Definitions

  • the invention relates to enabling telephony for users wearing a hearing aid.
  • a solution to overcome this problem has been to include means for converting the signal normally output through a loudspeaker of the telephone to to a magnetic field in the telephone. By doing so, the signal quality and therefore also e.g. understandability of speech improves considerably, since the hearing aid does not amplify acoustic environmental noise in so-called T-coil mode. Since the size of the target user group for such devices is rather limited, manufacturing telephones in long series as stipulated by the production line efficiency would be impossible. If the same feature were included in a mainstream telephone, the manufacturing cost would be higher thus reducing the manufcaturer' s profit.
  • a prior art solution to overcome this problem is to use inductive loop as an accessory that is connected to the phone through a connector at the bottom of the telephone.
  • An example of this kind of accessory is "Nokia Mobile Inductive Loopset LPSl".
  • LPSl Nokia Mobile Inductive Loopset LPSl
  • An objective of the invention is to improve the comfort of using telephony services when wearing a hearing aid device. This objective can be achieved as set out in independent patent claims 1 or 11.
  • Another objective of the invention is to improve the suitability of a telephone for various user groups, while not substantially increasing manufacturing costs. This objective can be achieved as set out in independent patent claim 5.
  • a cover suitable for a telephone comprises means for receiving a signal; and means for converting the signal to a magnetic field, the magnetic field being suitable for being received at a hearing aid, the user of the telephone does not need to use an "Inductive Loopset" -like solution.
  • cover is exchangeable, same telephone can be addressed to different user groups, whereas different user groups may prefer using different kinds of covers for their telephones.
  • the means for receiving a signal comprises a spring elastic contact member on a support plate connected to the cover, the support plate further providing an electrical connection to the means for converting the signal to a magnetic field, the design of the cover be more creative since there is no need any more for a fixed contact point at a boundary of the cover.
  • a cover can be used with the telephone.
  • a magnetic field e.g. a T-coil
  • every telephone of the same type would involve higher manufacturing cost. In most cases this would be in vain, since the T-coil would finally be needed by a relatively small user group only.
  • users who need hearing aid will also benefit, because their telephones too can be manufactured in long production series, thus pressing down the manufacturing costs .
  • a telephone further comprises means for passing a speech or alert signal to an acoustic transducer; and if the telephone is adapted not to pass the speech or alert signal to the acoustic transducer when the speech or alert signal is passed to the cover, the telephone will not disturb a user using a hearing aid by passing same signal first to the loudspeaker and then to the magnetic induction loop.
  • a telephone further comprises detecting means for automatically detecting the presence of the cover or of the means for converting the signal to a magnetic field; and means responsive to the detecting means, adapted to: i) automatically change the telephone to pass the electric signal to the cover when the cover is present; and/or ii) automatically change the telephone to pass the electric signal to the acoustic transducer when the cover is not present, the user does not necessarily need to manually change settings of his or her telephone when he or she inserts a cover according to an aspect of the invention.
  • a telephone furthermore comprises a cover according to an aspect of the invention, the telephone may then be used for telephony services.
  • the means in the cover for converting the signal to a magnetic field are at least 2 mm above a surface of a printed circuit board of the portable telephone, the reflections of the metal coating of the PCB can be reduced. Furthermore, if the telephone is dropped, together with its cover, the probability of the converting means colliding with the PCB can be reduced. Because the cover may at least partially consist of flexible material, the separation can protect the converting means when the cover is being bent.
  • the telephone is a portable telephone, especially a cellular phone or a DECT phone
  • the user of the telephone is not bound to limiting posed by a cable in that where he/he can use his/her telephone.

  • the processing unit 109 comprises means for controlling the operation of the telephone 100. Telephones are as such very well known, more detailed description can therefore be omitted.

  • Means 107 for passing a speech or alert signal S to a cover 200 can include a connector, a connection pin, or any other means suitable for passing the speech or alert signal S to a cover 200. They are preferably positioned within some cm from the acoustic transducer 105. The reason for the positioning is that the acoustic transducer 105 is, because of anatomical reasons, usually located very close to ear.
  • a hearing aid will also be located very close to ear, say, even inside the ear, hence making it favourable to place the converting means 103 close to the ear too, in order to avoid long wiring or other conducting of the signal S it is feasible to put the connection point close to the acoustic transducer 105.
  • the acoustic transducer 105 may be removable.
  • the means 107 for passing a speech or alert signal S to the cover are then preferably connectable to a socket on the PCB which originally was intended for the acoustic transducer 105.
  • Means 107 for passing a speech or alert signal S to a cover 200 receive the signal preferably from a processing unit 109.
  • the telephone 100 is an analogic telephone, such as those used for PSTN telephony, it is not necessary that the telephone 100 comprises a processing unit 109 but an amplifier or any other suitable component will do.

  • the converting means 203 generate a required magnetic field which is picked up by the hearing aid 400. Since only a fraction of all telephones need to support a hearing aid, it is an advantage from cost side to place e.g. a T-coil in a clip-on front cover. This is also a good solution from signal-to-noise point of view since the magnetic field is stronger when the distance from the converting means 203 to the hearing aid 400 is at shortest.
