Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device.

[0002]

2. Description of the Related Art A cordless telephone system is composed of a fixed machine connected to a telephone line called a base station and a mobile station called a handset. Most of the mobile stations are shown in FIG. The dial input is usually near the earpiece.

In such a structure, when the user of the mobile device tries to make a call, the mobile device is moved away from the face,
Enter the other party's telephone number while looking at the dial input section.
In other words, when the dial input is performed, the receiving speaker is far from the ear, and therefore the dial tone (dialing tone) that prompts the dial input is hard to hear. Therefore, if you try to dial after listening to the dial tone, press the call start button, move the mobile unit close to your face, put the earpiece speaker on your ear to confirm that you can hear the dial tone, and then try again. You must take the action of dialing with the mobile device away from your face.

Therefore, in order to avoid such annoyance, in the conventional cordless telephone device, the LE is installed in the mobile device.
Attach D, and at the same time as pressing the call start button, LE
There is a method for making a dial input guide by blinking D and turning on the LED when the connection of the call channel with the fixed machine is completed.

[0005]

However, in the above-mentioned conventional example, since the dial tone which is the guideline for the original dial input is not heard after the dial tone is heard, the first dial may be missing and the wrong dial may be made. There is a drawback that it is easy to cause.

Further, as with the dial tone, it is difficult to hear the sound (dial pulse, PB sound, etc.) when the cordless telephone device sends the dial to the station, so that the dial is actually sent to the user of the mobile device. It is difficult to confirm whether or not it has been hit.

Furthermore, since the dial input is urged by the LED, the person who used the ordinary telephone, that is,
The person who inputs the dial after hearing the dial tone feels strange and is difficult to use.

The same problem also occurs with a corded one-piece phone in which the handset is provided with a dial input section.

According to the present invention, when a mobile device of a cordless telephone or the like is used, a key operation can be performed while listening to a tone from a receiving speaker, similarly to the case of using a normal telephone. The purpose is to provide.

[0010]

According to the present invention, a telephone device is provided with a detecting means for detecting a tone and a volume adjusting means for adjusting the volume of a receiving speaker by detecting the tone. By increasing the speaker volume and decreasing the volume of the receiving speaker when a tone is detected from the telephone line, when using a cordless phone, etc., the tone from the receiving speaker is used when dialing, just like using a normal telephone. You can operate the keys while listening to, and at the time of a call, you can make a call with just the right volume by putting the receiving speaker on your ear.

1 is a block diagram showing a mobile device 101 of a cordless telephone device according to a first embodiment of the present invention.

The mobile device 101 has an antenna 102 for transmitting and receiving radio signals to and from a fixed device (not shown), a radio circuit section 103 for processing radio signals, and a voice processing circuit 104 for performing voice processing on the transmission and reception signals. A modem 105 that modulates / demodulates transmission / reception signals; a control unit 106 that controls the entire mobile device 101; and an RO that stores a control program.
M107, a tone detection unit 108 that detects a dial or ringback tone from a station (not shown), a selector 109 that selects resistors R1 to R4 according to a control signal from the control unit 106, a transmitter 110, and a receiver 111.
A speaker amplifier 112 for adjusting the output to the handset 111, a call start button 113, and a call end button 114.
And a dial information input unit 115.

Next, FIG. 3 is a flow chart showing the operation of this embodiment.

First, when the user of the mobile unit 101 presses the call start button 113 to make a call (S10).
2) The mobile device 101 establishes a call channel connection with the fixed device (S103).

When the connection of the call channel is completed, the fixed machine issues a call request to the station. For example, when the telephone line connected to the fixed machine is a general analog line, a station line loop is formed.

On the other hand, the station that received the call request sends a dial tone to the terminal to notify that it is waiting for dial input. This dial tone
It is transmitted to the mobile device 101 via the fixed device, and is detected by the tone detection unit 108 via the wireless circuit unit 103 and the voice processing circuit 104 (S104).

The tone detector 108 which has detected the dial tone notifies the controller 106 of the dial tone detection. Upon receiving the notification of dial tone detection, the control unit 106 outputs to the selector 109 a select signal for selecting a resistance value such that the amplification degree of the speaker amplifier 112 is larger than the normal amplification degree.

Here, the normal amplification is the handset 111.
The amplification level is such that the volume is appropriate for listening to the contents of a call by touching. After the dial tone is detected in S104, the resistance value is selected by the selector 109 so that the content of the call can be heard even if the ear is separated from the handset 111 by about 30 cm (S105).

After confirming the dial tone whose volume has thus been raised, the user of the mobile unit 101 thereafter inputs the dial of the other party from the dial information input section 115 (S106), and inputs this dial information. The detected control unit 106 sends dial information to the station through the modem 105, the voice processing circuit 104, the wireless circuit 103, and the antenna 102 (S107).

Upon receiving all the dial information, the station calls the other party if the other party can call and sends a ringback tone to the originating side. The ringback tone is transmitted to the mobile device 101 via the fixed device, passes through the wireless circuit 103 and the voice processing circuit 104, and is detected by the tone detection unit 108 (S108).

The tone detector 108 that has detected the ringback tone notifies the controller 106 of the ringback tone detection. Upon receiving the notification of ringback tone detection, the control unit 106 outputs to the selector 109 a select signal for selecting a resistance value such that the amplification degree of the speaker amplifier 112 becomes the normal amplification degree.

As a result, after the ringback tone is detected,
The volume is appropriate for listening to the call contents by putting the handset 111 on the ear (S109).

As described above, in the present embodiment, when a call is made from the mobile unit 101 of the cordless telephone device, the volume of the handset 111 is audible between the reception of the dial tone and the reception of the ringback tone. Handset 111 to 3
The volume is set so that you can listen to the contents of the call even if it is separated by about 0 cm. Therefore, even if you do not touch the ear with the earpiece speaker, you can hear the dial tone or sound when dialing (PB, PB). Sound etc.) can be heard. Further, since the volume becomes normal after receiving the ringback tone, it is possible to avoid that the volume is too high even if the handset 111 is brought close to the ear in order to talk with the other party after dial input.

Furthermore, it is not necessary to use a display means for notifying the mobile device 101 that dial information can be input, and since the notification that dial information can be input is a dial tone rather than a display means such as an LED, it is a general telephone. It has the advantage that it is easy for users who are familiar with to understand.

FIG. 4 is a flow chart for explaining the second embodiment of the present invention.

In the first embodiment, the dial tone from the station is detected to adjust the reception volume, but in the second embodiment, the reception volume is adjusted based on the depression of the call start button 113. ..

That is, the user of the mobile device 101 presses the call start button 113 to make a call (S20
2) After the mobile device 101 establishes a call channel connection with the fixed device (S203), the control unit 106 selects the selector 1
09, a select signal for increasing the amplification degree of the speaker amplifier 112 than usual is output.

As a result, after pressing the call start button 113, the volume of the call becomes audible even if the ear is separated from the handset 111 by about 30 cm (S205).

According to the second embodiment, the same effect as that of the first embodiment can be obtained. Further, in the first embodiment, since the receiving volume is adjusted by the dial tone, the fixed machine is set to P.
When the dial tone is varied when connecting to a BX or the like, the earpiece volume may not be adjusted, but in the second embodiment, the earpiece volume is adjusted by pressing the call start button 113. Therefore, at the time of making a call, the listening volume becomes an appropriate volume so that the content of the call can be heard even if the ear is separated from the handset 111 by about 30 cm.

Next, in the first embodiment described above, the reception volume is set to the normal volume by detecting the ringback tone, but in the third embodiment, the control unit 106 detects the pressing of the end button 114. In this case, the reception volume may be set to the normal volume. The operation in which the selector 109 selects the resistance value and adjusts the amplification degree of the speaker amplifier 112 according to the select signal of the control unit 106 is the same as in the above-described embodiment.

According to the third embodiment, even when the user presses the end call button 114 and disconnects the call channel before detecting the ringback tone with the above-mentioned listening volume being increased. The volume of the handset 111 can be set to a normal value. Therefore, in particular, when an incoming call is made immediately after pressing the end call button 114 to disconnect the call channel, when the call start button 113 is pressed to respond and the handset 111 is brought close to the ear, the problem that the sound is too loud is avoided. can do.

Next, as a fourth embodiment, the receiving volume may be set to the normal volume when a busy tone is received from the station because the other party is busy during the above-mentioned transmission.

More specifically, when the station receives all dial information from the mobile unit 101 and the other party is busy, it sends a busy tone to the calling side. This busy tone is transmitted to the mobile device 101 via the fixed device, and the wireless circuit unit 10
3 and the voice processing circuit 104, the tone detection unit 10
8 and the control unit 106 is notified.

As a result, the control unit 106 controls the selector 109 by the select signal, and the speaker amplifier 112.
By adjusting the amplification degree of, the reception volume is controlled to be a normal volume.

According to the fourth embodiment, even if the station returns a busy tone instead of a ring back tone after the dial transmission, the reception volume is switched to the normal volume, which is the same as in the first and second embodiments. The effect is obtained.

Although the embodiment of the cordless telephone device has been described above, the present invention is not limited to a cordless phone, but can be similarly applied to a corded one-piece phone in which a dial input section is provided in a handset.

[0037]

As described above, the function of adjusting the volume of the receiving speaker based on the detection of the tone is provided in the mobile device of the cordless telephone or the handset having the dial input section of the corded one-piece phone, thereby providing the user with the function. When making a call, you can check the dial tone, etc. without bringing the mobile device or handset close to your face and putting the receiving speaker on your ear, and bring the handset close to your ear to make a call after dialing. However, it is possible to listen at an appropriate volume without the volume being too loud.

Further, it is not necessary to use a display means for notifying the mobile device that dial information can be input. Since the dial information input notification is not a display means such as an LED but a dial tone, a general telephone can be used. It is easy to understand even for users who are accustomed to.
