Avoid support element that from there must be any opening.According to the present invention, wireless charger includes at least one induction coil 10.Coil must
It must be smaller so that it may be mounted in support element.In order to realize that this point, the track on printed circuit board (PCB) 11 serve as induction
Coil.Therefore coil is flat, is formed by circuit orbit.According to the present invention, each coil has been adapted to allow RF
Both the radio wave of module and a part for induction field pass freely through (that is, not interfering with), and to allow, there are other lines
Circle is without resonance effects.About the conventional coil shown by left side in Fig. 3, coil 10 according to the present invention includes turn-to-turn space

Induction coil 10.Coil can be superimposed and be formed by the track on the different layers of printed circuit board or positioned side by side.By line
It is also possible that the vertical horizontal arrangement arranged with coil of circle, which is combined,.In this configuration with multiple coils, sense
What should be able to be measured does not pass through the first coil by the part that first coil captures and induces electric current in the second coil, with
This analogizes.Therefore, energy loss reduces, so that saving capacitance while keeping identical efficiency or reducing support element
Size be possibly realized.Due to especially important in the present case in terms of size, so the reduction of size is advantageous.
In the case of multiple coils, the number of turns can be reduced, it means that diameter D3 can decrease below the value of 15mm.Due to this
The diameter that kind reduces, therefore the width of support element can reduce.The thickness E of coil can also decrease below 105 μm of value, with
Just coil can be located in the internal layer of printed circuit board.However, other dimensions of coil are similar.About between coil
Space, the order of magnitude with 0.5mm.Will be specified, ferrite may be needed between coil and the rest part of system

Include at least two concatenated capacitors 12 and battery 13 according to the present invention, storage and for electric installation (referring to Fig. 2).With at least
This configuration of two capacitors is due to the fact that and favored.Must very little to adapt to the space interior in support element
Monoblock battery does not have enough power that motor is made to reach maximum performance when being used alone, even if technically being deposited after recharging
In enough energy.Add single capacitor is also to accumulate the energy started needed for motor (it needs a large amount of instantaneous energy)
It can not imagine.Specifically, in order to start powerful motor, need longer time recharged and occupied space it is big
The support element of capacitor, the capacitor and small size is incompatible.
Therefore, the particular power source using at least two concatenated capacitors is devised, to drive for circuit and battery
Size for generally too powerful motor.First quick charge capacitor device pair, second capacitor charges.At this
Alternating between two capacitors makes it possible to electric current being continuously provided to motor, be isolated by the rotating weight of vibrating motor
Therefore adverse current caused by mechanical resistance simultaneously saves required gross energy.
In order to enhance the vibration that user is experienced, pulse is applied to motor and is advantageous, that is, by rapidly to motor
ON/OFF/ON/OFF applies pulse to apply vibration.To achieve it, using two or even three capacitors are very heavy
It wants, because motor constantly restarts, wanders back to, this needs a large amount of instantaneous energy.Applying pulse to motor allows to increase
The impact force of big motor because motor is unstable and therefore has an impact by a larger margin at the start, once and it
When running, the inertia of motor and the relative equilibrium reached due to rotational stabilization then reduce vibration amplitude and because
This feeling experienced.
When using two motors, it is important that the two motors cannot rotate simultaneously, because if a such as weight
Positioned at 0 degree of position and when another is located at opposite location, i.e. 180 degree, weight may cancel out each other.Therefore, the two motors
It engages one by one, preferably vibrates entire support element.In order to maintain these pulses, for two motors, have
The circuit of two, three or even four capacitors is necessary.
Will be specified, instead of vibrating motor, it is possible to it is contemplated that " too " high powers such as type buzzer
Sound buzzer implements the above-mentioned device for powering to the high power sound buzzer, the high power sound when applying pulse
