Abstract

PURPOSE:To prevent reproduced sound from the trouble of horizontal inversion by forming a switching mechanism to be switched in accordance with a sound recording format arranging a sound source in the front of the mechanism or on its back to record sound stereoscopically by a pair of microphones and reproduce the sound by a pair of speakers. CONSTITUTION:The changeover switch mechanism 12 switches a state connecting the left input terminal 13 of a sound recording/reproducing part 5 to the left microphone 1 through an amplifier 4 and connecting the right input terminal 13' of the sound recording/reproducing part 5 to the right microphone 1' through an amplifier 4' and a state connecting the terminal 13 to the microphone 1' through the amplifier 4' and connecting the terminal 13 to the microphone 1 through the amplifier 4. Thus, the mechanism 12 is switched in accordance with the sound recording format arranging the sound source in the front of the mechanism 12 or on its back to output the sound from the speakers 2, 2', so that the reproduced sound can be prevented from the trouble of horizontal inversion.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a recording and reproducing device that performs three-dimensional recording using a pair of microphones and reproducing it using a pair of speakers, and particularly relates to a recording and reproducing device that uses a cassette tape as a tube. The present invention relates to a portable cassette tape recorder which is a portable recording/playback device.

[Conventional technology]

3 and 4 are a front view and a plan view, respectively, of a general integrated portable cassette tape recorder.

Left and right directional audio input microphones 1.1' are provided at the top, and left and right reproduction output speakers 2, 2' and a cassette tape 3 mounting section are provided at the front.

FIG. 2 is a block diagram showing a conventional portable cassette tape recorder, in which audio signals input through microphones 1 and 1' are amplified by amplifiers 4 and 4', and a recording/playback unit 5
is recorded onto cassette tape 3. The audio signals already recorded on the sumo wrestler tape 3 are reproduced by the recording/reproducing section 5 and outputted from the speakers 2, 2'.

In this conventional portable cassette chip recorder, the audio input from the left microphone 1 is output from the left speaker 2, and the audio input from the right microphone 1' is output from the right speaker 2'. It has become.

[Problem that the invention seeks to solve]

With the above-mentioned conventional portable cassette tape recorder, if you record with your head facing the sound source, when you play it back, you will be listening to it while facing the stereo speakers, so the left and right sounds will be distorted. The main output is output again as if it were reversed.

FIG. 5 is a plan view showing the relationship between the conventional portable cassette tape recorder 6 and sound sources 7 to 9 shown in FIG.
The voices of person 9 are input from microphones 1 and 1' respectively, and when recording, person 10 listens to the sounds from sound sources 7 to 9 facing toward each other as schematically shown, but when playing back, , 11, the reproduced sound is generally heard in the direction facing the speaker 2.2' of the tape recorder 6. In this case, when the person 11 hears the reproduced sound from the speakers 2 and 2', the positions of the sound sources 7 to 9 heard by the person 10 are reversed left and right.

The object of the present invention is to provide a recording and playback device that prevents the recording source and playback sound from being played back in reverse, and can play back the sound so that the sounds on the right and left sides of the sound source are output from the same direction. Our goal is to provide the following.

[Means for solving problems]

The recording/playback device of the present invention includes first and second microphones, first and second speakers, and outputs a live signal input from the first microphone and recorded from the second microphone, or The second speaker is configured to play back audio input and recorded from the first microphone.

〔Example〕

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

FIG. 1 is a block diagram of one embodiment of the present invention.

In this embodiment, the changeover switch mechanism 12 connects the left input terminal 13 of the recording/playback section 5 (when the signal from the input terminal 13 is played back after the tsuba sound, it is output from the left speaker 2) to the amplifier 4. is connected to the microphone 1 on the left side through the input terminal 13' on the right side of the recording/playback section 5 (when the signal from the input terminal 13' is played back after recording, it is output from the speaker 2' on the right side). is connected to the right microphone 1' through the amplifier 4', or the left input terminal 13 is connected to the right microphone 1' through the amplifier 4', and the right input terminal is connected to the right microphone 1' through the amplifier 4. You can switch the microphone so that it is connected to the left microphone l. The audio input by microphone 1 is switched to either speaker 2 or 2' and output, and at the same time the audio input by microphone 1' is output to speaker 2' or 2'.
Switch and output from either one.

You can freely select whether or not the right and left sides of the playback sound intersect.

Therefore, depending on the recording format of front recording where the sound source is on the front of the cassette recorder or rear recording where the sound source is on the back of the cassette recorder, the changeover switch mechanism 12 is appropriately switched, and the above-mentioned playback is performed. It is possible to prevent the problem of left/right reversal of sound.

〔Effect of the invention〕

As explained above, the present invention enables reproduction while faithfully maintaining the left-right relationship of the sound source, and has the effect of preventing the problem of reversal of the left-right relationship of the reproduced sound.
