[0002] Hearing aids are often produced in a standardized way. Although this can improve production efficiency and reduce corporate costs, individual differences between users can cause discomfort when wearing the earphones. Standardized designs cannot adapt to the unique shape of each user's auricle, which in turn affects the comfort and sound quality of the hearing aids. For example, for users with special or irregular auricle shapes, traditional behind-the-ear hearing aids are often unstable to wear, and increase the risk of falling off during daily use.

[0003] Since hearing aids require multiple independent components and cables, the overall size and weight of the device will increase. It is also easy to cause the signal transmission path to be too long, generate electromagnetic interference, and affect the stability and performance of the system. Many existing headphones are generally made of plastic materials, which are easily affected by wear and impact in daily use, showing low durability and performance stability. Especially in humid environments or sweaty conditions, it poses a challenge to traditional hearing aids. Hearing aids are easily corroded and affect the performance and appearance of the device.

[0004] In the current earphone design, users cannot replace key components such as the housing of the moving iron unit, the first battery and the PCB assembly, which shortens the service life of the hearing aid earphone. At the same time, due to the irreversibility of the loss of the first battery and the non-modular design, the first battery cannot be replaced, which further leads to the generation of electronic waste.

[0005] In view of the problems of poor adaptability to the auricle, poor hearing aid effect and inconvenience in wearing existing hearing aid headphones in the prior art, it is necessary to optimize and improve the structure of the current hearing aid headphones to solve the existing technical problems. Summary of the invention

DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that although the description of these embodiments is used to help understand the present invention, it does not constitute a limitation of the present invention. The specific structures and functional details disclosed herein are only used to describe the embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments set forth herein.

[0028] According to a first aspect of the present invention, a 3D printed custom hearing aid headset is provided. Figures 1 to 6 One specific embodiment is shown.

[0029] See also Figures 1 to 6 As shown, the 3D printed customized hearing aid headset includes a body obtained by 3D printing, an electronic module 4 is provided on the body 2, an earplug 3 is provided at one end of the body 2, and an ear hook 1 is provided at the other end, and the ear hook 1 is formed into a shape that matches the auricle 51 so that it can be hung on the auricle 51; the electronic module 4 includes a first battery 41, a receiver 42, a microphone 43 and a controller 44, and the controller 44 is electrically connected to the first battery 41, and is communicatively connected to the receiver 42 and the microphone 43.

[0030] The working process of the 3D printed custom hearing aid headset is summarized as follows: the microphone 43 collects external sound signals, and the controller 44 processes and amplifies the received sound signals, and adjusts the volume and frequency response. The processed audio signal is transmitted to the user through the receiver 42 to help the user hear the surrounding sounds more clearly. The first battery 41 provides power support for the entire system to ensure long-term use.

[0031] Through the above technical solution, the body 2 is made by 3D printing technology, and can be customized according to the user's ear scanning data to ensure perfect fit with the auricle 51 and the ear canal. The ear hook 1 is formed into a shape that matches the auricle 51, and can be firmly hung on the auricle 51, providing good wearing comfort and stability. At the same time, before the body 2 is prepared by 3D printing technology, it is necessary to scan the user's ear, and the data obtained thereby is highly targeted, ensuring the best wearing comfort and stability.

[0032] It should be noted that 3D printing materials should be made of biocompatible, lightweight and strong materials, such as titanium alloy, ceramic, carbon fiber composite materials or high-performance resin materials to manufacture the shell, and be customized according to the shape of the user's ear canal, concha cavity and outer ear to ensure that the headphones fit perfectly and are comfortable to wear. 3D printing can achieve complex and delicate structures, optimize acoustic performance and internal space utilization. At the same time, the diverse material selection improves the durability and performance of the headphones to meet the needs of different users. The additive manufacturing method of 3D printing improves production efficiency, reduces material waste, supports small-batch diversified customization, reduces production costs and achieves environmentally friendly manufacturing. The integrated design makes the headphone structure compact and stable, which is convenient for future functional upgrades and maintenance.

[0033] In addition, 3D printing technology is a prior art, so this disclosure will not elaborate on it. However, it should be noted that the assembly accuracy should be ensured, especially the part in contact with the auricle 51 and the ear canal, to ensure the comfort and stability of the hearing aid earphone when worn.

[0034] In one embodiment provided by the present disclosure, a battery compartment is provided at the lower end of the ear hook 1, and a second battery 9 is detachably arranged in the battery compartment, so that the second battery 9 can be conveniently removed and installed from the battery compartment, which is convenient for replacement and charging. The second battery 9 is electrically connected to a power management module 6 arranged in the ear hook 1 to ensure power supply and data transmission. A male plug 7 is provided at the end of the ear hook 1, and a female plug 8 compatible with the male plug 7 is provided on the body 2; when the male plug 7 is inserted into the female plug 8, the second battery 9 can be electrically connected to the first battery 41, so that the first battery 41 in the body 2 is powered (charged) by the second battery 9, ensuring the normal operation of the entire machine.

[0035] Working principle: The user inserts the second battery 9 into the battery compartment, ensuring that it is secure and electrically connected to the power management module 6. When the male plug 7 is inserted into the female plug 8, the second battery 9 supplies power to the power management module 6 and other electronic components through electrical connection, and transmits necessary control signals. The power management module 6 manages the power output of the second battery 9, and coordinates the operation of components such as the microphone 43 and the receiver 42 to ensure efficient sound processing and transmission.

[0036] By setting a battery compartment at the lower end of the ear hook 1 and adopting a detachable second battery 9 and a plug connection design, the modularity and maintainability of the hearing aid headset can be significantly improved, the user's convenience and flexibility can be enhanced, thereby providing a stable power supply and signal transmission guarantee.

[0037] In the present disclosure, the positioning hole 81 and the positioning column 71 adopt an interference fit to achieve a tight fit between the male plug 7 and the female plug 8 .

[0038] In other embodiments, an external thread may be provided on the outer periphery of the positioning column 71 and an internal thread may be provided in the positioning hole 81, thereby achieving tight fixation of the male plug 7 and the female plug 8 through the threaded connection between the two.

[0039] In addition, as another embodiment, a card platform may be provided on the positioning column 71, and a card slot matched with the card platform may be provided on the female plug 8, thereby achieving a close fit between the card platform and the card slot.

At the same time, the flat design provides a larger contact area, enhances the stability of the ear hook 1 when placed, and reduces the risk of tipping or sliding.

[0046] In the present disclosure, the charging contacts 10 can be integrated on the flat bottom surface to ensure good contact with the external power source and improve charging efficiency.

[0047] In an embodiment provided by the present disclosure, a positioning column 71 is provided on the male plug 7, a limiting hole 72 is provided in the positioning column 71, and a first conductor 73 electrically connected to the second battery 9 is provided in the limiting hole 72; a positioning hole 81 adapted to the positioning column 71 is provided on the female plug 8 for inserting the female plug 8. The design of the positioning column 71 and the positioning hole 81 ensures the precise alignment of the male plug 7 and the female plug 8, and improves the reliability of the connection. A second conductor 82 connected to the first battery 41 is provided in the positioning hole 81, and the second conductor 82 is arranged opposite to the first conductor 73, ensuring that when the male plug 7 is inserted into the female plug 8, the first conductor 73 and the second conductor 82 can maintain good conductivity and contact stability, avoiding poor contact or circuit breakage. Stable connection and reliable electrical transmission enhance the overall user experience and reduce the inconvenience caused by connection problems.

[0048] Specifically, when the male plug 7 is inserted into the female plug 8, the positioning column 71 is inserted into the positioning hole 81 to ensure that the two are aligned and tightly matched. The first conductor 73 and the second conductor 82 are arranged relative to each other to ensure electrical connection, so that the second battery 9 can power the power management module 6 and other electronic components. The built-in charging management system monitors the charging status of the first battery 41 to prevent overcharging, over-discharging and other problems, and ensure safe charging.

[0049] By providing a positioning column 71 and a limiting hole 72 on the male plug 7, and providing a first conductor 73 electrically connected to the second battery 9 therein, and providing a matching positioning hole 81 and a second conductor 82 on the female plug 8, the electrical connection stability and reliability of the hearing aid earphone can be significantly improved. This design not only ensures accurate electrical connection, but also enhances the stability and protection performance of the connection, and is suitable for various usage scenarios.

[0050] Furthermore, a protruding stop ring 74 is provided on the outer periphery of the positioning column 71 , and a pressing cylinder 83 matched with the stop ring 74 is provided on the top of the positioning hole 81 to limit the movement range of the positioning column 71 and prevent over-insertion.

[0051] Specifically, when the male plug 7 is inserted into the female plug 8, the positioning column 71 is inserted into the positioning hole 81, and the stop ring 74 cooperates with the pressing cylinder 83 to limit the movement range of the positioning column 71 and ensure the insertion depth is consistent. Therefore, the cooperation between the stop ring 74 and the pressing cylinder 83 ensures that the insertion depth of the positioning column 71 is consistent, avoiding poor contact or looseness caused by too deep or too shallow insertion.

[0052] In a specific embodiment of the present disclosure, the ear hook 1 includes a connecting section 11, an ear hook section 12 and an extension section 13 connected in sequence. The connecting section 11 is detachably connected to the body 2 for easy maintenance and replacement. Specifically, the detachable connection can be achieved by means of a buckle, a thread or a magnetic attraction to ensure the stability and convenience of the connection.

[0053] The ear hook section 12 is made of flexible material, providing a soft touch and good fit, so that when the user wears the hearing aid headset, the ear hook 1 can better fit the auricle 51 of different shapes, increase friction and support, and improve wearing stability and comfort.

[0054] An earphone compartment is provided in the extension section 13, and a second battery 9 is arranged in the earphone compartment, thereby providing additional power support for the hearing aid earphone and extending the use time.

[0055] It should be noted that the earphone compartment adopts a sealed structure (such as a sealing gasket), so that sweat, rain, dust, etc. cannot enter the earphone compartment, thereby protecting the safety of the internal components in the earphone compartment.

[0056] In the present disclosure, the cross-sectional size of the extension section 13 gradually increases in the direction away from the body 2, forming a gradient shape, so that the contact area of ​​the ear hook 1 on the auricle 51 is larger, the friction and support force are increased, and the possibility of slipping is reduced. At the same time, the gradient design makes the ear hook 1 fit the natural curve of the auricle 51, which can reduce the discomfort when worn for a long time and improve the comfort of the user.

[0057] In addition, based on the gradual design of the ear hook 1, the volume behind the ear is increased, which can increase the accommodation space, thereby installing, for example, the power management module 6 and the first battery 41.

[0058] In the present disclosure, the ear hook section 12 is made of silicone material. In this way, on the one hand, the ear hook section 12 can better fit the natural curve of the auricle 51, provide a soft touch and disperse pressure, and reduce discomfort when worn for a long time. At the same time, the friction between the ear hook section 12 and the auricle 51 can be increased, providing better support and fixing effects, and reducing the possibility of slipping. In this way, the wearing comfort and stability of the hearing aid earphone are improved, which is particularly suitable for users who need to wear it for a long time, ensuring that it is stable and reliable every time it is worn.

[0059] Specifically, the flexible material selected for the ear hook section 12 is medical grade silicone.
