The utility model provides a lath flexible transducer can solve the problem that frequency of operation hardly reaches ultralow frequency channel, has the mechanical resonant frequency of ultralow frequency, near the resonance point, can improve the electroacoustic efficiency by a wide margin.
Description
Technical field
This utility model relates to transducer, especially a kind of bend transducer.
Background technology
Existing intrasonic transducer is mainly moving-coil type transmitting transducer, and its shortcoming is: electroacoustic efficiency is very low, is only capable of reaching 0.1%；And existing piezoelectric ceramics transmitting transducer, owing to vibrated mode restricts, under limited metric space, its operating frequency is extremely difficult to ultralow frequency range (30 ~ 100Hz).
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of bend transducer, it is possible to solves operating frequency and is extremely difficult to the problem of ultralow frequency range, has ultra-low frequency mechanical resonant frequency, near resonance point, electroacoustic efficiency can be greatly improved.
For solving above-mentioned technical problem, this utility model be the technical scheme is that a kind of bend transducer, including sound transmitting rubber housing, sound transmitting rubber housing top and bottom are respectively arranged with upper end cover and bottom end cover, sound transmitting rubber housing, airtight oil sac is formed between upper end cover and bottom end cover, it is filled with oil reservoir in airtight oil sac, bottom end cover top is provided with fixing seat, multiple lath oscillators are fixedly installed on fixing seat and arrange at a certain distance and form definite shape, fixing seat between multiple lath oscillators is provided with earth pressure release backing, cable is fixedly mounted on upper end cover by ring flange, each lath oscillator electrically connects with cable respectively；
In lath oscillator, metallic implants both sides are respectively bonded with the first piezoelectric ceramic wafer and the second piezoelectric ceramic wafer, constitute vibration main body, described vibration main body being fixedly mounted on the fixing seat of support plate by trip bolt, the first piezoelectric ceramic wafer and the second piezoelectric ceramic wafer are in parallel on circuit form again.
Multiple lath oscillators are bolted and are installed on fixing seat.
Multiple lath oscillators also arrange that formation is circular or square at a certain distance.
The bend transducer that this utility model provides, connected on mechanical type by the first piezoelectric ceramic wafer on lath oscillator and the second piezoelectric ceramic wafer, pattern in parallel on circuit form, under electric field excitation, its direction of vibration is contrary, during a piece of extension, another sheet shrinks, during a piece of contraction, another sheet is upheld, and so comes and goes alternately, provides the driving force of a bending vibration for metallic implants.So, under the effect of alternating electric field, lath oscillator produces ultra-low frequency bending vibration.The while of several lath oscillators, vibrate the vibration that can drive surrounding medium in the same direction, it is possible to solve operating frequency and be extremely difficult to the problem of ultralow frequency range, there is ultra-low frequency mechanical resonant frequency, near resonance point, electroacoustic efficiency can be greatly improved.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the schematic diagram of this utility model lath oscillator.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of bend transducer, it is characterized in that: include sound transmitting rubber housing 6, sound transmitting rubber housing 6 top and bottom are respectively arranged with upper end cover 3 and bottom end cover 8, sound transmitting rubber housing 6, airtight oil sac is formed between upper end cover 3 and bottom end cover 8, oil reservoir 4 it is filled with in airtight oil sac, bottom end cover 8 top is provided with fixing seat 9, multiple lath oscillators 5 are fixedly installed on fixing seat 9 and arrange at a certain distance and form definite shape, fixing seat 9 between multiple lath oscillators 5 is provided with earth pressure release backing 7, cable 1 is fixedly mounted on upper end cover 3 by ring flange 2, each lath oscillator 5 electrically connects with cable respectively；
In lath oscillator 5, metallic implants 10 both sides are respectively bonded with the first piezoelectric ceramic wafer 11 and the second piezoelectric ceramic wafer 12, constitute vibration main body, described vibration main body being fixedly mounted on the fixing seat 13 of support plate by trip bolt, the first piezoelectric ceramic wafer 11 and the second piezoelectric ceramic wafer 12 are in parallel on circuit form again.
Multiple lath oscillators 5 are bolted and are installed on fixing seat 9.
Multiple lath oscillators 5 also arrange that formation is circular or square at a certain distance.
On lath oscillator 5, the first piezoelectric ceramic wafer 11 and the second piezoelectric ceramic wafer 12 are connected on mechanical type, pattern in parallel on circuit form, under electric field excitation, its direction of vibration is contrary, during a piece of extension, another sheet shrinks, during a piece of contraction, another sheet is upheld, so come and go alternately, provide the driving force of a bending vibration for metallic implants 10.So, under the effect of alternating electric field, lath oscillator 5 produces ultra-low frequency bending vibration.The while of several lath oscillators 5, vibrate the vibration that can drive surrounding medium in the same direction, it is possible to solve operating frequency and be extremely difficult to the problem of ultralow frequency range, there is ultra-low frequency mechanical resonant frequency, near resonance point, electroacoustic efficiency can be greatly improved.
