As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in FIG. 2 and FIG. 3 , it is a perspective view and an exploded view of the first embodiment of the tactile feedback device with an external vibration source of the present invention. The tactile feedback device with an external vibration source of the present invention includes a base plate 20 , a support frame 30 , a plurality of buffer pads 40 , an overlapping plate 50 and a vibration source 60 . The bracket 30 includes a frame 31, a hollow area 32 formed by the frame 31 and at least one cantilever bracket 33, the cantilever bracket 33 is connected to the frame 31 and extends toward the hollow area 32, the cantilever bracket 33 is away from One end connecting the frame 31 is an end area 331, and the base plate 20 is glued by the end area 311; the plurality of buffer pads 40 are fixed between the base plate 20 and the frame 31; the overlapping plate 50 is fixed on the The base plate 20 extends to the outside of the support frame 30 in a cantilever shape; the vibration source 60 is arranged on the overlapping plate 50 and is located outside the support frame 30, so that when the user presses the base plate 20 with fingers, it can The vibration source 60 is driven to reciprocate in a first direction through internal signal induction, and since the bonding plate 50 is combined with the substrate 20 , a good vibration and tactile feedback can be obtained.

Then make a detailed description of each component: the substrate 20 is an electronic device that can provide touch sensing, such as a touch panel, a flat keyboard, a touch screen of a tablet computer, etc. When in contact, a corresponding electronic signal is generated, and the vibration source 60 can be synchronously driven to generate vibration, so that the operation position of the contact point can feel the tactile feedback effect of vibration.

The shape of the support frame 30 is basically a rectangle. For the convenience of subsequent description, the long side direction is defined as the X direction 91, and the short side direction is defined as the Y direction 92. The support frame 30 is mainly responsible for carrying the substrate 20. The support frame 30 includes the frame 31, the hollow area 32 in the middle and at least one cantilever support 33. In this embodiment, in order to obtain uniform vibration feedback, the cantilever support 33 is provided with a pair and the positions are parallel to each other. The pair of cantilever brackets 33 are connected to the frame 31 and are located on opposite sides of the frame. An end of the cantilever bracket 33 away from the frame 31 is the end area 313 , and is bonded to the substrate 21 by the end area 331 . In addition, the cantilever bracket 33 also forms at least one neck section 332 with a narrower width, and there are two neck sections 332 in this embodiment. The neck section 332 can adjust the rigidity of the cantilever bracket 33 so that it does not affect the vibration frequency of the structure during operation. In addition, the support frame 30 further includes a protruding frame 34 located on a partial section of the frame 31 . In this embodiment, the protruding frame 34 is disposed in the Y direction 92 of the frame 31 . The raised frame 34 is U-shaped and the raised direction is far away from the direction of the base plate 20, so that the raised frame 34 forms a channel 341, and the channel 341 is for the overlapping plate 50 to extend to the outside of the support frame 30. Both the lateral width and the longitudinal dimension of the channel 341 are larger than the overlapping plate 50 . In principle, when the substrate 20 is pressed down or the vibration source 60 vibrates, the overlapping plate 50 must not be in contact with the raised frame 34 . Of course, the protruding direction of the protruding frame 34 can also face the direction of the substrate 20 and form the channel 341 to reduce the overall thickness after assembly.

The buffer pad 40 is respectively fixed on the base plate 20 and the frame 31 by the upper and lower end surfaces, as the medium connecting the frame 30 and the base plate 20, the material of the buffer pad 40 must help the base plate 20 and the vibration The source 60 generates a resonant frequency, whereby a large vibration can be generated with a small periodic driving force to obtain good vibration feedback. The buffer pad 40 can be made of silica gel, foam, etc., and is evenly distributed between the frame 31 and the substrate 20 .

The overlapping plate 50 is a flat carrier, which is T-shaped in this embodiment, but it is not limited thereto. Part of the overlapping plate 50 is glued to the bottom surface of the base plate 20 , and extends to the outside of the frame 30 through the channel 341 in a cantilever shape. The larger area of the overlapping plate 50 is located outside the support frame 30, where the vibration source 60 is disposed.

The vibration source 60 is a vibration motor, which drives the base plate 20 through the connecting plate 50. After being powered on, the vibration source 60 can provide reciprocating vibration in the first direction. The cantilever support 33 is arranged along the second direction. The first direction and the second direction are perpendicular to each other. In this embodiment, the first direction refers to the Y direction 92 , and the second direction refers to the X direction 91 . In this way, the vibration direction generated by the vibration source 60, due to the increased rigidity of the cantilever bracket 33, offsets the rotational inertia of the Z axis, and can maintain the resonance effect of the original frequency, and then all operating positions on the substrate 20 A tactile feedback effect with uniform vibration can be obtained.

In the above embodiment, although the vibration source 60 of the present invention is arranged on the outside of the support frame 30 , and in combination with the design of the cantilever bracket 33 , uniform vibration feedback effects can still be obtained at different operating positions. Of course, this structure can also be widely used, so the utility model also provides several different embodiments. As shown in Fig. 4 and Fig. 5, it is a perspective view and an exploded view of the second embodiment of the utility model. This implementation still includes a base plate 20, a support frame 30, a plurality of buffer pads 40, an overlapping plate 50, and a vibration source 60. However, it is located at the X direction 91, so the raised frame 34 is also located at the frame 31 of the X direction 91, and the cantilever bracket 33 is still a pair and extends from the frame 31 to the hollow area 32, but parallel to the Y Direction 92 direction configuration. In addition, in order to make the vibration more even, the vibration direction produced by the vibration source 60 must be perpendicular to the extension direction of the cantilever support 33. In this embodiment, the vibration direction produced by the vibration source 60 is the X direction 91, and the cantilever support 33 is then is parallel to the Y direction 92 .

As shown in FIG. 6 , it is an exploded view of the third embodiment of the present invention. The present embodiment still includes a base plate 20, a support frame 30, a plurality of buffer pads 40, an overlapping plate 50 and a vibration source 60, the difference being that the support frame 30 is only provided with one cantilever support 33 at the frame 31 , but the installation direction of the cantilever bracket 33 is perpendicular to the vibration direction that the vibration source 60 can generate. In this embodiment, the vibration source 60 is set in the Y direction 92 of the frame 31 , and the cantilever bracket 33 is connected to the frame 31 parallel to the X direction 91 .

Based on the above, a tactile feedback device for an external vibration source in the present invention is to set the vibration source 60 on the lap plate 50 and extend it in a cantilever shape outside the support frame 30, so that the vibration source 60 is located The location of the bracket 30 and the base plate 20 can avoid the dense electronic components, so that the configuration of the electronic equipment in the installation space is more flexible and convenient.

The above-mentioned ones are only preferred embodiments of the present invention, and are not intended to limit the scope of the embodiments of the present invention. That is, all equivalent changes and modifications made according to the patent scope of the utility model are covered by the patent scope of the utility model.
