Specific embodiment
To describe the utility model in detail below with reference to accompanying drawing and in conjunction with the embodiments.It should be noted that not rushing
In the case of prominent, the embodiment in the application and the feature in embodiment can be mutually combined.
Additionally provide a kind of headphone in the present embodiment.Fig. 1 is the wear-type according to the utility model embodiment
The top view of earphone, as shown in figure 1, this headphone includes：Left earphone 1, right earphone 2 and connect left earphone and right earphone
Head beam 3, wherein, is provided with receiving coil 4, wherein, receiving coil is electrically connected with charging control circuit, rechargeable battery, fills in head beam 3
Electric control circuit and rechargeable battery are arranged on inside left earphone and/or right earphone, not shown in figure.
Using the headphone with wireless charging device (i.e. receiving coil, charging control circuit and rechargeable battery),
It is no longer necessary to wired charging wire or wired charging line interface are designed on earphone, the charging wire solving earphone is easily wound around
The problem depositing inconvenience being led to, improves user experience.
In the present embodiment, wireless charging technology adopts electromagnetic induction principle.Electromagnetic induction phenomenon refers to be placed on change magnetic flux
Conductor in amount, can produce electromotive force.If this conductor is the loop of one section of closure, induced-current can be formed in the conductor.
The realization of wireless charging needs two parts：Transmitting terminal and receiving terminal.Respectively there is a coil in transmitting terminal and receiving terminal.This enforcement
In example, send end-coil and can be integrated on charging panel (charging holder), receive end-coil and be integrated on earphone.When electric current passes through
After transmit coil, magnetic field will be produced, the receiving coil in earphone, because the effect of electromagnetic induction, can form induced electromotive force
And form induced-current it is possible to charge to earphone.More preferably, the distance between transmitting terminal and receiving terminal are less than 10mm, therefore
Need during charging earphone is placed on charging panel (charging holder).The operating frequency of the wireless charger of earphone be 100～
210KHZ, operating current is 0.5～1.4A, and its charge efficiency can reach 84%.
During wireless charging system work, first alternating current is converted into direct current by rectification circuit, then is produced by driver
Raw frequency is supplied to transmit coil in the alternating current of 100～210KHZ.As shown in Figure 2.
By electromagnetic induction, receive end-coil and produce induced-current.After radio source receiver receives electric current, by filling
The electric loop just can charge the battery.The electricity of battery can provide stable electricity by PMU to whole system
Source.Its system schematic is as shown in Figure 3.
Alternatively, the shape of receiving coil is identical with the contour shape of left earphone or right earphone.
Alternatively, the orthographic projection shape of receiving coil includes but is not limited to one below：Triangle, quadrangle, pentagon,
Hexagon, circular, ellipse.More preferably, the orthographic projection of receiving coil is shaped as quadrangle, hexagon or ellipse.?
The schematic diagram of circular coil and polygonal coil is shown in Fig. 4.
The charging holder that the headphone of the present embodiment uses can be general wireless charging deck or be somebody's turn to do
The special charging holder of headphone.Alternatively, headphone also includes a kind of matching used charging bracket (wireless charging
Electric card seat), charging bracket is provided with the transmit coil being electrically connected to each other, charging control circuit and power input interface.Power input
Interface is used for electrically connecting with city, or electrically connects with city through transformation system.
Alternatively, charging bracket includes：Support base 5, support bar 6 and earphone pallet 7, wherein, the top of support bar 6 with
Earphone pallet 7 bottom connects, and the bottom of support bar 6 is connected with the top of support base 5, and transmit coil 8 is arranged on earphone pallet 7
Top, the charging control circuit being electrically connected with transmit coil and power input interface are arranged on inside support base 5.As Fig. 5 institute
Show.
Alternatively, the top of earphone pallet is channel-shaped curved surface, and this channel-shaped curved surface is identical with the curvature of earphone heads beam or near
Like so that keeping grade spacing between earphone heads beam and earphone pallet.
When charging bracket charges, need the head beam close contact charging therewith of earphone.Distance is bigger, and charge efficiency is therewith
Reduce.Electromagnetic induction schematic diagram between them is as shown in Figure 6.Need during charging that two coils are almost parallel, close contact,
Earphone receiving coil side is placed on earphone pallet.
Alternatively, alternatively, the top both sides of earphone pallet are additionally provided with buckle, and buckle is used for be provided with receiving coil
Head beam is fixed on earphone pallet.
