Description

Technical Field

[0001] This invention relates to the field of electronic information technology, specifically to an ergonomically designed intelligent anti-loss bone conduction dual-channel and adaptive audio system. Background Technology

[0002] With the rapid development of the consumer electronics market, headphones, as a core audio output device, have seen their market size continue to expand. However, current mainstream headphone products still suffer from many pain points, seriously affecting user experience and resource utilization efficiency:

[0003] Poor wearing experience and health risks: The sealed environment of traditional in-ear headphones is prone to bacterial growth, causing ear canal pain, skin allergies, and even increasing the risk of otitis media; while the existing ear clip design avoids the problem of in-ear, it suffers from serious sound leakage due to unreasonable structure, and at the same time, it does not fit the auricle well enough, which can cause pressure when worn for a long time.

[0004] Battery life and charging issues are prominent: After 500 charge cycles, the battery capacity of a regular earphone charging case decreases to 80%, directly causing charging failure; the TWS (True Wireless Stereo) earphones have a tested battery life of only 4.2 hours, which is insufficient to meet users' needs for long-term use; in addition, frequent plugging and unplugging of Micro-USB, Type-C and other interfaces can easily cause poor contact and affect charging stability.

[0005] Easily lost and lacking protective mechanisms: Because the earphones do not fit tightly to the ears, they are easily lost during daily activities; at the same time, the devices lack effective identity authentication and tracking functions, making them difficult to find after being lost, resulting in a lot of waste of resources.

[0006] Audio output is affected by environmental interference: Traditional headphones cannot adjust audio parameters in real time according to ambient noise. In noisy scenes, the volume needs to be increased to hear clearly, which can damage hearing and fail to guarantee a clear audio experience. In quiet scenes, improper volume control can easily result in harsh sounds.

[0007] Therefore, an intelligent anti-loss bone conduction dual-guide and adaptive audio system based on ergonomics has become an urgent problem to be solved. Summary of the Invention

[0008] The purpose of this invention is to provide an ergonomic intelligent anti-loss bone conduction dual-guide and adaptive audio system to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the technical solution provided by the present invention is: an ergonomic intelligent anti-loss bone conduction dual-guide and adaptive audio system, including earphones, an earphone case and an APP backend;

[0010] The earphone adopts an asymmetrical T-shaped double curvature structure, including an earphone body, a touch screen, ear clips, ear hooks, a speaker head, a beam-directed microphone, a data / power interface, a cable mount, a built-in pull-wire microphone, and bone conduction points. The touch screen is located on the outer surface of the earphone body. The earphone body is connected to the speaker head via ear hooks. The ear clips are located on both sides of the earphone body. The beam-directed microphone is located on the speaker head. The data / power interface is located on the surface of the earphone body. The cable mount is located on the ear clips at the connection between the earphone body and the ear clips. The built-in pull-wire microphone is located on the outer side of the earphone body. The bone conduction points are located on the outer surface of the ear clips.

[0011] The earphone integrates a bone conduction dual-conduction system and a human bio-information acquisition module. The bone conduction dual-conduction system performs beam-directed sound transmission and self-adjustment to ambient noise. The integrated human bio-information acquisition module is used to collect human body temperature, pulse, blood pressure, heart sounds and brain waves, and to confirm whether the earphone is worn on the human ear based on the collected bio-information.

[0012] The earphone case incorporates a power amplifier, a multi-functional charging module, a data interaction module, and a temperature-controlled energy storage module. The power amplifier works with the earphones to enable audio playback and call functionality. The multi-functional charging module includes a photovoltaic charging unit, a wireless charging unit, and a wired charging unit, all three connected via a three-in-one charging management IC for intelligent priority switching. The data interaction module features a USB interface for data reading, wired charging, and switching between data reading and wired charging modes. The temperature-controlled energy storage module includes a battery insulation chamber, an electric heating component, and a heat dissipation component, providing heat replenishment at low temperatures and heat dissipation at high temperatures.

[0013] The APP backend is used for text recognition, voice input, multi-channel output, high and low audio limit adjustment, channel switching, periodic device status confirmation, power management, biometric information storage and real-time cross-language translation, and builds a suspected loss matching platform to realize information association and temporary calls when the device is abnormal.

[0014] Furthermore, the ear clip includes an integrated back-of-ear fitting part and a concha clamping part, as well as a self-adjusting module inside. The back-of-ear fitting part has a composite curved surface that matches the anatomical curvature of the posterior surface of the auricle. The concha clamping part is composed of a shape memory alloy skeleton and a silicone buffer layer forming a three-point dynamic clamping system. The self-adjusting module uses a piezoelectric drive component to adjust the clamping force of the ear clip in real time according to temperature and motion acceleration.

[0015] Furthermore, the implementation of the environmental noise self-adjustment includes at least one of the following:

[0016] Method 1: Spring physical adjustment method. The speaker head has a built-in spring. Starting from 16kHz, the distance to the sound source is adjusted by the extension and retraction of the spring to move the speaker head as the noise changes.

[0017] Method 2: Phased volume compensation method. Based on the continuous noise environment collected by the built-in pull-wire microphone of the headset, the output volume is adjusted from 6dB to 24dB within the user-defined volume range. The collection period is set by the user.

[0018] Method 3: Adjust voice parameters based on user biometric recognition and user password;

[0019] Method 4: Bone conduction compensation method, which uses a bone conduction dual-conduction system to compensate for bone conduction in the 500-4000Hz frequency band when noise is perceived.

[0020] Furthermore, the earphone case includes a case body, a case lid, a button area, a data interface, a photovoltaic panel, a speaker window, and a sound transmission window for the earphones;

[0021] The lid is hinged to the body of the box; the button area is located on one side of the body of the box; the data interface is located on the other side of the body of the box and is opposite to the button area; the photovoltaic panel is located on the surface of the lid; the speaker window and the sound transmission window for headphones are located on the same side of the body.

[0022] The box contains several T-shaped bases for holding ear clips. One side of each T-shaped base has a T-shaped bead slot for holding the speaker head. The T-shaped base has an information and power port, and the T-shaped bead slot has a speaker channel. The speaker head of the earphone works in conjunction with the speaker window of the earphone box and the earphone's sound transmission window through the speaker channel to achieve sound and call functions. The box also contains a battery area for storing a temperature-controlled battery module.

[0023] Furthermore, the battery area is electrically connected to the photovoltaic charging unit, the wireless charging unit, and the wired charging unit. The wireless charging unit adopts a ring array coil layout and is equipped with an ultraviolet disinfection module with a wavelength of 275nm.

[0024] Furthermore, the workflow of the suspected mismatch recruitment platform is as follows:

[0025] When communication between the earphone and the APP platform is confirmed to be abnormal and the device is in the first-recognition locked state, the earphone information enters the suspected lost and found state; or after the user reports the lost device information to the suspected lost and found platform, the suspected lost and found platform performs multiple matching confirmations on the reported information and the earphone information in the suspected lost and found state, and forms an information association after a successful match; with the user's permission, information communication can be realized between the lost party and the found party, or a temporary direct call can be established between the two parties and the suspected lost earphone. The temporary call supports voice changing function, and the suspected lost and found platform does not display any party's personal data information or location information; the suspected lost and found platform complies with the ETSI EN303645 network security standard.

[0026] Furthermore, the external cable bayonet is connected to a cable socket and a data / power interface for switching the headset from wireless mode to wired mode;

[0027] The touchscreen is used to control various functions of the headphones. The bone conduction dual-conduction system uses 16kHz-25kHz high-frequency bone conduction sound waves to achieve distance perception based on the phase difference of bone conduction sound waves. Combined with magnetic direction and bio-positioning, it confirms the left and right ear status of the headphones, thereby realizing personalized mono, mixed, left and right channel output, and integrated sound effects of bone conduction and air conduction.

[0028] Furthermore, after the earphones are placed in the earphone case, the speaker head, through the speaker channel, works with the speaker window and the earphone sound transmission window to achieve the sound function. At this time, the earphones are charged and used as speakers inside the case, and the built-in pull-wire microphone also works normally inside the case.

[0029] Furthermore, it also includes an anti-loss mechanism, which includes first recognition locking, multi-factor authentication, flashing and vibration tracking, periodic device confirmation after silence, and sleep-related fall-free alarm.

[0030] The multi-factor authentication includes address code authentication, physical layer radio frequency fingerprint recognition, transport layer quantum random number encryption, protocol layer BLE5.3+Thread authentication, application layer FIDO2-based voiceprint key authentication, behavior layer LSTM anomaly detection, and memory confirmation. The memory confirmation requires verification of behavioral features and biometric features.

[0031] The flashing, sound, and vibration tracking is achieved through the earphone's own lights, sound, and bone conduction vibration points. It adopts a combination alarm of at least two of the following: sound, light flashing, and vibration. The sound is a buzzing sound with fluctuations of 70-85-70dB, the light flashing is a multi-color LED flashing at a frequency of 2Hz±10%, and the vibration is a fluctuating vibration with an amplitude of 0.1-0.25mm in the 20Hz-40kHz frequency band.

[0043] The following detailed description of the ergonomically designed intelligent anti-loss bone conduction dual-guide and adaptive audio system based on the accompanying drawings is provided in further detail.

[0044] Combined with appendix Figure 1-3 This invention will be described in detail below.

[0045] The ergonomically designed intelligent anti-loss bone conduction dual-guide and adaptive audio system mainly consists of three parts: earphone 1, earphone case 2, and APP backend. The structure and function of each part are as follows:

[0046] The earphone 1 adopts an asymmetrical T-shaped double curvature structure to adapt to different users' ear shapes and achieve a comfortable wearing experience. Its structural components include the earphone body 3, touch screen 4, ear clip 5, ear clip 6, speaker head 7, directional microphone 8, data / power interface 9, cable mount 10, built-in pull-wire microphone 11, and bone conduction vibration point 12.

[0047] A touchscreen 4 is located on the outer surface of the headphone body 3 and is used to control various headphone functions. The headphone body 3 is connected to the speaker head 7 via an ear clip 6, and ear clips 5 are located on both sides of the headphone body 3. A directional microphone 8 is located on the speaker head 7, and a data / power interface 9 is located on the surface of the headphone body 3. A cable clip 10 is located on the ear clip 5 at the connection between the headphone body 3 and the ear clip 5. A built-in pull-wire microphone 11 is located on the outer side of the headphone body 3, and a bone conduction vibration point 12 is located on the outer surface of the ear clip 5.

[0048] The bone conduction dual-channel system integrates beam-directed sound transmission and ambient noise self-adjustment. The beam-directed sound transmission function forms a sound beam through the beam-directed sound tube 8, reducing volume loss and sound leakage without affecting the transmission of external sounds. The ambient noise self-adjustment function automatically adjusts the output speaker volume or speaker distance based on ambient sound (ambient sound sampling rate 44.35-47.85kHz) and user needs, improving noise immunity. There are four specific implementation methods:

[0049] Spring-based physical adjustment method: The headphone speaker uses a spring design, starting at 16kHz. The speaker displacement is adjusted by the extension and retraction of the spring as the noise changes, thereby changing the distance to the sound source to suppress the noise.

[0050] Phased volume compensation method: Based on the noise environment continuously collected by the headphone microphone (the collection period is set by the user), noise reduction adjustment is performed within the user-defined volume range (6dB-24dB);

[0051] User biometric identification voice tuning method: Adjust the voice parameters according to the user's password to meet the user's wishes;

[0052] Bone conduction compensation method: bone conduction compensation is performed when noise is perceived, with the compensation frequency range being 500-4000Hz.

[0053] The human bio-information acquisition module integrates sensors to collect bio-information such as body temperature, pulse, blood pressure, heart sounds, and brain waves. Based on this information, it can confirm whether the earphone is being worn on the ear, providing a basis for the anti-loss mechanism.

[0054] The mode switching function connects to the data / power interface 9 via the external cable connector 10, which connects to the external cable connector 10. This allows the wireless headphones to be switched to wired mode, reducing sound latency and meeting the needs of scenarios with high requirements for audio latency.

[0055] The asymmetric T-shaped double curvature structure has a horizontal arm curvature radius of 5-15mm±2mm (fitting the helix crus and concha), and the vertical arm (postauricular region or postauricular attachment) adopts a gradual curvature design (15mm-5mm transition, curvature change rate ≤2mm / 10). Both can be equipped with an active adaptation mechanism.

[0056] Material selection: Silicone cushioning layer thickness 0.8-1.2mm, density 1.1-1.3g / cm³ 3 The shape memory alloy skeleton uses Ni-Ti alloy with a phase transformation temperature of 25-32℃.

[0057] Equipped with a pressure sensor-based clamping force feedback system, it automatically triggers a 0.5mm rebound buffer when the concha pressure is detected to be >25kPa; the clamping contact surface adopts a zoned hardness design (Shore hardness of 50A±5 in the tragus area and 70A±5 in the antihelix area), releasing 5% of the clamping force every 30 minutes of continuous wear, and automatically releasing 30% of the clamping force after 4 hours, ensuring long-term wearing comfort.

[0058] The headphone case 2 includes a case body 13, a case cover 14, a button area 15, a data interface 16 (for charging and wired connection), a photovoltaic panel 17, a speaker window 18, and a sound transmission window 19 through the headphones; the inside of the case body 13 is provided with a T-shaped bead groove 21, a T-shaped base 20, a speaker channel 23, an information and power port 22, and a battery area 24.

[0059] The lid 14 is hinged to the body 13. The button area 15 is located on one side of the body 13, and the data interface 16 is located on the other side of the body 13, opposite to the button area 15. The photovoltaic panel 17 is located on the surface of the lid 14. The speaker window 18 and the sound transmission window 19 through the headphones are located on the same side of the body 13. The T-shaped base 20 inside the body 13 is used to place the ear clip 5 of the headphones. The T-shaped bead slot 21 is used to place the speaker head 7 of the headphones. The speaker channel 23 connects the T-shaped bead slot 21 to the sound transmission window 19 through the headphones. The information and power port 22 is connected to the data / power interface 9 of the headphones. The battery area 24 is used to place the rechargeable battery and the temperature control component.

[0060] The amplifier assembly has a built-in speaker and audio processing unit, which, together with the headphones, enables audio playback and call functions. When the headphones 1 are placed in the headphone case 2, the speaker head 7, through the speaker channel 23, combined with the speaker window 18 and the headphone sound transmission window 19, realizes the speaker function. The headphones can also be used as speakers while charging in the case. The built-in pull-wire microphone 11 can also work normally in the case. The three-device design in one case allows the headphone case 2 to function as a microphone when making calls with the headphones being worn. With the help of manual control buttons and the APP, the headphone case 2 and the microphone can form a call and have a simultaneous audio translation function.

[0061] The multi-functional charging module includes a photovoltaic charging unit, a wireless charging unit, and a wired charging unit, which are intelligently prioritized through a three-in-one charging management IC. The photovoltaic charging unit collects solar energy for charging through the photovoltaic panel 17; the wireless charging unit adopts a ring array coil layout and is equipped with a 275nm wavelength ultraviolet disinfection module, which can work in conjunction with the wireless charging and also has a reverse charging function; the wired charging unit is charged through the data interface 16.

[0062] The data interaction module is equipped with a USB interface (data interface 16), which supports data reading and wired charging functions. It has a dual-mode switching mechanism (automatic identification of data / charging modes) and a 3A fuse protection circuit for reverse charging to ensure charging safety.

[0063] Temperature-controlled energy storage module: includes a rechargeable battery insulation chamber, an electric heating component, and a heat dissipation component. At low temperatures (temperature threshold 7℃±2℃), the electric heating component provides supplemental heat to the battery to ensure continuous charging capability; at high temperatures (temperature threshold 55℃±2℃), the open-box heat dissipation function or phase change heat absorption function is activated to reduce the battery temperature and ensure battery safety and lifespan.

[0064] As the core of system control and data management, the APP backend has the following functions:

[0065] Text processing and audio adjustment functions: Supports text recognition and voice input; features multi-channel output with multi-connection capability and multi-channel adaptive allocation technology; allows for high and low audio limit adjustment, achieving high-volume lowering (high volume down, low volume up) to prevent ear-piercing damage and provide hearing compensation; supports user-defined switching between single, left, and right channels.

[0066] Device management functions: Regularly check device status and warn of potential earphone loss when not in sleep mode; support high battery rejection (adjustable via APP) to prevent charging within the set battery range; record accumulated usage time and display it in the background; indicate the total battery level in the earphone case 2; and have high temperature (55℃±2℃) over-temperature protection reminder and low temperature (7℃±2℃) electric heating function for the battery case.

[0067] Anti-loss and data management functions: A suspected loss matching platform is built. When the communication between the earphone and the APP is abnormal and the earphone is in the first recognition lock state, the earphone 1 information enters the suspected loss matching state. After the reported information is confirmed by multiple matching, information communication or temporary direct calls can be realized with the user's permission (supports voice changing, does not display personal data and location information, and complies with the ETSI EN303645 network security standard); stores the biometric data information collected by the earphone 1, and uses medical-grade data encryption to protect privacy.

[0068] Other features: Supports real-time cross-language translation; features a battery health prediction system based on usage habits and a battery management system with temperature compensation; and a 3D audio rendering engine compliant with ISO / IEC 23003-3 standards to enhance the audio experience.

[0069] This system employs multiple anti-loss mechanisms to ensure device safety, specifically including:

[0070] First-time authentication lock: After the first pairing confirmation of the earphone 1, you can choose not to undergo secondary authentication without confirmation from the original mobile phone to prevent the device from being used illegally.

[0071] Multi-factor authentication: The authentication process involves address code → physical layer (RF fingerprint recognition) → transport layer (quantum random number encryption) → protocol layer (BLE5.3+Thread) → application layer (FIDO2-based voiceprint key) → behavior layer (LSTM anomaly detection) → memory confirmation (behavioral features + biometric features), rejecting the processing of information from non-original authentication devices.

[0072] Flash, sound, and vibration tracking: Utilizing the earphone 1's own light, sound, and bone conduction vibration point 12, a combination alarm of at least two of the following can be achieved (70-85-70dB fluctuating buzzer, multi-color LED frequency 2Hz±10% strobe, frequency band 20Hz-40kHz amplitude 0.1-0.25mm fluctuating vibration); in emergency search, the full mode (85dB / 3Hz / 0.25mm) is triggered to facilitate the user's location of the earphone 1.

[0073] After the sound stops, the device is checked periodically: After the sound stops on the earphone 1, the device is checked once every time period. If the check is abnormal, the user will be notified in time.

[0074] Sleep-related earphone fall-out warning: By recognizing the user's sleep state through biometrics, if the earphone falls out during sleep, no warning will be given to avoid disturbing the user.

[0075] The specific implementation process of the ergonomically designed intelligent anti-loss bone conduction dual-guide and adaptive audio system of this invention is as follows:

[0076] Example 1

[0077] Please see Figure 1 The headset 1 can be controlled via the headset touchscreen 4; when making a call, due to the microphone on the headset 1 being easily interfered with, you can directly use the mobile phone to make a call, or pull out the built-in pull-out microphone 11 in the headset 1 to make a call; or, if you cannot accept the delay, you can directly turn the wireless headset into a wired headset by connecting the designed cable holder through the cable slot 10 and the data / power interface 9; or, under certain power switch conditions, you can speak into the headset box 2 (provided there is a Bluetooth headset inside) and make a call instead of the headset 1 being returned to its original position; all of the above calls can realize the transliteration (dialects and foreign languages) function.

[0078] Example 2

[0079] Please see Figure 1 The earphone 1, via the ear clip 5 and ear hook 6, connects to the anticonch cavity through the speaker head 7, forming an adjustable clip that adapts to the ear and provides support, achieving a comfortable and secure fit. After wearing, the earphone transmits sound through the microphone 8, reducing volume and sound leakage without obstructing external sound. It also works in conjunction with the bone vibration function of the upper and lower bone transmission points 12 matched to the ear clip 5, transmitting sound vibrations through the mastoid process of the temporal bone.

[0080] Example 3

[0081] Please see Figure 2The earphone case 2 can be self-charged using the photovoltaic panel 17; it can also be wirelessly charged using the wireless charging coil below; or it can be charged using the data interface 16 (which can be charged and connected to a wired card slot); to ensure the continuous charging capability of the device, a rechargeable battery insulation chamber is set up, and in low temperatures, it is heated by the electric heating of the battery area 24, thereby ensuring the continuous use of the rechargeable battery. In high temperatures, it has a high temperature reminder and a heat dissipation function when the case is opened.

[0082] Example 4

[0083] Please see Figure 2 Under the control of the button area 15, when at least one earphone 1 is inside the earphone box 2, the speaker head 7 of the earphone 1, through the speaker channel 23, together with the speaker window 18 of the earphone box 2 itself and the sound transmission window 19 through the earphone, plays the role of sound and call.

[0084] Example 5

[0085] Please see Figure 3 The earphone 1 is inside the earphone case 2, where it can be charged or used as a speaker while charging. The earphone microphone can also be used in the earphone case 2.

[0086] Example 6

[0087] Earphone 1 has five layers of anti-loss functions. First, it provides flashing lights and a sound alert for loss. Second, it has a bioelectrical confirmation function; if earphone 1 is not on the remote or in the box, an alarm will sound. Third, it has a location confirmation function within a certain time period; if it is not in the earphone box 2 or within the recognition range, it will prompt you to search via the APP platform and record the time of signal loss. Fourth, it has a mobile phone confirmation and locking function; after connection confirmation, the device can be locked to the phone. Once locked, the device cannot be used without multi-factor authentication (address code + protocol stack layer + RF communication layer + memory confirmation). Fifth, if lost after locking, as long as the device is logged into the APP platform and the lost earphone 1 is locked, the information will be directly transmitted to the suspected lost and found platform. Both lost earphone 1s can be registered in the APP's suspected lost and found platform. After multi-factor matching confirmation, with user permission, communication can be established to locate earphone 1.

[0088] Example 7

[0089] A corresponding app can be installed on the audio output device (such as a mobile phone). The app has text recognition and voice input functions; it also has a multi-channel output function for multiple devices; it has a high and low audio limit adjustment function, and can limit the high volume and pull down the low volume (high volume down, low volume up); it also has a single, left, and right channel switching function; it also has a periodic device status confirmation function, and can predict the possible loss of the headphones when not in sleep mode; it also has a function to refuse charging when the headphones have a high battery within the set battery level; it also has a background display of accumulated usage time; and it also has a function to remind users when the battery case is at a high or low temperature.

[0090] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
