sound of another person's mobile phone sounds, other people in the vicinity "misidentify" that it is an incoming call of their own mobile phone and take out the silent mobile phone. Sometimes. Certainly, many incoming call notification sounds are prepared in advance for mobile phones. However, there are many cases where the preference of the incoming call notification sound is similar to each other, and it is difficult to know whether the incoming call notification sound is the ringtone of the user's mobile phone or not by a slight difference in rhythm or frequency. First of all, how many people know exactly the rhythm and melody of the ringtone of their mobile phone. Therefore, the above-mentioned “misidentification” still occurs.

Therefore, recently, there is a mobile phone having a ringtone storing function capable of registering an incoming call notification sound other than the prepared ones so that it can be clearly distinguished from the ringtones of other mobile phones. This is to create an incoming call notification sound uniquely according to the scale of a predetermined DTMF signal. Specifically, when a predetermined user input is received from a user interface such as an operation key, the operation mode setting is switched to a ringtone storing mode in which an incoming call notification sound can be registered, and a predetermined DTM is set.
A key (such as a numeric keypad) to which the F signal is assigned is regarded as a keyboard corresponding to a predetermined scale, and the keys are sequentially pressed so that the rhythm or melody intended by the user is obtained. Then, the numbers and symbols of the keys pressed in this order are associated with the time series (the time when the key is pressed, the duration of pressing the key, etc.) as data (DTMF specifying data) for specifying the DTMF signal. The data is stored in a storage unit such as RAM as ring tone data. If the stored melody is set as a ring tone, the ring tone data "composed" by the ring tone data is read and given to the tone generator at the time of an incoming call. However, when a user registers a ring tone, he or she must first "compose" a rhythm or melody based on the DTMF signal. It is difficult to make an incoming call notification sound without the user's knowledge of composition. A score is required even when inputting a ready-made song such as a popular song. In order to "copy" without music, it still requires musical talent.
Of course, for users of mobile phones equipped with a ring tone storage mode, books in which the rhythms of ready-made songs and incoming call notification tones are described by numbers or key sequences corresponding to DTMF signals are commercially available. If you use this book, you will be freed from the work of "composing". However, the key operation required to register the incoming call notification sound is required 100 times or more for a long melody. This is cumbersome and takes a lot of time to register. There is a high possibility that you will make a mistake when pressing the key.

Further, in Japanese Patent Laid-Open No. 10-13499, an audio signal input from an external audio device is A / D converted and digitally recorded, and the audio data is D / A when an incoming call is received.
A technique for a mobile phone of a type that is converted and used as a notification sound is disclosed. "Record" this ringtone
With a mobile phone of the type you can register an incoming call notification sound with a simple operation. However, a large capacity memory is required to store a large amount of voice data. MPEG
Even if a voice data compression technique such as is applied, an expensive dedicated IC must be built in for encoding. In any case, a significant cost increase is inevitable,
Not practical.

On the other hand, general subscriber telephones are supposed to be used indoors. In addition, the ringer circuit is operated by the power supply from the exchange because of the necessity of allowing incoming calls and calls even during a power failure. Therefore, there is usually only one type of ringtone. At most, it is limited to only a few types with different frequencies and intermittent sound patterns that can be selected by the changeover switch. However, it would be unpleasant if the electronic sound of the same pattern always sounded, and if the ringing sound of a popular melody sounds, "mechanical" incoming call notification should be fun. In addition, even for cordless handsets with built-in power sources, ringtones are limited because they are used indoors. Therefore,
It has the same problems as stationary phones.

In the case of stationary telephones and cordless telephone handsets used as PBX terminals, many extension telephones of the same model are used in a narrow range in offices and the like. Therefore, the same "misidentification" as the above-mentioned mobile phone may occur.

Therefore, an object of the present invention is to provide a telephone which can easily register a unique incoming call notification sound without increasing the cost.
