Abstract
The present utility model provides a piezoelectric ceramic bone conduction hearing-aid earphone. Two groups of piezoelectric ceramic sheets with opposite polarity are attached to an elastic metal sheet, a conducting wire is used for leading out positive and negative poles of the piezoelectric ceramic sheets to from oscillators, the oscillators are packaged with sound-absorbing soft plastic , the packaged oscillators are fixed in a bearing pedestal and arranged in a front cover and a rear shell, and then a silica gel earplug is arranged. The piezoelectric ceramic bone conduction hearing-aid earphone is light in weight, comfortable to wear and free of electromagnetic radiation. hearing impaired people can hear sound through skull, clear conversation can be realized in strong noise environment, the purpose of resisting strong noises can be realized; and the waterproof function can be realized.
Description
Technical field
The utility model belongs to the hearing aid earphone technical field, is specifically related to a kind of piezoelectric ceramic bone conduction hearing aid earphone.
Background technology
The piezoelectric ceramic bone conduction hearing aid earphone is by piezoelectric ceramic osteoacusis oscillator, carries out sound transmission with the osteoacusis mode, realizes the device of bone conduction earphone function.
Bone conduction hearing aid earphone is by skull, directly imports sound into cochlea and auditory nerve, makes the dysaudia personage can hear sound.Traditional bone conduction hearing aid earphone generally is with electromagnetic type transducing mode, complex structure, and weight is heavier, has simultaneously electromagnetic radiation, can produce electromagnetic interference, also can be subjected to electromagnetic field effects.
Summary of the invention
The purpose of this utility model provides a kind of piezoelectric ceramic bone conduction hearing aid earphone, has lightweight, comfortable wearing, the advantage of electromagnetic-radiation-free.
The technical solution of the utility model is: a kind of piezoelectric ceramic bone conduction hearing aid earphone, it is characterized in that two groups of opposite polarity piezoelectric ceramic pieces are attached to forms oscillator on the elastic sheet metal, with wire the piezoelectric ceramic piece both positive and negative polarity is drawn, the encapsulation of oscillator external application sound-absorbing soft plastic, oscillator after the encapsulation is fixed in the supporting base, pack in protecgulum and the back cover, load onto at last silica gel earplugs.
The utility model utilizes piezoelectric ceramic osteoacusis oscillator, and audio electrical signal is directly changed into mechanical oscillation signal, realizes the bone conduction hearing aid earphone function.And the employing cantilever beam structure, obtain lower F0 and higher sensitivity, have lightweight, comfortable wearing, the advantage of electromagnetic-radiation-free.Can make person hard of hearing hear sound by skull; Also can under high-noise environment, realize clearly conversation, reach high antimierophonic purpose; Has simultaneously water-proof function.
Description of drawings
Fig. 1 is outline drawing of the present utility model.
Fig. 2 is structure cutaway view of the present utility model.
Embodiment
As depicted in figs. 1 and 2: two groups of opposite polarity piezoelectric ceramic pieces 1,2 are attached on the elastic sheet metal 3 and form oscillator, with wire 9 the piezoelectric ceramic piece both positive and negative polarity is drawn, with sound-absorbing soft plastic 7 oscillator is encapsulated again, be fixed in the supporting base 6, pack in protecgulum 4 and the back cover 5, load onto at last silica gel earplugs 8.
When feeding two groups of piezoelectric ceramic pieces 1 and 2 audible communication signal, can drive elastic sheet metal 3 and produce together audio frequency vibration thereupon, this vibration can promote airborne gas molecule and produce vibration, the vibration of gas molecule in the air, import the eardrum in people's ear into, just can allow the people hear sound.Sound-absorbing soft plastic 7 is a kind of soft plastics with sound absorption, with after the oscillator encapsulation, just makes the audio electrical signal energy with it, and major part converts mechanical vibrational energy to, and not radiation in the air makes sound not import people's ear into by air.And when the osteoacusis oscillator was touched people's skull, the audio frequency vibration signal namely was directly delivered to cochlea and the auditory nerve of people's ear by skull, allowed the people hear the voice signal of its transmission.Can help person hard of hearing again to hear sound, also can realize under the high-noise environment clearly voice call function.Because of the packed material parcel of electrode, this product has also had good water resistance simultaneously.
