Definitions

  • the invention relates to a portable on or in the ear headset with hearing aid functionality.
  • headsets for communication devices and in particular for mobile phones which is one of electrical or electromagnetic output to the communication device Convert signal into an acoustic signal and into the ear of the headset wearer.
  • Headsets consist essentially of two handsets that are on the two ears of the headset wearer and the over a headband are connected together.
  • a corresponding headset is fixed in or on the ear.
  • Such a headset consists of two parts, one worn in front of the ear Part and a behind the ear grabbing holding part for fixing.
  • Headsets also have a microphone in addition to the handset receives a voice signal output from the headset carrier and converts it into an electrical signal. The electrical signal is then - if necessary after further processing - forwarded to the communication device.
  • the connection of the Headsets with the communication device can be wireless or be executed wired.
  • the headset includes an amplifier with adjustable gain.
  • a microphone may be present on the headset be, which absorbs the ambient sound. The ambient sound is converted into an electrical signal, amplified, again converted back into an acoustic signal and supplied to the hearing of the headset wearer. This can do that Headset can be used as a hearing aid.
  • the amplifier is adjusted so that a hearing loss of the headset wearer at least largely compensated.
  • pocket hearing aids are known from the prior art, the one from the actual pocket device and one with it connected listeners. To fix the receiver in the ear becomes one according to the individual circumstances of the hearing aid wearer manufactured earmold used.
  • the earmould includes an annular holding part, preferably made of metal, in a correspondingly shaped shape of the listener according to Art a snap fastener connection can be snapped.
  • a Otoplasty intended for this special purpose is also called "SE-Mulde" (Secret-Ear Mulde).
  • an amplifier and a listener in which an acoustic signal through the microphone recorded and converted into an electrical signal is that then amplified, in an audible signal converted back and over the handset in the ear canal of the headset wearer is delivered, so in a headset with hearing aid functionality, occur in terms of feedback the Same problems as hearing aids. These will be particular caused by the fact that the microphone and the handset have a relatively small distance from each other.
  • Object of the present invention is therefore, in a Headset with hearing aid functionality to avoid feedback.
  • a portable on or in the ear Headset with hearing aid functionality comprising a headset module and an ear piece detachably connected to the headset module.
  • a headset according to the invention comprises at least two detachable interconnected modules: a headset module and a Earpiece.
  • the headset module includes the electronics of the Headsets, in particular a transmitting and receiving unit for data transmission between the headset and the communication device, a microphone and an amplifier.
  • the headset is detachable with an earpiece connected, which preferably rests against the concha of the ear and partially protrudes into the ear canal.
  • the ear piece may only be on the concha or only on the ear canal issue.
  • Headset module and ear piece Due to the detachable connection of the two essential headset components (Headset module and ear piece) can be added to any headset module a variety of ear pieces provided which makes for each headset wearer a suitable earpiece can be selected, which depends on the required Reinforcement especially in hearing aid operation Ear canal seals in a suitable manner. Feedback occur namely, especially if that of the microphone received signal experiences a high gain before it Ear of the headset wearer is supplied. A high feedback tendency is thereby countered by the invention, that in a simple and fast way the ear canal especially good sealing ear piece can be chosen so that the feedback path from the listener to the microphone is interrupted becomes.
  • the ear piece designed as a universally fitting ear piece.
  • Universal matching ear pieces can, in particular, with small gain and associated low feedback tilt be used. Nevertheless, the best possible seal to reach the auditory canal are preferably different universally fitting ear pieces, e.g. for close, middle and wide auditory canals offered.
  • the ear piece is preferably as adapted to the ear canal of the headset wearer, individually molded earmold executed.
  • the earmold is based on an ear impression of the headset wearer individually shaped and with connection means for detachable connection with provided the headset module.
  • the connecting means preferably form a snap closure or a bayonet closure.
  • the am Ear-mounted headset can thus easily in the right one Direction to be rotated, without causing the seal of the ear canal deteriorates.
  • Preferred embodiments of the invention with rotatable together attached modules see stop means or detent positions before, the rotation to a certain angle range restrict or where the alignment of the two Parts locked relative to each other in certain locking positions.
  • a further embodiment of the invention provides that between the headset module and the earpiece an adapter piece is provided. This is with the headset module or the Earpiece, but preferably releasably connected to both.
  • the adapter piece has the advantage that the ear piece at worn headset further into the ear canal and protrudes in addition to a standard connection (e.g. a SE-well) another, to the special circumstances and component dimensions adapted, releasable connection selected can be. Furthermore, by the adapter piece as well the possibility of connection with different ear pieces created by a specific manufacturer.
  • Fig. 1 shows a schematic, highly simplified representation a headset with a headset module 1 and a detachable with this connected earpiece 2A.
  • the headset module 1 comprises a transmitting and receiving unit 3, the wireless Data transmission between the headset and a communication device is connected to an antenna 4.
  • a signal processing unit 5 available for further processing and amplification of the received signals.
  • the reinforcement takes place preferably as a function of the frequency of the to be transmitted Signals to compensate for a hearing loss of the headset wearer.
  • the processed signals are finally in one Handset 9 turned into acoustic signals and over a Sound channel 7, which passes through the ear piece 2A, in the ear canal submitted the headset wearer.
  • the headset module 1 comprises a microphone 8, through which one of the headset wearer Outgoing acoustic signal in an electrical Signal converted and via the transmitting and receiving unit. 3 and transmit the antenna 4 wirelessly to a communication device becomes.
  • the headset according to FIG. 1 can also be used as a hearing aid become.
  • a received from the microphone 8 and signal converted into an electrical signal is further processed and in particular depending on the signal frequency amplified to compensate for a hearing loss of the headset wearer.
  • the amplified signal is via the handset 6 in the Auditory canal of the headset wearer delivered. Since the handset 6 and the microphone 8 are relatively close together a high feedback tendency. This will be beneficial prevented according to the invention in that the mouth of the Sound channel 7A acoustically opposite the microphone opening 8A is sealed. According to the invention this is done by an ear piece 2A reaches, the ear canal entrance as close as possible closes.
  • a closure 9 is provided which is a quick and easy to be solved connection between the headset module 1 and the Ear piece 2A creates. So it is possible that a variety of Ear pieces can be provided, wherein for the individual Headset wearer by trying a suitable earpiece is selected. Preferably, different ear pieces offered for small, medium and large auditory canal diameter.
