[0015] The embodiments of the present specification further describe a physiological signal detection device. In some embodiments, the physiological signal detection device may include the touch sensing device described above. The chamber of the touch sensing device is deformed by the action of the user's heartbeat, pulse, or respiratory vibration, and the deformation causes a change in air pressure in the chamber. The air pressure sensor receives the air pressure change in the chamber through the hole and converts the air pressure change into an electrical signal, and the physiological signal detection device can generate a physiological signal based on the electrical signal. In some embodiments, the physiological signal includes a heart rate, a pulse, or a respiratory rate.

[0016] 1 is a block diagram of a touch sensing device according to some embodiments of the present disclosure. As shown in FIG. 1, the touch sensing device 100 may include an air pressure sensor 110 and a sealing structure 120.

[0017] The touch sensing device 100 refers to a device that can convert the pressure applied by a user to a specific area into an electrical signal. For example, a user's touch operation is applied to the surface of the touch sensing device 100, and the touch sensing device 100 can generate an electrical signal based on the user's touch operation. In some embodiments, the touch operation may include, but is not limited to, a tap, a long press, a swipe, and the like. In some embodiments, the touch sensing device 100 may include a chamber, and when a user applies pressure to a certain area of ​​the touch sensing device 100, the structure of the area is deformed to change the air pressure inside the chamber, and a transducer (e.g., air pressure sensor 110) of the touch sensing device 100 can convert the air pressure change into an electrical signal.

[0018] The air pressure sensor 110 can generate an electrical signal based on the change in air pressure in the internal chamber of the touch sensing device 100. In some embodiments, the air pressure sensor 110 may have a hole, and the inside of the air pressure sensor 110 communicates with the chamber through the hole. When a touch operation acts on the surface of the touch sensing device 100, the air pressure in the internal chamber changes, and the change in air pressure in the internal chamber of the touch sensing device 100 is transmitted to the inside of the air pressure sensor 110 through the hole, and the air pressure sensor 110 can generate an electrical signal based on the change in air pressure inside.

[0019] In some embodiments, the air pressure sensor 110 may include a housing structure, a membrane structure, and a substrate. The housing structure has a cavity, and the membrane structure and the substrate are disposed within the cavity, one end of the substrate is connected to the housing structure, and the other end of the substrate is connected to the membrane structure. The membrane structure and the substrate divide the cavity into a front cavity and a rear cavity, the front cavity communicates with the outside of the air pressure sensor 110 through a hole, the air pressure in the front cavity changes in response to an air pressure change outside the air pressure sensor 110, and the membrane structure converts the air pressure change in the front cavity into an electrical signal. For example, the membrane structure may include a vibrating membrane structure, which vibrates and deforms in response to an air pressure change in the front cavity to generate an electrical signal in the magnetic circuit structure of the air pressure sensor 110. Also, for example, the membrane structure may include a piezoelectric layer, and when the membrane structure is deformed, the piezoelectric layer receives a deformation stress and generates a potential difference (voltage), thereby realizing the conversion from a touch signal to an electrical signal. In this specification, "connection" is understood as a connection between different parts of the same structure, or a fixed connection between each independent member or structure after manufacturing the different members or structures, such as by welding, riveting, fastening, bolting, gluing, or the like, or by depositing a first member or structure on a second member or structure in a manufacturing process by physical deposition (e.g., physical vapor deposition) or chemical deposition (e.g., chemical vapor deposition). Note that the air pressure sensor may be other sensors that can convert air pressure changes into an electrical signal. In some embodiments, the type of air pressure sensor may include, but is not limited to, any one or more of an air conduction microphone, a piezoelectric air pressure sensor, a capacitive air pressure sensor, a resistive air pressure sensor, and the like.

[0020] In some embodiments, the sealing structure 120 may be connected to the air pressure sensor 110, and a chamber is formed between the sealing structure 120 and the air pressure sensor 110, and the chamber communicates with a front cavity of the air pressure sensor 110 through a hole. A portion of the sealing structure 120 surrounding the chamber is deformed by a touch operation by a user, and the air pressure in the chamber changes due to the deformation, and the front cavity of the air pressure sensor 110 receives the air pressure change in the chamber through the hole, and the membrane structure is deformed by the air pressure change to generate an electrical signal.

[0021] When the gas is in ideal balance, the following relationship exists between the pressure, volume, and temperature of the chamber:

[0022] pV=nRT (1)

[0023] In equation (1), p is pressure (unit: Pa), V is the volume of the gas (unit: m3), T is temperature (unit: K), n is the amount of gas substance (unit: mol), and R is the gas constant (also called the ideal gas constant) (unit: J / (mol K)).

[0024] When the amount of gas is constant, i.e., the amount of substance of the gas is a certain constant and the temperature is constant, the pressure-volume relationship can be further expressed as follows:

[0025] p1V1=p2V2(2)

[0026] In formula (2), the relationship between the air pressure and the chamber volume before and after the air pressure in the chamber changes can be expressed. That is, for a gas in a sealed chamber, the change in the volume of the chamber can be measured by the change in the air pressure in the chamber. Therefore, when the part of the sealing structure 120 surrounding the chamber is deformed by the touch operation of the user, that is, the volume of the chamber changes, and the air pressure in the chamber changes.

[0027] In some embodiments, the sealing structure 120 may be a hollow structure with an open opening at one end, the one end of the sealing structure 120 being a sealed end, the sealing structure 120 may be fitted to the outside of the air pressure sensor 110, the end of the sealing structure 120 away from the sealed end being connected to the housing structure of the air pressure sensor 110, and the sealed end of the sealing structure 120 is spaced apart from the end of the air pressure sensor 110 adjacent to the sealed end, and the sealing structure 120 and the end of the air pressure sensor 110 adjacent to the sealed end are enclosed to form a chamber. In some embodiments, the sealing structure 120 may be a flexible material such that the sealing structure 120 can be deformed by the user's touch to change the air pressure in the chamber. In some embodiments, the flexible material may include rubber, latex, silica gel, sponge, polyethylene, polyester, polyimide, polyethylene naphthalate, and the like, or any combination thereof.

[0028] In some embodiments, the sealing structure 120 may include a connecting portion 121 and a membrane-like structure 122. In some embodiments, the connecting portion 121 may be a cylindrical structure with both ends penetrated, and is fitted on the outside of the air pressure sensor 110, and the membrane-like structure 122 is connected to one end of the connecting portion 121 and is spaced apart from one end of the air pressure sensor 110. In some embodiments, the connecting portion 121 and the membrane-like structure 122 form a chamber together with an end of the air pressure sensor 110 having a hole, and the chamber communicates with the front cavity of the air pressure sensor 110 through the hole. In some embodiments, the membrane-like structure 122 may be a flexible material, and the connecting portion 121 may be a flexible material or a rigid material. Exemplary rigid materials may include metal materials, styrene-butadiene-acrylonitrile copolymers, glass, ceramics, etc., or any combination thereof. If the connection part 121 is a flexible material, the user can contact the connection part 121 or the membrane-like structure 122 to deform the sealing structure 120, and if the connection part 121 is a rigid material, the user can change the air pressure in the chamber by contacting the membrane-like structure 122 to deform the membrane-like structure 122. In some embodiments, one end of the connection part 121 of the sealing structure 120 may be connected to one end of the air pressure sensor 110, and the other end of the connection part 121 is connected to the membrane-like structure 122, and the ends of the membrane-like structure 122, the connection part 121, and the air pressure sensor 110 form a chamber.

[0029] When the user's touch operation acts on the region of the sealing structure 120 or the membrane structure 122 corresponding to the chamber in the touch sensing device 100, the region of the sealing structure 120 or the membrane structure 122 corresponding to the chamber is deformed, the volume of the chamber is changed, and the air pressure in the chamber is changed. The change in air pressure in the chamber affects the change in air pressure in the front cavity of the air pressure sensor 110 through the hole, and the membrane structure is deformed in response to the change in air pressure in the front cavity to generate an electric signal, thereby realizing touch sensing for the user. Due to the flexibility of the sealing structure 120, a small pressure applied by the user causes a large volume deformation in the chamber, so that the touch sensing device 100 has high sensitivity and can meet practical needs.

[0030] For more detailed description of the touch sensing device, please refer to other parts of this specification, for example, Figures 2 to 5B and related descriptions thereof. Hereinafter, the touch sensing device will be described by way of example with reference to Figures 2 to 5B.

[0031] FIG. 2 is an exemplary structural diagram of a touch-sensing device according to some embodiments of the present disclosure.

[0032] As shown in FIG. 2, in some embodiments, the touch sensing device 200 includes a sealing structure 220 and an air pressure sensor 210. The sealing structure 220 is a cylindrical structure with an open opening, and the end of the sealing structure 220 away from the opening is a sealed end 221. In some embodiments, the sealing structure 220 may be a structure with a regular shape, such as a rectangular parallelepiped, a sphere, a polygonal body, a pyramid frustum, or any irregular shape. In some embodiments, a sidewall corresponding to the hollow area inside the sealing structure 220 may be connected to the outer periphery of the housing structure 211, where the hollow area inside the sealing structure 220 is adapted to the shape and size of the housing structure 211 so that the air pressure sensor 210 can seal the opening. In some embodiments, at least a part of the air pressure sensor 210 is provided inside the sealing structure 220 through the opening, so that the sealing structure 220 is fitted to the outside of the air pressure sensor 210 and the opening of the sealing structure 220 is sealed. For example, a part of the structure of the air pressure sensor 210 is provided inside the sealing structure 220 through the opening, and another part of the structure of the air pressure sensor 210 protrudes outside the sealing structure 220 relative to the opening. Also, for example, the entire air pressure sensor 210 is provided inside the sealing structure 220. In some embodiments, an end of the air pressure sensor 210 facing the position of the sealed end 221 of the sealing structure 220 has a hole 215, and the end of the air pressure sensor 210 where the hole 215 is located is provided at a distance from the sealed end 221 of the sealing structure 220, so that the sealing structure 220 and the end where the hole 215 is located form a chamber 230. In some embodiments, the sealed end 221 may be manufactured from a flexible material. Exemplarily, the flexible material may include rubber, latex, silica gel, sponge, polyethylene, polyester, polyimide, parylene, polydimethylsiloxane, polyethylene naphthalate, etc., or any combination thereof. The sensitivity of the touch sensing device 200 is related to the ability of the sealing structure 220, especially its sealed end 221, to deform, and the ability of the sealing structure 220 and its sealed end 221 to deform is related to factors such as the Young's modulus of the material, thickness, etc. In order to ensure that the sealing structure 220 has a high deformation ability and thus the sensitivity of the touch sensing device 200, in some embodiments, the Young's modulus of the flexible material may be less than 50 GPa.For example, if the flexible material is silica gel, its Young's modulus may be about 1.2 GPa, and if the flexible material is parylene, its Young's modulus is about 3.2 GPa.

[0033] In order to prevent the pressure change inside the chamber 230 from acting on the housing structure 211 of the pressure sensor 210 and deforming it, thereby changing the volume of the front cavity 216, in some embodiments, a hard material is used as the material of the housing structure 211 of the pressure sensor 210. Exemplarily, the hard material may include, but is not limited to, one or more of metals (e.g., copper, platinum, steel, aluminum), non-metallic materials (e.g., diamond, ceramic, silicon material, etc.), alloys, etc. In some embodiments, the Young's modulus of the housing structure 211 is about 60 GPa to 1200 GPa. In some embodiments, the Young's modulus of the housing structure 211 is about 100 GPa to 800 GPa. In some embodiments, the Young's modulus of the housing structure 211 is about 200 GPa to 600 GPa. In some embodiments, the materials of the housing structure 211 and the closed end 221 may be limited using other parameters to prevent the volume of the front cavity 216 from changing, and in some embodiments, the ratio of the Young's modulus of the material corresponding to the closed end 221 to the Young's modulus of the material corresponding to the housing structure 211 may be 0.002 to 0.01. Preferably, the ratio of the Young's modulus of the material corresponding to the closed end 221 to the Young's modulus of the material corresponding to the housing structure 211 may be 0.005 to 0.01. More preferably, the ratio of the Young's modulus of the material corresponding to the closed end 221 to the Young's modulus of the material corresponding to the housing structure 211 may be 0.008 to 0.01.

[0034] In some embodiments, the air pressure sensor 210 may include a housing structure 211, a membrane structure 213, and a base 212. The housing structure 211 is a hollow structure, the hollow region of the housing structure 211 is a cavity of the housing structure 211, and the membrane structure 213 and the base 212 are disposed within the cavity. In some embodiments, the shape of the housing structure 211 of the air pressure sensor 210 may include, but is not limited to, a regular shape such as a rectangular parallelepiped, a sphere, a polygonal body, a truncated pyramid, or any irregular shape. In some embodiments, the base 212 may be a structure with an open opening at one end, the membrane structure 213 is located in and covers the opening, and the other end of the base 212 is connected to the housing structure 211 to divide the cavity into a front cavity 216 and a rear cavity 217. In some embodiments, the substrate 212 may be a cylindrical structure with both ends open, both ends of the substrate 212 having an opening, one end of the substrate 212 is connected to the housing structure 211, and the other end of the substrate 212 is connected to the membrane structure 213, and the membrane structure 213 seals the opening at the end of the substrate 212 where it is located. In some embodiments, the shape of the opening of the substrate 212 may include, but is not limited to, a regular shape such as a circle, a rectangle, an ellipse, a semicircle, a polygon, or any irregular shape. The shape of the membrane structure 213 may include, but is not limited to, a regular shape such as a circle, a rectangle, an ellipse, a semicircle, a polygon, or any irregular shape. In some embodiments, the size of the membrane structure 213 may be larger than the size of the opening of the substrate 212 such that the membrane structure 213 seals the opening at the end of the substrate 212 where it is located. In some embodiments, the membrane structure 213 may be connected via its outer periphery to a sidewall corresponding to the opening of the substrate 212, where the membrane structure 213 conforms to the shape and size of the opening of the substrate 212.

[0035] The chamber 230 communicates with the front cavity 216 through the hole 215, and the air pressure in the chamber 230 can affect the air pressure in the front cavity 216 through the hole 215, i.e., when the air pressure in the chamber 230 changes, the air pressure in the front cavity 216 changes accordingly. The membrane structure 213 can deform in response to the change in air pressure in the front cavity 216. The sensitivity of the touch sensing device 200 is related to the volume of the chamber 230 and the front cavity 216 of the air pressure sensor 210, and in some embodiments, the volume of the chamber 230 may be equal to or less than the volume of the front cavity 216 of the air pressure sensor 210 to improve the sensitivity of the touch sensing device 200. Preferably, the volume ratio of the chamber 230 to the front cavity 216 is 0.2 to 0.8 to further improve the sensitivity of the touch sensing device 200. More preferably, the volume ratio between the chamber 230 and the front cavity 216 is 0.3 to 0.7. More preferably, the volume ratio between the chamber 230 and the front cavity 216 is 0.5 to 0.6. In some embodiments, the sensitivity of the touch sensing device 200 may be adjusted by adjusting the size of the chamber 230 (e.g., height, length, width, or radius), the size of the front cavity 216, and the size of the internal components of the air pressure sensor 210 (e.g., the base 212, the membrane structure 213). For example, when the sealing structure 220 and the housing structure 211 of the air pressure sensor 210 are both columnar structures (e.g., a cylinder, a rectangular parallelepiped), the thickness of the sidewall of the housing structure 211 is small, so that the bottom areas of the chamber 230 and the front cavity 216 can be considered to be approximately equal. In this case, the height of the chamber 230 (the size in the direction perpendicular to the sealing end 221) may be equal to or less than the height of the front cavity 216 inside the air pressure sensor 210. Also, for example, the height of chamber 230 may be approximately equal to the height of air pressure sensor 210, and one of the other dimensions (e.g., length, width or radius) of chamber 230 may be less than or equal to 1 / 5 of another size of front cavity 216 in air pressure sensor 210.It should be noted that the above content is an exemplary explanation of the volume of the chamber 230 being equal to or less than the volume of the front cavity 216, and any content by a person skilled in the art to make the volume of the chamber 230 equal to or less than the volume of the front cavity 216 by other adjustment methods is within the scope of protection of this specification.

[0036] In some embodiments, the air pressure sensor may be an air conduction microphone. Based on the principle of the air conduction microphone, the air conduction microphone may include one or more of a moving coil microphone, a ribbon microphone, a condenser microphone, an electret microphone, a piezoelectric microphone, etc. Taking the moving coil microphone as an example of an air pressure sensor, the membrane structure 213 may be a vibrating membrane structure, and the air conduction microphone may further include a magnetic circuit structure, and the vibrating membrane structure and the magnetic circuit structure are connected through a voice coil. The vibrating membrane structure vibrates and deforms in response to the change in air pressure in the front cavity 216, and the voice coil moves regularly with the vibration of the vibrating membrane structure, and the movement of the voice coil can generate an electric signal in the magnetic circuit structure, thereby realizing the conversion from the touch signal to an electric signal. In some embodiments, the vibrating membrane structure may be a plastic film such as a PVC film or a polyethylene film. A piezoelectric microphone is described as another example of the air pressure sensor, and in some embodiments, the membrane structure 213 may include a piezoelectric layer, and when the membrane structure 213 is deformed, the piezoelectric layer is subjected to deformation stress to generate a potential difference (voltage), thereby realizing the conversion of the touch signal into an electrical signal. In some embodiments, the membrane structure 213 may include a piezoelectric layer and an electrode layer, and the electrode layer may be located on the upper surface and / or the lower surface of the piezoelectric layer. When the membrane structure 213 is deformed, the piezoelectric layer can generate a potential difference under the action of deformation stress based on the piezoelectric effect, and the electrode layer can collect the potential difference to generate an electrical signal.

[0039] It should be noted that the above description of the touch sensing device 200 and its components is merely for illustrative purposes and does not limit the scope of application of the present specification. Those skilled in the art may make various modifications and changes to the touch sensing device 200 under the guidance of the present specification. In some embodiments, the hole 215 may also be located on other side walls of the air pressure sensor 210, and is not limited to the side wall facing the sealed end 221 of the air pressure sensor 210. For example, the sealing structure 220 may be a cylindrical structure, the air pressure sensor 210 may be a truncated cone structure, and the hole 215 may be located on the side wall of the truncated cone structure. Also, for example, the sealing structure 220 may be a truncated pyramid structure, the air pressure sensor 210 may be a rectangular parallelepiped structure, and the hole 215 may be located on the side wall facing the pyramid side of the truncated pyramid structure of the rectangular parallelepiped structure. These modifications and changes are within the scope of the present specification. These modifications and changes may also be applied to the touch sensing device 300 shown in FIGS. 3A and 3B, the touch sensing device 400 shown in FIG. 4, and the touch sensing device 500 shown in FIGS. 5A and 5B.

[0040] Fig. 3A is an exemplary structural diagram of a touch sensing device according to some embodiments of the present disclosure. Fig. 3B is an exemplary structural diagram of a touch sensing device according to some other embodiments of the present disclosure. Fig. 3C is an exemplary structural diagram of a touch sensing device according to some other embodiments of the present disclosure.

[0041] 3A to 3C are similar to the structures of the air pressure sensor 210 and its housing structure 211, base 212, membrane structure 213, first processor 214, etc. shown in Fig. 2, and therefore will not be described here. Touch sensing device 300 differs from touch sensing device 200 in that the sealing structures are different.

[0042] As shown in FIGS. 3A, 3B, and 3C, the sealing structure 320 may include a connecting portion 321 and a membrane-like structure 322. In some embodiments, the connecting portion 321 is a cylindrical structure with both ends penetrated, and has a first end 3211 and a second end 3212, i.e., the first end 3211 and the second end 3212 of the connecting portion 321 both have open openings. In some embodiments, the connecting portion 321 may be a structure with a regular shape, such as a rectangular parallelepiped, a sphere, a polygonal body, a truncated pyramid, or a structure with any irregular shape. In some embodiments, a sidewall corresponding to the internal hollow region of the connecting portion 321 may be connected to the outer periphery of the housing structure 311, where the internal hollow region of the connecting portion 321 is adapted to the shape and size of the housing structure 311 so that the air pressure sensor 310 can seal the opening. At least a part of the air pressure sensor 310 is provided inside the connection part 321 through the opening of the second end 3212, so that the connection part 321 is fitted to the outside of the air pressure sensor 310 and the opening corresponding to the second end 3212 of the connection part 321 is sealed. For example, a part of the structure of the air pressure sensor 310 is provided inside the connection part 321 through the opening of the second end 3212, and the other part of the structure of the air pressure sensor 310 protrudes outside the connection part 321 with respect to the opening of the second end 3212. Also, for example, the entire air pressure sensor 310 is provided inside the connection part 321. The membrane structure 322 is located at the opening of the first end 3211 and covers the opening. The membrane structure 322 and the end of the air pressure sensor 310 where the hole 315 is located are provided at a distance from each other, so that the connection part 321, the membrane structure 322, and the end of the air pressure sensor where the hole 315 is located form a chamber 330.

[0043] As shown in FIG. 3A, in some embodiments, the membranous structure 322 may cover and seal the opening of the first end 3211, so as to form a chamber 330 together with the connecting portion 321 and the housing structure 311. The size of the membranous structure 322 here is larger than the size of the opening of the connecting portion 321, so that the membranous structure 322 seals the opening of the first end 3211. In some embodiments, as shown in FIG. 3B, the membranous structure 322 may be connected to a sidewall corresponding to the opening of the connecting portion 321 via its outer periphery, and the membranous structure 313 here fits the shape and size of the opening of the base 312.

[0044] As shown in FIG. 3C, in some embodiments, the sealing structure 320 may further include a support portion 323, which is a plate-like structure having a hole opening, and the support portion 323 is provided at a distance from the end where the hole portion 315 of the air pressure sensor 310 is located. In some embodiments, the outer periphery of the support portion 323 is connected to a sidewall corresponding to the opening of the connection portion 321, and the support portion 323 matches the shape and size of the opening of the connection portion 321. In some examples, the membrane-like structure 322 may cover and seal the hole opening of the support portion 323, and the connection portion 321 and the membrane-like structure 322 together with the end having the hole portion 315 of the air pressure sensor 310 form a chamber 330. The support portion 323 can support the membrane-like structure 322 so as to improve the stability of the membrane-like structure 322. In some embodiments, the side of the membranous structure 322 close to the air pressure sensor 310 may be connected to the side of the support 323 away from the air pressure sensor 310, and the support 323 provides a larger connection area for the membranous structure 322 to improve the stability of the membranous structure 322. In some embodiments, the side of the membranous structure 322 away from the air pressure sensor 310 may be connected to the side of the support 323 close to the air pressure sensor 310. In some embodiments, when the membranous structure 322 is connected to the support 323, the outer periphery side of the membranous structure 322 may be simultaneously connected to the sidewall corresponding to the opening of the connection 321 to further improve the stability of the membranous structure 322.

[0045] In some embodiments, the membrane structure 322 may be a flexible material, and the connection part 321 may also be a flexible material, and the user can change the air pressure in the chamber 330 by touching any position of the membrane structure 322 or the connection part 321 surrounding the chamber 330 to deform the part surrounding the chamber 330 of the sealing structure 320. In some embodiments, the membrane structure 322 may be a flexible material, and the connection part 321 may be a rigid material, and the user can change the air pressure in the chamber 330 by touching any position of the part surrounding the chamber 330 of the membrane structure 322 to deform the chamber 330 of the membrane structure 322. Furthermore, the chamber 330 communicates with the front cavity through the hole part 315, and the air pressure in the chamber 330 can affect the air pressure in the front cavity through the hole part 315, i.e., when the air pressure in the chamber 330 changes, the air pressure in the front cavity changes accordingly.

[0046] In some embodiments, the membrane structure 322 may be made of a flexible material. Exemplarily, the flexible material may include rubber, latex, silica gel, sponge, polyethylene, polyester, polyimide, parylene, polydimethylsiloxane, polyethylene naphthalate, and the like, or any combination thereof. The sensitivity of the touch sensing device 300 is related to the deformation capacity of the membrane structure 322, and the deformation capacity of the membrane structure 322 is related to factors such as the Young's modulus and thickness of the material. In order to ensure the sensitivity of the touch sensing device 300 by having the membrane structure 322 have a high deformation capacity, in some embodiments, the Young's modulus of the flexible material may be less than 50 GPa. For example, if the flexible material is silica gel, the Young's modulus may be about 1.2 GPa. Also, for example, if the flexible material is parylene, the Young's modulus is about 3.2 GPa. In some embodiments, the thickness of the membrane structure 322 is in the range of 0.05 mm to 0.3 mm. Preferably, the thickness of the membranous structure 322 is in the range of 0.1 mm to 0.2 mm.

[0047] In order to prevent the change in the air pressure inside the chamber 330 from acting on the housing structure 311 of the air pressure sensor 310 and deforming it, thereby changing the volume of the front cavity 316, in some embodiments, the material of the housing structure 311 of the air pressure sensor 310 is a hard material. Exemplarily, the hard material may include, but is not limited to, one or more of metals (e.g., copper, platinum, steel, aluminum), non-metallic materials (e.g., diamond, ceramic, silicon material, etc.), alloys, etc. In some embodiments, the Young's modulus of the housing structure 311 is about 60 GPa to 1200 GPa. In some embodiments, the Young's modulus of the housing structure 311 is about 100 GPa to 800 GPa. In some embodiments, the Young's modulus of the housing structure 311 is about 200 GPa to 600 GPa. In some embodiments, the materials of the housing structure 311 and the membrane structure 322 may be limited using other parameters to prevent the volume of the front cavity 316 from changing, and in some embodiments, the ratio of the Young's modulus of the material corresponding to the membrane structure 322 to the Young's modulus of the material corresponding to the housing structure 311 may be 0.002 to 0.01. Preferably, the ratio of the Young's modulus of the material corresponding to the membrane structure 322 to the Young's modulus of the material corresponding to the housing structure 311 may be 0.005 to 0.01. More preferably, the ratio of the Young's modulus of the material corresponding to the membrane structure 322 to the Young's modulus of the material corresponding to the housing structure 311 may be 0.008 to 0.01.

[0048] Exemplary flexible materials may include rubber, latex, silica gel, sponge, etc., or any combination thereof. Exemplary rigid materials may include metallic materials, styrene-butadiene-acrylonitrile copolymers, glass, ceramics, etc., or any combination thereof.

[0049] FIG. 4 is an exemplary structural diagram of a touch-sensing device according to some embodiments of the present disclosure.

[0050] The air pressure sensor 410, its housing structure 411, its base 412, its membrane structure 413, its first processor 414, its membrane structure 422, and its connection part 421 shown in FIG. 4 are similar to the air pressure sensor 310, its housing structure 311, its base 312, its membrane structure 313, its first processor 314, its membrane structure 322, its connection part 321, and the like shown in FIG. 3A, and therefore will not be described here. The touch sensing device 400 and the touch sensing device 300 differ mainly in that the connection position between the connection part 421 and the housing structure 411 is different. The side wall corresponding to the hollow area inside the connection part 421 is connected to the outer periphery of the housing structure 411, and a part of the structure of the air pressure sensor 410 is provided inside the connection part 421 through an opening, and the structure of the other part of the air pressure sensor 410 protrudes outside the connection part 421 through the opening. In some embodiments, a portion of the end face of the connecting portion 421 away from the membrane structure 422 may be connected to an end face of the housing structure 411 having the hole 415 .

[0051] 5A and 5B are exemplary structural diagrams of a touch-sensing device according to some embodiments of the present disclosure, respectively.

[0052] 5A and 5B, the air pressure sensor 510 and its housing structure 511, the base 512, the membrane structure 513, the first processor 514, and the membrane-like structure 522 and the connection part 521 of the sealing structure 520 are similar to the air pressure sensor 310 and its housing structure 311, the base 312, the membrane structure 313, the first processor 314, and the membrane-like structure 322 and the connection part 321 shown in FIG. 3A, and therefore the description thereof will be omitted here. The touch sensing device 500 and the touch sensing device 300 are mainly different in that the connection position between the connection part 521 and the housing structure 511 is different. The end face of the connection part 521 away from the membrane-like structure 522 is connected to the end face having the hole part 515 of the housing structure 511, so that the spatial size of the touch sensing device 500 can be reduced.

[0053] In some embodiments, in order to flatten the entire structure of the touch sensing device 500, the outer periphery side of the connection portion 521 may be flush with the outer periphery side of the housing structure 511. In some embodiments, the outer periphery side of the connection portion 521 may be provided to protrude from the outer periphery side of the housing structure 511, or may be provided to be recessed into the outer periphery side of the housing structure 511.

[0054] In some embodiments, as shown in Fig. 5A, the surface of the membrane structure 522 adjacent to the air pressure sensor 510 is connected to the surface of the connection part 521 adjacent to the membrane structure 522, where the size of the membrane structure 522 is larger than the size of the opening of the connection part 521 so that the membrane structure 522 seals the opening of the end of the connection part 521 where it is located. In some embodiments, as shown in Fig. 5B, the membrane structure 522 may be connected to a sidewall corresponding to the opening of the connection part 521 through its outer periphery, where the membrane structure 513 fits the shape and size of the opening of the base 512.

[0055] In some embodiments, the membrane structure of the air pressure sensor may be a membrane structure made of a breathable material. For example, the membrane structure may be made of polyvinylidene fluoride, polyurethane, PDMS organosilicon. In some embodiments, the membrane structure of the air pressure sensor may further be provided with at least one vent hole. By using a membrane structure made of a breathable material or a method of providing a vent hole in the membrane structure, the membrane structure can communicate with the front cavity and the rear cavity of the air pressure sensor, in which case, when a user taps or presses and holds a sealing structure or a membrane-like structure corresponding to a chamber in the touch sensing device, the impact on the membrane structure caused by the change in air pressure in the chamber is temporary, and the membrane structure is deformed, generating an electrical signal as a spike. In an actual application scene of the touch sensor according to the embodiment (for example, applied to devices such as earphones, mobile phones, smart watches, tablet computers, etc.), when a user taps or presses a part corresponding to a chamber in the touch sensing device multiple times (for example, a sealed structure, a membrane structure), the air pressure sensor generates a spike signal corresponding to the number of times the user operates in response to the user's tap or press and hold operation, thereby reducing the influence of the membrane structure on the continuous touch, facilitating the calculation of the number of times the user taps or presses and holds the touch sensing device, and further realizing accurate control of the application subject of the touch sensing device according to the number of times the user acts on the touch sensing device. For example, the application subject of the touch sensing device is an earphone, and when the number of times the user acts on the touch sensing device is one, the audio volume output from the earphone can be adjusted. Also, for example, when the number of times the user acts on the touch sensing device is at least two, the progress of the audio output from the earphone (pause, start, fast forward or rewind) can be adjusted or the audio output from the earphone can be replaced. In some embodiments, the membrane structure of the air pressure sensor may be a membrane structure made of a non-breathable material.In this case, the membrane structure can isolate the front cavity and the rear cavity of the air pressure sensor, and when a user taps or presses the sealing structure of the touch sensing device for a long time, the change in air pressure generated in the chamber can affect the membrane structure, causing the membrane structure to deform and generate an electrical signal. When a user taps the sealing structure or membrane structure corresponding to the chamber in the touch sensing device, the impact on the membrane structure due to the change in air pressure in the chamber is temporary, causing the membrane structure to deform and generate an electrical signal as a spike. When a user presses and holds the sealing structure or membrane structure corresponding to the chamber in the touch sensing device for a long time, the change in air pressure in the chamber can be held for a certain period of time accordingly, and the impact on the membrane structure is also sustained, causing the membrane structure to deform and generate an electrical signal as a plateau peak. In an actual application scene of the touch sensor according to the embodiment (for example, applied to devices such as earphones, mobile phones, smart watches, and tablet computers), when a user taps or presses a portion (for example, a sealed structure, a membrane structure) corresponding to a chamber in the touch sensing device multiple times, the air pressure sensor generates a spike signal or a plateau peak corresponding to the number of operations of the user in response to the user's tap or press and hold operation, and the user can then act on the touch sensing device to realize accurate control over the application subject of the touch sensing device. For example, the application subject of the touch sensing device is an earphone, and when the user taps the touch sensing device, the volume of the audio output from the earphone can be adjusted. Also, for example, when the user presses and holds the touch sensing device, the progress (pause, start, fast forward, or rewind) of the audio output from the earphone can be adjusted, or the audio output from the earphone can be replaced. For specific applications of the touch sensing device, reference can be made to other parts of the specification of this application, for example, FIG. 10 to FIG. 12 and related descriptions thereof.

[0056] 6 is a diagram of an electrical signal generated by a touch sensing device according to some embodiments of the present disclosure. As shown in FIG. 6, when the membrane structure of the air pressure sensor is made of a breathable material, when a user taps or presses long on a sealing structure or a membrane structure corresponding to a chamber in the touch sensing device, the membrane structure is deformed to generate an electrical signal as a spike 61. When the membrane structure of the air pressure sensor is made of a non-breathable material, when a user taps on a sealing structure or a membrane structure corresponding to a chamber in the touch sensing device, the membrane structure is deformed to generate an electrical signal as a spike 61, and when a user presses long on a sealing structure or a membrane structure corresponding to a chamber in the touch sensing device, the membrane structure is deformed to generate an electrical signal as a plateau peak 62.

[0057] In addition, the solution in which the membrane structure uses a breathable or non-breathable material can be applied to other embodiments in this specification, such as the touch sensing device 200 shown in FIG. 2, the touch sensing device 300 shown in FIGS. 3A-3B, the touch sensing device 400 shown in FIG. 4, and the touch sensing device 500 shown in FIGS. 5A and 5B.

[0058] The embodiments of the present specification further provide a sensing device for recognizing a user's gesture, which can recognize a swipe gesture performed by a user on an application device (e.g., an earphone, a mobile phone, a tablet computer, a smart watch, etc.). Hereinafter, the sensing device for recognizing a user's gesture will be described with reference to FIG. 7.

[0059] FIG. 7 is a block diagram of a sensing device for recognizing a user's gesture according to some embodiments of the present application. As shown in FIG. 7, the sensing device 700 for recognizing a user's gesture may include a touch sensing assembly 710 and a second processor 720. In some embodiments, the touch sensing assembly 710 may include a first touch sensing device 711, a second touch sensing device 712, ... an n-th touch sensing device 71n. n is an integer greater than 1, and a description of any one of the touch sensing devices among the first touch sensing device 711, the second touch sensing device 712, ... the n-th touch sensing device 71n may refer to the description of any one of the touch sensing devices in FIG. 1 to FIG. 6. The description will be omitted here. A user's swipe operation (successive contacts) sequentially passes through at least two touch sensing devices in the touch sensing assembly 710, which in response generate electrical signals, and the second processor 720 determines the swipe direction of the user's gesture based on the position information of the at least two touch sensing devices and the generation times of the electrical signals.

[0060] In some embodiments, the position information of the plurality of touch sensing devices may be pre-stored in the second processor 720 to facilitate the second processor 720 to directly obtain the position information of the touch sensing device generating the electrical signal. The second processor 720 receives the electrical signal, i.e., obtains the position information of the corresponding touch sensing device, and determines the swipe direction of the user's gesture in the order of receiving the electrical signal. For example, the positions of the first touch sensing device, the second touch sensing device, and the third touch sensing device are point A, point B, and point C, respectively, and the second processor sequentially receives the electrical signals of the second touch sensing device, the first touch sensing device, and the third touch sensing device, and can determine that the swipe direction of the user's gesture is from point B to point A to point C. In some embodiments, the sensing device 700 for recognizing a user's gesture may further include a memory (not shown) capable of storing the position information of the plurality of touch sensing devices. Upon receiving the electrical signal, the second processor 720 can obtain the position information of the corresponding touch sensing device from the memory.

[0061] In some embodiments, the sensing device 700 for recognizing a user's gesture may further include a timer (not shown) for marking a real-time time, and the second processor 720 may read the real-time time from the timer. The second processor 720 may read the real-time time from the timer immediately after receiving the electrical signal, and determine the swipe direction of the user's gesture in combination with the position information of the touch sensing device corresponding to the electrical signal. For example, the positions of the first touch sensing device, the second touch sensing device, and the third touch sensing device are point A, point B, and point C, respectively, and the times at which the first touch sensing device, the second touch sensing device, and the third touch sensing device generate electrical signals are time a, time b, and time c, respectively, where c>a>b, and the second processor may determine that the swipe direction of the user's gesture is from point B to point A to point C.
