First Embodiment

When a teacher wants to monitor a predetermined student among students participating in learning through a local area network, the signal flow between the audio hub circuit unit 20 and the headset adapter circuit unit 30 of the learning system implementing apparatus according to the present invention will be described with reference to FIG. 4. The explanation is as follows.

First, each learner 40-1 to 40-n of the learning performer 40 before the teacher monitors a predetermined student is in a class based on the learning information transmitted by the teacher.

That is, when the operation of the headset adapter circuit unit 30-1 to 30-n according to each learner 40-1 to 40-n is illustrated in FIG. 3, the headset adapter circuit unit according to the learner is described above. The predetermined learning information transmitted from the audio circuit unit 23 of the audio hub circuit unit 20 is received.

Here, since the headset adapter circuit unit of each learner according to a predetermined student performs the same operation, the headset adapter circuit unit 30-1 of the first learner 40-1 according to the first student will be described as an example. The adapter circuit unit 30-1 'turns on' the internal CONF switch element 30-1a to transmit the voice signal of the student according to the first learner 40-1.
