Definitions

the present invention relates to a hearing apparatus with a switching regulator including an inductor and a transmitter including an antenna for wireless electromagnetic transmission of data.
a hearing device is understood here to mean any device for sound output which can be worn on or in the ear, in particular a hearing device, a headset, headphones and the like.
Hearing aids are portable hearing aids that are used to care for the hearing impaired.
different types of hearing aids such as behind-the-ear hearing aids (BTE), hearing aid with external receiver (RIC: receiver in the canal) and in-the-ear hearing aids (IDO), e.g. Concha hearing aids or canal hearing aids (ITE, CIC).
BTE behind-the-ear hearing aids
RIC hearing aid with external receiver
IDO in-the-ear hearing aids
ITE canal hearing aids
the hearing aids listed by way of example are worn on the outer ear or in the ear canal.
bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. The stimulation of the damaged hearing takes place either mechanically or electrically.
Hearing aids have in principle as essential components an input transducer, an amplifier and an output transducer.
the input transducer is usually a sound receiver, z. As a microphone, and / or an electromagnetic receiver, for. B. an induction coil.
the output transducer is usually used as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z. B. bone conduction, realized.
the amplifier is usually integrated in a signal processing unit. This basic structure is in FIG. 1 shown using the example of a behind-the-ear hearing aid. In a hearing aid housing 1 for carrying behind the ear are one or more microphones 2 to Built-in sound recording from the environment.
a signal processing unit 3 which is also integrated in the hearing aid housing 1, processes the microphone signals and amplifies them.
the output signal of the signal processing unit 3 is transmitted to a loudspeaker or earpiece 4, which outputs an acoustic signal.
the sound is optionally transmitted via a sound tube, which is fixed with an earmold in the ear canal, to the eardrum of the device carrier.
the power supply of the hearing device and in particular of the signal processing unit 3 is carried out by a likewise integrated into the hearing aid housing 1 battery. 5
the cell voltage which is higher than, for example, alkaline-manganese batteries or zinc-air batteries, must be reduced if the technology designed for 1.5 volt cells continues to be used should.
This technology which is currently in use, is designed for voltages below 1.5 volts to save energy.
lithium batteries deliver 3.0 volts and lithium batteries even nominally 3.6 volts to a maximum of 4.2 volts.
the object of the present invention is therefore to reduce the size of a hearing device having a transmitting device and a power supply with voltage regulation.
this object is achieved by a hearing device with a transmitting device including an antenna for wireless, electromagnetic transmission of data, and a switching regulator including an inductor, which serves for the power supply of the hearing device and the transmitting device, wherein the inductance of the switching regulator with the antenna of the transmitting device is identical.
the inductance may comprise a partially open ring core. Due to the fact that the toroidal core is not completely closed, the magnetic flux is not completely guided in the toroidal core and can be used for electromagnetic data transmission.
an alternative embodiment is that the inductance in a cross-section 8-shaped, on one or has two sides open core.
the one or more openings serve to selectively effect electromagnetic emissions in order to realize a data transmission.
pulse width modulation pulse density modulation or amplitude modulation is used in the switching regulator for energy transmission.
modulation are characterized by the fact that they, as mentioned above, hardly affect the fundamental frequency and the fundamental phase of the signal of the switching regulator.
a further advantageous embodiment is that an additional inductance with a closed core is connected to the inductance switchable.
the additional inductance of the magnetic circuit is thus closed in the core, so that electromagnetic emissions are avoided as much as possible.
the hearing device here a hearing aid, an input transducer, in this case a microphone 10.
the microphone signal is fed to a signal processing unit 11, which in turn transmits an output signal to a receiver or loudspeaker 12.
the signal processing device 11 has a battery 13 with a downstream switching regulator 14.
the switching regulator 14 transforms the voltage supplied by the battery 13 to the desired operating voltage. If, for example, a lithium battery with 3 volts is used, the voltage is reduced below 1.5 volts, for example, with the aid of the switching regulator 14.
a rechargeable battery such as a lithium battery with nominally about 3.8 volts.
the voltage regulator 14 then regulates the battery voltage from 3.8 volts to, for example, 1.2 volts operating voltage.
the switching regulator 14 is an inductive switching regulator which has an inductance 15 for regulating the voltage.
the inductance is used to smooth the output voltage during switching operations.
FIG. 2 Furthermore, the hearing of FIG. 2 via a transmitter 16, which uses the inductance 15 as an antenna.
the inductance 15 is thus both part of the switching regulator 14 and the transmitter 16, which in FIG. 2 is indicated by the dashed line.
the inductor 15 thus has dual functionality.
the transmitter 16 is supplied as the signal processing unit 11 via the switching regulator 14 with energy.
the data to be transmitted is received by the transmitter 16 from the signal processing unit 11.
a single inductor 15 is used simultaneously for the switching regulator 14 and the transmitter 16, whereby a total of an inductance, which is known to require a lot of space, can be saved. So that the inductance can also be used as a transmitter or transmitting antenna, it must be able to radiate at least part of the magnetic energy. This can be achieved for example by an inductor z. B. does not have a closed ring core, but has a more or less large air gap in the ring.
FIG. 3 A first exemplary embodiment of such an inductor used according to the invention is shown in FIG FIG. 3 reproduced in plan view.
the inductor 15 here has a ring core 17 with a small gap 18.
the end faces 19, 20 of the gap 18 face each other, so that the magnetic field lines only slightly out of the gap. Consequently, only a weakly radiating antenna can be realized with this toroidal geometry.
FIG. 4 An example of this is in FIG. 4 shown. Again, it is an inductance 15 with a ring core 17.
the ring core 17 here has a large gap 21, wherein the end faces 22, 23 of the open ring core 17 are not directed towards each other. This geometry results in a completely different emission characteristic than in the example of FIG. 3 , In particular, the magnetic field lines extend far out of the gap 21, resulting in a stronger radiation.
any inductance whose core does not form a closed magnetic circuit If the core is closed, as mentioned, only a negligible proportion of the magnetic flux is conducted outside the core, which is unsuitable for an electromagnetic transmitter.
the geometry of the core of the inductance 15 is therefore to be optimized with regard to the emission characteristic, wherein a compromise is to be found with respect to as little energy loss as possible for the function of the switching regulator. For example, a linear dipole would be optimal for the transmitter, but unsuitable for the switching regulator, because it radiates almost all of the energy.
FIG. 5 A third embodiment of an inductor for common use for a switching regulator 14 and a transmitter 16 is shown in FIG FIG. 5 shown.
the core 24 has here in cross-section substantially the shape of an "8".
a winding 26 is wound.
the central web 25 is closed, while the two outer webs 27 and 28 each have a gap 29 and 30, respectively. These two gaps 29, 30 again provide the desired electromagnetic radiation.
the design of the inductor 15 is particularly suitable for SMD components, since they can be realized so very flat.
the pulse width modulation of the switching regulator can be realized independently of the modulations of the data transmission by means of conventional circuits.
a changing load of the switching regulator 14 would of course change the transmission energy due to the common use of the inductance 15.
the transmit power can be tuned to a system and its expected load by matching the radiated power and the shorted power by the geometry of the antenna or inductor, respectively.
