HydrophoneOne, technical field：
The present invention relates to a kind of pull the plug also can clearly hear the device of sound, and in particular to a kind of underwater auditionDevice.
Two, background technology：
In background technology, the device due to that can hear sound is not waterproof, can not work in water, and waterproof device existsSound is can't hear again in water, so in the prior art, naked body can be made one is immersed in the water ear water inlet also to hear in waterThe device of sound does not have so far, once has the diving telephone in heavy weight diving takes the helmet in the past, but in the diving dress helmetBut only have compressed air there is no water, and make to dive because the device tows the diving telephone line installed side by side with compressed gas input pipeThe underwater movement critical constraints system of water personnel, so in recent years by the using flexible without appendix and diving telephone linePressure type tank of compressed air diving suit of bearing gradually replace.
Three, invention content：
The present invention provides a kind of hydrophone, can make one naked to solve the shortcoming in above-mentioned background technologyBody is immersed in the water, and two ears can also be passed into water by the bone that the transaudient effect of osteoacusis of tooth makes the people to pull the plug pass through toothIt leads and hears sound.
To achieve the above object, the technical solution adopted by the present invention is：A kind of hydrophone, it is characterised in that：IncludingShell, piezoelectric patches two, waterproof grommet one, waterproof grommet two, inductor, waterproof sealing pipe, conducting wire one, is led at piezoelectric patches oneLine two, waterproof audio plug, water-proof protection cover, titanium dioxide silicone grease and titanium dioxide silicone grease coating, the both sides in the shell are insertedEquipped with piezoelectric patches one and piezoelectric patches two, the piezoelectric patches one and piezoelectric patches two are provided with waterproof grommet on the contact surface of shellOne and waterproof grommet two, one end of conducting wire one and conducting wire two is connect with inductor, and the other end connects the defeated of waterproof audio plugEnter end, the piezoelectricity pole of piezoelectric patches one and piezoelectric patches two connect with conducting wire two respectively, piezoelectric patches one, piezoelectric patches two copper sheet pole distinguishIt is connect with conducting wire one, the input terminal of waterproof audio plug is toroidal, and silica has been filled on the inside of toroidalFat, outside are provided with water-proof protection cover.
The waterproofing protection cover outer surface is coated with titanium dioxide silicone grease coating.
Waterproof sealing pipe is provided between the conducting wire two and shell.
The material of the water-proof protection cover is rubber.
Compared with prior art, the present invention has the advantage that as follows with effect：The present invention can make one/seabed of diving beneath the water,People's nude immerses two ears in water and enters water also and can hear the hydrophone of sound, it is flexible and convenient to use, quality-high and inexpensive, waterPleasant to the ear sound effect is good, and stealth is hidden when use, and listening is kept absolutely secret, to human body without any harmful effect.
Four, it illustrates：
Fig. 1 is the structural diagram of the present invention.

Five, specific implementation mode：
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments：
Referring to Fig. 1：Hydrophone, including shell 1, piezoelectric patches 1, piezoelectric patches 23, waterproof grommet 1, anti-watertightSeal 28, inductor 6, waterproof sealing pipe 9, conducting wire 1, conducting wire 25, waterproof audio plug 10, water-proof protection cover 11, dioxySiClx fat 12 and titanium dioxide silicone grease coating 13, the both sides in the shell 1 are inserted with piezoelectric patches 1 and piezoelectric patches 23, describedPiezoelectric patches 1 and piezoelectric patches 23 are provided with waterproof grommet 1 and waterproof grommet 28, conducting wire on the contact surface of shell 11 and one end of conducting wire 25 connect with inductor 6, the other end connects the input terminal of waterproof audio plug 10, one 2 He of piezoelectric patchesThe piezoelectricity pole of piezoelectric patches 23 is connect with conducting wire 25 respectively, piezoelectric patches 1, piezoelectric patches 23 copper sheet pole respectively with conducting wire 1 connectIt connects, the input terminal of waterproof audio plug 10 is toroidal, and titanium dioxide silicone grease 12, outside have been filled on the inside of toroidalIt is provided with water-proof protection cover 11,11 outer surface of water-proof protection cover is coated with titanium dioxide silicone grease coating 13, the conducting wireWaterproof sealing pipe 9 is provided between 25 and shell 1, the material of the water-proof protection cover 11 is rubber.
The present invention is when waterproof audio plug 10 enters socket, the horn mouth rubber water-proof protection in 10 outside of waterproof audio plugAfter cover 11 is squeezed, it will be adsorbed on audio output socket, meanwhile, filling is full in rubber water-proof protection cover horn mouth twoOxidation silicone grease 12 is squeezed by rubber water-proof protection cover 11 and overflows and seal the engaging portion of waterproof audio plug 10 and socket, toAchieve the purpose that waterproof sealing after being inserted into.
Extraneous audio signals inside waterproof audio plug 10 by reaching the inductor in parallel with conducting wire 25 by conducting wire 256, the another end of inductor 6, the copper sheet pole of piezoelectric patches 1 and piezoelectric patches 23 are flowed through in the piezoelectricity pole of piezoelectric patches 1 and piezoelectric patches 23The Yin Pin Xin rotation road that is formed to conducting wire 1 makes audio signal generate piezoelectric effect on piezoelectric patches 1 and piezoelectric patches 23 to shakeIt is dynamic, it restores voice signal, reach inner ear using the osteoacusis for biting the tooth on 23 copper sheet of piezoelectric patches 1 and piezoelectric patchesNeural ciliated cell makes hearer be immersed in make extraneous audio signals reach through listening under water the interior auricularis of hearer through toothIn water sound is heard with tooth by hydrophone.
