Description

Technical Field

[0001] This utility model relates to the field of hearing aid technology, and in particular to a hearing aid ear stud. Background Technology

[0002] A hearing aid is a small amplifier. Its basic structure includes a microphone, battery, motherboard, and receiver. Its working principle is that the microphone collects external sound, converts it from analog signals to digital signals, and transmits them to the motherboard. The motherboard is a chip component that amplifies the received digital signals and transmits them to the receiver. The receiver converts these amplified digital signals back into analog signals (i.e., sound signals) and transmits them to the user's ear canal. By utilizing the user's residual hearing, the sound can be sent to the auditory center of the brain, thereby allowing the user to perceive the sound and bringing great convenience to the user.

[0003] Currently, some earring-style hearing aids have appeared on the market. These devices enhance concealment by embedding the microphone, battery, motherboard, and receiver within the earring shell. The earring shell is worn on the user's earlobe, and the sound from the receiver is transmitted to the user's ear canal through a sound tube extending outside the earring shell. However, due to the limited internal space of the earring shell, only small receivers can be used. Utility Model Content

[0004] The inventors discovered that small receivers, when transmitting sound through the ear canal via a sound tube, have a narrow frequency response range and suffer from severe low-frequency attenuation, making them unsuitable for users with moderate to severe hearing loss. In view of these problems, this invention is proposed to provide a hearing aid earring that overcomes or at least partially solves these problems.

[0005] The present invention discloses a hearing aid earring, comprising: an earring shell, a microphone, a battery, a motherboard, and a receiver;

[0006] The earring housing can be worn on the auricle, and the microphone, the battery and the motherboard are disposed inside the earring housing. The microphone and the battery are electrically connected to the motherboard respectively.

[0007] The receiver is placed outside the earring housing, and a wire connects the receiver to the earring housing. The receiver is electrically connected to the motherboard through the wire, and the receiver can be worn inside the ear canal.

[0008] Optionally, the hearing aid earring further includes an ear hook tube that can be hung in the concha cavity, one end of the ear hook tube being connected to the earring housing, and the other end of the ear hook tube being connected to the end of the wire away from the receiver.

[0009] Optionally, the end of the wire away from the receiver is provided with a connector plug, and the end of the ear hook tube away from the earring housing is provided with a connector socket adapted to the connector plug. The connector socket is electrically connected to the motherboard, and the connector plug is pluggable into the connector socket.

[0010] Optionally, the ear hook tube includes a straight tube section, a curved tube section, and a hook tube section connected in sequence. The end of the straight tube section away from the curved tube section is connected to the earring housing, and the end of the hook tube section away from the curved tube section is connected to the end of the wire away from the receiver.

[0011] Optionally, the ear hook tube is a shape memory metal flexible tube.

[0012] Optionally, the earring housing includes a first housing, a second housing, a connecting tube, and a fixing component for wearing the first housing and the second housing on the auricle. The two ends of the connecting tube are respectively connected to the first housing and the second housing. The main board and the microphone are disposed in the first housing, the battery is disposed in the second housing, and the wire is connected between the receiver and the first housing.

[0013] Optionally, the fixing component includes a first magnet disposed within the first housing and a second magnet disposed within the second housing.

[0015] Optionally, airbags and / or pads are respectively provided on the two opposite end faces of the first housing and the second housing.

[0016] Optionally, the connecting pipe is a U-shaped connecting hose.

[0017] The beneficial effects of the above-mentioned technical solutions provided by the embodiments of this utility model include at least the following:

[0018] In this application, the receiver is placed outside the earring shell, and a wire connects the receiver to the earring shell. The receiver is electrically connected to the motherboard via the wire, and the receiver can be worn inside the ear canal. Thus, by placing the receiver externally, a larger receiver with a wider frequency response range can be selected. Furthermore, since the receiver in this application is connected to the motherboard via a wire after being placed externally, the motherboard can directly transmit digital signals to the receiver. By directly transmitting sound into the user's ear canal through the receiver worn inside the ear canal, there is no attenuation of sound frequency, such as low-frequency attenuation, compared to a receiver that transmits sound signals through a sound tube. This method can meet the needs of users with moderate to severe hearing loss. Attached Figure Description

[0034] Currently available earring-style hearing aids improve concealment by embedding the microphone, battery, motherboard, and receiver within the earring shell. The earring shell is worn on the user's earlobe, and the sound from the receiver is transmitted to the user's ear canal through a sound tube extending outside the earring shell. However, due to the limited internal space of the earring shell, only small receivers can be used.

[0035] The inventors discovered that small receivers, when transmitted through a sound tube to the ear canal, have a narrow frequency response range and suffer from severe low-frequency attenuation, making them unsuitable for users with moderate to severe hearing loss. To address this issue, the inventors attempted to design a hearing aid earring and unexpectedly discovered that by externalizing the receiver and electrically connecting it to the motherboard via a wire, a larger receiver with a wider frequency response range could be selected. Furthermore, the motherboard's transmission of digital signals to the receiver via wire does not result in frequency attenuation, such as low-frequency attenuation, compared to the sound tube method, thus meeting the needs of users with moderate to severe hearing loss. Based on this, this invention provides a hearing aid earring. Figures 1 to 3 Specific embodiments of the hearing aid earrings provided by this utility model.

[0036] Please see Figures 1 to 3The hearing aid earring 100 provided by this utility model includes an earring shell 1, a microphone, a battery 2, a main board 3, and a receiver 4. The earring shell 1 can be worn on the auricle. The microphone, battery 2, and main board 3 are disposed inside the earring shell 1, and the microphone and battery 2 are electrically connected to the main board 3 respectively. The receiver 4 is placed outside the earring shell 1, and a wire 5 connects the receiver 4 to the earring shell 1. The receiver 4 is electrically connected to the main board 3 through the wire 5. The receiver 4 can be worn inside the ear canal.

[0037] In the technical solution provided by this utility model, by externalizing the receiver 4, a receiver 4 with a larger volume and a wider frequency response range can be selected. Moreover, after being externalized, the receiver 4 of this application is connected to the motherboard 3 via a wire 5. The motherboard 3 can directly transmit digital signals to the receiver 4. The sound is directly transmitted to the user's ear canal by the receiver 4 worn in the ear canal. Compared with the method of transmitting sound signals to the user's ear canal through a sound tube, there is no attenuation of sound frequency, such as low-frequency attenuation, which can meet the needs of users with moderate to severe hearing loss.

[0038] It should be noted that in existing earring-type hearing aids, the receiver 4 is embedded within the earring housing 1. Considering the limited internal space of the earring housing 1, only a small receiver 4 can be selected. Due to space constraints, the small receiver 4 typically uses a miniature balanced armature (BA) unit as the sound-generating component, which then transmits the sound to the user's ear canal through a sound tube. This results in a narrow frequency response range and severe low-frequency attenuation of the sound transmitted to the ear canal, making it difficult to meet the needs of users with moderate to severe hearing loss. In contrast, the receiver 4 of this application is external to the earring housing 1. Therefore, the size of the receiver 4 can be disregarded, and a larger receiver 4 with a wider frequency response range can be selected. The specific selection of the sound-generating component of the receiver 4 is not limited, as long as it can meet the needs of users with moderate to severe hearing loss. For example, the receiver 4 includes a moving iron horn 41 and an ear cap 42. The moving iron horn 41 is electrically connected to the end of the wire 5 away from the earring housing 1. The ear cap 42 is detachably connected to the sound outlet of the moving iron horn 41. The ear cap 42 can be directly worn in the user's ear canal, which not only improves the user's wearing comfort, but also allows the sound emitted by the moving iron horn 41 to be directly input into the ear canal without sound attenuation. The moving iron horn 41 used has a wide frequency response range, which can meet the needs of users with moderate to severe hearing loss.

[0039] Furthermore, the wire 5 consists of an insulating soft sheath and a conductor inside the insulating soft sheath. The wire 5 can be bent at any angle to accommodate the receiver 4 in different positions, making it easier for the user to wear the receiver 4 into the ear canal. It should be noted that there are no specific limitations on the length and diameter of the wire 5; they can be selected according to needs, as long as it ensures that the receiver can be worn inside the ear canal.

[0040] The following will describe, through exemplary illustration, a further detailed or improved process of the hearing aid earring 100, in order to further improve its efficiency, reliability, or for other improvement considerations.

[0041] In some embodiments, the hearing aid earring 100 further includes an ear hook tube 6 that can be hung in the concha cavity. One end of the ear hook tube 6 is connected to the earring housing 1, and the other end of the ear hook tube 6 is connected to the end of the wire 5 away from the receiver 4. When the earring housing 1 is worn on the earlobe at the lower part of the auricle, the ear hook tube 6 can be hung in the concha cavity. In this way, it can not only help fix the earring housing 1 to the auricle, but also reduce the suspension pressure on the earlobe, thereby improving the stability and comfort of wearing the hearing aid earring 100.

[0042] Specifically, the ear hook tube 6 includes a straight tube section 61, a curved tube section 62, and a hook tube section 63 connected in sequence. The end of the straight tube section 61 away from the curved tube section 62 is connected to the earring shell 1, and the end of the hook tube section 63 away from the curved tube section 62 is connected to the end of the wire 5 away from the receiver 4. Since there is a certain distance between the hook tube section 63, which is attached to the concha, and the earring shell 1 when the earring shell 1 is worn on the earlobe, the straight tube section 61 can extend the vertical distance of the hook tube section 63 relative to the earring shell 1. Since the concha is closer to the inner side of the ear than the earlobe, the curved tube section 62 allows the hook tube section 63 to be attached towards the concha, which is beneficial for wearing the ear hook tube 6.

[0043] In some embodiments, the end of the wire 5 away from the receiver 4 is provided with a connector plug 51, and the end of the ear hook tube 6 away from the earring housing 1 is provided with a connector socket 64 adapted to the connector plug 51. The connector socket 64 is electrically connected to the main board 3. For example, the connector socket 64 can be electrically connected to the main board 3 through a wire provided in the ear hook tube 6. The connector plug 51 is pluggable into the connector socket 64, so that different types or models of receivers 4 can be replaced according to user needs by plugging and unplugging the connector plug 51, thereby meeting the user's needs. In addition, when the receiver 4 malfunctions, the connector plug 51 can be unplugged to directly replace or repair the receiver 4 without having to remove the receiver 4 from the earring housing 1 for replacement or repair, which is more convenient. It can be seen that the ear hook tube 6 not only improves the stability and comfort of wearing, but also provides space for the connector socket 64. It should be noted that the connector plug 51 and the connector socket 64 are electrically connected, and the receiver 4 and the wire 5 are not limited to being integrally formed.

[0044] Considering that the shape of the concha varies among different users, the ear hook tube 6 is usually made of a soft tube. However, users do not wear the hearing aid earring 100 continuously during daily use, but wear it multiple times as needed. After multiple wears, the shape of the ear hook tube 6 is prone to irreversible plastic deformation, which is not conducive to the next wear. In some embodiments, the ear hook tube 6 is a memory metal soft tube. The memory metal soft tube can change its shape to adapt to different users through its flexibility, which improves its applicability. Moreover, under the action of memory metal, after the hearing aid earring 100 is removed, the ear hook tube 6 can return to its initial shape, which is conducive to the next wear. In addition, the memory metal soft tube is wrapped with silicone, which not only provides insulation and protection, but also has good skin-friendliness.

[0045] Currently, existing earring housings 1 are worn by attaching them to one side of the user's earlobe. Because the earring housing 1 contains various components of the hearing aid, it is relatively large and heavy, placing a considerable burden on the user's ear. In some embodiments, the earring housing 1 includes a first housing 11, a second housing 12, a connecting tube 13, and a fixing component for wearing the first housing 11 and the second housing 12 on the auricle. The first housing 11 and the second housing 12 are arranged at intervals relative to each other. The two ends of the connecting tube 13 are respectively connected to the first housing 11 and the second housing 12. The main board 3 and the microphone are located inside the first housing 11, the battery 2 is located inside the second housing 12, and the wire 5 connects the receiver 4 and the first housing 11. The first housing 11 and the second housing 12 are set independently. When wearing, the first housing 11 and the second housing 12 can be placed on both sides of the user's auricle and then worn through the fixing component. Since the microphone and the main board 3 are located in the first housing 11 and the battery 2 is located in the second housing 12, the weight of the hearing aid ear stud 100 is distributed on both sides of the auricle, reducing the burden on one side of the auricle and improving the user's wearing comfort. Moreover, by placing the relatively large battery 2 and the main board 3 in the first housing 11 and the second housing 12 on both sides of the auricle, the first housing 11 and the second housing 12 can be designed to be smaller and more concealed. It should be noted that, in order to facilitate the electrical connection between the receiver 4 and the main board 3, one end of the ear hook tube 6 is connected to the first housing 11, and the other end of the ear hook tube 6 is connected to the end of the wire 5 away from the receiver 4. In this way, the receiver 4 can be electrically connected to the main board 3 inside the first housing 11 through the wire 5 and the ear hook tube 6. In order to facilitate the user to wear the ear stud housing 1 on the earlobe, the ear hook tube 6 can be hung in the concha cavity. In this embodiment, the ear hook tube 6 and the connecting tube 13 are located on opposite sides of the first housing 11. In order to ensure that there is enough space between the first housing 11 and the second housing 12 to clamp on both sides of the earlobe, the connecting tube 13 is a U-shaped connecting hose. The U-shaped connecting hose can deform to provide sufficient range of motion for the first housing 11 and the second housing 12.

[0046] It is understood that the present invention does not impose specific limitations on the shape of the first housing 11 and the second housing 12, and can be selected according to requirements, as long as it can accommodate the microphone, the motherboard 3, and the battery 2. For example, both the first housing 11 and the second housing 12 are cylindrical. The first housing 11 includes a first bottom shell and a first end cap, with the first end cap detachably covering the first bottom shell and forming a first receiving cavity between the first bottom shell and the first end cap. The second housing 12 includes a second bottom shell and a second end cap, with the second end cap detachably covering the second bottom shell and forming a second receiving cavity between the second bottom shell and the second end cap. The motherboard 3 and the microphone are located within the receiving cavity of the first housing 11, and the battery 2 is located within the receiving cavity of the second housing 12. The first receiving cavity and the second receiving cavity are connected by a connecting pipe 13 to accommodate wiring for electrically connecting the battery 2 and the motherboard 3. The first end cap has a microphone hole 111 for microphone sound pickup.

[0047] It should be noted that the specific position of the earring housing 1 on the auricle via the fixing component is not limited; it can be worn on the upper part of the auricle's helix or on the lower part of the auricle's earlobe. For example, an ear post can be provided on one of the two opposite end faces of the first housing 11 and the second housing 12, and a clasp can be provided on the other side to cooperate with the ear post. After the ear post is passed through the ear hole on the earlobe, it is connected to the clasp, thereby enabling the first housing 11 and the second housing 12 to be worn on the earlobe.

[0048] Considering that some users do not choose to pierce their earlobes, in some embodiments, the fixing component includes a first magnet 14 disposed within the first housing 11 and a second magnet 15 disposed within the second housing 12. The magnetic attraction between the first magnet 14 and the second magnet 15 secures the first housing 11 and the second housing 12 to the auricle. In this way, users can wear the earring without piercing their ears, making the hearing aid earring 100 suitable for different groups, such as different age groups, different genders, and whether or not they have pierced ears. When wearing the hearing aid earring 100, the magnetic attraction between the first magnet 14 and the second magnet 15 is not specifically limited. Considering user comfort, the magnetic attraction can be between 0.4N and 0.48N after the hearing aid earring 100 is properly worn.

[0049] To provide sufficient magnetic force for a secure fit, please refer to [link / reference]. Figure 3 In some embodiments, the first magnet 14 is disposed between the inner wall of the motherboard 3 and the first housing 11, and the second magnet 15 is disposed between the inner wall of the battery 2 and the second housing 12. In this way, the distance between the first magnet 14 and the second magnet 15 can be minimized to enhance the magnetic attraction effect.

[0050] Considering that the two opposite end faces of the first housing 11 and the second housing 12 are end faces that contact the auricle, in some embodiments, airbags or pads are respectively provided on the two opposite end faces of the first housing 11 and the second housing 12, or both airbags and pads are provided. By having the airbags or pads contact the auricle, the wearing comfort can be improved. Moreover, it is worth mentioning that when the first magnet 14 and the second magnet 15 are combined to form a magnetic attraction structure, the airbags and pads can increase the contact area with the auricle compared to the end faces of the housings, thereby improving the stability of the hearing aid ear stud 100.

[0051] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
