Description

Technical Field

[0001] This utility model relates to a hearing device with a radio communication apparatus. The radio communication apparatus has an antenna with two feed points. Background Technology

[0002] Hearing loss patients typically use hearing aids. These devices usually employ a microphone, or electromechanical sound sensor, to convert ambient sound into electrical signals (audio / audio signals), which are then detected. The acquired electrical signals are processed by an amplification circuit and then transmitted into the ear canal via a separate electromechanical transducer, often in the form of a stethoscope. In most cases, further processing of the detected audio signals is required, typically using a signal processor with an amplifier circuit. Here, the amplification function is adjusted according to the hearing loss of the user.

[0003] However, in some cases, it is preferable to use a handset to output a different audio signal, such as transmitting it wirelessly to a hearing aid. The audio signal is then provided by another device, such as a television. This allows the user to directly perceive the audio signal corresponding to the movie output by the television set, without being disturbed by ambient noise. Other types of hearing aids, including hearing devices, can also reproduce the audio signal. In this case, the hearing aid can be designed as a wireless headset or earpiece, etc.

[0004] Control commands can also be transmitted to the hearing aid using radio communication devices. If the hearing aid is designed as an assistive hearing device, the user can select specific settings to adapt the playback settings to various situations faced by the user. In this case, the hearing aid does not require direct manual operation, and therefore can be designed to be relatively small.

[0005] To avoid unnecessary environmental interference, radio communication devices must operate within a defined standard frequency range. This allows the use of existing components of hearing devices or other devices that communicate with them. Examples of such standards include Bluetooth, WLAN, or UWB (“Ultra-Wideband”). Different standards use different frequencies.

[0006] Because their respective energy storage devices are relatively small, hearing devices provide limited energy. To ensure that the energy required for the operation of radio communication devices is low, the resonant frequency of the radio communication device's antenna must be essentially the same as the frequency used. If different standards are to be supported by the hearing device, two radio communication devices would be required, each with a different resonant frequency for its antenna, which increases weight, manufacturing costs, and required installation space. Utility Model Content

[0007] The problem to be solved by this invention is to provide a particularly suitable hearing device, which in particular can reduce weight, manufacturing costs and / or size.

[0008] The technical problem described herein is solved by a hearing device with a radio communication apparatus, the radio communication apparatus having an antenna with two feed points connected to a control unit, wherein the antenna has a first loop extending between the two feed points and a second loop extending between the two feed points.

[0009] Hearing devices may be, for example, headphones or headphones. Alternatively, hearing devices may be headsets, truly wireless headphones, hearing devices, or personal sound amplifiers. However, hearing devices are particularly preferred to be hearing aids. Hearing aids are used to support patients with hearing loss. In other words, a hearing aid is a medical device that compensates for, for example, partial hearing loss. Hearing aids may be, for example, in-canal receiver (RIC) hearing aids, in-ear hearing aids (such as in-ear hearing aids), in-the-canal (ITC) hearing aids, or completely-in-the-canal (CIC) hearing aids, hearing glasses, pocket hearing aids, bone conduction hearing aids, or implantable hearing aids. In another alternative design, the hearing device is a behind-the-ear (BTE) hearing aid worn behind the ear.

[0010] Hearing devices are designed and configured to be worn on the human body. In other words, hearing devices preferably include a holding device by which they can be secured to the human body. If the hearing device is a hearing aid, it is designed and configured, for example, to be positioned behind the ear or within the ear canal. Hearing devices are particularly wireless and are designed and configured to extend at least partially into the ear canal. Hearing devices particularly preferably include a power storage device through which power is provided.

[0011] Hearing devices preferably include microphones for detecting sound. During operation, ambient sound, or at least a portion thereof, is detected via the microphone. The microphone is, in particular, an electromechanical sound transducer. The microphone may have, for example, a single microphone unit or multiple microphone units that interact with each other. Each microphone unit suitably has a diaphragm that is vibrated by sound waves, wherein the vibration is converted into an electrical signal by a corresponding collecting device, such as a magnet moving in a coil. Thus, an audio signal, based on sound waves impacting the microphone device, can be detected by the corresponding microphone unit. The microphone unit is particularly designed to be unidirectional. Suitablely, the microphone is at least partially mounted within the housing of the hearing device and is therefore at least partially protected.

[0012] Suitablely, the hearing device has an earpiece for transmitting an output signal. Here, the output signal is particularly an electrical signal. The earpiece is an electromechanical sound transducer, preferably a loudspeaker. Depending on the design of the hearing device, in a given state, the earpiece is at least partially located within the ear canal of the wearer, or at least acoustically connected to the wearer. Furthermore, the wearer is also referred to as a user, hearing device wearer, or user. The hearing device is primarily used to transmit an output signal via the earpiece, wherein speech is generated. In other words, the main function of the hearing device is to emit an output signal. Here, the output signal is generated, at least partially, based on the sound detected by the microphone. Alternatively, the output signal is generated based on a transmitted data signal (audio signal), or for which a data signal is used. In other words, the output signal is generated, particularly based on a streaming process, or in this case, the playback of a specific sample.

[0013] Hearing devices suitably include a signal processor, which may suitably constitute a signal processing unit or at least be a component of a signal processing unit. However, hearing devices at least suitably include a corresponding signal processing unit. The signal processor is designed, for example, as a digital signal processor (DSP) or an analog component. The signal processor, in particular, adjusts the (audio) signal generated / transmitted by a possible microphone, preferably according to the hearing loss of the wearer of the hearing device. When the signal processor is designed as a digital signal processor, a digital-to-analog converter can be suitably placed between the microphone and the signal processing unit, such as the signal processor. The signal processor is configured, in particular, according to a set of parameters. Here, the amplification is set in different frequency ranges by means of the parameter set in order to process the audio signal generated / transmitted by the microphone according to specific specifications, especially according to the hearing loss of the wearer of the hearing device. Particularly preferably, the hearing device also includes an amplifier, or the amplifier is at least partially constituted by the signal processor. The amplifier is, for example, signal-technically connected upstream or downstream of the signal processor.

[0014] The hearing device also includes a radio communication device, which is suitably connected to a signal processing unit and / or possibly an earpiece. The radio communication device is particularly used here to receive audio / data signals to be transmitted and / or control parameters / settings of the possible signal processing device or other control devices of the hearing device. Alternatively or in combination with the foregoing, the radio communication device is also particularly used to transmit data from the hearing device to other devices.

[0015] A radio communication device includes an antenna with two feed points. The antenna is suitably configured and designed to transmit electromagnetic waves when a voltage, preferably an alternating voltage, is applied to the two feed points and / or a specific current is conducted through the feed points. The two feed points are connected to a control unit. Preferably, a voltage can be applied to the two feed points, and / or a specific current can be conducted through them. In this case, the control unit can be designed, in particular, as a so-called transmitter. Alternatively or in combination, the voltage at the two feed points can be detected by means of the control unit. In this case, the control unit can be designed, in particular, as a receiver. Particularly preferred is that the control unit can function as both a transmitter and a receiver, and is therefore designed as a transceiver.

[0016] The antenna has a first loop extending between two feed points, which is particularly made of a conductor. Therefore, the antenna is designed in the form of a dipole, especially a folded dipole. For example, the first loop is made of a wire or a flat strip. Furthermore, the antenna also has a second loop extending between the two feed points. The second loop is also particularly made of a conductor, such as a flat strip or a wire. The antenna is suitably a loop antenna, preferably a so-called "balanced-fed antenna".

[0017] Since the two loops extend between the two feed points, they are electrically in contact with each other and connected in parallel. The two loops are suitably formed integrally with each other. For example, the loops can be formed by bending sheet metal or similar materials, and for example, by stamping and bending. Alternatively, the loops can be formed by a circuit board, preferably a flexible circuit board. This allows for a relatively space-saving arrangement within the hearing device.

[0018] The two loops are suitably of different lengths. This allows the antenna to generate two distinct resonant frequencies, one of which is not an integer multiple of the other. Instead, the two resonant frequencies are essentially free. Therefore, the radio communication device can operate at different frequencies, each corresponding to one of the resonant frequencies, or only separated by a small frequency difference. Consequently, the power requirements are relatively low, and operating frequencies suitable for a defined standard can be used separately. Two radio communication devices are not required; only a single control unit is needed to control the corresponding matched antenna. This reduces manufacturing costs and weight. Furthermore, since only the radio communication device is needed and the antenna has two loops, its arrangement is more flexible, thus reducing space requirements. Therefore, the hearing device can be designed to be relatively small.

[0019] The antenna is specifically designed as a so-called differential antenna. The antenna may include additional loops, for example. However, the antenna is preferably composed of only two loops, thereby further reducing space requirements and weight. The two loops are suitably constructed from a common flexible circuit board, thus simplifying assembly. This also reliably prevents accidental connection (short circuit) between the two loops and the two feed points.

[0020] For example, a circular structure can be formed by two loops. However, it is particularly preferred that the two loops are essentially C-shaped, at least when unfolded. Here, the first loop suitably surrounds the second loop. The first loop is particularly longer than the second loop, and therefore has a lower resonant frequency. Due to this surrounding, the space requirement is also reduced. If the two loops are constructed from a common component, such as a flexible circuit board, the material requirements are also reduced.

[0021] Suitablely, the length of the first loop is between 0.5 and 1.25 times the first operating wavelength. Here, the first operating wavelength corresponds to the first operating frequency, which is equal to the quotient of the electromagnetic wave phase velocity and the first operating frequency. Due to the presence of the first loop, the antenna has a first resonant frequency, which is equal to the quotient of the electromagnetic wave phase velocity and the length of the first loop. Due to the choice of the first loop length, the first resonant frequency essentially corresponds to the first operating frequency, i.e., the length of the first loop is exactly equal to the first operating wavelength. Due to the existing tolerance, i.e., the length is chosen between 0.5 and 1.25 times the first operating wavelength, the first resonant frequency can be (slightly) offset relative to the first operating frequency. However, even with a slight offset, the energy required for antenna operation is relatively low. However, due to the flexibility in length selection, the antenna design freedom is increased, thus allowing for relatively efficient use of available space. In this way, the antenna can also be optimized to meet further requirements, thereby simplifying the antenna construction / design.

[0022] The first operating frequency should be greater than 1 GHz, preferably less than 5 GHz. The first operating frequency is suitable between 1.5 GHz and 3 GHz. The first operating frequency is suitable between 2.4 GHz and 2.5 GHz. Therefore, the first operating wavelength is approximately 12.5 cm. Thus, the space requirement for the first loopback is not excessive. However, the radio communication device can also be designed according to the Bluetooth standard or the "Bluetooth Low Energy" standard. When selecting the first operating frequency, the radio communication device will specifically operate according to this standard.

[0023] Alternatively or in combination, the length of the second loop is between 0.5 and 1.25 times the third operating wavelength corresponding to the third operating frequency of the antenna. Here, the third operating frequency is particularly greater than the possible first operating frequency. This length of the second loop generates a third resonant frequency for the antenna, which substantially corresponds to the third operating frequency. Thus, the radio communication device can operate at a relatively energy-efficient frequency. Here, the length of the second loop can be varied to some extent depending on the selection of the third operating wavelength between 0.5 and 1.25 times. This allows the length of the second loop to be adjusted according to other requirements, whereas it would not be possible if the length of the second loop were fixed. Therefore, this increases flexibility.

[0024] The third operating frequency is preferably greater than 3 GHz or 5 GHz, and particularly less than 20 GHz. The third operating frequency is preferably between 7 GHz and 9 GHz. The third operating frequency is preferably between 7.75 GHz and 8.25 GHz. Therefore, the third operating wavelength is approximately 3.8 cm, resulting in relatively small space requirements for the second loop. Depending on the selected third operating frequency, the radio communication device can operate according to the UWB standard (“Ultra-Wideband” standard).

[0025] Particularly preferred is that the lengths of the first and second loops are chosen such that the second resonant frequency of the antenna is between 5 GHz and 6 GHz. The second resonant frequency suitably corresponds to, or is slightly offset from, the second operating frequency, particularly by less than 0.5 GHz, 0.2 GHz, or 0.1 GHz and / or less than 10%, 5%, or 1%. Therefore, the radio communication device can operate at a second operating frequency conforming to the WLAN standard.

[0026] Suitablely, the lengths of the two loops can be determined through optimization algorithms or analysis. The length of the first loop is preferably between 0.5 and 1.25 times the first operating wavelength, and the length of the second loop is between 0.5 and 1.25 times the third operating wavelength. Since the lengths of each loop can be varied within their respective constraints, the second resonant frequency can be selected between 5 GHz and 6 GHz. In other words, an optimization problem is formed where the constraints applicable to the first or third operating wavelength are two parameters, namely the lengths of the respective loops, and where the second resonant frequency is optimized such that it is between 5 GHz and 6 GHz. Optimization can be performed here, for example, using heuristic or analytical methods. According to this design, the radio communication device can operate at three different operating frequencies, where the two loops always use the same antenna. If the first operating frequency is between 2.4 GHz and 2.5 GHz, the second between 5 GHz and 6 GHz, and the third between 7.75 GHz and 8.25 GHz, the radio communication device conforms to Bluetooth, WLAN, and UWB standards. This allows for relatively flexible use of hearing devices, requiring only a single control unit and a single antenna.

[0027] The control unit is specifically designed for the antenna to operate at one of several operating frequencies. Here, the control unit can operate at, for example, all possible operating frequencies, such as a first operating frequency, a second operating frequency, and a third operating frequency. Here, the antenna preferably operates temporarily, particularly according to current requirements, at one of the different operating frequencies. A switching unit or similar component is suitably provided, by means of which the desired operating frequency can be selected. Alternatively, the control unit may be configured, for example, to operate at only a small number of operating frequencies, such as two or only one. Here, for example, which operating frequencies can / should be used are permanently stored in the control unit, and appropriate programming is suitably performed for this purpose. Therefore, the radio communication device can be used with a relatively large number of hearing devices, where no hardware replacement / adjustment is required, and where different tasks are performed by means of the radio communication device. This results in a batch effect, thereby reducing manufacturing costs. Attached Figure Description

[0034] In all the accompanying drawings, corresponding parts are given the same reference numerals. Detailed Implementation

[0035] Figure 1 A hearing device 2 in the form of a hearing aid is schematically shown, configured and designed to be worn behind the ear by a wearer (user, hearing aid wearer, user). In other words, it is a behind-the-ear hearing aid. The hearing device 2 includes a housing 4 made of plastic. Within the housing 4 is arranged a microphone 6 having two sound transmission units 8, each designed as an omnidirectional electromechanical sound transducer. By changing the time offset between the sound signals measured by the omnidirectional sound transmission units 8, the directional characteristics of the microphone 6 can be altered, thereby achieving a directional microphone.

[0036] The two sound transmission units 8 are technically coupled to a signal processing unit 10, which includes an amplifier circuit and a signal processor (not shown in detail). The signal processing unit 10 is also composed of circuit elements, such as electrical and / or electronic components. The signal processor is a digital signal processor (DSP) and is connected to the sound transmission units 8 via an analog-to-digital converter (not shown in detail).

[0037] The earpiece 12 is technically connected to the signal processing unit 10. During operation, the earpiece 12, acting as an electromechanical sound transducer, converts the (electrical) signal provided by the signal processing unit 10 into output sound, i.e., into sound waves. These sound waves are sent into the sound guide tube 14, one end of which is fixed to the housing 4. The other end of the sound guide tube 14 is surrounded by a convex cap 16, which, in its normal state, is positioned in the ear canal (not shown in detail) of the wearer of the hearing device 2. A portion of the electrical energy is transmitted from the signal processing unit 10 to the microphone 6 and the earpiece 12.

[0038] The hearing device 2 also includes a radio communication device 20, which is technically connected to and operated by the signal processing unit 10. Power is also supplied to the signal processing unit 10. The radio communication device 20 receives control commands, thereby changing the operating mode of the signal processing unit 10. Thus, the amplification at a specific frequency can be changed by means of control commands, so that the signal output by the earpiece 12 adapts to the wearer's hearing loss.

[0039] The radio communication device 20 can also receive information such as updates from the signal processing unit 10. Furthermore, the radio communication device 20 can also be used to output operating status, for example, to another connected device, such as a smartphone, so that the user can access the operating status via the smartphone.

[0040] In another alternative, the radio communication device 20 can be used to communicate with other hearing devices, especially those of the same construction, which together form a hearing device system, with each hearing device 2 belonging to one of the wearer's ears. Therefore, the hearing device system is designed to be binaural. Here, the output sound can be adapted to each other through each earpiece 12, thereby providing the user with a sense of space.

[0041] Alternatively or in combination, the radio communication device 20 is used to receive electrical signals containing audio information. For example, this electrical signal is processed by the signal processing unit 10, or at least transmitted to the earpiece 12, so that the output sound corresponds to the signal received by means of the radio communication device 20. In this case, the signal provided by the microphone 8, for example, is not transmitted to the earpiece 12, or these signals are superimposed. This allows audio information to be provided to the user of the hearing device, especially in the absence of background noise.

[0042] Different applications require different communication standards, namely Bluetooth, WLAN, and UWB. These standards all use different frequencies of radio waves to avoid or at least reduce overlap / interference. Therefore, in the Bluetooth standard, the first operating frequency is between 2.4 GHz and 2.5 GHz. In the WLAN standard, the second operating frequency is between 5 GHz and 6 GHz. In the UWB standard, the third operating frequency is between 7.75 GHz and 8.25 GHz.

[0043] To achieve different standards, radio communication devices 20, such as Figure 2 The diagram shows a control unit 22, which comprises a plurality of electrical and / or electronic components not shown in detail. The antenna 24 operates via the control unit 22 and has two feed points 26. These two feed points are electrically connected to the control unit 22, and the control unit 22 can apply alternating voltage to / detect the voltage at the feed points 26 at their respective operating frequencies.

[0044] Antenna 24 has a first loop 28 and a second loop 30, each of which is constructed of a generally C-shaped conductor and faces at its ends toward two feed points 26. In other words, feed points 26 are adjacent to each loop 28 and 30 at their ends, and the two loops 28 and 30 are in electrical contact with each other at their ends. The two loops 28 and 30 are made of the same material and are integral with each other, thus facilitating assembly.

[0045] Figure 3 A cross-sectional side view of the hearing device 2 is shown, in which the housing 4 is omitted. A first loop 28 surrounds a second loop 30 on its outer periphery, and the edges of the two loops 28 and 30 curve according to the outer contour of the housing 4. Figure 3 Only screenshots are shown.

[0046] The length of the first loop 28 is approximately 12.5 cm, while the length of the second loop 30 is approximately 3.8 cm. To accommodate the first loop 28 within the housing 4, the first loop has several protrusions and is thus designed in a at least partially meandering shape. The length of the first loop 28 is 0.5 to 1.25 times the first operating wavelength corresponding to the first operating frequency. Here, the operating wavelength is the quotient of the electromagnetic wave phase velocity and the corresponding operating frequency.

[0047] like Figure 4 As shown, the length of the first loop 28 results in the first resonant frequency 32 of the antenna 24. The attenuation of the antenna 24 at the corresponding frequency is shown here. When the antenna 24 operates at the first resonant frequency 32, each electromagnetic wave can only be received / transmitted through the first loop 28, thus reducing energy demand. The second loop 30, even if electrically connected to the feed point 26, is almost unusable. Due to the chosen length of the first loop 28, the first resonant frequency 32 is essentially equal to the first operating frequency, making the operation of the radio communication device 20 relatively energy-efficient at the first operating frequency.

[0048] The length of the second loop 30 is between 0.5 and 1.25 times the third operating wavelength corresponding to the third operating frequency. This produces the third resonant frequency 34, at which the transmission and reception of electromagnetic waves occur essentially only through the second loop 30. The third resonant frequency 34 is essentially equal to the third operating frequency.

[0049] Antenna 24 also has a second resonant frequency 36. At the second resonant frequency, corresponding electromagnetic waves are transmitted and received through two loops 28 and 30, particularly by forming standing waves in the conductors of antenna 24. Therefore, both loops 28 and 30 are used for transmitting and receiving electromagnetic waves. The second resonant frequency 36 is located between the first resonant frequency 32 and the third resonant frequency 34, and the second resonant frequency 36 is determined by the lengths of the first and second loops 28 and 30. Here, the lengths of the first and second loops 28 and 30 are selected within the corresponding limits specified by the associated operating frequency, so that the second resonant frequency 36 of antenna 24 is between 5 GHz and 6 GHz, and substantially corresponds to the second operating frequency.

[0050] In summary, antenna 24 has three resonant frequencies 32, 34, and 36, which correspond substantially to one of the multiple operating frequencies of radio communication device 20. Therefore, communication via radio communication device 20 is relatively energy-efficient and complies with relevant standards.

[0051] Figure 5 A block diagram of the radio communication device 20 is shown. The control unit 22 has three standard components 38, thereby generating and / or analyzing electrical signals generated according to one of the Bluetooth, WLAN, or UWB standards, the electrical signals having frequencies belonging to the corresponding standard. Furthermore, a switching unit 40 is provided, through which the standard components 38 are connected to the antenna 24, i.e., the two feed points 26. Depending on the configuration of the switching unit 40, only one standard component 38 is electrically contacted with the antenna 24 to enable signal reception / feeding. Therefore, the standard used by the radio communication device 20 can be selected by means of the switching unit 40, especially the standard within a defined time period. Thus, in this variant, the hearing device 4 uses a total of three standards, depending, for example, on the operating mode.

[0052] Figure 6 A variant of the radio communication device 20 is shown, in which only one standard component 38 is connected to the antenna 24. In this variant, the standard and the operating frequency used are stored in the corresponding standard component 38, for example, through programming. This is then used continuously during the operation of the hearing device 2. In this way, the radio communication device 20 can be used with a large number of different hearing devices 2 without hardware adjustments, and each hearing device 2 has different functions.

[0053] exist Figure 5In a modified version of the illustrated scheme, not shown in detail, only two standard components 38 exist, thus the wireless communication device 20 uses two different standards. These standards can also be specified, for example, through programming. Regardless of the specific number of standard components 38 and / or the presence or absence of the switching unit 40, the control unit 22 is always designed to operate the antenna 24 at at least one or more operating frequencies.

[0054] This invention is not limited to the foregoing embodiments. Instead, those skilled in the art can derive other variations of this invention, as long as they do not depart from the technical solution of this invention. In particular, all the individual technical features described in the various embodiments can be combined with each other in other ways, as long as they do not depart from the technical solution of this invention.
