Abstract

PURPOSE:To start and finish sound recording and reproduction automatically by incorporating a voice encoder/decoder and a semiconductor memory in the handset, and providing a hook switch and a control circuit. CONSTITUTION:A control circuit 18 detects the hook switch changing from the on-hook state to the off-hook state and connects a switch 16 to a sound recording side, and also sends a command for the start of the sound recording of a received signal to the voice coder decoder 14 and semiconductor memory 15. The control circuit 18, on the other hand, sends a command for the end of the sound recording to the voice encoder/decoder 14 and semiconductor memory 15 on detecting the hook switch 17 changing from the off-hook state to the on-hook state, and the sound recording of the received signal is finished. For reproduction, the handset is lifted while a push button 24 for reproduction selection switch is pressed, thereby entering the off-hook state. A receiver 11 is connected to only the voice encoder/decoder 14 which is disconnected from a telephone set main body.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application 3 /\-/ The present invention relates to a telephone handset which is a terminal device of a voice communication system.

Conventional technology In recent years, advances in semiconductor technology have led to larger capacity and lower cost semiconductor memories, and telephones with the ability to convert voice into digital signals and store them in memory have come into widespread use. Ta.

A conventional handset will be described below with reference to the drawings.

FIG. 3 shows the configuration of a conventional handset. In FIG. 3, 31 is a receiver for amplifying the received signal, 32 is a transmitter for collecting the transmitted signal, 33 is a handset housing, and 34 is a connector for connecting the telephone main body and the handset.

Regarding the conventional handset configured as above,
The operation will be explained below.

The receiving signal sent from the telephone body is sent to the connector 34.
The voice is amplified by the telephone receiver 31 via the telephone receiver 31. - side, transmitter 32
The voice signal collected is transmitted to the telephone main body as a transmission signal via the connector 34.

Problems to be Solved by the Invention However, in the above-mentioned conventional configuration, the no-docent is simply an interface that connects the sending signal and the receiving signal with the telephone body, and in order to record a call, the telephone body must have a recording/playback function. I had to replace the phone with one that had one. Still, in order to record a call, it is necessary for a person to turn on the recording device, record for the required amount of time, and then stop the recording device, making it difficult to re-check the content of the call after the call ends. In this case, there was a problem in that a person had to perform an operation to start recording during a call.

The present invention solves the above-mentioned conventional problems and provides a handset that can automatically record a call by lifting the handset.

Means for Solving the Problems To achieve this object, the handset of the present invention includes a voice code decoder, a semiconductor memory, a hook switch, and a voice code decoder for recording/playback according to the output signal of the hook switch. The configuration includes a control circuit that performs mode switching and start/stop switching.

Function: With this configuration, the hook switch detects the start and end of a call, and this detection signal allows the start and end of call recording and playback to be automatically performed in a preset procedure.

EXAMPLE An example of the present invention will be described below with reference to the drawings.

FIG. 1 shows the configuration of a handset in one embodiment of the present invention. In FIG. 1, 11 is a receiver for amplifying the received signal, 12 is a transmitter for collecting the transmitted signal;
13 is a connector that connects the handset and the telephone body; 14 is a connector that encodes an analog voice signal into a digital signal;
Alternatively, a voice code decoder 15 decodes a digital signal stored in the semiconductor memory 15 into an analog voice signal, and 15 is a voice code decoder 6.

16 is a semiconductor memory for storing the digital signal encoded by the audio encoder 14;
7 is a hook switch that detects the on-hook or off-hook state of the node, 18 is a hook switch 1
19 is a control circuit for switching the recording and playback modes of the switch 16, the audio code decoder 14 and the semiconductor memory 15, and issuing commands to start and end recording and playback in response to the detection signal 7; 19 is an operation during playback; This is a playback selection switch that performs.

The operation of the node set configured as described above will be explained below. First, the operation during recording will be explained. The control circuit 18 detects that the hook switch 17 has changed from the on-hook state to the off-hook state, connects the switch 16 to the recording side, and switches the audio code decoder 14 to the recording side.
and issues a command to the semiconductor memory 15 to start recording the reception signal. During recording, the switch 16 is connected to the recording side, and the receiving signal sent from the telephone body is connected to the connector 1.
37, the voice code decoder 14 encodes the received voice signal and outputs the digital signal to the semiconductor memory 15.
writes a digital signal to and records the received signal.

On the other hand, when the control circuit 18 detects that the hook switch 17 has changed from the off-hook state to the on-hook state,
A command to end the recording is issued to the voice code decoder 14 and the semiconductor memory 15, and the recording of the received voice signal is ended. By the above operation, the received signal is recorded only when the handset is in the off-hook state. In this case, the transmission signal is recorded as sidetone via the telephone body, and the conversation during the call is recorded.

Next, the case of playing back the recorded content will be explained.

FIG. 2 is a sketch showing the appearance of the handset of this embodiment, in which reference numeral 21 indicates a hook switch button;
2 is a mouthpiece, 23 is an earpiece, 24 is a button for a reproduction selection switch, 25 is a curl cord, and 26 is a connector plug. After the call recording is finished, the handset is on-hook.

When reproducing this content, the handset is picked up while pressing the reproduction selection switch button 24 and placed in an off-hook state. At this time, the control circuit 18 connects the switch 16 to the reproduction side by detecting with the hook switch 17 that the reproduction selection switch 19 is active and that the on-hook state has changed to the off-hook state, and connects the switch 16 to the audio code decoder. 14 and semiconductor memory 15 to reproduce the recorded contents. When playing, switch 1
6 is connected to the reproduction side, and the receiver 11 is connected only to a voice code decoder 14 which is separated from the main body of the telephone. The audio code decoder 14 decodes the digital signal read from the semiconductor memory 15 and converts it into an analog audio signal, which is amplified by the receiver 11. When the control circuit 18 detects that the hook switch 17 has changed from the off-hook state to the on-hook state, the control circuit 18 issues a command to the audio code decoder 14 and the semiconductor memory 15 to end playback, and the playback of the recorded content is stopped. finish. The above operation allows the recorded content to be played back only when the handset is in an off-hook state.

As described above, according to this embodiment, the contents of the call can be recorded in the semiconductor memory 15 provided inside the handset, and the hook switch 17 can also be used to start and end recording and playback.

Effects of the Invention The present invention includes a voice code decoder and a semiconductor memory built into the handset, thereby making it possible to record calls, and furthermore, by providing a hook switch and a control circuit, the handset can be turned on-hook.

Start recording or playback depending on off-hook status.

This realizes an excellent node set that can automatically perform the termination operation.
