Description
Technical field
The present invention relates to the novel piezoelectric formula bone conduction auditory device of a kind of piezoelectric vibrator as the vibration sounding element, particularly, support the loudness that piezoelectric vibrator improves the piezoelectric type bone conduction auditory device by elastomer, and then solve the problem that piezoelectric type bone conduction auditory device loudness does not reach instructions for use.
Background technology
The piezoelectric type bone conduction auditory device has a good application prospect because have compact conformation, consumed power is low and is not subjected to advantage such as electromagnetic radiation.Start to walk early aspect the research of implanted piezoelectric bone conduction auditory device both at home and abroad at present, the research of wear-type piezoelectric bone conduction auditory device still is in the starting stage.Wear-type is easy to safeguard and change than the implanted piezoelectric bone conduction auditory device, but wear-type loudness does not reach instructions for use.Therefore, improve the loudness of wear-type piezoelectric bone conduction auditory device, just become the researcher urgent problem.
Summary of the invention
The invention provides a kind of resiliency supported formula circular piezoelectric oscillator bone conduction auditory device, by piezoelectric vibrator fixed support mode being changed into the method for resiliency supported mode, improve the loudness of piezoelectric type bone conduction auditory device, to solve the problem that piezoelectric type bone conduction auditory device loudness does not reach instructions for use.
The technical solution used in the present invention is: substrate and piezoelectric ceramic wafer are formed piezoelectric vibrator, piezoelectric vibrator is fixedlyed connected with support column, support column is fixedlyed connected with the round sheet spring, the upper surface of round sheet spring and rubber ring is fixedlyed connected, the lower surface of rubber ring is fixedlyed connected with base, loam cake is fixedlyed connected guided modes with base, audio signal wire links to each other with the both positive and negative polarity of piezoelectric vibrator.
The equal diameters of substrate and piezoelectric ceramic wafer among the present invention.
The round sheet spring mainly is made up of the brace summer that inner ring, outer ring, spiral distribute among the present invention, and the number of the brace summer that spiral distributes is symmetrically distributed spring more than or equal to three.
Advantage of the present invention is: by resiliency supported formula piezoelectric vibrator, solve existing piezoelectric type bone conduction auditory device loudness deficiency, and realize widening the piezoelectric bone conduction auditory dress to audio signal reproduce frequency range narrow etc. problem, from existing 1000-3000Hz, expand to 400-6000Hz, and improved the transaudient stability of piezoelectric bone conduction auditory dress vibration.
Description of drawings
Fig. 1 is an overall structure cutaway view of the present invention.
Fig. 2 is round sheet spring structure figure.
Embodiment
The equal diameters of substrate 3 and piezoelectric ceramic wafer 4.
The round sheet spring mainly is made up of the brace summer that inner ring, outer ring, spiral distribute, and inner ring is connected with support column; It is to guarantee that spring longitudinal deformation amount and load are linear change that the spiral brace summer mainly acts on, and guarantees the stability of vibration of hearing device, so the brace summer number guarantees that more than or equal to three the spring symmetrical distribution gets final product.
The effect of round sheet spring 6 is to support piezoelectric vibrator; And make hearing device have two rank natural frequencys, thereby improve the loudness of piezoelectric bone conduction auditory device, widen the piezoelectric bone conduction auditory dress to audio signal reproduce frequency range narrow etc. problem, and improved the transaudient stability of piezoelectric bone conduction auditory dress vibration; Support column 5 is as the connection element of circular piezoelectric oscillator and round sheet spring 6, main effect is to support the circular piezoelectric oscillator and the circular piezoelectric oscillator is accurately located, and guarantee between circular piezoelectric oscillator and the round sheet spring 6 the certain deformation scope is arranged, allow both not produce mutual interference; Conductive membranes 2 not only can make the upper surface of circular piezoelectric oscillator fully contact with people's frontal bone, increases the transmission area and reduces energy loss, can also improve the stability of hearing device output sound signal; The effect of the base 7 of piezoelectric type bone conduction auditory device is to eliminate acoustic short circuit and the effect that reduces to leak sound and the round sheet spring is played support; The main effect of loam cake 1 be with conductive membranes 2 on firm banking 7; Audio signal wire 9 links to each other with the both positive and negative polarity of piezoelectric vibrator; The main effect of rubber ring 8 is structural dampings of regulating resiliency supported formula circular piezoelectric oscillator bone conduction auditory device, and then reduces the influence of covibration to resiliency supported formula circular piezoelectric oscillator bone conduction auditory device vibration sounding stability.Make hearing device that two tangible natural frequencys be arranged by the resiliency supported mode, thus the very high loudness of resiliency supported formula circular piezoelectric oscillator bone conduction auditory device at full frequency band.
