Abstract

PURPOSE:To prevent a sound recording message from being erased erroneously, by executing a judgement of sound recording or reproduction by an output signal from a voice recording/reproducing key and an output signal from a lamp lighting control part, and outputting a control signal to a voice sound recording/reproducing part. CONSTITUTION:When a name of the other party to be messaged is selected from a message destination display part 4, and a voice recording/reproducing key 5 placed on its left side is depressed, a voice recording display lamp 6 is lighted through a lamp lighting control part 12 by its output signal, and simultaneously, by an output from the lamp lighting control part 12, a voice recording/reproducing deciding part 13 outputs a voice recording deciding output to a voice recording/reproducing part 7. When a user confirms lighting and speaks to a microphone 2, an inputted voice signal is recorded in the voice recording/reproducing part 7, and when voice recording is ended, the voice recording display lamp 6 changes to a flickering state. In the case of reproduction, when a person to be messaged recognizes a fact that there is a message to himself by flickering of the voice recording display lamp 6, and depressed the voice recording/reproducing key 5, a voice is outputted from a loudspeaker 3, and the voice recording display lamp changes from a flickering state to a turn-off state.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a voice recording and reproducing device used at home.

2. Prior Art Conventional audio recording and reproducing devices generally use magnetic tape as the recording medium.The audio is received by a microphone, and the analog signal output is recorded directly on the magnetic tape for playback. When the analog signal is
What is received by the playback head is converted into audio by the speaker.

Also, recently, recording and reproducing devices using semiconductor memory as a recording medium have been on the market. During recording, an analog signal received by a microphone is converted into a digital signal by an A/D converter, and then the audio data is recorded in a semiconductor memory. During playback, the audio data recorded in the semiconductor memory is transferred to a D/D converter. The A converter converts the signal into an analog signal, which is then reproduced as audio through a speaker.

Problems to be Solved by the Invention However, such conventional voice recording and playback devices do not have the function of transmitting messages from person to person, and even though they have recorded messages, they may accidentally There was a risk that the previous message would be erased by recording from above.

The present invention solves these conventional problems,
The object of the present invention is to provide a device that prevents recorded messages from being erased by mistake.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a voice recording and playback unit, a recording and playback determination unit, a microphone for voice input, a speaker for voice output, and a plurality of recording and playback units. A home message device is constituted by a key, a recording display lamp that displays each recording status, and a lamp lighting control unit that controls lighting of the recording display lamp, and the recording and playback determining unit is configured to control the recording and playback from the recording and playback key. Recording or playback is determined based on the output signal from the lamp lighting control section and the output signal from the lamp lighting control section, and a control signal is output to the audio recording and playback section.

Operation The present invention has a function of transmitting auditory information from a specific person to a specific person, and is configured so that a single recording and playback key is used for recording and playback operations. There is no risk of accidentally recording another message over the previous recorded message and erasing the previous recorded message.

Embodiment FIG. 1 is an external configuration diagram showing an embodiment of the present invention. In Fig. 1, 1 is the main body of the message device, 2 is the microphone for voice input, 3 is the speaker for voice output, and 4 is the message destination (
5 is a recording/playback key for recording or playing back a message to a specific person;
is a recording display lamp that indicates whether recording has been accepted and whether there is a recorded message.

FIG. 2 is a block diagram showing the internal configuration.

In FIG. 2, 2 shows an audio recording/reproducing unit 7 with a built-in semiconductor memory element, 8 an amplifier that amplifies the input signal from the microphone 2, and 9 an A/D converter that converts the analog signal from the amplifier 8 into a digital signal. The converter 1o is a D/D converter that converts the digital signal from the audio recording/playback section 7 into an analog signal.
A converter, 11 is an amplifier that amplifies the signal from the D/A converter 10, 12 is a lamp lighting control unit that controls lighting of the recording indicator lamp 6 using the output signal from the audio recording and playback unit 7;
13 is the output of the recording/playback key 6 and the lamp lighting control section 12
This is a recording/playback determining unit that determines recording or playback based on the output of the audio recording/playback unit 7 and outputs a control signal to the audio recording/playback unit 7.

The operation in the above configuration will be explained. First, to describe the case of recording, select the name of the person to whom you wish to send a message from the message destination display section 4, and press the recording/playback key 6 on the left side. Then, the recording display lamp 6 is turned on by the output signal of the recording/playback key 6 via the lamp lighting control section 12 . At the same time, the recording/playback determining section 13 outputs a recording determination output to the audio recording/playing section 7 based on the output from the lamp lighting control section 12 . The user recognizes that the recording state is in progress by checking the lighting, and speaks into the microphone 2. The audio signal input from the microphone 2 is amplified by the amplifier 8, converted into a digital signal by the A/D converter 9, and recorded in the semiconductor memory element of the audio recording/playback section 7. When the recording is completed, a recording end signal from the audio recording and reproducing section 7 causes the recording display lamps to change from a lit state to a blinking state via a lamp lighting control section 12. In the case of playback, the message recipient recognizes that he/she has a message by the flashing of the recording display lamp 6 and presses the recording/playback key 5.

Then, the output of the recording/playback key 5 and the lamp lighting control section 12
Based on the output, the recording/playback judgment unit 13 outputs a playback judgment output to the audio recording/playback unit 7. The audio signal recorded in the semiconductor memory element of the audio recording/playback section 7 by this output signal is D
/A is converted into an analog signal via the converter 10, amplified via the amplifier 11, and outputted as audio by the speaker 3. When the reproduction is finished, the recording indicator lamp 6 changes from a blinking state to an extinguished state via the lamp lighting control section 12 in response to a reproduction end signal from the audio recording and reproducing section 7.

Effects of the Invention As described above, according to the present invention, it is possible to easily send a message to a specific person in the home who is not face to face with a simple configuration, and a single recording and playback key is used for recording and playback operations. Since it is configured to be operated using keys, there is no risk of accidentally recording another message over the previous one and erasing the previous recorded message, and it also has the advantage of being configured with a small number of operation keys. , is extremely useful in practice.
