Abstract
A kind of convenient teaching radio loudspeaker of high-performance, including sound amplifier body, washable storage box, USB jack, elastic waistband, it is characterised in that the positive Middle face of sound amplifier body is provided with double magnetic horns；Washable storage box is provided with the right side of the sound amplifier body；The sound amplifier body back side both sides are separately installed with aluminium alloy button, and are connected with each other by elastic waistband.The utility model has the advantage of by being mounted with double magnetic horns, the loudness of sound amplifier is improved, increases it and responds audiorange so that the student of classroom every nook and cranny can clearly hear sound, lift the quality of education, alleviate the burden of teacher.The washable storage box set at the same time can place the classroom such as USB, chalk, pen articles for use, greatly facilitate teacher and use classroom articles for use, improve efficiency of teaching.The elastic waistband set at the same time quickly can wear or remove sound amplifier, and can firmly be adjacent in loins, and facilitating teacher, movement is given lessons in classroom.
Description
Technical field
Sound amplifier technical field is the utility model is related to, more particularly, to a kind of convenient teaching radio loudspeaker of high-performance.
Background technology
Teacher in daily teaching, often will be big throat teach, be in for a long time in this working status and environment, it is inevitable
Throat even health can be jeopardized.In order to facilitate the teaching of teacher, efficiency of teaching is improved, and also to protect old
The throat of teacher, public-address amplifier for teaching come into being.Traditional teaching public address system is based on wired, existing teaching public address system
Then based on wireless type, especially in current institution of higher learning, wireless teaching sound amplifier is all used mostly.It is but existing wireless
Public-address amplifier for teaching loudness is inadequate, causes the student remote apart from teacher not hear the sound of teacher, and influence is listened to the teacher and learning quality.Together
Shi Buneng stores the classroom ordinary articles such as chalk, pen, USB for teacher, it is impossible to liberates the both hands of teacher and cannot preferably improve
Efficiency of teaching.For solve above sound amplifier there are the shortcomings that, now provide a kind of high-performance convenient teaching radio loudspeaker, can jail
Solid be fixed on teacher's loins, facilitate teacher movement give lessons, it is possible to increase the loudness of sound amplifier, increase response audiorange, make
Sound can clearly be heard by obtaining the student of classroom every nook and cranny, be improved the quality of teaching.USB, chalk, pen can be placed at the same time
Deng classroom articles for use, teacher's both hands are liberated, teacher is greatly facilitated and uses classroom articles for use, improve efficiency of teaching.
The content of the invention
The purpose of this utility model is to provide a kind of convenient teaching radio loudspeaker of high-performance, by installing double magnetic loudspeakers
, the loudness of sound amplifier is improved, increases it and responds audiorange so that the student of classroom every nook and cranny can clearly listen
To sound, the quality of education is lifted, alleviates the burden of teacher.By setting washable storage box, Neng Goufang in sound amplifier main body
The classroom such as USB, chalk, pen articles for use are put, teacher is greatly facilitated and uses classroom articles for use, improve efficiency of teaching.Pass through rubber at the same time
Muscle waistband quickly can wear or remove sound amplifier, and can firmly be adjacent in loins, and facilitating teacher, movement is awarded in classroom
Class.
The technical solution of the utility model is：A kind of convenient teaching radio loudspeaker of high-performance, including sound amplifier machine
Body, washable storage box, USB jack, elastic waistband, the positive Middle face of sound amplifier body is provided with double magnetic horns, described
Double magnetic horns formed successively by T-shaped iron, magnet 1, magnet 2, Hua Si, double magnetic horn body combinations, double magnetic horn masters
Live wire is set on body, and the electric wire links together with circuit board, and the sound amplifier body top right side is provided with sound
Amount switch, the volume switch are connected with circuit board；Washable storage box, institute are provided with the right side of the sound amplifier body
The washable storage box left side top stated is screwed on the right side of sound amplifier body；The sound amplifier body back side both sides
Aluminium alloy button is separately installed with, the aluminium alloy button is connected with each other by elastic waistband.Teacher is by being entangled in elastic waistband
On waist, the aluminium alloy for then both ends being buckled in the sound amplifier back side is buckled.Since elastic waistband is elastic so that sound amplifier being capable of jail
Solid tie up on waist, operating process is simple, quick, convenient.When sound amplifier works, double magnetic horns pass through magnet 1 and magnet 2
Attract each other, effectively strengthen permanent magnetic field, under same power, effectively raise loudspeaker loudness, increase it and respond audio
Scope so that sound is more clear, more loud, propagation farther, effectively raises quality of instruction.And pass through volume
The loudness of the double magnetic horns of switch control, control volume rationally, healthy.Teacher can be placed on pen, chalk, USB removable at the same time
Wash in storage box, when writing blackboard word can easily, quickly replace chalk, improve efficiency of teaching；Can using pen when
Wait, quickly taken out from washable storage box, it is not necessary to go on dais and take or find, it is very convenient, flexible.Can be being finished
USB at once place, avoid losing.
The utility model has the advantage of by installing double magnetic horns, the loudness of sound amplifier is improved, increases it and responds sound
Frequency scope so that the student of classroom every nook and cranny can clearly hear sound, lift the quality of education, alleviate the negative of teacher
Load.By setting washable storage box in sound amplifier main body, teacher's both hands are liberated, teacher is greatly facilitated and uses classroom articles for use,
Improve efficiency of teaching.Sound amplifier quickly can be worn or remove by the elastic waistband of setting at the same time, and can be firmly
It is adjacent in loins, facilitating teacher, movement is given lessons in classroom.
