Description
The utility model relates to a kind of glasses, particularly a kind of multi-functional glasses.
Chinese patent CN2059994U, 89202884.X have announced a kind of multifunctional glasses rack, glasses, are a kind of can the focusing with slide bar, and picture frame can overturn, not press the glasses of the bridge of the nose, are suitable for the big people of activity and the elderly's use.But do not have radio reception, flash of light to warn and the function of hearing aid, still do not satisfy people's needs, particularly for the elderly or the people who is thick of hearing, inconvenience in addition.
The purpose of this utility model be to provide a kind of can radio reception, the multi-functional glasses of hearing aid and audio frequency flash of light, for people's life, study, amusement and information transmission brings more convenience.
The utility model is achieved in that button cell, standby power supply jack, power switch, flashing switch etc. is housed on the left leg of spectacle frame, passes the glasses crossbeam with lead, to the radio reception main frame power supply of the right leg that is contained in spectacle frame.The frequent main frame of operation is contained in the right leg of spectacle frame, be for majority with the cause of the right hand than left hand dexterity, certainly, also can be as required, the installation site of main frame and power supply is swapped left and right.
End at spectacle frame two legs is equipped with micro earphone, inserts the duct audition.Micro earphone fixes with parbuckle screw, adjusting steel disc and spring, and its distance, angle and compaction degree can carry out flexible according to each one shape of face size.Also the earplug lead-in wire can be wrapped on the leg of spectacles of the right and left, according to each one the duct distance and the number of turns of angle decision winding.
Deaf-aid set is the middle part that is contained in the spectacle frame crossbeam, adopt electret capacitor microphone (MIC) inspection sound, the sound signal that MIC picks up is delivered to the integrated circuit power-amplifier stage by switch and is carried out power amplifier after one-level is amplified, pass to earplug again and send loud and clear sound, reach the purpose of hearing aid.
The audio frequency light emitting diode be contained in glasses about angle on two.It is to utilize the tone currents after the power amplification to drive, and it flashes, and the power that is with signal changes, and it is a signal meter (SM), is again to recruit eye-catching and warn sign night.The time spent does not close flashing switch and gets final product.
For realizing complicated superheterodyne microminiaturization, to be convenient to be contained on the spectacle frame, the utility model has been taked special measure:
1, the input circuit of this machine can not adopt common bar magnet, coil, because its volume is obviously too big for the utility model.Therefore, designed the distinctive input circuit of this machine, promptly at superhet syntonizing coil B
1The front has increased one-level untuned frequency modulation and has amplified (seeing accompanying drawing 1).This syntonizing coil B
1Undertaking dual role tuning and high frequency amplification load (high-frequency transformer),, taking certain shielding quarantine measures for preventing high frequency interference.
2, the untuned high frequency amplifies.BG
1Be high frequency amplifier tube, external antenna is imported BG with the high-frequency signal that receives from coupling capacitance Cc
1Base stage is carried out the untuned high frequency and is amplified, and exports high-frequency transformer to through collector, i.e. syntonizing coil B
1, become intermediate-freuqncy signal through tuning after selecting required high-frequency signal and local oscillation frequency mixing, so far just finished superhet radio reception frequency conversion task.As this syntonizing coil B
1Be tuned to during with required frequency resonance, be exactly that this frequency is amplified resulting maximum output through high frequency.
3, the high exoergic of the untuned sensitivity that improves this machine effectively; But can not improve selectivity.In order to improve the selectivity of this machine, take in put in the level and to use ceramic filter ZL465 to replace the intermediate frequency shunt capacitance, like this, can only allow intermediate frequency (465KHz) signal after frequency conversion pass through, all the other signal attenuations, thereby improve the selectivity of this machine.
4, human body antenna.The untuned high frequency amplifies external antenna, yet obviously can not erect a television antenna on spectacle frame, proves that through inventor's test of many times itself can be used as antenna human body.This machine spectacle frame and bridge of the nose contact point promptly are the contacts of human body antenna.
5, in order to realize the microminiaturization of this machine, taked to make special small-sized I.F.T., the inductance element of these three keys of syntonizing coil and oscillator coil, its physical dimension is less than φ 7 * 5.5mm, make this machine chip be thinned to 6mm, realized that superheterodyne with complexity is contained in the purpose on the spectacle frame.
6, take special shielding measure.The miniaturization of this machine of realization, the shielding of each inductance component should not be taked common metal cage.It is when compacting cabinet (leg of spectacles) that the shielding of this machine is isolated, and just leaves the slotted eye of described inductance element in advance, and at the inwall coated conductive metal layer of slotted eye, unified then ground connection is handled, and this machine is to connect positive electrode, reaches the purpose of shielding.
In addition, each Resistor-Capacitor Unit all adopts micro parts.
This machine performance index are: frequency range 535～1605KHz, and sensitivity 0.1mv/m, selectivity＞30dB, harmonic distortion rate 2% is about quiescent current 2mA; Rated power 100mW.Meet or exceed the A grade standard.But must point out that these indexs depend on the quality of used integrated circuit block to a great extent.
This machine uses daily output integrated circuit TA7641BP, can be directly with daily output TA7641, TA7641AP replacement, or with replacement such as homemade integrated circuit FX7641, FY7641, TB7641, XG7641, also can adopt other integrated circuit, as ULN2204, ULN3839, TA7613 etc., but circuit needs suitably to change.
The utility model is owing to take above-mentioned technical measures, successfully radio reception, hearing aid, audio frequency flasher are contained on the spectacle frame, realized on a spectacle frame, can carrying out multi-functional effects such as radio reception, hearing aid, audio frequency flash of light as required, easy to carry, handsome in appearance, satisfied people's life, study, the needs of amusement.
Further specify formation of the present utility model with embodiment below.
