Description
Technical field
The utility model relates to a kind of broadcasting audio amplifier, particularly a kind of remote-controlled broadcasting audio amplifier.
Background technology
Broadcast system is one of each indispensable infrastructure of school, although video technique and network technology were in development at full speed in recent years, broadcast system is still used by all kinds of school with its practicality, economy, convenience.The existing all kinds of schools of China all have Public Address system basically, and it is mainly used in various public arenas, as hold whole school activity, notify, raise national flag, setting-up exercises during the break, broadcasting break music, school National Games, hold whole school's conference etc.And the broadcasting audio amplifier is a part of Public Address system, and it is bringing into play very important effect in whole broadcast system.Most schools utilize broadcast playback the tinkle of bells or carry out multimedia teaching on class or after class usually, for example utilize broadcast system to carry out phonetic teaching, the particularly enforcement of the popularizing of music tone ringer, English Listening Comprehension examination etc., in order to make each student can both hear the sound that the broadcasting broadcast comes, in each classroom, each dormitory building, playground all be equipped with the broadcasting audio amplifier, the student can both very clearly hear broadcasted content like this.Because the tinkle of bells rings twice usually on class, teacher has entered the classroom on class when sound is primary, when sound is secondary, teacher's teaching of having to stop, wait for after the tinkle of bells stops and continuing on class again that this will have influence on the progress that teacher gives a lesson, and want undisturbedly to see a little reference books or data sometimes after school in the classroom, and therefore this moment when school goes on the air just needs a kind of audio amplifier of controllable switch.
The utility model content
The utility model is exactly uncontrollable and can have influence on the give a lesson defective of student reading of teacher in order to solve existing audio amplifier, and a kind of remote-controlled broadcasting audio amplifier is provided.
The technical problem of the required solution of the utility model can be achieved through the following technical solutions:
A kind of remote-controlled broadcasting audio amplifier of the present utility model, comprise the audio amplifier body, it is characterized in that, described audio amplifier body connects an infrared receiving module, described infrared receiving module connects a power supply, described remote-controlled broadcasting audio amplifier also comprises an Infrared remote controller, is provided with an infrared transmission module in the described Infrared remote controller, and described Infrared remote controller shell is provided with the switch setting.
Owing to adopted technique scheme, the beneficial effect that the utlity model has is: compared with prior art, the utility model can be controlled the switch and the volume of broadcasting audio amplifier flexibly and comfortably, and is simple in structure, practical.
