[0001] The present invention relates to the field of earphone technology, and in particular to an earphone switching method based on bone conduction and air conduction dual modes. Background Art

[0002] With the continuous development of audio technology, headphones, as an indispensable audio device in people's daily life, are also constantly improving in function and performance. Traditional headphones mainly convert audio signals into sound wave signals through air conduction and transmit them to the user's auditory system through the air. However, this single conduction method has certain limitations in certain specific scenarios. For example, in a high-noise environment, users may need a higher volume to hear the audio content clearly, but this may cause damage to the user's hearing.

[0003] In order to solve this problem, bone conduction headphones have appeared in recent years. Bone conduction headphones convert audio signals into vibration signals through bone conduction transducers, and transmit them to the user's skull through vibrations, and then to the auditory system. This method does not require sound waves to be transmitted through the air, so it can reduce the interference of external noise to a certain extent, while avoiding direct stimulation of the eardrum, which is beneficial to protecting the user's hearing.

[0004] However, existing bone conduction headphones and air conduction headphones are often two independent products, and users need to choose different types of headphones according to different usage scenarios; this not only increases the purchase cost for users, but also brings inconvenience in use; therefore, the market urgently needs a headset that can have both bone conduction and air conduction modes and can be flexibly switched according to user needs.

[0005] In addition, during the switching of the working modes of the headphones, how to ensure the stable transmission of audio signals and how to automatically adjust the volume and audio processing parameters of the headphones to adapt to the auditory effects in different modes are also problems to be solved by current technology.

[0028] In this embodiment, receiving the user input signal includes: receiving the user input signal through a physical button on the headset; receiving the user input signal through a physical button on the headset. This method is direct and clear, and the user only needs to press a preset physical button on the headset to send a corresponding instruction or select a desired function; the design of the physical button is usually ergonomic, which is convenient for the user to operate with one hand, and the input can be easily completed even without visual assistance; The user input signal is received through the touch sensing area on the headset; the touch sensing area can recognize the user's touch actions, such as light touch, slide or long press, to trigger different functions or commands; this method not only enhances the sense of technology of the headset, but also allows users to operate through more intuitive and natural gestures, further simplifying the operation process; Receive user input signals through the mobile device paired with the headset; mobile devices (such as smartphones, tablets, etc.) are usually equipped with more abundant input methods, such as keyboards, touch screens, etc. Users can input commands or select functions on the mobile device, and then transmit the signals to the headset through wireless communication technologies such as Bluetooth; this method enables users to view and select options on a larger screen, improving the accuracy and convenience of operation; The user's voice commands are received as input signals through voice recognition technology; the user only needs to verbally speak the commands or requirements, and the headset can parse and execute them through the built-in voice recognition engine; this method not only greatly improves the convenience of operation, but also allows users to easily control the headset even when both hands are occupied, bringing users a more free and efficient interactive experience.

[0029] In this embodiment, the switching mechanism for controlling the earphones includes: controlling the power switch of the bone conduction transducer and the air conduction speaker; allowing the user to independently turn on or off the bone conduction transducer and the air conduction speaker according to actual needs; for example, in a noisy environment, the user may prefer to use the air conduction speaker to obtain clearer sound quality; and in situations where environmental alertness needs to be maintained, such as outdoor sports or cycling, the bone conduction transducer becomes a more ideal choice, allowing the user to clearly hear the outside world while listening to music; Control the switching of the signal pathways between the bone conduction transducer and the air conduction speaker; allow the headset to automatically or manually switch between the two conduction modes according to the user's instructions or preset conditions; for example, when the user moves from a quiet indoor environment to a noisy outdoor environment, the headset can automatically switch to the air conduction speaker to ensure the clarity and stability of the sound quality; conversely, when the user returns indoors or needs to reduce external interference, the headset will automatically switch back to bone conduction mode; Controls the volume and audio processing parameters of the bone conduction transducer and air conduction speaker; allows users to fine-tune the volume, sound quality style (such as bass enhancement, treble clarity, etc.) and audio processing parameters (such as noise reduction level, equalizer settings, etc.) of the headphones according to personal preferences and hearing needs; through these adjustments, users can ensure that the headphones can provide the best listening experience in different environments.

[0030] In this embodiment, monitoring the contact state between the earphone and the user includes: using a pressure sensor to monitor the contact pressure between the earphone and the user's skin; the pressure sensor can accurately measure the pressure distribution between the earphone and the user's head or ear skin, ensuring that the earphone is neither too tight to cause discomfort nor too loose to cause sound leakage or instability when worn; by adjusting the wearing position of the earphone or the internal support structure in real time, the pressure sensor can help the earphone achieve the best fit and comfort, thereby improving the user's wearing experience; Capacitive sensors are used to monitor changes in the contact capacitance between the earphones and the user's skin. Capacitive sensors evaluate the contact status by measuring the capacitance value formed between the earphones and the user's skin. When the earphones are in close contact with the user's skin, the capacitance value will change, and this change can be captured by the sensor and converted into an electrical signal, which is then used to determine the wearing condition of the earphones. Through the monitoring of the capacitive sensor, the earphones can intelligently identify whether the user is wearing them, thereby automatically adjusting the playback status or performing other intelligent operations, such as pausing playback, lowering the volume, etc. Use proximity sensors to monitor changes in the distance between the earphones and the user's skin. The proximity sensor detects the distance between the earphones and the user's skin by emitting and receiving electromagnetic waves. When the earphones are close to the user's skin, the sensor can sense the proximity and respond accordingly. It not only helps the earphones to achieve more accurate wearing detection, but can also be used to implement some advanced functions, such as automatically pausing playback when the user takes off the earphones, or automatically adjusting the volume when the earphones are close to the user's ears.

[0031] In this embodiment, automatically adjusting the volume and audio processing parameters of the headset includes: automatically adjusting the volume according to the preferences set by the user; when the user wears the headset, the built-in system of the headset automatically adjusts the output volume of the headset according to the volume previously set by the user, ensuring that the ideal volume level is obtained every time it is used; this personalized volume adjustment not only improves the user's hearing experience, but also helps protect the user's hearing health and avoids hearing damage caused by long-term exposure to high-volume environments; Automatically adjust noise reduction parameters according to the ambient noise level; through the built-in microphone and sensor, the headset can monitor the noise level of the surrounding environment in real time, and automatically adjust the noise reduction parameters according to the noise intensity. For example, in noisy public places, the headset will automatically enhance the noise reduction effect to reduce the interference of external noise; in a relatively quiet environment, it will appropriately reduce the noise reduction intensity to maintain a natural sound experience; this intelligent noise reduction adjustment not only improves the sound quality of the headset, but also enhances the user's auditory comfort in different environments; Automatically adjust the audio equalizer settings based on the user's auditory feedback; the audio equalizer is an important tool for adjusting sound quality. By adjusting the sound gain in different frequency bands, the overall balance and style of the tone can be changed; the headphones have a built-in intelligent audio analysis system that can analyze the user's auditory feedback and preferences, and automatically adjust the audio equalizer settings based on the analysis results; for example, if the user prefers music with prominent bass effects, the headphones will automatically increase the gain of the low-frequency band; and if the user prefers clear treble effects, the gain of the high-frequency band will be increased accordingly; this intelligent audio equalizer adjustment not only meets the user's needs for personalized sound quality, but also improves the overall sound quality performance of the headphones.

[0032] In this embodiment, the feedback mechanism includes: collecting the user's auditory feedback information in real time; the headset has multiple sensors and monitoring technologies built in, which can capture the user's auditory response in real time when using the headset; these responses may include the user's adjustment of the volume, preference adjustment of the audio equalizer, and evaluation of the noise reduction effect; by collecting these feedback information, the headset can fully understand the user's auditory needs and preferences, and provide data support for subsequent analysis and adjustment; Analyze the user's auditory feedback information to determine the adjustment direction of the audio signal; the built-in audio processing system of the headset will analyze the collected auditory feedback information and identify the user's auditory characteristics and preferences through algorithms and models; for example, analyze the user's sensitivity to bass, mid-range and treble, as well as the preference for different instruments and human voices; based on these analysis results, the system can determine the adjustment direction of the audio signal, that is, which frequency bands should increase or decrease the sound gain to better meet the user's auditory needs; Based on the analysis results, the output of the audio signal is automatically adjusted to optimize the user's auditory experience; once the adjustment direction of the audio signal is determined, the built-in audio processing system of the headset will automatically adjust the output of the audio signal according to the analysis results; this adjustment may involve volume, audio equalizer, noise reduction parameters and other aspects, aiming to optimize the user's auditory experience; through continuous iteration and adjustment, the headset can gradually adapt to the user's auditory preferences and provide a more personalized sound quality experience.

[0033] In this embodiment, the earphone includes at least one bone conduction transducer and at least one air conduction speaker; the bone conduction transducer is close to the ear or skull of the user, and the bone conduction transducer can directly convert the audio signal into mechanical vibration, which is then transmitted to the inner ear through the bones, so that the user can hear the sound clearly even without blocking the ear canal; this design is particularly suitable for sports, commuting or occasions where environmental alertness needs to be maintained; Air conduction speakers generate sound waves by vibrating air molecules, which are captured by the user's ears and converted into auditory signals; air conduction speakers can provide a wider sound field and richer sound details, especially suitable for enjoying high-quality music or making voice calls in a quiet environment; The headset also includes: a control unit for processing user input signals and controlling the switching mechanism; the control unit is responsible for processing user input signals, such as key operations, touch sensing or voice commands, and controlling the switching mechanism according to the user's intention; the switching mechanism can intelligently switch between bone conduction and air conduction to ensure that the user can get the best hearing experience in different scenarios; An audio processing unit that processes audio signals and adjusts output according to the working mode; the audio processing unit is responsible for processing signals from the audio source and adjusting output according to the working mode of the headset; for example, in bone conduction mode, the audio processing unit may optimize the low-frequency signal to enhance the clarity of bone conduction; while in air conduction mode, it may enhance the details and three-dimensional sense of the high frequency band. By intelligently adjusting the audio signal, the audio processing unit can ensure that users can enjoy balanced and high-quality sound in different modes; A power management unit, used to manage the power supply of the headset and ensure stable power supply during the switching process; the power management unit is responsible for managing the power supply of the headset to ensure stable power supply during the switching process; including components such as batteries, charging circuits and power management chips to provide long-lasting battery life and support fast charging functions; by precisely controlling the distribution and use of power, the power management unit can ensure that the headset can maintain stable performance in various usage scenarios.

[0034] In this embodiment, the headset further includes an environmental noise detection unit, which is used to detect the environmental noise level around the headset, and use the detection result to automatically adjust the audio processing parameters of the headset; the built-in environmental noise detection unit of the headset is a highly sensitive and intelligent component; using microphone technology and signal processing algorithms, it can capture and analyze the noise level in the environment around the headset in real time; this function is not limited to simple noise recognition, but can also accurately quantify the intensity, frequency distribution and dynamic changes of the noise, thereby providing accurate data support for subsequent audio processing; When the ambient noise detection unit captures a noise signal, it immediately transmits this information to the audio processing unit of the headset; the audio processing unit intelligently adjusts the audio processing parameters of the headset based on the noise data received; for example, in a noisy public place, the ambient noise detection unit may detect a higher noise level, at which point the audio processing unit will automatically increase the strength of the noise reduction algorithm to reduce the interference of external noise on the sound quality of the headset; in a relatively quiet environment, the audio processing unit will adjust the equalizer settings accordingly to enhance the details and layering in the music, allowing users to hear every note and sound detail more clearly; The ambient noise detection unit can also make personalized audio adjustments based on the user's actual usage. For example, when the user is exercising, the earphones may automatically switch to bone conduction mode to reduce the pressure on the ears, and adjust the noise reduction parameters in real time through the ambient noise detection unit to ensure that the user can enjoy clear and stable sound during exercise. When the user is in a quiet learning or working environment, the earphones will pay more attention to the true restoration and detail performance of the sound, providing users with a purer and more delicate sound quality experience. In addition to automatically adjusting audio processing parameters, the ambient noise detection unit can also provide users with a more intelligent interactive experience; for example, when it detects that the user is in a call, the headset will automatically enhance the microphone's sound reception and reduce background noise interference to ensure call clarity and stability; and when it detects that the user takes off the headset, the headset will automatically pause music or lower the volume to avoid unnecessary sound interference.

[0035] In this embodiment, the headset further includes a user behavior recognition unit, which is used to recognize the user's behavior pattern and predict the user's mode switching needs based on the recognition results, so as to adjust the mode of the headset in advance; the user behavior recognition unit is an intelligent component inside the headset, and the built-in sensor technology and machine learning algorithm can accurately capture and analyze various user behavior patterns; these behavior patterns include but are not limited to the user's movement state (such as walking, running, riding), head posture (such as wearing, taking off, tilting), and interactive actions (such as touch, voice commands), etc.; through continuous learning and optimization, the user behavior recognition unit can gradually establish a deep understanding of the user's daily behavior habits, providing a solid foundation for subsequent mode switching predictions; When the user performs a specific behavior, the user behavior recognition unit will start immediately and quickly analyze the match between the current behavior and the user's preset preferences or historical behavior patterns. For example, when the user starts jogging, the recognition unit can quickly recognize this behavior and predict that the user may want to switch to sports mode to get a more dynamic and rhythmic music experience. The headphones will adjust the audio settings in advance, such as enhancing the bass effect, increasing the volume, and may activate bone conduction technology to reduce pressure on the ears, ensuring that the user can enjoy clear and comfortable sound quality even during exercise. The user behavior recognition unit can also predict the user's need to switch modes based on the user's head posture or interactive actions. For example, when the user gently touches the side of the earphone, the recognition unit may predict that the user wants to switch songs or adjust the volume, so the earphone will immediately respond to this prediction and perform the corresponding operation. When the user takes off the earphone, the recognition unit may predict that the user does not need the earphone service temporarily, so the earphone will automatically pause playback to save power and avoid unnecessary noise interference. The user behavior recognition unit can also continuously optimize its prediction model based on the user's usage habits to improve the accuracy and efficiency of the prediction; this means that over time, the headphones will understand the user better and better and provide more personalized services; for example, if the user often practices meditation at a certain time period, the headphones may automatically switch to meditation mode at this time and play soft music to help the user relax.

[0036] In this embodiment, the headset also includes a health monitoring unit for monitoring the user's physiological parameters and adjusting the audio output of the headset according to the monitoring results to adapt to the user's physiological state; the health monitoring unit is a component inside the headset that integrates multiple sensors and intelligent algorithms. It can monitor the user's physiological parameters in real time, including but not limited to heart rate, blood pressure (through indirect measurement, such as pulse wave transmission time estimation), respiratory rate, body temperature, and sleep quality. These physiological parameters are important indicators reflecting the user's health status. Through continuous monitoring, the health monitoring unit can provide the user with real-time health feedback and adjust the audio output of the headset according to the monitoring results to adapt to the user's physiological state; When the user wears the headphones for activities, the health monitoring unit will start immediately and begin to capture the user's physiological data through the built-in sensors. For example, when the user performs high-intensity exercise, the heart rate and breathing rate will increase significantly. The health monitoring unit can capture these changes in real time and predict that the user may want to listen to more dynamic and inspiring music to maintain exercise. The headphones will automatically adjust the audio settings, such as enhancing the rhythm and dynamics, to match the user's exercise rhythm and enhance the exercise experience. The health monitoring unit can also intelligently adjust the audio output of the headphones according to the user's sleep quality. When the user enters the deep sleep stage, the headphones may automatically play soft white noise or natural sounds, such as the sound of waves and rain, to help the user relax and fall asleep better; when the user is in the light sleep or REM (rapid eye movement) sleep stage, the headphones may reduce the volume or switch to softer music to avoid disturbing the user's sleep; In addition to adjusting audio output according to physiological status, the health monitoring unit can also provide users with health reminders and suggestions. For example, when the user's heart rate rises abnormally, the headset may emit a slight vibration or voice reminder, suggesting that the user take a proper rest or do relaxation exercises; and when the user's sleep quality is poor, the headset may provide suggestions for improving sleep, such as adjusting the work and rest schedule, reducing caffeine intake, etc. The health monitoring unit can also synchronize with the user's smartphone or other health monitoring devices (such as smart watches, health bracelets, etc.) to achieve data sharing and analysis; so that users can not only view their physiological parameters on the headphones, but also obtain more detailed and comprehensive health reports and suggestions through the application on the smartphone.
