Abstract
The utility model provides a vibration transducer, which is characterized in that the vibration transducer comprises a piezoelectric material sheet; a copper substrate and a silver plating layer are respectively laid at both sides of the piezoelectric material sheet; the copper substrate adopts a positive pole and is led out through a leading wire; the silver plating layer adopts a negative pole and is led out through a leading wire as well; the copper substrate, and the piezoelectric material sheet and the outer layer of the silver plating layer are wrapped with silica gel. The transduction efficiency can be improved through the structural design, the frequency response scope can be expanded, the vibration can be effectively transmitted out, and simultaneously the transducer is provided with the performance of water resistance and impact resistance to a certain extent.
Description
Technical field
The utility model relates to a kind of vibration transducer, is used for converting the electric energy of audio signal to vibrational energy.
Background technology
The method that audio signal voltage can be converted effectively to vibration has multiple, as magnetoelectricity moving-coil type, magnetoelectricity reed or the like.They are lower with the conversion efficiency that " electric energy " converts " vibrational energy " to, and frequency response range is narrow.
Summary of the invention
Main purpose of the present utility model is to solve above-mentioned these problems, provide a kind of piezoelectric type vibration transducer, to improve transducer conversion efficiency, broadening frequency response range, and can effectively this conduct vibrations be come out, can make this transducer waterproof, shock resistance to a certain extent simultaneously again.
The purpose of this utility model is achieved by following technical proposals:
A kind of vibration transducer is characterized in that: comprise a patch of piezoelectric material; These patch of piezoelectric material both sides are covered with copper base and silver coating respectively; Described copper base is anodal, by lead draw, described silver coating is negative pole, draw by lead; Described copper base, patch of piezoelectric material, silver coating are wrapped up by silica gel sealing.
The beneficial effects of the utility model are not consumed power, also friction generation simultaneously under wait state; When audio driven voltage arrives, at first make patch of piezoelectric material produce piezoelectric effect, produce corresponding vibration, and have fabulous elasticity and a flexible silica gel material by what be wrapped in along with the audio driven voltage that applies, the one side sound-absorbing, on the one hand outside conduction vibration.Simultaneously, possess waterproof and impact resistance well again.
Description of drawings
Fig. 1 is the vibration transducer structure chart.
Embodiment
Below by drawings and Examples the utility model is further described.
As shown in Figure 1, be provided with patch of piezoelectric material 1 in the vibration transducer of the present utility model, the thin slice of this patch of piezoelectric material 1 for making by piezoelectric, it can convert audio signal voltage to vibration effectively, is the core component of the utility model vibration transducer.Be covered with copper base 2 and silver coating 3 respectively in the both sides of this piezoelectric 1, wherein copper base 2 is drawn by lead 5 as the positive pole of transducer, and silver coating 3 is drawn by lead 6 as the negative pole of transducer.Copper base 2, patch of piezoelectric material 1, silver coating 3 outer employings have fabulous elasticity and flexible silica gel material 4 sealed envelope, one side sound-absorbing, on the one hand outside conduction vibration.Simultaneously, possess waterproof and impact resistance well again.
