Abstract
The invention discloses a novel ultrasonic transducer which comprises a seat body, a vibrating piece, piezoelectric ceramic, a vibration isolating and sound absorbing layer and a drying and moisture absorbing layer. The vibrating piece is arranged on the upper surface of the seat body. A first wire is led out of the seat body. The piezoelectric ceramic is arranged on the lower surface of the vibrating piece. The vibration isolating and sound absorbing layer is arranged on the lower surface of the piezoelectric ceramic. A second wire is led out of the piezoelectric ceramic. The drying and moisture absorbing layer wraps the periphery of the seat body and the lower surface of the vibration isolating and sound absorbing layer. By means of the manner, the novel ultrasonic transducer is simple in structure; due to the fact that the vibration isolating and sound absorbing layer is arranged, vibration is effectively controlled, and generation and spreading of noise are effectively reduced; the drying and moisture absorbing layer wraps the outer side, the moisture-proof and mildew-proof drying effect is achieved, and the phenomenon that moisture or water drops are attached to the surface of the transducer due to too high environment humidity, and consequently a series of problems of damage of the transducer and short circuits are caused is avoided; and performance is superior and novel, and certain economic benefits and market prospects are achieved.
Description
Technical field
The present invention relates to ultrasonic wave appliance field, particularly relate to a kind of Novel ultrasonic wave transducer.
Background technology
Ultrasonic transducer utilizes the piezo-electric effect of pottery the mechanical oscillation that ultrasonic wave produces changed into the signal of telecommunication or under electric field driven, produce mechanical oscillation thus send hyperacoustic device.Because its good transducing characteristic, be widely used in domestic meter detection field.Conventional ultrasonic transducer comprises housing, the piezoelectric ceramics be placed in housing, be close to the vibrating reed being used for being amplified by the ultrasonic wave received that piezoelectric ceramics installs.
At present, for prior art, ultrasonic transducer is when launching ultrasonic wave; due to the vibration of piezoelectric element, whole pedestal all can vibrate, and ultrasonic wave occurs; and; due to the vibration of piezoelectric element and pedestal, transducer operationally, can produce certain noise; in addition; ultrasonic transducer in use can adhere to moisture and the globule usually because ambient humidity is excessive, then can affect the use of transducer for a long time, also there is certain potential safety hazard simultaneously.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of Novel ultrasonic wave transducer, can play the desiccation of moistureproof and mildewproof and have vibration isolation de-noising performance.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of Novel ultrasonic wave transducer, it is characterized in that, comprising: pedestal, vibrating reed, piezoelectric ceramics, vibration isolation sound absorbing layer, dry moisture absorption layer; Described pedestal upper surface is provided with described vibrating reed, and described pedestal draws the first wire; The lower surface of described vibrating reed is provided with described piezoelectric ceramics; Described piezoelectric ceramics lower surface arranges described vibration isolation sound absorbing layer, and the second wire drawn by described piezoelectric ceramics; Described dry moisture absorption layer is coated on the lower surface by the periphery of described pedestal and described vibration isolation sound absorbing layer.
In a preferred embodiment of the present invention, described vibration isolation sound absorbing layer adopts rubber shock absorber.
In a preferred embodiment of the present invention, described dry moisture absorption layer adopts alumina solid gel, and thickness is 1-5mm.
The invention has the beneficial effects as follows: structure of the present invention is simple, arranging of vibration isolation sound absorbing layer effectively controls vibration, reduce generation and the propagation of noise, dry moisture absorption layer is coated on outside, play the desiccation of moistureproof and mildewproof, avoid because ambient humidity crosses ambassador's transducer face attachment moisture or the globule, and cause the generation of the damage of a series of transducer, short circuit problem, superior performance is novel, has certain economic benefit and market prospects.

Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of Novel ultrasonic wave transducer, is characterized in that, comprising: pedestal 1, vibrating reed 2, piezoelectric ceramics 3, vibration isolation sound absorbing layer 4, dry moisture absorption layer 5; Described pedestal 1 upper surface is provided with described vibrating reed 2, and described pedestal 1 draws the first wire 6; The lower surface of described vibrating reed 2 is provided with described piezoelectric ceramics 3; Described piezoelectric ceramics 3 lower surface arranges described vibration isolation sound absorbing layer 4, and the second wire 7 drawn by described piezoelectric ceramics 3; Described dry moisture absorption layer 5 is coated on the lower surface by the periphery of described pedestal 1 and described vibration isolation sound absorbing layer 4.
Be different from prior art.
In another embodiment, described vibration isolation sound absorbing layer 4 adopts rubber shock absorber, effectively can control vibrations, reduces the transmission of solid borne noise.
In another embodiment, described dry moisture absorption layer 5 adopts alumina solid gel, and thickness is 1-5mm, and drying property is superior, can avoid the damage of transducer in wet environment.
Structure of the present invention is simple, arranging of vibration isolation sound absorbing layer effectively controls vibration, reduce generation and the propagation of noise, dry moisture absorption layer is coated on outside, play the desiccation of moistureproof and mildewproof, avoid because ambient humidity crosses ambassador's transducer face attachment moisture or the globule, and cause the generation of the damage of a series of transducer, short circuit problem, superior performance is novel.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
