Description

[Detailed Description of the Invention] Industrial Field of Application The present invention uses a remote control to control incoming call response, outgoing calls, dial operations, volume adjustment for sending and receiving, switching characteristics for sending and receiving calls, etc., and to make calls without using a handset. Regarding a hands-free telephone with a remote control.

BACKGROUND OF THE INVENTION Conventional telephones include hands-free telephones that allow telephone calls to be made without the use of a handset, and cordless telephones that connect the telephone body and handset using a wireless signal so that calls can be made remotely from the telephone body.

Problems to be Solved by the Invention However, the above-mentioned conventional hands-free telephone does not have a remote control function, so even though it is hands-free, all operations such as answering incoming calls, making calls, dialing, adjusting volume for sending and receiving, etc. are performed from the telephone itself. There was a problem that it had to be done.

In addition, cordless telephones have separate telephone bodies, handsets, and controls, and although they offer some freedom in terms of space, they do have the problem of having to hold the handset to your ear and mouth just like a regular telephone. there were.

The present invention solves these conventional problems,
The purpose is to provide a hands-free telephone that can remotely control all functions of the telephone.

Means for Solving the Problems In order to achieve the above object, the present invention provides a remote control operation unit having operation buttons and signal transmission means for realizing all functions of a telephone, and a signal reception means for receiving the control signal. Incoming call response, outgoing call, based on the output signal of
The telephone main body includes a main control means for controlling dial operations, volume of transmission/reception, switching characteristics of transmission/reception, and the like.

Therefore, according to the present invention, by dialing or answering an incoming call using the remote control operation unit, the user enters a call state, listens to the other party's voice through the speaker on the phone, and receives his or her own voice through the microphone on the phone. By doing so, you can make hands-free calls.

At this time, you can control the volume of the other party's voice and your own voice using the remote controller.
This has the effect that it is possible to control whether to give priority to transmission or reception, depending on the characteristics of switching between transmission and reception, which is an important feature of a hands-free telephone, that is, depending on the surrounding noise and the volume of the other party's voice.

Embodiment The drawings show the configuration of an embodiment of the present invention. In the figure, 11 is a signal receiving means for receiving a control signal, 12
is a main control means that receives the output of the signal receiving means 11 and actually controls the operation of the telephone, and a hands-free control means 13
, the office line interface means i4, and the communication path switching means 16 for switching between hands-free communication and telephone communication using a handset.

16 is a listening volume adjusting means; 17 is a transmitting volume adjusting means; 1
8 is a speaker connected to the output side of the receiving volume adjustment means 16, 19 is a microphone connected to the input side of the transmission volume adjustment means 170, 20 is a handset, 21 is a 2-wire to 4-wire conversion means, and 22 is an operation. These buttons constitute the telephone main body 1-1.

Further, 23 is an operation button, 24 is a remote control control means to which the operation button 23 is connected, and 26 is a remote control control means 24.
It is a signal transmitting means connected to and transmits a control signal, and these constitute a remote control operation section 1-2.

Next, the operation of the above embodiment will be explained. In the above embodiment, when the operation button 23 of the remote control operation section 1-2 is operated, a control signal corresponding to the operation button is transmitted via the remote control control means 24 to the signal transmission means 26, such as a high frequency signal, an ultrasonic signal, or an infrared signal. Send using one of the following methods.

The signal receiving means 11 of the telephone body 1-2 which has received the control signal activates the main control means 12.
2, the hands-free control means 13, the office line interface means 14, and the communication path switching means 16 are controlled to establish a telephone conversation state.

In this call state, the received voice input from the office line is transmitted to the office line interface means 14 and the communication path switching means 15.
, is listened to through the speaker 18 via the reception volume adjustment means 16.

Further, the transmitted voice is converted into an electrical signal by the microphone 19, and outputted to the central office line via the transmitting sound volume adjusting means 171, the communication path switching means 16, and the central office line interface means 14.

During the above-mentioned call, the receiving volume, the transmitting volume, and the transmitting/receiving switching characteristics are adjusted by the main control means 12 and the hands-free control means by the output of the signal receiving means 11 that receives the control signal from the remote control/operation unit 1-2. This is done via 13.

On the other hand, when the user does not want to make a hands-free call to maintain privacy, the handset 20 is used to make a call. At this time, the main control means 12 controls the communication path switching means 16 to switch the communication path to the transmitter/receiver side.

In addition, the telephone main body 1 can be operated without using the remote control operation section 1-2.
-1, operate the operation button 22 provided on the telephone main body 1-1.
An input signal is input to the main control section 12 to perform call control.

Effects of the Invention As is clear from the above embodiments, the present invention is a hands-free telephone equipped with a remote control function, and the remote control operation allows hands-free calls, that is, calls without placing the handset between the mouth and ear. In addition to being able to talk on the phone while doing other work, it is also possible to adjust the transmitting/receiving volume and adjusting the transmitting/receiving switching characteristics during the call.
It has the effect that various dial operations, incoming call responses, etc. can be controlled simply and easily by remote control operation.
