Plate 10 is located at the side of charger 11, and dynamic iron 12 is located at the side of charger 11, and microphone element 13 is located at the surface of charger 11.
In the present embodiment, touch screen plate 6 is arranged in the outermost of bluetooth headset, when bluetooth headset is inserted into ear
When, touch screen plate 6 stays in outermost, convenient for users to touch and control, the area setting of touch tablet is smaller, on the one hand cooperates blue
The shell of tooth earphone do to the volume of entire bluetooth headset small, on the other hand avoids the excessive shadow of individual 6 area of touch screen plate
Ring the beauty for arriving bluetooth headset.
In the present embodiment, when assembling, mainboard 10 is plugged on the card slot inside front cover 4 first, then by dynamic iron
12 are mounted at the acoustic aperture 3 out of front cover 4, are attached with mainboard 10, the touch tablet of touchscreen element and front cover 4 is attached solid
It is fixed, and electric wire connection is carried out with mainboard 10, antenna is fixed at 5 position of antenna plate, and is connected with mainboard 10, microphone element 13
It is fixed at microphone hole 8, while being also attached with mainboard 10, then place charger 11 and battery by the one of mainboard 10
Side, and it is located at the top of microphone element 13 and antenna, rear cover 1 is finally subjected to grafting by the contact pin 9 to hole post 2 in front cover 4,
So that rear cover 1 and front cover 4 carry out lid conjunction, complete bluetooth headset is formed, when wearing, hand-hold Bluetooth earphone is by front cover 4 towards face
Before, rear cover 1 towards hindbrain at, it is filled in ear slowly then and is worn.
And by part of and back-cover 5 touch screen face 9, antenna surface 10, microphone hole 811 and second go out between acoustic aperture 37
The corresponding of position is carried out, then the contact pin 96 in back-cover 5 is inserted into the spliced eye 3 of front case 1, thus to internal member
Device is installed, and complete bluetooth headset is formed, and then by front case 1 to after brain, back-cover 5 laterally goes out first in front
Acoustic aperture 34 and second go out acoustic aperture 37 be inserted into the external auditory canal of user, the cambered surface 2 of front case 1 is completely pasted with external auditory canal
It closes, guarantees to use comfortable.
Further, front cover 4 is arranged in far from the one end for going out acoustic aperture 3 in microphone hole 8, and microphone hole 8 is located at the back of front cover 4
Face.
In the present embodiment, front cover 4 is arranged in far from the one end for going out acoustic aperture 3, when front cover 4 and 1 group of rear cover in microphone hole 8
When at bluetooth headset shell, and 3 one end of acoustic aperture will be gone out when being inserted into ear, microphone hole 8 due to far from the one end for going out acoustic aperture 3,
It is left on the outside of ear, the reception of more convenient pair of external sound, while also avoiding with acoustic aperture 3 out too closely, receiving and speaking
Sound after the sending of hole 3, causes the mixed and disorderly of sound.
Further, the receiving end of microphone element 13 is adapted with microphone hole 8, and microphone element 13 is located at microphone hole 8
Inside.
In the present embodiment, the receiving end of microphone element 13 is subjected to corresponding, the reception of microphone element 13 with microphone hole 8
End is connected by microphone hole 8 with external environment, and for receiving the sound in external environment, the voice that user issues is believed
Breath is collected and forwards.
Further, microphone element 13 is welded in the inner surface of front cover 4.
In the present embodiment, microphone element 13 is set as 4013 patch microphones, inside microphone element 13 there are one by
Vibrating diaphragm, the capacitor of gasket and pole plate composition, because filled with charge on diaphragm, and is a plastic foil, thus when diaphragm by
To the effect of sound pressure, diaphragm will generate vibration, so that the distance between diaphragm and pole plate are changed, to change capacitor
The distance between two pole plates produce the variation of a Δ d, therefore by formula C=ε S/4 π kd it is found that one must be generated
The variation of a Δ C, is known again by formula C=Q/V, and due to the variation of Δ C, charging charge is fixed and invariable again, therefore is necessarily produced
The variation of a raw Δ V, tentatively completes a conversion by acoustical signal to electric signal in this way；Since this signal is very micro-
Weak, internal resistance is very high, cannot directly use, therefore also to carry out impedance transformation and amplification, and FET field-effect tube is a voltage control
Element processed, drain electrode export electric current by the control of source electrode and grid voltage, since two poles of capacitor are the pole S for being connected to FET
With the pole G, as soon as therefore be equivalent between the pole S of FET and the pole G and added a variable quantity of Δ v, the drain current I of FET generates one
The variable quantity of a Δ ID, therefore the variable quantity of this electric current just generates the variable quantity of a Δ VD, this voltage on resistance RL
Variable quantity can be exported by capacitor C0, the variable quantity of this voltage is as caused by acoustic pressure, therefore entire microphone is with regard to complete
At the conversion process of an acoustic-electric.
Further, microphone hole 8 is in capsule shape, and each side is respectively 4.9400mm；2.3600mm；0.3299mm；Corner
Radius is 1.2900mm.
In the present embodiment, the shape to microphone hole 8 and each edge lengths and knuckle radius are defined, and are avoided entire
Microphone hole 8 is excessive in the setting of the back side of front cover 4, influences the setting of remaining element, causes entire 4 appearance of front cover unsightly.
Further, rear cover 1 and front cover 4 form bluetooth headset shell, and are inserted into ear close to the one end for going out acoustic aperture 3.
In the present embodiment, rear cover 1 and front cover 4 form bluetooth headset shell, for various inside bluetooth headset
Electric elements are protected, and avoid being damaged, and on the other hand in order to be adapted to the external auditory canal of human body, guarantee the comfort level worn.
Further, the inside of front cover 4 also contains antenna, and antenna, charger 11, dynamic iron 12 and microphone element 13 are equal
It is electrically connected with mainboard 10.
In the present embodiment, it is antenna that the inside of the antenna plate 5 of front cover 4 is corresponding, and antenna is connected with mainboard 10, mainboard
10 are connected with battery, and battery and wireless charger 11 are wholely set, the touchscreen element also corresponding with touch screen plate 6 of mainboard 10,
The corresponding microphone element 13 in the microphone hole 8 and corresponding sounding component of acoustic aperture 3 is connected out, when charging, external wireless charging dress
It sets and wireless charging is carried out to internal wireless charger 11, so that carrying out charging to battery guarantees normally making for bluetooth headset
With in use, being attached with external bluetooth, bluetooth by touchscreen element control mainboard 10 to antenna progress signal control
After successful connection, antenna feeds back to mainboard 10 after receiving the signal of mobile phone or computer, and mainboard 10 controls internal sounding
Element carries out sounding, while microphone element 13 receives extraneous sound and is sent to mainboard 10, by antenna be sent to mobile phone or
The transmission of the progress voice such as laptop.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
