[0038] Combined Figure 1 and Figure 2 , the present utility model provides an embodiment, a hearing aid, which includes a main body 1 and a cover body 2. The main body 1 is provided with a groove 11, and a frequency modulation knob 12 is arranged in the groove 11. The frequency modulation knob 12 is used to adjust the frequency band of the hearing aid. The cover body 2 is detachably connected to the groove 11. Wherein, the hearing aid has a use state and a maintenance state. In the use state, the cover body 2 is connected to the groove 11 and covers the frequency modulation knob 12. In the maintenance state, the cover body 2 is separated from the groove 11 and the frequency modulation knob 12 is exposed.

[0039] In some embodiments, the structure of the main body 1 is a box-like structure with six faces. The corners between the faces of the main body 1 are rounded for convenient user grip. One of the faces is provided with a groove 11, and a frequency modulation knob 12 is arranged in the groove 11. There are two frequency modulation knobs 12, which are spaced apart and arranged at the bottom of the groove 11. The cover body 2 is a cover-like structure. The length of the cover body 2 is the same as or slightly less than the length of the groove 11, the width of the cover body 2 is the same as or slightly less than the width of the groove 11, and the thickness of the cover body 2 is the same as the depth of the groove 11. When the cover body 2 is connected in the groove 11, the surface of the entire hearing aid is flat, preventing the cover body 2 from being easily disassembled by external force.

[0040] In some embodiments, the frequency modulation knob 12 is recessed at the bottom of the groove 11, and the cover body can directly cover the bottom of the groove 11.

[0041] In other embodiments, the frequency modulation knob 12 protrudes from the bottom of the groove 11, and a concave hole is provided at the corresponding position of the cover body. When the cover body covers the bottom of the groove 11, the concave hole can accommodate the frequency modulation knob 12.

[0042] In the above technical solution, the hearing aid includes a main body 1 and a cover body 2. The main body 1 is provided with a frequency modulation knob 12 for frequency modulation. Among them, the main body 1 is provided with a groove 11, and the frequency modulation knob 12 is arranged in the groove 11. The cover body 2 is detachably connected to the groove 11. This enables the hearing aid to have two usage states and maintenance states. Before the user initially uses the hearing aid, the hearing aid is adjusted to the maintenance state, and the cover body 2 is detached from the groove 11 of the main body 1, exposing the frequency modulation knob 12 in the groove 11. Then, the frequency modulation knob 12 is adjusted to make the frequency of the hearing aid adapt to the user. Then, the hearing aid is adjusted to the usage state, that is, the cover body 2 is connected to the groove 11, so that the cover body 2 covers the frequency modulation knob 12. And because the cover body 2 is connected in the groove 11, the cover body 2 is not easily dropped, further protecting the frequency modulation knob 12 of the main body 1, making the frequency modulation knob 12 in an isolated state when not in use, improving the durability of the hearing aid, and also ensuring the usage effect of the hearing aid.

[0043] Combined with Figure 2 In one embodiment of the present utility model, the groove 11 includes a main groove 111 and a side groove 112. The main groove 111 and the side groove 112 are communicated with each other. The bottom of the main groove 111 and the bottom of the side groove 112 are arranged at an angle. The frequency modulation knob 12 is arranged at the bottom of the main groove 111. The cover body 2 includes a main shell 21 and a side shell 22 connected to each other. The main shell 21 is adapted to the main groove 111, and the side shell 22 is adapted to the side groove 112.

[0044] In some embodiments, a groove 11 is provided on one surface of the main body 1. It can be understood that the six surfaces of the box-shaped main body 1 are perpendicular to each other. Therefore, the groove 11 extends along the length direction to three surfaces, forming the side groove 112 and the main groove 111. And the two side grooves 112 are located on both sides of the main groove 111, that is, a layout of side groove 112, main groove 111, and side groove 112 is formed. The bottom of the side groove 112 and the bottom of the main groove 111 are perpendicular. The cover body 2 is also divided into a main shell 21 and a side shell 22. The two side shells 22 are connected to both sides of the main shell 21, and the side shell 22 and the main shell 21 are perpendicular to each other. In the usage state, the main shell 21 is connected in the main groove 111, and the two side shells 22 are connected in the two side grooves 112 on both sides.

[0045] In the above technical solution, the cover body 2 is detachably connected to three surfaces of the main body 1, and both the main shell 21 and the side shell 22 are located in the groove 11, so that in the usage state, the connection between the cover body 2 and the main body 1 is more stable. And the cover body 2 with two side shells 22 also makes it convenient for the user to hold when detaching or installing the cover body 2.

[0046] Combined with Figure 2 In one embodiment of the present utility model, the cover body 2 is magnetically connected to the main body 1 so that the cover body 2 is detachably connected to the main body 1.

[0047] In some embodiments, a magnet 23 is provided in the groove 11 of the main body 1, and the cover 2 is made of a magnetizable metal material, so that the cover 2 is detachably connected in the groove 11. Alternatively, a magnetizable metal part or structure is provided in the groove 11 of the main body 1, and the cover 2 is provided with a magnet 23, which also makes the cover 2 detachably connected in the groove 11.

[0048] In the above technical solution, the cover 2 and the main body 1 are connected by the magnet 23, which is convenient for the user to install or remove the cover 2 and improves convenience.

[0049] Combined Figure 2 , an embodiment of the present utility model is proposed. One of the side shells 22 and the side grooves 112 is provided with a magnet 23, and the other is provided with a magnetic part. The cover 2 is magnetically connected to the cover 2 through the magnet 23 and the magnetic part.

[0050] In some embodiments, magnets 23 are provided on one side of the two side shells 22 facing the groove 11, and the material of the groove 11 is a magnetizable metal material. In other embodiments, grooves are further provided in the two side grooves 112, and the sizes of the magnets 23 of the two side shells 22 are adapted to the grooves, so that the cover 2 can be guided when magnetized.

[0051] In the above technical solution, the cover 2 is magnetically attracted to the groove 11 by the magnets 23 on both sides, so that the force on the cover 2 is more uniform, and the magnetic connection between the cover 2 and the main body 1 is more stable. Moreover, when the user holds the cover 2, the user can hold the two side shells 22 on both sides of the cover 2, which are exactly located at the positions where the magnets 23 are located, facilitating the user to apply force to remove the cover 2.

[0052] Combined Figure 2 , an embodiment of the present utility model is proposed. The main body 1 includes a housing and a main board. The housing is provided with the groove 11, and the housing is provided with an installation cavity. The main board is arranged in the installation cavity, and the tuning knob 12 is electrically connected to the main board.

[0053] In some embodiments, the housing includes an upper shell 101 and a lower shell 102. The upper shell 101 is provided with the groove 11, and the lower shell 102 and the upper shell 101 are connected together to form an installation cavity. It can be understood that the groove 11 has four groove walls. The groove 11 of the upper shell 101 forms the upper and lower two groove walls, and when the lower shell 102 is connected to the upper shell 101, the edge of the lower shell 102 forms the groove wall of the groove 11.

[0054] Such a setting simplifies the structure of the upper shell 101 and facilitates the processing of the upper and lower shells 102. The circuit board is installed on the upper shell 101 or the lower shell 102.

[0055] In the above technical solution, the housing uses a split setting, which is convenient for installing the circuit board.

[0056] Combined with Figure 2 In one embodiment proposed by the present utility model, the hearing aid is further provided with a distress call device, and the distress call device includes a speaker and a distress call button 13. The speaker is disposed in the installation cavity and electrically connected to the main board. The distress call button 13 is disposed on the housing, and the distress call button 13 is electrically connected to the main board.

[0057] In some embodiments, the hearing aid is further provided with a distress call button 13. The area of the distress call button 13 is the area that can be pressed by the thumb, and it is set in the center of the main body 1. Speakers are also provided around the main body 1. The distress call button 13 and the speakers are both connected to the main board. Optionally, the speaker can also be a buzzer.

[0058] In the above technical solution, when the user encounters an emergency, the user can press the distress call button 13 to control the operation of the speaker or buzzer to make a sound to attract the attention of others. And when the main body 1 is connected to a headphone or a wireless headphone, pressing the distress call button 13 will not make a sound through the headphone, but will make a sound through the speaker or buzzer.

[0059] Combined with Figure 2 In one embodiment proposed by the present utility model, the distress call button 13 is disposed in the groove 11, and the cover body 2 is provided with a through hole 24. The shape of the through hole 24 is adapted to the distress call button 13. In the use state, the distress call button 13 is located in the through hole 24.

[0060] In some embodiments, the distress call button 13 is set in the center of the groove 11, and the outer shape of the distress call button 13 is square. There is also a through hole 24 in the middle of the cover body 2 that is adapted to the outer shape of the distress call button 13. When the cover body 2 is connected to the main body 1, the distress call button 13 is located in the middle of the through hole 24 and is framed by the cover body 2. And the height of the distress call button 13 is higher than that of the cover body 2 so that the button extends about 1 mm out of the surface of the hearing aid, avoiding the difficulty for the user to press the distress call button 13.

[0061] In some other embodiments, the colors of the main body 1, the cover body 2 and the distress call button 13 are set to different colors respectively. Such a setting makes the contrast color of the hearing aid obvious, which is convenient for the user to find the position of the distress call button 13 when in a daze.

[0062] Through this embodiment, the cover body 2 not only protects the frequency modulation knob 12, but also the split structure is convenient for processing and can be set to different colors, having a certain aesthetic or prompting effect.

[0063] Combined with Figure 2, an embodiment of the present utility model is proposed. The distance between the pore wall of the through hole 24 and the side surface of the distress call button 13 is 0.5 mm to 1.0 mm. At the junction of the pore wall of the through hole 24 and the surface of the cover body 2 facing the groove 11, there is an annular boss 25. An annular groove 113 is provided around the distress call button 13, and the annular boss is arranged corresponding to the annular groove 113.

[0064] In the above technical solution, there is a certain gap between the distress call button 13 and the through hole 24, which is convenient for the cover body 2 to be disassembled with a certain redundancy without affecting the movement of the cover body 2, and also avoids knocking the distress call button 13 when the cover body 2 is disassembled. When the hearing aid is in use, the annular boss 25 is embedded in the annular groove 113, so that some dust accumulates at most in the annular groove 113 and will not enter the frequency modulation knob 12.
