Description
Technical field
The present invention relates to wireless charging and loud speaker field, be specifically related to a kind of and the integrated wireless charging receiving terminal of loud speaker.
Background technology
Along with the progress of science and technology and the raising of people's living standard, mobile phone, panel computer, MP4 etc. have become requisite consumer electronics in our daily life.Traditional charging modes of these electronic products is to insert in the home circuit with special-purpose charger and charging circuit excuse to charge.All must dispose the charger of a special use when but the electronic product of almost all kinds such as mobile phone etc. dispatch from the factory at present, because the charger on the market is multifarious, so cause charging inconvenient.If particularly a people has a plurality of mobile phones, must carry a plurality of chargers, bring great burden to travelling.Though present universal charger can be realized the compatibility charging to many moneys battery; But need from electronic product, take out battery; Not only trouble also can be because of short of electricity causes losing of some electronic product data on file, and generally can only support a battery is charged.
The charging field that the present wireless charger that occurs is introduced electronic product with the electromagnetic induction technology, through electricity-magnetic, magnetic-electricity conversion has been realized the nothing electric shock charging of mobile phone, its core technology is similar to the centreless processing of transformer.This wireless charging mode will be rewritten traditional electronic product charging modes, when charging, as long as be put into electronic product to be charged on the charging radiological unit.And can accomplish the unification of all electronic product charging modes not receive the restriction of any brand and model, a shared charger just, and a plurality of electronic product charges simultaneously.The up-to-date more traditional charger of wireless charger has had advantages such as current stabilization, charging interval weak point at present, and because its wireless, contactless characteristics, so safe.If the mobile phone of all brands all adopts the charger of this standard, so global mobile phone manufacturer just need not dispose charger, and each subscriber household is as long as a charger just can satisfy the charging requirement of mobile phone in the family fully.This can economize on resources greatly, reduces the discharge capacity of carbon, satisfies the demand for development of low-carbon (LC).
Yet under the trend of current consumer electronics slimming, miniaturization, the electronic product inner space is more and more littler.And the receiver of wireless charger just seems very important in the inner layout of electronic product, simultaneously because coil is contained in receiver inside, so than other assembly that is easier to disturb electronic product inner, how laying this receiver becomes stubborn problem.Present way is that the receiver coil periphery is provided with the magnet steel housing, makes the radiation to the outside of coil obtain very big decay.But this will further tie up the inner space that this has been of great value of electronic product.In addition, the inner requisite loud speaker of electronic product is also often because volume has certain interference more greatly, to external world, and its riding position also usually requires careful consideration.
Summary of the invention
The objective of the invention is deficiency in view of prior art; Propose a kind of pointedly and the integrated wireless charging receiving terminal of loud speaker; Can the loudspeaker assembly and the wireless charging receiving terminal assembly of electronic product be integrated; Significantly improve space availability ratio, and reduce of the interference of these two assemblies other assembly.
The technical scheme that the present invention adopts is:
Comprise loam cake, lower cover, lower cover bossing, cone, top flat, voice coil loudspeaker voice coil, magnet, coil on this receiving terminal structure, be divided into speaker portion and wireless charging receiver part.Loam cake and lower cover play effects such as protection, fixing and radiation-screening to integral body.
Said speaker portion has 3 kinds of versions:
Version one is: the lower cover center is provided with groove, and magnet places in the groove, and top flat, cone are installed on the magnet successively, and voice coil loudspeaker voice coil is set on the magnet, and bonds together with cone;
Version two is: the lower cover center is provided with groove, and soft iron is arranged in the groove, and the magnet of annular is placed in outside the soft iron, and top flat places on the magnet, and cone places on the soft iron, and voice coil loudspeaker voice coil is set on the soft iron, and bonds together with cone; Perhaps magnet is arranged in the groove, the soft iron of annular is placed in outside the magnet, and top flat places on the soft iron, and cone places on the magnet, and voice coil loudspeaker voice coil is set on the magnet, and bonds together with cone;
Version three is: the lower cover center is provided with groove; Inner ring magnet places in the groove, and outer ring magnet is set in outside the inner ring magnet, sets gradually top flat and cone respectively on outer ring magnet and the inner ring magnet; Voice coil loudspeaker voice coil is set on the inner ring magnet, and bonds together with cone;
Whole speaker portion is fixed between loam cake and the lower cover; Up-down vibration can take place in the logical alternating current of going up of voice coil loudspeaker voice coil under the action of a magnetic field that magnet provides, and then drives and its coherent cone vibration, thereby promotes the surrounding air vibration, sounds;
The structure of wireless charging receiver part is: the lower cover position of speaker portion dorsad is provided with the lower cover bossing, and mounting coil is on the lower cover bossing.Coil is used to respond to the electromagnetic wave signal of external wireless charging dispensing device.
Said lower cover bossing is cylindric, flat column or polygon post shapes.
In the third version of said speaker portion, the polarity of outer ring magnet and inner ring magnet is opposite.
Beneficial effect of the present invention is:
This structure integrates loudspeaker assembly and wireless charging receiving terminal assembly, significantly improves space availability ratio, and reduces the interference of these two assemblies to other assembly of electronic product inside; Simple in structure, cost is low, volume is little, low-carbon environment-friendly, has the market competitiveness.
