Definitions

  • the present invention relates to a hearing aid having a housing, a signal processing device accommodated in the housing, and an LED, which is arranged on the housing and which serves to represent a state of the signal processing device or an electronic component.
  • 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 device.
  • some hearing aids are equipped with an LED for status display (eg hearing aid on / off, program number, battery status).
  • an LED for status display eg hearing aid on / off, program number, battery status.
  • a hearing aid which outputs a signal when falling below the state of charge of a voltage source.
  • the publication WO 2004/110098 A1 indicates a hearing aid which outputs a signal to an LED for monitoring the battery voltage.
  • the US 2002/0159613 A1 teaches to issue a low battery voltage warning only for a short period of time to save the battery.
  • the monitoring unit By arranging the LED between a positive terminal of the battery and the first terminal, which is in communication with the monitoring unit, it is advantageously possible to still bring the LED to light, although the monitoring unit in its capacity as a "power management" due to low battery voltage, the signal processing device has already switched off. Due to the low battery voltage, the hearing aid can no longer work properly, but the remaining battery voltage can be used by the intended wiring of the LED to the safe statement for a no longer sufficient battery voltage.
  • the monitoring unit is designed to switch off the signal processing device when it falls below the first voltage limit with respect to the audio functionality. In order to ensure a secure audio functionality, which is provided by means of the signal processing device, it is safer to turn it off completely after a certain voltage, since signals can no longer be transmitted without interference.
  • the switching element is connected to a fourth input of the signal processing device, and the monitoring unit is designed to detect an actuation of the switching element at a battery voltage below the first voltage limit.
  • This design of the hearing aid it is possible to detect a switch-on attempt at insufficient battery capacity and display the LED. This solves the problem known in prior art hearing aids that when LEDs are present to indicate too low a battery status, they begin to shine from the time the battery voltage is insufficient. However, this procedure, which is known from the prior art, allows the operating voltage of the battery to drop further during the entire operating time of the LED. Imagine, the user puts his hearing aid off overnight, the battery of the hearing aid is already close to reaching an insufficient voltage.
  • the LED status indicator would start to light up in order to signal a low battery status, the LED would light up for the entire duration of the hearing aid not being used, and the battery would probably be completely exhausted and the hearing aid can no longer receive any status signals be removed, but the fact that the LED in the hearing aid according to the invention only lit when a switch-on was made, the battery was spared so far that even the next morning can be diagnosed sure that the battery is empty.
  • the monitoring unit is designed with a time counter for switching the first terminal for a determinable period of time. It would be possible, for example, after a switch-on at too low a battery voltage, the LED light up for two seconds to then turn them back to dark.
  • the object mentioned at the outset is likewise achieved by a method for operating the abovementioned hearing device, wherein the signal processing device is switched off when the battery voltage required for safe operation falls below a threshold and, in the case of a switch-on attempt via the switching element, the LED by means of the monitoring unit with the battery connected, that the remaining battery voltage is used to bring the LED to light up.
  • the signal processing device is switched off when the battery voltage required for safe operation falls below a threshold and, in the case of a switch-on attempt via the switching element, the LED by means of the monitoring unit with the battery connected, that the remaining battery voltage is used to bring the LED to light up.
  • this method it is in principle possible to permanently light the LED with the remaining battery voltage, but this has the disadvantage that this permanent energy consumption empties the battery so far that a reliable diagnosis, whether the battery is empty or another Error of the hearing aid is the hearing aid can not be removed.
  • the LED is lit from a start time of the switch-on attempt for a determinable period of time on the first port and turned off after the period of inactivity.
  • the LED is driven to signal a battery change with a pulse train is, the pulse train corresponds to a maintenance code.
  • the pulse train corresponds to a maintenance code.
  • FIG. 1 exemplifies an HDO hearing aid with a housing 11 again.
  • the housing 11 conventionally includes one or more microphones 12, a signal processor 13, a receiver 14, and a battery 15.
  • An LED 16 connected to the signal processor 13 serves to signal a low battery voltage U.
  • the hearing aid can be turned on.
  • the switching element 17 is connected to the signal processing device 13, wherein the signal processing device 13 is configured to recognize a key on the switching element 17 and turn on the hearing aid.
  • the signal processing device is supplied via the battery 15 and noises are received via the microphone 12, supplied to the signal processing device 13 and amplified via a receiver 14.
  • FIG. 2 a circuit arrangement is sketched, which makes it possible for the hearing aid to bring the LED despite a shutdown of the signal processing device 13 to light up.
  • the signal processing device 13 is switched on properly after a switch-on attempt via the push-button 17 and the hearing aid starts operating with the battery voltage U of 1.2 V.
  • the signal processing device 13 is connected to the positive pole of the battery 15 via a first supply voltage line 28 and to the negative pole of the battery 15 via a second supply voltage line 29.
  • the LED 16 is connected with its anode side to the positive terminal of the battery 15.
  • the cathode terminal of the LED 16 is connected to a first terminal 21 of the signal processing device 13.
  • a monitoring unit 25 is configured in such a way that, preferably configured in semiconductor technology, it has switching means which connect the first terminal 21 to the second supply voltage line 29 by means of a corresponding circuit design of the signal processing device 13 or the monitoring means 25 in such a way that a current flows from the positive pole of the Battery 15 can flow through the LED 16 to the negative pole of the battery 15.
  • This circuit function of the signal processing device 13 or of the monitoring device 25 implemented, for example, in a freely programmable circuit should preferably be possible if the monitoring device 25 determines that the battery voltage 15 has dropped below a value of 0.9 V, for example.
  • the signal processing device 13 still operates properly up to a value of 0.9 V and thus secure audio functionality is ensured. If the voltage falls below 0.9 V, a "power management functionality" implemented in the monitoring means 25 is carried out. That is, the signal processing device 13 is turned off with respect to its audio functionality, and in the monitoring means, at the same time, the current path through the LED 16 is prepared. A voltage of 0.9 V is still sufficient to drive a current through the LED 16 and thus bring them to light up.
  • the signal processing device 13 is designed, again as a programmable integrated circuit, to recognize a switch-on attempt via the button. While This switch-on attempt, the LED 16 is connected by means of the monitoring unit 25 with the battery 15 so that the remaining battery voltage U brings the LED 16 to light.
  • the monitoring means 25 has a time counter 26, which brings the LED 16 from a start time of the switch-on attempt for a determinable period of time via the first terminal 21 to light and after the period of time, the LED 16 is switched inactive.
  • the signal processing device 13 has an LED driver 27.
  • This LED driver 27 is configured to provide enough power to bring even at this low battery voltage U, the light emitting diode 16 to light up.
