Description

Technical Field

[0001] This utility model relates to the field of hearing aid technology, specifically to a hearing aid that is easy to wear. Background Technology

[0002] As a hearing aid, hearing aid technology has evolved from analog signal processing to digital noise reduction algorithms, and its structural design has gradually moved towards miniaturization and intelligence. Currently, hearing aids mainly utilize the following technological approaches:

[0003] Behind-the-ear hearing aids: These are externally mounted hearing aids that rely on ear hooks to be fixed behind the ear. They are bulky and have an unstable center of gravity, and prolonged wear can easily cause pressure pain on the ear.

[0004] In-the-ear hearing aids: These use a customized shell to fit the ear canal, but traditional injection molding processes cannot accurately adapt to the curvature of all users' ear canals, resulting in excessive local pressure or insufficient seal when worn, which can easily cause ear canal inflammation.

[0005] Charging technology: Current mainstream solutions include exposed charging pin contact charging (which is prone to oxidation and poor contact) and wireless charging modules (which require built-in coils and occupy housing space), both of which present a contradiction between structural complexity and wearing comfort.

[0006] Acoustic component assembly: The sound-generating unit is usually fixed to the shell by adhesive or welding. The process requires high precision, and the rigid connection is prone to transmitting vibration noise, which can cause howling interference.

[0007] Although existing technologies have solved some acoustic performance problems, there are still significant shortcomings in terms of ease of use. For example, most hearing aid wearers are currently elderly people. Wearing a hearing aid requires first aligning it with the outer side of the ear and then rotating it to complete the wearing action. Furthermore, due to hand tremors, elderly people often cannot accurately align the hearing aid when wearing it, which affects the wearing efficiency. Therefore, it is necessary to manufacture a hearing aid that is easy for the elderly to wear to solve this problem. Utility Model Content

[0008] The main purpose of this invention is to provide a hearing aid that is easy to wear, in order to solve the technical problem that hearing aids are inconvenient to wear in the prior art.

[0009] To achieve the above objectives, the present invention proposes a convenient hearing aid, comprising a receiving component for capturing sound and a playback component for outputting sound; the receiving component and the playback component are connected by a flexible bending member, the bending member being used to adjust the relative connection angle between the receiving component and the playback component.

[0010] Preferably, the receiving component includes a microphone housing, the playback component includes a broadcast housing, and the bending component includes a first connecting rod and a second connecting rod.

[0011] One end of the first connecting rod is connected to one end of the receiver housing, and one end of the second connecting rod is connected to one end of the broadcast housing. The end of the second connecting rod away from the broadcast housing is rotatably connected to the end of the first connecting rod away from the receiver housing.

[0012] Preferably, the second connecting rod has a first groove recessed at one end near the first connecting rod, and the first limiting component includes a first limiting block slidably disposed in the first groove. The end of the first limiting block near the bottom of the first groove is connected by a first elastic member. The first elastic member is used to push the end of the first limiting block away from the first groove out of the first groove. The end of the first connecting rod near the second connecting rod has a second groove recessed for the first limiting block to be inserted.

[0013] The bending component also includes a release component for pushing the first limiting block toward the end opposite to the second groove, so that the first limiting block disengages from the second groove.

[0014] Preferably, the outer wall of the first connecting rod is recessed to form a third groove that communicates with the second groove, and the recess direction of the third groove is perpendicular to the recess direction of the second groove.

[0015] The release limiting component includes a rod slidably disposed in the third groove, with one end of the rod located in the third groove and the other end located in the third groove. The end of the rod located in the third groove can extend into the second groove. The end of the rod located in the third groove is provided with a second elastic element for abutting against the side wall of the second groove. The release limiting component also includes a second limiting component for fixing the position of the rod after the end of the rod located in the third groove extends into the second groove.

[0016] Preferably, the inner wall of the third groove is formed with a fourth groove, and the extending direction of the fourth groove is perpendicular to the extending direction of the third groove.

[0017] The second limiting component includes a second limiting block slidably disposed in the fourth groove. One end of the second limiting block near the bottom of the fourth groove is connected to the fourth groove via a third elastic member. The third elastic member is used to push the second limiting block out of the fourth groove. The outer wall of the insertion rod is recessed to form a fifth groove for the second limiting block to be inserted. The second limiting component also includes a disengaging member for driving the second limiting block out of the fifth groove.

[0018] Preferably, the release element includes a cable, one end of which is connected to the end of the second limiting block near the fourth groove, and the other end is connected to the second connecting rod; a through hole for the cable to move is also formed on the first connecting rod.

[0019] Preferably, the outer wall of the first limiting block near the first groove is provided with a slider, the groove wall of the first groove is recessed to form a sliding groove for the slider to slide, the sliding groove is provided with a first vibrating plate near the groove wall of the first groove, and the slider is provided with a second vibrating plate that can contact the first vibrating plate.

[0020] Preferably, the playback component further includes an earplug for insertion into the ear canal, the earplug being located on the side of the playback housing opposite to the second link, and the earplug having a built-in detection module for detecting whether the earplug has entered the ear canal.

[0022] Preferably, an isolation layer is provided on the outer side of the bending component.

[0023] In this invention, the design systematically solves the core pain points of existing hearing aids in terms of wearing efficiency, fit, comfort, and stability through an adjustable bending component. Compared to the common hearing aids that require alignment with the outer ear before screwing in, this hearing aid only requires placing it on the inner side of the upper ear and then closing the buckle to complete the wearing process. This solves the problem of elderly people misaligning their hearing aids due to hand tremors. It provides an innovative path for the humanized design of hearing aids, especially addressing the operational difficulties and physiological needs of elderly users. It greatly improves the wearing efficiency of hearing aids for the elderly, and its technological extensibility (such as combining bone conduction and intelligent noise reduction) can further expand its application scenarios.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0039] This utility model proposes a hearing aid that is easy to wear.

[0040] Please refer to Figures 1 to 6 The wearable hearing aid includes a receiving component 1 for capturing sound and a playback component 2 for outputting sound; the receiving component 1 and the playback component 2 are connected by a flexible bending member 3, which is used to adjust the relative connection angle between the receiving component 1 and the playback component 2.

[0041] In the technical solution of this utility model, the design systematically solves the core pain points of existing hearing aids in terms of wearing efficiency, fit, comfort, and stability through the adjustable bending component 3. Compared with the common hearing aids that require first aligning with the outer side of the ear and then screwing it in, this utility model hearing aid only requires placing the hearing aid on the inner side of the upper ear and then closing the buckle to complete the wearing process. This solves the problem of elderly people not being able to align with the ear due to hand tremors. In particular, it provides an innovative path for the humanized design of hearing aids, especially for the operational difficulties and physiological needs of elderly users. It greatly improves the wearing efficiency of hearing aids for the elderly, and its technical extensibility (such as combining bone conduction and intelligent noise reduction) can further expand the application scenarios.

[0042] Please refer to the appendix. Figure 1-3The receiving component 1 includes a receiver housing 11, and the playback component 2 includes a broadcast housing 21; the bending component 3 includes a first connecting rod 31 and a second connecting rod 32.

[0043] One end of the first connecting rod 31 is connected to one end of the receiver housing 11, and one end of the second connecting rod 32 is connected to one end of the broadcast housing 21. The end of the second connecting rod 32 away from the broadcast housing 21 is rotatably connected to the end of the first connecting rod 31 away from the receiver housing 11. A first limiting component 33 is provided between the first connecting rod 31 and the second connecting rod 32 to restrict the mutual rotation of the first connecting rod 31 and the second connecting rod 32. The ear hook, which is an arc shape, is formed by the cooperation between the receiver shell 11, the broadcast shell 21, the first connecting rod 31, and the second connecting rod 32 to hang on the ear. Furthermore, the rotational connection between the first connecting rod 31 and the second connecting rod 32 changes the angle between the receiver shell 11 and the broadcast shell 21, thereby further altering the angle of the arc shape formed by the above cooperation. Increasing the arc angle of the ear hook makes it easier and faster to wear the hearing aid. The first limiting component 33 can limit the arc angle of the ear hook, preventing changes in the arc angle during wear to ensure the stability of the hearing aid and further prevent it from falling off. Simultaneously, the first limiting component 33 can also expand the fitting range of the hearing aid by changing the arc of the ear hook to increase the fit to the auricle. This invention only changes the wearing structure of the hearing aid, allowing it to bend; its hearing aid function is no different from hearing aids on the market.

[0044] Please refer to the appendix. Figure 3 The second connecting rod 32 has a first groove 32a recessed at one end near the first connecting rod 31. The first limiting component 33 includes a first limiting block 331 slidably disposed in the first groove 32a. The end of the first limiting block 331 near the bottom of the first groove 32a is connected by a first elastic member 332. The first elastic member 332 is used to push the end of the first limiting block 331 away from the first groove 32a out of the first groove 32a. The end of the first connecting rod 31 near the second connecting rod 32 has a second groove 31a for the first limiting block 331 to be inserted.

[0045] The bending component 3 also includes a release component 34 for pushing the first limiting block 331 toward the end opposite to the second groove 31a, so that the first limiting block 331 disengages from the second groove 31a. When the first connecting rod 31 and the second connecting rod 32 rotate, and the first limiting block 331 passes through the second groove 31a, the first elastic component releases elastic potential energy. Under the action of the first elastic component, the first limiting block 331 can move toward the side opposite to the first groove 32a, and finally insert the first limiting block 331 into the second groove 31a. At this time, the first connecting rod 31 and the second connecting rod 32 cannot rotate, thereby fixing the angle between the receiving component 1 and the playback component 2. The release component 34 can adjust the relative connection angle between the receiving component 1 and the playback component 2 after the first limiting block 331 is disengaged from the second groove 31a.

[0046] Please refer to the appendix. Figure 3 and 5 The outer wall of the first connecting rod 31 is recessed to form a third groove 31b that communicates with the second groove 31a. The recess direction of the third groove 31b is perpendicular to the recess direction of the second groove 31a.

[0047] The release limiting component 34 includes a rod 341 slidably disposed in the third groove 31b. One end of the rod 341 is located in the third groove 31b, and the other end is located in the third groove 31b. The end of the rod 341 located in the third groove 31b can extend into the second groove 31a. The end of the rod 341 located in the third groove 31b is provided with a second elastic element 342 for abutting against the side wall of the second groove 31a. The release limiting component 34 also includes a second limiting component 343 for fixing the position of the rod 341 after the end of the rod 341 located in the third groove 31b extends into the second groove 31a. Pressing down one end of the insertion rod 341 outside the third groove 31b causes the insertion rod 341 to move closer to the end of the second groove 31a and enter the second groove 31a. During the process of the insertion rod 341 entering the second groove 31a, the insertion rod 341 will abut against the first limiting block 331, and at the same time push the first limiting block 331 away from the second groove 31a, so that the first limiting block 331 will disengage from the second groove 31a, and further enable the angle between the receiving component 1 and the playback component 2 to be adjusted. The second limiting component 343 can fix the position of the insertion rod 341 pushing the first limiting block 331 away from the second groove 31a, so as to prevent the first limiting block 331 from returning to the second groove 31a before the angle between the first link 31 and the second link 32 has changed, so as to ensure that the angle between the first link 31 and the second link 32 can be changed smoothly.

[0048] Please refer to the appendix. Figure 5The inner wall of the third groove 31b is formed with a fourth groove 31c, and the extension direction of the fourth groove 31c is perpendicular to the extension direction of the third groove 31b.

[0049] The second limiting component 343 includes a second limiting block 3431 slidably disposed in the fourth groove 31c. One end of the second limiting block 3431 near the bottom of the fourth groove 31c is connected to the fourth groove 31c via a third elastic member 3432. The third elastic member 3432 is used to push the second limiting block 3431 out of the fourth groove 31c. The outer wall of the insertion rod 341 is recessed to form a fifth groove 341a for the second limiting block 3431 to be inserted. The second limiting component 343 also includes a disengaging member for driving the second limiting block 3431 out of the fifth groove 341a. While the insertion rod 341 is in the position of pushing the first limiting block 331 out of the second groove 31a, the second limiting block 3431 is pushed into the fifth groove 341a by the third elastic member 3432. At this time, the push rod cannot slide in the third groove 31b when the hand is released, so as to prevent the first limiting block 331 from entering the second groove 31a. When the first connecting rod 31 and the second connecting rod 32 rotate relative to each other and the angle changes, the release member will drive the second limiting block 3431 to move towards the side away from the fifth groove 341a. After the second limiting block 3431 is released from the fifth groove 341a, the push rod will move towards the side away from the second groove 31a under the action of the second elastic member, so that the insertion rod 341 exits the second groove 31a. At this time, when the second connecting rod 32 rotates and the first limiting block 331 passes through the second groove 31a, the first limiting block 331 will re-enter the second groove 31a, completing the closed loop of the whole action.

[0050] The relative angle between the receiving component 1 and the playback component 2 is adjusted by the inter-linkage between the various parts of the bending component 3.

[0051] Please refer to the appendix. Figure 6 The release mechanism includes a cable 3433, one end of which is connected to the end of the second limiting block 3431 near the fourth groove 31c, and the other end is connected to the second connecting rod 32. The first connecting rod 31 also has a through hole 31d for the cable 3433 to move. When the angle between the second connecting rod 32 and the first connecting rod 31 changes, the cable 3433 will be pulled along with the rotation of the second connecting rod 32. Simultaneously, the cable 3433 will cause the second limiting block 3431 to disengage from the fifth groove 341a, thus achieving a linkage action where the push rod leaves the second groove 31a after the first limiting block 331 is no longer within the insertion range of the second groove 31a, so that the first limiting block 331 can re-enter the second groove 31a next time.

[0052] As the first limiting block 331 re-enters the second groove 31a, the cable 3433 wrapped around the second connecting rod 32 is released simultaneously to ensure the next pulling action of the cable 3433. At the same time, due to the release of the cable 3433, the elastic potential energy of the third elastic release drives the second limiting block 3431 to move away from the fourth groove 31c, so that the second limiting block 3431 re-enters the fifth groove 341a next time, ensuring the integrity of the entire action.

[0053] Please refer to the appendix. Figure 4 The first limiting block 331 has a slider 38 on its outer wall near one end of the first groove 32a. A groove 32b is recessed in the groove wall of the first groove 32a to allow the slider 38 to slide. A first vibrating plate 35 is provided on the groove wall near the first groove 32a. The slider 38 has a second vibrating plate 36 that can contact the first vibrating plate 35. When the first limiting block 331 enters the second groove 31a, the first elastic element 332 possesses elastic potential energy, causing the first vibrating plate 35 and the second vibrating plate 36 to strike each other. Simultaneously, the first vibrating plate 35 and the second vibrating plate 36 vibrate and produce sound, thus prompting the user to complete the fixing action of the receiving component 1 and the playback component 2.

[0054] Please refer to the appendix. Figure 1 The playback component 2 also includes an earplug 22 for insertion into the ear canal. The earplug 22 is located on the side of the playback shell 21 opposite to the second connecting rod 32. The earplug 22 has a built-in detection module for detecting whether the earplug 22 has entered the ear canal. By using the built-in detection module in the earplug 22, the hearing aid is upgraded from a "passive fitting" to an "active sensing" intelligent device, solving the problem of wearing deviation caused by the decline in hand dexterity in the elderly, while taking into account the needs of acoustic performance optimization, ear canal health protection, and intelligent fitting. Its technological extensibility (such as combining AI algorithms to predict wearing status) can further expand application scenarios and provide an innovative paradigm for age-appropriate design of hearing aids.

[0055] Please refer to the appendix. Figure 1 The detection module is one of the following: a pressure sensor, an optical detection module, an infrared detection module, a human body capacitance detection module, and an ear canal air pressure monitoring module. The detection module is connected to an app compatible with the hearing aid. It alerts the user via vibration or the app to ensure proper fit, allowing children or the wearer to monitor the hearing aid's effectiveness and thus guarantee its comfort.

[0056] Please refer to the appendix. Figure 1 An isolation layer 37 is provided on the outer side of the bending component 3. The isolation layer 37 can prevent injury to the human body when the first link 31 and the second link 32 rotate, and at the same time prevent impurities from entering the inside of the bending component 3, thereby improving the service life of the bending component 3.

[0057] The specific operation method of this utility model is as follows: Manually press down the end of the insertion rod 341 located outside the third groove 31b, so that the insertion rod 341 moves closer to the end near the second groove 31a and enters the second groove 31a. During the process of the insertion rod 341 entering the second groove 31a, the insertion rod 341 will abut against the first limiting block 331, and at the same time push the first limiting block 331 away from the second groove 31a, finally causing the first limiting block 331 to disengage from the second groove 31a. When the insertion rod 341 is in the position of pushing the first limiting block 331 out of the second groove 31a... At position 1a, the second limiting block 3431, driven by the third elastic element 3432, is inserted into the fifth groove 341a. When the push rod is released, it cannot slide in the third groove 31b. At this time, the angle between the second connecting rod 32 and the first connecting rod 31 is manually changed to increase the angle between the playback component 2 and the receiving component 1. The next step is to place the hearing aid with the increased angle on the inner side of the upper ear, and then close the playback component 2 and the receiving component 1 to restore the playback component 2 and the receiving component 1 to the initial angle, thus completing the hearing aid wearing action.

[0058] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
