To describe mobile communication terminal 10 now in detail as electronic installation.
Referring to figs. 1 through Fig. 3, the mobile communication terminal 10 as electronic installation can comprise housing 12 and 14, display panel 22, actuator 60 and oscillating plate 40 according to an exemplary embodiment of the present invention.
Here, as the haptic device 20 of the mechanism of needs vibrations be the inner member of the mobile communication terminal 10 that need react in response to outside contact pressure.
Except the display panel 22 of mobile communication terminal 10, haptic device 20 can also be input media, OA device, automatic vending machine, bed, card, drive unit, ticket etc.
In the mobile communication terminal 10 of conduct, provide the display panel 22 of image to be used as haptic device 20 according to the electronic installation of this exemplary embodiment.That is, when contact pressure changed according to the contact that is applied to display panel 22, display panel 22 was made a response to sense of touch in response to this contact.
In order to make a response, actuator 60 must produce vibration with making display panel 22 senses of touch.Actuator 60 vibrative ultimate principles will be described in the back.
The vibration transfer that oscillating plate 40 can produce actuator 60 is to display panel 22.Actuator 60 can directly invest display panel 22, so that display panel 22 vibrations, but actuator 60 can optionally be used to reduce to vibrate the impact or the amplification vibration of generation as required.
That is to say, can carry out injection moulding by impact lightening material (impact-lessening material) and make oscillating plate 40; Yet the present invention is not intended to be confined to this.In addition, can be according to adjusting the thickness of oscillating plate 40 with the interaction of actuator 60.When experiment showed that thickness when oscillating plate 40 is less than 0.2mm, vibration increased sharply, and therefore can suitably select the thickness of oscillating plate 40 according to the range of needs of vibrating.
To describe tactile feedback actuators 30 and haptic device in detail now.The detailed characteristics of tactile feedback actuators of Miao Shuing and haptic device all can be applied to electronic installation of the present invention hereinafter.
[tactile feedback actuators and haptic feedback devices]
But tactile feedback actuators 30 involving vibrations plates 40 and actuator 60 according to an exemplary embodiment of the present invention.In addition, haptic feedback devices 50 can comprise haptic device 20 and make the tactile feedback actuators 30 of haptic device 20 vibrations that wherein, contact pressure is applied to haptic device 20.
Here, the oscillating plate 40 of haptic feedback devices 50 can be optional.
Described the oscillating plate 40 about mobile communication terminal 10 above in detail, oscillating plate 40 can adhere to along the edge of the profile that constitutes haptic device 20.
That is to say that as shown in Figure 3, oscillating plate 40 can be formed thin bar, and can be along the edge setting of the display panel 22 of rectangular shape.
Here, suppose the long limit of rectangular display panel 22 is defined as longitudinal direction, will be defined as horizontal direction than short limit.
Specifically, oscillating plate 40 can have many branch lines 42 and 44, and described many branch lines 42 and 44 are in the marginal portion of display panel 22 along the longitudinal direction as the display panel 22 of haptic device 20, and slit 43 can be formed between many branch lines 42 and 44. Branch line 42 and 44 can have substantially the same width, can adhere to almost identical with the width of branch line 42 and the 44 bar shaped actuator 60 of width, makes actuator 60 be set on branch line 42 and 44.In this case, actuator 60 can be configured to parallel with 44 with branch line 42.
Described actuator can be configured to piezo-activator or polymer actuator, makes that the variation according to the contact pressure of haptic device 20 is excited, thereby produces vibration.
Simultaneously, the length of actuator 60 and oscillating plate 40 and actuator 60 position that is provided with on haptic device 20 is a key factor of determining the vibratory output of haptic device 20.
To describe the variation of vibratory output now in detail according to the length of actuator 60 and oscillating plate 40.
Fig. 4 a and Fig. 4 b illustrate the actuator with different length of tactile feedback actuators and the side view of oscillating plate according to an exemplary embodiment of the present invention.Fig. 5 a and Fig. 5 b are the amplification views of the part of Fig. 4 b, the operational shape of its schematically illustrated tactile feedback actuators.Fig. 6 demonstrates the curve map of displacement with respect to the vibration frequency of the tactile feedback actuators of Fig. 4 a and Fig. 4 b.
Fig. 4 a shows the exemplary embodiment of the equal in length of the length of oscillating plate 40 and actuator 60, and Fig. 4 b shows oscillating plate 40 exemplary embodiment longer than actuator 60.
Here, use piezo-activator to measure the displacement (μ m) of haptic device 20 according to vibration number as actuator 60.
Shown in Fig. 5 a and Fig. 5 b, piezo-activator 60 is by piling up the ceramic duplexer that ceramic layer 62 and 64 forms on the both sides of the electrode of being made by silver (Ag) or other impurity 63, and ceramic layer 62 is formed along identical direction with 64 polarization (polarization/polling).
Because ceramic layer 62 forms along identical direction with 64 polarization, so compare with the situation that forms polarization in the opposite direction, vibratory output increases, and therefore can suitably select vibratory output according to the range of needs of vibration.
Under ceramic layer 62 and situation that 64 polarization forms along identical direction, when pressure was applied to piezo-activator, actuator 60 was subjected to displacement in a longitudinal direction, and oscillating plate 40 is not subjected to displacement.
Thus, when actuator 60 is subjected to displacement in a longitudinal direction, tactile feedback actuators 30 up-down vibration.
Curve among Fig. 6 (a) and (b) be to demonstrate according to the exemplary embodiment of Fig. 4 a and Fig. 4 b when increasing vibration frequency, the result's who obtains by the vertical displacement amount of measuring haptic device 20 curve map.

With reference to Figure 10, use anaerobic adhesive 25 as the bonding agent that is used for haptic device 20 and oscillating plate 40, use the bonding agent of resinoid 45 as oscillating plate 40 and actuator 60.
Therefore, for as much as possible, transmitting vibrations and do not cause displacement on haptic device 20 suitably, can select anaerobic adhesive 25, this is because anaerobic adhesive 25 is compared more effectively transmitting vibrations with the bonding agent of being made by elastomeric material.
Simultaneously, oscillating plate 40 and actuator 60 need to use resinoid 45, and resinoid 45 can keep vibrating rigidity and have bigger bond strength for transfer of vibration.
Figure 11 is the curve map that is illustrated in the displacement of measuring under the situation of using anaerobic adhesive 25 and resinoid 45 that changes according to vibration number.Should be pointed out that anaerobic adhesive 25 demonstrates the obvious increase of vibratory output according to the increase of vibration frequency, and thermoset resin 45 vibratory outputs increase greatly along with the increase of vibration frequency not, but demonstrate comparatively firm stationarity.
