Abstract

PURPOSE:To sense an opponent response with an always constant magnitude of a voice even when the voice of an opponent is smaller by providing a means to detect automatically it when the opponent responds, driving a voice signal generating circuit provided separately by the output of the detecting means and informing with the output that the opponent responds. CONSTITUTION:When an opponent picks up a handset and responds, the polarity of a voltage transmitted from a central telephone exchange to a trunk line circuit is inverted, and therefore, this is detected by a polarity inverting detecting circuit 6. When the polarity inverting detecting circuit 6 detects the polarity inversion, it is transmitted through a main control unit 5 to a control unit 15 in a key telephone system 2. When a control unit 15 receives the information of the polarity inversion, a control unit 15 transmits a necessary signal to a voice signal generating circuit 13 with it and the operation is executed so that the necessary voice signal can be outputted from the voice signal generating circuit 13. For that reason, in this condition, the necessary voice signal is outputted from the voice signal generating circuit 13. Thus, regardless of the voice signal from an opponent, the voice of the necessary size is outputted from a speaker 11.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a telephone with a so-called on-hook dialing function, which allows dialing directly without leaving the handset.

BACKGROUND TECHNOLOGY Telephones with on-hook dialing functions are generally known, but all of these types of telephones operate a separately provided monitor push button, capture the central office line, and then operate the dial push button. Diamond 2 You can make a single call, and when the other party answers, the other party's voice will be emitted directly from the speaker.

Problems to be Solved by the Invention Therefore, even with this type of conventional telephone, it is possible to know when the other party answers by the other party's voice, and then it is possible to pick up the handset and talk to the other party. However, this type of device only detects the other party's response based on the other party's voice, and the delay in lifting the hand can cause discomfort to the other party. This was extremely inconvenient, as the voice of the other party was very different from the other, and if it was low, it was very difficult to hear, and sometimes Kokichi did not notice that the other person was responding.

The present invention eliminates the above-mentioned conventional drawbacks, and provides a telephone with an excellent on-hook dialing function that can always accurately and quickly detect the caller's response regardless of line conditions with a simple configuration. − is intended to provide;

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides means for detecting when the other party responds, and the output of the detecting means drives a separately provided audio signal generator. The system is configured so that a speaker notifies that the other party has responded based on the output of the signal generator.

Therefore, according to the present invention, even if the voice signal from the other party becomes very small due to line conditions, a sufficiently large signal can be obtained from the output from the separately provided voice signal generator regardless of this. It has the effect of allowing Kokichi to quickly and accurately sense the opponent's response.

The embodiment diagram is a schematic configuration diagram of an embodiment of a telephone according to the present invention. In the figure, 1 is a main device, and 2 is a button telephone. Reference numeral 3 denotes a central office line circuit constituting the main device, which has a dial signal generation function, an incoming call detection function, and the like. Reference numeral 4 denotes a telephone circuit that also constitutes the main device 1 and has functions such as supplying power to the button telephone 2 and transmitting and receiving data and communication signals. 5 is a main control device consisting of a microcomputer etc. that controls the office line circuit 3, telephone circuit 4, etc., and 6 is a polarity that detects that the polarity of the voltage entering the office line circuit 3 from the telephone office is reversed when the other party answers. 1 is a reversal detection circuit, 1 is a hook switch that is provided in the button telephone 2 and can be switched on when the handset 8 is lifted, 9 is a communication circuit, 10 is an amplifier circuit, 11 is a speaker, 12 is an audio signal output circuit, 13 is a voice signal 14 is a keyboard; 15 is a control device including a microcomputer for controlling the entire telephone 2;

In the above embodiment, when an incoming call is received on the office line, it is detected by the office line circuit 3 and transmitted to the main controller 5. The main control device 6 thereby controls the telephone circuit 4 and notifies the control device 16 in the key telephone 2 that there is an incoming call on the central office line. The control device 15 in the button telephone 2 receives the above information 5 from the main control device 5.

When it receives the signal, it generates an incoming notification signal and transmits it to the amplifier circuit 1o via the audio signal sending circuit 12. Therefore, as a result, a ring tone is output from the speaker 11, and when the handset 8 is lifted, the hook switch 7
is switched to the upper side in the figure, allowing you to talk to the other party.

To make a dial call, you may lift the handset 8 and operate the dial push button inside the keyboard 14, but without lifting the handset 8, operate the monitor push button inside the keyboard 14, and then You may also operate a dial push button. Now, if a monitor push button is operated, this is detected by the control circuit 15 and transmitted to the main control device 5 in the main device 1. Main control device 5
Then, the station line circuit 3 is controlled by this, and the required station line is acquired. When the central office line circuit 3 captures the central office line and then operates the dial push button, the information is transmitted to the main device 1 in the same way.
The dial signal corresponding to the operation of the push button is transmitted from the office line circuit 3 to the office line, respectively.

Page 6 When the other party picks up the handset and responds, the polarity of the voltage transmitted from the telephone office to the office line circuit is reversed, and this is detected by the polarity reversal detection circuit 6. When the polarity reversal detection circuit 6 detects the polarity reversal, it is transmitted to the control device 16 in the button telephone 2 via the main controller 5. When the control device 15 receives the polarity reversal information, the control device 16 transmits a required signal to the audio signal generation circuit 13 and causes the audio signal generation circuit 13 to operate so as to output a desired audio signal. Therefore, in this state, the audio signal generating circuit 13 outputs a required audio signal, which is applied to the speaker 11 via the audio signal sending circuit 12 and the amplifier circuit 10. Therefore, according to the above-described embodiment, the speaker 11 outputs a sound of the required volume regardless of the audio signal from the other party, and the response of the other party can be known more quickly and accurately.

In particular, this embodiment does not detect the voice signal from the other party, but rather detects the polarity reversal of the voltage from the telephone office and uses this to drive the voice signal generation circuit. This system has the advantage that even if the other party does not actually make a sound, it is possible to know the other party's response immediately after picking up the handset, and it is possible to respond more quickly than in the past.

Effects of the Invention As is clear from the above embodiments, the present invention is provided with a means for automatically detecting when the other party responds, and the output of this detecting means drives a separately provided audio signal generating circuit, and the output thereof is The system is configured to notify that the other party has responded, even if the other party's voice is low.
Even if the other party's voice becomes low due to the line conditions, you can always detect the other party's response by the sound of a constant volume, and even if the other party is responding, you can pick up the hand cent without realizing it. This has the advantage that inconveniences such as being left unattended can be effectively prevented.
