Description
Technical field
The present invention relates to audio-visual devices technical field, specially a kind of durable English teaching public address equipment.
Background technology
Loudspeaker is commonly called as power amplifier abbreviation power amplifier, is equipment most basic in sound system, and its task is to coming
It is amplified from the ultra-weak electronic signal of signal source (being then to come from sound console in professional sound system) and sound is sent out with drive the speaker
Sound is mainly mainly used for teaching, tour guide, outdoor, lecturing activity, have that volume is relatively small and can be suspended on and volume
It is relatively large carry out carry be placed on the places such as teacher and conference hall, type and purposes are more.
As student's quantity that the constantly universal and each colleges and universities of compulsory education receive is increasing, teacher is in teacher
When teaching, since classroom area is excessive and classroom number of student is relatively more, when being imparted knowledge to students, only
Make a sound if attending class, to be sitting in that classmate comparatively rearward just can not will be apparent that by teacher hears teacher
The content of upper teaching, so now in the teaching process of some schools, more and more teachers are carried out using loudspeaker
Teaching work ensures the quality attended class, and when being used, power amplification device generally can directly be put traditional public address equipment
It sets and is teaching indoor a certain position, but traditional public address equipment is placed when is easy to indoor student is taught to touch and occur
It shakes and even overturns, as the loudspeaker of electronic equipment, shatter-resistant anti-seismic performance will directly influence the use of public address equipment
Service life, and the public address equipment used as school instruction, normal condition have the working time close to more than ten a hours for lower day,
Prolonged high load capacity work and Classroom air temperature are relatively high, and public address equipment internal temperature is relatively common higher, although
Electrical equipment now can be operated under high temperature environment, but prolonged high load capacity running still can seriously affect expansion
The service life of sound equipment, and when imparting knowledge to students use, traditional public address equipment generally can all be selected in the inner cavity of equipment
It is configured radiator structure and carries out cooling effect, but this is for the public address equipment of intensive work or far from enough
, but when adding radiator outside, will produce a large amount of noise, the matter that public address equipment makes a sound can be seriously affected
Amount.

Operation principle：In use, public address equipment is placed on one jiao of classroom, when public address equipment works, due to
Power problem can make the action that loudspeaker ontology is constantly shaken in the inner cavity of shell, and loudspeaker ontology is constantly shaking
When, the ontology that amplifies constantly is pressed down against buffer board, and the top of the eastern folding shaft of buffer board band is rotated around strip, folded
When shaft rotation is moved, bottom pushes movable sleeve to be drawn close to outer casing inner wall along the direction of buffer shaft, when being actively set on mobile
It waits, squeezes spring and deform upon, spring prevents loudspeaker ontology that buffer board is driven to continue to move down using the elastic force of itself,
When spring reaches critical value, slowly movable sleeve can be pushed mutually to draw close, folding rod and buffer board is pushed to move up, it is whole
Caused by a process is all the vibrations generated with the loudspeaker ontology use of time, meanwhile, it is squeezed by noon in public address equipment
When pressure is fallen down, anti-fall mechanism can equally carry out above-mentioned action to carry out cushioning effect, and public address equipment is avoided to be hit
It hits and is damaged, external power supply drive motor rotation, motor is turned by output shaft, wheel disc and belt come drive shaft
It is dynamic, shaft seal box send out inner cavity drives flabellum rotation, flabellum rotation to give out loudspeaker body bottom portion by blast pipe
The hot-air come is detached, and says that the conveying that detaches of seal pipe was emitted into outside air later, when additional long as far as possible
Between the public address equipment that works carry out heat discharging operation, burnt than meter Na Qi internal component because temperature is excessively high.
(3) advantageous effect
Compare the prior art, the cooperation that the present invention passes through shell, anti-fall mechanism, loudspeaker ontology, fixed strip and snib
