[0075] Referring now to FIGS. 22 to 24, an exemplary linear resonance actuator 100 incorporates a shape memory alloy spring 106, that is heated by a heater 104 to change the stiffness of the spring and therefore change the amplitude and/or frequency of vibration. A voice coil 109 creates a magnetic field that creates a force on the magnet 108, such as a permanent magnet. The voice coil may receive an electrical signal having a frequency and the attraction and repulsion magnetic force created on the magnet may follow this frequency and/or amplitude of the magnetic field created. The magnet is coupled with the actuator mass 107 and the control signal sent to the voice coil moves the mass according to the frequency and amplitude of the magnetic field. The actuator mass is actuated back and forth by the changing magnetic field and the shape memory alloy spring is configured between the actuator mass and the end plate 111′ to translate the motion to the end plate. A change in the stiffness of the spring will change the frequency and/or amplitude of motion of the end plate. A heater 104 is controlled by the heater controller 101 and may be used to adjust the temperature of the shape memory alloy spring and therefore the stiffness. A barrier sleeve 105 extends around the heater and a thermal insulation layer 103 is configured between the barrier sleeve 105 and a actuator cover 102. The voice coil controller 110 controls the voice coil to change the frequency and magnitude of the magnetic field.
[0076] It is to understood that one or more shape memory alloy springs may be utilized in a vibrating device, such as an LRA, and may be configured in series or parallel and may have different sizes, spring constants, and may be made out of different alloys and thereby have different changes in stiffness as a function of temperature. For example, a series arrangement of shape memory alloys springs may be used wherein a first spring becomes stiffer at a first transition temperature but the second spring does not change at a first transition temperature and at a second, higher transition temperature, both the first and second shape memory alloy springs have a different stiffness from ambient conditions. This arrangement of two or more springs, which may be shape memory alloy springs or conventional springs may enable a smoother transition from one frequency or amplitude to another.
[0077] A linear resonance actuator may be coupled with a controller 41 that has separate user input features for frequency and amplitude. As shown, the user input feature 42 on the controller 41 has an amplitude input feature 242 that has an amplitude up 248 and an amplitude down 249 control button and a frequency input feature 142 that has a frequency up 148 and a frequency down 149 control button. The frequency and amplitude may be decoupled by the change in spring stiffness, or spring constant, as a function of changing the temperature of the shape memory alloy spring.
[0078] FIG. 25 is a graph of amplitude versus frequency produced by an exemplary vibrating motor.
[0079] FIG. 26 is a graph of response or amplitude versus frequency. An LRA may preferably operate at a frequency that is a resonance frequency of the spring and with a shape memory alloy this resonance frequency can be changed by heating. The small, medium and heavy dampening response lines may be as a result of heating a shape memory alloy spring in an LRA.
[0080] It will be apparent to those skilled in the art that various modifications, combinations and variations can be made in the present invention without departing from the spirit or scope of the invention. Specific embodiments, features and elements described herein may be modified, and/or combined in any suitable manner. Thus, it is intended that the present invention cover the modifications, combinations and variations of this invention provided they come within the scope of the appended claims and their equivalents.
