Embodiment Construction

[0019] figure 1 A first preferred embodiment of an audio transmission device 1 according to the invention is shown. The audio transmission device 1 is entirely surrounded by a housing 2, the cover of which is not shown. The housing 2 is preferably palm-sized so that finding its mounting position presents the least possible problems. During assembly of the audio transmission device 1 the housing is connected to the elevator by bolts in the bolt holes 3 . The audio transmission device 1 is provided with electronics 4 which are preferably housed in a printed circuit board (PCB). The electronic device 4 comprises: a microphone 5 ; a mixing device 6 for mixing / superimposing a plurality of input audio signals to form one mixed audio signal; and an induction loop amplifier 7 for feeding the mixed audio signal to a loop antenna 8 . The loop antenna is arranged around the edge of the housing and on its inner side. The electronic device 4 is provided with a power supply connection 9...

Abstract

The invention relates to an audio transmission device intended for co-action with a hearing aid provided with a loop listener for application in a lift for the purpose of converting a first audio signal originating from one or more audio sources in the lift, including the lift communication system, to a magnetic field suitable for receiving on the hearing aid, comprising a power supply connection, a first audio input connection intended for the purpose of receiving the first audio signal, an induction loop amplifier intended for the purpose of amplifying the first audio signal and a loop antenna which is coupled to the induction loop amplifier and intended for the purpose of generating the magnetic field.

Description

technical field [0001] The present invention relates to an audio transmission device for use in an elevator, in cooperation with a hearing aid having a loop listener, for transferring first An audio signal is converted into a magnetic field suitable for hearing aid reception, the audio transmission device comprising a power connection, a first audio input connection for receiving the first audio signal, an induction loop amplifier for amplifying the first audio signal ( induction loop amplifier), and a loop antenna (loop antenna na) coupled with the induction loop amplifier and used to generate a magnetic field. Background technique [0002] There is a great need to make buildings more accessible to the hearing impaired. In the event of a disaster, eg in an elevator, it is desirable to accommodate this population. However, it is a known problem that hearing aids do not function optimally in small enclosed spaces such as in elevators. The audio transmission device accordin...
