The utility model comprises a housing which is internally provided with an audio frequency transformer; a piezoelectric piece is connected with the audio frequency transformer through a lead; wherein, the audio frequency transformer is connected in parallel with an audio frequency input socket and is further connected with an audio frequency amplifier which is connected with an induction coil and a power; besides, the housing is provided with a waterproof protection layer.
Description
The utility model relates to the auxiliary hearing prosthesis of a kind of deaf-mute, especially relates to the transaudient interior derivative sensor that is used for audition of a kind of bone conduction through tooth.
In the background technology, the existing deaf-mute's of being used for hard of hearing formula ossiphone be a kind of be worn over hard of hearing after, rely on the mastoid after hard of hearing that sound wave is reached the inner ear auditory nerve through incus, malleus, semicircular canal, vestibular and through cochlea.Its shortcoming is: sound wave conducts tortuous in brain, and conducting effect is undesirable, when hearing aids has the loosening sound of just can't hear slightly.If want to reach hearing aid effect preferably, need hearing aids and hard of hearing tight the contact, as long-time use, hearing aids can be oppressed muscle, nerve and the blood vessel after hard of hearing, causes local pain, neural paralysis, thrombosis, muscle swelling.
The purpose of this utility model has been to overcome the weak point in the above-mentioned background technology, and a kind of interior derivative sensor is provided, and its conducting path is simple, and conducting effect is good, and is easy to use, and health is not had any harmful effect.
For achieving the above object, the technical solution that the utility model adopts is as follows:
Derivative sensor in a kind of, its special character is: comprise shell, be provided with audio frequency transformer in the shell, piezoelectric patches is connected with audio frequency transformer by lead, on the audio frequency transformer and be connected with the audio frequency input socket.
Can be connected with audio frequency amplifier on the above-mentioned audio frequency transformer, be connected with induction coil on the audio frequency amplifier and be connected with power supply.
Can be provided with fish tail and waterproof layer on the above-mentioned shell.
Can be connected with plug-type volume potentiometer on the above-mentioned audio frequency amplifier.
Above-mentioned power supply can be battery.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic diagram of audio emitting device;
Fig. 3 is the structural representation of external audio frequency line.
Number in the figure is described as follows:
The 1-electroplax, 2-electrode, 3-lead, 4-lead, 5-level connector lug, 6-level connector lug, the elementary connector lug of 7-, the elementary connector lug of 8-, 9-piezoelectric patches, 10-audio frequency transformer, 11-fish tail and waterproof layer.The 12-shell, 13-audio frequency amplifier, 14-output lead, the 15-output lead, 16-anode contact, 17-battery cathode contact, 18-anode lead, 19-battery cathode lead, 20-battery case, the 21-induction coil, 22-induction coil lead-in wire, 23-induction coil lead-in wire, the 24-end cap, the plug-type volume potentiometer of 25-, 26-audio jack, the 27-tone frequency channel wire, the 28-tone frequency channel wire, 29-audio frequency transmitting coil, 30-battery, 31-audio frequency input socket, the 32-tone frequency channel wire, 33-tone frequency channel wire, 34-audio jack, the 35-tone frequency channel wire, the 36-audio jack.
Below in conjunction with accompanying drawing the utility model is described in further detail: referring to accompanying drawing; comprise shell 12; shell 12 is provided with fish tail and waterproof layer 11; be provided with audio frequency transformer 10 in the shell 12; piezoelectric patches 9 comprises electrode 1 and electrode 2; be connected with secondary connector lug 6 with the secondary connector lug 5 of audio frequency transformer 10 with lead 4 by lead 3 respectively, audio frequency input socket 31 is connected on the output lead 14 and output lead 15 of audio frequency amplifier 13 by tone frequency channel wire 33 and tone frequency channel wire 31.Audio frequency amplifier 13 is connected on the elementary connector lug 7 and elementary connector lug 8 of audio frequency transformer 10 by output lead 14 and output lead 15.Audio frequency amplifier 13 is connected with induction coil 21 by induction coil lead-in wire 22 and induction coil lead-in wire 23, induction coil 21 is located on the battery case 20, battery case 20 1 ends are end cap 24, battery 30 is housed in the battery case 20, audio frequency amplifier 13 by the negative level of anode lead 18 and anode contact 16, battery cathode lead 19 an and battery contact 17 be connected with battery power and by plug-type volume potentiometer 25 as control switch and volume by-pass cock.During actual the use, the tone currents of external speakers reaches audio frequency transmitting coil 29 through audio jack 26, tone frequency channel wire 27 and tone frequency channel wire 28, to its around spatial emission frequency induction electromagnetic wave.And the frequency induction coil 21 that is in the interior derivative sensor in its emission space receives this frequency induction electromagnetic wave after frequency induction coil lead 21 and frequency induction coil 22 reach audio frequency amplifier 13; elementary connector lug 7 and elementary connector lug 8 that tone currents after the amplification reaches audio frequency transformer through the output lead 14 and the output lead 15 of audio frequency amplifier; passing to the electrode 1 of piezoelectric patches 9 and electrode 2 by the secondary connector lug 5 of audio frequency amplifier and secondary connector lug 6 through lead 3 and lead 4 again produces piezoelectric effects and is converted to sound wave; this sound wave through fish tail and waterproof layer 11 and transducer plastic compression shell 12 pass to bite shell on; lower teeth; reach cochlea and inner ear auditory nerve through tooth again; to acoustic vibration, hear sound so can feel (listening).The utility model also can directly receive outer audio signal, the audio jack 34 of tone frequency channel wire 35 is inserted in the audio frequency input socket 31 of interior derivative sensor, disconnect plug-type volume potentiometer 25, and with the external sound equipment output plughole of external audio frequency plug 36 insertions, can directly receive outer audio signal, this moment, audio frequency amplifier was not worked, and can save electrical source consumption.When with the magnetic induction way received signal, pull out audio jack 34 and open plug-type volume potentiometer 25, with the output plughole of audio jack 26 insertion external speakers, interior derivative sensor is with the magnetic induction way received audio signal.The utility model also can be used for detecting the break-make of telephone wire, during detection, pull out audio jack 26, the plug-type volume potentiometer 25 of derivative sensor in opening, audio frequency magnetic induction coil 21 is parallel near telephone wire, if can hear sound, illustrate that telephone wire is logical, if the noiseless telephone wire that then illustrates is in obstructed state.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
1, the utility model conducting effect is good, and is easy to use, eliminated existing ear-level hearing aid health is made The sense of discomfort that becomes;
