Definitions

  • the present invention relates to a hearing aid with a Power supply device for supplying a the hearing aid device connectable external device.
  • the present invention relates to a corresponding Method for operating the connected to the hearing aid external device.
  • Hearing aids worn behind the ear have in In most cases an audio input which serves external Signal sources to connect.
  • External signal sources For example, so-called CROS microphones (contraradial routing of signals), audio equipment, FM transmission systems etc. Some of these connected devices require one from Hearing aid supplied supply voltage. Need of it For example, the CROS microphones an extremely stable supply voltage at relatively low power consumption. For three microphones of a hearing aid is thus a Power consumption up to about 300 ⁇ A.
  • Such a regulated Voltage supply in this current range can be by usual Voltage regulator can be ensured.
  • Hearing aids have traditionally been used in the past regulated supply voltage at the audio input, because mainly CROS microphones with low power consumption too to supply. As later small miniature FM systems on came the market, the hearing aids had to do this accordingly to be converted. Modern hearing aids are therefore already with unregulated power supply at the audio input Mistake. Therefore, in the case of a CROS supply, special Microphone devices with internal voltage stabilization needed.
  • From DE 37 05 478 A1 is an electronic hearing device known with four connections, of which the first connection with a first signal source, e.g. a wireless, a recorder, a radio, a television or a warning device, connected is.
  • the second connection is with a microphone and the third port is connected to a computer.
  • the fourth connection and possibly other connections are for Connecting additional signal sources provided.
  • T2 From DE 690 31 277 T2 is a hearing aid with a circuit Known on the external components, such as an on-off switch and a contact point, are connected.
  • the contact point is via a circuit connection with a Voltage source connected to the circuits in the circuit supplied with different regulated voltages.
  • From DE 102 11 364 A1 is a device for switching off of signal processing devices of a hearing aid known. This device has a watchdog logic for turning on and off a hearing aid signal source.
  • the disadvantage here is that on the one hand an additional Audio contact is needed, so the audio input is typically has the following four contacts: signal contact, Ground contact and two power supply contacts.
  • Another disadvantage when providing both supply voltages need to be, is that for every application a separate audio shoe provided must be, which serves, either the regulated or the unregulated operating voltage for the connected Device to provide.
  • the object of the present invention is therefore to the power supply for connectable to hearing aids make external devices more comfortable.
  • this object is achieved by a hearing aid with a power supply for supply a connectable to the hearing aid external device, a load detection device for detecting the electrical load connecting the external device to the power supply forms, and a control device for controlling the power supply device available voltage depending on the detected electrical Load.
  • the invention provides a method for Operating an external device connected to a hearing aid Device by supplying the external device with a electrical voltage from the hearing aid, detecting the electrical load affecting the external device at the Hearing aid forms, and controlling the electrical voltage depending on the detected electrical load.
  • Automatic load detection always makes the right choice Supply voltage provided at the audio input. Thereby eliminates all retooling work on the hearing aids. Elaborate CROS devices with built-in screen circuits will be also not needed anymore. In addition, customer inquiries are omitted because of device compatibility issues and the value of Products as well as customer satisfaction increase.
  • the power supply device has a regulated voltage source and an unregulated voltage source. This makes it possible, for example, with external devices low power consumption automatically with regulated voltage and devices with high power consumption with unregulated voltage to supply.
  • the automatic switching takes place between the regulated and unregulated voltage source the detected load forming the external device.
  • the load detection device may be a current measuring circuit and a comparator for comparing a measured current with a switching threshold.
  • Advantageous to the Current measurement is that not only a load but also a Short circuit case can be detected.
  • the load detection device may include a voltage monitoring circuit and a comparator for comparison a determined voltage with a switching threshold include.
  • the voltage monitor has the advantage that it can be relatively easily realized.
  • Hearing aid has a microphone as input components 1 and a telecoil 2. Deliver both components their signals to a preamplifier 3, with an A / D converter and a voltage regulator.
  • the preamplifier 3 feeds its output signal into a digital one Signal processing unit 4 with clocked output stage.
  • the output signal of this digital signal processing unit is supplied to a receiver or loudspeaker 5.
  • Both the preamplifier 3 and the digital signal processing unit 4 are using a battery 6 with voltage provided. Furthermore, a volume control 7, which is connected to the digital signal processing unit 4 is to adjust the volume on the handset 5. Further is the digital signal processing unit 4 via a MTO switch 8 in the microphone mode, the telecoil operation or the off state switchable. With a programming socket 9, the digital signal processing unit 4 program in a suitable way. Finally, through a Situation key 10 the operation of the digital signal processing unit 4 further specified. That's the way it is For example, possible from the pure telecoil operation in a mixed operation with consideration of microphone signals to switch. Furthermore, the microphone operation can be specified thereby be that with the situation key 10 one or more Microphones used to generate the output signal become.
  • the preamplifier 3 has an additional audio input 11, via which an audio signal from an external device, such as a CROS microphone and / or a Miniature FM receiver, which takes into account hearing aid can be.
  • the audio input 11 has an audio voltage supply contact, that of a load detection device 12 is fed.
  • This load detection device 12 is a supply voltage switching unit with either the voltage of the voltage regulator of the preamplifier 3 or the looped by the amplifier 3 battery voltage of Battery 6 can be switched to the audio input 11.
  • Load detection measures the load detection device 12 the Power entering the device connected to the audio input 11 (not shown) from the supply voltage source. 3 or 6 is flowing. If the measured current is high, then the switching unit, the battery voltage to supply the selected external device. Otherwise, the voltage regulator is used as a voltage source.
  • Comparator can be the current measurement signal with a threshold be compared. If the current measurement signal is above the Threshold, this indicates a load with high power consumption whereas the falling below the threshold value pointing to a load with low power consumption.
  • the current sense signal becomes additionally compared over a second threshold, which is above the first threshold.
  • This second one Threshold is used to short-circuit the connected External device to determine.
