     BACKGROUND 
     Haptic technology is becoming a more popular way of conveying information to a user. Haptic technology, which may simply be referred to as haptics, is a tactile feedback based technology that stimulates a user&#39;s sense of touch by imparting relative amounts of force to the user. 
     A haptic device or haptic actuator is an example of a device that provides the tactile feedback to the user. In particular, the haptic device or actuator may apply relative amounts of force to a user through actuation of a mass that is part of the haptic device. Through various forms of tactile feedback, for example, generated relatively long and short bursts of force or vibrations, information may be conveyed to the user. 
     SUMMARY 
     A haptic actuator may include a housing, at least one coil carried by the housing, and a field member having opposing first and second sides. The haptic actuator may also include a respective flexure bearing mounting each of the first and second sides of the field member to be reciprocally movable within the housing responsive to the at least one coil. At least one of the flexure bearings may include an arm and a damper body attached thereto. 
     The haptic actuator may also include an adhesive layer between the arm and the damper body. The adhesive layer may include a pressure sensitive adhesive layer, for example. 
     The arm may have a strip shape with opposing major surfaces, and the damper body may have a rectangular shape carried by one of the opposing major surfaces of the arm. 
     The at least one flexure bearing may also include a further arm joined together with the arm at proximal ends thereof and each having spaced apart distal ends operatively coupled between adjacent portions of the field member and the housing. The damper body may be carried by the spaced apart distal end of the arm, for example. 
     The arm and further arm may define a wishbone shape. The at least one flexure bearing may have a bend therein joining together the arm and the further arm at the proximal ends. The damper body may include stainless steel, for example. 
     A method aspect is directed to a method of making a haptic actuator. The method may include mounting a field member having opposing first and second sides within a housing using a respective flexure bearing so that each of first and second sides of the field member is reciprocally movable within the housing responsive to at least one coil. The method may also include attaching a damper body to at least one arm of at least one flexure bearing.

     DETAILED DESCRIPTION 
     The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout, and prime and multiple prime notation is used to refer to like elements in different embodiments. 
     Referring initially to  FIGS. 1 and 2 , an electronic device  20  illustratively includes a device housing  21  and a controller  22  carried by the device housing. The electronic device  20  is illustratively a mobile wireless communications device, for example, a wearable wireless communications device, and includes a band  28  or strap for securing it to a user. The electronic device  20  may be another type of electronic device, for example, a cellular telephone, a tablet computer, a laptop computer, etc. 
     Wireless communications circuitry  25  (e.g. cellular, WLAN Bluetooth, etc.) is also carried within the device housing  21  and coupled to the controller  22 . The wireless communications circuitry  25  cooperates with the controller  22  to perform at least one wireless communications function, for example, for voice and/or data. In some embodiments, the electronic device  20  may not include wireless communications circuitry  25 . 
     A display  23  is also carried by the device housing  21  and is coupled to the controller  22 . The display  23  may be a liquid crystal display (LCD), for example, or may be another type of display, as will be appreciated by those skilled in the art. 
     Finger-operated user input devices  24   a ,  24   b , illustratively in the form of a pushbutton switch and a rotary dial are also carried by the device housing  21  and are coupled to the controller  22 . The pushbutton switch  24   a  and the rotary dial  24   b  cooperate with the controller  22  to perform a device function in response to operation thereof. For example, a device function may include a powering on or off of the electronic device  20 , initiating communication via the wireless communications circuitry  25 , and/or performing a menu function. 
     The electronic device  20  illustratively includes a haptic actuator  40 . The haptic actuator  40  is coupled to the controller  22  and provides haptic feedback to the user in the form of relatively long and short vibrations or “taps”, particularly when the user is wearing the electronic device  20 . The vibrations may be indicative of a message received, and the duration of the vibration may be indicative of the type of message received. Of course, the vibrations may be indicative of or convey other types of information. More particularly, the controller  22  applies a voltage to move a moveable body or masses between first and second positions in a y-axis. 
     While a controller  22  is described, it should be understood that the controller  22  may include one or more of a processor and other circuitry to perform the functions described herein. For example, the controller  22  may include a class-D amplifier to drive the haptic actuator  40  and/or sensors for sensing voltage and current. 
     Referring now additionally to  FIGS. 3-5 , the haptic actuator  40  includes an actuator housing  41 . The actuator housing  41  illustratively has a dimension in a length direction greater than a width direction. The actuator housing  41  may be ferritic. More particularly, the top and bottom of the actuator housing  41  may be ferritic. Of course other and/or additional portions of the actuator housing  41  may be ferritic. 
     The haptic actuator  40  also includes first and second coils  44 ,  45  carried by the actuator housing  41 , for example, the top and the bottom, respectively. The first and second coils  44 ,  45  may have a loop shape or “racetrack” shape and may be aligned in a stacked relation and spaced apart. While first and second coils  44 ,  45  are illustrated, it should be noted that any number of coils may be used, for example, a set of first coils and a set of second coils carried by the top and bottom of the actuator housing  41 , respectively. 
     The haptic actuator  40  also includes a field member  50  carried by the actuator housing  41 . The field member  50 , similarly to the actuator housing  41 , has a dimension in a length direction greater than a width direction. Thus, the field member  50  is reciprocally movable in the width direction (i.e., the y-direction). While the movement of the field member  50  is described as being moveable in one direction, i.e., a linear haptic actuator, it should be understood that in some embodiments, the field member may be movable in other directions, i.e., an angular haptic actuator, or may be a combination of both a linear and an angular haptic actuator. 
     The field member  50  illustratively includes permanent magnets  51 ,  52  between the first and second coils  44 ,  45 . The permanent magnets  51 ,  52  may be neodymium, for example, and may be positioned in opposing directions with respect to their respective poles. 
     The permanent magnets  51 ,  52  may also have a rectangular shape and may be aligned along a length of the first and second coils  44 ,  45 . It will be appreciated that there may be any number of permanent magnets having any shape between the first and second coils  44 ,  45 . 
     The field member  50  also includes a mass  57  between the permanent magnets  51 ,  52 . The mass  57  may be tungsten, for example. The mass  57  may be a different material and there may be more than one mass. For example, masses may be between the permanent magnets  51 ,  52  and may be part of the body of the field member  50 , extending across the field member and defining openings therein. 
     The haptic actuator  40  also includes respective flexure bearings  60   a ,  60   b  mounting each of first and second sides  53 ,  54  of the field member  50  to be reciprocally movable within the actuator housing  41  responsive to the first and second coils  44 ,  45 . While the term flexure bearing is used, it should be understood by those skilled in the art that it may include a flexure spring and flexure suspension, for example. A respective anchor body  47  may be mounted between the corresponding flexure bearing  60   a ,  60   b  and adjacent portions of the actuator housing  41 . 
     Each of the flexure bearings  60   a ,  60   b  includes a flexible member  63  having a wishbone or Y-shape, with two diverging arms  62   a ,  62   b  joined together at proximal ends  75   a ,  75   b . The two diverging arms  62   a ,  62   b  have spaced distal ends  76   a ,  76   b  operatively coupled between adjacent portions of the field member  50  and the actuator housing  41 . Each diverging arm  62   a ,  62   b  has a strip shape with opposing major surfaces  79   a ,  79   b . Each flexure bearing  60   a ,  60   b  may have more than one flexible member  63 . 
     The flexible member  63  has a bend  78  therein joining together the two diverging arms  62   a ,  62   b  at the proximal ends  75   a ,  75   b . The bend  78  causes the two diverging arms  62   a ,  62   b  to be spaced apart at the distal ends  76   a ,  76   b . Illustratively, the two diverging arms  62   a ,  62   b  include a parallel portion  77   a ,  77   b  at the distal ends  76   a ,  76   b . In some embodiments, the distal ends  76   a ,  76   b  of the two diverging arms  62   a ,  62   b  may continue to diverge instead of turning or becoming parallel. In some embodiments, the two diverging arms  62   a ,  62   b  may be parallel at the proximal ends  75   a ,  75   b  and coupled together, for example, via a weld joint. 
     Each flexure bearing  60   a ,  60   b  also illustratively includes a damper body  81 , for example, a stainless steel damper body, attached to one of the two diverging arms  62   a ,  62   b . The damper body  81  may also or alternatively include aluminum. The damper body  81  may be or include other and/or additional materials. 
     The damper body  81  may have a rectangular shape carried by one of the opposing major surfaces  79   a ,  79   b  of the respective diverging arm  62   a ,  62   b . Exemplary dimensions of the damper body  81  are 2.2 mm×1.8 mm×0.15 mm. The damper body  81  is illustratively carried by the spaced apart distal end of the respective diverging arm  62   a ,  62   b  facing the other diverging arm. More particularly, the damper body  81  is carried by the suspended arm  62   a.    
     The damper body  81  is illustratively used in conjunction with a bumper body  83 . Illustratively, the bumper body  83  may be carried by the spaced apart distal end  76   a ,  76   b  of a diverging arm  62   a ,  62   b , and the damper body  81  may be carried by the same diverging arm spaced from the bumper body closer to the proximal end  75   a ,  75   b . In some embodiments, the damper body  81  and the bumper body  83  may combined into a single body of material. More than one damper body  81  may be carried by a given diverging arm  62   a ,  62   b , and/or a damper body  81  may be carried by the other diverging arm. Additionally, placement of the damper body  81  may be based upon a desired Q-factor in different modes of operation of the haptic actuator  40 , for example. 
     An adhesive layer  82  is between the damper body  81  and the respective diverging arm  62   a ,  62   b . The adhesive layer  82  may be a pressure sensitive adhesive, such as, for example, RA960 Damping Adhesive available from Roush Enterprises of Livonia, Mich. 
     Exemplary installation or production techniques of the damper body  81  and adhesive layer  82  will now be described. One example technique is based upon the pick-and-place technique. It may be desirable to place the damper body  81  and the adhesive layer  82  before flexure bending. The flexure bearing  60   a ,  60   b  may undergo heat treatment after flexure bending. The damper body  81  and adhesive layer  82  may also be positioned before laser spot welding, however, this may cause the flexure to be exposed to temperatures greater than 300° F. Alternatively, the damper body  81  and adhesive layer  82  may also be positioned after laser spot welding, however, this particular attention to the bond quality may be desirable. 
     As will be appreciated by those skilled in the art, during operation of the haptic actuator  40 , the flexure bearings  60   a ,  60   b  may continue to move or flex even after the field member  50  has stopped moving, which may generate unwanted noise. For example, yaw-mode coupled z-axis motion may be a cause for ring down noise. Thus, the damper body  81  may provide increased damping of noise generated by the continued movement of the flexure bearings  60   a ,  60   b . For example, the damper body  81  may provide a 1% damping to provide improved acoustics or noise reduction. The damper body  81  may also provide greater than 2% damping effectiveness for yaw-mode and Y-mode operations, and the adhesive layer  82  may be particularly helpful for moving the yaw-mode “higher” so as to separate it from the z-mode. 
     An exemplary damper body  81  and adhesive layer  82  of 150 microns of stainless steel and 50 microns of pressure sensitive adhesive, respectively, for example, may provide upwards of or greater than 1% damping for yaw modes of operation. A 1% modal damping, for example, may make free vibration decay fast enough to eliminate the ring down effect, which may be undesirable with respect to noise. The above exemplary damper body  81  and adhesive layer  82  may also provide greater than 1% damping for Y modes of operation. With respect to temperature, the above exemplary damper body  81  and adhesive layer  82 , through simulation, show that there may be no damping distribution difference between room temperature and high temperature. However a smaller adhesive layer  82 , for example, 25 microns, may improve operation at higher temperatures. 
     The table below shows simulations of how much damping is required.

Illustratively, a damper body  81 ′ is carried by the outer flexible member  63   a ′ only, and corresponding bumper bodies  83   a ′,  83   b ′ are carried by respective spaced apart distal ends  76   a ′,  76   b ′ of each diverging arm  62   a ′,  62   b′.    
     Referring now to the graph  135  in  FIG. 10 , the damping effectiveness versus modulus of the pressure sensitive adhesive layer  82 ′ is shown for a stainless steel damper body  81 ′ of 150 microns carried by the outer flexible member  63   a ′ only ( FIG. 9 ) with a 25 micron pressure sensitive adhesive layer  82 ′ across modes of operation. Line  136  corresponds to the working mode, line  137  corresponds to the Y-mode, line  138  corresponds to the Z-mode, line  139  corresponds to the yaw-mode, and line  140  corresponds to the rocking mode. 
     Referring now to  FIG. 11 , in another embodiment, corresponding damper bodies  81   a ″,  81   b ″ may be carried by the outer arms  62   a ″ of each of the inner and outer flexible members  63   a ″,  63   b ″. The corresponding graph  145  in  FIG. 12 , illustrates the damping effectiveness versus modulus of the pressure sensitive adhesive layer  82 ″ is shown for a stainless steel damper body  81 ″ of 150 microns carried by the outer arms  62   a ″ of both the inner and outer flexible  63   a ″,  63   b ″ ( FIG. 11 ) with a 25 micron pressure sensitive adhesive layer  82 ″ across modes of operation. Line  146  corresponds to the working mode, line  147  corresponds to the Y-mode, line  148  corresponds to the Z-mode, line  149  corresponds to the yaw-mode, and line  150  corresponds to the rocking mode. 
     Referring now to  FIG. 13 , in another embodiment, the damper body  81 ′″ and adhesive layer  82 ′″ form the bumper body  83 ′″ (e.g. combined into a single monolithic unit). The graph  155  in  FIG. 14  illustrates the effectiveness of a combined damper body  81 ′″, adhesive layer  82 ′″, and bumper body  83 ′″. The damper body  81 ′″ portion is a 100 microns thick stainless steel and the pressure sensitive adhesive layer  82 ′″ portion is 25 microns thick. Line  156  corresponds to the working mode, line  157  corresponds to the Y-mode, line  158  corresponds to the first rocking mode, line  159  corresponds to the Z-mode, line  160  corresponds to the yaw-mode, and line  161  corresponds to the second out-of-plane rocking mode. 
     A method aspect is directed to a method of making a haptic actuator  40 . The method includes mounting a field member  50  having opposing first and second sides  53 ,  54  within a housing  41  using a respective flexure bearing  60   a ,  60   b  so that each of first and second sides of the field member is reciprocally movable within the housing responsive to at least one coil  44 ,  45 . The method also includes attaching a damper body  81  to at least one arm  62   a ,  62   b  of at least one flexure bearing  60   a ,  60   b.    
     While an exemplary embodiment of a type and arrangement of flexure bearings has been described herein, it will be appreciated that other types of flexure bearings may be used, for example, which may have a different shape, size, flexure members, and/or anchor members. Moreover, while flexure bearings are described, in some embodiments, flexure bearings may be replaced with or used in conjunction with shafts, biasing members, and mechanical bearings. Still further, while the coils  44 ,  45  have been described as being stationary and the permanent magnets  51 ,  52  being movable, it will be appreciated that the coils may be carried by the field member  50  (i.e., movable) while the permanent magnets are fixed or carried by the actuator housing  41 .
