`
`WO Pat. No. WO 2011/013570 A1 to Miyazaki (“Miyazaki”) entitled “Vibrating Motor” renders obvious claims 1-20 of U.S. Patent
`No. 10,659,885 (the “’885 Patent”), in combination with other references and/or the knowledge of one of ordinary skill in the art, as set
`forth in the chart below and explained in Apple’s Preliminary Invalidity Contentions. This invalidity claim chart is based on Apple’s
`present understanding of the asserted claims and Taction Technology, Inc.’s (“Taction”) apparent construction of the claims, as set forth
`in Taction’s Preliminary Infringement Contentions. Apple is not adopting Taction’s apparent constructions, nor is Apple agreeing that
`any of Taction’s apparent constructions are correct. Apple reserves all rights to advance claim construction positions different from
`Taction’s apparent constructions. In addition to being explicitly disclosed in the prior art, each limitation of the asserted claims would
`have been inherent and/or obvious. By mapping claim language to this reference, Apple does not imply or admit that the claim language
`satisfies 35 U.S.C. § 112. To the extent any cell lacks citations to the charted reference, this should not be taken as an admission that the
`reference does not disclose the corresponding limitation but rather indicates that Apple does not presently intend to rely on the reference
`as disclosing the limitation based on Apple’s present understanding of the claim limitation.

`
`“The present invention relates to a vibrating motor provided with a movable portion that
`includes a permanent magnet and with a fixed portion that includes a coil.”
`Miyazaki at [0001]
`
`“The vibrating motor 1 according to the first embodiment of the present invention is a
`device that is built into a mobile device (not illustrated) or the like and is for imparting
`vibrations to this mobile device. As illustrated in FIG. 1, the vibrating motor 1 is made of
`a fixed portion 2, a movable portion 3 that vibrates relative to the fixed portion 2, and a
`spring member 4 that supports the movable portion 3 so as to enable vibration.”
`Miyazaki at [0013]
`
`“(9) The configuration of the vibrating motor 1 can increase a vibration amount of an
`object that the vibrating motor 1 causes to vibrate (for example, a mobile phone) while
`decreasing a Q value in vibration amount–frequency characteristics (relationship
`between the vibration amount of the object that the vibrating motor 1 causes to vibrate
`and a frequency of an input voltage) (increasing a frequency band wherein the vibration

`
`amount increases). By decreasing the Q value, unlike a situation—as in a situation of a
`high Q value—wherein the vibration amount does not increase unless an input voltage of
`an accurate frequency is input (situation wherein the vibration amount decreases rapidly
`when the input voltage shifts slightly from a resonance frequency), a large vibration
`amount can be obtained in a wider frequency band. As such, when an actual resonance
`frequency (f0) is shifted from a design value due to a manufacturing error, assembly
`error, or the like of a component of the vibrating motor 1, in this situation as well, a
`sufficient vibration amount can be obtained. Moreover, because the Q value can be
`decreased, a time from a resonant state to vibration stopping can be decreased. As such,
`stopping characteristics of the vibrating motor 1 can be improved.”

`
`“(Third Embodiment)
`FIG. 14 and FIG. 15 are each a diagram for describing one example of a mobile device
`using the vibrating motor according to any among the first and second embodiments of
`the present invention. Note that FIG. 15 is one cross section of a portion including the
`vibrating motor of FIG. 14.
`
`As illustrated in FIG. 14 and FIG. 15, the vibrating motor 1 (101) according to any
`among the first and second embodiments of the present invention can be used in a mobile
`phone 500 or the like. The mobile phone 500 is provided with the vibrating motor 1
`(101), a CPU 510 (see FIG. 15), and a display unit 520. The vibrating motor 1 (101) is
`disposed on a face on an opposite side of a side whereon the display unit 520 is disposed
`of the mobile phone 500. The display unit 520 is constituted by a panel of a touch-panel
`system and is configured so pressing a button portion 520a displayed on the display unit
`520 operates the mobile phone 500. Moreover, the vibrating motor 1 (101) is controlled
`by the CPU 510 to vibrate when it is sensed that the button portion 520a displayed on the
`display unit 520 is pressed, when the phone is set to vibrate for an incoming call, and the
`like.”

`resin 29. More specifically, as illustrated in FIG. 7, the planar coil 25 and the yoke 28 are
`integrated by a resin 29a, and the planar coil 26 and the wiring layer 27, formed
`respectively on an upper face and a lower face of the resin 29a, are covered by a resin

`invention. The yoke 28 is one example of the “lower-face-side yoke” of the present
`invention.
`
`The planar coils 25 and 26 are electrically connected in series by one current line.
`Specifically, as illustrated in FIG. 6, a first-layer current line 25a constituting the planar
`coil 25 is wound in a counterclockwise spiral shape from outward to inward when
`viewed from above. As illustrated in FIG. 6 and FIG. 7, an outward end portion of the
`first-layer current line 25a of the planar coil 25 is connected to the mounting terminal
`27a exposed at a surface of a lower face of the yoke-integrated coil portion 24 via a
`connecting line 25b extending in a thickness direction.”
`Miyazaki at [0019]-[0020]
`
`“First, a drive current is supplied to the current lines constituting the planar coils 25 and
`26 via the mounting terminals 27a and 27b. This causes currents in directions (arrow Y1
`and Y2 directions) orthogonal to a magnetic field in the vertical direction arising
`between the N-pole face 311a and the S-pole face 312a of the movable portion 3 to flow
`through the planar coil 25 and the planar coil 26. At this time, an orientation of a current
`flowing through a portion on the arrow X1 direction side in a plan view (“rightward
`portion” hereinbelow) relative to a central portion of the planar coil 25 and the planar
`coil 26 (spiral center portion) and an orientation of a current flowing through a portion
`on the arrow X2 direction side (“leftward portion” hereinbelow) relative to the central
`portion are opposite. Moreover, due to the magnetic field created by the permanent
`magnet 31, a Lorentz force acts in the arrow X1 direction on the rightward portion of the
`planar coils 25 and 26 wherethrough the current flows, and a reaction force thereof acts
`in an arrow X2 direction on the N-pole face 311a of the first magnet 311. At the same
`time, a Lorentz force acts in the arrow X1 direction on the leftward portion of the planar
`coils 25 and 26, and a reaction force thereof acts in the arrow X2 direction on the S-pole
`face 312a of the second magnet 312. From the above, the movable portion 3 undergoes

`
`“As illustrated in FIG. 8, the movable portion 3 is made of the permanent magnet 31,
`which has a tabular shape; a weight 32 made of a material having a large specific gravity
`(for example, tungsten); and a magnet cover 33 of a nonmagnetic material (for example,
`phosphor bronze) covering the permanent magnet 31 and the weight 32. Note that the
`movable portion 3 includes no yoke (magnetic body). The permanent magnet 31 is a
`permanent magnet made of a ferromagnetic material such as ferrite or neodymium. The
`permanent magnet 31 is formed in a substantially rectangular shape in a plan view. The
`weight 32 is formed in a frame shape whose outer shape is substantially rectangular in a
`plan view. Moreover, it has an opening portion 32a of substantially the same shape as the
`permanent magnet 31. The permanent magnet 31 is fitted in the opening portion 32a of
`the weight 32. The permanent magnet 31 and the weight 32 have substantially equal
`thicknesses. The magnet cover 33 is integrally fixed to the permanent magnet 31 and the
`weight 32 so as to cover an entirety of an upper face of the permanent magnet 31 and the
`weight 32, an entirety of a lateral face in the X direction of the weight 32, and one
`portion of a lower face of the weight 32. A lower face of the magnet cover 33 is
`positioned below a lower face of the permanent magnet 31 and the weight 32. Moreover,
`the Nimuflon treatment is applied to an entirety of a surface of the magnet cover 33.
`
`As illustrated in FIG. 4 and FIG. 8, the permanent magnet 31 is constituted by two
`permanent magnets: the first magnet 311 and the second magnet 312. These are
`magnetized to have a pair of magnetic poles in the thickness direction (Z direction).
`Specifically, a configuration is such that the first magnet 311 is disposed on an arrow X1
`direction side and the second magnet 312 is disposed on an arrow X2 direction side, a
`centerline of the movable portion 3 being the boundary. Moreover, in the first magnet
`311, a side opposing the yoke-integrated coil portion 24 is an N-pole face 311a
`magnetized as an N pole, and an opposite side thereof is an S-pole face 311b magnetized

`
`as an S pole. Moreover, in the second magnet 312, a side opposing the yoke-integrated
`coil portion 24 is an S-pole face 312a magnetized as an S pole, and an opposite side
`thereof is an N-pole face 312b magnetized as an N pole.`
`
`Furthermore, the first magnet 311 and the second magnet 312 are disposed so the N-pole
`face 311a and the S-pole face 312a are adjacent at a surface on a yoke-integrated-coil-
`portion 24 side and the S-pole face 311b and the N-pole face 312b are adjacent at a
`surface on an opposite side of the yoke-integrated-coil-portion 24 side. Moreover, the
`first magnet 311 and the second magnet 312 are each held in a state of close contact by
`an attractive force between the mutually adjacent N-pole face 311a and S-pole face 312a
`and an attractive force between the S-pole face 311b and the N-pole face 312b.
`Moreover, they are fixed to each other by an adhesive or the like.
`
`From the above, as illustrated in FIG. 4 and FIG. 5, the movable portion 3 is disposed so
`the magnetic-pole faces of the permanent magnet 31 are parallel to and oppose the yoke-
`integrated coil portion 24. Moreover, in a state of being supported by the spring member
`4, the movable portion 3 moves linearly inside the case 23 in arrow X1 and X2
`directions, which are parallel to the yoke-integrated coil portion 24. Here, “parallel”
`includes not only a mutually parallel state but also a state of being shifted from the
`parallel state by an extent that does not impede the linear movement of the movable
`portion 3 (state of being inclined by a predetermined angle). Moreover, at this time, a
`lateral face in the Y direction of the case 23 has a function as a guide for the movable
`portion 3 moving in the arrow X1 and X2 directions.”

`magnet 31, a Lorentz force acts in the arrow X1 direction on the rightward portion of the
`planar coils 25 and 26 wherethrough the current flows, and a reaction force thereof acts
`in an arrow X2 direction on the N-pole face 311a of the first magnet 311. At the same
`time, a Lorentz force acts in the arrow X1 direction on the leftward portion of the planar
`coils 25 and 26, and a reaction force thereof acts in the arrow X2 direction on the S-pole
`face 312a of the second magnet 312. From the above, the movable portion 3 undergoes
`linear movement in the arrow X2 direction.
`
`Then, by supplying a drive current in an opposite direction after a predetermined time,
`the movable portion 3 undergoes linear movement in the arrow X1 direction by an action
`similar to the above. In this manner, by switching the direction of the drive current at a
`predetermined frequency, the movable portion 3 undergoes reciprocating motion by
`alternating linear movement in the arrow X1 direction and the arrow X2 direction. At
`this time, a magnetic flux arising between the N-pole face 311a of the first magnet 311
`and the S-pole face 312a of the second magnet 312 is absorbed by the yoke 28 and the
`baseplate 21 and selectively passes through the yoke 28 and the baseplate 21. As such, a
`magnetic flux that reaches to outside the case 23 hardly arises. Moreover, a major
`magnetic flux arising between the S-pole face 311b of the first magnet 311 and the N-
`pole face 312b of the second magnet 312 is absorbed by the upper case portion 22 and
`selectively passes through the upper case portion 22. As such, a magnetic flux that
`reaches to outside the case 23 hardly arises.”

`
`“The vibrating motor 1 according to the first embodiment of the present invention is a
`device that is built into a mobile device (not illustrated) or the like and is for imparting
`vibrations to this mobile device. As illustrated in FIG. 1, the vibrating motor 1 is made of
`a fixed portion 2, a movable portion 3 that vibrates relative to the fixed portion 2, and a
`spring member 4 that supports the movable portion 3 so as to enable vibration.
`As illustrated in FIG. 2 and FIG. 3, the fixed portion 2 includes a metal box-shaped case
`23, made of a baseplate (lower case portion) 21 and an upper case portion 22, and a
`yoke-integrated coil portion 24 fixed to the baseplate 21. The baseplate 21 and the upper
`case portion 22 are made of a metal material having magnetism (for example, SPCC).”

`
`“Due to being constituted from a magnetic material, the case 23 (baseplate 21 and upper
`case portion 22) has a function as a magnetic shield (yoke) for suppressing magnetism
`from leaking outside from the case 23. As illustrated in FIG. 2 to FIG. 4, an opening
`portion 21d is formed in a lower face of the baseplate 21, and the yoke-integrated coil
`portion 24 is disposed so as to be fitted in this opening portion 21d. The baseplate 21 and
`the yoke-integrated coil portion 24 are fixed by being adhered at adhesion portions in
`two locations. Specifically, a lower face of a portion 21e (see FIG. 2 and FIG. 3)
`protruding inward, by being bent, from the lateral face 21b of the baseplate 21 in a region
`corresponding to the opening portion 21d and both end portions in the Y direction of an
`upper face of the yoke-integrated coil portion 24 are adhered linearly. Note that the
`baseplate 21 and the upper case portion 22 are respectively one example of the “lower-
`face-side yoke” and the “upper-face-side yoke” of the present invention.”

`
`“From the above, as illustrated in FIG. 4 and FIG. 5, the movable portion 3 is disposed
`so the magnetic-pole faces of the permanent magnet 31 are parallel to and oppose the
`yoke-integrated coil portion 24. Moreover, in a state of being supported by the spring
`member 4, the movable portion 3 moves linearly inside the case 23 in arrow X1 and X2
`directions, which are parallel to the yoke-integrated coil portion 24. Here, “parallel”
`includes not only a mutually parallel state but also a state of being shifted from the
`parallel state by an extent that does not impede the linear movement of the movable
`portion 3 (state of being inclined by a predetermined angle). Moreover, at this time, a
`lateral face in the Y direction of the case 23 has a function as a guide for the movable
`portion 3 moving in the arrow X1 and X2 directions.
`
`As illustrated in FIG. 5 and FIG. 8, the spring member 4 is made of a plate portion 41
`and a pair of spring portions 42 and 43 provided on both sides of the plate portion 41.
`The plate portion 41 and the spring portions 42 and 43 are made of a plate-shaped
`nonmagnetic material (for example, SUS304). A lower face of the plate portion 41 and
`an upper face of the magnet cover 33 are fixed by being adhered. A rectangular opening
`portion 41a is formed in a central portion of the plate portion 41. The opening portion
`41a and the permanent magnet 31 are configured to be substantially the same size in a
`plan view. The SUS304 constituting the plate portion 41 is fundamentally nonmagnetic

`
`but may become magnetized during processing. As such, a magnetic line of force of the
`permanent magnet 31 may become shielded by the plate portion. Here, providing this
`opening portion 41a suppresses the magnetic line of force from the permanent magnet 31
`from becoming shielded by the spring member 4. This causes an entirety or a portion of
`an attractive force (downward attractive force) between, on one hand, the yoke 28 of the
`yoke-integrated coil portion 24 and the baseplate 21 and, on the other, the permanent
`magnet 31 to be offset by an attractive force (upward attractive force) between the upper
`case portion 22 and the permanent magnet 31. Note that the plate portion 41 is one
`example of the “installation portion” of the present invention.”

`
`“More specifically, the spring portion 42 includes a first portion 42a, which is formed
`integrally with the plate portion 41, and a second portion 42b, which is welded to the first
`portion 42a and the upper case portion 22. The first portion 42a and the second portion
`42b are leaf springs. The first portion 42a is in surface abutment with the lateral face of
`the magnet cover 33 at an end portion in an arrow Y1 direction, and an end portion in an
`arrow Y2 direction curves away from the lateral face of the magnet cover 33. The second
`portion 42b is in surface abutment with a lateral face in an arrow X1 direction of the
`upper case portion 22 at an end portion in the arrow Y1 direction, and an end portion in
`the arrow Y2 direction curves away from the lateral face in the arrow X1 direction of the
`upper case portion 22. The end portion in the arrow Y2 direction of the first portion 42a
`and the end portion in the arrow Y2 direction of the second portion 42b are welded in a
`state of making surface contact. Moreover, the spring portion 43 has a configuration
`similar to the spring portion 42 and includes a first portion 43a and a second portion 43b
`having structures similar to the first portion 42a and the second portion 42b. The above
`configuration configures the spring portions 42 and 43 to bias the movable portion 3 in
`mutually opposing directions.”

`“(1) By configuring a vibrating motor 1 that vibrates horizontally (vibrates in the arrow
`X1 and X2 directions), making the vibrating motor thinner is easier compared to a
`vibrating motor that vibrates vertically (vibrates in the vertical direction (Z direction)).

`
`(2) A movable portion 3 is provided that can move along a direction along a surface of
`the planar coils 25 and 26 (arrow X1 and X2 directions). As such, compared to a
`situation of moving the movable portion 3 linearly in the vertical direction using a coil
`having a large thickness in the vertical direction (Z direction), there is no need to provide
`a movement range (movement space in the vertical direction) for the movable portion 3.
`This can ensure freedom in design to decrease a thickness in this direction. As a result, a
`vibrating motor 1 that can be made thinner can be provided.
`
`(3) The planar coils 25 and 26 have a spiral shape so as to be flat along the movement
`direction of the movable portion 3. As such, compared to a situation wherein a winding
`face of the coils is disposed in a direction orthogonal to the movement direction of the
`movable portion, there is no need to provide a region in a height direction due
