Definitions

  • the present invention relates to a chin strap headphones with two acoustic Transducers and with two brackets, at the top of each one of the transducers is attached and the upper ends are elastically removable from each other and the are connected together at their lower end.
  • Headphones are known to be used especially as chin guard headphones designed when circuit boards with electrical circuits attached to the headphones should be.
  • Known chin strap headphones have a small housing, which can be positioned under the chin in front of the user's chest and from which starting from two elastic temples in a slightly curved shape on the cheeks lead past to the ears.
  • There at the top ends of the brackets are acoustic Transducer attached.
  • the transducers are usually equipped with ear pads that the pressure of the transducers against the ears for the user comfortably and cushion softly.
  • the contact pressure is generated by the upper ends the bracket with the transducers apart and the bracket over their Length can be elastically deformed transversely, so that the then in the auricles of the User placed the ear pads of the acoustic transducers bouncy lightly into the Ears are pressed in, find a stop there and good acoustic transmission guarantee,
  • the invention is therefore based on the object of a chin strap headphones create that regardless of individual dimensions of the head anatomy of his User presses the acoustic transducer against the ear cups ensures that is strong enough for a secure hold and weak enough is so as not to be uncomfortable for the user.
  • a chin strap headphone has two acoustic transducers for each one ear and two brackets, at their upper ends for positioning on the ear each one of the transducers is attached.
  • the brackets are together at their lower ends connected and thus together form a bay which, when a user accesses the Chin strap headphones put on from ear to ear under the chin Leads through.
  • the upper ends of the brackets can be used to create Contact pressure of the transducers - preferably through pads between the transducer and the ear more elastic for the user spread over a larger area of the ear cups away from each other, preferably by placing the brackets over their Length are elastically deformable transversely.
  • the distance between the top ends of the temples - i.e. the Distance between the ear contact surfaces of the transducers - at the connection of the adjustable lower ends of the temples, especially before the chin strap headphones is created by a user.
  • the Travel of the bracket which, as described in relation to the prior art, the The transducer presses against the ears to the individual width of the Adjust the user's head (the distance of his ear cups from each other and there in particular the surface areas that are in contact with the listener when the handset is on Converters).
  • the distance does not change between the transducers at the upper end of the bracket, because this is when the Chin strap headphones of course dictated by the distance between the ears, but-and this also corresponds to the goal on which the invention is based - the preload the elastically removable upper ends of the bracket against the
  • the user's ear cups change by changing the spring deflection the bracket, and thus the contact pressure according to the invention is the transducer (or the pads, which are preferably attached to the transducers) against the pressure-sensitive ones User adjustable ear cups.
  • a hinge joint preferably forms the connection between the lower ones Ends of the bracket, which can be locked in any opening angle. So results an adjustable width of the bay formed by the brackets and consequently according to the invention an adjustable distance between the upper ends of the brackets, where the transducers are attached.
  • the brackets are from a rest position small angle between the brackets and small distance between them upper ends in a functional position with a larger angle between the brackets and greater distance between their upper ends movable, and a spring in The area of the connection clamps the brackets towards each other in the direction of the rest position in front.
  • the chin strap headphones according to the invention are spring-actuated in the space-saving rest position when the bracket is not in use by a user operated and moved apart.
  • the movement of the stirrups is preferred limited in the direction of the functional position by a stop that is to the invention Adjust the distance between the top ends of the brackets is adjustable. Because the angular position of the stop is so adjustable, that the bracket moved against the stop in the functional position Taking adjustable angles to each other by means of the stop is according to the invention also the distance between the transducers at the top of the bracket the adjustment of the stop adjustable.
  • the user therefore moves in this preferred embodiment of the invention Chin strap headphones from the rest position against the bias the spring - which is preferably a comparatively small spring constant has - up to the adjustable stop in the functional position. He is now bending the upper ends apart so that the brackets are elastic along with their length preferably larger spring constant than the spring - deform transversely, and then places the acoustic transducers in his ears at the top of the bracket. If the user now finds that the bracket is preloaded against its Ears too small, he moves the stop towards a smaller angle between the brackets, around the resilient deflection of the brackets - i.e. the contact pressure - enlarge against his ears on his head between the temples.
  • the spring - which is preferably a comparatively small spring constant has - up to the adjustable stop in the functional position. He is now bending the upper ends apart so that the brackets are elastic along with their length preferably larger spring constant than the spring - deform transversely, and then places the acoustic trans
  • the spring preferably pulls the stirrups into the rest position in such a way that in the Rest position a button e.g. is pressed to switch off the headphones.
  • a chin strap headphones with two straps 2 and two acoustic transducers 4 recognizable at the upper end of the bracket 2.
  • the brackets 2 are connected to one another at a housing 6 and thus form a bay open to the top.
  • the brackets 2 are arched outwards arched, and the acoustic transducers 4 at the top of the bracket 2 are after directed inside with ear cushions 8, which are also formed in the inside Bay show.
  • the ear pads 8 (made of rubber or elastic plastic) each have a passage 10 of two crossed Slits on to make a good acoustic connection from the transducers 4 through the To ensure ear pads 8 in the direction of the ears (not shown).
  • bracket 2 with the acoustic transducers 4 and the ear pads 8 are elastically removable from each other by the bracket 2 over their arcuate Length are elastically deformable transversely to the outside.
  • the Iron 2 formed bay expand elastically, and the ear pads 8 on the acoustic Transducers 4 can be used by the user in his ears, the Guide bracket 2 along the user's cheeks down to the chin where under the chin the housing 6 as a connection between the lower ends of the bracket 2nd rests on the user's chest (not shown).
  • the left of the bracket 2 is in a shaft 12, the one piece with a lid 14, which is the rear wall of the circular-cylindrical housing 6 forms.
  • On an axis 16 coaxial with the housing 6 is via a hinge joint the right of the bracket 2 articulated and so with the left of the bracket 2 through the Housing 6 connected.
  • a tension coil spring 18 In the interior of the housing 6 is a tension coil spring 18 with respect to the axis 16 in the circumferential direction between the right of the bracket 2 and the wall of the housing 6 forming the periphery of the housing 6 against biased clockwise about axis 16.
  • the spring 18 pulls the the bracket 2 on the right with a projection 22 which is on the bracket 2 on the right is formed, counterclockwise against a button (not shown) for Turn off the headphones.
  • the button is on a circuit board (not shown) arranged, which is in a plane perpendicular to the axis 16 above the here described elements is located in the housing 6.
  • the right of the bracket 2 is thus articulated in the housing 6 on the axis 16 coaxial therewith and can thus pivot differently from the left of the bracket 2 at different angles.
  • the right of the bracket 2 can swivel over an angle of approximately 15 ° with respect to the housing 6 by the right of the bracket 2 being guided out of the housing 6 through a correspondingly long slot 24 in the peripheral wall of the housing 6.
  • the wall of the elongated hole 24 serves as a stop and limit the range of movement of the right of the strap 2 against the left of the brackets 2 in the circumferential direction of the housing 6. In the extreme position of this movement range the counterclockwise direction, the spring 18 pulls the right hand of the brackets 2 in the Rest position in which the projection 22 actuates the button (not shown).
  • the extreme position of the right of the bracket 2 in a clockwise direction in the circumferential direction of the housing 6 - the position in which a user pulls the bracket 2 apart to put on the headphones - can be adjusted by means of an adjusting lever 26 which is also mounted on the axis 16 Pin 28, which engages in an elongated hole 30 extending in the circumferential direction about the axis 16, which is formed on the bracket 2 within the housing 6.
  • the lever 26, with which the pin 28 can be pivoted about the axis 16 in the slot 30, is limited in its pivoting range by a screw 32, which is inserted on the one hand through a hole in the lever 26 and on the other hand through a second slot 34, which also extends on the housing 6 in the circumferential direction.
  • the head of the screw 32 extends out of the housing 6 and can therefore be actuated from the outside in order to fix the lever 26 - adjustable about the axis 16 - when the screw 32 is tightened.
  • the pin 28 as part of the lever 26 can be pivoted in the elongated hole 30 of the right of the bracket 2 and serves as a stop for the right of the bracket 2 around the axis 16 to limit the mobility of the right of the bracket 2 in a clockwise direction. Then namely the edge of the elongated hole 30 abuts as part of the right of the bracket 2 against the pin 28 as part of the lever 26.
  • the described configuration limits the movability of the right of the bracket 2 relative to the left of the bracket 2 that the ends of the brackets 2 can only be removed from one another by an adjustable distance as described before the brackets 2 are deformed elastically, i.e. resiliently, and by this deformation the contact pressure of the ear cushions 8 against the ear cups (not shown) of the user produce.
  • This contact pressure is consequently adjustable by the described adjustability of the mobility of the stirrups 2 relative to one another, in that by determining the position of the stirrups 2 relative to one another before their resilient deflection, the spring travel of the stirrups can be individually adjusted, by which the stirrups 2 can be adjusted by the individual ear distance of a headphone user be deflected.
