[0028] Wherein, one end of the first connecting rod 15 is connected with the first round wheel 13, and the first connecting rod 15 penetrates the second round wheel 14 and is connected with the shrinkable rod 16.

[0029] Wherein, a small hole is arranged on the outer surface of the shell body 1, and the earphone wire 10 is connected with the voice coil 7 in the shell body 1 through the small hole.

[0030] Wherein, the winding wheel 11 is composed of the first round wheel 13 and the second round wheel 14, the diameter of the first round wheel 13 and the second round wheel 14 is 2cm-3cm, and the winding wheel 11 is connected with the earphone wire 10.

[0036] It needs to be explained that the application is a Bluetooth headset with bone conduction and air conduction dual-mode switching. In use, the shell body 1 accommodates all the internal parts, and can be inserted into the ear, the foam sleeve 2 can protect the ear when the shell body 1 is inserted into the ear, and the sound hole 3 is the perfect music, the speaker is an audio coil 7, which pushes the cone 4 to sound when current flows, and the earphone directly makes the audio coil 7 on the membrane, which pushes the membrane to sound when current flows. The sound emitting unit of the earphone can convert the audio signal (electric energy) into sound, which is due to the magnetic field 6 formed by the magnet 6 and the interaction of the coil passing through the audio signal, so that the earphone diaphragm moves forward and backward to vibrate the air to emit sound. The iron core 9 enables the magnet 6 to be used. When the earphone wire 10 needs to be accommodated, the first circular wheel 13 and the four circular wheels 14 on the winding wheel 11 are connected with the first connecting rod 15. Place the earphone wire 10 on the first connecting rod 15, shake the second connecting rod 17, the second connecting rod 17 is connected with the first connecting rod 15 through the pull rod 16, when the second connecting rod 17 is shaken, the first connecting rod 15 is driven to rotate, and the earphone wire 10 is accommodated. When the second connecting rod 17 needs to be accommodated, press the pull rod 16, and the second connecting rod 17 is pressed into the groove 12. At the same time, it needs to be explained that the specific implementation of the bone conduction and air conduction dual-mode Bluetooth headset of the application is as follows: structure design: the earphone shell is provided with a bone conduction vibration unit and an air conduction speaker unit. The bone conduction unit transmits sound to the temporal bone through an internal vibration transmission path, and the air conduction unit transmits sound to the ear canal through an acoustic channel. The dual-mode switching circuit connects the two units to ensure seamless switching.

[0037] Intelligent control: the earphone is provided with a Bluetooth module and a control chip, which can switch modes through control buttons or automatically detect the wearing state. The environmental noise sensor collects external noise, and the intelligent power consumption module adjusts the output mode and power to realize long-time use and low energy consumption.

[0038] Acoustic optimization: low-frequency enhancement structure and noise reduction structure improve the low-frequency performance and clarity of bone conduction, and the sound quality optimization circuit performs dynamic equalization processing according to sensor feedback.

[0039] Operation process: after the user wears the earphone, the earphone automatically detects the wearing state. If the environmental noise is high, the bone conduction mode is preferentially enabled to improve the clarity; in a quiet environment, the air conduction mode can be automatically or manually switched to enhance the low-frequency experience. During the switching process, the dual-mode switching circuit ensures smooth switching of the signal without sound interruption.

[0040] Charging and endurance: the earphone battery is charged through the charging interface, and the power management module realizes fast charging and safety protection, and adjusts the power consumption according to the mode selection.

[0041] The bone conduction vibration unit converts electrical signals into mechanical vibrations through a micro driver, which are transmitted along a vibration conduction path to the user's temporal bone, allowing the user to perceive sound directly through the bone. The air conduction speaker unit, on the other hand, converts electrical signals into air vibrations, which are transmitted through the ear canal to the eardrum, achieving traditional auditory transmission. The dual-mode switching circuit routes audio signals to the corresponding unit based on user selection or intelligent detection signals, while managing power output to ensure sound quality.

[0042] The Bluetooth module is responsible for receiving wireless audio signals and transmitting them to the signal processing chip, which optimizes sound quality in real time based on sensor feedback, including low-frequency enhancement, environmental noise compensation, and dynamic equalization. The microphone collects external sounds and user voices for noise reduction and communication functions, and the control buttons allow users to manually switch modes or adjust the volume.

[0043] The environmental noise sensor continuously collects external noise intensity, and the earphone wear detection sensor detects whether it is properly worn. If it detects abnormal wear or excessive environmental noise, the intelligent power management module will switch to bone conduction mode while reducing power consumption, allowing for comfortable long-term wear. The ear hook structure and internal support frame ensure stable bone conduction vibration transmission while maintaining balanced air conduction sound quality.

[0044] When the user communicates in a noisy environment, the bone conduction vibration unit provides clear sound, while the microphone, combined with the noise reduction structure, collects and cancels environmental noise, achieving high signal-to-noise ratio communication; in a quiet environment, the air conduction speaker unit provides rich low-frequency and high-fidelity sound quality experience. The entire machine coordinates battery power and output power through the power management module, extending the battery life.

[0045] In addition, the earphone automatically switches modes and optimizes sound quality based on wear state, environmental noise, and user volume preferences through intelligent algorithms, overcoming the technical bottlenecks of traditional bone conduction earphones' low-frequency deficiency and air conduction earphones' high-noise interference, demonstrating significant technological progress and substantial features.
