Abstract
The utility model is related to the sensors that piezoelectric patches field more particularly to a kind of waveform failing edge rule are decayed.By sensor body, the modeling frame in sensor body connects circular piezoelectric ceramic piece；The piezoelectric ceramic piece both ends are connect with lead, which flows out from modeling frame side, and are attached on modeling frame；Make the sensing vibrations rule that waveform failing edge rule decays.
Description
Technical field
The utility model is related to the sensors that piezoelectric patches field more particularly to a kind of waveform failing edge rule are decayed.
Background technology
Piezoelectric ceramic piece is a kind of electrophonic musical element, and piezoelectric ceramics medium material is put among two panels copper circular electrode
Material, when connecting AC audio signal on two plate electrodes, piezoelectric patches can occur vibration according to the big small frequency of signal and produce
Raw corresponding sound comes；There are following defects for current piezoelectric patches：1, piezoelectricity plate shape is hexagonal, is easy to cause piezoelectric patches
Vibrations are irregular, indirectly so that sensor vibration is irregular, 2, the lead at current piezoelectric patches both ends be both ends notch from modeling frame
Place's outflow, the end of a thread block the cavity at modeling frame both ends, to influence sensor free oscillation；3, current lead is from modeling frame both ends
It extracts, glue only seals lead both ends and stitch and piezoelectric patches junction, and extra lead portion is not sealing, is drawn
Free oscillation after line is powered, collision shell cause sensor integrally to shake very irregular；To sum up defect causes waveform sensor big
Mostly irregularly decay, the failing edge of waveform is disorderly and unsystematic.
Utility model content
The purpose of this utility model is to provide the sensor of the waveform failing edge rule decaying of vibrations rule.
The technical solution of the utility model is as follows：
The sensor of waveform failing edge rule decaying, which is characterized in that including sensor body, the modeling in sensor body
Frame 1 connects circular piezoelectric ceramic piece 2；The piezoelectric ceramic piece both ends are connect with lead 3, which flows from modeling frame side
Go out, and being attached to for rule is moulded on frame.Using circular piezoelectric patches so that piezoelectric patches vibrations rule, indirectly so that sensor vibration
Also regular；Since the lead at piezoelectric patches both ends is flowed out from modeling frame side, regularly it is attached on modeling frame, and lead is not close to modeling
At the platform of frame upper end, after such lead is drawn from side, the cavity of modeling frame will not be blocked.
The lead is located within the platform of modeling frame upper end.The lead portion on both sides is uniformly encapsulated with glue, is kept away
Exempt from collision modeling frame when lead vibrations.
Glue layer 4 is equipped on the outside of the lead.Glue layer is set with anchor leg.
The glue layer is located within the platform of modeling frame upper end.Glue avoids sensor from shaking without impinging on moulding at the platform of frame upper end
It is dynamic still irregular.
The utility model has the beneficial effects that：Using circular piezoelectric patches so that piezoelectric patches vibrations rule, indirectly so that passing
Sensor vibrations are also regular；Since the lead at piezoelectric patches both ends is flowed out from modeling frame side, regularly it is attached on modeling frame, and lead
At the platform of modeling frame upper end, after such lead is drawn from side, the cavity of modeling frame will not be blocked.
Description of the drawings
Through the following detailed description taken in conjunction with the accompanying drawings, the utility model objects, features and advantages above-mentioned and other will
It becomes apparent.
Wherein：FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model moment sensor waveform diagram；
Fig. 3 is the utility model waveform sensor schematic diagram；
In attached drawing, 1 is modeling frame, and 2 be piezoelectric ceramic piece, and 3 be lead, and 4 be glue layer.
Specific implementation mode
It is shown in Figure 1, the sensor of waveform failing edge rule decaying, which is characterized in that including sensor body, sensing
Modeling frame 1 on device ontology connects circular piezoelectric ceramic piece 2；The piezoelectric ceramic piece both ends are connect with lead 3, the lead from
The outflow of frame side is moulded, and being attached to for rule is moulded on frame.Using circular piezoelectric patches so that piezoelectric patches vibrations rule makes indirectly
Sensor vibration is also regular；Since the lead at piezoelectric patches both ends is flowed out from modeling frame side, regularly it is attached on modeling frame, and draw
Line after such lead is drawn from side, will not block the cavity of modeling frame not close to moulding at the platform of frame upper end.
The lead is located within the platform of modeling frame upper end.The lead portion on both sides is uniformly encapsulated with glue, is kept away
Exempt from collision modeling frame when lead vibrations.
Glue layer 4 is equipped on the outside of the lead.Glue layer is set with anchor leg.
The glue layer is located within the platform of modeling frame upper end.Glue avoids sensor from shaking without impinging on moulding at the platform of frame upper end
It is dynamic still irregular.
The above is only the preferred embodiment of the utility model, not does limit in any form to the utility model
It makes, to any simple modification, equivalent variations made by above example in every foundation the technical essence of the utility model, falls
Enter within the scope of protection of the utility model.
