[0030] In the terms of the present utility model, the words such as "first" and "second" are only for descriptive purposes and cannot be construed as indicating or implying relative importance, nor as limiting the order of precedence

[0031] A hearing aid facilitating installation provided by the present utility model includes a housing 11, a control component 13 located at one end of the housing 11, and a sound outlet component 14 located at the other end of the housing 11. The sound outlet component 14 includes a sound outlet nozzle 143 and an air conduction speaker 141 detachably connected to the sound outlet nozzle 143 and electrically connected to the control component 13. The sound outlet nozzle 143 is made of soft rubber material. A hollow connecting column 1431 for extending into the housing 11 is provided at one end of the sound outlet nozzle 143 close to the housing 11. The air conduction speaker 141 is connected in the connecting column 1431. A first through hole 1121 is provided at one end of the housing 11 close to the sound outlet nozzle 143. The diameter of the first through hole 1121 is smaller than the diameter of the connecting column 1431. The sound outlet nozzle 143 is press-fitted into the first through hole 1121. The housing 11 is used to install the control component 13 and the sound outlet component 14. The control component 13 is used to control the sound outlet component 14. The air conduction speaker 141 is used to transmit sound. The sound outlet nozzle 143 is used to fix the air conduction speaker 141. When installing the sound outlet component 14, first, connect the air conduction speaker 141 in the connecting column 1431 to make the air conduction speaker 141 and the sound outlet nozzle 143 connected as a whole, and extend the air conduction speaker 141 into the first through hole 1121. When the connecting column 1431 contacts the first through hole 1121, the housing 11 squeezes the sound outlet nozzle 143. Since the diameter of the connecting column 1431 is larger than the diameter of the first through hole 1121 and the sound outlet nozzle 143 is made of soft rubber material, the connecting column 1431 deforms and is press-fitted into the first through hole 1121, thereby fixing the sound outlet nozzle 143 in the housing 11. Finally, fix the control component 13 at the other end of the housing 11. When installing the hearing aid, the assembly difficulty is reduced, the assembly efficiency is effectively improved, and thus the production efficiency can be effectively improved

[0032] The sound output component 14 further includes a connecting pipe 142. The bone conduction speaker 141 is connected to one end of the connecting pipe 142, and the other end of the connecting pipe 142 is connected inside the connecting column 1431. The bone conduction speaker 141 is connected inside the connecting column 1431 through the connecting pipe 142, which can effectively extend the length of the bone conduction speaker 141 and facilitate the electrical connection between the bone conduction speaker 141 and the control component 13.

[0033] A dust-proof plug 144 is further provided at one end of the sound outlet nozzle 143 away from the connecting column 1431. The dust-proof plug 144 is used to prevent dust or sundries from entering the connecting column 1431, which can effectively prevent the bone conduction speaker 141 from being blocked, thereby effectively ensuring the sound output of the bone conduction speaker 141.

[0034] A plurality of limiting grooves 1122 for preventing the sound outlet nozzle 143 from rotating are further provided in the first through hole 1121. The limiting grooves 1122 are used to limit the rotation of the sound outlet nozzle 143. When the connecting column 1431 is deformed and connected inside the first through hole 1121, the sound outlet nozzle 143 simultaneously fills the limiting grooves 1122, thereby effectively preventing the sound outlet nozzle 143 from rotating on the housing 11.

[0035] The sound outlet nozzle 143 is further provided with a skirt 1432. The diameter of the skirt 1432 is equal to the diameter of the housing 11 at the end close to the sound outlet nozzle 143. The skirt 1432 is used to prevent the housing 11 from being exposed, and can effectively prevent the housing 11 from causing potential harm to the hand during assembly.

[0036] An earphone 12 detachably connected to the sound outlet nozzle 143 is further provided at one end of the sound outlet nozzle 143 away from the connecting column 1431. The earphone 12 is made of soft rubber material and is used to contact the ear. When the earphone 12 is connected in the ear, the ear squeezes the earphone 12, and the earphone 12 deforms, thereby fixing the earphone 12 in the ear and preventing the hearing aid from separating from the ear.

[0037] An annular and concave fixing groove 1433 is further provided on the periphery of the sound outlet nozzle 143. A hollow fixing column connected to the sound outlet nozzle 143 is provided inside the earphone 12. A fixing protrusion clamped in the fixing groove 1433 is provided inside the fixing column. The fixing protrusion inside the fixing column is clamped in the limiting groove 1122 of the sound outlet nozzle 143, and the fixing groove 1433 limits the fixing protrusion to prevent the earphone 12 from separating from the sound outlet nozzle 143.

[0038] The housing 11 includes a top cover 111 and a lower case 112. The control component 13 is connected inside the top cover 111. A battery 1122 electrically connected to the control component 13 is provided inside the lower case 112. The lower case 112 is used to install the battery 1122 and the sound output component 14, and the top cover 111 is used to install the control component 13. When the top cover 111 and the lower case 112 are sealed, they are used to seal the control component 13 and the battery 1122 inside the housing 11.

[0039] A step 1121 for limiting the battery 1122 is provided inside the lower shell 112. The step 1121 is used to limit the battery 1122 to prevent the battery 1122 from moving within the housing 11.

[0040] Working principle:

[0041] When installing the hearing aid, first, the sound output end of the air conduction speaker 141 is sleeved inside the connecting pipe 142, and the connecting pipe 142 is extended into the connecting column 1431 of the sound output nozzle 143. Further, the dust-proof plug 144 is extended into one end of the sound output nozzle 143 away from the connecting pipe 142. Finally, the fixing protrusion of the earcup 12 is snap-fitted into the fixing groove 1433 of the sound output nozzle 143, forming an integral body of the sound output nozzle 143, the connecting pipe 142, the air conduction speaker 141, and the earcup 12. The formed integral air conduction speaker 141 is extended into the housing 11 through the first through hole 1121 of the housing 11. Since the sound output nozzle 143 is made of soft rubber material and the diameter of the connecting column 1431 is larger than the diameter of the first through hole 1121, when the connecting column 1431 of the sound output nozzle 143 is extended into the first through hole 1121, the connecting column 1431 is deformed and interference-fitted inside the first through hole 1121, and a limiting groove 1122 is provided inside the connecting column 1431. The deformed connecting column 1431 is filled into the limiting groove 1122 to prevent the sound output nozzle 143 from rotating inside the housing 11. Further, the air conduction speaker 141 connected inside the housing 11 is electrically connected to the control component 13, and the battery 1122 is placed inside the lower shell 112. Finally, the control component 13 is placed on one side of the battery 1122 and sealed by the top cover 111, sealing the control component 13 and the battery 1122 inside the housing 11. Through the above structure, the difficulty of assembling the hearing aid can be effectively reduced, the efficiency of assembling the hearing aid can be accelerated, and thus the production capacity of the hearing aid can be improved.

[0042] The hearing aid that is easy to install in this preferred embodiment connects the air conduction speaker inside the sound output nozzle, and extends the air conduction speaker connected inside the sound output nozzle into the housing through the first through hole. The diameter of the connecting column is larger than the diameter of the first through hole. When the connecting column is connected to the first through hole, the connecting column is deformed and interference-fitted inside the first through hole. Extending the air conduction speaker from outside the housing into the housing reduces the difficulty of assembly, effectively improves the assembly efficiency, and improves the production capacity.

[0043] In summary, although the present utility model has been disclosed above with the preferred embodiments, the above preferred embodiments are not intended to limit the present utility model. Those of ordinary skill in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the scope defined by the claims.
