Embodiment
Core concept of the present utility model is: increase metal clips between the loudspeaker of the product with ear detection function and mainboard; Make the shell foot of metal clips contact with the metal shell of loudspeaker; Make metal clips be connected with the capacitance detecting interface of mainboard by connecting line; During when human body contact or near loudspeaker, mainboard detects the variation of capacitance by described capacitance detecting interface, starts corresponding function.
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model execution mode is described in further detail.
Embodiment one is applied to this human ear detection method in a kind of bluetooth earphone, and specific embodiments is as follows:
Fig. 1 is the flow chart of the bluetooth earphone human ear detection method among the utility model embodiment one.As shown in Figure 1, the method comprises:
Step 101 increases metal clips between the loudspeaker of bluetooth earphone and mainboard;
Step 102 makes the shell foot of metal clips contact with the metal shell of loudspeaker;
Step 103 makes metal clips be connected with the capacitance detecting interface of mainboard by connecting line;
Step 104, during when human body contact or near loudspeaker, mainboard detects the variation of capacitance by described capacitance detecting interface, starts Bluetooth function.
In embodiment one of the present utility model, can also at seal rubber sleeve of loudspeaker cover of bluetooth earphone, be used for realizing the sealing in sound chamber, bluetooth earphone loudspeaker front and back.Be provided with the breach of avoiding the metal clips shell foot at this seal rubber sleeve, referred to herein as keeping 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 refers to be installed on the mainboard, the I/O mouth of the capacitance detecting chip that capacitance that can Detection capacitance changes.
In embodiment of the present utility model, the effect of metal clips is the area of detection that increases electrode, and it is more obvious to make the I/O mouth of capacitance detecting chip detect the change of capacitance, and then the ear detection Functional 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 more obvious to make the I/O mouth of capacitance detecting chip detect the change of capacitance, thereby the ear detection Functional Sensitivity of bluetooth earphone is uprised, and consistency improves.
So-called sensitivity refers to have the sensitivity of the product ear detection function of ear detection function.
After people's ear was worn earphone, under capacitance changed unconspicuous situation, the I/O mouth of electric capacity detection chip sometimes can detect people's ear and wear earphone on the mainboard, sometimes can not detect people's ear and wear earphone, had namely produced the low problem of consistency.So-called consistency refers to 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.
