DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ring tone control device for a telephone, which controls the ring tone of various telephones. The present invention relates to a ring tone control device for a telephone to be adjusted.

[0002]

2. Description of the Related Art In a general telephone, the volume of a ringing tone is adjusted by switching a manual switch, and the volume is adjusted so that it can be heard at any place in a house in a normal use state.

In this type of telephone, if the volume of the ringing tone is set low, it becomes difficult to hear when the user is away from the telephone. On the other hand, when the volume is set high, it makes the user feel noisy when there is a person near the telephone.

[0004] In addition, when the telephone is set in a bedroom, if the volume of the ringing tone is increased, the telephone is often woken up at an unexpected time during sleep, and the user often feels uncomfortable.

Therefore, there has been proposed a telephone for automatically adjusting the volume of a ringing tone or activating the answering machine function to solve the above-mentioned problem (Japanese Patent Laid-Open No. 5-2).
No. 2381).

In this telephone, by providing control means for controlling the operation of the volume control means based on the detection outputs of both the human body detection means and the light / dark detection means, it is possible to determine whether or not a person is near and whether the area around the telephone is bright. The configuration is such that both cases of darkness and darkness are combined, and the ringing tone is automatically adjusted to an appropriate volume.

In addition, by providing control means for controlling the volume control means and the answering machine function means based on the detection outputs of both the human body detecting means and the light / dark detection means, the answering machine function may be operated in an appropriate situation. Is what you do.

[0008]

However, although it can be applied to a fixed telephone connected to a telephone line like the above-mentioned conventional telephone, a child device is used separately from a parent device like a cordless telephone. There was a drawback that it was difficult to adopt the model that was used. That is, when applied to a cordless telephone, the human body detection means and the light / dark detection means are installed in a room on the side of the base unit connected to the telephone line.
Since the slave unit is used by moving each room away from the master unit, in order to make the above-mentioned volume control and answering machine function at the time of an incoming call, the two detection means are provided in each room. Must be done.

As described above, providing the detection means in all of the rooms to which the slaves are moved has the disadvantage that the number of installations increases, the construction becomes troublesome, and the economic burden increases.
In addition, a pyroelectric infrared sensor is used for the human body detection means, and the human body detection area is fixed in a ceiling or the like. The problem remains that it cannot be applied to cordless telephones, which are becoming mainstream recently.

The present invention has been made in view of the above-mentioned problems, and is applicable to telephones and cordless telephones connected to an office line, and calls according to the brightness of the place where these telephones are arranged. It is an object of the present invention to provide a telephone ringing tone control device capable of adjusting sound.

[0011]

In order to achieve the above object, the present invention comprises a master unit connected to a telephone line, and the master unit includes a slave unit connected by a wired or wireless line. A ring tone control device for a telephone which emits a ringing tone from the master unit and the slave unit, wherein the brightness detection means provided on each of the master unit and the slave unit for detecting brightness; Volume adjustment means for adjusting the volume of sound, based on a detection signal from the master unit and the slave unit side darkness detection means at the time of an incoming call, both the master unit and the slave unit,
Control means for controlling the sound of the ringing tone from either the master unit or the slave unit, and controlling the volume of the ringing sound by operating the volume adjusting means; and If the surroundings of the base unit are bright based on the determination based on the detection unit, regardless of the determination based on the brightness detection unit on the slave unit, both the base unit and the slave unit have a control mode for emitting a sound at a large volume or a normal volume. A ring tone control device for a telephone set.

[0012]

In this telephone, if a call is received while the user moves the handset away from the base unit, a ringing tone is emitted based on the brightness of the surroundings of the base unit and the handset. It sounds and its volume is automatically adjusted according to the dark state. Then, if the surroundings of the base unit are bright based on the determination based on the brightness detection unit on the master unit side, regardless of the determination based on the brightness detection unit on the slave unit, both the base unit and the slave unit emit sound at a loud volume or a normal volume. If you select the control mode, for example, if the parent device is placed in the living room and the child device is placed at the entrance, even if the living room where there is a person is bright,
In both cases, a ringing tone can be sounded at a high volume or a normal volume, and an incoming call can be transmitted more reliably.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an electrical block diagram showing a ringing tone control device on the base unit side of the cordless telephone according to the present invention, and FIG. 2 is an electrical block diagram showing a ringing tone control unit on the slave unit side.

The cordless telephone has a configuration in which an external call can be made with a terminal telephone and an internal call can be made between a master unit A and a slave unit B connected by a wireless line.

A telephone circuit 2 of a base unit A is connected to a telephone line 1 connected to a telephone exchange (not shown). The telephone circuit 2 performs connection to an outside line, detection of an incoming call, dialing, and the like, and is bidirectionally connected to the master unit control unit 8. The master unit controller 8 is connected to a mode switching circuit 3, a light / dark detection circuit 4, a volume control circuit 5, a transmission / reception circuit 6, and a transmission / reception circuit 7.

The mode switching circuit 3 has a changeover switch 3a for switching between three modes, ON, Auto and OFF. When the changeover switch 3a is set to the ON mode,
Sounds a ringtone when a call arrives. Further, when the mode is changed to the ON mode and then the mode is changed to the Auto mode, the volume of the ringing tone emitted when an incoming call is received is adjusted. Then, when the mode is set to the OFF mode, the base unit control section 8 is operated so as not to emit a ringing tone when an incoming call is received.

The light / dark detection circuit 4 is connected with a Cds 4a as a photo sensor. When the light / dark state of the master unit A is detected by the Cds 4a, a detection signal corresponding to the illuminance is sent to the control unit 8. It has become.

The output of the volume control circuit 5 is connected to a speaker 6b, which will be described later, and adjusts the volume of a ring tone emitted from the speaker 6b based on a control signal from the base unit control section 8. The volume is set in advance so as to have a small volume according to the dark state, but the volume range can be varied as necessary. In addition, the lower the frequency of the ringing tone, the lower the frequency range.

The transmission / reception circuit 6 is connected to a microphone 6a, which is a transmission / reception device, and a speaker 6b. Further, the transmission / reception circuit 7 is connected to an antenna 7a for transmitting / receiving a signal to / from the slave unit B.

The master unit control unit 8 controls the operation of the master unit A as a whole, and detects the brightness of the master unit A and the slave unit B when there is an incoming call in accordance with the selection mode of the mode switching circuit 3. On the basis of the detection signals from the circuits 4 and 12, the master unit A and the slave unit B perform control to emit a ringing tone and adjust the sound volume.

The slave B has an antenna 10a for transmitting and receiving signals to and from the master A, which is connected to the transmission / reception circuit 10. The transmission / reception circuit 10 has a function of transmitting a light / dark detection signal to the master A via the antenna 10a, and is bidirectionally connected to the slave controller 14. The handset control unit 14 includes a transmission / reception circuit 11 and a light / dark detection circuit 1.
2 and the volume control circuit 13 are connected.

The transmission / reception circuit 11 includes a microphone 11a and a speaker 11b. The light / dark detection circuit 12 also includes a Cds 12a similar to that of the master unit A. This Cds1
Reference numeral 2a is provided in the slave unit B main body, and can detect the light / dark state of any place where the slave unit B is moved.

The volume control circuit 13 also has the same function as that of the main unit A, and its output is given to the speaker 11b to control the volume of the ringing tone.

The handset control unit 14 controls the operation of the handset B as a whole, and sends a control signal for volume control to the volume control circuit 13 based on a signal from the base unit A when an incoming call is received. Configuration.

Next, the operation of the ringing tone control device for a telephone will be described with reference to the flowchart of FIG.

However, in this operation, the user has set the changeover switch 3a to the Auto mode, and
Here, a general case in which an incoming call is received when is moved to a place away from the master unit A will be described.

When the telephone circuit 2 detects an incoming call (step S11), an incoming call detection signal is sent to the base unit control section 8. The master unit control unit 8 operates the Cds 4a on the master unit A side (step S12), and sends out a signal for operating the Cds 12a to the slave unit B side via the transmission / reception circuit 7 (step S13).

Along with this, the Cds 4a, 12a on the master unit A side and the slave unit B side detect the light / dark state, and output a detection signal corresponding to the illuminance. Here, the detection signal on the master unit A side is directly sent to the master unit control unit 8, but the slave unit B
The detection signal on the side is sent to the slave unit control unit 14, is modulated by the transmission / reception circuit 10, and then sent to the master unit A side. Then, after being demodulated by the transmission / reception circuit 7 on the master unit A side, it is given to the master unit control unit 8.

First, when a detection signal is sent from the light / dark detection circuit 4 of the master unit A, it is determined whether the periphery of the master unit A is in a bright state (step S14). In the base unit control unit 8, when the surroundings around the base unit A are bright, the volume of the ringing tone is increased and the sound is emitted (step S15). Is emitted (step S16).

Next, when a detection signal is transmitted from the light / dark detection circuit 12 of the slave B, it is determined whether or not the periphery of the slave B is in a bright state (step S17). Based on this result, base unit control section 14 sends a control signal to handset B side, and when the surroundings of handset B side are bright as described above, the volume of the ringing sound is increased and the sound is emitted (step S1). S18) If it is dark, a ringing tone having a small volume according to the darkness is emitted (step S19).

For this reason, when the surroundings of the master unit A and the slave unit B are bright, a ringing tone is emitted at a loud or normal volume in any place, and when one is bright and the other is dark, A ringing tone is emitted at a small volume corresponding to the brightness.

Thereafter, it is determined whether or not the handset of the master unit A or the slave unit B is picked up and goes off-hook (step S20). When the handset goes off-hook, the base unit-side control unit 8 emits a ringing tone. Is stopped (step S
21), the operation of each of the Cds 4a and 12a is also stopped (step S22).

As described above, the ringing tone is automatically adjusted in accordance with the brightness of the room in which the fixed base unit A and the mobile unit B to be moved regardless of the place are placed, so that the mobile unit B can be moved to the bedroom or the like. If you fall asleep while being placed in the room, the ring tone will not hinder sleep.

At this time, when the main unit A is bright, if there is a person near the main unit A, the call can be answered without any trouble. When the state is reversed, the user of the slave unit B can answer the call. Further, the following mode can be added to the mode switching circuit 3 as the fourth mode. That is, if the master unit A is bright, the slave unit B
Regardless of the lightness / darkness state of the side, the master unit A and the slave unit B are caused to emit sound at a large volume or a normal volume. That is, for example, if the main unit A is set in the living room and the sub unit B is set in the entrance, even if the entrance becomes dark at night, if the living room where the person is present is bright, both of them will be loud. You can ring and let someone in your family know about the incoming call.

In the above embodiment, the case where the present invention is applied to a cordless telephone has been described. However, the present invention is also applicable to a parent-child type telephone in which the base unit A and the child unit B are connected by a wired line or a telephone having an intercom function. it can.

It is needless to say that the present invention can be applied to a general-purpose telephone, and in this case, the configuration is substantially the same as that of the master A except that the slave B does not exist.

[0037]

As described above, according to the present invention, at the time of an incoming call, both the master unit and the slave unit, either the master unit or the slave unit based on the brightness of the master unit and the slave unit. In addition to performing control to emit a ringing tone from one side, the volume of the ringing tone is adjusted according to the dark state, so that the user can move the handset away from the base unit in a dark place, such as a bedroom. If there is an incoming call while moving to, the ringtone is emitted on the base unit side, so that it is possible to respond to the call without any trouble,
There is an effect that the sleeping user is not hindered from sleeping by the ringing tone. In addition, if the surroundings of the master unit are bright based on the judgment based on the brightness detection unit on the master unit side, regardless of the judgment based on the brightness detection unit on the slave unit, both the master unit and the slave unit emit sound at a high volume or a normal volume. If the control mode is selected, for example, if the parent device is placed in the living room and the child device is placed at the entrance, if the living room where there is a person is bright, both can ring at a loud volume or normal volume, and the incoming call will be more reliable Can be told.
