DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1

[0027] Reference Figure 1-2 , which is the first embodiment of the present utility model, provides a hearing aid that is easy to maintain, including a support shell 101, an inner cavity of the support shell 101 is provided with a power supply mechanism 200, and the power supply mechanism 200 includes an embedded block 201 fixedly connected to the inner side surface of the support shell 101;

[0028] Furthermore, a circuit board 202 is plugged into the side surface of the embedded block 201 , and a quick-release mechanism 300 is provided in conjunction with the circuit board 202 .

[0029] Specifically, the power supply mechanism 200 and the supporting shell 101 are arranged in coordination so that the circuit board 202 can obtain electrical energy supply. The connection between the embedded block 201 and the circuit board 202 can help the circuit board 202 to be placed stably and reduce the shaking of the circuit board 202. At the same time, the coordination between the circuit board 202 and the quick-release mechanism 300 allows the button 103 to be flexibly disassembled on the surface of the circuit board 202, overcoming the disadvantage of the tin soldering method that is difficult to disassemble. At the same time, the flexible disassembly method can also avoid damage to the circuit board 202, making the hearing aid more durable.

[0030] Furthermore, the side of the embedded block 201 is fixedly connected to a docking base 302, the outer side of the docking base 302 is fixedly connected to a soldering seat 301, the end face of the soldering seat 301 is fixedly connected to the circuit board 202, and the quick-release mechanism 300 also includes an outer support plate 303, one side of the outer support plate 303 is plugged into the soldering seat 301.

[0031] Preferably, the fixed connection between the docking base 302 and the soldering seat 301 allows the button 103 to be placed stably, and the insertion of the outer support plate 303 and the soldering seat 301 allows the button 103 to be supported by the outer support plate 303, helping the button 103 to be more stable when disassembled.

[0032] It should be noted that the other side of the outer support plate 303 is fixedly connected to the plug-in plate 304 , and the end surface of the plug-in plate 304 is plugged into the circuit board 202 .

[0033] Afterwards, the matching arrangement of the plug board 304, the outer support board 303 and the button 103 allows the button 103 to be flexibly and quickly detached from the circuit board 202 through the plug-in action of the plug board 304. This method also avoids the impact of the difficulty in cleaning the solder joints after they are pulled out, and also facilitates the quick installation of the button 103.

[0034] Example 2

[0035] Reference Figure 2-3 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts for achieving a stable power supply effect of the annular battery 203.

[0036] Specifically, a protective frame 204 is fixedly connected to the inner cavity of the support shell 101 near one end, and the inner side surface of the protective frame 204 is plugged with the annular battery 203 , with a gap left between the annular battery 203 and the inner side surface of the embedded block 201 .

[0037] Furthermore, the protective frame 204 is plugged and fixed to the annular battery 203, making the power supply of the annular battery 203 more stable and balanced, while avoiding the leakage of electrolyte from the annular battery 203 due to collision. The button 103 can also be actively responded after being pressed, and the auxiliary hearing function of the hearing aid is better.

[0038] Preferably, the external mechanism 100 where the supporting shell 101 is located further includes a charging base 102 , which is fixedly connected to the end surface of the annular battery 203 , and the outer surface of the annular battery 203 is electrically connected to the circuit board 202 .

[0039] Among them, the fixed connection between the charging base 102 and the annular battery 203 allows the annular battery 203 to be quickly recharged through the charging base 102, while supplying electrical energy to the circuit board 202 and completing the action response of the pressing process with the button 103.

[0040] Example 3

[0041] Reference Figure 2-5 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts for achieving the hearing assistance effect of the hearing aid.

[0042] Specifically, an ear hook wire 104 is fixedly connected to the outer side surface of the supporting shell 101 , a receiver 105 is plugged into the end surface of the ear hook wire 104 , and an earplug 106 is clipped into the receiver 105 .

[0043] Furthermore, the connection between the ear hook wire 104 and the receiver 105 allows electrical energy to be transmitted to the receiver 105 through the ear hook wire 104, helping the receiver 105 to convert electrical signals into sound waves. The connection between the earplug 106 and the receiver 105 allows the converted sound waves to be transmitted to the eardrum of the hearing impaired through the earplug 106, helping the hearing impaired to hear normally.

[0044] Preferably, a button 103 is plugged into the top of the docking base 302 , the center of the button 103 is aligned with the center of the docking base 302 , and the side of the circuit board 202 is electrically connected to the ear hook wire 104 .

[0045] The button 103 is aligned with the center of the docking base 302 , so that the button 103 can be stably placed on the surface of the docking base 302 , the pressing area of the button 103 is increased, and the action response is more accurate.

[0046] Working principle: First, plug the charging base 102 into the power plug adapter to recharge the annular battery 203, and then the annular battery 203 stores energy and supplies it to the circuit board 202 through electrical connection. Then, place the button 103 on the upper surface of the docking base 302, plug one end of the ear hook wire 104 into the circuit board 202, and assemble and install the other end with the receiver 105, and then put the earplug 106 on the outer surface of the receiver 105 to assist the hearing of the hearing impaired; when the hearing aid needs to be disassembled, open the support shell 101, install and fix the outer support plate 303 and the plug-in plate 304, and flexibly plug the plug-in plate 304 into the side of the circuit board 202. Then, assemble and fix the outer support plate 303 and the soldering seat 301, which can be used for flexible disassembly of the button 103. The soldering seat 301 can also stably support the button 103 through the action of the plug-in plate 304.
