Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a learning device suitable for use in, for example, an audiovisual education system.

[Outline of device]

This invention is a learning device in which a plurality of child devices are provided for a parent device and each of these child devices is operated by a plurality of learners. By making calls possible, joint work can be carried out smoothly.

[Conventional technology]

In a conventional learning device in an audiovisual education system, when a headset or the like in which a headphone and a microphone are integrated is used, the call is made to the teacher and the learner by a one-to-one or one-to-many method. It is common to make a call with a specific pair or group designated by the teacher.

On the other hand, a learning device has also been proposed in which one child machine is shared by a plurality of learners to perform joint work, and FIG. 4 is an example thereof.

In FIG. 4, (1) is a master unit, (2) is a plurality of slave units provided for this master unit (1), and the slave unit (2) is used by two learners. A first headset (3) and a second headset (4) are provided so that they can. Learners using the headsets (3) and (4) work individually or jointly according to the information and instructions from the master unit (1).

[Problems to be solved by the invention]

By the way, as described above, when one child machine is shared by a plurality of learners and collaborates, it is indispensable for the learners who are collaborating to collaborate freely. However, in this case, it is not possible for the learner to talk with the headset on, so on the contrary, the headset interferes with free calling, and it is necessary to take measures such as removing the headset during the call. It was difficult to work smoothly.

The present invention has been made in view of the above circumstances, and provides a learning device in which learners who do not work together can easily talk with each other while wearing headsets.

[Means for solving problems]

The learning device according to the present invention is a learning device in which a plurality of child devices (2) are connected to the parent device (1) and each of these child devices is operated by a plurality of learners. The change-over switches (16) and (17) are provided so that the persons can talk with each other, and the change-over switches (16) and (17) are controlled by a learner who operates the slave unit.

[Action]

A plurality of slaves (2) are connected to the master (1) so that each slave can be operated by a plurality of learners. Then, in the first operation mode in which the changeover switches (16) and (17) are provided on the child machine and the learners who share the child machine make mutual notifications, the changeover switch is closed to perform learning to share the child machine. In the second operation mode in which the persons are not informed of each other, the changeover switch is opened. As a result, learners who share the child device can dodge a conversation with each other at an arbitrary time, and collaborative work can be performed smoothly.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows the circuit configuration of the slave unit when two learners share one slave unit. In FIG. 1, (10) is the microphone for the learner on one side, and (11) Is a headphone thereof, and these microphones (10) and headphones (11) constitute a one-sided headset. The output side of the microphone (10) is connected to the master unit (1) (Fig. 4) and the mixer
Connected to the first input terminal of (12). Further, (13) is a microphone for a learner on the other side, and (14) is a headphone thereof. These microphones (13) and headphones (14) constitute a headset on the other side. The output side of the microphone (13) is connected to the master unit (1) and also to the first input terminal of the mixer (15). The outputs from the master unit (1) are supplied to the second input terminals of the mixers (12) and (15).

Further, two interlocking changeover switches (16), (17) are provided, one side of the switch (16) is connected to the first input terminal of the mixer (12), and the other side of the switch (16) is Connected to the third input terminal of the mixer (15), one side of the switch (17) is the mixer (12)
Of the switch (17) and the other side of the switch (17) is connected to the first input terminal of the mixer (15). Also a mixer
The output side of (12) is connected to the headphones (11) via the amplifier (18), and the output side of the mixer (15) is connected to the headphones (14) via the amplifier (19).

In the second operation mode in which the learners on one side and the learner on the other side do not notify each other, the switches (16) and (17) are released. Then, the audio signals from the microphones (10) and (13) are supplied to the master unit (1), respectively, and the headphones (11) and (14) of the own unit are supplied.
The output from the master unit (1) is supplied to the headphones (11) and (14), respectively.

In the first operation mode in which the learners on one side and the learner on the other side make mutual notifications, the switches 16 and 17 are simultaneously closed.
Then, the audio signals from the microphones (10) and (13) are supplied to the master unit (1) and the own headphones (11) and (14), respectively, and the headphones (14) and (11) on the other side are supplied. Is also supplied to the side. Also, the output from the master unit (1) is the headphones (11),
It is supplied to the (14) side as described above. In this way, the voice signals can be transmitted from the own microphones (10) and (13) to the headphones (14) and (11) of the other party, respectively.
It is possible to make a report between learners who share a child machine, and to facilitate joint work. At this time, the conversation passed between the learners can be monitored on the master side.
