Abstract

PURPOSE:To discriminate by hearing plural telephone sets by making a possessor of the telephone set arrangeable for its ring tone to a desired ring tone freely. CONSTITUTION:The set ring tone is stored in a memory 10 by providing ring tone information representing loudness and length of a tone to an input means 6, reading the ring tone information at each prescribed time by means of the firmware of a microprocessor 5, and storing as it is or after being converted into a data of the loudness of the inputted tone and inputted time, or in other ways. The ring tone information corresponding to the tone is transmitted simultaneously to a sound source unit 11. The sound source unit 11 converts the ring tone information into an electric signal of the ring tone, transmits it to a sounder 3, and the data is inputted sequentially and stored while monitoring the data as sound.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tone ringer system for telephones and the like.

As shown in Fig. 1, this conventional method is composed of a calling signal detection circuit 1, a toe/ga circuit 2 consisting of a simple LC oscillation circuit, etc., and an electric phonetic transducer 3 such as a sounder. has been done. A ringing signal (incoming call signal) input to the office line connection terminal 4 is detected by the ringing signal detection circuit 1, and the tone ringer circuit 2f is activated to generate a tone ringer sound (hereinafter referred to as ringing sound) signal, and the signal is electroacoustic. The converter 3 generates the ring tone.

However, the conventional tone ringer circuit 2 has fixed circuit element constants, and is limited to one type of ring tone. Therefore, (1) it is not possible to output a ring tone according to the user's preference, and (2) if multiple identical telephones are installed in the same room, it is possible to identify which telephone is being called. It had some drawbacks, such as being stiff.

The present invention provides a tone ringer system in which a desired ring tone can be set in order to solve the conventional drawbacks.

The present invention will be explained in detail below.

FIG. 2 shows an embodiment of the present invention, and the same numbers as in FIG. 1 indicate similar circuits. In this embodiment, 5 is a microprocessor, 6 is an input means, 7a r 7b is a microprocessor, an input port of 5 is, 8 is a microprocessor, an output port of 5 is, 9 is a central processing unit of the microprocessor 5, and 10 is a microprocessor. The memory of the microprocessor 5, 11 a sound source unit, and 12 a telephone circuit. In this embodiment, all operations are implemented in firmware under software control in the microprocessor 5. The operation will be explained below.

The tone ringer sound (ringing tone) enters the setting mode by reading the setting mode into the microprocessor 5 by the firmware via the input port a by the input means 6. For example, the ring tone can be set using the input means 6.
Set ring tone information that indicates the pitch and length of the sound. For this setting, a plurality of input means for specifying the pitch of the sound are provided, and the firmware of the microprocessor 5 reads the ring tone information from the input means 6 at regular intervals, and one of them or manually input the ring tone information. Memo IJ by converting into data of sound pitch and input time, etc.
At the same time, ring tone information corresponding to the tone is sent to the sound source unit 11 from the output terminal 8. The sound source unit 11 converts the ringing tone information into a ringing tone electrical signal, sends it to the sounder 3, and can sequentially input and store data while monitoring the sound. When input of all data is completed, the above operation can be ended by inputting a command to end the setting mode from the input means 6.

Generally, by selecting the constituent frequencies of the desired ring tone and at least one unit length of the duration or pause of the constituent frequencies (or including changing the frequency of the constituent frequencies) within a preset range. By programming the ringtone, the ringtone information described above can be set.

Next, the operation when there is an incoming call and the ring tone sounds will be explained. When a calling signal is input from the office line connection terminal 4,
The calling signal detection circuit 1 detects the calling signal and inputs it to the input port b. When the microprocessor 5 detects the signal using the firmware, it reads the ringing tone information data already stored in the memory 10 as described above, and sends the ringing tone information data to the sound source unit 11 at the output port 8. Output via . The settings for the sound source unit 11 of the ring tone information data have already been set in the memory 10.
If the data stored in the internal memory is data for a certain period of time, set it to the sound source unit 11 at a certain period of time,
If the data is stored as pitch and time data,
Data for the pitch of the corresponding sound may be output to the sound source unit 11, time may be counted by firmware, and human data may be set after the time has elapsed. In this way, the ring tone continues to sound, but the condition for stopping the ring tone is that the ring tone is not detected after a certain period of time has elapsed from the central office line terminal 4, or when the hook switch in the telephone circuit 12 is activated. The on-hook signal is detected by the microprocessor 5 via the input port door b. Therefore,
The ringing tone continues to sound while the ringing signal is being sent, and the ringing tone is stopped when the ringing tone stops coming or off-hook is detected.

6- Also, in another embodiment shown in FIG. 3, the sound source unit) 1
1 is designed to reduce costs by being configured to be used in common with a multi-frequency signal generator for dialing signals of a telephone, and the switching means 13 is normally on the telephone circuit 12 side, so that it can be used for normal dialing operations. Sometimes, by pressing a button on the telephone circuit 12, the signal passes through the switching means 13,
A dial signal is generated by the sound source unit 11, and the signal is sent to the telephone circuit 2 through the switching means 13. The signal is sent from the telephone circuit 12 to the telephone terminal 4, and the dial signal is sent to the central office line. On the other hand, when a calling signal is received from the office line and detected by the calling signal detection circuit 1, its output is input to the microprocessor 5 through the input capo 7a. The microprocessor 5 switches the switching means 13 to switch the sound source unit llf to the microprocessor 5 side. Thereafter, the same operation as in the previous embodiment is performed, so the explanation will be omitted. In this embodiment, the dial signal button and tone ringer setting button are explained separately, but it goes without saying that the same button may be used.

As explained above, according to the present invention, not only can a telephone user freely create a ring tone and use a sound that each individual prefers, but even if multiple telephones are placed in one place. It has the advantage of being easy to distinguish.
