Embodiment
Core concept of the present invention is: between the loudspeaker of the product with people's ear measuring ability and mainboard, increase metal clips; Make the shell foot of metal clips contact with the metal shell of loudspeaker; Making metal clips pass through connecting line is connected with the capacitance detecting interface of mainboard; During when human body contact or near loudspeaker, mainboard detects the variation of capacitance through said capacitance detecting interface, starts corresponding function.
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.
Embodiment one is applied to this human ear detection method in a kind of bluetooth earphone, and specific embodiments is following:
Fig. 1 is the flow chart of the bluetooth earphone human ear detection method in the embodiment of the invention one.As shown in Figure 1, this method comprises:
In embodiments of the invention one, can also on the loudspeaker of bluetooth earphone, overlap a seal rubber sleeve, be used for realizing the sealing in sound chamber, bluetooth earphone loudspeaker front and back.This seal rubber sleeve is provided with the breach of avoiding the metal clips shell foot, is called here to keep away a breach.
Metal clips can have more than one shell foot, then in step 102, makes the more than one shell foot of metal clips contact with the metal shell of loudspeaker.And the shell foot of metal clips has formed a touch electrode with after loudspeaker link to each other, and during when the human body contact or near touch electrode, human body and touch electrode have formed human body sensing electric capacity.
In step 103, the capacitance detecting interface is meant and is installed on the mainboard, can detect the I/O mouth of the capacitance detecting chip that the capacitance of electric capacity changes.
In an embodiment of the present invention, the effect of metal clips is the area of detection that increases electrode, and it is obvious more to make the I/O mouth of capacitance detecting chip detect the change of capacitance, and then people's ear measuring ability sensitivity of bluetooth earphone is uprised, and consistency improves.Its principle is because the size of electric capacity is relevant with the area of electrode; After adding metal clips; Increased the area of touch electrode, and then increased the area of detection of electrode, it is obvious more to make the I/O mouth of capacitance detecting chip detect the change of capacitance; Thereby people's ear measuring ability sensitivity of bluetooth earphone is uprised, and consistency improves.
So-called sensitivity is meant the sensitivity of the product people ear measuring ability with people's ear measuring ability.
After people's ear was worn earphone, under capacitance changed unconspicuous situation, the I/O mouth of electric capacity detection chip can detect people's ear sometimes and wear earphone on the mainboard, can not detect people's ear sometimes and wear earphone, had promptly produced the low problem of consistency.So-called consistency is meant that the I/O mouth of capacitance detecting chip can reflection people ear promptly and accurately wears the situation of earphone, and whether decision mainboard promptly and accurately starts corresponding function.
