The touch screen 20 , the circuit board 30 and the vibrating mechanism 60 are respectively electrically connected to the controller 40 . In this embodiment, the electronic device 100 is a touch-sensitive vehicle controller. When the user inputs a command to the electronic device 100 by touching the touch screen 20, the controller 40 controls the vibration mechanism 60 to vibrate, and the vibration mechanism 60 transmits the vibration to the user through the touch screen 20 so that the user receives tactile feedback.

The casing 10 constitutes the main body of the electronic device 100 and is used to accommodate internal components (not shown) of the electronic device 100 . Housing 10 includes an opening 102 . The touch screen 20 is substantially in the shape of a rectangular plate, and its cover is disposed on the opening 102 of the casing 10 to form a closed receiving cavity 202 with the casing 10 . A touch control key (not shown) is provided on the side of the touch screen 20 facing away from the receiving cavity 202 , and the touch control key is used to receive a user's touch command.

The circuit board 30 is substantially rectangular plate-shaped, is accommodated in the receiving cavity 202 , is fixed on the bottom of the casing 10 and faces the touch screen 20 . The circuit board 30 is provided with a threaded hole 301 , and a limiting slot 303 is formed adjacent to the threaded hole 301 . The threaded holes 301 are used to be screwed with fasteners such as screws to fix part of the structure of the vibrating mechanism 60 . The limiting groove 303 is generally a long and narrow rectangular groove, which is used to engage with some structures in the vibrating mechanism 60 to limit it. In this embodiment, there are two limiting grooves 303, and the two limiting grooves 303 are arranged parallel to each other.

The controller 40 is disposed on the circuit board 30 , and is electrically connected to the touch screen 20 , the circuit board 30 and the vibration mechanism 60 to receive a user's touch command and control the vibration mechanism 60 to perform a corresponding feedback action. When the touch screen 20 senses a command input by the user, the command is transmitted to the controller 40, and the controller 40 controls the vibration mechanism 60 to vibrate, so that the vibration is fed back to the user through the touch screen.

Please also refer to FIG. 4 , the vibrating mechanism 60 includes an elastic member 62 and a vibrating member 64 fixed on the elastic member 62 .

The elastic member 62 is roughly in the shape of an irregularly bent sheet, and has elasticity as a whole. The elastic member 62 is disposed between the touch screen 20 and the circuit board 30 , with one side against the circuit board 30 and the other side against the touch screen 20 . In the assembled state, the elastic member 62 is compressed. The elastic member 62 includes a base piece 621 , an elastic arm 623 formed at one end of the base piece 621 , and a top piece 625 formed at an end of the elastic arm 623 away from the base piece 621 .

The substrate 621 is roughly in the shape of a “bow” bent sheet, and is fixedly disposed on the circuit board 30 adjacent to the threaded hole 301 . The substrate 621 includes a fixing part 6211 , a supporting part 6213 , a carrying part 6215 , a connecting part 6217 and a positioning part 6218 which are sequentially connected. The fixing portion 6211 is substantially in the shape of a rectangular sheet, which is stacked on the circuit board 30 . One end of the fixing part 6211 is opened with a mounting hole 6212 for passing fasteners such as screws and threaded into the threaded hole 301 of the circuit board 30 , thereby fixing the fixing part 6211 on the circuit board 30 . The supporting portion 6213 is formed at an end of the fixing portion 6211 away from the mounting hole 6212 , and extends away from the circuit board 30 . The carrying portion 6215 is formed by bending an end of the supporting portion 6213 away from the circuit board 30 , and extends toward a direction away from the fixing portion 6211 , and is substantially parallel to the circuit board 30 . The bearing part 6215 is used for bearing the vibrating element 64 . The connecting portion 6217 is formed by extending an end of the carrying portion 6215 away from the supporting portion 6213 toward the circuit board 30 . The positioning portion 6218 is substantially in the shape of a rectangular sheet, and is formed at an end of the connecting portion 6217 close to the circuit board 30 . The positioning part 6218 and the fixing part 6211 are substantially on the same plane, and they are also stacked on the circuit board 30 . The two sides of the positioning part 6218 are bent corresponding to the two limiting grooves 303 to form two limiting parts 6219, and the two limiting parts 6219 are respectively pierced through the two limiting grooves 303 to position the elastic member 62 on the circuit board 30 on. When the bearing part 6215 is driven to move up and down by an external force, the bearing part 6215 exerts a force on the supporting part 6213 and the connecting part 6217. Since the limiting part 6219 penetrates the two limiting grooves 303, the supporting part 6213 and the connecting part 6217 cannot move along the circuit board 30 , so that the supporting part 6213 and the connecting part 6217 are bent and deformed with the shaking of the bearing part 6215 , so that the shaking range of the bearing part 6215 is enlarged.

The elastic arm 623 is roughly in the shape of a wave-shaped bent sheet, which is formed at an end of the positioning portion 6218 away from the connecting portion 6217 , and extends toward a direction away from the circuit board 30 .

Please also refer to FIG. 5 , the top sheet 625 is formed by bending the end of the elastic arm 623 away from the circuit board 30 , and extends toward one side of the fixing portion 6211 . The top sheet 625 protrudes out of the opening 102 of the casing 10 so that the elastic member 62 is compressed in an assembled state. The top sheet 625 includes a mounting portion 6251 and two clamping portions 6253 and two limiting ends 6255 formed on the mounting portion 6251 . The mounting portion 6251 is approximately in the shape of a rectangular sheet, and is disposed approximately parallel to the circuit board 30 for mounting the vibrating element 64 . The two clamping portions 6253 are respectively formed on two sides of the mounting portion 6251 , and are bent and extended toward the circuit board 30 . The ends of the two clamping parts 6253 that are far away from the installation part 6251 are bent and protrude toward each other to form a clamping end 6254 , and the two clamping ends 6254 are used to cooperate with each other to clamp the vibrating element 64 . The two limiting ends 6255 are respectively adjacent to two ends of the clamping portion 6253 , and protrude from the side of the mounting portion 6251 facing the carrying portion 6215 corresponding to the supporting portion 6213 and the connecting portion 6217 . The two limiting ends 6255 are used to limit the displacement of the vibrating member 64 .

The vibrating element 64 is disposed on a side of the mounting portion 6251 away from the touch screen 20 , and is held between the two clamping portions 6253 and the two limiting ends 6255 , and is supported on the carrying portion 6215 . In this embodiment, the vibration member 64 is a vibration motor. The vibrating element 64 is electrically connected to the controller 40 , and the controller 40 can control the vibrating element 64 to vibrate. Since the elastic member 62 is generally elastic, the vibration generated by the vibrating member 64 is amplified by the elastic member 62 and transmitted to the touch screen 20 , so that the electronic device 100 feels a strong vibration when it vibrates.

When assembling the electronic device 100 of this embodiment, firstly, the circuit board 30 is disposed on the bottom of the casing 10 , and then the controller 40 is mounted on the circuit board 30 and electrically connected to the circuit board 30 . Next, mount the elastic member 62 on the circuit board 30 so that the mounting hole 6212 corresponds to the threaded hole 301, and the two limiting parts 6219 are respectively installed in the two limiting grooves 303, and then use fasteners such as screws The mounting portion 6251 is used to lock the elastic member 62 on the circuit board 30 . Then, apply an external force on the top sheet 625 to keep the installation part 6251 away from the bearing part 6215, then press the vibrating part 64 between the two clamping parts 6253 and the two limit ends 6255, and connect the controller 40 and the vibrating part 64 electrical connection. Finally, the touch screen 20 is electrically connected to the controller 40 and covered on the opening 102 of the casing 10 . The touch screen 20 secures the top sheet 625 of the elastic member 62 , so that the elastic arm 623 of the elastic member 62 is compressed, and the top sheet 625 is close to the bearing portion 6215 , so that the vibrating member 64 is supported on the bearing portion 6215 .

When using the electronic device 100 of this embodiment, first, touch the touch screen 20 to input an instruction, the touch screen 20 transmits the instruction to the controller 40, the controller 40 controls the vibrating element 64 to turn on, and the vibrating element 64 vibrates. Since the vibrating element 64 is fixed on the top plate 625, and one side of it is resisted and supported on the carrying portion 6215, the carrying portion 6215 is suspended on the circuit board 30 through the supporting portion 6213 and the connecting portion 6217, the vibration of the vibrating element 64 The bearing part 6215 is forced to shake up and down, the supporting part 6213 and the connecting part 6217 are bent and deformed with the shaking of the bearing part 6215, the shaking amplitude of the bearing part 6215 is amplified, and the amplified vibration will in turn drive the vibrator 64 to generate greater vibration . At the same time, the vibration generated by the vibrating member 64 also forces the top sheet 625 to vibrate, and the elastic arm 623 undergoes elastic deformation, making the vibration amplitude of the top sheet 625 larger, thereby driving the touch screen 20 to vibrate. Therefore, after the vibration with a small amplitude generated by the vibrating member 64 is double-amplified, the vibration is relatively stronger and transmitted to the user through the touch screen 20, so that the electronic device feels a strong vibration. In summary, in the vibrating mechanism 60 of the electronic device 100 of the present invention, the weak vibration generated by the vibrating member 64 can be amplified by the elastic member 62 into a strong vibration and transmitted to the user without increasing the power input. The vibration amplitude of the vibrating member 64 saves the electric energy of the electronic device 100 .

It can be understood that the electronic device 100 of the present invention is not limited to the touch vehicle controller, and the electronic device 100 can be a portable electronic device, such as a mobile phone and a tablet computer with touch feedback.

In addition, those skilled in the art can also make other changes within the spirit of the present invention. Of course, these changes made according to the spirit of the present invention should be included in the scope of protection claimed by the present invention.
