[0018] Please refer to Figures 1-4 The present application provides a technical solution: a bone conduction hearing aid earphone with a hanging structure, comprising an elastic band 1, one side of the elastic band 1 is provided with a hanging mechanism; One end of the elastic band 1 is fixedly connected with an elastic shell 401, the hanging mechanism comprises an earphone wire 304 and a hearing aid earphone 305, the earphone wire 304 is fixedly connected to the outer surface of the elastic shell 401, and the hearing aid earphone 305 is fixedly connected to the end of the earphone wire 304 away from the elastic shell 401. The hearing aid earphone 305 is a bone conduction earphone.

[0019] The surface of the elastic band 1 is coated with a silicone micro-convex texture coating, and the coating is added with antibacterial silver ion components, which can inhibit the growth of common bacteria such as escherichia coli and staphylococcus aureus, and reduce the risk of skin allergy caused by long-term wearing. The thickness of the coating is controlled to be 0.3-0.5mm, which not only maintains the soft touch of silicone, but also disperses local pressure through the micro-convex structure.

[0020] The inside of the hearing aid earphone 305 is provided with a noise reduction module 306. The noise reduction module 306 is a double-microphone active noise reduction module, and the hardware composition includes a feed-forward microphone installed on the outside of the bone conduction earphone 2, a feedback microphone installed close to the inside of the vibration unit, and a noise reduction chip integrated on the circuit board 402. The feed-forward microphone captures high-frequency noise in the environment, and the feedback microphone collects low-frequency noise generated by the resonance of the earphone vibration unit and the skull.

[0021] The noise reduction chip analyzes the noise signals of the two microphones in real time through the processor 404, generates a counteracting sound wave with the same amplitude and opposite frequency as the noise, and releases it through the bone conduction vibration unit, which cancels the noise interference at the auditory center level.

[0022] A microphone pickup hole with a diameter of 1mm is opened on the surface of the elastic shell 401, and a waterproof and breathable film is covered in the hole to ensure sound transmission and prevent sweat and dust from entering the internal circuit. The control switch 403 can add a noise reduction mode switching key to support strong noise reduction, weak noise reduction, and off three-grade adjustment to meet different scene needs. The noise reduction module cooperates with the original hearing aid function of the bone conduction earphone to amplify the target sound source while suppressing environmental noise and improve the clarity of the hearing aid.

[0023] The circuit board is fixedly installed inside the hearing aid earphone 305 and is the control and signal processing center of the entire earphone. The upper surface of the circuit board is fixedly installed with a permanent magnet and a voice coil, wherein the permanent magnet provides a constant magnetic field, and the voice coil is located in the magnetic field. When an electric signal passes through the voice coil, according to the principle of electromagnetic induction, the voice coil will vibrate in the magnetic field. The control switch and the outer magnetic ring are fixedly installed on one side of the circuit board, and the inner magnetic sheet is fixedly installed on the other side of the circuit board. The permanent magnet, the voice coil, the outer magnetic ring, and the inner magnetic sheet form a magnetic circuit system for converting an electric signal into a vibration signal. The control switch is electrically connected with the circuit board for controlling the on-off, volume adjustment, mode switching, and other working states of the earphone. The outer magnetic ring plays a role in guiding and concentrating the magnetic field, and together with the permanent magnet and the inner magnetic sheet, it constitutes a magnetic circuit system. The inner magnetic sheet further optimizes the magnetic circuit structure, enhances the stability and uniformity of the magnetic field, and thus improves the efficiency and accuracy of the voice coil vibration.

[0024] When the hearing aid earphone 305 is powered on and the control switch is turned on, an audio electric signal is transmitted to the circuit board through the earphone wire, and the circuit board processes the signal and sends it to the voice coil. The voice coil produces corresponding vibrations in the magnetic circuit system formed by the permanent magnet, the outer magnetic ring, and the inner magnetic sheet according to the change of the electric signal. The vibration is transmitted to the conductive earphone through the elastic shell, and the conductive earphone contacts the human skin and bones to conduct the vibration signal to the auditory nerve directly through solid as a medium, thereby realizing the transmission of sound and achieving the effect of auxiliary hearing.
