Definitions

  • My invention refers to telephone receivers, and more especially to telephone receivers which. can be inserted in the auditory duct.
  • the above disadvantages are avoided by giving thetelephone a substantially L-shaped contour, the arm intended for the auditory duct containing the telephone diaphragm as well as the magnet coils, whilst the magnet is arranged in the other arm.
  • the distribution of weight is suitably arranged in such a manner that the centre of gravity of'the whole telephone is located in the part to be inserted in the auditory duct.
  • FIG. 1 is a section of wear and auditory duct showing the manner in which the telephone is fastended in the ear.
  • Fig. 2 is a back view of the apparatus with the closing cap removed.
  • Fig. 3 is a cross-section of the apparatus.
  • Fig. 4 is a front view of the apparatus with the ear piece and diaphragm removed.
  • Fig. 5 is a modification of a detail.
  • Fig. 6 is a longitudinal section through the middle portion of the telephone in larger scale.
  • Fig. 1 of the drawings illustrate the man-. nor in which the telephone is fixed in the ear.
  • the horizontal part which is provided with an oval or olive shaped ear piece, is inserted in the auditory duct proper; the vertical part to which the connections are attache'd, fits into the incisura intertragica and lies up against the lobe of the car.
  • the apparatus clings to the ear without further holding means and with such firmness that the possibility of the apparatus dropping out is remote even if a certain amount of tension be exerted on the attached conductin wires.
  • the telephone is containedin a casin of non-magnetic material, such as brass.
  • casing consists of a cylindrical chamber 1,
  • a U-shaped magnet 3 is provided in the prismatic chamber, whilst the pole shoes 4 bearing the magnet coils 5 are contained in the cylin- Extensions 7 of the pole shoes project through slots inthe back wall or partition 6 of the chamber 1 and into the back chamber where they touch against the sides of the upper ends of the U-shaped magnet 3.
  • Screws 8 which rigidly press the casing, the extensions 7 and the magnet against one another and keep these parts in their relative positions, are screwed through the casing from the outside.
  • a small block 9 f insulating material is arranged in the cham her 2, the said block being-provided with small screws 10 for connecting the interior wiring with the exterior wiring 11.
  • the wiring 11 is taken through a slotted bushing 12 which is compressed by means of a cap nut 13 in such a manner as to keep the wiring 11 rigidly in position.
  • the inner wiring extends from the chamber 2, the open back of which is closed by means of a cover 15 fastened by screws and reaches the cylindrical front part 1 through a boring 1 1.
  • a small iron disc 16 serving as the armature is arranged opposite the pole shoes 4, this disc being fastened to a dlaphragm of gold-beaters skin 17 or other membranous material suitable for this purpose.
  • the diaphragm is tautened by means of a cylindrical plug 18 inserted in a socket-like element 19 which is threaded onto chamber 1.
  • This socket is followed by an ear piece 20 of ebonite or some othersuitable material, which is inserted in the auditory duct.
  • a lock-nut 21 is screwed against .the end of 1 socket 19.
  • the releasing and readjusting of the screw arrangement offers a very handy means for adjusting the distance between the diaphragm and the pole shoes so as to provide the de ree of sensitiveness required for the individual cases.
  • an abutment 22 isprovided which revents the lock nut 21 from being screwed ack too far.
  • the olive shaped earpiece 20 is attached to the diaphragm carrier 18 by means of a screw stud 23 so that it can easily be exchanged.
  • a screw stud 23 By' this means a wide adaptation to the varying anatomic conditions of differently shaped cars is ensured; an ear piece shaped to suit the ear according to whether the auditory duct possesses a larger or smaller diameter may thus be screwed on position to which it is adjusted, by this pawl and notch locking device.
  • This device renders the readjusting of the diaphragm still easier than in the case of the arrangement illustrated in Fig. 8.
  • An abutment 22 in this case also prevents the diaphragm from being damaged.
  • a telephone receiver the combination of an L'-shaped casing, one arm of said casing being adapted to be inserted in the auditory duct, a telephone diaphragm and excitatlon coils both arranged in said arm and a permanent magnet arranged in the other arm.
  • a telephone receIVer the combmation of an L-shaped casing of non-magnetic material, one arm of said casing having substantially circular, thebther arm having rectangular cross section, a slotted partition subdividing the said casing in two chambers, each one arranged in one of said arms, a telephone diaphragm, excitation coils and pole-shoes disposed Within the chamber in said arm of circular cross section, a U-shaped permanent magnet arranged in the chamber in said arm of rectangular cross section, said pole-shoes bearing salcl excitation coils and means connecting the rear ends of said poleshoes and the ends of said magnet tothe walls of said casing.
  • a telephone receiver the combination of an L-shaped casing, one arm of said casing being adapted to be inserted in the auditory duct, a telephone diaphragm and excitation coils both arranged in said arm, and a permanent magnet arranged in the other arm of said casing, the weight being distributedin such a manner that the center of gravity lies in the arm to be inserted in the auditory duct.
  • a telephone receiver the combination of an L-shaped casing of non-magnetic material, one arm of said casing being adapted to be inserted in the auditory duct, poleshoes and excitation coils arranged in said arm, a telephone diaphragm in said arm adjustably arranged relatively to said poleshoes and a U-shaped magnet arranged in the other arm of said casing and connected with said pole-shoes.
  • a telephone receiver the combination of an L-shaped casing of non-magnetic material, one arm of said casing being adapted to be inserted in the auditory duct, poleshoes and excitation coils arranged in said arm, a telephone diaphragm in said arm adjustably arranged relatively to said poleshoes, an abutment preventing the moving of said diaphragm against said pole-shoes below a predetermined limit, and 'magnet arranged in the other a. telephone diaphragm of an U-shaped arm of said casing and connected with said pole-shoes.
  • a telephone receiver the combination of an L-shaped casing, one of its arms hayin cylindrical form and being adapted to be inserted in the auditory duct, the other arm having rectangular form, pole-shoes and excitation coils thereon disposed in said cylindrical arm and a U-shaped magnet in said rectangular arm connected to said pole-shoes, said cylindrical arm having a socket threaded to it, a diaphragm fastened in said socket and adjustable relatively to said pole-shoes by the turning of said threaded socket, means for limiting the extent of said adjustment and an ear piece remo-vably attached to said socket and operatively connected with said diaphragm.
  • a telephone receiver the combination of an L-shaped casing, one of its arms having cylindrical form and being adapted to be inserted in the auditory duct, the other arm having rectangular form, pole-shoes and excitation coils thereon disposed in said cylindrical arm and a U-shaped magnet in said rectangular arm connected to said pole-shoes, said cylindrical arm having a socket threaded to 1t, a diaphragm fastened in said socket and adjustable relatively to said pole-shoes by the turning of said threaded socket, means for limiting the extent of said adjustment and an ear piece removably attached to said socket and operatively connected with said diaphragm the center of gravity of the entire casing being located in its cylindrical arm.
