1 Claim. (01. 179-107) The invention relates to a microphone relay armature is held between the screws 34 and 35, hearing apparatus, as described in the present one from each side, having the insulating heads specification and illustrated in the accompanying 36 and 37 and this vibration is limited by the drawing that forms part of the same. head 38 of the armature operating within the The invention consists essentially in establishslots 39 in the body pieces 27 and 28. no
ing a magnetic field from which a vibrating an The dental contact 40 projects from the head mature projects as a dental contact, cooperating 38 and preferably terminates in a ball end, the with an amplifier and a source of electric curprojecting portion of the contact extending rent, as pointed out in the claim for novelty through the orifice 42 at the end of the case 20,
' following a description in detail of the contact thus at one end of the vibrating device, the con- 05 member with general reference to the connectact extends outwardly while at the other end, tions. the grip forms the means of handling the vibrator.
The objects of the invention are to enable the It will thus be seen that there is a magnet deaf to hear with distinctness not usually atfield established within the case, and that this tainable with what are known as earphones, and can be operated in contact with the teeth of the 70 thereby eliminate many of the diiliculties incident deaf person, so that this person plainly hears any to social and business intercourse by those suifersound amplified sufiiciently to be recognized. ing from this great affliction; to furnish a portable The cable 23 extends to the amplifier 45, which equipment for each person requiring the apparais of conventional construction and contains a tus, whereby it can be brought into instant use battery forelectrifying the magnetic field and for 75 and insure perfect service in this direction for use in the amplifier, and connected to this amany and all persons suffering from a weakness plifier by the wire 43 is a microphone 44 through in so far as their hearing is concerned, and genwhich the person speaks to the deaf person, and erally to provide a convenience to deaf people by this sound is amplified and by means of the mag- 5 a new system of telephone communication, not netic vibrating contact, the sound reaches the so heretofore available to the deaf. ears of the deaf person.
