Abstract
The invention provides a circuit board, comprising an induction coil, a sound source signal wire and a ground wire, wherein the induction coil and the sound source signal wire are respectively arranged at two sides of the ground wire; the ground wire separates the induction coil with the sound source signal wire at a predetermined distance; and the predetermined distance is at least the induction distance of the induction coil. Because the ground wire which is used for separating the induction coil with the sound source signal wire at the predetermined distance is paved between the induction coil and the sound source signal wire, the mutual interference between the induction coil and the sound source signal wire is excluded, so that the induction coil and the sound source signal wire are paved on the same circuit board, thereby avoiding the trouble of increasing the cost caused by paving the induction coil and the sound source signal wire on different circuit boards.
Description
Technical field
The present invention relates to a kind of circuit board.
Background technology
The capacitance key of existing electronic equipment and sound source meeting mutual interference mutually, thereby all be that sound source wire and capacitance key are placed in different flexible circuit boards to avoid interference generally.So, this kind mode needs two flexible circuit boards, thereby has increased the volume and the cost of electronic equipment.
Summary of the invention
In view of this, be necessary to provide a kind of volume relatively little, lower-cost circuit board, to address the above problem.
A kind of circuit board, it comprises induction coil, sound source signal line and ground wire.The be placed in both sides of described ground wire of described induction coil and described sound source signal line.Described ground wire separates a preset distance with described induction coil and described sound source signal line, and described preset distance is at least the distance of reaction of described induction coil.
Circuit board of the present invention separates the ground wire of a preset distance owing to laid one between induction coil and sound source signal line with induction coil and sound source signal line, got rid of the phase mutual interference between induction coil and the sound source signal line, thereby induction coil and sound source signal line can be layed on the same circuit board, avoid induction coil and sound source signal line are layed in the trouble that increases cost on the various boards.
Description of drawings
Fig. 1 is the stereogram of circuit board in the execution mode.
Fig. 2 is the exploded view of circuit board among Fig. 1.
The main element symbol description
Sound source signal line 20
Embodiment
See also Fig. 1, it is the stereogram of the circuit board 100 of an embodiment of the present invention.In the present embodiment, circuit board 100 is a flexible circuit board, and it is used to have the electronic equipment of capacitance key, as mobile phone, e-book etc.
Please in the lump with reference to figure 2, circuit board 100 comprise capacitance key induction coil 10, the sound source signal line 20 below the induction coil 10 and be located at induction coil 10 and sound source signal line 20 between ground wire 30.
Preferably, the width W of ground wire 30=distance of reaction S * 1.5.Wherein, distance of reaction S is the actual induction distance of induction coil 10, and promptly in this distance of reaction S, induction coil 10 can be sensed interference signal.In other words, if interference source, as the sound source signal line 20 in the present embodiment, and the distance between this induction coil 10 is less than distance of reaction S, and then interference source can produce this induction coil 10 and disturb.Therefore, present embodiment preferably adopts width W=distance of reaction S * 1.5 of ground wire 30, make the distance between induction coil 10 and the sound source signal line 20 be at least 1.5 times distance of reaction S, thereby guarantee that this induction coil 10 can not be subjected to the interference of this sound source signal line 20.
When adopting circuit board 100 of the present invention, owing between induction coil 10 and sound source signal line 20, laid one induction coil and sound source signal line separated the ground wire 30 of a preset distance, got rid of the phase mutual interference between induction coil 10 and the sound source signal line 20, thereby induction coil 10 and sound source signal line 20 can be layed on the same circuit board 100, avoid induction coil 10 and sound source signal line 20 are layed in the trouble that increases cost on the various boards.
Those skilled in the art will be appreciated that; above execution mode only is to be used for illustrating the present invention; and be not to be used as limitation of the invention; as long as within connotation scope of the present invention, appropriate change and the variation that above embodiment did all dropped within the scope of protection of present invention.
