Description

Technical Field

[0001] This utility model relates to the field of headphones and hearing aids, and in particular to a hearing aid headphone and hearing aid that can improve user comfort. Background Technology

[0002] Hearing aids, as sophisticated electroacoustic assistive devices, are essentially miniaturized and intelligent sound amplification equipment. Their core function lies in using multi-level signal processing technology to accurately capture and scientifically amplify sound signals from the external environment that are originally below the hearing threshold of the hearing-impaired individual. Specifically, the hearing aid first uses a high-sensitivity microphone to collect sound waves, converting them into electrical signals. These signals are then intelligently analyzed and processed by the mainboard, allowing for personalized gain adjustment based on the degree of hearing loss at different frequencies. The processed electrical signals are converted into acoustic signals by a speaker and precisely delivered to the hearing-impaired individual's ear canal through the sound outlet. When the acoustic signal vibrates and stimulates the hair cells in the cochlea, nerve impulses are transmitted through the auditory nerve to the auditory center of the cerebral cortex. After integration and processing by the central nervous system, a complete auditory perception is formed.

[0003] This technology, based on the principle of "sound-to-electro-acoustic" conversion, provides a scientific and effective hearing compensation solution for people with varying degrees of hearing impairment. It can significantly improve the social participation and quality of life of people with hearing impairment, and has irreplaceable clinical value and social significance in the field of rehabilitation medicine.

[0014] The beneficial effects of the above-mentioned technical solutions provided in the embodiments of this utility model include at least the following: This invention provides a hearing aid earphone that improves user comfort. The speaker is housed in a first receiving cavity, and the microphone assembly is housed in a second shell, effectively separating the microphone assembly and speaker. This physically blocks the path of sound reflection from the speaker through the ear canal into the microphone assembly, preventing feedback and thus achieving an anti-feedback effect. This improves the stability and clarity of audio transmission, providing users with a clearer and more comfortable listening experience. Furthermore, because this design effectively avoids feedback, the sound outlet does not need to be inserted deeply into the ear canal, avoiding excessive pressure and irritation on the deep part of the ear canal. This significantly reduces the feeling of a foreign object, achieving a virtually imperceptible wearing experience and alleviating potential ear discomfort or pain from prolonged wear, thereby enhancing user comfort.

[0018] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0019] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," "far," "near," "front," and "rear," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 mechanical connection or an electrical 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.

[0021] The inventors discovered that in existing hearing aids, the microphone and speaker are integrated into a single housing. The two are too close together and lack effective isolation. Because of this proximity, the sound emitted by the speaker is easily picked up by the microphone again, resulting in feedback, which severely interferes with the user's auditory experience and reduces the performance and reliability of the hearing aid. To avoid this feedback and ensure sound transmission, the sound outlet is usually inserted deeply into the ear canal. This makes wearing the hearing aid uncomfortable, causing a noticeable foreign body sensation, and prolonged wear may even lead to ear discomfort or pain, significantly impacting user acceptance and willingness to use the hearing aid.

[0022] To address the aforementioned issues, the inventors developed a hearing aid headphone that improves user comfort. This headphone effectively avoids feedback and reduces the depth of the sound outlet insertion into the ear canal, achieving a seamless wearing experience and enhancing stability and comfort during use.

[0023] Example 1 See Figure 1 and Figure 2 This embodiment proposes a hearing aid headphone that improves user comfort, comprising: a first housing 1, a second housing 2, a flexible connector 3, a speaker 4, and a microphone assembly 5. The first housing 1 and the second housing 2 are connected by the flexible connector 3. The first housing 1 includes a speaker shell 101 and a sound outlet 102. The speaker shell 101 is connected to the flexible connector 3, and the sound outlet 102 can be inserted into the ear canal. The speaker shell 101 and the sound outlet 102 are detachably connected and enclose a first receiving cavity (not shown in the figure), in which the speaker 4 is disposed. The microphone assembly 5 is disposed in the second housing 2. The flexible connector 3 can abut against the helix of the ear, and the second housing 2 can fit against the back of the ear. The flexible connector 3 and the second housing 2 can be used to hold the sound outlet 102 in the ear canal.

[0024] In use, the flexible connector 3 abuts against the helix of the ear, and the second housing 2 abuts against the back of the ear, thus keeping the sound outlet 102 inside the ear canal. Because the microphone assembly 5 and the speaker 4 are separated, the path of sound reflection from the speaker 4 through the ear canal directly entering the microphone assembly 5 and causing feedback is physically blocked, thus achieving an anti-feedback effect. This improves the stability and clarity of audio transmission, providing users with a clearer and more comfortable listening experience. Simultaneously, because this design effectively avoids feedback, the sound outlet 102 does not need to be inserted very deep into the ear canal, avoiding excessive pressure and stimulation on the deep part of the ear canal, significantly reducing the feeling of a foreign object, achieving a seamless wearing experience, and alleviating ear discomfort or pain that may be caused by prolonged wear, thus improving the comfort of use. By using the flexible connector 3 abutting against the helix of the ear and the second housing 2 abutting against the back of the ear, the sound outlet 102 is cleverly fixed inside the ear canal, ensuring the stability of the entire hearing aid headset, preventing it from easily falling off, and facilitating daily activities for the user.

[0025] In one specific embodiment, see [reference] Figure 1 The second housing 2 includes a first outer shell 201 and a second outer shell 202, which are detachably connected and enclose a second receiving cavity (not shown in the figure). Because the first outer shell 201 and the second outer shell 202 are detachably connected, it greatly facilitates the maintenance and upgrading of the electronic components inside the hearing aid's earpiece, reducing repair costs and time. The detachable connection can be achieved using existing technologies such as magnetic attraction, snap-fit, or threaded connection.

[0026] See Figure 1 The first outer shell 201 is connected to the flexible connector 3. The first outer shell 201 is oriented towards the back of the ear and can fit snugly against the back of the ear. This not only reduces discomfort during wearing and improves wearing comfort, but this snug fit design, combined with the flexible connector 3, can also effectively improve the wearing stability of the hearing aid headphones.

[0027] See Figure 1 and Figure 2 The microphone assembly 5 includes a microphone body 501 and a receiver 502 connected to each other. The microphone body 501 is located in the second receiving cavity, and the receiver 502 is located on the outer side of the first housing 201. This allows the receiver 502 to capture external sounds more widely and directly, ensuring the sensitivity and accuracy of sound reception. The sound is accurately transmitted to the microphone body 501, which then converts the sound signal into an electrical signal for further processing, providing users with a clearer and more realistic sound experience.

[0028] In one specific embodiment, see [reference] Figure 2 The hearing aid headset of this embodiment also includes a mainboard 6 and a battery 7 disposed in the second receiving cavity. The mainboard 6, as the core control component of the hearing aid headset, establishes an electrical connection with the speaker 4 and the microphone body 501. The microphone body 501 is responsible for converting received external sound signals into electrical signals and transmitting them to the mainboard 6. The mainboard 6 processes these electrical signals and then transmits the processed signals to the speaker 4. The speaker 4 converts the electrical signals back into acoustic signals and transmits them to the user's ear canal through the sound outlet 102, realizing the basic functions of the hearing aid headset, with a high degree of functional integration. The battery 7 is electrically connected to the mainboard 6 and provides power support for the operation of the entire hearing aid headset. Specifically, the battery 7 supplies power to the mainboard 6, and the mainboard 6 then distributes the electrical energy to the speaker 4, microphone body 501, and other electronic components connected to it, ensuring that each component can function normally.

[0029] The second cavity has a larger space than the first cavity. Based on this feature, the motherboard 6 and battery 7 are located in the second cavity. Other electronic components (such as the hearing aid microphone FPC10, antenna FPC11, etc.) can also be located in the second cavity. The larger space allows for a more rational arrangement of the distribution of electronic components, avoiding mutual interference between components due to limited space, thus optimizing the internal structure and performance. It also facilitates heat dissipation and ensures the stability of the hearing aid during long-term use.

[0030] In one specific embodiment, see [reference] Figure 1 and Figure 2The hearing aid headset of this embodiment also includes a charging port 8 located on the outer side of the second housing 202. The charging port 8 is connected to the battery 7 via a wire (not shown in the figure) to form a complete charging circuit. The charging port 8 can be electrically connected to an external power source (such as a charging case, wireless charger, or wired charger). In use, the charging port 8 is physically connected to the corresponding interface of the external power source to charge the battery 7, which is then used to power the various electronic components of the hearing aid headset. Users do not need to disassemble any parts of the hearing aid headset; they only need to directly connect the charging port 8 to the external power source to start charging. The operation is simple and convenient, greatly improving the convenience and efficiency of charging, and is especially suitable for elderly users or people with mobility impairments.

[0031] In one specific embodiment, see [reference] Figure 1 The outer surface of the first shell 201 is provided with a contoured surface that conforms to the contour of the back of the ear, which is designed based on ergonomic principles. When the user wears the hearing aid, this contoured surface can precisely match the unique contour of the back of the ear. During wear, the back of the ear will exert a certain amount of pressure on the first shell 201, and the presence of the contoured surface allows this pressure to be evenly distributed across the entire contact surface, avoiding the pressure and pain caused by excessive local pressure on the skin behind the ear, greatly improving the comfort of the user when wearing the hearing aid for extended periods.

[0032] In one specific embodiment, see [reference] Figure 2 The first receiving cavity houses an in-ear detection FPC12, which integrates specific sensors, such as capacitive or optical sensors. Taking a capacitive sensor as an example, it detects the wearing status by utilizing the capacitance change between the human body and the sensor. When the hearing aid is not inserted into the ear canal, the capacitance value between the capacitive sensor and the surrounding environment is within a reference range. However, when the hearing aid is correctly inserted into the ear canal, i.e., in a wearing state, the human tissue approaches the capacitive sensor, changing the capacitance value. The circuitry within the in-ear detection FPC12 monitors this capacitance change in real time and converts it into an electrical signal. After receiving these electrical signals, the in-ear detection FPC12 determines the current wearing status. If the hearing aid is being worn, the in-ear detection FPC12 sends a start signal to the main board 6. Upon receiving the start signal, the main board 6 controls the electronic components of the hearing aid to start working. Conversely, when it detects that the hearing aid has been removed from the ear canal, i.e., the hearing aid is not inserted into the ear canal, the in-ear detection FPC12 sends a stop signal, and the main board 6 puts the electronic components into a sleep or shutdown state to save power.

[0033] Users do not need to manually operate the hearing aid headphones to start or stop them; they only need to put the hearing aid headphones in the ear canal normally or remove them to complete the corresponding operation automatically. This automated start-stop method greatly improves the convenience of use, especially for elderly users or users with poor hand dexterity, avoiding cumbersome manual operation steps and making the use of hearing aids easier and more comfortable.

[0034] In one specific embodiment, see [reference] Figure 1 and Figure 2 The flexible connector 3 includes an elastic sheath 301 and a memory steel wire 302 encased within the elastic sheath 301. Based on the contours of the human ear, the elastic sheath 301 is designed in a C-shape. When the user wears the hearing aid, this C-shape naturally wraps around specific areas of the ear, such as the helix, conforming to the ear's curve and providing a basic framework for stable hearing aid wear. The memory steel wire 302 has unique elastic properties. During wear, the memory steel wire 302 undergoes elastic deformation, generating an elastic clamping force. This elastic clamping force allows the entire flexible connector 3 to fit tightly against the ear, stably fixing the first outer shell 201 and the speaker shell 101 in their respective positions, ensuring that the sound outlet 102 is accurately inserted into the ear canal and remains stable. Furthermore, the memory steel wire 302 has shape memory function; even after repeated bending and wearing, it can return to its initial shape, continuously providing a stable elastic clamping force.

[0035] The combination of the elastic clamping force provided by the memory steel wire 302 and the fit of the elastic sheath 301 into the C-shaped structure with the ear ensures that the hearing aid earphone can be firmly fixed in the ear during wear, and is not easy to fall off due to the user's daily activities, such as head turning, walking, and exercise, thus ensuring wearing stability. At the same time, both the memory steel wire 302 and the elastic sheath 301 are elastic, and can be appropriately adjusted and adapted to different users' ear shapes and sizes, providing good flexibility.

[0036] In one specific embodiment, see [reference] Figure 1 and Figure 2 The hearing aid earphone in this embodiment also includes an ear cover 9 fitted onto the sound outlet 102. The ear cover 9 has an asymmetrical funnel-shaped structure, having, for example, Figure 1 The ear tips are shown to have a gradually narrowing shape. This asymmetrical funnel-shaped structure better conforms to the inner wall of the ear canal, and its gradually narrowing shape guides acoustic signals more accurately into the depths of the ear canal, improving transmission efficiency and quality. The ear tips 9 can adapt to different ear canal sizes and can be equipped with multiple spare ear tips of different sizes for users to choose from, achieving personalized fit.

[0037] Because the ear tip 9 can adapt to the size of the ear canal and its asymmetrical funnel-shaped structure fits the ear canal well, it reduces the pressure and friction of the ear tip 9 on the skin around the ear canal, avoiding discomfort caused by wearing it for a long time. This allows users to wear hearing aids more comfortably for a long time and improves wearing comfort.

[0038] In one specific embodiment, see [reference] Figure 1 and Figure 2 The speaker housing 101 and the sound outlet 102 are detachably connected via a snap-fit ​​assembly. The snap-fit ​​assembly includes a resilient claw (not shown in the figure) on the speaker housing 101 and an annular groove (not shown in the figure) on the sound outlet 102. During the engagement of the speaker housing 101 and the sound outlet 102, the resilient claw gradually approaches the annular groove until it engages, thus connecting the speaker housing 101 and the sound outlet 102 and ensuring a secure and stable connection. When it is necessary to disassemble the speaker housing 101 and the sound outlet 102, no additional tools are required; the user simply applies force to separate the resilient claw from the annular groove. The snap-fit ​​assembly design enables quick disassembly and installation of the speaker housing 101 and the sound outlet 102, greatly improving the convenience and efficiency of operation.

[0039] In one specific embodiment, see [reference] Figure 1 and Figure 2 The second housing 2 also includes a first magnet (not shown in the figure) and a second magnet (not shown in the figure) with opposite magnetic poles. The first magnet is connected to the inner wall of the first housing 201, and the second magnet is connected to the inner wall of the second housing 202. The design of the first and second magnets makes the installation and disassembly of the first and second housings 201 and 202 more convenient. During installation, the user only needs to snap the first and second housings 201 together; the mutual attraction between the first and second magnets securely connects them. During disassembly, the user only needs to apply appropriate external force to overcome the attraction between the first and second magnets to separate the first and second housings 201 and 202. This facilitates the inspection or cleaning of electronic components within the second housing cavity. Similarly, after inspection or cleaning, the first and second housings 201 and 202 can be quickly reassembled, improving maintenance and replacement efficiency and reducing user costs and time.

[0040] In one specific embodiment, the hearing aid headset has a programmable audio channel, meaning the audio processing path (channel) inside the hearing aid headset is software-programmable and can dynamically switch between different processing modes or "channels" based on the environment or user selection. It can automatically or manually switch between different processing modes (e.g., quiet environment, noisy restaurant, music listening, telephone mode). The gain, compression, and other parameters of each channel (frequency range) can be finely adjusted according to the user's hearing loss and personal preferences to achieve highly customized sound compensation.

[0041] In one specific embodiment, the hearing aid headset is equipped with a prompt unit, which is a unit specifically used to emit prompt sounds and voice information. It can directly inform the user of information such as the current processing mode, volume, and power consumption through voice, which greatly improves the user's perception of the device status and the convenience of operation.

[0042] In existing hearing aid headphones, there are generally two headphones: a right earpiece and a left earpiece. Since the degree of hearing loss in a user's left and right ears differs, the hearing compensation parameters configured in the right and left earpieces are different. Therefore, users need to identify the markings (such as colors or letters) on the right and left earpieces to wear them correctly. If the left and right earpieces are worn backwards, the desired hearing aid effect will not be achieved, which is inconvenient for visually impaired users or the elderly.

[0043] To address the aforementioned issues, in this embodiment, refer to... Figure 2 A triaxial sensor (not shown in the figure) is installed in the second receiving cavity, and this triaxial sensor is connected to the mainboard 6. The mainboard 6 pre-stores the first hearing loss compensation parameters corresponding to the left ear and the second hearing loss compensation parameters corresponding to the right ear. The triaxial sensor is used to detect the three-dimensional posture data of the entire hearing aid headset when it is worn, and transmits the three-dimensional posture data to the mainboard 6.

[0044] Upon initial use, the hearing aid headphones need to be set up. Place either headphone in the left ear, and the three-axis sensor continuously monitors the headphone's three-dimensional posture data within the ear canal. This data is then transmitted to the mainboard 6, which records it as the left ear reference model. The same headphone (or another headphone) is placed in the right ear, and the process is repeated, with the mainboard 6 recording the right ear reference model. The mainboard 6 then binds the left ear reference model to a preset first hearing loss compensation parameter and the right ear reference model to a second hearing loss compensation parameter. During daily use, the three-axis sensor continuously monitors the three-dimensional posture data and transmits it to the mainboard 6. The mainboard 6 compares this data with the left and right ear reference models, calculates the matching degree using algorithms (such as Euclidean distance and cosine similarity), determines the current wearing position (left or right ear), and automatically calls the corresponding hearing loss compensation parameters based on the matching result, driving the speaker 4 to output the appropriate acoustic signal.

[0045] Users do not need to distinguish between headphones by labels, making it especially convenient for visually impaired or elderly people to operate and reducing the error rate of wearing them. Through real-time posture recognition, it ensures that the left and right ears always receive hearing loss compensation parameters that match their degree of hearing loss, avoiding hearing damage or insufficient compensation caused by incorrect wearing.

[0046] Example 2 Based on the same inventive concept, this embodiment proposes a hearing aid, including a charging case and the hearing aid headphones of Embodiment 1 that can improve the comfort of use.

[0047] In one specific embodiment, the charging case has built-in fixed logical slots (slot 1 has a preset mode for the left ear, and slot 2 has a preset mode for the right ear). The core components of the charging case include: an MCU (used to store the slot mapping table and perform conflict detection), a Hall sensor (to detect whether the hearing aid earphone is in or out of the slot), and a Pogo Pin contact (used for command transmission and slot ID identification). An optical sensor is installed inside the hearing aid earphone to detect the wearing status, such as detecting whether the hearing aid earphone is worn in the ear canal by infrared light reflection; the microphone assembly is configured as an adaptive microphone array, that is, multiple microphone bodies are arranged in a specific geometric layout (such as linear / planar arrangement) to form a physical array, so as to allow for subsequent reconfiguration of microphone directionality (which can be adjusted by noise reduction algorithms, such as focusing on the front and suppressing rear noise).

[0048] See Figure 3Initially, the preset earphone placement mapping table is set as follows: earphone 1 = left ear mode, earphone 2 = right ear mode. When the user removes any hearing aid earphone (hereinafter referred to as A or B), the Hall sensor detects the removal signal and sends an interrupt signal to the MCU. The MCU reads the last operating mode of A before it was removed from the earphone via the Pogo Pin contact (e.g., A is in left ear mode). When the user puts the hearing aid earphone into any earphone (there may be cases where earphones are swapped), the Hall sensor detects that earphone A has been reinserted and sends an interrupt signal to the MCU. The MCU identifies the earphone placement via the Pogo Pin contact (e.g., Pin1 = earphone 1, Pin2 = earphone 2) and determines the target earphone placement (assuming A is placed in earphone 2). A reports its internally stored original mode (left ear mode) to the MCU via the Pogo Pin contact. If the original mode reported by A is inconsistent with the preset mode of the target earphone placement, a conflict detection is triggered.

[0049] The conflict detection process is as follows: An optical sensor detects whether B is wearing the hearing aid. If so (e.g., B is wearing it), mode switching is disabled, the original hearing aid mode is maintained (A remains in left ear mode), and the hearing aid positioning table is updated (Hearing A 2 → Left ear mode). A plays a "Left" prompt tone. If not (B is not wearing it), the MCU sends a SET_CHANNEL command (e.g., SET_CHANNEL RIGHT) to A via the Pogo Pin contact. Upon receiving this command, A's mainboard 6 switches the audio channel (left / right channels swap), reconfigures the microphone directionality, and updates the internal mode identifier. A plays a "Right" prompt tone. The MCU updates the hearing aid positioning table, binding hearing aid 2 to A's right ear mode (Hearing A 2 → A's right ear mode). When both A and B detect the insertion signal, the MCU sends stereo parameters (e.g., channel balance, delay compensation, etc.) to A and B via the Pogo Pin contact and synchronizes the mode configuration.

[0050] For example, in the initial state, earbud 1: A (left ear mode), earbud 2: B (right ear mode). After removing earbud A, it is placed in earbud 2. Earbud 2 is preset to right ear mode, and earbud A reports left ear mode, triggering conflict detection. If earbud B is not detected, the SET_CHANNEL RIGHT command is sent, earbud A switches to right ear mode, the earbud mapping table is updated: earbud 2 → A right ear mode, and earbud A plays a "Right" prompt tone.

[0051] In this embodiment, the user can place the hearing aid earphone anywhere, and the charging case can automatically correct the directionality of the sound channel and microphone, achieving zero interference when using one ear and rapid synchronization when both ears are idle, eliminating manual intervention and realizing a seamless "place and use" operation experience.

[0052] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. This disclosure is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims. Thus, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model is also intended to include these modifications and variations.
