The embodiment of the application provides a screen cloth, the screen cloth can be arranged in the earphone, the earphone can include wired earphone, bluetooth headset, in-ear earphone or hangers formula earphone etc. the embodiment of the application only uses the earphone is bluetooth headset for the example to explain, other types of earphone refer to the execution can.

Referring to fig. 1, a structural schematic diagram of a mesh fabric according to an embodiment of the present application is shown, referring to fig. 2, a structural schematic diagram of a knitting yarn according to an embodiment of the present application is shown, referring to fig. 3, a structural schematic diagram of a mesh fabric body according to an embodiment of the present application is shown, and referring to fig. 4, a schematic diagram of a B-B cross-section structure of a position a of the mesh fabric body shown in fig. 3 is shown.

Specifically, the mesh fabric specifically may include: a mesh body woven by the woven wires 10, and a circuit board 30 arranged around the edge of the mesh body; wherein the mesh body comprises a plurality of mesh openings 20; the braided wire 10 is made of piezoelectric material, and the braided wire 10 deforms under the condition that the braided wire 10 is introduced with adjusting voltage, so as to adjust the aperture of the mesh 20; the braided wire 10 is provided at both ends thereof with first conductive portions electrically connected to the circuit board 30 to input the regulated voltage through the circuit board 30, respectively.

In this embodiment, since the material of the braided wire 10 of the mesh cloth is a piezoelectric material, the braided wire 10 may be deformed under the condition that the braided wire 10 is supplied with the adjusting voltage, so as to adjust the aperture of the mesh 20. Therefore, when the mesh cloth is used for the earphone, the braided wire 10 can be driven to deform by controlling the adjusting voltage, and the aperture of the mesh 20 is adjusted, so that the purpose of adjusting the physical parameters of the earphone is achieved. Therefore, the earphone with the mesh cloth can still adjust physical parameters of the earphone in the using process, so that the tuning range is greatly widened, and a personalized tuning scheme is realized.

Specifically, the piezoelectric material from which the braided wire 10 is made may include, but is not limited to, materials of the titanium-zirconium-oxygen-lead series, the titanium-barium-oxygen series, and the like. The piezoelectric material expands and contracts the crystal structure of the substance by increasing the electric field, so that the braided wire 10 made of the piezoelectric material can deform under the condition of passing an adjusting voltage, and the deformation degree of the braided wire 10 is related to the magnitude of the adjusting voltage.

In this embodiment, since the mesh openings 20 on the mesh body are formed by the gaps between the braided wires 10 that are staggered, the pore diameters of the mesh openings 20 will be changed when the braided wires 10 are deformed. Thus, when the aperture needs to be adjusted, the braided wire 10 can be driven to deform by applying an adjustment voltage to the braided wire 10, the degree of deformation of the braided wire 10 can be controlled by controlling the magnitude of the adjustment voltage, and the aperture of the mesh 20 can be adjusted by the deformation of the braided wire 10.

In particular applications, the mesh may be used to cover functional holes of the earphone, which may include, but are not limited to, front cavity leakage holes, rear cavity leakage holes, horn leakage holes, and the like. The mesh may be used to adjust the acoustic resistance of the acoustic vibrations, thereby changing the frequency response of the earphone sound. In a specific application, the ventilation quantity and acoustic resistance of the corresponding functional holes can be adjusted by adjusting the mesh openings 20 on the mesh cloth, so as to achieve the purpose of adjusting the acoustic frequency response of the earphone.

In practical application, in the process of using the earphone by a user, a target frequency response curve favored by the user can be formed by acquiring tuning operation of the user. And analyzing the target frequency response curve to obtain corresponding mesh voltage parameters and EQ parameters. The control module on the earphone can input corresponding adjusting voltage to the braided wire 10 through the circuit board 30 of the mesh cloth and execute corresponding EQ parameter adjustment, so that the cooperative adjustment of physical parameters and electrical parameters of the earphone can be realized, the tuning range is widened, and a personalized tuning scheme is realized.

Alternatively, the deformation direction of the braided wire 10 is perpendicular to the axial direction (direction indicated by an arrow in fig. 2) of the braided wire 10, and specifically, the axial direction of the braided wire 10 may specifically be the length extending direction of the braided wire 10. In practical use, since the apertures of the mesh holes 20 formed between the braided wires 10 are related to the size of the sectional area of the braided wires 10 perpendicular to the axial direction. The larger the sectional area of the braided wires 10, the smaller the aperture of the mesh 20 formed between the braided wires 10. In the case that the deformation direction of the braided wire 10 is perpendicular to the axial direction of the braided wire 10, the deformation of the braided wire 10 can change the sectional area of the braided wire 10, and the aperture of the mesh 20 is correspondingly changed through the change of the sectional area of the braided wire 10, thereby achieving the purpose of adjusting the ventilation amount and the acoustic resistance.

In some optional embodiments of the present application, a cross section of the braided wire 10 perpendicular to the axial direction is a first width in the first direction, a width in the second direction is a second width, the first direction is perpendicular to the second direction, and the first direction is parallel to the surface of the mesh body; the first width is greater than the second width; upon input of the adjustment voltage, the braided wire 10 may be deformed in a telescopic manner in the first direction. In a specific application, the width of the braided wire 10 in the first direction has the greatest influence on the aperture of the mesh 20, so that when the adjustment voltage is input to cause the braided wire 10 to deform in a telescopic manner in the first direction, the deformation amount of the braided wire 10 can be converted into the variation amount of the width of the braided wire 10 in the first direction to the maximum extent, and the aperture of the mesh 20 can be changed to the maximum extent. Thus, the braided wire 10 can realize a larger adjusting range for the mesh 20 by a smaller deformation amount, and the aperture adjusting efficiency for the mesh 20 is improved.

It is to be understood that, in practical applications, those skilled in the art may set the cross-sectional shape of the braided wire 10 to be circular, rectangular, elliptical, or the like according to actual needs, and the cross-sectional shape of the braided wire 10 is not particularly limited in the embodiments of the present application.

As shown in fig. 3, the braided wire 10 is folded and arranged in this order along the first direction, and a plurality of folded portions are formed. Under the condition that the adjusting voltage is input, the flexible deformation of the braided wire 10 along the first direction can drive the folding part to be unfolded or folded along the first direction, so that the deformation of the braided wire 10 along the first direction and the movement of the folding part to be unfolded or folded along the first direction are overlapped, the deformation of the braided wire 10 along the first direction is increased, and the adjusting range of the mesh 20 is further improved.

Referring to fig. 5, a schematic structural diagram of a braided wire folded and deformed along a first direction is shown, and as shown in fig. 5, in the case that the braided wire 10 is folded and deformed along the first direction, the folded portion may be driven to fold along the first direction, so that the folding of the braided wire 10 along the first direction and the folded portion along the first direction are overlapped, the width of the braided wire 10 along the first direction is greatly reduced, and the aperture of the mesh 20 is increased.

Referring to fig. 6, a schematic structural view of a braided wire according to an embodiment of the present application is shown, which is deformed by being unfolded along a first direction. As shown in fig. 6, in the case that the braided wire 10 is stretched and deformed in the first direction, the folded portion may be driven to be stretched in the first direction, so that the stretched and folded portion of the braided wire 10 in the first direction is stretched laterally in the first direction, the width of the braided wire 10 in the first direction is greatly expanded, and the aperture of the mesh 20 is reduced.

In this embodiment, the material of the braided wire 10 is a piezoelectric material, and since the piezoelectric material has an inverse piezoelectric effect, the braided wire 10 also has an inverse piezoelectric effect. That is, when an external electric field is applied to the braided wire 10, the braided wire 10 may be deformed in one direction, and when the external electric field is reversed, the braided wire 10 may be deformed in the opposite direction.

Referring to fig. 7, a schematic structural view of a braided wire according to an embodiment of the present application deformed in a certain direction is shown, and referring to fig. 8, a schematic structural view of a braided wire according to an embodiment of the present application deformed in a direction opposite to that shown in fig. 7 is shown.

As shown in fig. 7, when a voltage in a certain direction is applied to the braided wires 10 in the mesh cloth, an electric field in the same direction may be applied to the braided wires 10, and at this time, the braided wires 10 may be deformed in a stretching manner along the first direction, and deformed from a state shown in a left drawing in fig. 7 to a state shown in a right drawing, so that the aperture of the mesh 20 enclosed between the braided wires 10 becomes smaller.

As shown in fig. 8, when a voltage in another direction is applied to the braided wires 10 in the mesh cloth, an electric field opposite to the direction of fig. 7 may be applied to the braided wires 10, and at this time, the braided wires 10 may shrink and deform in the first direction, from a state shown in the left drawing in fig. 8 to a state shown in the right drawing, so that the aperture of the mesh 20 enclosed between the braided wires 10 becomes large.

In this embodiment of the present application, since the deformation amount of the piezoelectric material is proportional to the voltage of the external electric field, the linear control of the deformation amount of the braided wire 10 can be achieved by controlling the voltage of the external electric field, so that the linear control of the pore diameter increase or decrease of the mesh 20 can be achieved, that is, the air permeability and acoustic resistance of the mesh can be controlled linearly, and the control precision of the air permeability and acoustic resistance of the mesh can be improved.

In order to avoid the adhesion layer 40 from affecting the adhesion between the second conductive portion 301 and the third conductive portion, the cross-sectional dimension of the avoiding hole 401 should be greater than or equal to the cross-sectional dimension of the second conductive portion 301, so that the second conductive portion 301 can be fully exposed.

In some alternative embodiments of the present application, the circuit board 30 is a flexible circuit board, and the first conductive portion is a flexible conductive portion. Because flexible circuit board with flexible conductive part all can take place deformation under the screen cloth body takes place the circumstances of deformation, flexible circuit board with flexible conductive part can take place the deformation correspondingly, offset the deformation of screen cloth body avoids screen cloth body and the junction of circuit board 30 forms stress concentration, improves the life of screen cloth.
