Description

Technical Field

[0001] This utility model relates to the field of smart wearable device technology, specifically to a headset that integrates heart rate detection and bone conduction audio. Background Technology

[0002] With the integration of health monitoring and mobile audio technology, smart headphones are becoming increasingly popular. Currently, most headphones with heart rate monitoring functions use traditional air conduction drivers, which are sealed within the ear canal. Prolonged wear can cause discomfort, and during exercise, sweat can cause the headphones to slip off, affecting the stability of heart rate signal acquisition. While bone conduction headphones can keep the ear canal open, improving wearing comfort and environmental awareness, the challenge lies in how to stably and reliably integrate a heart rate detection module within its small ear canal, ensuring that the two operate independently without interference, while simultaneously achieving a comfortable wearing experience. Traditional headphone structures often struggle to balance comfortable clamping force, stable wearing posture, and efficient integration of multi-functional modules. Utility Model Content

[0003] To address the problems mentioned in the background section, this invention provides a device that is comfortable to wear, fits stably, effectively integrates bone conduction audio and heart rate monitoring functions, and is easy to expand with other sensing functions.

[0004] Over-ear headphones.

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

[0006] A headset integrating heart rate detection and bone conduction audio includes a headband body and two ear shell assemblies respectively connected to both ends of the headband body.

[0007] The headband is made of memory steel wire, which can adapt to different users' head shapes and provide a soft and continuous clamping force.

[0008] The ear shell assembly includes a main shell and an ear hook. The main shell is made of silicone and plastic composite molding, making the part that comes into contact with the skin soft and comfortable, while the internal structure is sturdy enough to accommodate electronic components. The main shell integrates a bone conduction vibrator as a sound-generating unit and a heart rate detection module for detecting the user's heart rate signal. The main shell is also provided with a charging and data transmission interface for charging and data transmission.

[0009] The ear hooks are made of silicone and memory steel wire composite, which can conform to the shape of the ear and provide stable three-point support together with the headband body.

[0010] Furthermore, the bone conduction oscillator and heart rate detection module are electrically connected to the main control circuit board inside the device, and the main control circuit board coordinates and controls audio playback and physiological signal acquisition.

[0011] Furthermore, the heart rate detection module is a photoelectric heart rate sensor, and its detection window is located on the side of the main shell that contacts the skin, and is flush with or slightly convex with the surface of the skin to ensure good contact with the skin during detection.

[0012] Furthermore, the memory wire has a U-shaped or arc-shaped structure in the headband body and ear hooks to better conform to the contours of the head and ears. The exterior of the memory wire headband can be covered with a soft coating or fabric made of skin-friendly material to enhance the tactile experience.

[0013] Furthermore, the surface of the main housing is provided with a dust cover that matches the charging data transmission interface to prevent dust or moisture from entering the interface.

[0014] Furthermore, the main housing is also provided with indicator light holes to allow light from the internal indicator lights to shine through and display the working status (such as charging, pairing, or heart rate monitoring).

[0015] Furthermore, the ear hook and the main shell can be integrally molded, simplifying the assembly process and improving the overall structural integrity.

[0016] Furthermore, the headset may also integrate at least one of a motion sensor (such as an accelerometer or gyroscope) and a temperature sensor to monitor motion data and body surface temperature.

[0017] Furthermore, the headset may also integrate at least one of a current sensor, an inductor sensor, and a voltage sensor to monitor the circuit's operating status and achieve intelligent power management or fault diagnosis.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. Combining comfort and stability: The headband and ear hooks are made of memory steel wire, combined with a silicone and plastic composite shell, which allows the headphones to adapt to the contours of the head and ears, providing a soft and stable wearing experience. This avoids the pressure of traditional hard headbands and the problem of them slipping off during exercise, and provides stable contact conditions for heart rate monitoring.

[0020] 2. Highly efficient integration and no interference: The bone conduction vibrator and heart rate detection module are rationally arranged within the limited space of the ear shell. The bone conduction sound generation method avoids ear canal obstruction, while the window of the heart rate detection module is in direct contact with the skin. The two work together without affecting each other, ensuring the reliability of audio quality and physiological signal acquisition.

[0021] 3. Compact structure and strong expandability: The modular design facilitates the integration of various sensors (such as motion, temperature, and electrical parameter sensors), which are managed uniformly through the main control circuit board, greatly enriching the functional application scenarios of the headphones.

[0022] 4. High practicality and durability: Detailed design features such as dust covers and indicator light holes enhance the product's practicality and lifespan. The use of composite materials ensures both comfort and structural strength. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 As shown in the figure, a headset integrating heart rate detection and bone conduction audio in this embodiment mainly includes a headband body 1 and two symmetrically arranged ear shell assemblies.

[0028] The headband 1 is made of shape memory steel wire, which can adapt to different users' head circumference sizes and provide continuous wearing clamping force.

[0029] Each earpiece assembly includes a main shell 5 and an ear hook 6. The main shell 5 is manufactured using a two-color injection molding or overmolding process with silicone and plastic, giving it a skin-friendly exterior and structural strength interior. The main shell 5 integrates the following:

[0030] Bone conduction oscillator 2 is used to conduct sound through the temporal bone, allowing users to clearly perceive ambient sounds while listening to audio.

[0031] The heart rate detection module 3 is a photoelectric heart rate sensor (PPG). Its detection window is located on the side of the main shell 5 that contacts the skin behind the ear. The window is flush with or slightly protrudes from the contact surface of the main shell to ensure close contact with the skin and improve signal acquisition quality.

[0032] The main shell 5 also includes:

[0033] Charging data interface 4 is used to charge the built-in battery and transmit data with external devices.

[0034] Indicator light hole 7 is used to display the device's working status (such as charging, connection, and monitoring status).

[0035] The ear hook 6 is made of a composite structure of silicone-coated memory steel wire, which ensures both wearing stability and good comfort. In a preferred embodiment, the ear hook 6 and the main shell 5 are manufactured using a one-piece molding process, which enhances the overall structural strength.

[0036] In a further embodiment, the main shell 5 may optionally also integrate:

[0037] Motion sensors (such as accelerometers and gyroscopes) are used to monitor the user's movement status and provide motion compensation for heart rate data;

[0038] Temperature sensor used to monitor body surface temperature;

[0039] At least one of a current sensor, an inductive sensor, and a voltage sensor is used to acquire electrophysiological signals such as electrocardiogram and electromyography.

[0040] All these electronic components (bone conduction vibrator 2, heart rate detection module 3, and various optional sensors) are electrically connected to the main control circuit board inside the device, which handles data processing, storage, and transmission. Working principle: After the user wears the device, the bone conduction vibrator 2 transmits audio signals through the bones to the inner ear; simultaneously, the heart rate detection module 3, in close contact with the skin behind the ear, continuously monitors heart rate changes using photoelectric methods. The collected physiological data, after being processed by the main control circuit board, can be stored locally or transmitted wirelessly (such as via Bluetooth) to terminal devices such as smartphones for display and analysis.

[0041] During use, the user wears the headphones, and the memory wire headband 1 and ear hooks 6 automatically fit the head and ears, with the inner side of the main shell 5 in contact with the skin. The bone conduction vibrator 2 transmits sound, and the heart rate detection module 3 collects heart rate signals. The data can be processed and stored locally via the main control circuit board, or transmitted to external devices via the charging data interface 4. Indicator lights display the status through indicator light holes 7. Finally, it should be noted that:

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
