Embodiment 1

[0042] Embodiment 1: The material of the sensing element 22 is a material having a Hall effect.

[0043] Specifically, the sensing element 22 is made of a material having a Hall effect. Preferably, the outer surface of the inductive element 22 made of a material having a Hall effect does not protrude from the outer surface of the circuit 23 part, such as: the inductive element 22 and the circuit 23 arranged on the same surface of the insulating plate 21 are in a plane, In order to avoid increasing the overall thickness of the sensing operation module.

[0044] Preferably, the sensing element 22 can be made of graphene or semiconductor materials, such as germanium, silicon, gallium arsenide, indium arsenide, indium antimonide, with a thickness of about 20 μm. It has the characteristics of high mobility (mobility>2900cm2 / V·s), high Hall coefficient and good deformation recovery, and thin thickness to improve the overall sensitivity.

Embodiment 2

[0057] Embodiment 2: The material of the inductive element 22 is a material with a giant magnetic effect.

[0058] The specific inductive element 22 is made of materials with giant magnetic effect. Preferably, the outer surface of the inductive element 22 made of a material with a giant magnetic effect does not protrude from the outer surface of the circuit part, such as: the inductive element 22 and the circuit 23 arranged on the same surface of the insulating plate 21 are in a plane, so as to Avoid increasing the overall thickness of the sensing operation module.

[0059] Such as Figure 5 , shows another example of the sensing module, wherein the sensing module 2 includes at least one sensing element 22 with Hall effect. Preferably, when the sensing module 2 includes at least two sensing elements 22, at least two sensing elements 22 are arranged in parallel; or each sensing element 22 is powered by an independent power supply.

[0060] Specifically, the first end of the ...

Abstract

The invention discloses a sensing operation module and a terminal. The sensing operation module includes a magnetic material layer, an insulation plate and a sensing module body, wherein the sensing module body includes one or more sensing elements with the function of sensing the magnetic field variation of the magnetic material layer, and the sensing elements are arranged on the insulation plate. The sensing operation module can quantify pressure, hole forming conducted on a contact plate connected with the magnetic material layer is avoided, therefore, hole forming conducted on the terminalis avoided, the waterproof performance of the terminal can be improved, and the integrity of a whole machine is improved.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to an induction operation module and a terminal. Background technique [0002] Buttons are one of the basic configurations of the terminal, such as volume buttons, power buttons, virtual buttons, etc. The buttons realize the corresponding functions by pressing the button panel, such as: volume increase and decrease functions, screen off function, screen bright function, etc. At present, the button of the terminal generally adopts a tact switch, and its principle is to use a metal shrapnel button to complete the switch between the on-state and the off-state of the switch. When the tact switch is pressed, the shrapnel is deformed by the elastic force and touches the solder piece downward, so that the two sets of pins of the switch are conducted, and the circuit is in a conducting state. When the external force is withdrawn, the shrapnel elastically recovers and separates...
