[0014] Compared with the prior art, this utility model provides an invisible ear-hook Bluetooth hearing aid with the following beneficial effects: 1. By pushing the slide upward, the elastic element is compressed, and the movement of the slide causes the compression wheel to move upward, so that it no longer presses the connecting wire. At this time, the connecting wire can be pulled upward to extend to a suitable length to adapt to the ear contours of different users, improve the wearing comfort and fit of the hearing aid, and thus expand the scope of use of the hearing aid.

[0015] 2. The silicone sleeve restores its original shape to fit the ear contour, which not only improves wearing comfort but also effectively fixes the speaker and prevents it from falling off. At the same time, the dustproof mesh can effectively block foreign objects such as earwax and dust from entering the speaker, so as to avoid affecting the sound quality or damaging the components.

[0016] 3. The protective pads contact the skin behind the ear, providing soft cushioning to avoid allergies or friction discomfort. In addition, the anti-slip strips increase friction with the skin, improving wearing stability and preventing the hearing aid from shifting. Attached Figure Description

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0025] Example 1: An invisible ear-hook Bluetooth hearing aid, please refer to... Figures 1-6The hearing aid includes a main body 1, buttons 2, a receiver 3, a speaker 4, a connector 5, a connecting cable 6, and a protective sleeve 11. Three buttons 2 are located on the left side of the main body 1. The connecting cable 6 is slidably mounted on the top of the main body 1. The other end of the protective sleeve 11 is fixedly connected to the connecting cable 6. The receiver 3 is plugged into the connector 5, and a speaker 4 is located on the front side of the receiver 3. The protective sleeve 11 covers the outside of the connecting cable 6. A support plate 7 is fixedly connected to the top inside the main body 1, and the connecting cable 6 is flush with the support plate 7. Slide plates 8 are slidably mounted on both the front and rear sides of the upper part of the main body 1, and the two slide plates 8 are used to fix the connection... A compression roller 9 is attached to the hearing aid body 1, which presses the connecting wire 6. An elastic element 10 connects the sliding plate 8 to the hearing aid body 1. An opening is provided on the protective cover 11. By bending the protective cover 11 outward along the opening, the connecting wire 6 can be exposed, making it easy to adjust the length of the connecting wire 6. Several reinforcing rings 12 are fixedly connected to the outside of the protective cover 11. The reinforcing rings 12 are used to limit the shape of the protective cover 11. A sealing ring 18 is fitted on the upper end of the plug 5 to ensure a tight connection between the receiver 3 and the plug 5 and to prevent sweat or dust from entering. A sweat pad 19 is provided on the right side of the hearing aid body 1 to absorb sweat and improve the comfort of wearing it for a long time.

[0026] When a hearing aid is needed, place the speaker 4 on the ear and move the hearing aid body 1 behind the ear, attaching it magnetically. After wearing, press button 2 to activate the hearing aid. The receiver 3 begins receiving external sound signals and converting them into electrical signals. The digital signal processor inside the hearing aid body 1 processes the electrical signals, performing noise reduction and gain adjustment to adapt to different hearing needs. The processed signal is output through the speaker 4, allowing the user to clearly hear surrounding sounds. Additionally, users can download a hearing aid tuning app to their mobile phone and connect via Bluetooth to tune the hearing aid. When adjusting the hearing aid parameters, if the size needs to be adjusted, push the slide plate 8 upwards. The elastic element 10 will be compressed accordingly. The movement of the slide plate 8 will cause the compression wheel 9 to move upwards, so that it no longer presses against the connecting cable 6. At this time, the connecting cable 6 can be pulled upwards to extend to a suitable length to adapt to the ear contours of different users, improve the wearing comfort and fit of the hearing aid, and thus expand the range of use of the hearing aid. After the adjustment is completed, release the slide plate 8. The elastic element 10 will return to its original state and push the slide plate 8 and the compression wheel 9 downwards to reset, re-pressing the connecting cable 6 to ensure that the cable is fixed and the signal transmission is stable.

[0027] Example 2: Based on Example 1, please refer to... Figures 1-3 A protective sleeve 13 is fixedly connected to the front of the receiver 3. The speaker 4 is located inside the protective sleeve 13. A silicone sleeve 14 is fitted on the front of the protective sleeve 13. A dustproof net 15 is embedded in the front of the silicone sleeve 14.

[0028] When the speaker 4 is worn on the ear, the silicone sleeve 14 is squeezed and deformed. After wearing, the silicone sleeve 14 returns to its original shape and fits the ear contour, which not only improves wearing comfort, but also effectively fixes the speaker 4 and prevents it from falling off. At the same time, the dustproof net 15 can effectively block foreign objects such as earwax and dust from entering the speaker 4, so as to avoid affecting the sound quality or damaging the components.

[0029] Please see Figure 4 A protective pad 16 is attached to the front of the hearing aid body 1. Several anti-slip strips 17 are fixedly connected to the front of the protective pad 16. The protective pad 16 is made of hydrogel, which is soft and hypoallergenic.

[0030] When the hearing aid body 1 is attached behind the ear, the protective pad 16 contacts the skin behind the ear, providing soft cushioning to avoid allergies or friction discomfort. In addition, the anti-slip strip 17 increases the friction with the skin, improves the wearing stability, and prevents the hearing aid from shifting.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
