Description

Technical Field

[0001] This utility model relates to the field of bone conduction hearing aid technology, and in particular to a magnetically connected bone conduction hearing aid. Background Technology

[0002] In the field of hearing aids, bone conduction hearing aids are widely used for people with special hearing impairments such as ear canal malformations and otitis media due to their advantages of not needing to be inserted into the external auditory canal and being more comfortable to wear. As users' requirements for device portability and ease of use increase, magnetically connected bone conduction hearing aids have become a key focus of research and development.

[0003] Currently, bone conduction hearing aids generally use a structure with built-in, non-replaceable batteries or a casing secured with screws for battery maintenance. Some common designs use small button batteries or lithium polymer batteries, connected to the circuit board via soldering or plugging. The battery compartment is usually located inside the main body of the device, requiring users to use tools to remove casing screws or pry open clips to access the battery. Some products use miniature connectors or flexible contacts to establish contact between the battery and the main circuitry, relying on mechanical pressure or a mounting bracket to hold the battery in place and ensure stable power supply.

[0004] However, the battery replacement process in the existing technology is quite cumbersome. Users need to disassemble multiple fixed parts and even use special tools. Not only are the operation steps complicated, but frequent disassembly and assembly can also lead to wear and tear on parts or a decrease in connection reliability. In particular, for hearing-impaired users with limited mobility or hand dexterity, the actual experience of replacing batteries is poor, which affects the overall ease of use and user satisfaction of bone conduction hearing aids. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a magnetically connected bone conduction hearing aid, which aims to improve the convenience of replacing the battery in traditional hearing aids by requiring the disassembly of multiple parts and making the operation cumbersome.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a magnetically connected bone conduction hearing aid, including a shell, a battery slidably connected inside the shell, an arc-shaped column fixedly connected to the outer wall of the shell, and a snap-fit ​​assembly provided inside the arc-shaped column; The buckle assembly includes a hollow column, the outer wall of which is fixedly connected to the inside of an arc-shaped column. A first spring is provided inside the hollow column, one end of which is fixedly connected to the inner wall of the hollow column, and the other end of which is fixedly connected to a retaining ball. The side wall of the retaining ball is slidably connected to the side wall of the battery.

[0007] As a further description of the above technical solution: A fixed post is slidably connected to one end of the outer shell, and a connecting sleeve is fixedly connected to one end of the fixed post.

[0008] As a further description of the above technical solution: One end of the connecting sleeve is fixedly connected to a connecting wire, and the other end of the connecting wire is fixedly connected to a receiver.

[0009] As a further description of the above technical solution: The inner wall of the outer shell is fixedly connected to a support column, and the support column has a sliding groove inside.

[0010] As a further description of the above technical solution: A clamping plate is fixedly connected to the outer wall of the fixed column, and the side wall of the clamping plate is slidably connected to the inner wall of the support column.

[0011] As a further description of the above technical solution: A second spring is provided on the inner wall of the outer casing. One end of the second spring is fixedly connected to the inner wall of the outer casing, and the other end of the second spring is fixedly connected to a retaining ring.

[0012] As a further description of the above technical solution: The outer wall of the retaining ring is slidably connected to the inside of the outer shell, and the side wall of the retaining ring is slidably connected to the side wall of the card plate.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the battery is pulled out, and the force applied to the battery will move the locking ball on the side wall. At the same time, the force applied to the locking ball will compress the first spring on the side wall, achieving the effect of modular battery replacement. This solves the problem of traditional hearing aids requiring the disassembly of multiple parts and cumbersome operation when replacing batteries, and improves the convenience of replacing batteries in bone conduction hearing aids.

[0014] 2. In this utility model, pressing the connecting sleeve drives the fixing post to slide on the inner wall of the outer shell. Then, the movement of the fixing post will move the retaining ring on the side wall. At the same time, the movement of the retaining ring will compress the second spring. Then, the fixing post rotates, causing its side wall to slide out of the inner wall of the support post, and the side wall of the card plate to disengage from the support post. This achieves the effect of quickly replacing the connecting wire, solving the problem of difficult and time-consuming replacement after damage to the connecting wire of traditional hearing aids, and improving the convenience of replacing the components of bone conduction hearing aids.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Reference Figures 1-3 This utility model provides an embodiment of a magnetically connected bone conduction hearing aid, including a shell 1. The shell 1 is used to house core components such as a battery 2 and a support column 15, and at the same time provides a fixed base for the arc-shaped column 3, thereby realizing the integrated installation of each component, ensuring the stability of the overall structure of the hearing aid, and preventing internal parts from falling or shifting due to the lack of a fixed carrier. The battery 2 is slidably connected inside the shell 1. The battery 2 is used to provide power for the operation of the hearing aid and to power electrical components such as the receiver 4, thereby ensuring that the hearing aid can normally process and transmit sound signals and ensure that the user can hear normally. Its function of powering electronic products is common knowledge and will not be described in detail here. The arc-shaped column 3 is fixedly connected to the outer wall of the shell 1, and a buckle assembly is provided inside the arc-shaped column 3. The buckle assembly includes a hollow column 6, the outer wall of which is fixedly connected to the inside of the arc-shaped column 3. A first spring 8 is provided inside the hollow column 6. One end of the first spring 8 is fixedly connected to the inner wall of the hollow column 6, and the other end of the first spring 8 is fixedly connected to a retaining ball 7. The retaining ball 7 is used to engage with the corresponding slot on the side wall of the battery 2 to limit and fix the battery 2, thereby preventing the battery 2 from sliding freely inside the outer shell 1, ensuring the stability of the connection between the battery 2 and the internal circuit, and avoiding power outages or malfunctions of the hearing aid due to displacement of the battery 2. The side wall of the retaining ball 7 is slidably connected to the side wall of the battery 2.

[0019] Reference Figure 4 and Figure 5One end of the outer casing 1 is slidably connected to a fixing post 13. The fixing post 13 is used to connect the connecting sleeve 14 and the locking plate 12, transmitting the pressing and rotating force of the connecting sleeve 14 to the locking plate 12, so that the locking plate 12 can complete the corresponding movement synchronously, ensuring that the operation command can be effectively transmitted to the locking structure, realizing the loading and unloading control of the components. One end of the fixing post 13 is fixedly connected to the connecting sleeve 14, and one end of the connecting sleeve 14 is fixedly connected to the connecting wire 5. The connecting wire 5 is used to connect the connecting sleeve 14 and the receiver 4, realizing the signal and power transmission between the two, thereby ensuring that the receiver 4 can receive the electrical signal from the main body of the hearing aid, ensuring the normal operation of the sound output function. One end of the connecting wire 5 is fixedly connected to the receiver 4, which is used to convert the processed electrical signal into a sound signal and transmit it to the user's auditory system, thereby helping the hearing-impaired user perceive sound. It acts as an aid. The core sound-generating component of the hearing device, used for sound signal conversion and output, is existing technology and will not be described in detail here. A support column 15 is fixedly connected to the inner wall of the outer shell 1. A sliding groove 11 is opened inside the support column 15. A retaining plate 12 is fixedly connected to the outer wall of the fixed column 13. The side wall of the retaining plate 12 is slidably connected to the inner wall of the support column 15. A second spring 9 is provided on the inner wall of the outer shell 1. One end of the second spring 9 is fixedly connected to the inner wall of the outer shell 1, and the other end of the second spring 9 is fixedly connected to a retaining ring 10. The retaining ring 10 is used to transmit the elastic force of the second spring 9 to the fixed column 13, and at the same time, it slides in contact with the side wall of the retaining plate 12. Thus, under the action of the second spring 9, the fixed column 13 is driven to pop out or reset, ensuring that the movement of the fixed column 13 can stably respond to the operation command. The outer wall of the retaining ring 10 is slidably connected to the inside of the outer shell 1, and the side wall of the retaining ring 10 is slidably connected to the side wall of the retaining plate 12.

[0020] Working principle: During battery 2 replacement, when battery 2 needs to be removed, pull battery 2 outward from the outer casing 1. The side wall of battery 2 will exert an outward pushing force on the retaining ball 7. Since the retaining ball 7 is slidably connected to the side wall of battery 2, it will move into the hollow column 6 after being subjected to force, while squeezing the first spring 8 inside the hollow column 6, so that the first spring 8 is in a compressed state. As the retaining ball 7 is fully retracted into the hollow column 6, battery 2 loses its clamping restriction and can be directly pulled out from the outer casing 1 to complete the disassembly. When installing a new battery 2, push battery 2 into the outer casing 1. The side wall of battery 2 will squeeze the retaining ball 7 again and compress the first spring 8. When battery 2 is pushed to the preset position, the first spring 8 restores its elastic deformation, pushing the retaining ball 7 to pop out and lock into the corresponding slot on the side wall of battery 2, realizing the quick fixation of battery 2. The whole process does not require disassembly of any external parts. During the replacement of the connecting cable 5 and receiver 4, press the connecting sleeve 14. The connecting sleeve 14 drives the fixing post 13 to slide into the housing 1. The fixing post 13 pushes the retaining ring 10 to move synchronously. The retaining ring 10 compresses the second spring 9 on the inner wall of the housing 1, causing it to contract. When the locking plate 12 on the fixing post 13 is fully inserted into the slide groove 11 of the support post 15, rotate the connecting sleeve 14, causing the fixing post 13 and the locking plate 12 to rotate, disengaging the locking plate 12 from the inner wall of the support post 15. At this time, release the connecting sleeve 14. The second spring 9 returns to its original shape and pushes the retaining ring 10. The retaining ring 10 causes the fixing post 13 and the connecting sleeve 14 to pop outward, allowing the connecting sleeve 14, hollow post 6, and receiver 4 to be removed for replacement. When installing new components, reverse the above steps. The elasticity of the second spring 9 and the engagement of the locking plate 12 with the support post 15 ensure a stable connection of the components.
