But at the same time, there is a clear polarization in the sleep duration of Chinese residents, and the gap between the shortest and longest sleep durations is gradually widening. Shallow sleep and easy awakening are the most common sleep problems at present. Nearly half of the people sleep less than 8 hours per night on average, and the average sleep duration of less than 7 hours per night still accounts for a large proportion of the people, accounting for 16.79%. More than 90% of the people often or occasionally encounter sleep quality problems, the main problems include shallow sleep and difficulty falling asleep. Shallow sleep, difficulty falling asleep and easy awakening are the most common sleep quality problems.

[0048] The following embodiments of the present application provide an intelligent sleep-aiding device that is comfortable to wear for a long time and has a good sleep-aiding effect.

[0049] like Figure 1 As shown, this embodiment provides an intelligent sleep-aiding device 100, which includes a host 110, a headband 120 and an earphone 130.

[0050] Specifically, the headband is a band-shaped structure with elastic expansion and contraction function, and its elastic expansion and contraction function is suitable for wearing on heads of various sizes. Figure 1 As shown, the headband 120 has a front end 121, two side ends 122 and a rear end 123. The front end 121 is worn in front of the head and matched with the host. The two side ends 122 are worn on the left and right sides of the head and are located near the ears. The two side ends 122 are respectively connected to an earphone 130.

[0051] like Figure 2As shown, further, the inner and outer moving angle range formed by the earphone part 130 moving to the inner side of the side end portion to the maximum angle and moving to the outer side of the side end portion to the maximum angle is 30 degrees. The protection scope of this application is not limited to the inner and outer moving angle range values ​​listed in this embodiment, and all angle ranges formed by the expansion of the prior art made according to the technical principle of this application are included in the protection scope of this application.

[0052] In one embodiment of the present application, the earphone portion moves forward or backward of the side end portion through a connection point with the side end portion.

[0053] like Figure 3 As shown, further, the front-to-back moving angle range formed by the earphone part 130 moving to the front of the side end to the maximum angle and moving to the rear of the side end to the maximum angle is 40 degrees. The protection scope of this application is not limited to the front-to-back moving angle range values ​​listed in this embodiment, and all angle ranges formed by the expansion of the prior art made according to the technical principle of this application are included in the protection scope of this application.

[0054] Specifically, the earphone part can be adapted to the subject's ear being located at the front or back of the head by moving the connection point with the side end part toward the front or back of the side end part, thereby satisfying the personal habits of users with different ear positions and wearing the earphones forward or backward.

[0055] In one embodiment of the present application, the intelligent sleep aid device further includes a first fixing structure, which is built into the side end of the headband portion or is an integral structure with the side end of the headband portion; the earphone portion is matched and connected with the first fixing structure. The first fixing structure includes a fixing plate, a fixing member, a first control motor and a second control motor; the fixing plate is mechanically connected to the earphone portion, the first control motor and / or the second control motor through the fixing member. In this embodiment, the fixing member may be one or more and may be any type of fixing member structure commonly used in the art, such as bolts, screws, nuts, rivets, pins, etc., which are not listed one by one in this application.

[0056] In one embodiment of the present application, the first control motor directly drives the earphone part to move toward the inner side or the outer side of the side end part, or the first control motor indirectly drives the earphone part to move toward the inner side or the outer side of the side end part through the fixing plate.

[0057] In this embodiment, the first control motor controls and drives the earphone part to move to the inner side or outer side of the side end part. As for the specific mechanical connection relationship between the first control motor, the fixing plate and the earphone part, it can be arbitrarily and flexibly set according to the conventional technical means and basic common sense in the field. The protection scope of this application is not limited to the mechanical connection structure between the first control motor, the fixing plate and the earphone part listed in this specific implementation. Any connection relationship design based on the technical principle of this application combined with the existing technical means is included in the protection scope of this application.

[0058] In one embodiment of the present application, the second control motor directly drives the earphone portion to move forward or backward of the side end portion, or the second control motor indirectly drives the earphone portion to move forward or backward of the side end portion through the fixing plate.

[0059] In this embodiment, the second control motor controls and drives the earphone part to move forward or backward of the side end. As for the specific mechanical connection relationship between the second control motor, the fixing plate and the earphone part, it can be arbitrarily and flexibly set according to the conventional technical means and basic common sense in the field. The protection scope of this application is not limited to the mechanical connection structure between the second control motor, the fixing plate and the earphone part listed in this specific implementation. Any connection relationship design based on the technical principle of this application combined with the existing technical means is included in the protection scope of this application.

[0060] In the specific implementation of the present application, the first control motor and the second control motor are respectively used to directly drive the earphone part to move, or to indirectly drive the earphone part to move, and can be flexibly combined and arranged according to actual needs. The protection scope of the present application is not limited to the combination design of direct drive and indirect drive, and the combination embodiments of direct drive and indirect drive are no longer listed one by one. Any combination of direct drive and indirect drive that can be realized according to the technical principle of the present application combined with the existing technical means can be included in the protection scope of the present application.

[0061] like Figure 4 As shown, in one embodiment of the present application, the side end 122 of the headband portion 120 includes a second rear end portion 124 extending therefrom; the earphone portion 130 is matched and connected to the front end of the second rear end portion 124. This embodiment provides a second structural implementation scheme of the headband portion, and the protection scope of the present application is not limited to the two schemes illustrated in the present specific implementation scheme, and all existing technical extension and deformation schemes made according to the design principle of the present application are included in the protection scope of the present application.

[0062] like Figure 5As shown, in one embodiment of the present application, the earphone part 130 includes an earphone main component 131 and an earphone connector 132; one end of the earphone connector 132 is movably connected to the side end portion, and the other end of the earphone connector 132 is fixedly connected to the earphone main component 131.

[0063] like Fig. 6A As shown, the earphone connector 132 moves toward the inside or outside of the side end portion through the movable connection point a with the side end portion; or / and the earphone portion moves toward the front or back of the side end portion through the movable connection point a with the side end portion.

[0064] Specifically, in this embodiment, one end of the earphone connector is movably connected to the side end portion, and the movable connection mode of the first connection point enables the earphone portion to move toward the inside or outside of the side end portion around the movable connection point, or enables the earphone portion to move toward the front or back of the side end portion around the movable connection point.

[0065] like Figure 6B As shown, in another embodiment of the present application, the earphone part 130 includes an earphone main component 131 and an earphone connector 132; one end of the earphone connector 132 is fixedly connected to the side end portion 122, and the other end of the earphone connector 132 is movably connected to the earphone main component 131; the earphone main component moves toward the inside or outside of the side end portion through the active connection point b with the earphone connector; or / and the earphone main component moves toward the front or back of the side end portion through the active connection point b with the earphone connector.

[0066] Specifically, in this embodiment, one end of the earphone connector is fixedly connected to the side end portion. At this time, the first connection point cannot move in any direction. Then, the other end of the earphone connector can be movably connected to the earphone main component, so that the movable connection mode of the second connection point can realize the movement of the earphone part around the movable connection point toward the inside or outside of the side end portion, or realize the movement of the earphone part around the movable connection point toward the front or back of the side end portion.

[0067] like Fig. 6A and Figure 6B As shown, further, the earphone part 130 includes an earphone main component 131 and an earphone connector 132; the earphone connector 132 is an elastic component with a bending arc, and the elastic component is used to apply a first elastic force to the earphone main component to move the earphone main component toward the inside or outside of the side end portion; or / and the elastic component is used to apply a second elastic force to the earphone main component to move the earphone main component toward the front or back of the side end portion.

[0068] like Fig. 6A and Figure 6BAs shown, further, the bending arc of the headphone connector 132 has an angle range of 35 to 45 degrees, which refers to the angle α range of the headphone connector relative to a vertical plane (a plane perpendicular to the ground). The bending arc of 35 to 45 degrees is a relatively comfortable angle range for wearing.

[0069] Specifically, the inward and outward movement or the forward and backward movement in this embodiment is not achieved through the first connection point or the second connection point, but is achieved through the elastic characteristics of the earphone connector. Because the earphone connector is an elastic member with a bending arc, the elastic member can apply a first elastic force (i.e., an elastic force in a first direction) to the earphone main member to move the earphone main member to the inside or outside of the side end; of course, the elastic member can also apply a second elastic force (i.e., an elastic force in a second direction) to the earphone main member to move the earphone main member to the front or back of the side end.

[0070] like Fig. 7A As shown, in one embodiment of the present application, the outer layer structure of the side end portion 122 of the headband portion is a first fixed structure; the earphone portion 130 is matched and connected with the first fixed structure. The first fixed structure and the side end portion of the headband portion are an integrated structure, and the earphone portion moves to the inside or outside of the side end portion through the connection point with the first fixed structure.

[0071] Furthermore, when the earphone connector is a spring sheet with a bending arc, it will be more comfortable to wear.

[0072] Specifically, the spring piece can be a straight leaf spring (a spring piece with a straight line shape), a bent leaf spring (a spring piece with a curved shape), a rectangular spring piece (rectangular or square, commonly used to connect and fix components), a trapezoidal spring piece (trapezoidal in shape, with a specific load-bearing capacity), a triangular spring piece (triangular in shape, used for connection and fixation in specific occasions), a stage-shaped spring piece (a spring piece with a staged structure), etc.

[0073] The shrapnel can also be a pressure-bearing shrapnel (maintaining elasticity under high pressure to ensure sealing performance), a shock-absorbing shrapnel (reducing vibration and noise of a machine or equipment through the principle of elastic vibration reduction), a conductive shrapnel (having conductivity, used in electronic equipment to maintain equipment stability and reduce circuit noise), a heat-insulating shrapnel (having good insulation performance, used to prevent heat from damaging the equipment), a waterproof shrapnel (having sealing and waterproof properties, used to prevent water penetration and leakage), etc.

[0074] The shrapnel can also be a stainless steel shrapnel, a memory titanium alloy shrapnel (made of stainless steel, memory titanium alloy materials, with corrosion resistance and good mechanical properties), a carbon steel shrapnel (made of carbon steel material, with good strength and durability), or a copper shrapnel (made of copper material, with good electrical conductivity), an aluminum shrapnel (made of aluminum alloy, with light weight and good strength) and other metal shrapnel.

[0075] The shrapnel may also be a ceramic shrapnel (having extremely high hardness and wear resistance), a composite material shrapnel (composed of a combination of multiple materials, such as a composite of carbon fiber and resin), etc.

[0076] Specifically, if the outer layer structure of the side end portion of the headband portion is a solid structure and can achieve a fixing function, the earphone portion can be directly matched and fixed to the outer layer structure without adding other fixing structures.

[0077] like Figure 7B As shown, in one embodiment of the present application, a first fixing structure 150 is disposed in the side end portion 122 of the headband portion 120 ; the earphone portion 130 is matched and connected to the first fixing structure 150 .

[0078] Specifically, if the outer layer structure of the side end portion of the headband portion is not a solid structure and cannot achieve the fixing function, a first fixing structure may be provided embedded in the side end portion of the headband portion to achieve a matching connection with the earphone portion.

[0079] like Figure 7C As shown, in one embodiment of the present application, the first fixing structure 150 includes a fixing plate 151 and a fixing member 152; the fixing plate 151 clamps the earphone part 130, and locks the fixing plate and the earphone part through the fixing member 152; the earphone part 130 moves toward the front or rear of the side end portion through the locking point c with the fixing member 152.

[0080] Furthermore, the fixing member is a screw, and the fixing plate and the earphone part are fixed by the screw.

[0081] like Figure 7C As shown, specifically, in this embodiment, the function of the earphone part moving forward or backward toward the side end is realized by the fixing plate 151 and the fixing member 152. The fixing plate 151 can also clamp the earphone part 130 through the buffer structure 153, so that the earphone part has appropriate resistance when moving forward and backward, and can move under thrust, and can also stop when thrust is lost.

[0082] Specifically, in this embodiment, the fixing plate can be implemented by a plastic sheet, and the earphone connector can be fixed by the fixed plastic sheet, which is not only convenient for fixation, but also a silicone ring (i.e., a buffer structure) can be set in the fixed plastic sheet to generate friction and buffer the fixing pressure.

[0083] like Fig.7D As shown, in one embodiment of the present application, the first fixing structure 160 includes a fixing plate 161, a first control motor 162 and a second control motor 163; the first control motor 162 is mechanically connected to the fixing plate 161, driving the fixing plate to move toward the inside or outside of the side end, thereby driving the earphone part to move toward the inside or outside of the side end. The second control motor 163 is fixed to the fixing plate 161 and mechanically connected to the earphone part 130, driving the earphone part to move toward the front or rear of the side end.

[0084] Specifically, in this embodiment, the first control motor is used to achieve inward and outward movement of the earphone part in a first direction, and the second control motor is used to achieve forward and backward movement of the earphone part in a second direction, thereby achieving automatic adaptive position adjustment of the earphone part without human intervention.

[0085] like Fig. 8A As shown, in one embodiment of the present application, a pressure sensor 133 is provided on the main side of the earphone part 130, and the pressure sensor 133 is configured to collect fitting information of the earphone part when worn (force information or pressure information showing tightness); the host outputs a movement control instruction based on the fitting information, controls the first control motor to drive the earphone part to move toward the inside or outside of the side end part, or controls the second control motor to drive the earphone part to move toward the front or back of the side end part.

[0086] like Fig. 8A As shown, further, a pressure sensor 133 is provided on the main side of the earphone part, and the pressure sensor 133 may include a front-to-back wearing detection pressure sensor, an upper-lower wearing detection pressure sensor, or / and an additional precision pressure sensor. The front-to-back wearing detection pressure sensor is used to detect whether the position of the earphone part worn by the subject is forward or backward. The upper-lower wearing detection pressure sensor is used to detect whether the position of the earphone part worn by the subject is upward or downward. The additional precision pressure sensor is used to detect how much the position of the earphone part worn by the subject differs from the preset standard wearing position.

[0087] For example: the pressure sensor can be any one of a resistive pressure sensor, a capacitive pressure sensor, a photoelectric pressure sensor, and an electromagnetic pressure sensor, used alone or in combination. The protection scope of the present application is not limited to the types of pressure sensors listed in this embodiment. Resistive pressure sensors use resistance strain gauges to measure pressure changes. Capacitive pressure sensors use capacitance changes to measure pressure changes. Piezoelectric pressure sensors use the piezoelectric effect to measure pressure changes. Photoelectric pressure sensors use changes in the optical properties of photoelectrics to measure pressure changes. Electromagnetic pressure sensors include inductive pressure sensors, Hall pressure sensors, eddy current pressure sensors, etc., which use electromagnetic principles for measurement.

[0088] like Fig. 8A and Figure 8B As shown, the pressure sensors Y1 and Y2 arranged on the vertical midline of the main side of the earphone part are upper and lower wearing detection pressure sensors, and the pressure sensors X1 and X2 arranged on the horizontal midline of the main side are front and back wearing detection pressure sensors. In addition, other pressure sensors Z1, Z2, Z3, Z4, etc. are all additional precision pressure sensors.

[0089] The upper and lower pressure difference values ​​detected by the pressure sensors Y1 and Y2 are compared with the preset upper and lower standard deviation values ​​to obtain a second comparison result, and an inward and outward movement control signal is generated to the first control motor based on the second comparison result. The first control motor drives and controls the earphone part to move inward and outward to the preset standard position.

[0090] The front and rear pressure difference detected by the pressure sensors X1 and X2 is compared with the preset front and rear standard difference to obtain a first comparison result, and a forward and backward movement control signal is generated to the second control motor based on the first comparison result. The earphone part is driven and controlled to move forward and backward to the preset standard position by the second control motor.

[0091] The pressure values ​​detected by the pressure sensors Z1, Z2, Z3, and Z4 are used to determine the difference between the earphone and the preset standard position, and a precision adjustment signal is generated according to the difference to control the stepping precision of the first control motor and the second control motor. Figure 8B shown.

[0092] like Fig. 9 As shown, in one embodiment of the present application, the earphone main component 131 of the earphone part 130 includes a bone conduction vibrator 1311 and a vibrator housing 1312; the bone conduction vibrator 1311 is built into the vibrator housing 1312 and is at a preset distance D from the vibrator housing.

[0093] Furthermore, in this embodiment, the preset distance between the bone conduction vibrator and the vibrator housing is most appropriately 0.38-0.65 mm. If the preset distance is less than 0.38 mm, the vibration transmission efficiency of the earphone will be reduced, affecting the sound transmission effect and increasing the sound leakage problem of the earphone, because the vibration is more easily transmitted to the housing, thereby generating unnecessary sound leakage, limiting the free vibration of the vibration unit, and thus affecting the sound quality, especially in terms of low-frequency response. If the preset distance is greater than 0.65 mm, the structural stability of the earphone will be reduced, affecting the stability of wearing, reducing the effective force of the vibration unit on the skull, reducing the efficiency and sound quality of sound transmission, and there is a risk of sound quality decay, which will reduce the wearing comfort of the earphone because a larger clamping force is required to keep the earphone stable.

[0094] like Fig. 10A As shown, in one embodiment of the present application, the host 110 is electrically connected to the earphone part 130 through a flexible circuit board; the flexible circuit board is built into the headband part 120; and the flexible circuit board is in a curved shape.

[0095] Specifically, the present embodiment uses a flexible circuit board to realize the electrical connection between the earphone part and the host, which can not only realize communication and power supply, but also can deform with the headband part due to its flexibility without affecting its own functions. In addition, the flexible circuit board is designed in a curved shape to increase the stretch margin of the flexible circuit board, which is more suitable for the telescopic wearing requirements of the headband part.

[0096] like Fig. 10B As shown, for example: the flexible circuit board 170 has a plurality of electrical connection points, including connection points A1 and A2 configured to be electrically connected to two earphone parts respectively, connection points B1, B2, B3, B4, B5, B6 configured to be electrically connected to six electrodes respectively, and connection point C configured to be electrically connected to an interface. The interface is an interface that can realize data transmission and power supply at the same time, such as a Pogopin interface.

[0099] Specifically, the working principle of the photoplethysmography sensor is based on optical absorption and spectral analysis. It uses two light sources with different wavelengths - usually red light (wavelength of about 660 nanometers) and infrared light (wavelength of about 940 nanometers). These light sources emit light through the light-emitting diodes (LEDs) on the sensor, passing through the fingertips, earlobes or other thin, blood vessel-rich parts. On the other side of the sensor, there is a photodetector that receives the light that has passed through the tissue. Due to the different light absorption characteristics of oxygenated hemoglobin (HbO2) and reduced hemoglobin (Hb), the sensor can calculate the blood oxygen saturation based on the changes in the intensity of the received light of different wavelengths.

[0100] In addition to the photoplethysmography sensor, the intelligent sleep aid device described in this embodiment can also be provided with other types of sensors according to actual needs. The protection scope of this application is not limited to the types and quantities of sensors listed in this embodiment.

At least one function button 110h is disposed on the second side surface 110e or the fourth side surface 110f of the host, and the function button 110h is electrically connected to the host 110 via a flexible circuit board.

[0103] Furthermore, the function keys include a power key, a volume adjustment key, or other types of function keys.

[0105] It should be noted that the space formed by the battery rack and the main shell serves as an independent battery compartment, and the battery compartment formed by the battery rack can protect the battery, and the battery rack can also serve as a supporting structure to support the main circuit board placed above. The photoplethysmography sensor can be arranged below the battery.

[0106] like Fig. 12C As shown, in one embodiment of the present application, the main circuit board assembly 114 includes a main circuit board 1141 and an audio driver board 1142; the main circuit board and the audio driver board are rigid circuit boards, which are connected by a flexible circuit board communication and can adapt to the space size of the host. The main circuit board assembly is internally connected by a flexible circuit board communication, eliminating the connector, saving space, and the connection stability is also relatively high.

[0107] Specifically, the audio driving board can be supported by supporting columns in the housing of the host and can be installed obliquely in the housing of the host to maximize the use of the space in the housing.

[0108] In one embodiment of the present application, a plurality of raised electrode portions are provided on the bottom surface of the host, and an electrode through hole is provided at a position corresponding to the electrode portion at the front end portion of the headband portion, and the electrode portion passes through the electrode through hole to touch the head of the subject to collect EEG signals, and the electrode portion is electrically connected to the host.

[0109] like Fig.13 As shown, in one embodiment of the present application, the electrode part 180 is made of a conductive cloth 181; the middle part of the conductive cloth 181 is supported by a conductive fixing structure 182 and an elastic buffer structure 183 to form an electrode convex part, and the peripheral part of the conductive cloth is fixed to the front end of the headband part through the conductive fixing structure 182; the electrode convex part protrudes from the inner side of the front end of the headband part through the corresponding electrode through hole; the conductive cloth 181 is connected to the host through the conductive fixing structure 182.
