Abstract
The utility model discloses a hearing aid, including not gate F1, not gate F2, microphone Y, resistance R1 and triode VT1. The utility model discloses hearing aid has sensitivity height, power consumptive few, small in size, outstanding advantage that weight is very light, and especially adapted deaf person uses, and hearing aid uses one piece of 3V button cell to make the power, listens to with 8 ordinary omega earphones, and sound clearly becomes clear, the low price, and stability is very high.
Description
Technical field
The utility model relates to medical field, specifically a kind of hearing aids.
Background technology
Along with the development of science and technology, the function of hearing aids gets more and more, and becomes better and better, also more and more expensive, and the hearing aids of low side all exists the problems such as lower tone, reception is bad, volume is large, power consumption is large.
Utility model content
The purpose of this utility model is to provide a kind of hearing aids of highly sensitive, little power consumption, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of hearing aids, comprise not gate F1, not gate F2, microphone Y, resistance R1 and triode VT1, described microphone Y one end is contact resistance R1 and electric capacity C1 respectively, resistance R1 other end frames connecting with headphone socket B pin 2, receiver J-Horner B pin 1 connects battery E positive pole, battery E negative pole is connecting triode VT1 collector electrode respectively, resistance R4, resistance R5, resistance R6 and the microphone Y other end, triode VT1 emitter frames connecting with headphone socket B pin 3, triode VT1 base stage is the contact resistance R4 other end and electric capacity C2 respectively, the electric capacity C2 other end is contact resistance R3 and not gate F3 output respectively, not gate F3 input is the contact resistance R5 other end and not gate F2 output respectively, not gate F2 input is the contact resistance R6 other end and not gate F1 output respectively, not gate F1 input is the contact resistance R3 other end respectively, potentiometer RP and potentiometer RP slide plate, the potentiometer RP other end contact resistance R2 other end.
As further program of the utility model: described battery E is 3V button cell.
As the utility model further scheme: described receiver J-Horner B power output is 8W.
Compared with prior art, the beneficial effects of the utility model are: the utility model hearing aids has that highly sensitive, power consumption is few, the outstanding advantages of compact, very light in weight, be applicable to very much deaf person to use, hearing aids uses one piece of 3V button cell to make power supply, listen to common 8 Ω earphones, clear sound becomes clear, and low price, stability is very high.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of hearing aids.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of hearing aids, comprise not gate F1, not gate F2, microphone Y, resistance R1 and triode VT1, microphone Y one end is contact resistance R1 and electric capacity C1 respectively, resistance R1 other end frames connecting with headphone socket B pin 2, receiver J-Horner B pin 1 connects battery E positive pole, battery E negative pole is connecting triode VT1 collector electrode respectively, resistance R4, resistance R5, resistance R6 and the microphone Y other end, triode VT1 emitter frames connecting with headphone socket B pin 3, triode VT1 base stage is the contact resistance R4 other end and electric capacity C2 respectively, the electric capacity C2 other end is contact resistance R3 and not gate F3 output respectively, not gate F3 input is the contact resistance R5 other end and not gate F2 output respectively, not gate F2 input is the contact resistance R6 other end and not gate F1 output respectively, not gate F1 input is the contact resistance R3 other end respectively, potentiometer RP and potentiometer RP slide plate, the potentiometer RP other end contact resistance R2 other end.
Battery E is 3V button cell.
Receiver J-Horner B power output is 8W.
Operation principle of the present utility model is: after not gate F1, F2, F3 series connection, small-signal AC amplifier is formed with resistance R2, resistance R3, potentiometer RP etc., multiplication factor A=R3/ (R2+RP1), regulator potentiometer RP can change multiplication factor, electric capacity C1 is input coupling capacitance, triode VT1 is connected into emitter follower form, the AC signal of amplifier by electric capacity C2 coupling output is amplified, promote common 8 Ω earphones, resistance R4 is the biasing resistor of VT1, and complete machine adopts earphone socket to double as mains switch.When receiver J-Horner B plugged earphone, power supply is connected, and when earphone is extracted, power supply cuts off automatically, simplifies circuit structure, reduces machine volume.
Sound converts the signal of telecommunication to after being received by microphone Y, is coupled to amplifier and carries out voltage amplification, then be coupled to triode VI1 through electric capacity C2 and carry out Current amplifier by electric capacity C1, drives earphone sounding.
