Description
Technical field：
It the utility model is related to a kind of multimedia teaching control device.
Background technology：
At present, impart knowledge to students and the multimedia integrated system of business meetings in, control device is connection and to regulate and control other each
The central apparatus of equipment, at present, in teaching, middle control is typically only capable to disposably access a kind of signal, when teaching process needs are more
, it is necessary to which first disconnecting the signal accessed changes another signal access into during kind signal switching, using being inconvenient, teaching work is given
Bring puzzlement；In addition, current control device mostly uses mechanical key, mechanical key service life is shorter, often
Break down, made troubles to use.
Utility model content：
The utility model provides a kind of multimedia teaching control device, and it is reasonable in design, is set in control device
Multiple signal access interfaces are put, multiple signals can be accessed simultaneously, are realized by the way that different signals to be carried out to the regulation of volume
Switching between unlike signal, it is no longer necessary to disconnect a kind of signal and access another signal again again, brought just to teaching
Profit, in addition, using capacitance touch button, the service life of button is substantially prolongs, is offered convenience to use, it is existing solving
Problem present in technology.
The utility model is that technical scheme is used by solving above-mentioned technical problem：
A kind of multimedia teaching control device, including a control device body, connect on control device body provided with USB
Mouth, HDMI, TRS interfaces, XLR interfaces, the USB interface, HDMI, TRS interfaces, XLR interfaces are adjusted with a volume
Regulating device is connected, and volume adjustment device is connected with loudspeaker, and the volume adjustment device includes the first volume being connected with USB interface
Adjusting switch, the second level setting switches being connected with HDMI, the 3rd level setting switches being connected with TRS interfaces and with
The 4th connected level setting switches of XLR interfaces.
VAG interfaces are provided with control device body, pressure sensor, pressure sensor are provided with the inner side of USB interface
It is connected with being arranged on the intrinsic controller of control device, controller is arranged on the buzzer phase on control device body with one
Even.
Button on control device body is capacitance touch button.
The utility model uses said structure, and multiple signal access interfaces are set on control device body, can be simultaneously
Multiple signals are accessed, the switching between unlike signal is realized by the way that different signals to be carried out to the regulation of volume, it is no longer necessary to
Disconnect a kind of signal and access another signal again again, offered convenience to teaching, in addition, using capacitance touch button, greatly
The big service life for extending button, offers convenience to use.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Fig. 2 is USB interface buzzer structural representation of the present utility model.
In figure, 1, control device body, 2, volume adjustment device, the 3, first level setting switches, the 4, second volume adjusting
Switch, the 5, the 3rd level setting switches, the 6, the 4th level setting switches, 7, VAG interfaces, 8, pressure sensor, 9, controller,
10th, buzzer.
Embodiment：
For the technical characterstic for illustrating this programme can be understood, below by embodiment, and its accompanying drawing is combined, to this reality
It is described in detail with new.
As shown in figs. 1-2, a kind of multimedia teaching control device, including a control device body 1, in control device sheet
Body 1 is provided with USB interface, HDMI, TRS interfaces, XLR interfaces, the USB interface, HDMI, TRS interfaces, and XLR connects
Mouth is connected with a volume adjustment device 2, and volume adjustment device 2 is connected with loudspeaker, and the volume adjustment device 2 includes and USB
The first connected level setting switches 3 of interface, the second level setting switches 4 being connected with HDMI, are connected with TRS interfaces
3rd level setting switches 5 and the 4th level setting switches 6 being connected with XLR interfaces.
VAG interfaces 7 are provided with control device body 1, pressure sensor 8 is provided with the inner side of USB interface 7, pressure passes
Sensor 8 is connected with the controller 9 being arranged in control device body 1, and controller 9 and one is arranged on control device body 1
Buzzer 10 is connected.
Button on control device body 1 is capacitance touch button.
Carrying out in use, each road audio input is connected to each audio input interface on control device body 1, when need
Will certain when audio plays out all the way, this audio all the way adjusted by volume adjustment device 2 it is larger to volume, while by its
His road volume adjusting is to minimum, when setting by the minimum status adjustment of volume to mute state.Connect if desired for USB interface is played
The audio entered, the first level setting switches 3 are adjusted to larger volume, while the second level setting switches 4, the 3rd volume are adjusted
Section switch 5, the 4th level setting switches 6 are adjusted to minimal volume, you can play out the audio that USB interface accesses.
When VAG interfaces 7 have access, pressure sensor 8 sends signal to controller 9, and buzzer 10 do not work, when not having
Pressure sensor 8 does not send signal to controller 9 during access, and buzzer 10 is opened, and prompts VAG interfaces 7 to pull out line.
The setting of capacitance touch button causes the service life of button to greatly prolong.
Using multimedia teaching control device of the present utility model, multiple signals are set to access on control device body 1
Interface, multiple signals can be accessed simultaneously, realized by the way that different signal to be carried out to the regulation of volume between unlike signal
Switching, it is no longer necessary to disconnect a kind of signal and access another signal again again, offered convenience to teaching, in addition, using electricity
Hold touch key-press, substantially prolongs the service life of button, offered convenience to use.
Above-mentioned embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art
For art personnel, any alternate modification or conversion made to the utility model embodiment all fall within guarantor of the present utility model
In the range of shield.
Part is not described in detail for the utility model, is the known technology of those skilled in the art of the present technique.
