Definitions
- the invention relates to a hearing aid with an electronic amplifier, a microphone is connected to the input and a loudspeaker is connected to the output.
- Hearing aids have been developed for people with hearing impairment or reduced hearing, in which the acoustic signal is converted into an electrical signal and this is divided into different frequency channels by means of bandpasses.
- the signal in question is individually amplified with the aid of a dynamic compressor, depending on the person's hearing, after which the amplified signals are combined and fed to the loudspeaker, which emits an acoustic signal that is optimal for the person.
- the state of the art nowadays includes mobile telephones which would also like to be used by the persons mentioned above. This leads to some inconvenience for such people; z. B. the frequency responses of the frequency channels can be set such that the acoustic call signal of the mobile phone is perceived poorly or not at all. If, for example, the mobile telephone is in a pocket, file folder or the like which dampens the call signal or in an adjoining room, the case may occur that the person does not perceive the call signal at all despite the hearing aid. Furthermore, feedback can occur between the electroacoustic transducers of the mobile phone and the hearing aid.
- the call signal activates a built-in vibrator, the vibrations of which signal a call to the person, and protective circuits against feedback, but these measures cannot completely rule out interference of the type mentioned. If e.g. B. the mobile phone is not worn on the body, the vibrator is ineffective as a signal generator.
- the aim of the invention is, on the one hand, to eliminate the disadvantages mentioned and, on the other hand, to create a device which provides hearing-impaired people with an optimal level of safety and convenience.
- This aim is achieved according to the invention with a hearing aid of the type specified at the outset by a receiver which is tuned to a predetermined radio signal corresponding to a telephone number and is connected to an acoustic signal transmitter which, when the receiver responds to the radio signal, is controlled to emit an acoustic signal is.
- the invention provides a hearing aid in which the call signal is fed into the hearing aid via the receiver and thus the wearer of the hearing aid receives the call signal in the hearing aid itself, regardless of the location of his cellphone or whether the cellphone is on or off is switched off.
- the receiver can be connected to the input of the amplifier and serve as an acoustic signal generator for the loudspeakers of the hearing aid. This synergy can significantly reduce the number of components required in the hearing aid.
- the amplifier is of the type in which it has, in a manner known per se, at least two dynamic frequency compressors associated with different frequency bands with a summing element connected downstream.
- the receiver can be designed to be adjustable to the predetermined radio signal, so that it can be easily adjusted to this, for example when the telephone number changes.
- a matching element can preferably be connected between the receiver and the amplifier in order to optimally adapt the receiver to the amplifier.
- the receiver is preferably also designed so that it can be switched off so that the hearing device does not respond to telephone calls. This is e.g. This is advantageous, for example, if the user uses the hearing aid while sleeping, but does not want to be disturbed by telephone calls.
- Fig. 1 shows this embodiment of the invention.
- a hearing aid 1 has a microphone 2, which is connected to the input of an amplifier 3, to the output of which a loudspeaker 4 is connected.
- the amplifier 3 preferably has three bandpasses on the input side, which are assigned to different frequency bands and each of which is followed by a dynamic compressor in order to amplify the signals of the frequency bands differently depending on the hearing ability of the wearer of the hearing device 1.
- the outputs of the dynamic compressors are connected to a summing element in which these signals are combined and fed to the loudspeaker 4.
- Such hearing aids belong to the prior art.
- a receiver 5 is structurally combined, which on a predetermined, a telephone number, u. between that of the mobile phone used by the wearer of the hearing device 1, the corresponding radio signal responds or is coordinated.
- An adjusting element 6 is provided for tuning to this radio signal.
- the output of the receiver 5 is connected to the input of the amplifier 3 via an adapter 7.
- the cell phone If the cell phone is selected, not only does it respond to the radio signal, but also the receiver 5, which emits an output signal to the amplifier 3, which in turn emits a signal to the loudspeaker 4, which emits an acoustic signal and thus indicates to the wearer of the hearing aid 1 that the mobile phone is being called.
- the wearer of the hearing aid 1 is thus informed of a call to his mobile phone, regardless of where the mobile phone is located, even when the mobile phone is switched off.
- the receiver 5 can be provided with its own amplifier, to which a separate acoustic signal generator or the loudspeaker 4 is connected.
- the receiver 5 is expediently designed such that it can be switched off, or the connection between the receiver 5 and the amplifier 3 can be interrupted, so that the user has the possibility of being spared unwanted telephone calls.
