Natural heat dissipation.
However, with the development of electronic technology, the use intensity of equipment is also increasing, lead to the heat producing also more next
More, under many circumstances, this natural heat dissipation is no longer able to meet the radiating requirements of equipment.For example, for rru,
Traditional rru can meet radiating requirements by its toothed surfaces, but is as the rise of 3g, 4g or even 5g network, r
The radiating requirements more and more higher of ru is it is necessary to help its radiating by extraneous wind-force.
At present, generally adopt fan to be that the said equipment provides extraneous wind-force, for example by fan from the top of rru or
Side provides wind-force.Fan generally comprises the rotatable parts such as flabellum and bearing, and the rotatable parts such as bearing are deposited unavoidably when using
The problems such as power consumption height, noise are big.
Additionally, this radiating mode also has several disadvantages in that
1st, due to the restriction of electric fan and rotatable parts size, the space that fan takies is very greatly it is impossible to be applied to extra
The less situation in space.If fan is made same product with the equipment (such as rru) with radiation tooth, this product
Size also cannot do frivolous.
2nd, because the quantity generally ratio of fan is relatively limited, therefore losing efficacy one, it is very big that radiating effect is affected.
3rd, because the service life of the rotatable parts such as bearing is generally shorter it is therefore desirable to higher maintenance cost.
4th, easy dust stratification.
And in embodiments of the present invention, provide a kind of radiating module and system, control method and relevant device, with realize to
While there is the equipment of radiation tooth extraneous wind-force is provided, reduce power consumption and reduce noise.

Individual vibration unit, that is, vibration unit 1011, vibration unit 1012, vibration unit 1013, vibration unit 1014 ..., vibration single
First 101m, wherein, m >=2.It should be noted that in FIG, it is in yi word pattern for exemplifying with the arrangement of each vibration unit,
In fact, each vibration unit can also be not construed as limiting to this for other arrangement modes, the embodiment of the present invention.
The radiating module of the present embodiment is used for the equipment with radiation tooth that is to say, that the radiating module of the present embodiment is real
It is to provide extraneous wind-force to the equipment with radiation tooth on border, thus realizing radiating.
Wherein, each vibration unit of the present embodiment includes piezoelectric element and solid piece, piezoelectricity unit in each vibration unit

Element 201 is connected with one end of solid piece 202.After piezoelectric element 201 is energized, flex effect can be produced, thus produce shaking
Dynamic, because piezoelectric element 201 is connected with one end of solid piece 202, therefore now piezoelectric element 201 can drive solid piece 202
Swing, thus producing wind-force.Specifically, when piezoelectric element 201 passes to alternating current, piezoelectric element 201 can drive solid piece
202 is of reciprocating vibration along the direction of arrow a, and therefore air-out wind direction is to connect one end of piezoelectric patches 201 to solid from solid piece 202
Piece 202 is not connected with one end of piezoelectric patches 201, that is, forward air-out (direction usually shown in arrow b differ 60 ° within side
To), air intake direction can be for any one of the left and right of thermal modules, upper and lower both sides and rear portion or multiple directions.
In the present embodiment, fixing device 102 is connected with the piezoelectric element in each vibration unit, is used for fixing described dissipating
Thermal modules.For example shown in Fig. 1, fixing device 102 includes multiple sub-devices, and each sub-device is used for fixing a vibration unit.
Or, fixing device 102 can also be a device, fixing all of vibration unit, thus fixing radiating module.The present invention is real
Apply example this is not limited.
By technique scheme, the radiating module in the present embodiment includes at least two vibration units 101, respectively
Individual vibration unit includes piezoelectric element and solid piece, and in a vibration unit, piezoelectric element is connected with one end of solid piece, because
This can drive solid piece to swing when piezoelectric element, thus producing wind-force, and the wind-force producing is used for having radiating
The equipment of tooth provides extraneous wind-force, realizes radiating effect.And in the embodiment of the present invention, no longer adopt the rotatable parts such as bearing, because
This not only reduces power consumption, and reduces noise.And, the radiating module in the present embodiment also has dedusting, replaces vibration
The functions such as disturbance piece.
Additionally, the scheme of the present embodiment also has the advantage that
1st, employ the air-out mode being driven solid piece by piezoelectric element in the present embodiment, therefore without using flabellum and axle
Piezoelectric element in rotatable parts, and the present embodiment and the solid piece such as hold compared to the rotatable parts such as flabellum and bearing, size
Less, and fixing device also only need to realize fixing radiating module, size does not have considerable restraint yet, therefore, the radiating of the present embodiment
The space that module takies is less, goes for the less situation of exceptional space.If by the radiating module of the present embodiment and tool
The equipment (such as rru) having radiation tooth makes identical product, and it is very frivolous that the size of this product can be done, and, radiates
Module not only can be arranged at the top of equipment (such as rru) with radiation tooth and side moreover it is possible to be arranged at radiating
The centre of the equipment (such as rru) of tooth.
2nd, employ the mode of the combination air-out of multiple vibration units in the present embodiment, the unit that therefore lost efficacy is to radiating
Influential effect very little.
3rd, no longer adopt the rotatable parts such as bearing in the present embodiment, and the life-span of piezoelectric element and solid piece be all long,
The radiating module life-span of therefore the present embodiment is longer, and maintenance cost is lower.
4th, employ multiple vibration units mode realizing air-out of reciprocating vibration in the present embodiment, be therefore difficult dust stratification.
Solid piece in the present embodiment can be done for sheet metal, plastic sheet, wood chip, hard paper or various synthetic material
The chip solid becoming.And piezoelectric element is the device made using the piezoelectric effect of material, can be lamellar, the shape such as bar-shaped.
A vibration unit in the present embodiment, piezoelectric element is connected with one end of solid piece, at this point it is possible to be as figure
Shown in 2, solid piece is longer than piezoelectric element, and whole piezoelectric element is connected to one end of solid piece.Or Fig. 2 institute can also be not so good as
Show, solid piece is not limited with the size of piezoelectric element, a part for piezoelectric element is connected to one end of solid piece.In this enforcement
In example, the reciprocally swinging of the one end not mainly being connected with piezoelectric element by solid piece provides wind-force.
In the present embodiment, the distance between each vibration unit can be set and be more than predetermined threshold value, and predetermined threshold value root
Amplitude according to the swing of solid piece determines.
The fixing device 102 of the present embodiment is connected with the piezoelectric element in each vibration unit, is used for fixing radiating module.
Wherein, fixing device 102 can be connected with the one end not being connected with solid piece on piezoelectric element, thus reducing to piezoelectric element
Vibration impact.
Can be that setting of radiation tooth is had by what radiating module was fixed on the present embodiment by fixing device 102 in the present embodiment
Standby outside is it is also possible to be integrally fixed on this equipment.Illustrate with reference to figure.For convenience of explanation, with the present embodiment
As a example having the equipment specially rru of radiation tooth, the equipment with radiation tooth of certain the present embodiment can also be except rr
Other equipment beyond u, the embodiment of the present invention does not limit to this.
Fixing device 102 can be that the radiating module 301 of the present embodiment is fixed on the outside of rru302, such as Fig. 3
Shown, radiating module 301 is fixed on the direction of radiation tooth 3021 facing rru302, and air-out direction faces
Radiation tooth 3021.
Fixing device 102 can be to be fixed on rru302 by the radiating module 301 of the present embodiment, such as Fig. 4 institute
Show, radiating module 301 is fixed on the top of rru302, can be now air-out direction be from the top of rru302 to r
The bottom air-out of ru302.As shown in figure 5, radiating module 301 can also be the bottom being fixed on rru302, now permissible
Be air-out direction be from rru302 top air-out from bottom to rru302.As shown in fig. 6, radiating module 301 also may be used
To be integrally fixed at the centre of rru302, air-out direction can be arranged according to the actual requirements.
When radiating module 301 is fixed on rru302 fixing device 102, fixing device 102 can be dissipated
The radiation tooth that thermal modules 301 are fixed on the radiation tooth 3031 of rru302 or remove a part, by radiating module
301 are fixed on rru302, and radiating module instead of the part radiation tooth of rru302.
In the embodiment of the present invention, mainly swung by the drive stator of reciprocating vibration of piezoelectric element, thus producing wind-force, real
Existing radiating effect.In fact, the swaying direction of each stator can produce certain impact to air-out effect, pass through separately below
Two embodiments are illustrated.
First pass through an embodiment and the swaying direction of each stator whole identical situation is described.
As shown in fig. 7, embodiments providing the second embodiment of radiating module, for having setting of radiation tooth
Standby, the radiating module of the present embodiment includes at least two vibration units 701 and fixing device 702.For example, at least two in Fig. 7
Individual vibration unit 701 specifically includes m vibration unit, that is, vibration unit 7011, vibration unit 7012, vibration unit 7013, shake

Wherein, each vibration unit of the present embodiment includes piezoelectric element and solid piece, piezoelectricity unit in each vibration unit
Part is connected with one end of the solid piece in this vibration unit.Fixing device 702 is connected with the piezoelectric element in each vibration unit,
For fixing described radiating module.
Each piezoelectric element of the present embodiment all passes to alternating current, and described alternating current makes each described piezoelectric element same
One moment was vibrated to same direction.
After piezoelectric element is energized, piezoelectric element produces vibration, therefore, it is possible to drive solid piece to swing, thus producing wind
Power.Wherein, the direction of vibration of piezoelectric element and the positive negative correlation being energized, therefore, after passing to alternating current to piezoelectric element, can
Piezoelectric element is produced of reciprocating vibration.
Therefore, in the present embodiment, each piezoelectric element is of reciprocating vibration in the presence of alternating current, wherein, each piezoelectricity
Element vibrates to same direction in synchronization, and therefore each solid piece also swings to same direction in synchronization.Such as Fig. 7
Shown, at a time, each piezoelectric element all vibrates to the right, and therefore each solid piece all swings to the right, therefore to the right
Upper direction air-out direction.In subsequent time, each piezoelectric element can all vibrate to the left, and therefore each solid piece is whole to the left
Swing.
In the present embodiment, alternating current can be periodic signal, and now, each piezoelectric element is periodically of reciprocating vibration.
In the present embodiment, can be by adjusting the frequency of alternating current or amplitude, or solid piece or piezoelectric element
Size, realizes the regulation of wind-force size.For example, if increasing ac frequency, the frequency of solid piece swing can therefore be increased, thus
Increase wind-force.
By technique scheme, provide a kind of mode of vibration of each piezoelectric element in the present embodiment, that is,
Each piezoelectric element is of reciprocating vibration, and in synchronization, the direction of vibration of each piezoelectric element is all identical.
But in this mode of vibration, vibration in the same direction can make vibratory output superposition so that whole radiating module produces repeatedly
Life is rocked, and, vibrational energy consumes on the securing means, using insufficient, along with air-out direction is with piezoelectric element
Direction of vibration changes, and therefore wind-force relatively dissipates, so that wind-force is less.
Therefore, in order to reduce these problems as far as possible, so that the swaying direction of each stator is to different directions.Tool
Body asks for an interview following specific embodiment.
As shown in figure 8, embodiments providing the 3rd embodiment of radiating module, for having setting of radiation tooth
Standby, the radiating module of the present embodiment includes at least two vibration units 801 and fixing device 802.For example, at least two in Fig. 8

Moving cell 8014 ..., vibration unit 801m, wherein, m >=2.
Wherein, each vibration unit of the present embodiment includes piezoelectric element and solid piece, piezoelectricity unit in each vibration unit
Part is connected with one end of the solid piece in this vibration unit.Fixing device 802 is connected with the piezoelectric element in each vibration unit,
For fixing described radiating module.
Each piezoelectric element of the present embodiment all passes to alternating current, and described alternating current makes each described piezoelectric element same
One moment is respectively to first direction and second direction vibration；Described first direction and described second direction are contrary.
In the present embodiment, each piezoelectric element is of reciprocating vibration in the presence of alternating current, and wherein, each piezoelectric element exists
Synchronization respectively to first direction and second direction vibration, therefore each solid piece in synchronization also respectively to first direction
Swing with second direction.For example, shown in Fig. 8, at a time, piezoelectric element 8011, piezoelectric element 8013 and piezoelectric element 801
M vibrates to the right, and piezoelectric element 8012 and piezoelectric element 8014 vibrate to the left.And in subsequent time, each piezoelectric element is permissible
Vibrate in the opposite direction.
In the present embodiment, alternating current can be periodic signal, and now, each piezoelectric element is periodically of reciprocating vibration.
In the present embodiment, can also pass through to adjust frequency or the amplitude of alternating current, or the size of solid piece or piezoelectric element, real
The regulation of existing wind-force size.
By technique scheme, provide a kind of mode of vibration of each piezoelectric element in the present embodiment, that is,
Each piezoelectric element is of reciprocating vibration, and in synchronization, each piezoelectric element is respectively to two contrary direction vibrations.Can
See, compared with the embodiment shown in Fig. 7, in the present embodiment, whole piezoelectric elements are not to same direction vibration, therefore vibratory output
Relatively small, the situation that therefore whole radiating module rocks repeatedly has slowed down.And vibrational energy is not on the securing means
Consume, vibrational energy utilizes more abundant, along with air-out direction has subtracted with the situation of the direction of vibration change of piezoelectric element
Slow, therefore wind-force is higher.
In fact, the present embodiment one kind compares preferably, in synchronization, to two contrary direction vibrations
The number of piezoelectric element is of substantially equal.So that vibratory output can be cancelled out each other as far as possible.For example, when the piezoelectricity unit of the present embodiment
When the number of part is even number, then equal to the number of first direction and the piezoelectric element of second direction vibration.When the present embodiment
When the number of piezoelectric element is odd number, then differ one to the number of first direction and the piezoelectric element of second direction vibration.Under
Face is described separately both concrete conditions.
The first situation, the radiating module in the present embodiment includes 2n described vibration unit；Described n >=1.Namely
Say, the number of the vibration unit in the present embodiment is even number, and therefore the number of piezoelectric element is even number.
Wherein, each two vibration unit is one group；Described alternating current makes in synchronization, has and shake described in one in every group
The described piezoelectric element of moving cell vibrates to described first direction, and the described piezoelectric element in another described vibration unit is to institute
State second direction vibration.That is, having the piezoelectric element of n vibration unit in synchronization, radiating module to first party
To vibration, the piezoelectric element having n vibration unit vibrates to second direction.Now vibratory output is cancelled out each other, and radiating module will not
Situation about repeatedly rocking occurs.And vibrational energy does not consume on the securing means, vibrational energy, using more abundant, is added
Air-out direction is fixed, and will not change with the change of direction of vibration, and therefore wind-force compares concentration, and wind-force is higher.Invention
People finds, in the case that piezoelectric element number is equal, this mode of vibration wind-force compares the vibration side shown in Fig. 7 through experiment
Formula, wind intensity can increase 7.5%, and amplitude decreases 3 times.
Two kinds of preferred mode of vibrations of this mode of vibration are described by Fig. 9 and Figure 10 separately below.
For example shown in Fig. 9, n is specially 4 that is to say, that the radiating module in the present embodiment includes 8 vibration units: shakes
Moving cell 8011, vibration unit 8011, vibration unit 8012, vibration unit 8013, vibration unit 8014, vibration unit 8015,
Vibration unit 8016, vibration unit 8017 and vibration unit 8018.In fig .9, vibration unit 8011 and vibration unit 8012 are
One group, vibration unit 8013 and vibration unit 8014 are one group, and vibration unit 8015 and vibration unit 8016 are one group, and vibration is single
Unit 8017 and vibration unit 8018 are one group.In synchronization, in each group, there is the piezoelectric element of a vibration unit to first
Direction (being specially to the right in Fig. 9) vibration, the piezoelectric element of a vibration unit shakes to second direction (being specially to the left in Fig. 9)
Dynamic.For example in including the group of vibration unit 8011 and vibration unit 8012, the piezoelectric element of vibration unit 8011 vibrates to the right,
Therefore drive the solid piece of vibration unit 8011 to swing to the right, and the piezoelectric element of vibration unit 8012 vibrates to the left, therefore carries
The solid piece of dynamic vibration unit 8012 swings to the left.
And in fig .9, two vibration units in each group are adjacent, for example, including vibration unit 8011 and vibration is single
In the group of unit 8012, vibration unit 8011 and vibration unit 8012 adjacent that is to say, that vibration unit 8011 and vibration unit
Other vibration units are not had between 8012.Solid piece due to vibration unit 8011 swings to the right, the consolidating of vibration unit 8012
Body piece swings to the left, therefore this two vibration unit air-out upwards.
It can be seen that in this mode of vibration shown in Fig. 9, the direction of vibration of the adjacent piezoelectric element of two vibration units
On the contrary, the swaying direction of therefore solid piece is contrary, and vibratory output is cancelled out each other, and radiating module is not in situation about repeatedly rocking,
And vibrational energy does not consume on the securing means, vibrational energy utilizes more abundant, along with the air-out direction of radiating module
Fixing, will not change with the direction of vibration of piezoelectric element, therefore wind-force compares concentration, and wind-force is higher.
For example shown in Figure 10, n is specially 4 that is to say, that the radiating module in the present embodiment includes 8 vibration units: shakes
Moving cell 8011, vibration unit 8011, vibration unit 8012, vibration unit 8013, vibration unit 8014, vibration unit 8015,
Vibration unit 8016, vibration unit 8017 and vibration unit 8018.In Fig. 10, vibration unit 8011 and vibration unit 8012 are
One group, vibration unit 8013 and vibration unit 8014 are one group, and vibration unit 8015 and vibration unit 8016 are one group, and vibration is single
Unit 8017 and vibration unit 8018 are one group.In synchronization, in each group, there is the piezoelectric element of a vibration unit to first
Direction (in Figure 10 be specially to the right) vibration, the piezoelectric element of a vibration unit is to second direction (being specially to the left in Figure 10)
Vibration.
And in Fig. 10, the vibration unit belonging to the piezoelectric element to first direction vibration in each group is located at first
Region, in each group to second direction vibration piezoelectric element belonging to vibration unit be located at second area, first area and
Second area is different.Specifically, vibration unit 8011, the pressure of vibration unit 8013, vibration unit 8015 and vibration unit 8017
Electric device all vibrates to first direction, and this four vibration units are located at first area, and vibration unit 8012, vibration unit
8014th, the piezoelectric element of vibration unit 8016 and vibration unit 8018 all vibrates to second direction, and this four vibration units are located at
Second area, this two region differences, that is, there is no the part of overlap.Actually in Fig. 10, this two regions are adjacent.
It can be seen that in this mode of vibration shown in Figure 10, in synchronization, each due to first area and second area
The swaying direction of individual solid piece is contrary, and vibratory output is cancelled out each other, and radiating module is not in situation about repeatedly rocking, and vibrates
Energy does not consume on the securing means, and vibrational energy using more fully, fix, will not by the air-out direction along with radiating module
With the direction of vibration change of piezoelectric element, therefore wind-force compares concentration, and wind-force is higher.
Second situation, the radiating module in the present embodiment includes 2n+1 described vibration unit；Described n >=1.?
That is, the number of the vibration unit in the present embodiment is odd number, and therefore the number of piezoelectric element is odd number.
Wherein, in 2n vibration unit, each two vibration unit is one group；Described alternating current makes in synchronization,
The described piezoelectric element having a described vibration unit in every group vibrates to described first direction, in another described vibration unit
Described piezoelectric element vibrate to described second direction.That is, there being n vibration unit in synchronization, radiating module
Piezoelectric element vibrate to first direction, have the piezoelectric element of n vibration unit to second direction vibration.Now vibratory output phase
Mutually offset, radiating module is not in situation about repeatedly rocking.And vibrational energy does not consume on the securing means, vibrational energy
Amount, using more abundant, along with air-out direction is fixed, will not change with the change of direction of vibration, therefore wind-force compares
Concentrate, wind-force is higher.Two kinds of preferred mode of vibrations of this mode of vibration are described by Figure 11 and Figure 12 separately below.
For example shown in Figure 11, n is specially 4 that is to say, that the radiating module in the present embodiment includes 9 vibration units: shakes
Moving cell 8011, vibration unit 8011, vibration unit 8012, vibration unit 8013, vibration unit 8014, vibration unit 8015,
Vibration unit 8016, vibration unit 8017, vibration unit 8018 and vibration unit 8019.In fig. 11, vibration unit 8011 He
Vibration unit 8012 is one group, and vibration unit 8013 and vibration unit 8014 are one group, vibration unit 8015 and vibration unit
8016 are one group, and vibration unit 8017 and vibration unit 8018 are one group.In synchronization, in each group, there is a vibration single
, to first direction (being specially to the right in Figure 11) vibration, the piezoelectric element of a vibration unit is to second direction for the piezoelectric element of unit
(being specially to the left in Figure 11) vibration.And in this moment, in described 2n+1 described vibration unit, except described 2n institute
State a described vibration unit outside vibration unit, that is, the vibration unit being not a group with any vibration unit, that is, vibrate
Unit 8019, both can be to first direction vibration it is also possible to vibrate to second direction.
And in fig. 11, two vibration units in each group are adjacent, for example, including vibration unit 8011 and vibration
In the group of unit 8012, vibration unit 8011 and vibration unit 8012 adjacent that is to say, that vibration unit 8011 and vibration unit
Other vibration units are not had between 8012.Solid piece due to vibration unit 8011 swings to the right, the consolidating of vibration unit 8012
Body piece swings to the left, therefore this two vibration unit air-out upwards.
It can be seen that in this mode of vibration shown in Figure 11, in addition to vibration unit 8019, adjacent two vibration units
Piezoelectric element direction of vibration contrary, therefore the swaying direction of solid piece is contrary, and vibratory output is cancelled out each other, and vibration unit
The vibratory output of 8019 generations is also smaller, and what therefore radiating module occurred rocks also very little, only little vibrational energy repeatedly
Amount consumes on the securing means, and vibrational energy using very fully, fix, will not be with pressure by the air-out direction along with radiating module
The direction of vibration change of electric device, therefore wind-force compares concentration, and wind-force is higher.
For example shown in Figure 12, n is specially 4 that is to say, that the radiating module in the present embodiment includes 9 vibration units: shakes
Moving cell 8011, vibration unit 8011, vibration unit 8012, vibration unit 8013, vibration unit 8014, vibration unit 8015,
Vibration unit 8016, vibration unit 8017, vibration unit 8018 and vibration unit 8019.In fig. 12, vibration unit 8011 He
Vibration unit 8012 is one group, and vibration unit 8013 and vibration unit 8014 are one group, vibration unit 8015 and vibration unit
8016 are one group, and vibration unit 8017 and vibration unit 8018 are one group.In synchronization, in each group, there is a vibration single
, to first direction (being specially to the right in Figure 12) vibration, the piezoelectric element of a vibration unit is to second direction for the piezoelectric element of unit
(being specially to the left in Figure 12) vibration.And in this moment, in described 2n+1 described vibration unit, except described 2n institute
State a described vibration unit outside vibration unit, that is, the vibration unit being not a group with any vibration unit, that is, vibrate
Unit 8019, both can be to first direction vibration it is also possible to vibrate to second direction.
And in fig. 12, the vibration unit belonging to the piezoelectric element to first direction vibration in each group is located at first
Region, in each group to second direction vibration piezoelectric element belonging to vibration unit be located at second area, first area and
Second area is different, that is, does not have the part of overlap.Specifically, vibration unit 8011, vibration unit 8013, vibration unit
8015 and the piezoelectric element of vibration unit 8017 all vibrate to first direction, this four vibration units are located at first area, and shake
Moving cell 8012, the piezoelectric element of vibration unit 8014, vibration unit 8016 and vibration unit 8018 all vibrate to second direction,
This four vibration units are located at second area, this two region differences.
It can be seen that in this mode of vibration shown in Figure 12, in synchronization, each due to first area and second area
The swaying direction of individual solid piece is contrary, and vibratory output is cancelled out each other, and the vibratory output that vibration unit 8019 produces is also smaller, therefore
Also very little, the only little vibrational energy that repeatedly rocks that radiating module occurs consumes on the securing means, vibrational energy profit
With very fully, the air-out direction along with radiating module is fixed, will not change with the direction of vibration of piezoelectric element, therefore wind-force
Relatively concentrate, wind-force is higher.
In view of minimizing vibration transmission, in second situation, that is, the quantity of vibration unit be odd number when, permissible
So that a described vibration unit in addition to described 2n described vibration unit is located at the center of module.For example in Figure 11 and Tu
In 12, setting vibration unit 8019 is located at the center of whole module.Or when radiating module is fixed on the equipment with radiation tooth
When upper, a described vibration unit in addition to described 2n described vibration unit was located at the center of whole equipment, thus entering one
Step reduces vibratory output.
It should be noted that, in Fig. 9 and Figure 11, even if there being a piece of or multi-disc vibration unit inefficacy, do not interfere with yet
To other vibration units.Have a look Fig. 7 first, in synchronization, the piezoelectric patches of each vibration unit shakes to same direction
Dynamic.And this mode is compared with respect to the mode of vibration in the 3rd embodiment of radiating module, in vibration unit number identical
In the case of, air-out effect is poor.And if in order to increase wind-force, then need to reduce the spacing between vibration unit, if now having one
Individual vibration unit lost efficacy, then be likely to as shown in figure 13 so that adjacent vibration unit is occurred with the vibration unit losing efficacy
Collision, not only can produce noise, or even two neighboring vibration unit also can be accelerated to lose efficacy, and whole radiating module all can occur quickly
Lost efficacy.
And in the radiating module shown in Fig. 9 and Figure 11, in addition to vibration unit 8019, even if a piece of vibration unit loses
Effect, also will not be collided with remaining vibration unit.And compare Fig. 7, wind-force is higher.
