Description

Technical Field

[0001] This invention relates to a hearing device. More specifically, this disclosure relates to a hearing device configured to be disposed in a user's ear, wherein the hearing device includes a sound path component. Background Technology

[0002] Hearing devices are electronic devices adapted to provide sound to a person or alleviate hearing loss. Hearing devices typically include multiple paths for, for example, guiding sound within the device. For instance, a hearing device may include a sound path to transmit incoming sound received by a microphone from the surrounding environment to the user's ear canal. As another example, a hearing device may include another sound path, namely a ventilation channel, to balance the pressure between the ear canal and the surrounding environment.

[0003] However, hearing devices that include such pathways may present challenges, such as design complexity and maintenance difficulty. Therefore, there is a need for an improved hearing device that includes such pathways to address or at least mitigate these challenges. Summary of the Invention

[0004] The purpose of this invention is to provide an improved hearing device that includes a simple, inexpensive, compact and airtight sound path system.

[0005] Another object of embodiments of the present invention is to provide an improved hearing device that includes a sound path system that is easy to maintain and therefore has a longer lifespan.

[0006] According to a first aspect of the invention, a hearing device is disclosed. The hearing device is configured to be disposed in a user's ear. The hearing device includes a sound path component. The sound path component includes a chamber disposed at a first end of the hearing device. The sound path component also includes a ventilation channel configured to ventilate the hearing device. The ventilation channel extends from the chamber to a second end of the hearing device. The ventilation channel has a first ventilation end located in the chamber and a second ventilation end located at the second end of the hearing device. The sound path component also includes an output transducer opening configured to connect to an output transducer. The output transducer opening is disposed in the chamber. The sound path component also includes a first opening disposed in the chamber and configured to point towards the user's ear canal when the user wears the hearing device in a desired position in the ear. The sound path component also includes a second opening disposed at the second end of the hearing device and configured to point towards the user's surroundings when the user wears the hearing device in a desired position in the ear. The second opening is located at the second ventilation end of the ventilation channel. The chamber, the ventilation channel, the output transducer opening, the first opening, and the second opening are in fluid communication with each other.

[0007] Therefore, the ventilation duct, first opening, second opening, and output transducer opening of the sound path system are connected to the chamber, i.e., the common chamber. This allows for a simple, inexpensive, user-friendly, and compact sound path component, as the sound path component includes a common chamber rather than a separate chamber. Furthermore, the ventilation duct, output transducer opening, first opening, and second opening are fluidly connected to each other via the chamber. Because the sound path component includes associated openings, sound leakage is prevented, thus achieving an airtight sound path component. Compared to sound path components with, for example, separate chambers, the airtight sound path component also allows for at least improved sealing. This is because, compared to separate chambers, the common chamber reduces sound leakage due to fewer components, i.e., fewer leakage paths. The output transducer opening can have, for example, a diameter of 1.4 mm.

[0008] Ventilation channels are designed to address the occlusion effect. An occlusion effect occurs when an object (such as a non-ventilated earmold) completely fills the outside of the ear canal. This traps bone conduction vibrations of a person's own voice when speaking, as well as sounds caused by movement / vibration during activities like walking, running, and chewing, in the space between the earmold tip and the eardrum. Normally, these vibrations escape through the open ear canal when people speak or chew, and they are unaware of these sound vibrations. However, when the ear canal is blocked, such as with an earmold, the vibrations are reflected back to the eardrum and increase the perceived loudness of a person's own voice or movements. The occlusion effect can increase low-frequency (typically below 500Hz) sound pressure levels in the ear canal by 20 dB or more compared to a completely open ear canal. Some people who wear hearing devices (such as hearing aids) experience a significant occlusion effect; these individuals may find their own voice unpleasant to hear and may also experience pressure or blockage in their ears when the earmold of the hearing device is inserted. Ventilation channels are configured to ventilate the hearing device. Ventilation channels eliminate or at least mitigate the occlusion effect. The ventilation channel allows for pressure equalization between the ear canal and the surrounding environment. The length of the ventilation channel along the longitudinal direction of the hearing device can be 2 mm. The ventilation channel, for example, along the transverse direction of the hearing device, can have a diameter of 0.8 mm.

[0009] Hearing devices may include domes. A dome may be attached to the housing of the hearing device to deliver sound into the user's ear canal.

[0010] Hearing devices may also include active occlusion cancellation to eliminate or further reduce the occlusion effect for hearing device users.

[0011] Active occlusion cancellation is a method of reducing unwanted sounds by adding a second sound specifically designed to eliminate the first sound. This can also be used in active noise control (ANC), also known as noise cancellation or active noise reduction (ANR).

[0012] Sound is a pressure wave, consisting of alternating periods of compression and rarefaction. The output transducers (e.g., receivers or speakers) in headphones that perform active occlusion cancellation emit sound waves with the same amplitude as the original sound but opposite phase (also known as out-of-phase). These waves combine to form new waves in a process called interference, effectively canceling each other out—an effect known as destructive interference.

[0013] Active occlusion cancellation can be achieved using analog circuitry or digital signal processing. An adaptive algorithm is designed to analyze the waveform of the original sound received in the input transducer (e.g., an in-ear microphone and / or bone conduction unit) in the ear, and then generate a constant-amplitude signal that either phase-shifts or inverts the polarity of the original signal based on a specific algorithm. This inverted signal (out-of-phase) can then be amplified, and the output transducer in the ear produces a sound wave with an amplitude proportional to the original waveform, thus creating destructive interference. This effectively reduces the volume of the perceived occlusion effect. The output transducer emitting the cancellation signal can be located where sound attenuation is needed, i.e., in the user's ear.

[0014] A sound path component is defined herein as a component that allows sound to pass through. Therefore, a sound path component includes a path through which sound can pass. A sound path component can be a closed or partially closed compartment configured to confine and guide sound in a fixed manner. The walls of the sound path component can be airtight and impermeable to both sound and air. Therefore, the sound path component can provide sound that is directed and / or originates from a first end and a second end of the hearing device. Except at the first and second ends of the hearing device, sound may not escape from the sound path component.

[0015] The first end of the hearing device here refers to one end of the hearing device that is configured to point towards the user's ear canal when the user wears the hearing device in the intended position in the ear.

[0016] The second end of the hearing device refers to the other end of the hearing device, which is configured to point towards the user's surroundings when the user wears the hearing device in the intended position in the ear. The second end can be the opposite end relative to the first end. The second end may not be the opposite end relative to the first end. The second end may be located on one side of the hearing device.

[0017] The chamber can be a partially enclosed compartment configured to confine and guide sound in a fixed manner. The walls of the chamber can be airtight and impermeable to both sound and air. Thus, the chamber can provide a space for sound to be directed and / or originate from a first end and a second end of the hearing device.

[0018] "Placement within a cavity" here means placement near, within, or adjacent to a cavity, such as above, below, or to one side of the cavity. The upper side of the cavity can be the side that points towards the user's ear canal when the user intends to place the hearing device in their ear. The lower side of the cavity can be the side that points towards the opposite side of the user's ear canal when the user intends to place the hearing device in their ear. One side of the cavity can be positioned, for example, between the upper and lower sides of the cavity.

[0019] The sound path component includes an output transducer opening configured to connect to an output transducer. The output transducer opening is disposed within a chamber. The output transducer opening can be an opening, channel, hole, through-hole, and / or a connection point between the chamber and the output transducer. The output transducer opening can have a circular shape. The output transducer opening can have a diameter, for example, 1.4 mm. The output transducer opening can have any other shape.

[0020] The sound path component includes a first opening disposed in a chamber. The first opening can be an opening, channel, hole, through-hole, and / or a connection point between the chamber and a first end of the hearing device when the user wears the hearing device in the intended position in the ear, such as a connection point with the user's ear canal. The first opening can have a circular shape. The first opening can have a diameter, for example, 3 mm. The first opening can have any other shape. A housing can be disposed around the first opening of the sound path component. The housing can be part of the hearing device, with a dome mounted thereon. For example, the housing can be part of the outer shell of the hearing device. The dome can be mounted onto the housing of the hearing device. A nozzle insert can be disposed inside the housing. The nozzle insert can be used to establish a connection from the sound path component to the user's ear. The nozzle insert can facilitate the use of a radial first sealing unit and / or a radial second sealing unit. The nozzle insert can facilitate cleaning the hearing device. The nozzle insert can collect, for example, earwax and can have a replaceable filter component for replacement when needed. The nozzle insert can have different configurations.

[0021] The sound path component also includes a second opening disposed at a second end of the hearing device. The second opening may be an opening, channel, hole, through-hole, and / or a connection point between the sound path component and the second end of the hearing device when the user wears the hearing device in the intended position in the ear, such as a connection point with the surrounding area. The second opening may have a circular shape. The second opening may have a diameter, for example, 0.8 mm or 2 mm. The diameter of the second opening may depend on the length of the sound path component and the frequencies to be filtered out. The second opening may have any other shape.

[0022] Hearing devices can include headphones, hearing aids, wearable devices, etc. They can also be in-the-ear (ITE) hearing devices, in-the-ear receiver (RIE) hearing devices, in-the-canal receiver (RIC) hearing devices, in-the-ear microphone and receiver (MaRIE) hearing devices, behind-the-ear (BTE) hearing devices including ITE units, or general-purpose hearing devices, etc.

[0023] The hearing device is configured to be worn by the user. The device can be placed in the user's ear, on the ear, in the ear canal, behind the ear, etc. A user can wear two hearing devices, one in each ear. The two devices can be connected, for example, wirelessly.

[0024] Hearing devices can be configured for audio communication, such as enabling a user to listen to media like music or radio, and / or enabling a user to make telephone calls. Hearing devices can be configured to perform hearing compensation for a user. Hearing devices can be configured to perform noise cancellation, etc.

[0025] Hearing devices may include a housing. The housing may include buttons for controlling one or more functions of the hearing device. The buttons may be in their designed position, intermediate position, or initial position, i.e., the position where the button is not activated, for example, by a user. When a user presses a button, the user can press the button down until it reaches its depressed position.

[0026] Buttons can be placed on or inside the housing.

[0027] The button can be located on a first surface of the housing. The first surface can be configured to point towards the surrounding environment when the hearing device is positioned at the intended location on the user's ear. The first surface can be on the outside of the housing.

[0028] An air gap may be provided in a first surface of the housing between the button and the housing. This air gap may be at least partially defined by an opening in the housing at which the button is disposed. The air gap may have a shape that at least partially corresponds to the shape of the button. The button may be circular, and the air gap may be annular, for example, in a shape surrounding the button.

[0029] The housing of a hearing device may be at least partially an enclosed entity comprising one or more electronic components of the hearing device. The housing may include an outer surface that can contact the user's skin. The housing may include an internal space in which the electronic components are disposed. The hearing device may include a printed circuit board (PCB), and electrical contacts may be arranged on the PCB to provide an electrical connection to a button to control one or more functions of the hearing device. Electrical contacts may be arranged on the PCB to provide an electrical connection to the button to control one or more functions of the hearing device when the button is activated by pressing it down to its depressed position. Protrusions on the button may be configured to contact the electrical contacts.

[0030] Hearing devices may include a Resonant Electronic Interface (RIE) unit. A RIE unit typically includes an earphone housing, a plug connector, and a wire / tube connecting the plug connector and the earphone. The earphone may include an in-ear housing, a receiver (e.g., a receiver configured for placement in a user's ear), and a closed dome. The dome supports proper placement of the earphone in the user's ear. The RIE unit may include an input transducer (e.g., a microphone or receiver), an output transducer (e.g., a speaker), one or more sensors, and / or other electronic devices. Some electronic components may be housed in the earphone, while others may be housed in the plug connector. The receiver may have different power levels, i.e., low power, medium power, or high power. The wire / tube provides electrical connection between the electronic components housed in the earphone within the RIE unit and the electronic components housed in the BTE unit. The wire / tube and the RIE unit itself may have different lengths.

[0031] Hearing devices may include output transducers, such as speakers or receivers. The output transducer may be part of the hearing device's printed circuit board (PCB). The output transducer may be disposed on the hearing device's PCB. The output transducer may not be part of the hearing device's PCB. The output transducer may be configured to be disposed on the hearing device's PCB. For example, the output transducer may be configured to be disposed at a designated location / area on the hearing device's PCB. The output transducer may be disposed through holes in the PCB.

[0032] Hearing devices may include a first input transducer (e.g., a microphone) to generate one or more microphone output signals based on received audio signals. The audio signal may be an analog signal. The microphone output signal may be a digital signal. Therefore, the first input transducer (e.g., a microphone) or an analog-to-digital converter can convert an analog audio signal into a digital microphone output signal. All signals can be sound signals or signals containing information about sound.

[0033] Hearing devices may include a signal processor. One or more microphone output signals can be provided to the signal processor for processing the one or more microphone output signals. The signals can be processed, for example, to compensate for a user's hearing loss or hearing impairment. The signal processor can provide a modified signal. All these components can be contained within the housing of an ITE unit or a BTE unit. Hearing devices may include a receiver or output transducer or a speaker or amplifier. The receiver can be connected to the output of the signal processor. The receiver can output the modified signal to the user's ear. The receiver or digital-to-analog converter can convert the modified signal (which is a digital signal) from the processor into an analog signal. The receiver can be contained within an ITE unit or headphones such as a RIE unit or a MaRIE unit. Hearing devices may include more than one microphone; an ITE unit or BTE unit may include at least one microphone, and a RIE unit may also include at least one microphone.

[0034] A signal processor for a hearing aid may include components such as amplifiers, compressors, and / or noise reduction systems. The signal processor can be implemented in a signal processing chip or on the PCB of the hearing aid. The hearing aid may also have filtering capabilities, such as compensation filters for optimizing the output signal.

[0035] Hearing devices may also include wireless communication units or chips (e.g., wireless communication circuits or magnetic induction chips) for wireless data communication interconnected with antennas, such as radio frequency (RF) antennas or magnetic induction antennas, for transmitting and receiving electromagnetic fields. The wireless communication unit, including a radio or transceiver, can be connected to the hearing device's signal processor and antenna for communication with one or more external devices, such as one or more external electronic devices, including at least one smartphone, at least one tablet computer, at least one hearing accessory device including at least one spouse microphone, remote control, audio testing equipment, etc., or in some embodiments, communication with another hearing device, such as another hearing device located in the other ear (typically in a binaural hearing device system).

[0036] In some embodiments, the sound path component may further include an input transducer opening configured to connect to a first input transducer. The input transducer opening may be disposed within a chamber. The input transducer opening may be in fluid communication with the chamber, a ventilation channel, an output transducer opening, the first opening, and the second opening.

[0037] Therefore, the input transducer opening can also be connected to the chamber, i.e., the common chamber. Thus, the input transducer opening can be fluidly connected to the ventilation channels, first opening, second opening, and output transducer opening of the sound path system via the common chamber. This, in turn, allows for simpler, cheaper, more user-friendly, more compact, and improved hermetic sound path components. Furthermore, the improved hermetic sound path system allows for a more improved seal compared to sound path components with separate chambers. The input transducer opening can have, for example, a diameter of 1.4 mm.

[0038] Therefore, the sound path component may include an input transducer opening configured to connect to an input transducer. The input transducer opening may be disposed within a chamber. The input transducer opening may be an opening, channel, hole, through-hole, and / or a connection point between the chamber and the input transducer. The input transducer opening may have a circular shape. The input transducer opening may have a diameter, for example, 1.4 mm. The input transducer opening may have any other shape.

[0039] The input transducer can be an input transducer configured for active occlusion cancellation. The input transducer opening can be located within the chamber, such as on the upper side, lower side, or side of the chamber. The hearing device may include other input transducers. These other input transducers can be configured to point towards the user's surroundings when the user places the hearing device in the intended position in the ear. For example, the other input transducer can be located at a second end of the hearing device. The other input transducers can record and amplify sounds from the surroundings. These recorded sounds can be acoustically reproduced, for example, by a small amplifier in the hearing device, thereby mitigating hearing loss in such a way that frequencies imperceptible to the human can be amplified to levels above the human's hearing threshold at those frequencies.

[0040] In some embodiments, the chamber may have multiple sides. An output transducer opening may be located on a first side of the chamber. An input transducer opening may be located on a second side of the chamber. This allows for flexible sound path components, such as those that can be designed in a flexible manner. The chamber may have multiple sides, such as two sides, three sides, four sides, etc. These sides may be the walls of the chamber. The first side of the chamber may be the upper side, the lower side, or a side perpendicular to the upper and / or lower side of the chamber. Unlike the first side of the chamber, the second side of the chamber may also be the upper side, the lower side, or a side perpendicular to the upper and / or lower side of the chamber. The first and second sides of the chamber may be arranged opposite each other. The first and second sides of the chamber do not necessarily need to be arranged opposite each other. The first side of the chamber may be arranged at an angle relative to the second side of the chamber, i.e., the normal plane of the first side of the chamber may be arranged at an angle relative to the normal plane of the second side of the chamber. This angle can be any angle, such as 90 degrees.

[0041] In some embodiments, the chamber may have multiple sides, with the output transducer opening and the input transducer opening arranged on a first side of the chamber. Therefore, both the input and output transducers can be arranged on the same side of the chamber. This, in turn, allows for more flexible sound path components, enabling them to be designed in a more flexible manner.

[0042] In some embodiments, the sound path component can be a single, integral component. In other words, the sound path component can be made from a single part. Therefore, the sound path component can be configured in a simpler manner. For example, the sound path component can be manufactured by molding. Thus, a single-piece sound path component can facilitate such molding, for example, allowing for improved molding, such as easier, cheaper, and faster molding.

[0043] Alternatively, the sound path component may not be a single, integrated component. For example, the sound path component may be a two-part component or a multi-part component.

[0044] In some embodiments, the sound path component in a hearing device can be replaceable. This, in turn, allows for an increase in the lifespan of the hearing device by replacing the sound path component when necessary. In the case of a one-piece sound path component, the replaceability of the sound path component allows for improved maintenance, repair, or replacement of the sound path component. This is because, compared to a sound path component comprising several parts, only the one-piece sound path component needs to be replaced, for example.

[0045] In some embodiments, at least a portion of the sound path component may be made of a flexible material. The flexible material may be, for example, a soft material. This, in turn, allows for a more compact hearing device, as the sound path component can be bent, for example, to fit into the housing of the hearing device. For example, ventilation channels may be made of a flexible material. Furthermore, the flexible material allows for flexible mounting of the sound path component, as it can be easily fitted into the housing of the hearing device. Examples of flexible materials (e.g., soft materials) may include silicone or thermoplastic elastomers (TPEs). Alternatively, the sound path component may be made of flexible materials such as soft materials and non-flexible materials such as rigid materials. Examples of non-flexible materials (e.g., rigid materials) may include rigid plastics, such as ABS.

[0046] In some embodiments, the hearing device may include a first sealing unit for an output transducer opening and a second sealing unit for an input transducer opening. The first and second sealing units may be configured to seal the output transducer opening and the input transducer opening, respectively. Thus, the first and second sealing units can provide improved sealing of the sound path components, i.e., the first and second sealing units can prevent or at least reduce sound leakage from the input and output transducer openings. The first and / or second sealing units may be radial sealing units, such as annular sealing units. Such radial sealing units may be radially flexible, i.e., they can radially seal the output and input transducer openings. When the first and / or second sealing units are radial sealing units(s), such radial sealing units(s)(s) can generate some tension in the radial direction. The first and / or second sealing units may also be axial sealing units. Such axial sealing units may be axially flexible, i.e., they can axially seal the output and input transducer openings. When the first sealing unit and / or the second sealing unit is one or more axial sealing units, such axial sealing units can be used as spring elements that generate some tension in the axial direction, and thus facilitate, for example, sealing of hearing devices. The first sealing unit and / or the second sealing unit can be made of, for example, silicone resin.

[0047] In some embodiments, the hearing device may include a dome at a first opening. The hearing device may include a third sealing unit between the dome and the first opening. The third sealing unit may be a radial sealing unit or an axial sealing unit. The dome may be made of an elastic material that conforms to the ear canal during use. Compared to, for example, an earplug, the dome may be lighter and more comfortable. The dome may have a closed configuration. This closed configuration can provide the function of a closed earplug without ventilation holes.

[0048] In some embodiments, the dimension of the chamber along the first direction can be in the range of 2-10 mm. The dimension of the chamber along the second direction can be in the range of 2-10 mm. The chamber may include the shape of a sphere with a diameter of, for example, 2.5 mm. The chamber may have a diameter of 13 mm. 3 The volume. The first direction can be a direction extending from the first end of the hearing device to the second end of the hearing device. The first direction can extend along the longitudinal direction of the hearing device. The second direction can be a direction extending in the opposite direction to the first direction. The second direction can extend along the transverse direction of the hearing device.

[0049] The present invention relates to various aspects, including the hearing devices and systems described above and below, and corresponding device components, each producing one or more benefits and advantages described in conjunction with the first mentioned aspects, and each having one or more embodiments corresponding to the embodiments described in conjunction with the first mentioned aspects and / or disclosed in the appended claims.
