Definitions

  • This invention relates to a headphone comprising a resilient strap and characterized in that the resilient element of the strap providing a mechanical connection of the two receivers is surrounded by a plastic covering, which has a tubular duct which is preferably disposed on the side facing off the head of the user and tightly encloses the lead electrically connecting the two receivers; this duct is provided with a preferably self-closing longitudinal slot to facilitate the introduction of the connecting lead.
  • push-on sleeves are provided on both ends of the plastic part of the strap to prevent the lead which connects the two receivers from being pulled out of the duct, these sleeves tightly enclose the two end portions.
  • the resilient bail consists of one or several bands of thin steel, which are bright or covered with leather or imitation leather.
  • lead to the receivers is formed by a branched cable so that a separate lead depends from each receiver and these leads combine to form a common cable after about 40 cm.
  • the disadvantages of this known arrangement consist mainly in that the leads to the receivers tend to become entangled and then cause unnecessary trouble. The repeated entangling and disentangling causes also damage to the leads by breakage so that the headphone cable must be replaced.
  • the cable for the headphone according to the invention comprising a resilient strap, consists of a simple, flexible double lead leading to one of the two receivers. From this receiver the lead is continued to the other receiver in a duct of the plastic covering surrounding the resilient element. In this way an entangling of the cable is prevented.
  • the electrical connection between the two receivers could be firmly installed in the plastic covering of the strap. It is more suitable, however, to provide in accordance with the invention for a replacement of the lead because otherwise it will be necessary to replace the entire strap in the case of a trouble which may be caused e.g., by a defect of material or by the application of force. For an eflicient manufacture it is also more suitable to insert a completely connected lead than to make soldered or screwed connections at the device itself.
  • FIG. 1 is an elevation showing the headphone according to the invention.
  • FIGS. 2 and 3 are transverse sectional views showing the resilient strap and
  • FIG. 4 is a perspective view showing an end sleeve.
  • the two receivers 1, 2 are carried by a resilient strap 3, which terminates in extensions 4, 5, which consists preferably of flat wire loops and to which the two receivers 1, 2 are slidably attached.
  • FIG. 2 is a transverse sectional view taken on line AB in FIG. 1 and showing the strap 3.
  • the preferably flat resilient element 8 is surrounded by a plastic covering 9, which is thicker on the side facing away from the head of the user and in this thicker portion has a duct 10.
  • This duct 1%) is intended to receive the connecting line between the two receivers.
  • the shape of the duct 10 is suitably determined in accordance with the cross-sectional shape of the lead to be accommodated. For the sake of simplicity the lead is in most cases round and has a circular cross-section.
  • the duct 10 On its upper side the duct 10 has a longitudinal slot, which may consist, e.g., of a straight longitudinal slot.
  • the slot 11 may also be made as is shown in FIG. 3, with overlapping parts. This embodiment is substantially equivalent with the embodiment shown hereinbefore. There are other possibilities for the design of the slot 11, of course, and it would go too far to list them all here. For instance, the slot 11 could be so wide that its Walls have a certain spacing apart and do not close, so that the lead can be inserted by hand, without any auxiliary device.
  • a headphone which comprises two receivers, a resilient strap carrying said two receivers and comprising a resilient element connecting said two receivers, a plastic covering surrounding said resilient element and defining a duct, said headphone comprising further a connecting lead electrically connecting said two receivers and disposed in said duct, said covering having a lonigtudinal slot communicating with said duct and facilitating the introduction of said lead into said duct.
