[0047] The following will disclose multiple embodiments of the present disclosure with the accompanying drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present disclosure. In other words, in some embodiments of the present disclosure, these practical details are not necessary. In addition, in order to simplify the drawings, some conventional structures and elements will be depicted in a simple schematic manner in the drawings.

[0048] Please refer to Figure 1 , which is a schematic diagram illustrating a touch device 100 according to an embodiment of the present disclosure. Figure 1 As shown, in this embodiment, the touch device 100 includes a host 110, a display 120, and a touchpad module. The touchpad module is disposed in a receiving groove 111a of a housing 111 (commonly known as a C / D component) of the host 110. The touch device 100 is taken as an example of a notebook computer, but the present disclosure is not limited to this. In practical applications, the touch device 100 may also be other electronic products that use a touchpad as an input or operating interface (for example: a personal digital assistant, a keyboard including a touchpad, etc.). In other words, the concept of the touch device 100 disclosed in the present disclosure can be applied to any electronic product that uses a touchpad as an input or operating interface. The structure, function, and connection and actuation relationship between some components included in the touch device 100 will be described in detail below.

[0049] Please refer to Figure 2 , which is Figure 1 A partial cross-sectional view of the touch device 100 along the cutting line 2-2. Figure 2 As shown, in this embodiment, the touch device 100 further includes a cover plate 130, a circuit board assembly 140 and a magnet group 160. The cover plate 130, the circuit board assembly 140 and the magnet group 160 are arranged in the receiving groove 111a of the housing 111. The cover plate 130 is exposed from the entrance of the receiving groove 111a. The circuit board assembly 140 is arranged below the cover plate 130 and connected to the cover plate 130 via the adhesive layer 150. The circuit board assembly 140 is also carried on the bottom of the receiving groove 111a and connected to the housing 111 via the connector 180. The circuit board assembly 140 includes a first plate body 141, a second plate body 142 and a plurality of support units 143. A touch electrode layer 141a is arranged on the first plate body 141. A coil group 142a is arranged on the second plate body 142. The support unit 143 is supported between the first plate body 141 and the second plate body 142. The magnet group 160 is disposed on the first plate 141 and is disposed corresponding to the coil group 142 a.

[0050] As can be seen from the above structural configuration, a plurality of support units 143 are disposed inside the circuit board assembly 140 (i.e., between the first plate body 141 and the second plate body 142), thereby enhancing the overall support of the circuit board assembly 140. In addition, the magnet group 160 disposed on the first plate body 141 of the circuit board assembly 140 can further enhance the overall rigidity of the circuit board assembly 140. Thus, when the touch device 100 of this embodiment is used in a larger size, the problem of central deformation of the cover plate 130 can be effectively solved.

[0051] In some embodiments, the touch electrode layer 141 a is configured to sense a touch operation performed by a user using a finger or other touch tool on the cover 130 , and generate a touch signal accordingly.

[0052] like Figure 2 As shown, in this embodiment, the magnet group 160 is disposed on the side of the first plate 141 facing the second plate 142. The coil group 142a is located on the side of the second plate 142 facing the first plate 141. The magnet group 160 disposed on the first plate 141 and the coil group 142a disposed on the second plate 142 constitute a vibration module. The vibration module is configured to generate appropriate vibration acceleration to satisfy the user experience.

[0053] For details, please refer to Figure 3 , which is a drawing Figure 2 A top view of the coil group 142a and the magnet group 160 in FIG. Figure 3 As shown, in this embodiment, the coil group 142a includes two coil units 142a1 and 142a2. The two coil units 142a1 and 142a2 are electrically connected. Specifically, the two coil units 142a1 and 142a2 are wound in the same manner and are connected in series. The coil unit 142a1 includes two straight beam segments 142a11 and 142a12. The straight beam segments 142a11 and 142a12 are arranged side by side up and down. The coil unit 142a2 includes two straight beam segments 142a21 and 142a22. The straight beam segments 142a21 and 142a22 are arranged side by side up and down. The polarity of the magnet group 160 located below the straight beam segments 142a11 and 142a21 is the N pole. The polarity of the magnet group 160 located below the straight beam segments 142a12 and 142a22 is the S pole. For example, when the current direction in the coil units 142a1 and 142a2 (eg Figure 3 When the direction of the thick arrow in the figure is counterclockwise, according to the left-hand rule (i.e., the palm faces the N pole, the four fingers point to the current direction, and the direction of the thumb is the force direction of the conductor), the force directions of the straight bundle segments 142a11, 142a12, 142a21, and 142a22 are all upward. Conversely, when the current direction in the coil units 142a1 and 142a2 is clockwise, the force directions of the straight bundle segments 142a11, 142a12, 142a21, and 142a22 are all downward.

[0054] From this we can see that Figure 2 The vibration module composed of the magnet group 160 and the coil group 142a can be moved in the form of a horizontal linear motor, but the present disclosure is not limited to this. Figure 4 , which is a partial cross-sectional view of a touch device 200 according to another embodiment of the present disclosure. Figure 4 As shown, this embodiment is compared with Figure 2 The difference between the illustrated embodiment is that the present embodiment provides a modified magnet group 260. Specifically, by changing the magnetic pole orientation of the magnet group 260, the vibration module formed by the magnet group 260 and the coil group 142a can be actuated in the form of a vertical linear motor.

[0055] In some embodiments, the coil assembly 142 a is an embedded coil assembly 142 a layer exposed from the upper surface of the second plate 142 , but the disclosure is not limited thereto.

[0056] In some embodiments, the adhesive layer 150 is a pressure sensitive adhesive (PSA), but the present disclosure is not limited thereto.

[0057] In some implementations, the connector 180 is also a pressure-sensitive adhesive layer, but the present disclosure is not limited thereto.

[0058] In some embodiments, the support unit 143 has the effect of reducing vibration noise and effectively releasing vibration stress in the horizontal direction. In order to achieve the above effects, in some embodiments, the Young's modulus of the support unit 143 can be in the range of 0.55Mpa to 0.8Mpa, but the present disclosure is not limited thereto.

[0059] Please refer to Figure 5 , which is Figure 2 FIG. 1 is a top view of the second plate 142 and the support unit 143. Figure 5 As shown, in this embodiment, the second plate body 142 includes a plurality of elastic arm portions 142b. The support units 143 are respectively arranged on the elastic arm portions 142b. Specifically, the second plate body 142 has a plurality of through grooves 142c. The through grooves 142c penetrate the second plate body 142 and are respectively adjacent to the edges of the elastic arm portions 142b. It can be seen that by respectively arranging the support units 143 on the elastic arm portions 142b of the second plate body 142, the elastic arm portions 142b can provide a better shock absorption or seismic isolation effect.

[0060] In some embodiments, the through slot 142c is U-shaped. In other words, the elastic arm portion 142b and the through slot 142c are located within the outer edge of the second plate 142, so that the second plate 142 can maintain a complete outer edge, thereby achieving good control of the deformation of the second plate 142 except the elastic arm portion 142b.

[0061] like Figure 2As shown, in this embodiment, the touch device 100 further includes a plurality of force sensors 170. The force sensors 170 are disposed on a side of the second plate 142 facing the first plate 141. The force sensors 170 disposed on the second plate 142 are configured to generate force sensing signals in response to deformation of the circuit board assembly 140 (e.g., due to a user pressing the cover 130). In actual applications, when the force sensors 170 generate force sensing signals, the circuit board assembly 140 can control the vibration module to generate different vibration forces according to the force sensing signals to provide a tactile feedback effect.

[0062] In some implementations, the force sensor 170 is a strain gauge, but the disclosure is not limited thereto.

[0063] like Figure 2 and Figure 5 As shown, in this embodiment, the force sensors 170 are respectively disposed on the elastic arm portions 142b. Since the elastic arm portions 142b are more easily deformed, the force sensors 170 disposed on the elastic arm portions 142b can effectively increase the sensing sensitivity.

[0064] like Figure 2 As shown, in this embodiment, the connector 180 connected between the housing 111 and the second board 142 has a plurality of recesses 181. Furthermore, the recesses 181 are correspondingly disposed below the force sensor 170. By providing a clearance space below the force sensor 170 through the recesses 181, a space for the circuit board assembly 140 to deform downward (especially a space for the elastic arm portion 142b to deform downward) can be provided.

[0065] like Figure 2 As shown, in this embodiment, the connector 180 has opposite sides. The recess 181 is located on both sides of the connector 180, but the present disclosure is not limited thereto. In practical applications, the recess 181 may be located on only one of the two sides.

[0066] like Figure 2 As shown, in this embodiment, the surface of the housing 111 facing the connector 180 has a plurality of grooves 111b. Furthermore, the grooves 111b are correspondingly disposed below the force sensor 170. The grooves 111b provide a clearance space below the force sensor 170, which can provide space for the circuit board assembly 140 to deform downward (especially for the elastic arm portion 142b to deform downward).

[0067] From the above detailed description of the specific implementation of the present disclosure, it can be clearly seen that in the touch device of the present disclosure, a plurality of support units are arranged inside the circuit board assembly, thereby enhancing the overall support of the circuit board assembly. In addition, the magnet group arranged in the circuit board assembly can further enhance the overall rigidity of the circuit board assembly. Thus, when the touch device of the present disclosure is used in a larger size, the problem of deformation of the center of the cover plate can be effectively solved.

[0068] Although the present disclosure has been disclosed in the above embodiments, it is not intended to limit the present disclosure. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present disclosure. Therefore, the scope of protection of the present disclosure should be determined by the attached claims.
