FIG. 2 is a block diagram for explaining the configuration of an embodiment of the terminal device of the present invention, and the broken line frame of the figure shows the terminal device. This terminal device is connected to an audio reproducing device 20 which reproduces broadcasting from various broadcasting stations through two audio channels. The broadcasting used by the audio reproducing device 20 is various broadcasting radio waves such as AM stereo broadcasting, FM stereo broadcasting, satellite broadcasting, and VHF audio multiplex broadcasting.
Not limited to such broadcast radio waves, cable broadcasting may be used.

The voice reproducing device 20 outputs a voice analog signal for narration for a question through a voice channel 1, and outputs a voice analog signal such as a correct answer and an incorrect answer through a voice channel 2 and a voice analog signal for playing back an answer. Audio input signal amplifier circuits 21 and 2, respectively
The voice signal of the narration for the question, which is amplified by 2, is outputted from the voice signal output device 28 through the voice signal arithmetic circuit 26 and the voice signal output circuit 27. Also, in parallel with the audio output of audio channel 1, the audio analog signal of audio channel 2 is DTMF.
(Dual Tone Modulation Frequency) Received by the tone receiver circuit 23, the number of questions, the number of answers, the correct answer number, etc. are sequentially stored in the CPU arithmetic circuit 24, and the reproduced sound at the time of answer selection is recorded in the voice synthesis circuit 25. Will be done. In this embodiment, since the voice analog signal of the question narration, the voice analog signal of correct answer, the incorrect answer, etc. and the voice analog signal for playing at the time of answer are carried by the broadcast radio wave, such a signal is previously transmitted to the broadcast radio wave. It is necessary to put on.

The DTMF tone receiver circuit is a technique used for push-button dial signals of telephones. A dial button of a telephone as shown in FIG.
697-941 Hz four kinds of frequency signals, and 1209
Up to 16 types of codes are expressed by a combination of 4 types of frequency signals of up to 1633 Hz. In this terminal device, a code represented by such a combination of two frequencies is assigned to the initial setting signal, the number of questions, the number of answers, the correct answer number, etc., and the DTMF tone receiver circuit 23 uses two types of combined frequencies. Separately, it is sent to the CPU arithmetic circuit as a signal such as a correct answer number.

The voice synthesis circuit 25, as shown in FIG.
ADPCM (Adaptive Delta PulseCode Modulation)
The circuit is used for recording and playback. ADPCM
Is a method for transmitting a coded signal having a resolution with a small signal width, and the difference between the coded signals is treated as a signal. In FIG. 4, the audio input signal amplification circuit 2 is used during recording.
The analog audio signal input from 2 is quantized and encoded by the AD / DA converter 30, differentially encoded by the ADPCM circuit 32, and sequentially stored in the RAM 35 through the memory controller 34. At this time, CP
In U24, since the reproduced sound area is determined by the DTMF tone, the CPU 24 sends a control signal to the logic controller 33 through the CPU interface 31 to control the memory controller 34 to record the reproduced sound. At the time of reproduction, the differential coded signal stored in the RAM 35 is sequentially ADPC processed by the memory controller 34.
The differential code is sent to the M circuit 32 and converted into a quantized code, and the quantized code is converted into an analog audio signal by a DA converter and output to the audio operation circuit 26.

Returning to FIG. 2, when the respondent hears the narration from the voice signal output device 28 and operates the selector switch 11, the CPU arithmetic circuit 24 compares the operation switch number with the correct answer number. However, if they match, the reproduced sound at the time of the correct answer from the voice synthesis circuit 25 is output to the voice signal calculation circuit 26, and is output as voice through the voice signal output circuit 27 and the voice signal output device 28. The audio signal arithmetic circuit 26 is a circuit having two inputs and one output,
Either input is output. At this time, the display drive circuit 29 is driven and the score and the like are displayed on the display device 10.

Next, the contents of the audio channels 1 and 2 shown in FIG. 5 will be taken as an example to describe more concretely with reference to the flow chart shown in FIG. FIG. 5 is a time-series representation of the sound to be reproduced. From the audio channel 1, the device operation explanation sound,
A voice analog signal is sequentially output in the order of question first explanation sound, answer request voice, blank, second question explanation voice. From voice channel 2, DTMF tone 1, DT
An audio analog signal is sequentially output in the order of MF tone 2, DTMF tone 3, correct answer reproduction voice signal, DTMF tone 4, incorrect answer reproduction voice signal, DTMF tone 5, margin ,.

For example, the DTMF tone 1 is initialized by the initial setting signal "* # 2 # 10", and the initialization, the two-choice problem, and the number of questions 1 are given.
It means 0. The next DTMF tone 2 is the correct answer number signal "A # 1 # 1 # 2", and the first answer is the correct answer in the first question, which means that there are two recordings. The next DTMF tone 3 is a reproduction sound 1 recording start signal "B # 1 # 10" at the time of selecting an answer, which means that a voice reproduction signal when the No. 1 switch is pressed is recorded for 10 seconds. Next D
TMF tone 4 is playback sound 2 when the answer is selected Recording start signal "B
# 2 # 5 "records the voice reproduction signal for 5 seconds when the No. 2 switch is pressed. The next DTMF tone 5 is the response input acceptance permission signal" C ", which permits the acceptance of the switch input for the response. In this way, DTMF tone 1 initializes the number of questions, DTMF tone 2 correct answer number 1 and the recorded part is DT.
It is possible to record a voice reproduction signal when the correct answer switch is pressed for MF tone 3 for 10 seconds, and to record a voice reproduction signal when the incorrect answer switch is pressed for DTMF tone 4 for 5 seconds. Are recognized and stored in the CPU 24. Therefore, a necessary reproduced sound is recorded by controlling the voice synthesis circuit based on the stored contents. In the blank portion after the response request is made on the voice channel 1, the CPU controls the voice synthesis circuit by giving a correct answer or an incorrect answer.

Next, the processing operation will be outlined with reference to FIG. 6. First, initialization processing is performed under the control of the CPU, and D
The initial setting signal is input by the TMF tone, and the number of questions and the number of answers are stored in the CPU (steps 100 to 104).
Then, the correct answer number signal is input by the DTMF tone and the correct answer number is stored in the CPU (step 10).
3, 104). Then, a reproduction sound recording start signal at the time of answer selection is input by the DTMF tone, the reproduction sound recording processing is performed, and the recording processing is performed until the number of times of recording processing matches the number of answers (steps 105 to 107). Then, when the answer input acceptance permission signal is input by the DTMF tone and the answer switch is input, the voice assigned to each answer is reproduced (steps 108 to 110). At this time, if the input switch is a correct answer, the score and the number of remaining questions are displayed on the display device, and the correct answer LED is displayed, and if the input switch is an incorrect answer, only the number of remaining questions is displayed (steps 111 to 113). ). The above processing is performed until the number of questions reaches the number of questions, and when the questions are completed, the total score is displayed.

In the above embodiment, the audio reproducing apparatus having the two-channel output for receiving the broadcast radio wave has been described as an example, but the present invention is not limited to this. For example, multi-channel tape recorder, stereo cassette tape recorder, CD player, MD player,
If there are two or more audio outputs such as a HiFi video tape recorder, an LD player, and a computer device with an audio output device, the data such as the narration for the question, the correct answer and the incorrect answer are stored in advance, and one voice is output. The channel can be used as a narration signal path, and the other audio channel can be used as an audio signal path for correct answer, incorrect answer, recording processing, etc., and similarly, the terminal device can be connected and operated. In that case, if the subject content, game content, etc. are displayed as an image on the display and specific explanations, problems are presented, correct answers, incorrect answers, etc. are given by voice signals, it becomes easier to understand the contents. In addition, I can further inspire learning and inspire the game,
