Pressing Feedback Apparatus and Method, and Electronic Device

A pressing feedback method applied to a pressing feedback apparatus, wherein the pressing feedback apparatus comprises:

• a support member, wherein two ends of the support member are configured to be fixed to a periphery of an assembly hole of a middle frame of an electronic device, wherein the middle frame defines an accommodating cavity in communication with the assembly hole;
• a pressing member arranged on a side of the support member facing away from the accommodating cavity;
• a magnetic component located in the accommodating cavity, wherein the magnetic component comprises a first magnetic body and a second magnetic body, wherein the first magnetic body is arranged on a side of the support member facing away from the pressing member, wherein the second magnetic body is arranged on a side of the first magnetic body facing away from the support member and opposite to the first magnetic body, and wherein the second magnetic body is fixedly arranged relative to the middle frame;
• a pressure detection module arranged on the support member, wherein the pressure detection module is configured to generate an electrical signal corresponding to deformation of the support member;
• and
• a control module electrically connected to the pressure detection module and electrically connected to at least one of the first magnetic body or the second magnetic body, wherein the control module is configured to adjust a drive current of the first magnetic body or the second magnetic body based on the electrical signal to adjust an acting force generated between the first magnetic body and the second magnetic body,
• wherein the method comprises:
• generating, by the pressure detection module in response to detection of deformation of the support member caused when a user presses the pressing member, an electrical signal corresponding to the deformation of the support member;
• sending the electrical signal to the control module;
• and
• adjusting, by the control module, a drive current of the first magnetic body or the second magnetic body based on the electrical signal to adjust the acting force generated between the first magnetic body and the second magnetic body.

An electronic device, comprising:

• a middle frame, wherein the middle frame defines an accommodating cavity, and wherein the middle frame is provided with an assembly hole in communication with the accommodating cavity;
• a display screen and a rear housing arranged on two opposite sides of the middle frame;
• and
• a pressing feedback apparatus, wherein the pressing feedback apparatus comprises:
• a support member, wherein two ends of the support member are configured to be fixed to a periphery of the assembly hole;
• a pressing member arranged on a side of the support member facing away from the accommodating cavity;
• a magnetic component located in the accommodating cavity, wherein the magnetic component comprises a first magnetic body and a second magnetic body, wherein the first magnetic body is arranged on a side of the support member facing away from the pressing member, wherein the second magnetic body is arranged on a side of the first magnetic body facing away from the support member and opposite to the first magnetic body, and wherein the second magnetic body is fixedly arranged relative to the middle frame;
• a pressure detection module arranged on the support member, wherein the pressure detection module is configured to generate an electrical signal corresponding to deformation of the support member;
• and
• a control module electrically connected to the pressure detection module and electrically connected to at least one of the first magnetic body or the second magnetic body, wherein the control module is configured to adjust a drive current of the first magnetic body or the second magnetic body based on the electrical signal to adjust an acting force generated between the first magnetic body and the second magnetic body.
