Description
Technical field
The utility model relates to a kind of public address equipment field, in particular to a kind of English teaching being convenient for carrying is set with amplifying
It is standby.
Background technique
Loudspeaker is exactly to amplify sound as its name suggests, the farther meaning of propagation, loudspeaker for opposite speaker
Sound penetration it is stronger.
Loudspeaker can respectively have it to use where advantage according to its volume, usage mode and purposes there are many type.It is portable
For formula loudspeaker because shape size, loudspeaker are limited, general power all only has 3--8W.And wireless microphone and wired intercom then body
Product size is variant, and purposes is different, and suitable teacher, the tour guide of small volume use, and hangs over loins, plays both hands more certainly
By power is generally also in 3W-8W.It is bulky to be suitable for the big ground of flows of the people such as outdoor activity, summer camp, extracurricular speech
Side, power is then in 35W---95W.Lithium bullhorn is then one of to be made to classify according to the battery types that it is used.It is solved
Pollution problem of the conventional dry cell batteries of having determined to environment, it mainly uses mobile phone lithium power technology to power to loudspeaker.
With loudspeaker, there is some shortcomingss in use for existing teaching, and if volume is larger, carrying is not
Very convenient, shell is mostly that plastics are made, and shatter-resistant ability is poor, only one loudspeaker that amplifies of loudspeaker easy to damage and present
, left and right acoustic channels and stereo-circulation sound cannot be set, the farther away student's hearing for being sitting in the right and left substantially in classroom then can
Without so good, limitation is larger.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of existing technologies, and provides a kind of English being convenient for carrying
Public address equipment is used in teaching.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution:
A kind of English teaching public address equipment being convenient for carrying of the utility model, including shell and hand handle, the shell
Top wall surface side is equipped with volume knob, and the other side far from the volume knob arranges be equipped with L channel respectively
Button, stereo-circulation button and right channel button, the volume knob and L channel button, stereo-circulation button and right sound
Road button is to be electrically connected, and is provided with loudspeaker at shell front surface center, and is put together centered on the loudspeaker

Side be equipped with loudspeaker switch button, lower section is provided with USB interface in the bluetooth connection button and loudspeaker switch button,
And it is located at the USB interface and is arranged right below battery case.
As a kind of optimal technical scheme of the utility model, shell is made of metal material, and length is 30cm, wide
Degree is 20cm.
As a kind of optimal technical scheme of the utility model, the volume knob is that surface is helicitic texture.
As a kind of optimal technical scheme of the utility model, the hand handle has the deformable structure of certain elasticity, and
Additional rubber package.
As a kind of optimal technical scheme of the utility model, battery is installed in the battery case.
As a kind of optimal technical scheme of the utility model, the battery case respectively with loudspeaker, three-dimensional loudspeaker, bluetooth
Button, loudspeaker switch button and USB interface is connected to be electrically connected.
The utility model beneficial effect achieved is: the shell of setting be metal material made of, have it is higher
Intensity, and be rectangle structure length be 30cm, width 20cm, so that the loudspeaker is compact-sized, volume is less than normal, carries ten
The convenience divided, and there is certain shatter-resistant collision resistance, there is the deformable structure of certain elasticity secondly by hand handle, and outside
Add rubber to wrap up, comfort level is improved when lifting, is listened by the stereo-circulation sound of setting, left and right acoustic channels when teacher plays English
It when power, is not heard convenient for entire classroom student, amplifying effect is good, while the bluetooth connection button being arranged, and is amplified by mobile phone connection
Device can play or suspend on mobile phone, and easy to use, user can grasp USB flash disk, IF card or other digital equipments
