Because rechargeable button cell capacitance is very little, need every day and take out one to charging for several times, more bother in the use, and usually the battery door of folding battery case is easy to cause battery door to damage, the tool statistics, about 40% hearing aids maintenance work all is to change battery door.
The utility model is a kind of external cell supply that develops at using the button cell hearing aids, and especially provides in order to replace button cell, and provide a kind of electric weight is seen through the external cell supply that hearing aids is given in the electric wire supply.
Summary of the invention
Main purpose of the present utility model provides the external power source supply that a kind of hearing aids is used.This external power source supply include one be positioned at hearing aids just reach negative supply contact, an electric wire and a power supply unit.Power supply contact uses two thin slices that connect electric wire, and this electric wire needn't be revised the hearing aids structure can pass battery case.At the electric wire other end is power supply unit, can be the combination of solar cell and storage battery, or general compact battery.Multifunction power supply includes one provides conducting channel, automatically loud noise control circuit, but to detect background noise volume when noise reaches overload automatic pause end, and return the normal level value in background noise volume and can open automatically; And a voltage stabilizing circuit, remain on 1.4V with control output voltage.
This external power source supply includes:
One is just reaching the negative supply contact, and size also made according to the button cell size that hearing aids is used, and it includes two metallic conduction lamellar bodies, to be connected with electric wire; And
One power supply unit is by being wired to above-mentioned contact.
The above-mentioned negative supply contact that just reaches is to be placed in the hearing aids battery case.
Two above-mentioned metallic conduction lamellar bodies pass the space between hearing aids housing and battery case.
Above-mentioned external power source supply further includes one can detect background noise volume, but and when noise transships automatic pause end the automatically loud noise control circuit that can open automatically when making background noise volume return the normal level value.
Above-mentioned button cell is the button cell that battery the 675th, 13,312,10 or the 5th is numbered one of them.
The utility model is a kind of external cell supply that develops at using the button cell hearing aids, and especially in order to replace button cell, and provides a kind of external cell supply that electric weight is given hearing aids by the electric wire supply.This external power source supply comprises one group of automatically loud noise control circuit, and it can detect background noise volume.Power supply unit be as can temporarily stopping when noise transships, in case and background noise volume starts when returning the normal level value more automatically, with protection hearing aids user's hearing and save button cell consumption.

Embodiment
See also Fig. 1, the utility model comprise be positioned at hearing aids just reach negative supply contact 1, power supply unit 2 and an electric wire 3.
Basically, the model class of power supply contact is similar to button cell, and its size is also according to button cell that hearing aids uses (as battery numbering 675,13,312,10 and 5 or the like) size made.
As shown in Figure 2, power supply contact has a positive electrode metal-back 101; What electric wire 3 one ends were connected to power supply unit 2 just reaches negative output terminal, and the other end then is connected to metallic conduction sheet 106 (positive pole) and 107 (negative poles) respectively.This two metallic conductions sheet position is on PVC plastic cement 108 and only expose suitable length.This two metallic conductions sheet inserts metal-back 101.Metallic conduction sheet 107 is with screw 103 and plastic cement lamellar body 104 and 105 lockings of negative supply contact, for the negative conductance with power supply unit 2 causes negative supply contact 105.One insulating washer 102 is positioned over that positive electrode shell 101 is used for covering all component on the screw 103; Along with the plurality of through holes that screw 109 passes metal-back 101, conducting strip 106 and insulation spacer 102,, can not unclamp because of pullling to guarantee conducting strip 106 closely to screw togather to plastic cement lamellar body 104.
At last by anchor clamps pressing positive electrode 101 openings and plastic cement lamellar body 104, to finish the structure that just reaches negative supply contact 1.
See also Fig. 3 as for power supply unit 2.In graphic, electric wire 3 connecting circuit plates 206, negative conductive electric wire then is connected to battery spring 211.Solar cell 201 is closely filled in the plastic cement shell 202, and this electric wire passes plastic cement shell 202 and is connected to the power input of circuit board 206.Storage battery 205 is welded on the bottom surface of circuit board 206.Circuit board 206 is positioned in the plastic cement shell 203, electric wire 3 then the position at the side of two plastic cement shells 202,203.This two plastic cement shell the 202, the 203rd sticks together together again.When using general battery 209, battery is arranged on plastic cement shell 203 bottom surface opening parts, and between battery spring 210,211, closed more afterwards battery case 204.
Seeing also Fig. 4, is the electrical structure of power supply unit.In circuit board 206, there is a power supply to open/make and break pass 208, to select solar cell, regular battery or shutdown.Circuit board comprises a power charging circuit 206a (output voltage of adjusting solar cell to avoid be short-circuited) when using storage battery, one automatically loud noise control circuit 206b (uses a microphone 207 to obtain the background noise, calculate volume and control noise and be lower than 84dB, to stop and/or power-on supply again), and a regulating circuit 206c (voltage setting circuit and a pressurizer, in order to promote storage battery 205 (1.2V) and/or regular battery 209 (1.5V) voltage to 1.8V, regulate electric wire 3 power supplys afterwards again to 1.4V, and export contact 1 to).
The consumer will insert the top of power supply contact 1 to battery case 4 (shown in Fig. 5 b) shown in Fig. 5 a, so two spaces that metallic conduction lamellar body 106,107 can pass between hearing aids housing and battery case, again and close battery case, he or she can bring into use hearing aids then.Power supply unit can be clipped in collar, sleeve or clothes front, to avoid clipping to electric wire.
Conclusion; the utility model is a kind of external power source supply that is used for hearing aids; not only can be converted to storage battery with having regular battery now; also can be when the background noise transships the temporary close power supply unit; and when returning the normal level value, background noise volume starts automatically again, with protection user's hearing.The utility model is an original new product really.
