Description
Technical field
The utility model relates to a kind of exhibition article, relates in particular to a kind of entertaining audio amplifier.
Background technology
Along with social development, country more and more payes attention to the cultivation of national quality of science, and science and technology center, the scientific and technological van that flows, School are all good Popular Science Education bases, and the vital tissue key element in these science popularization bases is exhibition articles.As exhibition article, except explaining well the principles of science, also should there is interest, can inquiry, could attract people's eyeball, excite the interest of people to science.
Along with scientific and technological development, various senior loud speakers have been deep into huge numbers of families, and loadspeaker structure, the principle of these technology maturations are all very complicated, are not technical professionals, the general understanding the principles of science wherein that is difficult to.
Utility model content
Goal of the invention of the present utility model is: from the requirement of exhibition article, by simple structure, a kind of showpiece that can ocular demonstration speaker operation principle is provided, it is a kind of entertaining audio amplifier, coil is fixed on to flat board upper, has broken through the trumpet-shaped structure of conventional loudspeakers, can allow people understand better the sounding essence of loud speaker, having can inquiry, and entertaining is pure.
The technical solution adopted in the utility model is:
A kind of entertaining audio amplifier, comprises the casing being spliced by plate body, is provided with function amplification equipment in described casing, and described function amplification equipment is provided with audio output port; On arbitrary of described casing, be fixed with coil, the two ends of described coil forms tone frequency channel wire, described tone frequency channel wire is connected on audio output port, the face that described casing is provided with coil is provided with magnetic, described magnetic is also mutually corresponding with the interior outside that coil lays respectively at casing, or described magnetic and coil are positioned at the same side of casing, and described magnetic is affixed on coil.
Owing to adopting said structure, substitute the horn-like surface structure of conventional loudspeakers by the casing being spliced by plate body, casing, as the carrier occurring, is fixed on coil on flat board, break through the trumpet-shaped structure of conventional loudspeakers, can allow people understand better the sounding essence of loud speaker.
Its principle of sound: coil is fixed on arbitrary of a casing, the two ends of coil is received by tone frequency channel wire on the audio output port of function amplification equipment, like this in the time of opening function multiplying arrangement, the magnetic field that the audio signal of size variation just makes the surrounding of coil change, on coil, place a magnetic, the magnetic field changing just can interact with magnetisable material, because coil is to be fixed together with the one side of casing, so casing will follow the frequency of sound to vibrate together, sound has just produced.In the time taking away magnetic, sound stops.Can allow the fine generation essence of understanding loud speaker of people by principle of sound, having can inquiry, and interesting pure.
As preferred version of the present utility model, described in be spliced into the plate body of casing thickness be 0.01～5mm.
Further, the material that is spliced into the plate body of casing described in adopts metallic plate, hardwood plate, composite plate, plastic plate, acrylic board or hardboard to make.
Owing to adopting said structure, by preferred thickness and material, guarantee to realize the sounding of loud speaker, and can also experience the alternative sounds that different materials sends, more can strengthen people's exploration desire.In the time that thickness is less than 0.01mm, because sheet metal thickness is less, vibration is frequent, and frequency strengthens, and the ripple of twice vibration in front and back is got excited mutually, cannot obtain sound; When thickness exceedes 5mm, a little less than the vibration of casing, frequency is lower, is also difficult to obtain sound.
There are several coil serial or parallel connections that vary in size and are distributed on casing.
Further, when described coil is located at box inside, make marks in the outside of the corresponding casing of coil, magnetic is attached on mark.
Owing to adopting said structure, people can be placed on magnetic according to the hobby of oneself position of different corresponding coil marks, for as exhibition article, have stronger interest.
Further, in arbitrary upper shed of described casing.
Owing to adopting said structure, in the upper shed of casing face, coil is in outside, and people can stretch into magnetic in opening and be close to the position that coil is corresponding, have extremely strong exploration desire and interest.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1, the utility model is simple in structure, does phonation board with flat board, has broken through the traditional horn-like structure of loud speaker, can allow people understand better the sounding essence of loud speaker.
2, the utility model is all hidden in power amplifier, coil in casing, can build a kind of atmosphere of mystery, excites people's the desire of probing into.
3, the utility model can be placed in science popularization museum and show, because it is simple in structure, light and handy, also can be used as scientific popularization caravan with car exhibition product.
4, preferably 0.01～5mm of Board material for box thickness, guarantees to realize the sounding of loud speaker, and can also experience the alternative sounds that different materials sends, and more can strengthen people's exploration desire.
5, when coil is arranged on box inside, make marks in the outside of the corresponding casing of coil, magnetisable material is placed on mark, can be placed on different corresponding coil mark positions according to the hobby of oneself, has and explores and interest; In the upper shed of casing face, coil is in outside, and people can stretch into magnetisable material in opening and be close to the position that coil is corresponding, have extremely strong exploration desire and interest.
