Description

Technical Field

[0001] This utility model relates to the field of headphone equipment technology, and more specifically, to a headphone device with an in-ear health monitoring function. Background Technology

[0002] With their superior sound quality, headphones have become an indispensable accessory for entertainment and audio-visual equipment. Currently, over-ear headphones consist of a headband and two earpieces, which are connected to the two ends of the headband. When worn, the two earpieces cover the user's ears. At the same time, the earpieces contain sound-producing units to enable their listening function. Headphones with in-ear health monitoring functions are smart wearable products that integrate biosensor technology and audio equipment. They aim to provide users with health data feedback by monitoring physiological indicators in the ear canal in real time, thereby preventing hearing damage.

[0003] Current headphones are worn behind the head, and because the headband only has a simple telescopic function, the headphone position is easily shifted when the user's head shakes or when worn for too long, thus affecting the use. Moreover, when headphones are worn for too long, the ears will sweat due to lack of ventilation, which not only affects the user's comfort, but also causes contamination of the headphone device because it is not easy to clean. Utility Model Content

[0004] The purpose of this invention is to address the problems of existing headphone devices that are prone to shifting during prolonged wear, affecting usability, and the problem of users' ears sweating, affecting comfort.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] An earphone device with in-ear health monitoring function includes a headband and sound-generating components disposed on both sides of the headband. The headband includes a wearing cover and two symmetrically sliding arc plates inside the wearing cover. The sound-generating components include an earpiece portion disposed at the bottom of the arc plates and a sealing sleeve sleeved outside the earpiece portion. The device also includes:

[0007] A shrinking assembly, which is disposed inside the wearing sleeve, is used to pull two arc plates to slide inward into the wearing sleeve to shorten the distance between the two earpiece parts;

[0008] And a positioning component, which is disposed on the outside of the wearing cover to increase the contact area between the wearing cover and the user's head.

[0009] As a preferred technical solution of this application, the shrinking component includes a partition disposed in the middle section inside the wearing sleeve, a slider slidably disposed on the inner wall of the wearing sleeve, and springs disposed at both ends of the slider and between the arc plate and the partition.

[0010] As a preferred technical solution of this application, the positioning component includes an installation sleeve fitted over the outside of the wearing sleeve, a pressure pad disposed on the side wall of the installation sleeve, and a first bolt threaded onto the top of the installation sleeve, wherein the top of the wearing sleeve has a screw hole that mates with the first bolt.

[0011] As a preferred technical solution of this application, the sealing sleeve has a flow cavity inside, the inner wall of the sealing sleeve has a plurality of air outlet holes communicating with the flow cavity, and the outer wall of the sealing sleeve has a plurality of air inlet holes communicating with the flow cavity.

[0012] As a preferred technical solution of this application, an adjustment assembly is provided between the arc plate and the earpiece. The adjustment assembly includes an arc-shaped frame disposed at the bottom of the arc plate, a movable shaft disposed on the inner walls of both ends of the arc frame, and a movable groove formed on the side walls of both ends of the earpiece and cooperating with the movable shaft.

[0013] As a preferred technical solution of this application, both the outer wall of the movable shaft and the inner wall of the movable groove are provided with mutually cooperating anti-slip textures.

[0014] As a preferred technical solution of this application, a fixing sleeve is provided on the top of the arc frame, a limiting post is inserted into the side wall of the fixing sleeve, a second bolt is threaded to one end of the limiting post, and a positioning hole that cooperates with the limiting post is opened on the outer wall of the arc plate near the bottom.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. When the user needs to wear the headphones, the sound-generating component is placed on the head via the headband. At this time, the retraction component allows the two arc plates to retract into the wearing cover, thereby causing the two earpieces to press tightly against the user's ears. In addition, the positioning component increases the contact area between the wearing cover and the patient's head, thereby improving the stability of the headphones and solving the problem in the prior art where headphones would shift due to head shaking when worn for a long time, affecting usability.

[0017] 2. The sealing sleeve improves the seal between the user's ear and the earpiece, thereby improving sound quality. Furthermore, the flow chamber, vent, and air inlet inside the sealing sleeve allow for ventilation of the ear, preventing sweating caused by prolonged sealing. This not only improves user comfort but also prevents sweat from contaminating the headphone device. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0028] like Figures 1 to 5 As shown, this embodiment proposes an earphone device with in-ear health monitoring function, including a headband 1 and sound-generating components 2 disposed on both sides of the headband 1, as well as a shrinking component 3 and a positioning component 4. The headband 1 includes a wearing cover 101 and two symmetrically sliding arc plates 102 inside the wearing cover 101. The sound-generating component 2 includes a earpiece portion 201 disposed at the bottom of the arc plate 102 and a sealing sleeve 202 sleeved on the outside of the earpiece portion 201. The shrinking component 3 is disposed inside the wearing cover 101 and is used to pull the two arc plates 102 to slide inward into the wearing cover 101 to shorten the distance between the two earpiece portions 201. The positioning component 4 is disposed outside the wearing cover 101 and is used to increase the contact area between the wearing cover 101 and the user's head.

[0029] When using the headphone device, the user first puts the sound-generating component 2 on their head through the headband 1. The retraction component 3 pulls the two arc plates 102 to slide into the wearing sleeve 101, so that the two earpieces 201 can be tightly pressed against the user's ears, which can improve the stability of the headphones and prevent the headphones from shifting due to head shaking during prolonged wear, thus affecting their use. In addition, the positioning component 4 can increase the contact area between the wearing sleeve 101 and the user's head, so that the headband 1 can be worn more stably on the head, further improving the stability of the headphones. The sealing sleeve 202 can improve the sealing between the earpieces 201 and the ears, preventing sound leakage and thus improving the sound quality of the headphones.

[0030] It should be noted that earphones with in-ear health monitoring capabilities are smart wearable products that integrate biosensor technology and audio equipment. They aim to provide users with health data feedback by monitoring physiological indicators within the ear canal in real time. The following are the key technical features and functional designs of this type of device:

[0031] I. Core Monitoring Functions:

[0032] Body temperature monitoring; integrates high-precision infrared or thermopile sensors to detect ear canal temperature and tympanic membrane temperature in real time, which is close to the core body temperature and is suitable for fever early warning.

[0033] Heart rate and PPG; monitors blood flow changes through an LED photoelectric sensor and photosensitive element in the ear canal, and calculates heart rate and blood oxygen saturation (SpO2), suitable for sports and health monitoring.

[0034] Hearing health analysis; the microphone captures changes in the ear canal's resonant frequency, combined with environmental noise detection, to assess the risk of hearing damage, such as warnings of prolonged exposure to high decibels.

[0035] Ear environment detection; humidity / pressure sensor monitors ear canal moisture levels to prevent otitis media or eczema; some high-end models may support earwax buildup alerts.

[0036] II. Technical Implementation Solution:

[0037] Multimodal sensor fusion; miniaturized sensor arrays such as AMS' AS7038RB biosensor are integrated into the earphone cavity, and signal interference issues such as active noise cancellation and PPG signal co-processing need to be addressed.

[0038] Low-power Bluetooth transmission; uses BLE 5.3 protocol to synchronize data to mobile APP, and supports offline storage such as Nordic Semiconductor chip solutions.

[0039] AI health algorithms; machine learning models such as LSTM neural networks analyze long-term trends and identify abnormal patterns such as arrhythmia or sudden increase in body temperature.

[0040] The sealing sleeve 202 has a flow cavity inside, and several air outlets 2021 connected to the flow cavity are opened on the inner wall of the sealing sleeve 202. Several air inlets 2022 connected to the flow cavity are opened on the outer wall of the sealing sleeve 202. Through the flow cavity, air outlets 2021 and air inlets 2022, the inside of the sealing sleeve 202 can be connected to the outside air, so as to complete the ventilation of the ear and prevent the ear from sweating due to being sealed for a long time. This not only improves the user's comfort, but also prevents sweat from contaminating the headphone device.

[0041] Specifically, such as Figure 1 , Figure 3 and Figure 7 As shown, in a preferred embodiment, based on the above method, the shrinking component 3 further includes a partition 303 disposed in the middle section inside the wearing sleeve 101, a slider 301 slidably disposed on the inner wall of the wearing sleeve 101, and a spring 302 disposed between the two ends of the slider 301 and the arc plate 102 and the partition 303.

[0042] The spring 302 automatically pulls the two arc plates 102 towards the inside of the wearing cover 101 under normal conditions. The slider 301 reduces the length of the spring 302, preventing it from bending inside the arc-shaped wearing cover 101 due to excessive length. This improves the stability of the arc plates 102. When wearing the headphones, first pull the arc plates 102 to the sides to put the wearing cover 101 on the head, and then release the arc plates 102. At this time, the spring 302 is released and causes the arc plates 102 to rebound and reset. This causes the earpiece part 201 at the bottom of the arc plate 102 to press firmly against the user's ear, thus improving the stability of the headphones.

[0043] In addition, such as Figure 1 , Figure 3 and Figure 6 As shown, in a preferred embodiment, based on the above method, the positioning component 4 further includes an installation sleeve 401 sleeved on the outside of the wearing sleeve 101, a pressure pad 402 disposed on the side wall of the installation sleeve 401, and a first bolt 403 threaded on the top of the installation sleeve 401. The top of the wearing sleeve 101 is provided with a screw hole that cooperates with the first bolt 403.

[0044] Before wearing the headphones, the mounting sleeve 401 can be inserted into the outside of the wearing sleeve 101, and then the first bolt 403 can be screwed into the screw hole at the top of the wearing sleeve 101 through the mounting sleeve 401 to fix the mounting sleeve 401 and the pressure pad 402. Therefore, after the wearing sleeve 101 is worn on the user's head, the pressure pad 402 will also abut against the user's head, thereby increasing the contact area between the wearing sleeve 101 and the user's head and further preventing the wearing sleeve 101 from shifting on the user's head.

[0045] like Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, an adjustment component 5 is further provided between the arc plate 102 and the earpiece part 201. The adjustment component 5 includes an arc-shaped frame 501 provided at the bottom of the arc plate 102, a movable shaft 502 provided on the inner walls of both ends of the arc-shaped frame 501, and a movable groove 503 provided on the side walls of both ends of the earpiece part 201 and cooperating with the movable shaft 502. The outer wall of the movable shaft 502 and the inner wall of the movable groove 503 are provided with mutually cooperating anti-slip textures.

[0046] Because the movable shaft 502 is rotatably mounted in the movable groove 503, the earpiece 201 can rotate inside the arc frame 501, allowing for fine-tuning of the earpiece 201's angle. This improves the earphone's adaptability and makes it easier for more people to use. The anti-slip texture increases the friction between the movable shaft 502 and the movable groove 503, so the earpiece 201 can only be adjusted by manually rotating it. When the earpiece 201 stops rotating, it will automatically stop rotating without external force, facilitating quick positioning of the adjusted earpiece 201.

[0047] It is worth mentioning that a fixing sleeve 6 is provided on the top of the arc frame 501, and a limiting post 601 is inserted into the side wall of the fixing sleeve 6. A second bolt 602 is threaded to one end of the limiting post 601. The outer wall of the arc plate 102 near the bottom is provided with a positioning hole that cooperates with the limiting post 601. When the headphone device is not in use, the second bolt 602 can be rotated to remove the limiting post 601, and then the limiting post 601 can be pulled out from between the fixing sleeve 6 and the arc plate 102. This allows the arc plate 102 to be pulled out from the fixing sleeve 6, which facilitates the disassembly of the headband 1 and the sound-generating component 2, and facilitates the storage of the device, preventing the headphone device from being damaged by pressure during storage due to its large size.

[0048] The working principle of this utility model is as follows: When using the earphone device, the user first pulls the arc plate 102 to both sides to put the wearing cover 101 on their head, and then releases the arc plate 102. At this time, the spring 302 is released from its force, causing the arc plate 102 to rebound and return to its original position. This allows the earpiece part 201 at the bottom of the arc plate 102 to press firmly against the user's ear, which can improve the stability of the earphone and prevent the earphone from shifting due to head shaking during prolonged wear, thus affecting its use. Moreover, after the wearing cover 101 is put on the user's head, the pressure pad 402 will also press against the user's head, thereby increasing the contact area between the wearing cover 101 and the user's head, further preventing the wearing cover 101 from shifting on the user's head. In addition, the sealing sleeve 202 can improve the seal between the earpiece 201 and the ear, prevent sound leakage, and thus improve the sound quality of the headphones. At the same time, the flow cavity, vent 2021 and vent 2022 can connect the inside of the sealing sleeve 202 with the outside air, complete the ventilation of the ear, and prevent the ear from sweating due to being sealed for a long time. This not only improves the user's comfort, but also prevents sweat from contaminating the headphone device.

[0049] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
