In order to specifically describe the content of the present invention, the following examples will be given in detail.

FIG. 1 is a handheld electronic device according to an embodiment of the present invention. FIG. 2 is an exploded view of the handheld electronic device of FIG. 1 . Please refer to FIG. 1 and FIG. 2 at the same time. The handheld electronic device 100 includes a body 110 , a touch display panel 120 and a piezoelectric element 130 . The touch display panel 120 is movably disposed on the machine body 110 , and the touch display panel 120 has a display plane 122 . The piezoelectric element 130 is sheet-shaped, disposed on one side of the touch display panel 120, and disposed between the body 110 and the touch display panel 120, wherein the piezoelectric element 130 is suitable for driving the touch display panel 120 after being energized, The touch display panel 120 generates a first displacement P1 parallel to the display plane 122 and a second displacement P2 perpendicular to the display plane 122 at the same time relative to the body 110 . In this embodiment, the touch display panel 120 can simultaneously generate a biaxial displacement relative to the body 110 , so that the user can feel a three-dimensional tactile feedback.

The body 110 of the handheld electronic device 100 further includes a front frame 114 , a body 115 and a back cover 116 . The front frame 114 has an opening 114a, and the touch display panel 120 is disposed at the opening 114a. The piezoelectric element 130 is disposed between the front frame 114 and the touch display panel 120 .

A plurality of hanging ears 123 are disposed on the periphery of the touch display panel 120 . In this embodiment, two hanging ears 123 are respectively arranged at two ends of the touch display panel 120 as an example. Each hanging ear 123 defines a through hole 123a, and the front frame 114 defines a plurality of guide posts 113 corresponding to each through hole 123a. The touch display panel 120 is sleeved on the corresponding guide post 113 through the through hole 123 a on each hanging ear 123 , and the diameter of the through hole 123 a is larger than the outer diameter of the guide post 113 . In other words, there is a certain gap between the diameter of the through hole 123 a and the outer diameter of the guide post 113 , so that when the piezoelectric element 130 is energized to drive the touch display panel 120 , there is a certain space for the touch display panel 120 to be relative to the body 110 . produce displacement. In more detail, the guide posts 113 corresponding to the through holes 123 a are disposed on the front frame 114 . The touch display panel 120 is sleeved on the corresponding guide post 113 through the through holes 123 a on the mounting ears 123 , and the touch display panel 120 is locked on the front frame 114 by screws 123 b. Since there is a certain gap between the guide post 113 and the through hole 123a, the touch display panel 120 can generate a first displacement P1 parallel to the display plane 122 and a second displacement P2 perpendicular to the display plane 122, and the displacements in the two directions can be generated simultaneously. , so there will be three-dimensional tactile feedback.

FIG. 3A and FIG. 3B respectively illustrate the partial structure of the handheld electronic device of this embodiment, which are used to express the operation mode of the piezoelectric element. 3A is a schematic diagram before the piezoelectric element is energized, and FIG. 3B is a schematic diagram of the relative displacement of the touch display panel relative to the body after the piezoelectric element is energized. 4A and 4B are respectively a front view and a side view of the partial structure of FIG. 3A . 5A and 5B are respectively a front view and a side view of the partial structure of FIG. 3B .

Please refer to FIGS. 1 to 5 at the same time. In order to make the touch display panel 120 have biaxial displacement at the same time, a slope 112 is provided on one side of the body 110 to support the touch display panel 120. The slope 112 is clamped with the display plane 122. An acute angle θ, and the piezoelectric element 130 is suitable for driving the touch display panel 120 to move a displacement P along the slope 112 after being energized. The displacement P can be decomposed into a displacement component along the display plane (ie, the first displacement P1 ) and a displacement component perpendicular to the display plane (ie, the second displacement P2 ). The acute angle θ between the slope 112 and the display plane 122 will affect the magnitude of the first displacement P1 and the second displacement P2 . Therefore, the magnitude of the acute angle θ can be changed according to the displacement component required by the touch display panel 120 . For example, if the acute angle θ of this embodiment becomes larger, the first displacement P1 of the displacement P generated by the touch display panel 120 in the direction parallel to the display plane 122 will decrease, while the second displacement P2 in the direction perpendicular to the display plane 122 will decrease. will increase.

As shown in FIG. 3 , one side of the touch display panel 120 has a first clamping portion C1 and a second clamping portion C2 , such as two C-shaped clamps, respectively clamping two ends of the piezoelectric element 130 . The front frame 114 of the machine body 110 has a third clamping portion C3 clamping the center of the piezoelectric element 130 . The piezoelectric element 130 bends after being energized to drive the third clamping portion C3 to move relative to the first clamping portion C1 and the second clamping portion C2 , so that the touch display panel 120 produces a biaxial displacement. The three-point clamping method in this embodiment is an example for illustration.

In fact, in other embodiments of the present application, the piezoelectric element 130 may have different clamping methods. For example, similar to the above-mentioned three-point clamping method can also be adopted, but the setting method of the clamping part is changed. Specifically, the touch display panel 120 clamps the center of the piezoelectric element 130 via one clamping portion, and two clamping portions are provided on the front frame 114 of the body 110 to clamp both ends of the piezoelectric element 130 . In such a configuration, the piezoelectric element 130 will also bend after being energized to drive the touch display panel 120 to move relative to the front frame 114 of the body 110 to produce the aforementioned biaxial displacement effect.
