Description

Technical Field

[0001] This invention relates to the field of sports headphone technology, and in particular to a smart over-ear sports headphone. Background Technology

[0002] Over-ear sports headphones offer an immersive audio experience and excellent physical noise isolation. Compared to in-ear headphones, they typically have a wider soundstage and superior sound quality. Furthermore, because they don't penetrate deep into the ear canal, they reduce discomfort that may occur during prolonged wear, making them popular among some sports enthusiasts.

[0003] However, existing over-ear sports headphones still have a significant drawback in practical use: insufficient stability during vigorous exercise. When users engage in high-intensity or high-impact activities such as basketball or jumping, the body experiences violent and irregular shaking and impact. Traditional over-ear headphones primarily rely on the clamping force of the headband and the static wrapping of the earcups to maintain stability. This passive fixation method is ineffective in dealing with dynamic impact forces. As a result, the headphones are prone to shifting, loosening, or even slipping off, forcing users to frequently interrupt their activities to adjust the headphone position, severely disrupting the continuity of exercise and the user experience.

[0004] To address these technical issues, we propose a smart over-ear sports headphone. Summary of the Invention

[0005] This invention provides a smart over-ear sports headphone to solve the problems mentioned in the background art, such as the tendency of over-ear sports headphones to shift, loosen, or slip off during vigorous exercise.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A smart over-ear sports headphone, comprising: The headphone assembly includes a speaker unit and earcups, the earcups being mounted on the sound-emitting end of the speaker unit and used to cover the user's ear. A monitoring device is used to monitor the user's movement status. The monitoring device includes a moving body and a detection sensor. The moving body moves with the user's movement, and the detection sensor is used to detect the movement parameters of the moving body. The control unit is used to receive activity parameters and generate corresponding control signals; A scaling device, mounted on the headphone assembly, is used to drive the earcups to deform according to a control signal, thereby changing the clamping force of the earcups on the auricle.

[0007] Preferably, the earmuff has a receiving cavity for accommodating the auricle, and the edge of the earmuff has an annular clamping portion surrounding the receiving cavity, the annular clamping portion being configured to deform toward the center of the receiving cavity.

[0008] The earmuff can accommodate and cover the user's auricle through the receiving cavity, while the ring clamp can abut against the root of the auricle. When the ring clamp contracts, it can make the earmuff fit firmly on the auricle and not easily loosen.

[0009] Preferably, the scaling device includes a tensioning band and a motor, the motor being used to control the tightening or loosening of the tensioning band.

[0010] Specifically, the annular clamping part has an annular channel inside, and a tension strap is arranged inside the annular channel. At least one end of the tension strap is connected to the power output end of the motor. The motor is mounted on the speaker unit and located on one side of the earcup. An output shaft is installed on the power output end of the motor, and at least one end of the tension strap is wrapped and fixed to the output shaft.

[0011] The motor drives the output shaft to rotate, and the rotating output shaft can wind or unwind the tensioning tape. When the tensioning tape is wound, the tensioning tape pulls the annular clamping part to contract radially, thereby clamping the ear; when unwinding, the tensioning tape and the annular clamping part spring back to their original positions.

[0012] Preferably, the monitoring device further includes a guide sleeve having a rotating end and a free end, the rotating end being pivotally connected to the earphone assembly. The detection sensor is a pressure sensor, installed inside the guide sleeve and adjacent to the rotating end. The movable body is spherical, movably positioned inside the guide sleeve, and capable of reciprocating between the rotating end and the free end.

[0013] The spherical movable body can roll or displace within the guide sleeve, allowing it to move in sync with the user's movements. During this movement, the movable body impacts a pressure sensor, which detects the impact force and sends it to the control unit. The greater the user's movement, the greater the displacement of the movable body within the guide sleeve, and the greater the impact force on the pressure sensor. The control unit then determines the intensity of the movement based on the detected pressure data and accordingly controls the motor to wind or unwind the tensioning tape.

[0014] Preferably, the headphone assembly further includes a headband, two speaker units are provided and respectively located at both ends of the headband, and the rotating end of the guide sleeve is pivotally connected to the headband.

[0015] Preferably, the control unit includes a microcontroller and a power module, wherein the power module supplies power to the microcontroller, the monitoring device, and the scaling device.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: In this invention, when a user exercises while wearing headphones, the spherical movable body rolls or shifts with the user's movements, impacting a pressure sensor. The sensor then transmits the detected pressure signal to the control unit in real time. As the user's movement amplitude increases, the displacement amplitude of the movable body within the guide sleeve increases accordingly, thereby applying a greater impact force to the pressure sensor. This accurately converts physical motion parameters into electrical signals. Based on the strength of the received electrical signal, the control unit can intelligently determine the intensity of the user's movement.

[0017] Furthermore, based on the pressure data, the control unit drives the motor to wind or unwind the tension band, thereby dynamically adjusting the tightness of the annular clamp. When the user is exercising vigorously, the annular clamp automatically tightens, enhancing the wrapping and clamping force on the ear and effectively preventing the earphone from shifting or falling off; when the user's exercise slows down or stops, the annular clamp automatically relaxes, returning to a comfortable wearing position.

[0018] In summary, the present invention achieves real-time perception and intelligent response to the user's movement state through the above structure, and can automatically adjust the clamping force of the earphone according to the intensity of the exercise, which not only ensures the stability and safety of the earphone during exercise, but also takes into account the wearing comfort under normal conditions.

[0030] Please see Figures 1 to 7 : This invention provides a smart over-ear sports headphone, including a headphone assembly 100, which includes a speaker unit 101 and earcups 102. The earcups 102 are mounted on the sound-emitting end of the speaker unit 101 and are used to cover the user's auricle. A monitoring device 200 is used to monitor the user's movement state. The monitoring device 200 includes a moving body 203 and a detection sensor 202. The moving body 203 moves with the user's movement, and the detection sensor 202 is used to detect the movement parameters of the moving body 203. A control unit 300 is used to receive the movement parameters and generate corresponding control signals. A scaling device 400 is used to drive the earcups 102 to deform according to the control signals, so as to change the clamping force of the earcups 102 on the auricle.

[0031] like Figures 1 to 5 As shown, in a preferred embodiment, a control unit 300 is mounted on the headphone assembly 100. The control unit 300 includes a microcontroller and a power module, the power module supplying power to the microcontroller, the monitoring device 200, and the scaling device 400. The headphone assembly 100 also includes a headband 103, with two speaker units 101 respectively located at both ends of the headband 103, and a guide sleeve 201 pivotally connected to the headband 103. The earcups 102 have receiving cavities 1021 for accommodating the auricle, and the edge of the earcups 102 has an annular clamping portion 1022 surrounding the receiving cavity 1021, the annular clamping portion 1022 being configured to deform toward the center of the receiving cavity 1021.

[0032] When a user wears the headphones, their auricle is accommodated within the receiving cavity 1021 of the earcup 102. The annular clamping part 1022 fits circumferentially against the root of the auricle. When the tightening device drives the annular clamping part 1022 to contract radially, it increases the contact pressure and coverage area with the root of the auricle, thereby significantly enhancing the adhesion between the earcup 102 and the user's head and effectively preventing loosening or slippage during vigorous exercise.

[0033] In this embodiment, a speaker (not shown in the figure) is provided inside the speaker unit 101. A sound outlet is provided between the receiving cavity 1021 of the earcup 102 and the sound outlet end of the speaker unit 101, thereby ensuring that the sound generated by the speaker can be effectively transmitted into the receiving cavity 1021 and perceived by the user. The earcup 102 is preferably made of memory foam material, which not only has good wearing comfort and fit, but also has good deformation recovery ability. When the annular clamping part 1022 deforms due to adjustment operation, the earcup 102 can automatically return to its original shape after the external force is removed, thereby always maintaining a stable sealing structure and a comfortable wearing state.

[0034] In this embodiment, the headband 103 adopts a three-section telescopic adjustment structure, mainly including a central main section and two symmetrically arranged side telescopic sections. The two side telescopic sections are connected to the main section through sliding pairs. Users can adjust the extension length of the two side telescopic sections by sliding, thereby adjusting the overall clamping diameter of the headband 103 to flexibly adapt to different users' head circumference and head shape characteristics. This structure is further provided with an adjustment positioning mechanism (not shown in the figure), such as a ratchet structure, spring pin positioning, or friction damping positioning, which can reliably maintain the required length after adjustment, preventing the headband 103 from accidentally loosening or slipping due to movement or external force during use. In this way, not only is the wearing adaptability and comfort of the headphones significantly improved, but it also helps to ensure that the speaker unit 101 is always stably aligned with the auricle, maintaining good acoustic performance.

[0035] like Figure 3 As shown, in a preferred embodiment, the scaling device 400 includes a tension band 401 and a motor 402, the motor 402 being used to control the tightening or loosening of the tension band 401. An annular clamping portion 1022 has an annular channel 1023 inside, and the tension band 401 is arranged within the annular channel 1023, with at least one end of the tension band 401 connected to the power output end of the motor 402. The motor 402 is mounted on the speaker unit 101 and located on one side of the earcup 102. An output shaft 4021 is mounted on the power output end of the motor 402, and at least one end of the tension band 401 is wound and fixed to the output shaft 4021.

[0036] In this embodiment, both the tightening band 401 and the annular clamping part 1022 are made of elastic material, possessing excellent elastic deformation capability. One end of the tightening band 401 is fixed to the output shaft 4021 of the motor 402, and the other end is connected to the inside of the earcup 102. The microcontroller can automatically control the operation of the motor 402 based on the motion status signal. When the motor 402 rotates, it drives the output shaft 4021 to rotate. When the output shaft 4021 rotates in the forward direction, it performs a winding operation on the tightening band 401, gradually pulling out the tightening band 401 that was originally located in the annular channel 1023. This action causes the annular clamping part 1022 to elastically contract and deform towards the center of the receiving cavity 1021, thereby increasing the wrapping force on the auricle, ensuring that the earcup 102 fits firmly against the ear, and effectively preventing the earcup 102 from loosening during movement. When the output shaft 4021 rotates in the reverse direction, the tension of the tension band 401 is released, the annular clamping part 1022 rebounds and resets under its own elasticity, the tension band 401 also loosens and retracts back into the annular channel 1023, and the earcups 102 return to a natural wearing state.

[0037] In another embodiment (not shown in the figure), both ends of the tension band 401 can extend from inside the earmuff 102 and are fixed to the output shaft 4021 of the motor 402 in a symmetrical arrangement. When the output shaft 4021 rotates, the two ends of the tension band 401 can be wound or unwound simultaneously, forming bidirectional traction. This symmetrical traction method can significantly improve the transmission efficiency of the tension band 401: on the one hand, the bidirectional synchronous action makes the tension band 401 more evenly stressed during the contraction process, avoiding the skewness or jamming problems that may occur with unilateral traction, thereby accelerating the overall contraction and release speed; on the other hand, the double-end winding can increase the actual effective contraction stroke to a greater extent, so that the annular clamping part 1022 generates a larger radial contraction deformation per unit time, thereby achieving a more significant and uniform clamping force on the auricle.

[0038] like Figures 1 to 2 , Figures 6 to 7 As shown, in a preferred embodiment, the monitoring device 200 further includes a guide sleeve 201, which has a rotating end 2011 and a free end 2012. The rotating end 2011 is pivotally connected to the head beam 103. The detection sensor 202 is a pressure sensor 204, which is installed inside the guide sleeve 201 and adjacent to the rotating end 2011. The movable body 203 is spherical and is movably disposed inside the guide sleeve 201, and can reciprocate between the rotating end 2011 and the free end 2012.

[0039] In this embodiment, the guide sleeve 201 is inclined upward. The guide sleeve 201 is pivotally connected to the head beam 103 via a rotating mechanism with angle self-locking function, such as a damping hinge or a friction hinge. In this way, the user can push the free end 2012 of the guide sleeve 201 to rotate it around the hinge axis and achieve stable hovering at any angle.

[0040] In this embodiment, the movable body 203 can roll or displace freely inside the guide sleeve 201. When the user is in motion, the movable body 203 is displaced within the sleeve due to inertia. If its direction of movement is towards the pressure sensor 204, the movable body 203 will impact the sensor surface, thereby generating a pressure signal. The pressure sensor 204 detects the instantaneous pressure value generated by this impact event in real time and converts the collected pressure data into an electrical signal, which is then transmitted to the control unit 300.

[0041] When the headphones are worn, the user's exercise intensity is directly proportional to the displacement amplitude of the moving body 203. Taking a user's vigorous exercise such as running or continuous jumping as an example, the moving body 203 accelerates along the guide sleeve 201 towards the free end 2012 under the action of inertia. After reaching the maximum displacement, it retracts due to gravity and structural constraints, eventually impacting the pressure sensor 204 located at the end of the guide sleeve 201. According to the law of free fall in classical mechanics, the velocity of an object increases with height (time) during its fall, and its kinetic energy increases significantly with increasing velocity. Therefore, the greater the kinetic energy accumulated by the moving body 203 during its fall, the stronger the impact force on the pressure sensor 204, and the higher the pressure value detected accordingly.

[0042] When the user is not moving or is engaged in low-intensity exercise, the moving body 203 continuously applies pressure to the pressure sensor 204. The detected pressure value tends to be constant, and this constant pressure value serves as the reference value for the microcontroller. When the user begins to move, the microcontroller receives the changing pressure data in real time and compares it with the reference value. A greater difference between the two values ​​indicates a higher level of exercise intensity; conversely, a smaller difference indicates a less intense exercise.

[0043] The monitoring device 200 achieves indirect sensing of motion intensity by combining physical and mechanical principles with sensing technology. By converting the inertial motion of the moving body 203 into a measurable pressure signal, a standardized electrical signal is generated and input to the microcontroller. The microcontroller can identify the user's real-time motion state, providing reliable and continuous data for subsequent intelligent adjustment of the earcups 102.

[0044] When a user exercises while wearing the headphones, the microcontroller continuously monitors and analyzes real-time data from the pressure sensor 204 to determine the intensity of the user's exercise. If the pressure data consistently exceeds a baseline value, the microcontroller automatically activates the drive motor 402. The motor 402, via its output shaft 4021, winds up the tension strap 401, which in turn pulls the annular clamping part 1022 to radially contract, thereby increasing the clamping force of the earcups 102 on the user's ear.

[0045] Furthermore, the microcontroller has dynamic adjustment capabilities, as the user's level of movement is directly proportional to the real-time pressure value received. Therefore, the greater the pressure data, the more intense the movement, and the longer the winding stroke of the motor 402 becomes. Consequently, the deformation of the annular clamping part 1022 increases, achieving a more stable clamping of the auricle. Conversely, when the pressure data is lower, the winding force is reduced accordingly, and the clamping force is also appropriately reduced to ensure wearing comfort.

[0046] If the microcontroller detects that the pressure data remains close to the reference value for a preset time period (e.g., 3 seconds, 5 seconds, or 7 seconds), it determines that the user is in a static or low-intensity exercise state. At this time, the microcontroller controls the motor 402 to perform an unwinding operation, the tension strap 401 loosens, the annular clamp 1022 returns to its initial shape under its elastic action, and the earcups 102 automatically switch to a comfortable wearing mode, realizing intelligent adaptation to the user's state.

[0047] In this embodiment, the guide sleeve 201 can be flexibly adjusted in tilt angle via a pivot connection. This tilt angle directly affects the sensitivity of motion monitoring: when the guide sleeve 201 is horizontal, the internal moving part 203 is more likely to displace, and even a small movement by the user can cause a significant change in the detection value of the pressure sensor 204, resulting in high monitoring sensitivity; conversely, if the guide sleeve 201 is vertical, the moving part 203 requires a larger external force (such as a violent jump) to cause significant displacement, and the monitoring device 200's response to slight movements is reduced. Therefore, the user can adjust the angle of the guide sleeve 201 according to the actual usage scenario and personal needs, thereby achieving personalized adjustment of monitoring sensitivity.

[0048] In another alternative embodiment (not shown in the figure), the pivot mounting position of the guide sleeve 201 is not limited to the headband 103, and can also be flexibly set at other suitable parts of the headphone assembly 100 according to structural design and monitoring requirements. For example, the guide sleeve 201 can be directly pivotally connected to the housing of the speaker unit 101, or installed at the connection joint between the speaker unit 101 and the headband 103. By increasing the possible mounting positions of the guide sleeve 201, not only is the structural diversity of the headphones enriched, allowing users or manufacturers to choose different configurations according to actual usage scenarios and wearing preferences, but it also helps to optimize the overall center of gravity distribution and wearing balance, further improving the practicality and adaptability of the product.

[0049] In another alternative embodiment (not shown in the figure), the detection sensor 202 may not be limited to the pressure sensor 204, but may also be expanded to include a non-contact distance sensing device, such as an infrared distance sensor, a laser distance sensor, or an ultrasonic distance sensor. In this embodiment, the distance sensor is positioned appropriately within the guide sleeve 201, with its transmitting end facing the moving body 203, and continuously detects changes in the distance between itself and the surface of the moving body 203. When the user is in motion, the moving body 203 displaces within the guide sleeve 201 due to inertia, causing a dynamic change in the distance between it and the distance sensor. By acquiring this distance signal, the distance sensor can indirectly and accurately reflect the amplitude and intensity of the user's movement. This distance-based detection scheme does not rely on physical contact or impact, thus avoiding mechanical wear on the detection sensor 202 and enabling higher frequency and more continuous data sampling, thereby significantly improving the accuracy and response speed of motion state monitoring. Furthermore, this detection method has strong anti-interference capabilities against vibration interference, making it suitable for high-end sports headphones with extremely high requirements for monitoring accuracy.

[0050] In summary: In this invention, when a user exercises while wearing headphones, the spherical movable body 203 can roll or shift with the user's movements and impact the pressure sensor 204, which transmits the detected pressure signal to the control unit 300 in real time. As the user's movement amplitude increases, the displacement amplitude of the movable body 203 within the guide sleeve 201 increases accordingly, thereby applying a greater impact force to the pressure sensor 204, thus accurately converting physical motion parameters into electrical signals. Based on the received electrical signal strength, the control unit 300 can intelligently determine the intensity of the user's movement.

[0051] Furthermore, based on the pressure data, the control unit 300 drives the motor 402 to wind or unwind the tension band 401, thereby dynamically adjusting the tightness of the annular clamping part 1022. When the user is exercising vigorously, the annular clamping part 1022 automatically tightens, enhancing the wrapping and clamping force on the ear and effectively preventing the earphone from shifting or falling off; when the user's exercise slows down or stops, the annular clamping part 1022 automatically relaxes, returning to a comfortable wearing state.

[0052] The present invention achieves real-time perception and intelligent response to the user's exercise state through the above structure, and can automatically adjust the clamping force of the earphone according to the exercise intensity, which not only ensures the stability and safety of the earphone during exercise, but also takes into account the wearing comfort under normal conditions.
