Definitions
- the present invention relates to a device for transmission and receiving data for remote controls of hearing aids with a transmitting device which has a transmitting coil, for sending data and a receiving device, the one Receiving coil for receiving data.
- Such a device is from the document DE 201 14 461 known. It serves as a sending and / or receiving unit for a hearing aid for wireless data transmission between the hearing aid and at least one external device.
- a sending and / or receiving unit for a hearing aid for wireless data transmission between the hearing aid and at least one external device.
- several transmitting and / or receiving coils are different Aligned spatial directions.
- Transponder antenna devices are known in which several Coils are used that are magnetically closely coupled are. Two or more coils are attached to one common core are arranged for data transmission used.
- Coils are preferably used for the long-wave range because is mainly transmitted inductively in the long-wave range. Sufficiently strong fields must be used for inductive transmission be generated.
- Coils with are particularly possible for the receiving circuit many turns necessary to get as much tension out to produce relatively weak fields. Such coils but are used as transmitter coils to generate strong fields low supply voltages particularly unsuitable. This problem occurs particularly with radio connections between two devices on when relatively low frequencies in Range of preferably 50 to 500 kHz can be used.
- Radio remote control For sufficiently long ranges of radio remote controls Correspondingly strong transmission fields are necessary. Should the radio remote control will also be designed to receive data another coil or winding for the Reception needed. Such a receiving coil is from heavily overdriven the field of the transmitter coil. This structure can lead to destruction of the receiver input stage without protection.
- the object of the present invention is therefore with limited supply voltage available a device for sending and receiving data for remote controls of hearing aids to propose the transmission power is sufficiently high.
- this object is achieved by a device for sending and receiving data for remote controls of hearing aids with a transmitting device that has a transmitting coil has, for sending data and a receiving device, which has a receiving coil for receiving Data, the transmitter coil and the receiver coil have a common one Own core so that the receiving coil for sending is excitable by the transmitter coil.
- the receiving coils generally have significantly higher numbers of turns than the transmitter coils can have without additional technical effort generated very strong broadcast fields are available, although only very low operating voltages stand. Therefore, no additional voltage multiplier needed, or batteries with less voltage is used, or less Batteries can be connected in series. This can also be done Save space or installation space.
- transmitter and receiver coil on one core is ultimately cheaper to manufacture than two completely separate ones Do the washing up.
- the receiving device can have a receiver, from which the receiving coil is separated by a protective circuit becomes. This should be done to the recipient protect excessive voltages caused by the transformer action can come from the transmitting and receiving coil.
- the protective circuit preferably consists of a capacitor and a parallel connection connected in series two anti-parallel diodes. This prevents the receiver, at whose input the diode parallel connection voltage is too high.
- the receiving and transmitting devices are preferably for designed for a frequency range from 50 to 200 kHz. This Frequency range is approved for remote controls.
- the receiving device can have a receiving resonant circuit, wherein the receiving coil forms the voice coil.
- the receiving resonant circuit is thus used in particular as a transmission power amplifier used.
- the receiving device should have a correction capacitor Have correction of the natural frequency of the receiving resonant circuit. This allows the frequency changes that caused by the inductances of the transmitter coils, compensate.
- the protective capacitor is favorably from the protective circuit simultaneously as a correction capacitor used, so that another component can be saved can.
- the transmitter is 1 equipped with one or more transmitter coils 2.
- the Transmitting coils are via a common core 3 with a receiving coil 4 coupled.
- a Resonant circuit capacitor 5 In parallel to the receiving coil is a Resonant circuit capacitor 5 connected.
- the diodes 7 and 8 connected in parallel are connected to the input of a receiver 9.
- the mode of operation of this circuit is described in more detail below explained.
- the separate receiving coil 4, which is necessary anyway is wound on the same core on which the Transmitter coils 2 are located.
- the receiving coil 4 the with its associated capacitor 5 a complete resonant circuit represents through the transmitter coils 2 also to Swing excited. Since the receiving coil 4 compared to the transmitter coils has 2 more turns, are in the receiving resonant circuit 4, 5 relatively high during the transmission process Tensions generated by the vibration effect of the Resonant circuit despite the many turns right again generate high currents. Deliver the actual transmitter coils 2 now only the radiated energy. Therefore needs not so much current to flow through these coils. The strong transmission field is now affected by the transmission coils 2 excited receiving coil 4 generated.
- the frequency is absolutely stable and can be specified from the outside. tolerances the components in the resonant circuits have no influence to the transmission frequency. They only act in a certain way Measure of the efficiency of the transmitter 1.
- the inductances of the transmitter coils 2 change the Inductance of the coupled receiving coil 4, so that the natural frequency of the resonant circuit 4, 5 after changing the associated Capacitance value of the resonant circuit capacitor 5 corrected must become.
- the inductance of the resonant circuit is smaller, i.e. the capacity of the resonant circuit must be increased become. A suitable capacity can do so without problems can be connected in such a way that they also protect the sensitive receiver input level 9 is used. Because one Protection circuit 6, 7, 8 would have been needed anyway this circuit solution without additional components.
- the Protection circuit 6, 7, 8 consists only of the correction capacitor 6 and two diodes 7 and 8 connected in anti-parallel, the parallel to the capacitor 5 of the receiver resonant circuit are connected.
- the receive signals are on the diodes 7, 8 tapped.
- Voltages of typically around 50 volts go through the diodes 7, 8 in the conductive state and thus switch them upstream capacitor 6 parallel to the resonant circuit capacitor 5 of the reception group. So that the resonance frequency of the resonant circuit 4, 5 corrected for transmission.
- the signals at the input of the high-impedance Receiver limited by the diodes 7, 8 to a maximum of about 0.7 volts. Most of the voltage generated by the resonant circuit drops then on the protective capacitor 6.
- reception signals are so small that block the diodes 7, 8.
- the voltages of the received signals typically reach at most the mV range. Thereby only the original resonant circuit capacitor 5 is still active.
- the transmitter coils 2 are switched off. The That is, at least one connection of each transmitter coil 2 is open. So that they do not affect the receiving resonant circuit 4, 5 more out. So it can on its reception frequency, on the he is tuned to swing freely.
- the signal is almost without losses through the protection or correction capacitor 6 transmitted to the protective diodes 7, 8 further. Because of the low reception voltage, these diodes 7, 8 blocked. That the receive voltage can be at the diode connections completely removed from the high-resistance receiver input become.
- reception coil is used as a transmission amplifier
- the protective capacitor also serves as a correction capacitor
