Description

Technical Field

[0001] The utility model relates to the technical field of hearing aid equipment, in particular to a hearing aid. Background Art

[0002] Currently, most of the battery covers of hearing aids on the market are fixed by a snap-on structure. Since the batteries of hearing aids need to be replaced regularly, the battery cover needs to be opened and closed frequently, which will result in a short snap-on life of the battery cover. In addition, the user needs to use a certain amount of force to open the battery cover, which makes it very inconvenient to open and close the battery cover. In addition, most of the users are elderly people, and it is difficult for the users to control their strength. As a result, the hearing aids are often damaged due to excessive force, which seriously affects the user experience. Utility Model Content

[0003] In view of this, the utility model provides a hearing aid to solve the problem that the battery cover of the hearing aid in the prior art is inconvenient to open and close and easy to be damaged.

[0004] The utility model provides a hearing aid, comprising:

[0005] Hearing aid body;

[0006] A battery cover, one end of which is hinged to the hearing aid body and the other end of which is provided with a snap-on structure;

[0007] An elastic switch, the middle part of which is hinged on the hearing aid body, and the first end of which is connected to the hearing aid body through an elastic member, and the second end of which is provided with a snap-fit ​​structure;

[0008] The elastic switch has a locked state and an unlocked state:

[0009] When the elastic switch is in a locked state, the snap-fit ​​structure is snapped with the snap-fit ​​matching structure, and the elastic member can limit the relative movement between the snap-fit ​​matching structure and the snap-fit ​​structure;

[0010] When the elastic switch is in an unlocked state, the first end of the elastic switch, under the action of external pressure, drives the snap-fitting structure at the second end of the elastic switch to move in a direction away from the snap-fitting structure.

[0011] Beneficial effect: through the elastic switch, when you want to open the battery cover, you can press the first end of the elastic switch so that the snap-fitting structure at the other end of the elastic switch can move in the direction away from the snap-fitting structure, so that the snap-fitting structure can get rid of the constraint of the snap-fitting structure, and then you can open the battery cover more conveniently and quickly to replace the battery, and at the same time it can effectively avoid the problem of forcefully opening the cover, which may easily cause structural damage; when you want to close the battery cover, you can directly press the battery cover to easily snap the battery cover closed, and after the snap-fitting structure and the snap-fitting structure are snapped together, the elastic member can limit the relative movement of the snap-fitting structure and the snap-fitting structure to prevent the two from being decoupled, so that the snap-fitting structure and the snap-fitting structure can maintain a stable mating state. The hearing aid provided in the present application realizes the opening and closing of the battery cover by adopting the above-mentioned elastic switch in cooperation with the battery cover. The entire opening and closing cover operation is quick and convenient, which can not only meet the requirements of stable fixation of the battery cover, but also take into account the convenience of opening and closing the cover, thereby improving the service life of the hearing aid and the user experience, achieving the technical effect of convenience in replacing batteries, and effectively solving the problems of inconvenient opening and closing and easy damage of the battery cover in the prior art.

[0012] In an optional embodiment, the snap-fit ​​structure includes a first snap buckle, and the snap-fitting structure includes a second snap buckle.

[0013] Beneficial effects: The snap-fit ​​structure and the snap-fit ​​matching structure adopt a snap-fit ​​structure, which can achieve stable snap-fit ​​while having a relatively simple structure and being easy to process and shape.

[0014] In an optional embodiment, the second buckle includes a guide wall and a clamping wall arranged at a set angle, and the guide wall is located between the clamping wall and the battery cover;

[0015] The guide wall is constructed as an inclined surface or a curved surface, and is used to guide the first buckle to enter the elastic switch and hook onto the clamping wall.

[0016] Beneficial effect: By setting the above-mentioned guide wall, the first buckle can slide into the elastic switch more easily and cooperate with the second buckle under the guidance of the inclined surface or curved surface, avoiding the problem that the first buckle and the second buckle may be deformed or damaged due to the user pressing the battery cover forcefully.

[0017] In an optional embodiment, the hearing aid body includes a housing and a support portion fixedly disposed in the housing;

[0018] Flexible switches include:

[0019] The switch body has a receiving portion at the second end thereof, one end of the elastic member is abutted and limited in the receiving portion, and the other end of the elastic member is abutted on the supporting portion.

[0020] Beneficial effect: The support portion is provided to facilitate the abutment and cooperation between the hearing aid body and the elastic member. The accommodating portion is provided at the second end of the switch body, so that one end of the elastic member is accommodated and limited in the accommodating portion, and the other end abuts on the support portion, which can effectively reduce the risk of the elastic member detaching from the switch body and improve the stability of the cooperation between the switch body and the elastic member.

[0021] In an optional embodiment, the elastic member is a spring, and a limiting column is fixedly provided on the support portion; one end of the spring is abutted and limited in the accommodating portion, and the other end is sleeved on the limiting column and abuts against the support portion.

[0022] Beneficial effect: The elastic member adopts the structure of a spring. Since the spring is easy to deform and has high elasticity, it is easier and more labor-saving to open the battery cover. When the battery cover is buckled, the stability of the entire structure is higher and it is not easy to get unhooked. By setting a limit column on the support part and the spring sleeve on the limit column, the risk of the elastic member detaching from the support part can be further reduced, so that the support part and the elastic member can cooperate more stably and reliably.

[0023] In an optional implementation, the switch body is further provided with an axial hole suitable for being rotatably connected to the hearing aid body, and the axial hole is located between the accommodating portion and the snap-fit ​​structure.

[0024] Beneficial effects: An axial hole is opened in the middle of the switch body, and a corresponding connecting hole is opened on the hearing aid body. The hinge shaft can pass through the connecting hole on the hearing aid body and the axial hole on the switch body respectively to realize the hinge connection between the elastic switch and the hearing aid body. In this way, the elastic switch can be quickly disassembled and assembled by disassembling and assembling the hinge shaft, making the disassembly and assembly of the elastic switch more flexible and convenient.

[0025] In an optional embodiment, the elastic switch further includes:

[0026] The limiting part is fixedly arranged on a side wall of the switch body close to the supporting part, and the limiting part is suitable for abutting and matching with the supporting part to limit the engagement depth of the snap-fit ​​structure and the snap-fit ​​matching structure.

[0027] Beneficial effect: through the setting of the limit part, when the push switch is snapped together by the spring, the limit part will abut and cooperate with the support part to form a snapping limit, so that the switch body has an extreme position in the counterclockwise direction. On the one hand, it can avoid the problem of difficulty in opening the cover due to excessive snapping of the snap-fit ​​structure and the snap-fitting structure. When the snap-fit ​​structure and the snap-fitting structure are snapped together too much, the snap-fitting degree is large, and the pressing force required to open the cover is also greater, and the user experience will become worse. On the other hand, it can also effectively avoid the problem that the switch body rotates too much counterclockwise and the accommodating part also rotates, which will cause the spring to be pushed out of the accommodating part.

[0028] In an optional implementation, the limiting portion is located between a hinge point and a snap-fit ​​structure between the elastic switch and the hearing aid body.

[0029] Beneficial effect: By arranging the limiting part and the snap-fitting structure on one side of the hinge point and arranging the accommodating part on the other side of the hinge point, the limiting part can achieve a better limiting effect.

[0030] In an optional implementation, a protruding distance of the limiting portion relative to the switch body is greater than a protruding distance of the accommodating portion relative to the switch body.

[0031] Beneficial effect: By adopting the above-mentioned size design, it is possible to effectively avoid the limiting portion being too short and failing to achieve an effective limiting effect.

[0032] In an optional implementation, the switch body is a plate-shaped structure, and the limiting portion is a convex rib fixedly disposed on the switch body.

[0033] In an optional embodiment, a groove capable of accommodating the snap-fit ​​structure is formed between the limiting portion and the snap-fit ​​structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0051] Combine the following Figures 1 to 9 , describing an embodiment of the utility model.

[0052] According to an embodiment of the utility model, the utility model provides a hearing aid, including a hearing aid body 1, a battery cover 2, and an elastic switch 3, wherein one end of the battery cover 2 is hinged on the hearing aid body 1, and the other end is provided with a snap-fit ​​structure; the middle part of the elastic switch 3 is hinged on the hearing aid body 1, and the first end is connected to the hearing aid body 1 through an elastic member 4, and the second end is provided with a snap-fit ​​structure.

[0053] Furthermore, the elastic switch 3 has a locked state and an unlocked state: when the elastic switch 3 is in the locked state, the snap-fit ​​structure is engaged with the snap-fit ​​structure, and the elastic member 4 can limit the relative movement of the snap-fit ​​structure and the snap-fit ​​structure to prevent the two from being disengaged; when the elastic switch 3 is in the unlocked state, the first end of the elastic switch 3, under the action of external pressure, will drive the snap-fit ​​structure at the second end of the elastic switch 3 to move away from the snap-fit ​​structure, so that the snap-fit ​​structure and the snap-fit ​​structure are free from constraint.

[0054] In the above embodiment, by setting the elastic switch 3, when the battery cover 2 is to be opened, the first end of the elastic switch 3 can be pressed so that the snap-fitting structure at the other end of the elastic switch 3 can be moved in a direction away from the snap-fitting structure, so that the snap-fitting structure can be freed from the constraint of the snap-fitting structure, and the battery cover 2 can be opened more conveniently and quickly to replace the battery 5, and at the same time, the problem of forceful opening of the cover, which may easily cause structural damage, can be effectively avoided; when the battery cover 2 is to be closed, the battery cover 2 can be directly pressed to easily snap the battery cover 2 closed, and after the snap-fitting structure and the snap-fitting structure are snapped together, the elastic member can limit the relative movement of the snap-fitting structure and the snap-fitting structure to prevent the two from being decoupled, so that the snap-fitting structure and the snap-fitting structure can maintain a stable mating state. The hearing aid provided in the present application realizes the opening and closing of the battery cover 2 by adopting the above-mentioned elastic switch 3 and the battery cover 2. The entire opening and closing cover operation is quick and convenient, which can not only meet the requirements of stable fixation of the battery cover 2, but also take into account the convenience of opening and closing the cover, thereby improving the service life of the hearing aid and the user experience, achieving the technical effect of convenience in replacing the battery 5, and effectively solving the problem of inconvenient opening and closing and easy damage of the battery cover 2 in the prior art.

[0055] Specifically, the lower end of the battery cover 2 is hinged on the hearing aid body 1, and the upper end is fixedly connected to the hearing aid body 1. A battery compartment is provided in the battery cover 2, and a battery 5 is installed in the battery compartment. The elastic switch 3 is similar to a lever, and the middle part is hinged on the hearing aid body 1. When the battery cover 2 is to be buckled, the upper end of the battery cover 2 is pressed so that the snap-fit ​​structure on the upper end of the battery cover 2 is hooked with the snap-fit ​​matching structure on the elastic switch 3. After the snap-fit ​​structure is hooked with the snap-fit ​​matching structure, under the action of the elastic member 4, the second end of the elastic switch 3 moves in a direction close to the snap-fit ​​structure, so that the snap-fit ​​structure and the snap-fit ​​matching structure can maintain a stable matching state, thereby effectively fixing the battery cover 2; when the battery cover 2 is to be opened, the user presses the first end of the elastic switch 3 downward, and under the action of the lever, the second end of the elastic switch 3 moves in a direction away from the snap-fit ​​structure, so that the snap-fit ​​structure and the snap-fit ​​matching structure can be out of contact, so that the battery cover 2 is opened. In this embodiment, an elastic switch 3 that can be opened and closed by pressing is arranged between the hearing aid body 1 and the battery cover 2, so that the battery cover 2 can be opened and closed more easily, thereby improving the convenience of the product.

[0056] In some embodiments, the snap-fit ​​structure includes a first snap-fit ​​21 , and the snap-fitting structure includes a second snap-fit ​​31 .

[0057] In the above embodiments, the snap-fit ​​structure and the snap-fit ​​matching structure adopt a snap-fit ​​structure, which can achieve stable snap-fit ​​while having a relatively simple structure and being easy to process and shape.

[0058] Specifically, the first buckle 21 is fixedly arranged on the inner wall of the battery cover 2. The first buckle 21 includes a main body and a hook portion. The hook portion is fixedly arranged at one end of the main body away from the battery cover 2. The hook portion is located on the side of the main body facing the elastic switch 3. The hook portion is suitable for hooking with the second buckle 31.

[0059] Preferably, the end surface of the hook portion is designed with an arc surface, so that the first buckle 21 can slide into the second buckle 31 more easily, reducing the risk of mechanical jamming when the battery cover 2 is buckled into the hearing aid body 1.

[0060] Of course, in other alternative implementations, the snap-fit ​​structure and the snap-fit ​​matching structure may also adopt structural forms such as claws, clamping platforms, grooves, etc., which are not limited in this embodiment.

[0061] In some embodiments, in combination Figure 2 , Figure 3As shown, the second buckle 31 includes a guide wall 311 and a clamping wall 312 arranged at a set angle, and the guide wall 311 is located between the clamping wall 312 and the battery cover 2; the guide wall 311 is constructed as an inclined surface or a curved surface, and the guide wall 311 is used to guide the first buckle 21 into the elastic switch 3 and hook onto the clamping wall 312.

[0062] In the above embodiment, by setting the above-mentioned guide wall 311, the first buckle 21 can slide into the elastic switch 3 more easily and cooperate with the second buckle 31 under the guidance of the inclined surface or curved surface, thereby avoiding the problem that the user presses the battery cover 2 forcefully, which may cause the first buckle 21 and the second buckle 31 to be deformed or damaged.

[0063] Preferably, in this embodiment, the guide wall 311 adopts a curved structure, so that the movement of the battery cover 2 when buckled in will be smoother and more stable.

[0064] Specifically, the side wall of the second buckle 31 facing the battery cover 2 is configured as a curved surface to form a guide wall 311, and the side wall of the second buckle 31 facing away from the battery cover 2 is configured as a vertical flat wall surface to form a clamping wall 312. By adopting the design of the guide wall 311 and the vertically arranged clamping wall 312, the second buckle 31 is configured as a one-way buckle, which facilitates its engagement with the first buckle 21 and is not easy to be unhooked.

[0065] In some embodiments, the hearing aid body 1 includes a shell 11 and a support portion 12 fixedly disposed in the shell 11; the elastic switch 3 includes a switch body 30, a second end of the switch body 30 is provided with a receiving portion 32, one end of the elastic member 4 abuts and is limited in the receiving portion 32, and the other end abuts on the support portion 12.

[0066] In the above embodiment, the support portion 12 is provided to facilitate the abutment and cooperation between the hearing aid body 1 and the elastic member 4. By providing the accommodating portion 32 at the second end of the switch body 30, one end of the elastic member 4 is accommodated and limited in the accommodating portion 32, and the other end abuts on the support portion 12, which can effectively reduce the risk of the elastic member 4 detaching from the switch body 30 and improve the stability of the cooperation between the switch body 30 and the elastic member 4.

[0067] Specifically, the support portion 12 is a support rib or a support plate fixedly disposed in the housing 11 , and a spring groove is provided in the accommodating portion 32 , and the end of the elastic member 4 is limited in the spring groove.

[0068] In some embodiments, the elastic member 4 is a spring, and a limiting column 121 is fixedly provided on the support portion 12 ; one end of the spring is abutted and limited in the accommodating portion 32 , and the other end is sleeved on the limiting column 121 and abuts against the support portion 12 .

[0069] In the above embodiment, the elastic member 4 adopts the structure of a spring. Since the spring is easy to deform and has high elasticity, it is easier and more labor-saving to open the battery cover 2. When the battery cover 2 is buckled, the stability of the entire structure is higher and it is not easy to get off. By setting a limit column 121 on the support part 12 and the spring sleeved on the limit column 121, the risk of the elastic member 4 being separated from the support part 12 can be further reduced, so that the support part 12 and the elastic member 4 can be matched more stably and reliably.

[0070] Specifically, the limiting column 121 is fixedly arranged on a side wall of the support portion 12 close to the elastic switch 3, and the position of the limiting column 121 is opposite to the position of the accommodating portion 32. Under normal conditions, the spring applies a force to the second end of the switch body 30 to move away from the support portion 12, and under the action of the middle lever, the first end of the switch body 30 moves toward the direction close to the clamping structure, so that the clamping matching structure of the first end can be stably clamped and maintained on the clamping structure.

[0071] In some embodiments, in combination Figure 1 , Figure 2 , Figure 8 , Fig. 9 As shown, the switch body 30 is also provided with an axial hole 301 suitable for rotationally connecting with the hearing aid body 1 , and the axial hole 301 is located between the accommodating portion 32 and the snap-fit ​​structure.

[0072] In the above embodiment, an axial hole 301 is provided in the middle of the switch body 30, and a connecting hole is correspondingly provided on the hearing aid body 1. The hinge shaft 34 can pass through the connecting hole on the hearing aid body 1 and the axial hole 301 on the switch body 30 respectively to realize the hinge connection between the elastic switch 3 and the hearing aid body 1. In this way, the elastic switch 3 can be quickly disassembled and assembled by disassembling and assembling the hinge shaft 34, making the disassembly and assembly of the elastic switch 3 more flexible and convenient.

[0073] Of course, in other alternative embodiments, rotating shafts may be fixedly provided on both sides of the switch body 30 to achieve hinged connection between the switch body 30 and the hearing aid body 1 .

[0074] In some embodiments, the elastic switch 3 further includes a limit portion 33, which is fixedly disposed on a side wall of the switch body 30 close to the support portion 12, and is suitable for abutting and cooperating with the support portion 12 to limit the engagement depth between the snap-fit ​​structure and the snap-fitting structure.

[0075] In the above embodiment, by setting the limit portion 33, when the push switch is snapped under the action of the spring, the limit portion 33 will abut and cooperate with the support portion 12 to form a snapping limit, so that the switch body 30 has an extreme position in the counterclockwise direction. On the one hand, it can avoid the problem of difficulty in opening the cover due to excessive snapping of the snap-fitting structure and the snap-fitting structure. When the snap-fitting structure and the snap-fitting structure are snapped too much, the snap-fitting degree is large, and the pressing force required when opening the cover is also greater, and the user experience will be worse. On the other hand, it can also effectively avoid the problem that the switch body 30 rotates too much counterclockwise and the accommodating portion 32 also rotates, which will cause the spring to be pushed out of the accommodating portion 32.

[0076] Specifically, the limiting portion 33 is a protruding structure disposed on one side of the switch body 30 close to the supporting portion 12 , and the limiting portion 33 may be in the form of a convex column, a convex rib, a boss, or the like.

[0077] In some embodiments, the limiting portion 33 is located between the hinge point and the snap-fit ​​structure between the elastic switch 3 and the hearing aid body 1 .

[0078] In the above embodiment, the limiting portion 33 and the snap-fitting structure are arranged on one side of the hinge point, and the accommodating portion 32 is arranged on the other side of the hinge point, so that the limiting portion 33 can achieve a better limiting effect.

[0079] In some embodiments, a protruding distance of the limiting portion 33 relative to the switch body 30 is greater than a protruding distance of the accommodating portion 32 relative to the switch body 30 .

[0080] In the above embodiment, by adopting the above dimension design, it is possible to effectively avoid the limiting portion 33 being too short and failing to achieve an effective limiting effect.

[0081] The hearing aid provided in this embodiment makes the buckle cooperation between the battery cover 2 and the hearing aid body 1 more flexible and convenient by adding an elastic switch 3 between the battery cover 2 and the hearing aid body 1. The elastic switch 3 also uses a two-way restriction so that it has limit constraints in both the clockwise and counterclockwise directions. While reducing the number of parts, it solves the problem that the battery cover 2 of the hearing aid is inconvenient to remove the battery 5 due to the buckle fixation problem, and the problem that the buckle life of the battery cover 2 is short due to the inappropriate force to open the cover.

[0082] In some specific embodiments, the switch body 30 is a plate-shaped structure, and the limiting portion 33 is a convex rib fixedly disposed on the switch body 30. The end of the convex rib is provided with an abutting plane suitable for abutting and cooperating with the support portion 12.

[0083] Preferably, the switch body 30 , the snap-fit ​​structure, the limiting portion 33 , and the accommodating portion 32 are integrally formed.

[0084] In this embodiment, the limit portion 33 is a protruding structure having a certain protruding length. Because the elastic switch 3 is rotatably connected to the hearing aid body 1 through the hinge shaft 34, the elastic switch 3 can move clockwise or counterclockwise. Figure 4 As shown, the elastic switch 3 will be in a counterclockwise force state. When it moves counterclockwise under force, the limiter 33 will press against the support part 12, thereby playing a limiting role. Because when the buckle is too much, the degree of buckle fit will be greater, and the degree of pressing required will also be greater, and the user experience will be worse. If there is no restriction on this direction, the elastic switch 3 will rotate too much counterclockwise, and the accommodating part 32 will also rotate, so that the spring will fly out due to the rotation of the fixed structure.

[0085] Furthermore, a groove for accommodating the snap-fit ​​structure is formed between the limiting portion 33 and the snap-fit ​​structure. Through the above-formed groove, when the battery cover 2 is buckled onto the hearing aid body 1, the snap-fit ​​structure can extend into the groove, ensuring that the snap-fit ​​structure and the snap-fit ​​structure can be stably matched.

[0086] The specific structure and working principle of the hearing aid in this embodiment are introduced below with reference to the accompanying drawings.

[0087] like Fig. 9 As shown, the main structure of the hearing aid includes a hearing aid body 1, a battery cover 2 and an elastic switch 3. The hearing aid body 1 is mainly a behind-the-ear hearing aid. The elastic switch 3 mainly includes a switch body 30, an axis hole 301, a snap-fit ​​structure, a limit portion 33 and an accommodating portion 32 for accommodating the elastic member 4. The main functions of the snap-fit ​​structure (the second snap 31) are as follows: Figure 7 As shown, when the first buckle 21 on the battery cover 2 enters and engages in the clockwise direction, under the guidance of the curved surface of the second buckle 31, the first buckle 21 on the battery cover 2 will enter the switch body 30 and engage with the second buckle 31 (as shown in FIG. Figure 3 , Figure 4 As shown in the figure, the battery cover 2 is locked. If the battery cover 2 needs to be opened, pressure needs to be applied to the upper position of the accommodating portion 32 of the switch body 30, so that the elastic switch 3 rotates clockwise under the action of the shaft, thereby releasing the buckle state and enabling the battery cover 2 buckle to open the cover counterclockwise. The role of the limiting portion 33: Under the action of the spring pressure, the elastic switch 3 will be in a counterclockwise force state. The role of the limiting portion 33 is to constrain the counterclockwise rotation position of the elastic switch 3. The role of the accommodating portion 32 is to fix the position of the spring. The accommodating portion 32 works together with the limiting column 121 on the support portion 12 to constrain the spring, so that it can telescope and move in the space between the support portion 12 and the accommodating portion 32.

[0088] Furthermore, if Figure 2 , Figure 3As shown, when the battery cover 2 is in the buckled state, the elastic switch 3 will be driven to rotate counterclockwise due to the compression force of the spring. At this time, the second buckle 31 will buckle with the first buckle 21 on the battery cover 2 to fix the battery cover 2. The buckled state is as shown in FIG. Figure 4 As shown, while the spring is limited by the accommodation portion 32 of the elastic switch 3 and the limiting column 121, the limiting portion 33 fixes the buckled state of the battery cover 2 and meets the strength requirements of the two buckles without damaging the buckles.

[0089] Further, the process of opening the cover is as follows: Figures 5 to 7 As shown, by applying a certain pressure to the position above the accommodation portion 32 of the elastic switch 3, the spring is compressed and deformed, so that the elastic switch 3 rotates clockwise. In this rotation direction, the first buckle 21 is not restricted, and the battery cover 2 can be opened to replace the battery 5. When the battery cover 2 needs to be closed, since the second buckle 31 is a one-way buckle, it has a guiding function when fastened, and the spring is compressed by the reaction force to open the elastic switch 3. When the first buckle 21 is in place, you can let go so that the elastic switch 3 returns to the fastened state under the action of the spring.

[0090] Furthermore, if Figure 7 As shown, when the first buckle 21 enters the engagement in the clockwise direction, under the curved surface guiding action of the second buckle 31, the first buckle 21 will enter the elastic switch 3 and engage with the second buckle 31 of the elastic switch 3 (as shown in FIG. Figure 3 , Figure 4 As shown), the battery cover 2 is locked. If the battery cover 2 needs to be opened, pressure needs to be applied to the upper position of the accommodating portion 32 at the first end of the switch body 30, so that the switch body 30 rotates clockwise under the action of the hinge shaft 34, thereby releasing the buckled state, and the first buckle 21 can realize the cover opening operation counterclockwise.

[0091] The hearing aid provided in this embodiment makes opening and closing the battery cover 2 more convenient by adding an elastic switch 3 between the battery cover 2 and the hearing aid body 1. The battery cover 2 can be easily opened by simply applying force to the elastic switch 3.
