JPH01189261A - Telephone set having voice monitor display - Google Patents

Abstract

PURPOSE:To know that an opponent side has a will to execute a call only monitoring a monitor display in the middle of a call without putting a handset to an ear by adding a receiving voice detecting circuit and a monitor displaying circuit for it to a desk telephone set. CONSTITUTION:From a hook switch 1 to a receiving circuit 6, the same action as an ordinary desk telephone set is executed. In the middle of the call, the hook switch 1 is operated, a sound signal from a call opponent is inputted through a hybrid circuit 5 to the receiving circuit 6, the signal is reproduced here, and it gets into the ear of a calling person as a voice. Here, the sound signal to be reproduced by the receiving circuit 6 is simultaneously inputted to a receiving voice detecting circuit 7, the existence of the voice is detected by monitoring a level, the result is sent to a displaying circuit 8, and it is visually observed by the calling person by means of the display of an LED, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a desk telephone, and more particularly to a telephone that can constantly monitor the presence or absence of the other party's voice during a call.

[Conventional technology]

Conventionally, this type of desk phone has a ringing tone generation circuit.

Dial circuit, sending circuit, receiving circuit, hook switch,
It consisted of a hybrid circuit. Recently, in addition to this, there have been so-called high-performance telephones that have functions such as key telephone function, three-party calling, telephone number registration, and transfer by providing a common control circuit outside the desk telephone.

[Problem that the invention seeks to solve]

With the above-mentioned conventional desk telephone, whether it is a normal telephone or a high-performance telephone, it is impossible to know whether there is a voice on the other end of the line unless you hold the handset to your ear. Therefore, if one party to the call removes the handset from their ear, such as by leaving the area, the other party must keep the handset at their ear in order to know when to resume the call. There is a drawback that it must be done.

[Means for solving problems]

The telephone with voice monitor display of the present invention has means for detecting the presence or absence of received voice reproduced by the receiving circuit in the desk telephone, and means for displaying the detected results in real time for visual inspection.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 shows an embodiment of the invention. This embodiment includes a hook switch 1, a ringing tone generating circuit 2, a dialing circuit 3, a transmitting circuit 4, a hybrid circuit 5, a receiving circuit 6, a receiving voice detecting circuit 7, and a display circuit 8. .

The operation from the hook switch 1 to the answering circuit 6 is the same as that of a normal desk telephone. During a call, the hook switch 1 is operated, and an audio signal from the other party is inputted to the receiver circuit 6 via the hybrid circuit 5, where it is reproduced and reaches the ear of the caller as sound. Here, the receiver circuit 6
At the same time, the audio signal to be reproduced is input to the received voice detection circuit 7, the level is monitored to detect the presence or absence of voice, and the result is sent to the display circuit 8 to display the caller on an LED or other display. be visible.

〔Effect of the invention〕

As explained above, the present invention adds an incoming voice detection circuit and its monitor display circuit to a conventional desk telephone, so that it is possible to monitor the monitor display during a call without having to place your ear on the handset. This has the effect of letting you know that the other party is willing to make a call. This is useful when waiting for the other party to answer a telephone call, or when interrupting a call and waiting for it to resume.
