Description
Technical field
The utility model relates to a kind of teaching field, the special loudspeaker of especially a kind of Multifunctional mathematics teaching.
Background technology
Loudspeaker, as the supporting industry of household electrical appliances, computing machine, mobile phone, automobile and other industries, is closely connected with its development.Loudspeaker is the same with consumer electronics product, life cycle is shorter and shorter, update speed goes is fast, but, the problems such as present loudspeaker carries inconvenience, and sound is little, therefore a kind of novel special loudspeaker of excellent quality Multifunctional mathematics teaching will cater to the demand in market, facilitate teacher to use at teaching link, improve the quality of teaching.
Utility model content
For the problems referred to above, the utility model aims to provide a kind of easy to carry, and function perfects, the special loudspeaker of Multifunctional mathematics teaching of long service life.
For realizing this technical purpose, scheme of the present utility model is: the special loudspeaker of Multifunctional mathematics teaching, at least comprises loudspeaker, volume knob, loudspeaker switch, earphone interface, microphone interface, link, Philip's head screw, charging socket, TF card jack, charging indicator light; Loudspeaker top is located at by loudspeaker, rounded; Device middle and upper part is provided with a circle groove, prevents device landing in use; Volume knob is located at the below of groove, the right side of device; The below of groove is located at by loudspeaker switch, the left side of device; Earphone interface is located at loudspeaker switch right-hand member; Microphone interface is located at volume knob left end and is positioned on the right side of earphone interface; Link is located at the bottom of device; Device bottom and device are fixed together by Philip's head screw; Charging socket is located at the central authorities of bottom of device; TF card jack is located at the top of charging socket and is positioned near link; Charging indicator light is located at below charging socket; The device back side is also provided with data line socket.
As optimisation technique scheme of the present utility model: the built-in rechargeable lithium battary of loudspeaker; Micropkonic shell adopts aluminium alloy baking finish process to make.
Compared with prior art, the beneficial effects of the utility model are: micropkonic shell adopts aluminium alloy baking finish process to make, and improves the micropkonic life-span; The design of this loudspeaker outward appearance, reduces volume, improves volume, facilitates teacher to use at teaching link, is satisfied with the requirement of giving lessons of large lectures, and be especially applicable to math teacher and use, improve the quality of teaching, tonequality is good, long service life, is applicable to promoting the use of.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model;
Fig. 2 is polycrystalline substance schematic diagram of the present utility model;
Wherein: loudspeaker 1, volume knob 2, loudspeaker switch 3, earphone interface 4, microphone interface 5, link 6, Philip's head screw 7, charging socket 8, TF card jack 9, charging indicator light 10.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, in the utility model embodiment, the special loudspeaker of Multifunctional mathematics teaching, at least comprises loudspeaker, volume knob, loudspeaker switch, earphone interface, microphone interface, link, Philip's head screw, charging socket, TF card jack, charging indicator light; Loudspeaker top is located at by loudspeaker, rounded; Device middle and upper part is provided with a circle groove, prevents device landing in use; Volume knob is located at the below of groove, the right side of device; The below of groove is located at by loudspeaker switch, the left side of device; Earphone interface is located at loudspeaker switch right-hand member; Microphone interface is located at volume knob left end and is positioned on the right side of earphone interface; Link is located at the bottom of device; Device bottom and device are fixed together by Philip's head screw; Charging socket is located at the central authorities of bottom of device; TF card jack is located at the top of charging socket and is positioned near link; Charging indicator light is located at below charging socket; The device back side is also provided with data line socket.
As optimisation technique scheme of the present utility model: the built-in rechargeable lithium battary of loudspeaker; Micropkonic shell adopts aluminium alloy baking finish process to make.
Utility model works principle: in magnetic-type teaching loudspeaker structure, the electromagnet of a movable core is had between permanent magnet the two poles of the earth, when not having electric current in magnet spool, movable core, by the attraction of permanent magnet two magnetic pole equal levels attractive force, keeps static in central authorities; When there being electric current to flow through in coil, movable core is magnetized, and becomes a bar-shaped magnet.Along with the change of direction of current, the polarity also respective change of bar-shaped magnet, makes movable core rotate around fulcrum, and the vibration of movable core is passed to vibrating diaphragm by cantilever and promoted air thermal vibration, makes teaching loudspeaker send the sound; Micropkonic shell adopts aluminium alloy baking finish process to make, and improves the micropkonic life-span; The design of this loudspeaker outward appearance, reduces volume, improves volume, facilitates teacher to use at teaching link, and be satisfied with the requirement of giving lessons of large lectures, improve the quality of teaching, tonequality is good, long service life, is applicable to math teacher and uses.
In addition, the design of link, prevents loudspeaker from losing because volume is little.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
The above, be only preferred embodiment of the present utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
