Abstract

PURPOSE:To listen to a signal of high speed reproduction at a normal speed by providing a reproduction speed selection means to select either a reproduction speed the same as the recording speed or a reproduction speed slower than the recording speed and a control means controlling the reproduction speed of the reproduction means based on the selected reproduction speed by the reproduction speed selection means. CONSTITUTION:Suppose that an audio signal reproduced at a speed twice the normal speed is sent via a telephone line 1 when a recording switch 9 is set and a recording section 3 is brought into the recording mode by a control circuit 8. A reproduction section 5 reproduces the audio signal stored in a storage section 4 at the same speed as the recording speed of the recording section 3 and is outputted from a speaker 7 via an amplifier 6. Since the operator hardly listens to the audio signal because of two fast speed, a reproduction switch 10 is opened to turn on a low speed reproduction switch 11. Then the reproduction section 5 reproduces the audio signal stored in the storage section 4 at a speed half the recording speed of the recording section 3 and the resulting signal is outputted from the speaker 7 via the amplifier 6.

Description

[Detailed description of the invention] <Industrial application field> The present invention relates to an answering machine.

<Conventional technology> Conventional answering machines equipped with recording/playback functions record voice signals sent via a telephone line at a fixed recording speed, and then output the recorded voice signals at the same speed as the recording speed. I was trying to play it.

<Problems to be Solved by the Invention> By the way, there are telephone answering machines that record and play f2 content and transfer it to a predetermined party. As shown, some recordings are played back at a faster speed than the recording speed in order to shorten playback time.

When a voice signal that is played back at high speed by such a telephone and sent out to a telephone line is received, recorded, and played back by the above-mentioned conventional answering machine, there is a problem in that the played voice is so fast that it becomes difficult to hear. .

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to be able to receive and record an audio signal that has been reproduced at high speed, to be able to reproduce it at a speed slower than the recording speed, and to listen to the reproduced audio at the normal speed. Our goal is to provide an answering machine that can do this.

Means for Solving the Problems To achieve the above object, the present invention provides a storage means for storing audio signals, and a storage means for storing audio signals sent via a telephone line at a predetermined recording speed. In an answering machine, the answering machine is equipped with a recording means for recording on the recording means, and a reproduction means for reproducing the audio signal recorded on the storage means, a reproduction speed equal to the recording speed and a reproduction speed slower than the recording speed. The present invention is characterized by comprising a playback speed selection means for selecting one of the playback speeds, and a control means for controlling the playback speed of the playback means based on the playback speed selected by the playback speed selection means.

<Operation> The recording means records the audio signal sent via the telephone line into the storage means at a predetermined recording speed, and the reproduction means reproduces the audio signal recorded on the storage means. The operator is
If the playback speed selection means selects a playback speed that is the same as the recording speed, and the reproduced audio is faster than the normal speed and difficult to hear, the playback speed selection means selects a playback speed that is the same as the recording speed. Select a slow playback speed. Then, the control means controls the reproduction speed of the reproduction means based on the selected reproduction speed, and the reproduction means reproduces the audio signal recorded in the storage means at the selected reproduction speed.

Therefore, even if an audio signal that has been played back at high speed is received and recorded, it can be heard at normal speed by playing it back at low speed.

<Example> Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

FIG. 1 is a block diagram showing the circuit configuration of the main part of an embodiment of the present invention.

In FIG. 1, 1 is a telephone line, 2 is a line interface unit that is an interface with the telephone line 1, 3 is a storage unit 4 for storing voice signals sent through the telephone line 1 and the line interface unit 2. This is the recording section for recording. The storage medium used in this storage unit 4 is I
It may be either C or magnetic tape. Reference numeral 5 denotes a playback unit that plays back the audio signal recorded in the storage unit 4, 6 an amplifier that amplifies the audio signal reproduced by the playback $5, 7 a speaker, and 8 the recording unit 3 and the storage unit 4. and a control device that controls the reproduction section 5. Also, 9
10 is a recording switch for setting the recording section 3 to the recording state, and 10 is a playback switch 10 for setting the playback speed of the playback section 5 to the same speed as the recording speed of the recording s3.
IK is a low-speed playback switch for setting the playback speed of the playback section 5 to one half of the recording speed of the recording section 3.

In the above configuration, if the recording switch 9 is currently in the on state and the recording section 3 is in the recording mode by the control device 8, the audio signal reproduced at twice the normal speed or the telephone line It is assumed that the signal is sent via l and is f2. Then, this audio signal is recorded in the recording section 3 or the storage section 4.

Then, when the operator turned on the playback switch lO to listen to the contents recorded in the storage unit 4,
The reproduction section 5 reproduces the audio signal stored in the storage section 4 at the same speed as the recording speed of the recording section 3, and outputs it from the speaker 7 via the amplifier 6. Since this voice is too fast to hear, the operator turns off the playback switch 10 and turns on the low-speed playback switch 11. Then, the reproduction section 5 reproduces the audio signal stored in the storage section 4 at a speed that is half the recording speed of the recording section 3, and outputs it from the speaker 7 via the amplifier 6. This allows the operator to listen to the recorded content at normal speed.

In the above embodiment, the playback speed is set in two stages, but it is also possible to change the playback speed continuously. By doing so, it is possible to respond more flexibly to the speed of the input audio signal.

<Effects of the Invention> As is clear from the above, the answering machine of this invention has the following advantages:
a playback speed selection means for selecting either a playback speed equal to the recording speed of the recording means or a playback speed slower than the recording speed; and a playback speed of the playback means based on the playback speed selected by the playback speed selection means. and a control means for controlling a reproduction speed, the audio signal recorded in the storage means by the recording means can be reproduced by the reproduction means at a speed slower than the recording speed, and therefore the audio signal reproduced at high speed can be reproduced by the reproduction means. Even if you receive or record a message, you can listen to it at normal speed by playing it back at low speed.
