Description

DEVICE FOR LUSH PRE-LEARNING MUSIC TRAINING

This industrial model relates to the educational system, in particular, to means of teaching music to people of any age and can be used to develop children's musical abilities, for example, in studying musical literacy, and can also be used to master practical music.

A device for teaching a museum is known (see UK application No. I8I7004, C09 B 15/00 H04 M 11 / 00.19973) in which each student has a keyboard electronic musical instrument, for example, an electronic piano. The output signal from this instrument is transmitted to a loudspeaker or to a system consisting of a headphone and a microphone. They are connected with the rest of the device’s tools in a common system containing a similar keyboard instrument controlled by a teacher, which controls each student with the help of selector switches and can serve four groups of six students in each, and can also connect to each individual student to talk with him for educational purposes, the iai for him to play the tongue, or to demonstrate to the student the game on his own / ment, or to listen to the student play other students on their instruments.

six buttons. Students can play in an ensemble in a group or groups. For this purpose, the students' headsets are connected using a passive impedance circuit to the input and output lines of their instruments so as to decouple the lines from one another, to ensure that the input signal is attenuated in proportion to its signal when several instruments are loud in the room.

This known device has significant disadvantages:

-constructive complexity due to the presence of a large number of different switching elements, which reduces the reliability of the operation of the device;

-operational complexity, since for communication between the teacher and the student it is necessary to switch the selector switch button, change the resistance of the communication line and use the microphone from which the signal from the teacher enters the student’s headphone. phi feedback actions are repeated in the same order but by the student;

- the availability of life-threatening power supply, which requires the use of special means for the electrically safe use of NO 220 V 50 Hz; -,. H

- difficult implementation conditions, since a stationary specially equipped room is necessary due to the provision of appropriate power supply and a large number of various devices controlled by power supply.

for the teacher. Each student booth has an electronic musical instrument. in which headphones are connected via a switching circuit, as well as a microphone. At the teacher’s stand there is an electronic musical instrument to which headphones are connected, a switch through which a prohibition signal is sent to the switching circuits of the student stands, as well as a microphone and switches, with which the microphone and teacher’s instrument outputs are selectively supplied to the students ’headphones, and the output signals students' instruments and microphones - on the same teacher’s headphones. Thus, using the prohibition switch, you can disable communication between the instrument and the headphones, either for the entire group of students or for individual students.

This known device also has significant disadvantages, which are:

-constructive complexity due to the presence of a large number of switching circuits located in each stand;

- distortion of the sound of the instrument, which occurs due to the use of a microphone on both sides, whose signal is superimposed on the signal taken from the instrument and transmitted to the headphones;

-the presence of a stationary room due to the power supply in the software 4-200 V 50 Hz devices that still need to be provided with special means of electrical protection;

As a prototype, the well-known technical solution is selected. A device for group learning to play electronic musical instruments (see, for example, the application of Germany No. 2262657, G 09 B 15/00, 19.79), in which the transmission and reception of the extracted sound and dialogue managed by the teacher.

the device has many student consoles, each of which contains an educational electronic instrument, an electro-acoustic transducer for a student connected to the output of the educational instrument, a valve circuit connected between the output of the educational instrument and the electro-acoustic transducer, and an acoustoelectric transducer. In addition, there is a teacher’s console with an electronic musical instrument, an electro-acoustic transducer connected to the output of the teacher’s instrument, and connected to the first group of switches for selectively connecting the output of the acoustic transducer to the desired electro-acoustic transducer of the student’s remote, the teacher’s console also contains a second group of switches designed for selectively connecting the outputs of an electronic musical instrument of a teacher with an electronic teacher’s troaconic transducer. Moreover, the teacher’s console has a guide circuit for supplying the interrupt signal to the student’s control panels and a third group of switches designed to selectively connect the outputs of students' acoustoelectric transducers with the teacher’s electro-acoustic transducer.

This well-known technical solution eliminates a number of drawbacks of previously known inventions, in particular, improves operating conditions, since a third group of switches and a control circuit are used, which allow you to decouple the communication links between student panels and the teacher’s panel, reducing the mutual distortion of musical works performed.

ny shortcomings, which, in general terms, coincide with the shortcomings of previous known similar devices, namely:

-restricted place of application, due to the need to have a stationary room due to the power supply in BUT t 220 V 50 Hz, required for a known device;

-high cost of installation and commissioning, caused by the need to lay the power supply network in software-f 220, electrical switching systems switching and installation of many control panels, as well as adjusting tools in the workplace;

-constructive complexity, in particular, switching circuits,

An analysis of the existing scientific and technical level of devices for group learning of music shows that:

-devices are stationary;

- the system of switching and communication between the student and the teacher and vice versa has a high structural and electrical circuit complexity, since in addition to the head phones, a microphone is used, and the control panels are equipped with valve systems;

- to deploy the device, you need a specially equipped room (electrical safety requirements) due to the wiring of the mains power supply with voltage that is dangerous to human life, as well as due to the corresponding shielding of switching circuits (wires) from the interference from a parallel wire of alternating mains power supply and careless with them the treatment of students (children);

.

The background to the students and their headphones requires constant adjustment of the volume on the student’s remote control and the teacher’s remote, which tires both the student and the teacher, and also leads to rapid wear of the noise level controls.

If an attempt is made to sound a class through an amplifier with speakers, then very often there is an inverse acoustic connection between the speaker and the students' microphones, which causes the class amplifier system to self-excite.

Moreover, if the microphone is located in the center of the stand, then they interfere with the review of musical text, performed musical works. If micro |: it is located on the side of the stand, the student is distracted from the performance of the musical work due to the need to use the microphone to talk with the teacher.

At the same time, the presence of such well-known equipment for group teaching music in a classroom does not allow teaching other disciplines that are not related to music in such a class.

All this is due to the fact that, at the existing scientific and technical level, there is a tendency to complicate devices for group learning of music by introducing new nodes into them, converting them into a switching circuit and using a stationary room.

The inventive step, which determines the scientific and technical level, of the known inventions under consideration, is not high, since for a specialist of average qualification they logically follow from trends prevailing in the existing scientific and technical level. For example, the prototype logically follows from the previous two known inventions and is based on the introduction of known blocks, switching elements.
