Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a tape recorder that records in the form of analog audio signals. Ru.

0002

[Conventional technology]

FIG. 2 shows a CD player 1, a cassette deck 8, an output amplifier 5, and a speaker 1. 2 shows an audio device consisting of two parts. The disc played on CD player 1 The digital audio signal is converted to an analog signal by the D/A converter 2. , is led out to the analog output terminal 3. Note that 4 is a digital output terminal, and C A digital audio signal to be played by the D player 1 is derived.

0003 The analog audio signal obtained from the analog output terminal 3 of the CD player 1 is output. The power is supplied to the speaker 12 via the power amplifier 5.

0004 Also, the analog audio signal obtained from the analog output terminal 3 of the CD player 1 The number is supplied to the recording unit 13 via the CD input terminal 9 of the cassette deck 8, and is recorded on the magnetic tape. recorded in the loop.

[0005] Note that the external output terminal 6 of the output amplifier 5 is connected to the external input terminal 10 of the cassette deck 8. is connected to the output terminal 6, and is output from the output terminal 6 in response to switching (switching means not shown). The analog audio signal is supplied to the recording unit 13 so that it can be recorded on the magnetic tape. has been done. In addition, the external output terminal 11 of the cassette deck 8 is external to the output amplifier 5. The playback audio is connected to the input terminal 7 and output from the output terminal 11 according to the switching. The output signal can be supplied to the speaker 12 via the output amplifier 5.

[0006]

[Problem that the idea aims to solve]

By the way, according to the above configuration, the output to the analog output terminal 3 of the CD player 1 is is supplied to the CD input terminal 9 of the cassette deck 8. recorded. In other words, since the signal is transmitted in analog signal format, noise may occur along the way. There is a possibility that the recorded sound quality in the recording section 13 may deteriorate.

[0007] Therefore, this idea provides a tape recorder that can always record with good sound quality. It is something that

[0008]

[Means to solve the problem]

This idea consists of an input terminal for digital audio signals and a digital audio signal from this input terminal. A D/A converter that converts digital audio signals to analog signals, and /A recording section for recording analog audio signals from the A converter. It is something.

[0009]

[Effect]

The digital audio signal is converted to an analog audio signal by the D/A converter 22. For example, it can be converted to digital output terminal 4 of CD player 1 and recorded. It becomes possible to supply and record the output digital audio signal. digi Since the signal can be transmitted in the digital signal format, it is difficult for noise to enter on the way, and the signal is always in good condition. You will be able to record with high quality sound.

【Example】

An embodiment of this invention will be described below with reference to FIG. This figure 1 2, the same reference numerals are given to the parts corresponding to those in FIG. 2, and detailed explanation thereof will be omitted. Book In the example, the cassette deck 8 is provided with a digital input terminal 21 and , and a D/A converter 22 are built-in. Digital input terminal 21 is a D/A converter. The output side of this D/A converter 22 is connected to the input side of the D/A converter 22. 3 to the recording section 13 and to the CD input terminal 9.

[0011] The digital output terminal 4 of the CD player 1 is connected to the digital output terminal 4 of the cassette deck 8. It is connected to the input terminal 21. Also, only the CD input terminal 9 of the cassette deck 8 is connected to the output amplifier 5, and the analog output terminal 3 of the CD player 1 is connected to the output amplifier 5. 5 is not connected.

0012 Next, the operation of this example will be explained. Digital output terminal 4 of CD player 1 The digital audio signal (optical signal) obtained from the cassette deck 8 is It is supplied to the D/A converter 22 via the digital input terminal 21 and converted into an analog signal. will be replaced. Then, when the switch 23 is turned on, the D/A converter 22 The output analog audio signal is supplied to the recording section 13 and the CD input terminal 9. It will be done. Therefore, in the recording section 13, the analog audio signal is recorded on the magnetic tape. recorded. In addition, the analog audio signal supplied to the CD input terminal 9 is output It is supplied to the speaker 12 via the amplifier 5, and the corresponding sound is output from the speaker 12. Powered.

[0013] In this example, the data output to the digital output terminal 4 of the CD player 1 is Digital audio signals can be supplied to the cassette deck 8 for recording. Since the audio signal can be transmitted to the cassette deck 8 in the format of The recording section 13 can always record with good sound quality. Also, the cassette The same analog audio signal recorded in the recording section 13 of the receiver 8 is output to the output antenna. Since it is supplied to the speaker 12 via the tap 5, the recorded sound itself can be monitored. There is an advantage.

[0014] Note that the above embodiment uses a digital audio signal output from the CD player 1. In this example, the data was supplied to the cassette deck 8 for recording, but the satellite broadcast tuner etc. When recording audio signals from audio equipment that outputs digital audio signals. The same structure can be used in other cases as well.

[0015] Although not described in detail, in conjunction with the switch 23, the conventional circuit system and the circuit system of the present invention are You may use it by selectively switching between the road system and the road system.

[0016]

[Effect of the idea]

As explained above, according to this invention, a D/A converter is built-in and the digital Can input and record digital audio signals, and transmits signals in the form of digital signals As a result, noise is less likely to occur during recording, and recording can always be made with good sound quality.
