JPS63220638A - Telephone set equipped with visual display system - Google Patents

Abstract

PURPOSE:To improve the quality of a telephone set function and to increase the number of telephone set users by making a voice signal into a digital signal when a user operates a switch in a communication line connecting condition, and after this is converted to a visual display signal, displaying it to the visual display system as a character. CONSTITUTION:In a telephone set main body 1, when a switch 3 is depressed in the communicating connecting condition, the same voice signal as that to flow at a receiver 2 enters a digital signal converting circuit 4, is made into a digital signal, thereafter, it is converted to a signal for visual display by a signal converting circuit 5 for visual display, outputted as a character at a visual display system 6, therefore, the call can be confirmed visually.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to telephones with visual indicators.

[Conventional technology]

Conventional telephones of this type can only send and receive voice messages using the transmitter and receiver while connected to a line. Furthermore, the audio output level of the receiver depends on the strength of the audio signal.

[Problem that the invention seeks to solve]

With the conventional telephones mentioned above, communication was possible by recognizing the other party's voice through hearing while the line was connected, but depending on the strength of the voice signal, the voice may be difficult to hear, so please check the content. In order to do so, it took time and effort to ask the other party again. Another disadvantage is that it is difficult to communicate with hearing-impaired people over the phone.

[Means for solving problems]

The telephone of the present invention has a function of converting a voice signal into a digital signal by operating a switch while connected to a communication line, a function of displaying the converted signal on a visual display, and a function of displaying the converted signal on a visual display. According to this function, when the voice signal during a call is weak, the other party's voice signal is digitized by switching between Sui and Sochi and displayed as characters on the visual display.

〔Example〕

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

FIG. 1 is a circuit diagram of an additional function section of a telephone according to an embodiment of the present invention, and the circuit configuration equivalent to that of a conventional telephone is omitted. 1 indicates the main body of the telephone. When the switch 3 is pressed while the communication is connected, the same audio signal flowing to the receiver 2 enters the digital signal conversion circuit 4 and is converted into a digital signal, and then converted into a visual display signal by the visual display signal conversion circuit 5. Since the information is output as characters on the visual display 6, it becomes possible to confirm the call visually.

FIG. 2 is an external perspective view of the telephone with a visual display according to the embodiment shown in FIG. A switch 3 and a visual indicator 6 are attached to the telephone body.

[Effect of invention]

As explained above, the present invention enables a conventional telephone to convert a voice signal into a digital signal when a user operates a switch while connected to a communication line, converts this into a visual display signal, and then displays the signal on a visual display. By displaying the text as text, the conventional method of communicating only by hearing becomes a method of communicating visually, which overturns the conventional concept and has the effect of contributing to improving the quality of telephone functions and increasing the number of telephone users.

[Brief explanation of the drawing]

FIG. 1 is a circuit diagram of an additional function section of a telephone according to an embodiment of the telephone with a visual display according to the present invention, and FIG. 2 is an external perspective view of the telephone with a visual display according to the embodiment shown in FIG. . DESCRIPTION OF SYMBOLS 1... Telephone main body, 2... Receiver, 3... Switch, 4... Digital signal conversion circuit, 5... Signal conversion circuit for visual display, 6... Visual display.

Claims (1)

[Claims] There is a function that converts audio signals into digital signals when the user operates a switch while the communication line is connected, and a function that displays the signals converted to digital signals on a visual display. A telephone with a visual display device, characterized in that when the voice signal is weak, the other party's voice signal is digitized by switching a switch and displayed as characters on the visual display device.
