detailed description

There are multiple desks and a podium in the classroom. There is a computer on the podium. The computer is connected to a projection device and an input device. The projection device is used to project courseware and images or audio and video that the teacher needs to display. The input device includes a mouse and a keyboard. Used to control the computer.

There is a socket on each desk. The socket is connected to the power supply unit and the signal switch. To provide low-voltage direct current for student units, one power unit can have multiple outputs, one is connected to the mains input, and the signal end of each socket is connected to a signal switch, and the signal switch sends the signals to the computer, and the computer can display the connection status of the socket , and send a signal to the socket through the computer.

The system has multiple student units, each student unit has the same structure, and the student unit is fixed in the base, which is convenient for storage, carrying, and placement. The base is equipped with an earphone holder for hanging the student's earphones, and the earphone holder is a column with a hook. A lighting lamp is provided on the top of the earphone base, which can provide illumination for students and facilitate fixing the students' earphones. The button unit and indicator light are fixed on the upper surface of the base, and the plug is connected to the sub-processor in the base through wires. The plug of the student unit is matched with the socket, and the socket not only provides direct current for the plug, but also transmits signals with the plug. The sound signal and authorization signal sent by the computer are sent to the sub-processor through the switch and the socket, and the sub-processor will feed back the status of the received signal to the signal light , and output the sound signal value to the earphone of the student. The earphone of the student includes a loudspeaker and a microphone. In the case of authorization, the microphone outputs the audio signal, and the key unit outputs the key signal to the sub-processor. The sub-processor outputs the audio signal and the key signal through the plug, The socket and the signal switch are sent to the computer, and the button unit can simultaneously output the button signal to the sub-processor to adjust the lighting lamp and the student's earphone.

The indicator light includes the microphone on indicator light, the power indicator light, and the signal receiving status indicator light, which can display whether the signal transmission of the current student unit is normal, whether the power supply is normal, and the button unit includes the answer button area, the question button, the volume adjustment button, and the light The switch button can facilitate the interaction between students and teachers.

In order to monitor the students’ listening status, the earphones of the students include two earhooks with fixed speakers. The opposite side of the earhooks is provided with a pressure sensor. The pressure sensor outputs a pressure signal to the sub-processor. Put off the earphones and don't listen to the class.

The system is equipped with a teacher unit, the teacher unit is equipped with a teacher earphone, a first communication unit connected to the teacher earphone, and a battery for powering the teacher unit, the battery needs to be easily replaced or charged, the first communication unit communicates with the second communication unit, and the computer The second communication unit is connected, the first communication unit and the second communication unit can use bluetooth communication or other wireless communication methods, the teacher's earphone includes a loudspeaker and a microphone, and the teacher's voice is sent to the earphone of each student unit through the computer, and can Receive the sound from one or more students' earphones in the authorized state.
