Abstract

PURPOSE:To prevent the omission of the head of a voice by transmitting a tone signal from a tone line to a caller side during the radio connection of a connector with a ratio telephone set, at the time of requesting a voice calling to the ratio telephone set. CONSTITUTION:When the request of the voice calling from a certain telephone set to a radio telephone set 3 is detected by a connector 2, the tone signal indicating that the voice calling can not be operated even when the voice is uttered for the radio connection, is transmitted from a tone circuit 22 to the telephone set at the caller side, and the ratio connection is operated by a communication control circuit 23. On the other hand, after the completion of the radio connection, the radio telephone set 3 controls a voice speech line 33, and opens a speech path through a power amplifier 34 to a speaker 35, so that the voice calling state can be attained. Then, the connector 2 stops the tone signal outputted from the tone line 22 at the time of detecting the completion of the radio connection with the radio telephone set 3.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless telephone device which includes a connecting device and a wireless telephone and is capable of making voice calls to the wireless telephone. The system is configured to send a tone to the transmitter during the process of establishing a wireless connection with the transmitter.

0002

[Prior Art] In a conventional cordless telephone device,
When attempting to make a call to a wireless telephone, it takes time to process the wireless connection between the wireless telephone and the connecting device, and the voice call becomes possible after the connection process is completed.

0003

As described above, in the conventional cordless telephone device, even if a voice call is made during the connection process, the voice is not transmitted, so there is a problem that the beginning of the voice is cut off. Further, when making a voice call to a plurality of wireless telephones, the wireless connection status of all the wireless telephones is not known, which causes not only the problem of the end of the call being interrupted, but also the problem of the timing of the tone being shifted.

0004

[Means for Solving the Problems] By providing a tone circuit and a communication control circuit in a connecting device of a cordless telephone device, and providing a power amplifier and a speaker in a wireless telephone device, the wireless telephone device is provided with a power amplifier and a speaker. This system is configured to notify the wireless connection status by sending a tone to the calling side. In addition, a tone circuit is provided in the main device, and a communication control circuit is provided in the connection device, so that when the main device is in the process of wirelessly controlling the voice calling circuit, a tone is sent to the calling side to notify that it is in a wireless connection state. It is composed of

[0005]

[Operation] When the connecting device or the main device detects that a voice call has been made to the wireless telephone, a wireless connection is established between the connecting device and the wireless telephone, and a tone is sounded on the calling side during the connection process. Send a signal. On the transmitting side, this tone signal allows the user to know that no sound is being output from the speaker of the radio telephone even if the user speaks.

【Example】

(First embodiment) As shown in FIG. 1, a main device 1, a telephone connected to the main device 1 by wire, a connecting device 2 connected to the main device 1, and a connecting device It consists of a wireless telephone 3 that is connected wirelessly through the wireless telephone.

The main device 1 includes a microcomputer 11 and a communication circuit 1.
3, and the connection device 2 includes a communication circuit 20, a microcomputer 21 that controls the connection device, a tone circuit 22 that sends a tone to the transmitting side, and a communication control circuit 23. The wireless telephone 3 includes a microcomputer 31 that controls the wireless telephone.
, a communication control circuit 32 , a voice communication circuit 33 , a power amplifier 34 , and a speaker 35 .

When the connection device 2 detects that a voice call has been made from a certain telephone to the radio telephone 3, the tone circuit 22 detects that the telephone on the calling side is currently connected wirelessly and is not making a voice call. A tone signal indicating that a voice call cannot be made even if the voice call is made is sent out, and a wireless connection is established by the communication control circuit 23.

On the other hand, in the wireless telephone 3, when the wireless connection is completed, the voice communication circuit 33 is controlled to open a communication path to the speaker 35 via the power amplifier 34, and enter a voice call state. When the connecting device 2 detects that the wireless connection with the wireless telephone 3 is completed, the tone signal output from the tone circuit 22 is stopped.

[0010] The telephone on the calling side knows that voice calling is now possible when the tone signal stops, so the calling party can make a sound to call the other party.

(Second Embodiment) As shown in FIG. 2, this device differs from the device shown in FIG. 1 in that the main device 1 is provided with a tone circuit 12 and the connection device 2 is not provided with a tone circuit. , the other configurations are almost the same.

When the main device 1 detects that a voice call is being made to the radio telephone 3, the tone circuit 1 of the main device 1 is activated.
2 sends out a tone signal indicating that it is wirelessly connected to the calling side telephone and cannot make a voice call even if it utters a voice, and also sends a command to the microcomputer 21 of the connecting device 2.

The microcomputer 21 of the connection device 2 enters into a wireless connection via the communication control circuit 23.

On the other hand, in the wireless telephone 3, when the wireless connection is completed, the voice communication circuit 33 is controlled to open a communication path leading to the speaker 35 via the power amplifier 34 and enter a voice call state.

When the connecting device 2 detects that the wireless connection with the wireless telephone 3 is completed, the main device 1
send a command to. When the main device receives this command, it stops the tone signal being output from the tone circuit 22.

[0016] Since the telephone on the calling side knows that voice calling is now possible when the tone signal stops, the calling party can make a sound to call the other party.

According to this second embodiment, even if a plurality of cordless telephones are installed and a simultaneous voice call is to be made, all the wireless telephones 3 can be controlled centrally by the main device 1. Tone signals can continue to be sent to the calling party until the connection is completed.

[0018]

【Effect of the invention】

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, when making a voice call to a wireless telephone, during the wireless connection between the connecting device and the wireless telephone, the tone circuit By sending a tone signal to the calling side, it is possible to notify that a wireless connection is in progress and that a voice call cannot be made even if a voice is emitted.

Furthermore, by centrally controlling a plurality of cordless telephones by the main device, it is possible to prevent the beginning of the voice from being cut off even when making a simultaneous voice call.
