Description

Detailed Description of the Invention

[0001]

This invention relates to telephones.

[0002]

2. Description of the Related Art In a telephone having a holding function, a signal of a holding tone is output to a line during holding so that the other party of the telephone is notified that the telephone is on hold. Moreover, a melody (musical piece) and various sound effects are used as the hold sound.

Further, there is also a telephone in which a melody or a sound effect is also produced as a ringer sound when an incoming call arrives.

[0004]

However, most models have only one type of hold tone. In addition, although some models have a plurality of holding sounds, the user has to select the holding sound to be output. Since such an operation is not performed frequently enough for the user to remember, it is necessary to check the instruction manual when changing the hold tone, which is troublesome.

As a result, even if a plurality of holding tones are prepared, the holding tone to be actually used is often left as it is at the time of factory shipment. Alternatively, even if the hold tone is selected when the telephone is purchased, it often remains as it is after that. That is, even if a plurality of holding sounds are prepared, they are often not used effectively.

For this reason, the on-hold tone is always the same, which causes a case that "when holding, the same song is always heard and it is unpleasant".

The same applies to ringing sounds,
Even if a plurality of ringing tones are prepared, they are rarely used effectively, so that the same problem is caused.

The present invention is intended to solve the above problems.

[0009]

Therefore, in the present invention, when the reference numerals of the respective parts correspond to the embodiments described later, the melody circuit 21 and the clock circuit 44 are provided, and the melody circuit 21 is external. Has data of a plurality of songs that can be selected by a signal from, and at the time of holding or receiving a call, one of the data of the plurality of songs is selected and taken out as an audio signal according to the time indicated by the clock circuit 44. The on-hold tone or the ringer tone at the time of an incoming call is obtained from the audio signal.

[0010]

When the time is changed according to the time measured by the clock circuit 44, the holding sound and the ringer sound are automatically changed.

[0011]

Further, 30 is a microcomputer for system control, which includes a CPU 31, a ROM 32 in which various programs are written, a RAM 33 for work area and data holding, an input port 34, and an output port. 35 and.

In this case, the ROM 32 is provided with a processing routine 100 as shown in FIGS. 3 and 4, for example, as a part of the program written therein. Further, the ROM 32 is provided with, for example, as shown in FIG. 2, a table MLDTBL indicating the correspondence between the music number N and the month MNTH to which the music of the music number N corresponds.

Also, through the ports 34 and 35, the CPU
Predetermined signals are accessed between 31 and the circuits 13, 15, 16, 21, 22.

Further, the microcomputer 30 includes
Various operation keys 4 such as dial keys 41 and hold keys
2. A switch 43 for detecting on-hook / off-hook of the handsets 11 and 12 is connected, and a clock circuit (real-time clock) 44 is connected. The clock circuit 44 is composed of, for example, a one-chip IC, and measures the current time, that is, the year, month, day, hour, minute, and second,
The time output is supplied to the microcomputer 30.

The operation of the telephone 10 is performed by the CPU
By executing the processing of the routine 100, the processing is performed as follows.

[Standby] When the power of the telephone 10 is turned on, the processing of the CPU 31 starts from step 101 of the routine 100, and then, at step 102, each part is initialized. In this case, the muting of the amplifiers 13, 15 and 22 is turned on as a part of this initialization, and the line interface circuit 16 is put into the off-hook state.

Next, in step 103, the presence / absence of a ringer signal at the time of an incoming call is determined through the interface circuit 16, and when the ringer signal is not obtained, that is, when there is no incoming call, the process proceeds from step 103 to step 1.
Go to 04. Then, in this step 104, by checking the on / off state of the switch 43, it is judged whether or not the handsets 11 and 12 are off-hooked. If not off-hooked, the process proceeds from step 104 to step 105. .

Then, in step 105, the key 4
Of the two, it is checked whether or not the registration key 42R for setting or registering the operation mode or the like has been pressed. If not, the process returns from step 105 to step 103. Therefore, during standby, steps 103 to 105 are repeated, and the standby state is realized.

[Incoming Call] When there is an incoming call in the above-mentioned standby state, this is detected in step 103, and the process proceeds from step 103 to step 111,
In this step 111, the muting of the amplifier 22 is turned off.

Next, in step 112, the "month" of the date counted by the clock circuit 44 is calculated in the table MLDTBL.
The table MLDTBL is referenced using the value MNTH of
The "month" (value MNTH) is converted into the corresponding song number N.
For example, if the “month” of the date measured by the clock circuit 44 is
In the case of December, MNTH = 12 is set, the table MLDTBL is referred to, and N = 5 is set corresponding to MNTH = 12. Then, the tune number N is specified for the melody circuit 21, and
Reading is instructed.

Therefore, the melody circuit 21 outputs the analog audio signal of the Nth song. For example, if N = 5 in FIG. 2, the analog audio signal of the Christmas song will be output.

Then, the analog audio signal from the melody circuit 21 is passed through the amplifier 22 to the speaker 2
3, the music by the analog audio signal is output from the speaker 23, that is, the music number N.
Is output as a ringer sound, and the incoming call is announced.

In this way, the ringing by the incoming call is the music number N.
No. of songs, that is, ringing sounds of songs that match the season.

Further, the processing of the CPU 31 is step 11
2 is followed by step 113, in which step 113
At, it is determined whether or not the ringer signal for announcing the incoming call is still detected. When the ringer signal is obtained, the process proceeds from step 113 to step 114. Then, in this step 114, the switch 4
By checking the on / off state of No. 3, it is judged whether or not the handsets 11 and 12 are off-hooked. If not, the process is step 114.
Returns to step 113.

Therefore, when the incoming call request from the other party continues and the handsets 11 and 12 remain on-hook, steps 113 and 114 are repeated and the speaker 23 plays the song in step 112. It is output as a ringer sound.

Then, in order to receive the incoming call, the handset 1
Off hooking 1 and 12 this is detected in step 114 and the process proceeds from step 114 to step 1
In step 115, the amplifier 22
The muting is turned on and the melody circuit 21 is set to the stop mode. Therefore, the song for the ringer sound has stopped.

Then, in step 116, the amplifier 1
The mutings 3 and 15 are turned off, and the interface circuit 16 is set to the line capturing state.

Therefore, after that, it is possible to talk with the other party who made the call as follows.

When the other party goes on-hook while steps 113 and 114 are repeated, the line 9
Since the ringer signal from 9 is not obtained, this is detected in step 113, the process returns from step 113 to step 103, and the telephone set 10 is in the standby state again.

[During a call] During a call, the voice signal of the user is sent to the line 99 through the signal line of the transmitter 11 → amplifier 13 → addition circuit 14 → interface circuit 16. Further, the voice signal from the other party is supplied to the handset 12 through the signal line of line 99 → interface circuit 16 → amplifier 15.

Therefore, the transmitter 11 and the receiver 12
You can use to call the other party.

Then, during this call, the processing of the CPU 31 proceeds to step 121. At this step 121,
It is checked whether the hold key 42H of the operation keys 42 has been pressed. When it is not pressed, the process proceeds from step 121 to step 122,
In this step 122, by checking the on / off state of the switch 43, it is judged whether or not the handsets 11 and 12 are on-hook. If they are not on-hook, the process returns from step 122 to step 121.

Thus, during a call, steps 121, 1
22, the hold key 42H and on-hook are checked.

[Hold] When the hold key 42H is pressed during a call, this is detected in step 121, and the process proceeds from step 121 to step 123, in which the muting of the amplifiers 13 and 15 is turned on. Then, in step 124, as in step 112, the “month” of the date counted by the clock circuit 44 is used as the value MNTH of the table MLDTBL, and the table MLDTBL is referred to. (Value MNTH) is converted to the corresponding music number N. And the melody circuit 2
For 1, the music number N is specified and reading is instructed.

Therefore, the melody circuit 21 outputs the analog audio signal of the Nth song.

Then, the analog audio signal from the melody circuit 21 is sent to the line 99 through the adding circuit 14 and the interface circuit 16. Therefore, the other party of the telephone can hear the hold sound by the analog audio signal, that is, the song of the song number N, for example, a Christmas song.

At this time, the analog audio signal from the melody circuit 21 is supplied to the handset 12 through a stage subsequent to the muting stage of the amplifier 15, and the hold tone is also output from the handset 12.

Thus, during the hold, the music of the music number N, that is, the music suitable for the season is output as the holding sound.

During this time, the processing of the CPU 31 proceeds to step 125, and in this step 125, step 125 is repeated until the hold key 42H is pressed again, waiting for an instruction to release the hold.

When the hold key 42H is pressed, the process proceeds from step 125 to step 126. In step 126, the melody circuit 21 is set to the stop mode, and then in step 127, the amplifiers 13 and 1 are set.
The muting of 5 is turned off, and then the process returns to step 121.

Therefore, the hold is released and the call can be made again with the caller.

[End call] When the handsets 11 and 12 are hooked on during a call, this is detected in step 122, and the process proceeds from step 122 to step 131. Then, in this step 131, the amplifier 1
Muting operations 3 and 15 are turned on, and the call termination processing such as opening the line of the interface circuit 16 is executed. After that, the processing returns to step 103. Therefore, thereafter, the telephone set 10 is in the standby state again.

[Call] When the handset 11 or 12 is off-hook in the standby state, this is the step 10
4, the process proceeds from step 104 to step 141. In step 141, the muting of the amplifiers 13 and 15 is turned off, and
Calling processing is performed such that the interface circuit 16 is in the line capturing state. After that, when the telephone number of the other party is input from the dial key 41, the dial signal is sent from the interface circuit 16 to the line 99, and the telephone of the other party is called.

In the meantime, the process proceeds to step 141.
From step 121 to step 121, after that, when the other party answers the call, the call is ready as described above.

When the registration key 42R of the operation keys 42 is pressed in the [setting] standby state, this is detected in step 105, and the process proceeds from step 105 to step 151. And this step 15
In 1, the corresponding setting or registration is executed according to the key pressed after the registration key 42R.

For example, when the "4" key of the dial key 41 is pressed after the registration key 42R, the time setting mode of the clock circuit 44 is set. For example, the dial key 41 is changed from "0" to "1" to ""0" → "1" → "1" → "4" →
When "0" → "0" are pressed in sequence, the clock circuit 44 displays "01/01/14 4:00
It is set to "0 minutes".

When this step 151 is completed, the process returns to step 103 and the standby state is resumed.

[Others] In the above description, the hold sound and the ringer sound can be changed depending on the time of day. It is also possible to change only one of the holding sound and the ringer sound depending on the time (month, day or hour / minute) and not the other. Furthermore, when a predetermined setting operation is performed, the music number N can be fixed to the set music regardless of the time.

It is also possible to make the music number N random so that it is impossible to know which music will sound. Further, when the user specifies a time or a song, for example, if a birthday and a song are specified, the song specified for the birthday can be output.

[0055]

According to the present invention, the on-hold tone and the ringer tone automatically change depending on the season and the time of day.
There is no need to look up the instruction manual to change them. Also, since it changes depending on the season and the time of day, it is less likely to give an unpleasant feeling when holding or receiving a call. Rather, the user can feel the enjoyment, the fun, the unexpectedness, the sense of the season, and the like.

Further, since the clock circuit 44 and the like necessary for realizing the above functions are often already mounted in many telephones, they can be easily realized and the cost increase can be suppressed.
