Description

Technical Field

[0001] This utility model relates to the field of hearing aid technology, specifically a hearing aid with a vent structure. Background Technology

[0002] Occlusion effect is a common problem in hearing aid use. When the hearing aid earmold is inserted into the ear canal, the user will clearly feel that their voice is louder, muffled, and accompanied by an echo. The core reason is that the ear canal is physically blocked by the earmold, preventing sound and pressure from being transmitted normally within the ear canal. To alleviate these problems, audiologists or manufacturers usually create a vent inside the earmold. This vent allows some low-frequency sounds and air to escape from the ear canal, effectively reducing the pressure within the ear canal and thus mitigating the occlusion effect.

[0003] In existing hearing aids with vent structures, the vent diameter is designed in different sizes to suit the different hearing needs of hearing-impaired patients. For example, a smaller diameter vent provides moderate low-frequency attenuation, which can alleviate the occlusion effect to some extent and is suitable for mild to moderate hearing-impaired patients who require some low-frequency compensation. A larger diameter vent provides extremely strong low-frequency attenuation, which can effectively eliminate the occlusion effect and is suitable for hearing-impaired patients with high-frequency hearing loss but normal or near-normal low-frequency hearing. However, the vent diameter of existing hearing aids is fixed once it is designed. When hearing-impaired patients need to switch to hearing aids with different vent diameters due to changes in usage scenarios, they can only achieve this by frequently changing hearing aids with different vent diameters, which brings many inconveniences to the daily use of hearing-impaired patients. Utility Model Content

[0004] To address the aforementioned shortcomings, this invention proposes a hearing aid with a vent structure. The aim is to solve the problem that the diameter of the vent in existing hearing aids is fixed once it is formed. When hearing-impaired patients need to switch between hearing aids with different vent diameters due to changes in usage scenarios, they can only frequently change hearing aids with different vent diameters, which brings many inconveniences to their daily use.

[0005] To achieve this goal, the present invention adopts the following technical solution: A hearing aid with a vent structure includes a housing, a controller, a flexible tube, a wire, an earmold assembly, a venting tube, and an isolating element. The controller is disposed inside the housing. One end of the flexible tube is connected to the housing, and the other end of the flexible tube is connected to the earmold assembly. The wire passes through the interior of the flexible tube, and its two ends are electrically connected to the controller and the earmold assembly, respectively. The earmold assembly is used to amplify sound signals of different frequencies. A vent is formed inside the earmold assembly, extending in a left-right direction. The venting tube is detachably installed inside the vent, and its diameter is smaller than that of the vent. The isolating element is sleeved on the outer side of the venting tube. When the venting tube is installed inside the vent, the isolating element is used to seal the gap space formed between the inner wall of the vent and the outer wall of the vent.

[0006] Preferably, the barrier is a cotton sleeve, a rubber sleeve, or a silicone sleeve.

[0007] Preferably, the diameter of the vent hole is... The diameter of the vent pipe is 2.0mm~2.5mm. The thickness is 0.5mm to 1.0mm.

[0008] Preferably, the earmold assembly includes an eardrum body and an ear cap, the ear cap having an opening; the ear cap is fitted onto one end of the eardrum body, the vent is located inside the eardrum body, and the vent is connected to the opening on the ear cap.

[0009] Preferably, the ear mold assembly further includes a heart rate sensor, and an installation groove is provided on the outer side of the eardrum body. The heart rate sensor is installed in the installation groove and is communicatively connected to the controller.

[0010] Preferably, the outer surface of the eardrum body is provided with a plurality of positioning protrusions, and the plurality of positioning protrusions are evenly distributed along the periphery of the eardrum body.

[0011] The technical solution provided by this utility model can include the following beneficial effects: This design incorporates an internal ventilation hole in the earmold assembly, into which a detachable ventilation tube fitted with a blocking element is installed, creating a flexibly adjustable ventilation structure that effectively alleviates the occlusion effect. When hearing-impaired patients need to switch between different hearing aids due to changing usage scenarios, there's no need to frequently replace hearing aids with ventilation holes of different diameters. The diameter of the ear canal ventilation channel can be flexibly changed simply by installing or removing the ventilation tube: when a larger ear canal ventilation channel diameter is required, the ventilation tube can be removed or omitted, and the diameter of the ventilation hole can be used directly as the ear canal ventilation channel diameter, suitable for mild to moderate hearing-impaired patients requiring some low-frequency compensation; when a smaller ear canal ventilation channel diameter is required, the ventilation tube can be installed, and its diameter can be used as the ear canal ventilation channel diameter, suitable for hearing-impaired patients with high-frequency hearing loss but normal or near-normal low-frequency hearing. This design effectively avoids the inconvenience of frequent hearing aid replacements, improving the daily convenience for hearing-impaired patients. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "assembly," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] A hearing aid with a ventilation hole structure includes a housing 1, a controller (not shown in the figure), a hose 2, a wire 3, an earmold assembly 4, a ventilation tube 5, and a blocking component 6; The controller is located inside the housing 1. One end of the flexible tube 2 is connected to the housing 1, and the other end of the flexible tube 2 is connected to the earmold assembly 4. The wire 3 passes through the interior of the flexible tube 2, and its two ends are electrically connected to the controller and the earmold assembly 4, respectively. The earmold assembly 4 is used to amplify sound signals of different frequencies. The ear mold assembly 4 has a ventilation hole 40 inside, which extends in the left and right direction. The ventilation tube 5 is detachably installed in the ventilation hole 40, and the diameter of the ventilation tube 5 is smaller than the diameter of the ventilation hole 40. The barrier 6 is sleeved on the outer side of the vent pipe 5. When the vent pipe 5 is installed in the vent hole 40, the barrier 6 is used to block the gap space 7 formed between the inner wall of the vent hole 40 and the outer wall of the vent pipe 5.

[0018] This solution provides a hearing aid with a vent structure. In this embodiment, for example... Figure 1-3 As shown, the hearing aid also includes a microphone (not shown in the figure), which is installed on the outer side of the housing 1 and electrically connected to the controller. During operation, the microphone first accurately receives external sound signals and transmits them to the controller in real time. After processing the sound signals, the controller transmits the processed signals to the earmold assembly 4 via the wire 3. Finally, the earmold assembly 4 amplifies the processed sound signals, effectively achieving clear sound reproduction and ensuring that the output sound accurately matches the hearing needs of the hearing-impaired patient, thereby improving the hearing clarity and comfort of the patient. Furthermore, when the ventilation tube 5 is installed inside the ventilation hole 40, the blocking member 6 can tightly seal the gap space 7 formed between the inner wall of the ventilation hole 40 and the outer wall of the ventilation tube 5, effectively preventing air from escaping from the gap space 7, thus ensuring stable ventilation of the ventilation tube 5 and guaranteeing the accuracy of the ear canal ventilation channel diameter adjustment.

[0019] In this solution, a ventilation hole 40 is opened inside the earmold assembly 4, and a ventilation tube 5 with a blocking component 6 is detachably installed inside the ventilation hole 40, forming a flexibly adjustable ventilation structure that can effectively alleviate the ear occlusion effect. When hearing-impaired patients need to switch to different hearing aids due to changes in usage scenarios, it is not necessary to frequently change hearing aids with ventilation holes of different diameters. The diameter of the ear canal ventilation channel can be flexibly changed simply by installing or removing the ventilation tube: when hearing-impaired patients need a larger ear canal ventilation channel diameter, the ventilation tube 5 can be removed or not installed, and the diameter of the ventilation hole 40 can be used directly as the ear canal ventilation channel diameter, which is suitable for mild to moderate hearing-impaired patients who need some low-frequency compensation; when hearing-impaired patients need a smaller ear canal ventilation channel diameter, the ventilation tube 5 can be installed, and the diameter of the ventilation tube 5 can be used as the ear canal ventilation channel diameter, which is suitable for hearing-impaired patients with high-frequency hearing loss but normal or near-normal low-frequency hearing. This design effectively avoids the hassle of frequently changing hearing aids and improves the convenience of daily use for hearing-impaired patients.

[0020] Preferably, the blocking element 6 is a cotton sleeve, a rubber sleeve, or a silicone sleeve. In this embodiment, the blocking element 6 is a cotton sleeve. Because the cotton sleeve is made of a soft material, during the installation or removal of the vent tube 5, it not only effectively prevents air from escaping from the gap space 7 between the inner wall of the vent hole 40 and the outer wall of the vent tube 5, but also reduces unnecessary wear on the inner wall of the vent hole 40. In other embodiments, the blocking element 6 can be a rubber sleeve or a silicone sleeve. The rubber sleeve has better elasticity and sealing properties, adapting to sealing requirements of different gap sizes and ensuring a long-lasting sealing effect; the silicone sleeve has excellent biocompatibility and aging resistance, making it safer and more stable when in long-term contact with the ear canal environment.

[0021] Preferably, the diameter of the vent 40 is... The diameter of the vent pipe 5 is 2.0mm~2.5mm. The thickness is 0.5mm to 1.0mm. In this embodiment, for example... Figure 2-3 As shown, the diameter of the vent 40 The diameter of the vent pipe 5 is 2.0 mm. The vent 40, with a diameter of 1.0mm, provides extremely strong low-frequency attenuation, effectively eliminating the occlusion effect and is suitable for hearing-impaired patients with high-frequency hearing loss but normal or near-normal low-frequency hearing; the vent 5, with a diameter of 1.0mm, provides moderate low-frequency attenuation, which can alleviate the occlusion effect to some extent and is suitable for mild to moderate hearing-impaired patients who require some low-frequency compensation.

[0022] Preferably, the earmold assembly 4 includes an eardrum body 41 and an ear cap 42, the ear cap 42 having an opening 420; the ear cap 42 is fitted onto one end of the eardrum body 41, and a vent 40 is located inside the eardrum body 41, the vent 40 communicating with the opening 420 on the ear cap 42. In this embodiment, as... Figure 1-2 As shown, when a hearing-impaired patient wears the hearing aid, the ear cap 42 is in close contact with the ear canal, and the air in the ear canal can smoothly enter the vent 40 through the opening 420 on the ear cap 42, and then be discharged to the outside of the hearing aid through the vent 40, thereby alleviating the occlusion effect.

[0023] Preferably, the earmold assembly 4 further includes a heart rate sensor 43. A mounting groove 411 is formed on the outer side of the eardrum body 41, and the heart rate sensor 43 is mounted in the mounting groove 411. The heart rate sensor 43 is communicatively connected to the controller. In this embodiment, as... Figure 2-3 As shown, when a hearing-impaired patient wears the hearing aid, the earmold assembly 4 fits snugly against the ear, allowing the heart rate sensor 43 to come into close contact with the ear skin, collecting the patient's heart rate signal. The controller then performs real-time analysis and processing of the heart rate signal data. This design enables the hearing aid to perform its core hearing assistance function while also providing additional health monitoring capabilities.

[0024] Preferably, the outer surface of the eardrum body 41 is provided with a plurality of positioning protrusions 412, and the plurality of positioning protrusions 412 are evenly distributed along the periphery of the eardrum body 41. In this embodiment, as shown... Figure 1 As shown, when a hearing-impaired patient needs to remove their hearing aid, the positioning protrusions 412 evenly distributed on the outer side of the eardrum body 41 can increase the contact friction between the human hand and the outer side of the eardrum body 41, allowing the hearing-impaired patient to easily and stably remove the ear mold assembly 4 from the ear canal, thereby improving the convenience of use.

[0025] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
