Definitions

  • the present invention has reference to a microtelephone set for persons who telephone to a large extent and who therefore apply the microtelephone and the telephone on the head more permanently.
  • a breast plate transmitter together with a head telephone is a set which is used to :a large extent by telephone operators.
  • the set is very disadvantageous, partly because the same consists of two parts, and thus is inconvenient to put on and take 01T, and partly because the microphone is not hygienic, because it presses on the breast causing the operator to transpire, soils the clothes, the long mouth piece further bringing about bad transmission characteristics of the microphone.
  • the long mouth piece is also disturbing when writing. Toll operators can therefor only with difficulty use such arrangements.
  • the present invention has for its object to avoid the said inconveniences and consists of apparatus wherein a head microtelephone is provided with a microphone which is rotatably mounted on the telephone by means cf a bearing which is arranged in such a way that rotation of the microphone in relation to a telephone only can take place in one plane.
  • a head microtelephone is provided with a microphone which is rotatably mounted on the telephone by means cf a bearing which is arranged in such a way that rotation of the microphone in relation to a telephone only can take place in one plane.
  • the telephone is connected with a clip which is to be applied on the head of the speaker by means of a joint for instance a ball joint which makes it possible to rotate the telephone in rrelation to the clip in several planes.
  • the ball joint in accordance with the invention thus performs, due to its arrangement between the telephone and the head clip, a number of tasks.
  • the ball joint provides for the adjustment of the telephone to the ear and enables the microphone to be brought in a plane through the ear and the mouth perpendicular to the ear plane in substituting the ball joint of the known construction with a rotatable joint.
  • the rotatable joint at the microphone in the known construction is avoided and the whole microphone part can be made in one piece thus enabling the use of mculdable material.
  • the head set also may be used as an ordinary microtelephone.
  • Fig. l is a perspective view of a head clip and a microtelephone embodying the invention.
  • Fig. 2 is a perspective view of a portion of the clip.
  • Fig. 3 is a perspective view of the microtelephone disengaged from the head clip.
  • Fig. 4 is a diagrammatic perspective View showing the manner in which the head set is supported by an operator when writing.
  • Fig. 5 is a similar view showing the microtelephone supported on a different side of the head.
  • Fig. 6 is a perspective view illustrating the manner in which the microtelephone may be adjusted.
  • an embodiment of the invention consists of a head clip I, a telephone 3 applied to the same by means of a ball joint 2 and a microphone part 1 joined to the telephone 3 by means of bearings 4 and a pin 6.
  • the telephone may be constructed in a known manner.
  • the telephone housing may be formed of suitable material such as a resinous compound,v the4 walls being provided with the above mentioned bearings 4.
  • the microphone part 'l is formed in the shape of a spoon and may be formed of a suitable resinous compound or other moulded material.
  • the part 'l is preferably hollow in the shaft portion 8 and an integral part 9 forms a cup.
  • the whole microphone part is at its concave side covered by means of a thin plate 5 of insulating material whereby a closed housing for the microphone capsule yand for the conductors between the same and the telephone is obtained.
  • the telephone cord I0 is attached to the telephone box and the conductors to the microphone are suitably conducted from the telephone box to the microphone and it is possible either to use a flexible conductor at the joint between the telephone and the microphone parts or a construction with slip rings.
  • the microphone part by means of resinous compound is electrically insulated and thus prevents electrical shocks vfrom reaching the operator. It has a curved form which can follow the form of the face.
  • the cupshaped part 9 constitutes a good resonance chamber for the microphone box. Good transmission characteristics are thus obtained as compared with microphones with funuels, or microphones which'are standing free, the sound being damped in the iirst mentioned case, while there is no resonance chamber for a microphone in the second case. Further the whole set has been found to be very light. A comparison with the lightest of the known head microphones shows a diminishing of thev weight by lil-15%. Due to the fact that 'the head microphone is formed as a head microfphone the application of the same is simplified,
  • microtelephone being also usable as a normal microtelephone, the ball joint being therefore made easily disengageable.
  • the joint is according to the invention also formed so as to actuate an electrical contact.
  • The) arrangement may be such that the microphone part, as shown in Fig. 1, when rotated also swings a cam Il which by means of a pin I2 in the telephone box wall I3 actuates a contact arrangement I4 in the telephone box.
  • the contact arrangement may then be electrically connected in the same Way as a normal switch hook contact or it may be arranged only to break the microphone circuit.
  • a head telephone set which is arranged in this manner may also be doubled so as to allow the service of two telephone connections by the operator by pushing out the one or the other microtelephone.
  • a head clip In a telephone head set, a head clip, a telephone box. a joint ⁇ between said clip and said box permitting adjustment of the telephone box in relation to the head clip in several planes, a microphone part containing a microphone capsule, and a joint between said microphone part and said telephone box limiting adjustment of the microphone part to movement in relation to the telephone box in one plane only, said plane being perpendicular to the ear-plane.
  • a microtelephonic head set in accordance with claimrl in which the joint between said clip .and said box consists of a disengageable ball joint, the axis of said ball joint being perpendicular to the ear plane.
