Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a wireless bone conduction anti-drop hearing aid. Background Technology

[0002] The need for sound perception among people with hearing impairments has driven the continuous development of hearing aids. Wireless bone conduction anti-drop hearing aids, as a targeted solution, are mainly aimed at people with hearing impairments who have sensitive ear canals, damaged eardrums, or who need to use them in sports scenarios. The core of these hearing aids is to bypass the dependence of traditional air conduction on the ear canal and eardrum by using bone conduction technology, converting sound signals into bone vibrations that are transmitted to the inner ear. At the same time, combined with an anti-drop structure design, the device is ensured to be worn stably during daily activities or sports, meeting the user's dual needs for clear sound perception and device stability.

[0003] Traditional bone conduction hearing aids typically consist of a vibrating sound generator, an ear hook, a built-in battery, and a microphone. When in operation, the microphone captures external sounds, which are then processed by an internal chip and transmitted to the vibrating sound generator. The vibrating sound generator fits against the temporal bone and other parts of the body, converting the sound signal into mechanical vibrations, which are then transmitted through the skull to the auditory nerve in the inner ear.

[0004] Existing hearing aids have significant structural design flaws. Traditional bone conduction hearing aids typically feature a fixed, integrated design for the sound unit, power supply, and connection structure. When a single component malfunctions, it cannot be disassembled and replaced individually; the entire device must be sent to a professional repair facility. This not only results in long repair cycles and high costs but also causes users to lose hearing support during the repair period. Furthermore, the integrated structure limits the device's functional expansion. If users need to replace batteries with different lifespans or pickup components with different sensitivities, they must purchase the entire device again, preventing them from flexibly matching components to their needs. This leads to resource waste and increased operating costs. Therefore, a wireless bone conduction anti-drop hearing aid is proposed to address these issues. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a wireless bone conduction anti-drop hearing aid, aiming to improve the problems of existing technologies where faulty components cannot be replaced individually and battery anxiety exists. To achieve the above objectives, this utility model adopts the following technical solution: A wireless bone conduction anti-drop hearing aid includes a sound-generating device, a press-lock slot on one side of the sound-generating device, a press-lock slidably connected to the press-lock slot, an earphone rod fixedly connected to the press-lock, a lock button abutting against the outside of the press-lock, and four pickup holes on the outside of the earphone rod. As a further description of the above technical solution: The bottom of the earphone connecting rod is provided with a press-locking slot, the inner wall of the press-locking slot is slidably connected to the outside of the press-locking, and a replaceable battery is fixedly connected to the bottom of the press-locking; As a further description of the above technical solution: The inside of the press-lock buckle is provided with a brass slot, and a brass column is fixedly connected to the top of the press-lock buckle. As a further description of the above technical solution: A charging slot is provided on one side of the earphone connecting rod, and a magnetic charger is slidably connected to the inner wall of the charging slot. A brass slot is provided on one side of the magnetic charger. As a further description of the above technical solution: A hidden emergency power supply is fixedly connected inside the earphone rod, and a magnetic base is fixedly connected to one side of the hidden emergency power supply. As a further description of the above technical solution: The magnetic charger has a portable battery charging compartment on one side, and a battery slot is provided inside the portable battery charging compartment. As a further description of the above technical solution: A brass pillar is fixedly connected to one side of the magnetic base, and the brass pillar is slidably connected inside the brass slot. As a further description of the above technical solution: The inner wall of the battery slot is provided with a power supply slot, and the inner wall of the power supply slot is slidably connected to the outer wall of the replaceable battery.

[0006] This utility model has the following beneficial effects: 1. In this utility model, the modular connection of the sound-generating device, the headphone rod and the replaceable battery are realized through the meshing structure of the press-lock buckle and the press-lock buckle slot. Each component can be quickly disassembled and assembled by pressing the lock buckle button. When a single component has a problem, there is no need to repair or replace the whole equipment. Only the faulty component needs to be replaced, which significantly reduces the maintenance cost and cycle.

[0007] 2. In this utility model, the hidden emergency power supply fixed inside the earphone rod and the replaceable battery form a dual power supply guarantee. When the replaceable battery is depleted or a contact problem occurs, the hidden emergency power supply can automatically switch power supply to avoid sudden interruption of hearing assistance function and effectively solve the emergency need of forgetting to bring spare batteries when going out.

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.

[0011] Reference Figures 1-3 One embodiment of this utility model is a wireless bone conduction anti-drop hearing aid, which includes a sound-generating device. The sound-generating device 1 has a press-lock slot 7 on one side. The function of the sound-generating device 1 is to convert the audio signal into a bone conduction vibration signal, and then transmit the vibration to the inner ear auditory nerve through contact with the human skeleton, so that the user can perceive the sound. A press-lock latch 5 is slidably connected to the press-lock slot 7. The press-lock latch 5 is fixedly connected to the headphone rod 16. The headphone rod 16 is connected to the sound-generating device through the press-lock latch. A latch button 17 is abutted against the outside of the press-lock latch 5. Four pickup holes 2 are opened on the outside of the headphone rod 16. The pickup holes 2 are used to capture sound signals from the external environment and provide the original signal source for subsequent sound processing and bone conduction transmission. A press-lock latch slot 7 is opened at the bottom of the headphone rod 16. The press-lock latch slot 7 is slidably connected to the outside of the press-lock latch 5. A replaceable battery 3 is fixedly connected to the press-lock latch 5. A brass slot 12 is set inside the press-lock latch slot 7. A brass pillar 6 is fixedly connected to the top of the press-lock latch 5.

[0012] Reference Figures 4-6 The headphone stem 16 has a charging slot 4 on one side, and a magnetic charger 10 is slidably connected to the charging slot 4. The magnetic charger 10 is a charging component that enables a stable connection between the device and the power source, balancing charging efficiency and ease of use. The magnetic charger 10 has a brass slot 12 on one side. A hidden emergency power supply 8 is fixedly connected inside the headphone stem 16. The hidden emergency power supply 8 serves as an emergency power source. When the replaceable battery 3 runs out of power or has a contact problem, it can quickly switch power supply to prevent the device from suddenly losing power and becoming unusable. It is especially suitable for emergencies such as forgetting to bring a spare battery. A magnetic base 9 is fixedly connected to one side of the hidden emergency power supply 8. A portable battery charging compartment 13 is set on one side of the magnetic charger 10. A battery slot 14 is opened inside the portable battery charging compartment 13. A power supply slot 15 is opened on the inner wall of the battery slot 14. The replaceable battery 3 is slidably connected to the inner wall of the power supply slot 15.

[0013] Working principle: First, after the device is started, the pickup hole 2 captures external sound signals, processes them, and transmits them to the sound-generating device 1. The sound-generating device 1 converts the audio signals into bone conduction vibration signals, which are transmitted to the auditory nerve in the inner ear through contact with the human skeleton, thus completing sound perception. In terms of structural connection, the sound-generating device 1 is fixed by the engagement of the press-locking slot 7 with the press-locking buckle 5, and can be quickly disassembled and assembled with the lock button 17; the earphone connecting rod 16 serves as a carrier, with one end connected to the press-locking buckle 5, and the bottom connected to the replaceable battery 3 through the same lock structure to provide the main power supply for the device; the brass slot 12 inside the press-locking slot 7 fits tightly with the brass pillar 6 on the top of the press-locking buckle 5 to ensure circuit conduction and ensure stable power supply and signal transmission.

[0014] The device's battery life and charging system operate collaboratively through multiple structures. When charging is needed, the magnetic charger 10 slides into the headphone rod 16 along the charging slot 4. Its brass slot 12 on one side connects to the brass pillar 6 of the magnetic base 9, allowing the hidden emergency power supply 8 to replenish power. The portable battery charging case 13 stores the replaceable battery 3 through its internal battery slot 14 and charges the backup battery using the power supply slot 15, meeting battery life needs when out and about. When the replaceable battery 3 is low on power, the hidden emergency power supply 8 automatically switches power to prevent device interruption. The overall design, through modular locking, a brass conductive structure, and magnetic charging, ensures stability against drops while achieving efficient sound transmission and flexible battery life management.
