Description
Technical field
The present invention relates to vibration-testing fields, and in particular to a kind of horn vibration detection device.
Background technique
Currently, just following horn vibration detection device is developed using semiconductor integrated circuit manufacturing technology, it should
Horn vibration detection device on a silicon substrate lamination monocrystalline silicon or polysilicon and form film, and by the film be used as diaphragm.
The metal phases ratio such as diaphragm made of silicon and aluminium or titanium, internal stress is few and density is low, therefore can obtain the loudspeaker of high sensitivity
Vibration detection device, and it is good with the matching of semiconductor integrated circuit manufacturing process.The condenser type wheat of the prior art
In gram wind, after the surface for the semiconductor substrate being made of monocrystalline silicon face is formed with diaphragm (movable electrode) and fixed electrode,
Etching mask is formed in the back side peripheral part of the semiconductor substrate, semiconductor substrate is etched from back side to surface, is partly being led
The central portion of structure base board offers through hole.As a result, diaphragm will be fixed on the surface of semiconductor substrate, central portion around it
It is supported on through hole, can be vibrated by acoustical vibration etc. hollowly.
But in the Electret Condencer Microphone of this structure, in addition, not due to conventional electromagnetic sensor measurement accuracy
Height, volume is bigger, will cause inconvenience when in use.
Summary of the invention
The technical scheme adopted by the invention is that: a kind of horn vibration detection device, the horn vibration detection device packet
It includes:
Shell sets controller on the shell, is located at the iron core of interior of shell and the coil being wrapped on iron core and is located at
Magnet on shell.
The coiling combination of the iron core and coil composition is entrenched on the inner wall of shell；
The magnet be it is rodlike, the top and bottom of shell are fixed on by upper elastic body and lower elastic body；
The controller, comprising: test circuit module and display module.
Further, the magnet is rodlike, and rodlike magnet is cylinder, and mid diameter is small, and both ends diameter is big.
Further, the upper elastic body and lower elastic body are resonant springs, can pass through extraneous vibration band moving magnet
It moves up and down.
Further, the coiling group is combined into hollow cylindric, is made of multiple coils.
Further, the coil is connect with the test circuit module of controller respectively.
Further, the shell is the circular metal shell of sealing.
Further, the display module is LCD MODULE.
The beneficial effects of the present invention are: application scheme passes through and the permanent magnet fixed among coil with spring is arranged in,
It drives permanent magnet with respect to the relative displacement of coil by the vibration of spring, so that magnetic field is changed, and then make to produce in coil
Motional electromotive force, then shown the specific value of test by display module by test circuit module, make vibration setting more
Be it is accurate and intuitive readable, can also be achieved the miniaturization of horn vibration detection device, can be used for by horn vibration detection device
Increase sound equipment acoustic compliance when in acoustic sensor, improves the sound quality of loudspeaker.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of horn vibration detection device according to an embodiment of the invention.
Specific embodiment
Invention is further described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, the technical scheme adopted by the invention is that: a kind of horn vibration detection device, the horn vibration
Detection device includes:
It shell 10, the controller 20 being located on shell 10, the iron core 11 being located inside shell 10 and is wrapped on iron core 11
Coil 12 and the magnet 30 that is located on shell 10.
The coiling combination that the iron core 11 and coil 12 form is entrenched on the inner wall of shell 10；
The magnet 30 be it is rodlike, the top and bottom of shell 10 are fixed on by upper elastic body 31 and lower elastic body 32；
The controller 20, comprising: test circuit module and display module.
In test, according to the law of electromagnetic induction, the magnetic circuit system in Constant Direct Current magnetic field is generated in coil 12, when w circle line
Circle in stationary magnetic field when moving, if the magnetic flux for passing through coil is Φ, then the induced potential E in coil and flux change rate d Φ/
Dt has following relationship:
E=-w (d Φ/dt) interlinks with the magnetic flux in magnetic field and generates induced electromotive force, and bullet is used among coil by setting
The fixed permanent magnet of spring drives permanent magnet with respect to the relative displacement of coil, magnetic field is made to change by the vibration of spring,
And then make to generate electromotive force in coil, then show the specific value of test by display module by test circuit module
Come, keeps vibration setting more accurate and intuitive readable, can also be achieved the miniaturization of horn vibration detection device.
Further, the magnet 30 is rodlike, and rodlike magnet 30 is cylinder, and mid diameter is small, and both ends diameter is big,
Setting improves the precision incuded in this way.
Further, the upper elastic body 31 and lower elastic body 32 are resonant springs, can be driven by extraneous vibration
Magnet moves up and down, and keeps its induction vibration more sensitive.
Further, the coiling group is combined into hollow cylindric, is made of multiple coils, convenient for manufacture installation.
Further, the coil 12 is connect with the test circuit module 21 of controller 20 respectively, by what is generated in coil
The value of electromotive force passes to controller 20, carries out conversion operation.
Further, the shell 10 is the circular metal shell of sealing.
Further, the display module is LCD MODULE.
Horn vibration detection device of the present invention is led to by the way that the permanent magnet fixed among coil with spring is arranged in
It crosses the vibration of spring and then permanent magnet is driven so that magnetic field is changed with respect to the relative displacement of coil, and then make to generate in coil
Electromotive force, then shown the specific value of test by display module by test circuit module, make vibration setting more
It is accurate and intuitive readable, it can also be achieved the miniaturization of horn vibration detection device, horn vibration detection device can be used for sound
Increase sound equipment acoustic compliance when ringing in sensor, improves the sound quality of loudspeaker.
