While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Some concepts and/or terms involved in the schemes provided by the embodiments of the present application are explained below.

Piezoelectric ceramic is electronic ceramic material with piezoelectric property. The crystal phase constituting the main component thereof is a crystal grain having ferroelectricity. Since ceramics are polycrystalline aggregates with randomly oriented grains, the spontaneous polarization vectors of the individual ferroelectric grains therein are also randomly oriented. In order to make the ceramic exhibit macroscopic piezoelectric properties, it is necessary to subject the piezoelectric ceramic to polarization treatment under a strong direct current field after firing and coating the end face with an electrode so that respective polarization vectors of the original disordered orientations are preferentially oriented in the electric field direction. After the electric field is canceled, the piezoelectric ceramic subjected to polarization treatment can keep certain macroscopic residual polarization intensity, so that the ceramic has certain piezoelectric properties.

Referring to fig. 1, fig. 1 is a graph showing the change of electric domains by inverse piezoelectric effect, fig. 1 (a) shows the distribution of electric domains before polarization treatment, the electric domains refer to areas with consistent polarization directions, it can be seen that the polarization directions of adjacent areas in fig. 1 (b) are different in the polarization treatment, a sufficiently high direct current electric field is added to the piezoelectric ceramic, and a certain temperature and time are maintained, the piezoelectric ceramic is elongated under the action of the electric field, the electric domains are turned to be aligned in spontaneous polarization, the alignment is aligned along the direction of the electric field, fig. 1 (c) is a graph after polarization treatment, the polarization intensities remained after polarization treatment are shown, and referring to fig. 2, fig. 2 is a schematic diagram of inverse piezoelectric effect, and the polarization directions are aligned along the direction of the electric field under the action of the electric field.

Referring to fig. 3, fig. 3 is a schematic diagram of a positive piezoelectric effect, which is a phenomenon in which electric polarization is generated due to deformation. When a physical pressure is applied to the piezoelectric material, the electric dipole moment in the material body becomes shorter due to compression, and when the piezoelectric material resists the change, equal positive and negative charges are generated on opposite surfaces of the material, so that the piezoelectric material is kept as it is, namely, an electric field is generated due to the stress.

Referring to fig. 4 and 5, an embodiment of the invention discloses an electronic device, which comprises a device main body 10, a first screen 11, a second screen 12 and a piezoelectric component 13, wherein the first screen 11, the second screen 12 and the piezoelectric component 13 are respectively arranged on the device main body 10, the second screen 12 and the first screen 11 are respectively positioned on different surfaces of the device main body 10, the device main body 10 comprises a first shell 18 and a second shell 19 which can rotate relatively, the first screen 11 is arranged on one side of the first shell 18, the second screen 12 is arranged on the other side of the first shell 18, the first shell 18 is provided with the piezoelectric component 13, and the piezoelectric component 13 positioned between the first shell 18 and the second shell 19 is pressed to wake up the second screen under the condition that the first shell 18 and the second shell 19 are folded.

Specifically, referring to fig. 6, the first screen 11 is a foldable screen of the electronic device, when the first screen 11 is folded, the first casing 18 where the first split screen 111 is located contacts the second casing 19 where the second split screen 112 is located, a mutual acting force is generated, the piezoelectric component 13 disposed under the first casing 18 and the second casing 19 is deformed under the action of pressure generated by contact, the deformation causes an electric polarization phenomenon to be generated inside the piezoelectric component 13, charges with opposite signs are generated on the surface of the piezoelectric component 13, a voltage difference is generated, an electric signal obtained according to the voltage can be used as an electric signal for waking up the second screen, when the acting force on the surface of the piezoelectric component 13 disappears, the piezoelectric component returns to an uncharged state, and the amount of electric charge generated on the surface of the piezoelectric component 13 is proportional to the received pressure. Therefore, if the piezoelectric element generates an electric charge, the first housing 18 and the second housing 19 are in a folded state, and the second screen can be awakened according to the generated electric signal, and if the piezoelectric element does not generate an electric signal, the first housing 18 and the second housing 19 are in an unfolded state, so that the second screen is not required to be awakened.

Specifically, the first magnetic element 14 and the second magnetic element 17 may be disposed at the rims of the first casing 18 and the second casing 19, where the first magnetic element 14 and the second magnetic element 17 are symmetrically disposed, after the first casing 18 and the second casing 19 are folded, so that the first casing 18 and the second casing 19 are tightly attached to each other, preventing the first casing 18 and the second casing 19 from being accidentally unfolded during carrying, and in addition, under the action of the first magnetic element 14 and the second magnetic element 17, the attachment between the first casing 18 and the second casing 19 becomes tighter, so that the pressure applied to the piezoelectric assembly 13 is greater, the piezoelectric assembly can work more reliably, and the second screen cannot be effectively awakened when the first casing 18 and the second casing 19 are folded due to insufficient pressure applied to the piezoelectric assembly. In addition, the front projection of the first magnetic element 14 on the plane of the first housing 18 overlaps with the front projection of the piezoelectric element 13 on the plane of the first housing 18, so that compared with a mode of matching the hall sensor with the magnet, the magnetic element can exert the maximum auxiliary force by matching the piezoelectric element with the magnetic element, and the number of the magnetic elements can be two mutually symmetrical, 4, 6 symmetrical, and the like. The embodiments of the present invention are not limited herein.
