Abstract

PURPOSE:To avoid trouble due to a ring tone at a time zone such as at night when the volume of a ring tone is desired to be small by changing the sound volume of the ring tone in response to the time when the ring tone is generated through the control of a built-in timer. CONSTITUTION:The timer 24 outputs a time of 24hr system based on a pulse of an oscillator 3 and the time is displayed on a time display section 8 through a switch 7. Comparators 9, 10 discriminate the time or not the time is within the set time by time set registers 5, 6 and when the time is outside of the range, an output of a flip-flop 11 is brought into 0 and a selector 13 selects a ring tone generating circuit 14. When the time is within the range, an output of the flip- flop 11 goes to 1, the selector 13 selects a ring tone generating circuit 15, by which the sound volume of the ring tone is changed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a ring tone generating device V built into a telephone or the like that adjusts the volume or tone of a ring tone depending on the time of day.

Conventional Structure and Problems Therein FIG. 1 shows a block diagram of a conventional telephone ringing tone generating device. In FIG. 1, 1 is a receiving device, and 2 is a ringing tone generating circuit. In FIG. 1, when a receiving device 1 receives a communication from a communication channel, the received signal is applied to a ringing tone generating circuit 2, and a ringing tone is generated. The ringing tone in the ringing tone generation circuit 2 has a single volume and tone. And this ringtone has an extremely loud volume that can be recognized even in daytime noise. However, when such a ringing sound occurs at night when surrounding noise is significantly reduced, there is a problem in that it is unreasonably loud and has a large impact on the surroundings.

OBJECTS OF THE INVENTION The present invention obviates these conventional drawbacks,
It is an object of the present invention to provide a ringing tone generation device built into a telephone or the like which has a built-in timer and can adjust the volume of the ringing tone according to the time when a ringing occurs by controlling the timer.

Structure of the Invention The present invention provides a timer that provides the current time, first and second time setting registers that are given arbitrary times and holds them, and a comparison between the values of the timer and the first time setting register. a first comparator that compares the values of the timer and the second time setting register; and a second comparator that compares the values of the timer and the second time setting register; A flip-flop to be reset, a receiving device that receives a message from a communication path and outputs a received signal, first and second ring tone generating circuits having different volumes or sound qualities, and a ring tone generating circuit based on the output value of the flip-flop. a selector for supplying a received signal output from the receiving device to the first or second ringing tone generating circuit;
The ring tone that occurs between the time set in the time setting register and the second time setting register, and the time set in the first time setting register between the time set in the second time setting register and the time set in the first time setting register. The volume of the generated ringtone can be changed, and the volume of the ringtone at night can be made smaller than during the daytime, depending on the set time.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Second
The figure is a block diagram of a ring tone generating device built into a telephone according to an embodiment of the present invention.

In FIG. 2, 3 is an oscillator, 4 is a timer that generates the time based on the pulses of the oscillator, 5 is a time setting register A that sets the time to change the ring tone, and 6 is the time to set the ring tone back to its original state. The setting register B, 7 is a switch that selects either the output of the timer 4 or the time set in the time setting register A6 or the time setting register B6 and outputs it to the time display section 8, and 8 is the output of the switch 7. 9 is a comparator A that detects a match between the value of the timer 4 and the value of the time setting register A5. 10 is a comparator that detects a match between the value of the timer 4 and the value of the time setting register B6. 11 is a Norinob flop that is set by the output of the comparator A9 and reset by the output of the comparator B1, 12 is a receiving device, and 13 is a Norinob flop that receives the signal output from the receiving device. The selectors 14 and 15 that distribute calls based on control are a ringing tone generating circuit A and a ringing tone generating circuit B connected to the selector 13, respectively.

The operation of the ring tone generating device built into the telephone of this embodiment configured as described above will be explained.

Based on the pulses from the oscillator 3, the timer 4 outputs a 24-hour time, which passes through the spin chia and displays the current time on the time display section 8. This time is the time setting register A
6, the output of flip-flop 11 is +10I+, and in this case selector 1
3 selects the ringing tone generating circuit A14. Therefore, if the receiving device 12 of the telephone in question receives the communication at this point, a ringing tone is generated by the ringing tone generating circuit A14. Next, when the time of the timer 4 matches the time set in the time setting register A5, the comparator A9 sets the flip-flop to "1". As a result, the selector 13 selects the ringing tone generation circuit B16. Therefore, if the receiving device 12 of the telephone in question receives the communication at this point, a ringing tone is generated by the ringing tone generating circuit B15. Furthermore, when the time of the timer 4 advances and the time matches the time set in the time setting register B6, the comparator B1o resets the flip-flop 11, and its output becomes "○" and the ringing tone generating circuit A14 is selected again. 0 In this embodiment, for example, the ringing tone generating circuit A14 generates a loud ringing tone, and the ringing tone generating circuit B15
For example, set the time setting register A5 to 22:0 to generate a relatively low ringtone at
If 0 is set and 7:00 is set in the time setting register B6, a relatively loud ringing sound will be generated by the ringing sound generation circuit A14 from time 7:00 to 22200, and a relatively loud ringing sound will be generated from time 22:o○. to 7=00, a relatively low ringing tone is generated by the ringing tone generating circuit B15.

By selecting the timer switch 7, the time set in the timer 4 indicating the current time, the time setting register A6, or the time setting register B6 is set to 1. It can be displayed on the engraving display section 5.

As described above, according to this embodiment, the timer 49 time setting time setting register A5. Register B6. Comparators A and B (9
, 10), a flip-flop 11° selector 13 and a different ringing tone generating circuit A.

By providing B(14, 16), the volume can be adjusted according to the time.

Note that a part of the configuration of this embodiment can be easily realized using a one-chip microprocessor with a built-in timer.
