(example 1)

For the linear drive apparatus in the utility model example 1, describe with reference to drawing.Taking drawing top as upper and lower as under describe.

Linear drive apparatus 1 shown in Fig. 5 for display unit with the electronic equipment of contact panel function or use the electronic equipment such as input equipment of operation keys.In the main body of these electronic equipments, be built-in with in advance the vibrating device of linear drives mode, operator presses while carrying out input information with finger or manipulation pen, and finger or manipulation pen are returned in vibration, transmit the sensation of certain complete operation to operator.

As shown in Fig. 1～Fig. 7, the linear drive apparatus 1 of this example 1, comprises driving shaft 9, micro-vibration generating unit material 8, framework 3 and moving body 14.

For making driving shaft 9 can carry out axial free displacement, framework 3 must support at least one party of driving shaft 9 or micro-vibration generating unit material 8.In illustrated example, for making driving shaft 9 can carry out axial free displacement, framework 3 is supporting driving shaft 9.

Meanwhile, in mode 1 shown in Fig. 1～Fig. 7, in one end of driving shaft 9 (being lower end), connect micro-vibration generating unit material 8, presenting the structure that micro-vibration generating unit material 8 is only supported by framework 3 by driving shaft 9.

Moving body 14, by the axial displacement of driving shaft 9, can be dynamically connected with driving shaft 9 in the axial direction of driving shaft 9, carries out axially coming and going mobile along driving shaft 9.

In mode 1 shown in Fig. 1～Fig. 7, framework 3 is upper end open tubular, and the end face of this upper part contacts with the lower surface 2b of electronic equipment main body.And, owing to structurally possessing the lid 4 of closed upper end opening, so lid 4 also can be regarded a part for framework as.As shown in Figure 5, lid 4 possesses the lid opening place of several fixed intervals in a circumferential direction.

The bottom central part of framework 3 is divided and the middle body of the lid 4 of corresponding position, has separately through hole.In each through hole, be inserted with driving shaft 9 by sleeve pipe 10,5.

Like this, in diagramatic way 1, framework 3 bottom central part are divided with the connecting line at the center of the through hole of lid 4 middle bodies just becomes the structure vertical with lid 4 with framework 3 bottom surfaces.

The drive part that moving body 14 is moved, is made up of micro-vibration generating unit material 8 and driving shaft 9.

Flexible thin plate 7a, 7b that micro-vibration generating unit material 8 is installed by elastic sheet 6 with at least one side of elastic sheet 6 form.In illustrated example, be fixed with respectively flexible thin plate 7a, 7b at the upper and lower surface of elastic sheet 6, become bimorph type.

By applying driving voltage to flexible thin plate 7a, 7b, cause flexible thin plate 7a, 7b flexible, be fixed with middle body and the marginal portion of the elastic sheet 6 of flexible thin plate 7a, 7b, carry out relative displacement to the normal direction of elastic sheet 6.Affected by this, micro-vibration generating unit material 8 is deformed into a bowl type.

Piezoelectric and electrostriction material that flexible thin plate 7a, 7b are adhering to electrode material by two sides form.Electrode material uses copper or copper alloy etc.Piezoelectric, electrostriction material use lead zirconate titanate, barium titanate, plumbous magnesium-niobate etc.Flexible thin plate 7a, 7b are circle or polygonal.

Elastic sheet 6 uses copper or copper alloy elastomeric material.Although not do not show in diagram, also can be only flexible thin plate 7a or 7b be arranged on to the one side of elastic sheet 6, become single piezoelectric chip.And elastic sheet 6 preferably adopts the profile corresponding with flexible thin plate 7a or 7b, but not correspondingly also can.

Be fixed on elastic sheet 6 with will stretch thin plate 7a, the 7b such as conductive adhesive, connect up respectively on the two sides of micro-vibration generating unit material 8, be used for flexible thin plate 7a, 7b to apply voltage.Though not diagram, these connections are to drive control part.

The lightweight hardness of driving shaft 9 is high, uses the material such as charcoal base, is cylindricality.

One end of driving shaft 9 connects micro-vibration generating unit material 8.In illustrated example, the axle top of driving shaft 9 one end is fixed on the central shaft of micro-vibration generating unit material 8.Fixed form can adopt adhesive that the surface on axle top is fixed on the surface of micro-vibration generating unit material 8.In illustrated example 1, just make the coupling part chap of driving shaft 9 and micro-vibration generating unit material 8 just because of this adhesive.Driving shaft 9 itself is identical to the thickness of top end surface, or the area of top end surface is less than the sectional area of driving shaft 9 main parts.The head portion of driving shaft 9 attenuates, and can make the area of the micro-vibration generating unit material 8 that contributes to practical distortion increase.

In addition, except the head portion of driving shaft 9 being fixed on to the structure on micro-vibration generating unit material 8, can also on micro-vibration generating unit material 8, open through hole, be used for fixing the lateral parts on axle top.

As mentioned above, driving shaft 9 is supported by framework 3 by sleeve pipe 5,10, free displacement on direction of principal axis.

Sleeve pipe the 5, the 10th, the elastomeric material of making for rubber of supporting driving shaft 9 etc., has the centre bore that can insert driving shaft 9 above.

Be arranged on the sleeve pipe 5 at the central part through hole place of lid 4, be bonded and fixed on the medial surface of position, top centre bore of driving shaft 9, on this driving shaft 9, the contrary other end is fixed on micro-vibration generating unit material 8.

And be arranged on the sleeve pipe 10 at framework 3 through hole places, bottom central part position, and at the medial surface of centre bore, not to bond fixingly with driving shaft 9, but only rely on outside pressurization to be supported.

By this structure, there is axial displacement in driving shaft 9, but driving shaft 9 itself can not move at a distance by this displacement as moving body 14.

Moving body 14, by the axial displacement of driving shaft 9, can be dynamically connected with driving shaft 9 in the axial direction of driving shaft 9.

In example 1, moving body 14 is by being movably connected to the annular brace portion 11 on driving shaft 9, the annular hammer 14a of portion, the 14b that separate with support portion 11, forming with the plate body 13 that the 14a of hammer portion, 14b are connected with support portion 11.

In the axial direction of driving shaft 9, the annular support portion 11 of movable connection, can adopt the mode of frictional connection to connect.

Frictional connection mode 1 refers to, by using annular tightening member 12, from periphery clamping annular brace portion 11, makes annular brace portion 11 frictional connections on driving shaft 9.

Example shown in Fig. 8 is a wherein example.Annular brace portion 11 is combined by two identical dividing body 11a and 11b of shape.On the correspondence position of driving shaft 9, there is the opening 11c and the 11d that hold driving shaft 9 in each dividing body 11a and 11b.When clamping driving shaft 9 and assemble with dividing body 11a and 11b, between the composition surface 11e of dividing body 11a and the composition surface 11f of dividing body 11b, can form space.Like this, by annular tightening member 12 from periphery clamping, annular brace portion 11 just can frictional connection to driving shaft 9.

Dividing body 11a and the 11b of composition support portion 11, can use such as stainless steel and other metal materials.Can improve like this durability of support portion 11.

The annular tightening member 12 that is arranged on the periphery of annular brace portion 11, from outside to inside support portion 11 is clamped on the radial direction centered by driving shaft 9, can adopt helical spring.

In addition, also can between composition surface 11e and composition surface 11f, fill heat-shrinkable resin, utilize the thermal shrinkage force of heat-shrinkable resin to carry out fastening.

Meanwhile, the contact portion of driving shaft 9 and support portion 11 preferably contacts as Fig. 8 section is depicted as, the frictional connection state that so easy maintenance is stable.

The mode 2 of frictional connection refers to there is the support portion through hole inserting for driving shaft 9 at the central part of support portion 11, can in this support portion through hole, fill the heat-shrinkable resin after thermal contraction.

The thermal shrinkage force of the heat-shrinkable resin of filling in the through hole of support portion, becomes the frictional force of driving shaft 9 being pressurizeed from outside.

On support portion 11, be fixed wtih plate body 13 in enclose, the periphery of plate body 13 is connected with the annular hammer 14a of portion, 14b.

In diagramatic way, the peripheral top and bottom of plate body 13, are installed with respectively the annular 14a of hammer portion, 14b.

The upper surface (with the reciprocal other end front, one end of driving shaft 9) of the 14a of hammer portion is above furnished with jut 15.In illustrated mode, on the lid 4 of framework 3, there is the opening of 3 place's lids,, form and amount to 3 juts 15 separately on corresponding position at them.

Jut 15 also can be swelled upward and be formed by the upper surface of the above-mentioned 14a of hammer portion above itself.Or on the upper surface of the superincumbent hammer 14a of portion, connecting hemisphere also can.On the upper surface of the superincumbent hammer 14a of portion, design a groove, in this groove, connect an orbicule and also can.Formation method needn't stick to specifically described above.

By forming the jut 15 arranging on the upper surface of the 14a of hammer portion above of moving body 14, as shown in Fig. 1～Fig. 7, knock the lower surface 2b of electronic equipment main body when moving above driving shaft 9 at moving body 14, moving body 14 is not with face but removes shock with putting.Can make like this to clash into and focus on a bit above, can improve input operation time, vibration is returned to finger or manipulation pen, is transmitted the sensation of certain complete operation to operator, improves tactile feedback effect.

The form of jut 15 has following several.

In the form 1 of jut 15, in the time that moving body 14 moves to the top of driving shaft 9, the summit of jut 15 at least reaches the height identical with framework 3 top end faces, from framework 3, exposes.

In illustrated form, as shown in Figure 2, Figure 4 shows, in the time that moving body 14 moves to the top of driving shaft 9, the apex height of jut 15 is highly identical with the upper surface (with the reciprocal other end front, one end of driving shaft 9) of lid 4.

In Fig. 2, Fig. 4, the upper level of lid 4 is identical with the height of framework 3 upper end end faces (with the reciprocal other end front, one end of driving shaft 9).Therefore, the equal height that the summit of jut 15 reaches framework 3 upper end end faces (end face of the framework 3 of the other end) can expose from framework 3.

As shown in Figure 2, Figure 4 shows, in the time being equipped with the lower surface 2b of electronic equipment main body of linear drive apparatus of this example 1 and the upper end end face of framework 3 and contacting, as mentioned above, the apex height of jut 15 reaches the height identical with framework 3 upper end end faces, and the summit of jut 15 is with the lower surface 2b of an impingement of electrons equipment body.

Like this, in the linear drive apparatus of this example, moving body 14 is not with face, but removes the lower surface 2b of impingement of electrons equipment body with point, can make to clash into concentrate on a bit.Like this, while carrying out input operation, finger or manipulation pen are returned in vibration, transmit the sensation of certain complete operation to operator, can improve tactile feedback effect.

In the form 2 of jut 15, in the time that moving body 14 moves to the top of driving shaft 9, can reach the summit that makes jut 15 at least from the form of the upper end head face hump of framework 3.

By the form 2 of this jut 15, can further improve input operation time, finger or manipulation pen are returned in vibration, transmit the sensation of certain complete operation to operator, improve tactile feedback effect.

One of linear drive apparatus 1 to this example 1 example action below describes.

Micro-vibration generating unit material 8 applies driving voltage to flexible thin plate 7a, and the thickness direction of flexible thin plate 7a extends, horizontal direction is shunk, but elastic sheet 6 does not produce such stretching.Therefore, the mid portion of micro-vibration generating unit material 8, to top offset, marginal portion to bottom offset, produces distortion.Driving voltage waveform is different triangular wave etc. square wave, sawtooth waveforms, rise time and the fall time of tens of kHz left and right cycle.

The driving shaft 9 that one end is fixed on the centre position of micro-vibration generating unit material 8 is also moved upward, and the moving body 14 being connected on driving shaft 9 is also moved upward.

Micro-vibration generating unit material 8 produces after predetermined distortion, and driving voltage sharply declines, and the distortion of micro-vibration generating unit material 8 is subject to the elastic force of elastic sheet 6 and recovers rapidly.

Meanwhile, driving shaft 9 is also got back to origin-location, and moving body 14 does not but move rapidly downwards with driving shaft 9, but rests on existing position.

As a result, moving body 14 slightly moves upward.

Come and go asymmetric moving axially along with driving shaft 9 is this, while coming and going each time, moving body 14 is moved upward 1 μ m～number μ m.

Repeat above-mentioned this action with the cycle of tens of kHz.

In addition, when moving body 14 is moved down, for making driving shaft 9 carry out contrary moving axially up and down, the telescopic material 7b of micro-vibration generating unit material 8 is applied to same driving voltage.Like this, moving body 14 comes and goes mobile along axially doing on driving shaft 9 of driving shaft 9.

Through so once or moving body 14 for several times in axial the moving up of driving shaft 9, the summit of jut 15 produces and clashes into the lower surface 2b of electronic equipment main body that is connected to framework 3 upper end end faces.Like this, when the summit of jut 15 and moving body 14 move to the top of driving shaft 9, the height of the upper surface of lid 4 or framework 3 upper end end faces is identical, from framework 3, exposes.Or when moving above driving shaft 9, present the form that at least the upper end end face from framework 3 protrudes at moving body 14.

In this example 1, the 14a of hammer portion is connected with support portion 11 by plate body 13.The summit of the jut 15 configuring on the upper surface of the 14a of hammer portion being connected with support portion 11 by plate body 13, strike the lower surface 2b of electronic equipment main body, therefore, in the time carrying out input operation, finger or manipulation pen are returned in vibration, transmit the sensation of certain complete operation to operator, improve tactile feedback effect.

Meanwhile, plate body 13 can not be singly a plate, can be also the leaf spring by being connected from support portion 11 along the outward extending support arm of radial direction and between the 14a of hammer portion.At this moment, the effectively lower surface 2b of impingement of electrons equipment body of the summit of jut 15.Like this, while carrying out input operation, finger or manipulation pen are returned in vibration, transmit the sensation of certain complete operation to operator, improve tactile feedback effect.

When the 14a of hammer portion, 14b overlook, the rounded or polygonal of profile.

The 14a of hammer portion, 14b use the large material of tungsten alloy isodensity, can have larger weight like this in the time of same volume, and the impact in the time of the impingement of electrons equipment body lower surface 2b of the summit of jut 15 can be larger.Therefore, plate body 13 also can adopt parts resilient, that support portion 11 and the 14a of hammer portion, 14b elasticity are linked together.For example, can adopt above-mentioned leaf spring as plate body 13.

In illustrated form, the upper and lower surface of plate body 13 is installed with respectively the 14a of hammer portion, 14b, but also the 14a of hammer portion above can be only installed.In illustrated form, for the summit that makes jut 15 impact in the time striking the lower surface 2b of electronic equipment main body increases, at the upper and lower surface of plate body 13, the 14a of hammer portion, 14b are installed respectively.

According to this example 1, jut 15, with the lower surface 2b of an impingement of electrons equipment body, concentrates on some shock.Therefore, in this example, on the upper surface of the 14a of hammer portion, be provided with 3 place's juts 15, but also place's jut 15 can be only set on the upper surface of the 14a of hammer portion.

In this example 1, moving body 14 separates with the 14a of hammer portion, 14b with support portion 11, and the two is connected by plate body 13.But also can make moving body 14 as support portion 11, become several dividing bodies, by annular tightening member clamping, moving body entirety together with driving shaft 9 frictional connections.

In this example 1, what micro-vibration generating unit material 8 adopted is the plate-shaped member such as bimorph or single piezoelectric chip, but also can adopt the parts of lamination-type.Now, framework 3 can only support micro-vibration generating unit material 8.

(example 2)

Use Fig. 9～Figure 11 to describe adoptable other mode examples of the utility model.

The building block identical with the example 1 that uses Fig. 1～Fig. 8 to introduce, represents, the description thereof will be omitted with same symbol herein.

In the example of Fig. 9～Figure 11, the jut on the upper surface of the upper plane set-hammer 14a of portion of formation moving body 14 becomes tabular.Therefore, the moving body 14 including the 14a of hammer portion, 14b moves above driving shaft 9, and when the lower surface 2b of impingement of electrons equipment body, moving body 14 clashes into the face of flat jut 16.

In illustrated mode, on 4 angles of the 14a of hammer portion, there is respectively flat jut 16.Meanwhile, in the upper end of framework 3, be furnished with to overlook and be criss-cross lid 4.Above lid 4, Pasting double faced adhesive tape 20 etc., by double faced adhesive tape 20, linear drive apparatus 1 is installed on the lower surface 2b of electronic equipment main body.In the time of the lower surface 2b of the upper side plane impingement of electrons equipment body of flat jut 16, lid 4 can be absorbed in the groove forming between 4 juts 16.

Identical with example 1, the moving body 14 of the linear drive apparatus 1 of this example 2 also makes to do on driving shaft 9 round mobile in the axial direction of driving shaft 9.Moving body 14 moves to the top of driving shaft 9, and after the lower surface 2b of impingement of electrons equipment body, while movement to the below of driving shaft 9, the bottom of moving body 14 can be bumped against with the bottom surface of framework 3.Now can send unnecessary bruit de froissement.

In example 2, sound proof part material 21 is equipped with in the bottom of framework 3.By on the bottom surface in moving body 14 framework 3 relative with the lower surface of driving shaft 9, sound proof part material 21 being installed, can reduce the generation of unnecessary bruit de froissement.

The object of sound proof part material 21 is installed, and is to move to the below of driving shaft 9 when moving body 14, when the bottom surface of its underpart and framework 3 bumps, reduces the generation of bruit de froissement.Therefore, sound proof part material 21 is installed between the lower surface of moving body 14 and the bottom surface of framework 3.

Therefore, except adopting the bottom surface in framework 3 to install the mode of sound proof part material 21, can also adopt when sound proof part material is installed in the bottom surface of framework 3, at the lower surface of moving body 14, with example as shown in Figure 9, the mode of sound proof part material 21 is installed at the lower surface of the 14b of hammer portion of downside.

As long as it is just passable that sound proof part material material 21 can achieve the above object.The thickness that for example, can adopt the synthetic resin such as polyethylene terephthalate to make is the board of 01mm left and right.

Meanwhile, in this example 2, framework 3 has the inside and outside space of framework 3 of connection.

In the inside of framework 3, with the outside structure not being connected, in the time that moving body 14 comes and goes movement in the axial direction of driving shaft 9, the air of framework 3 inside cannot be discharged to outside.Like this will be to the round mobile air drag that produces of moving body 14.Be subject to after this air drag, the round translational speed of moving body 14 can reduce, and the impact that moving body 14 moves to driving shaft 9 tops while shock with the lower surface 2b of electronic equipment main body can weaken.

In example 2, framework 3 has the inside and outside gap of framework 3 of connection.Like this, as shown in figure 11, moving body 14 is no matter rising while still declining, and the inside and outside air of framework 3 can flow.This can make that moving body 14 is come and gone to the mobile air drag producing and diminish compared with the inside and outside structure not being connected of framework 3.Therefore, moving body 14 is subject to air drag impact, and the amplitude that translational speed reduces also can diminish.Can make like this impact of moving body 14 in the time of the lower surface 2b of impingement of electrons equipment body become large, in the time carrying out input operation, vibration be passed back to finger or manipulation pen, transmit the sensation of certain complete operation to operator, improve tactile feedback effect.

In illustrated example, as being communicated with the inside and outside gap of framework 3, offer through hole 23a, the 23b of ventilative use in the bottom surface of framework 3, offer breach 24a, 24b, 24c, the 24d of ventilative use on the top of framework 3.Breach 24a～24d, by combined with framework 3 upper surfaces and electronic equipment main body lower surface 2b, can play the effect that is communicated with the inside and outside gap of framework 3.

As shown in Figure 11 (a), represent that with arrow moving body 14 is moved upward, air flows at the inside and outside of framework 3.That is to say that the air between the upper surface of moving body 14 and the lower surface 2b of electronic equipment main body, by breach 24a～24d, successfully flows to framework 3 outsides.Meanwhile, between the lower surface of moving body 14 and the bottom surface of framework 3, air, by through hole 23a, 23b, successfully flows into from the outside of framework 3.Like this, the deceleration that moving body 14 can be brought by air drag hardly, clashes into the lower surface 2b of electronic equipment main body.

On the other hand, as shown in Figure 11 (b), represent that with arrow moving body 14 moves downwards, air flows at the inside and outside of framework 3.That is to say that the air between the lower surface of moving body 14 and the bottom surface of framework 3, by breach 24a～24d, successfully flows to framework 3 outsides.Meanwhile, the air between the upper surface of moving body 14 and the lower surface 2b of electronic equipment main body, by through hole 23a, 23b, successfully flows into from the outside of framework 3.Like this, the significantly deceleration that moving body 14 is not brought by air drag can, completes decline.Therefore,, by the switching driving voltage that carries out introducing in example 1, the significantly deceleration that moving body 14 is not brought by air drag can, moves up and down.

Like this, in the time that framework 3 has the inside and outside gap of circulation framework 3, moving body 14 just can not affected by large air drag in framework 3, moves up and down.

Therefore, when moving body 14 moves to driving shaft 9 belows, while shock with the bottom surface of framework 3, not affected by large air drag, clash into.

Like this, in the time that framework 3 has the structure that is communicated with the inside and outside gap of framework 3, preferably described above, between the lower surface of moving body 14 and the bottom surface of framework 3, clamp sound proof part material 21.Now, corresponding with position, the shape of the through hole 23a, the 23b that exist on framework 3 bottom surfaces, on sound proof part material 21, be preferably also provided with through hole 22a, the 22b of ventilative use.Like this, even if sound proof part material 21 has been installed, also can be as shown in figure 11, along with moving up and down of moving body 14, air flows inside and outside framework 3.

As mentioned above, the object that is communicated with the inside and outside gap of framework 3 being set, is for reducing the moving body 14 that comprises the 14a of hammer portion, 14b at air drag that framework 3 is interior to be produced while moving up and down along driving shaft 9.Therefore,, as long as can reach this object, gap can be not limited to above-mentioned through hole 23a, 23b and breach 24a～24d, but can adopt various forms and structure.

Meanwhile, can also make moving body 14 itself there is the structure that reduces air drag.For example, can, at the flat of flat jut 16, offer through hole from forming the 14a of hammer portion of moving body 14 and/or the upper surface of 14b to lower surface, make moving body 14 become the structure of the air-vent with up/down perforation.The periphery of the moving body 14 that can also form on the 14a of hammer portion and/or 14b is offered from top to bottom, the air channel of above-below direction, by this groove, possesses and makes the upwards mobile structure in below of air.

These air-vents or ventilating groove, make the air can be between the upper surface of moving body 14 and the lower surface 2b of electronic equipment main body, flow swimmingly between the lower surface of moving body 14 and the bottom surface of framework 3.Like this, moving body 14 is not affected by large air drag can, moves up and down.

(example 3)

In example 1 shown in Fig. 1～Figure 11,2, the lower end of driving shaft 9 is connecting micro-vibration generating unit material 8, and micro-vibration generating unit material 8 is only supported by framework 3 by driving shaft 9.

The method that this example 3 shown in Figure 12 adopts is that micro-vibration generating unit material 8 is fixed in framework 3 by the circumferential equidistant point of marginal position.Described in example 1, the thin plates such as flexible thin plate 7a, the 7b that micro-vibration generating unit material 8 configures by elastic sheet 6 with at least one side of elastic sheet 6 form, and are deformed into a bowl type by apply driving voltage on flexible thin plate 7a, 7b.

In the mode shown in Figure 12 (a), framework 3 is overlooked rectangular tubulose, and micro-vibration generating unit material 8 is overlooked rounded.

Framework 3 3a places, lower end, tubulose position, interior peripheral edge is arranged on the top of peripheral edge, as the standing part 3b of micro-vibration generating unit material 8.

Micro-vibration generating unit material 8 is fixed on marginal portion 8a on the standing part 3b of framework 3 with point (small size).

In the example of Figure 12 (a), framework 3 sees from below and is square, and micro-vibration generating unit material 8 looks that to only have the standing part 3b that is arranged on framework 3 everywhere of marginal portion 8a upper, rounded.

By elastic sheet 6 is protruded to the periphery of flexible thin plate 7a, 7b, can form to put the marginal portion 8a on the standing part 3b that is fixed on framework 3.In flexible thin plate 7a, 7b, elastic sheet 6, the parts that make to be fixed on the standing part 3b of framework 3 protrude laterally, form marginal portion 8a, can more easily carry out electric wire wiring.

Because micro-vibration generating unit material 8 is directly fixed in framework 3, can obtain stable driving by micro-vibration generating unit material 8.And marginal portion 8a is not all but is fixed with point, the slight vibration that therefore micro-vibration generating unit material 8 produces is absorbed by framework 3, and the resistance that distortion is subject to is little, and the driving force that micro-vibration generating unit material 8 produces is very large.And, compared with example 1, the removable heavier 14a of hammer portion, 14b.

And bottom 3a becomes the standing part 3b of inside edge higher than outer ledge.Therefore, by making the difference of height of standing part 3b be greater than the thickness of micro-vibration generating unit material 8, can make micro-vibration generating unit material 8 not exceed the scope of framework 3 lower end 3a, be surrounded by framework 3.Like this, after linear drive apparatus 1 completes with assembling in assembling process, its micro-vibration generating unit material 8 is not vulnerable to the destruction of external force.

Meanwhile, except above-mentioned situation, framework 3 and micro-vibration generating unit material 8 other combination of shapes in addition in this example.

For example, Figure 12 (b) is contrary with Figure 12 (a), and framework 3 is rounded, and micro-vibration generating unit material 8 is square.

In Figure 12 (c), framework 3 and micro-vibration generating unit material 8 are all square.Like this, the foursquare corner edge 8a of micro-vibration generating unit material 8 is placed on the standing part 3b at square edge place of framework 3.

In Figure 12 (d), framework 3 is octangle, and micro-vibration generating unit material 8 is square.

This shape also can be regarded as carries out by the angle of foursquare framework 3 in Figure 12 (c) shape obtaining after chamfered.Therefore, framework 3 can not be also octangle, but the square of fillet.

Figure 12 (e) has changed the shape of micro-vibration generating unit material 8 in Figure 12 (d) as circle into.

In Figure 12 (f), micro-vibration generating unit material 8 is not circular or square, but hexagon.This shape also can.

The shape of framework 3 and micro-vibration generating unit material 8 can have various combinations like this.

And, shown in this example 3, the marginal portion of micro-vibration generating unit material 8 is fixed in framework 3 in a circumferential direction equidistantly with point, is not only applicable to the structure of (with the reciprocal other end front, one end of driving shaft 9) configuration jut 15 on the upper surface of moving body 14.

For example, applicable equally for the structure that does not configure jut 15 on the upper surface of moving body 14.The moving body 14 of this structure comprises the camera lens supporter that can install by camera lens etc.At this moment, linear drive apparatus plays the effect of lens driving apparatus.

(example 4)

In above-mentioned example, only the mode of jut 15 impingement of electrons equipment body lower surface 2b is illustrated.In following this example 3, by controlling the driving voltage that micro-vibration generating unit material 8 is applied, can be in the first pattern: with the form of jut 15 impingement of electrons equipment body lower surface 2b, with the second pattern: jut 15 is the lower surface 2b of impingement of electrons equipment body not, switches and driving shaft 9 is done in the form moving up and down in the axial direction.

The position of Figure 13 to moving body 14 under these two kinds of patterns and time one of change example and are described.

Under the first pattern, by applying driving voltage, moving body 14 is moved upward (A) from reference position along driving shaft 9, the lower surface 2b (B) of the summit impingement of electrons equipment body of jut 15.Clash into for producing accurately, after shock occurs, continue to apply driving voltage, moving body 14 should continue to rise (C), but because moving body 14 clashes into the lower surface 2b of electronic equipment main body, therefore rests on (D) on existing position.

After the lower surface 2b of the summit impingement of electrons equipment body of jut 15, waveform by conversion driving voltage applies driving voltage, moving axially up and down of driving shaft 9 reversed, and moving body 14, along axially the moving down of driving shaft 9 (E), is got back to reference position.For making moving body 14 get back to exactly reference position, after returning to reference position, moving body 14 continues to apply driving voltage, and moving body 14 should continue to decline (F), but moving body 14 cannot be removed from reference position.Need to mobile larger distance due to moving body 14, therefore move each time the required time (T1) all longer.

And under the second pattern, the not lower surface 2b of impingement of electrons equipment body of jut 15, but driving shaft 9 is moved up and down in the axial direction.

Under this form, moving body 14 moves to the top of driving shaft 9 during from reference position (G), strike the waveform that (H) before the lower surface 2b of electronic equipment main body switches driving voltage on the summit of jut 15, make moving body 14 move (I) downwards.And then the waveform of switching driving voltage, make moving body 14 be moved upward (J).Repeat (I) and (J) after, make moving body 14 get back to reference position (K).

Moving body 14, in the summit of jut 15 does not arrive the scope of framework 3 upper end end face sustained heights, does not bump with the lower surface 2b of electronic equipment main body, within compared with the short period (T2) along driving shaft 9 axially do back and forth movement, produce vibration.This vibration is delivered to electronic equipment main body from framework 3.

For moving body 14 is not collided with framework 3 with the lower surface 2b of electronic equipment main body and on reference position, and keep continuously vibration, can make (G) required time and (K) required time be longer than (I) required time and (J) required time.

The first pattern, such as linear drive apparatus 1 is installed on electronic equipment, is used in operator and presses while carrying out input information with finger or manipulation pen, and vibration is passed back to finger or manipulation pen, transmits the sensation of certain complete operation to operator.

The second pattern, can be for the situation such as the incoming information of electronic equipment is passed to user by vibration.

Like this, linear drive apparatus 1 in this example 4, only by controlling the driving voltage that micro-vibration generating unit material 8 is applied, just can be in the first pattern: the form of jut 15 impingement of electrons equipment body lower surface 2b, with the second pattern: jut 15 is impingement of electrons equipment body lower surface 2b not, between the form that driving shaft 9 is moved up and down vertically, switches.That is:, when the switching cycle that moving body 14 is moved up and down along axially doing of driving shaft 9 is long period (T1), can realize the first pattern; During for the short period (T2), can realize the second pattern.

The electronic equipment that linear drive apparatus is housed of introducing in above-mentioned example, is not only limited in display unit with the electronic equipment of contact panel function or the electronic equipment that uses operation keys to input.For example, also can be built in the pointer for inputting on contact panel, or be built in wrist-watch.

And, except electronic equipment, can also be arranged in the body decoration such as ring or brooch, scarf product.

No matter be arranged in above-mentioned electronic equipment or body decoration product, the jut 15 being equipped with on moving body 14 is by impingement of electrons equipment body or body decoration product.Like this, in the time carrying out input operation, vibration can be passed back to finger or manipulation pen, complete operation really felt to pass to operator, raising tactile feedback effect.Simultaneously, the summit impingement of electrons equipment body of jut 15 or the mode of body decoration product main body, shock can make moving body 14 impingement of electrons equipment bodies or body decoration product main body time concentrates on a bit upper, can make like this tactile feedback effect be further enhanced.

Although the utility model with preferred embodiment openly as above, it is not for limiting the utility model, and any those skilled in the art, not departing from spirit and scope of the present utility model, can make possible variation and amendment.Therefore, every content that does not depart from technical solutions of the utility model, any amendment, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, within all falling into the protection range that the utility model claim defines.
