The overlapping plate is fixed 60 on the base plate 20 , and the overlapping plate 20 extends outside the base plate 30 in a cantilever shape. The supporting frame 30 includes a frame 31 , a hollow area 32 formed by the frame 31 , and at least one protruding frame 33 , and the protruding frame 33 is a partial section of the frame 31 . The vibration source 50 includes a magnet set 51 and a coil set 52. The magnet set 51 and the coil set 52 are fixed between the protruding frame 33 and the overlapping plate 60.

The plurality of buffer pads 40 are fixed between the base plate 20 and the frame 31 to maintain a gap between the magnet set 51 and the coil set 52; thus, the vibration source 50 drives the base plate 20 to generate reciprocating vibration during operation , allowing the user to touch the substrate 20 with fingers to obtain a good vibratory tactile feedback. In the present invention, the magnet set 51 and the coil set 52 are respectively disposed on the protruding frame 33 and the overlapping plate 60 and are located outside the base plate 20 , so that the size of the stack where the vibration source 50 is located is smaller than that of the base plate 20 and the buffer. The size of the stacking pad 40 and the support frame 30 is to achieve the purpose of thinning the product.

Next, a detailed description of each component is made: the substrate 20 is an electronic device that can provide touch sensing, such as a touchpad, a flat keyboard, a touch screen of a tablet computer, etc. When in contact, a relative electronic signal is generated, and the vibration source 50 can be driven to vibrate synchronously, so that the operating position of the contact point can feel the tactile feedback effect of the vibration.

The outer shape of the support frame 30 is basically a rectangle. For the convenience of the 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 supporting frame 30 is mainly responsible for carrying the substrate 20 , and the supporting frame 30 includes the frame 31 , the hollow area 32 in the middle, and at least one protruding frame 33 . The protruding frame 33 is located in a partial section of the frame 31. In this embodiment, the protruding frame 33 is disposed in the X direction 91 of the frame 31.
