Definitions

  • the disclosure relates to an earphone comprising a body and a ventilation duct extending at least partially through the body.
  • the earphone may comprise electronic hear-through, i.e. microphones and loudspeakers being used to feed ambient sounds into the ear canal.
  • the earphone comprises electronically-controlled ventilation using an air vent which is opened and closed electronically. This allows air to flow freely, at least periodically, but the solution is complex and expensive to implement with reliability.
  • both of these solutions require additional components, e.g. hardware such as microphones and digital signal processors, and they require electric power in order to operate, which may not be possible in true wireless stereo headsets.
  • an earphone comprising a body comprising a first side, a second side, and a peripheral surface extending between the first side and the second side, a center axis of the body extending from the first side to the second side, and a ventilation duct extending at least partially through the body in a direction of the center axis of the body, the ventilation duct comprising a first opening, second opening, and a ventilation path extending between the first opening and the second opening, the first opening and the second opening allowing air flow through the ventilation path, the ventilation path being closeable and openable, during use of the earphone, by means of manual movement of at least a part of the earphone between a closed position and an open position.
  • the first opening is located at the first side of the body and the second opening is located at the second side of the body.
  • the first opening is located at the peripheral surface of the body and the second opening is located at the second side of the body.
  • the ventilation duct extends through an interior of the body, such that the ventilation path forms a closed channel extending through the body, providing an earphone with excellent insulating properties against ambient sound.
  • the ventilation duct extends along the peripheral surface of the body, such that the ventilation path forms an open groove in the body, which facilitates a simple manufacturing process as well as a reliable and easy-to-operate earphone.
  • the earphone further comprises a moveable member adapted for closing and opening the first opening of the ventilation duct, the moveable member being connected to the body adjacent the first opening, providing an earphone in which the moveable part is not in direct contact with the ear canal and which therefore may be more comfortable for the user during operation.
  • the moveable member is one of pivotable or rotatable, between the closed position and the open position, in a plane extending perpendicular to the center axis of the body, or the moveable member is axially displaceable, between the closed position and the open position, in the direction of the center axis, facilitating an easy-to-reach and easy-to-operate opening and closing mechanism.
  • the moveable member comprises a throughgoing opening at least partially overlapping the first opening in the open position, providing a reliable connection between the ventilation duct and the exterior.
  • the earphone further comprises a fixed member, fixedly connected to the body, the moveable member being arranged between the body and the fixed member, the fixed member comprising at least one recess at least partially overlapping the throughgoing opening of the moveable member in the open position, facilitating high stability of the moveable member also during movement.
  • the moveable member is connected to the body by means of a pivot, a longitudinal axis of the pivot extending parallel with, and offset from, the center axis of the body, such that the moveable member is eccentrically pivotable in relation to the body, facilitating a very easy-to-operate earphone as well as a small form factor, which is particularly important for true wireless earphones.
  • the moveable member is connected to the body by means of a rotation shaft, wherein a longitudinal axis of the rotation shaft coincides with the center axis of the body, facilitating an earphone which has the same outer appearance and dimensions regardless of if it is in the open position or the closed position.
  • the moveable member is solid and connected to the body by means of a spring arrangement, the moveable member being moveable between the closed position and the open position in the direction of the center axis, facilitating a simple and inexpensive earphone.
  • a headset comprising at least one earphone according to the above, wherein the second opening of the earphone is adapted for placement adjacent or within an ear canal of a user, and the first opening of the earphone is adapted for placement outside of the ear canal such that at least a part of the earphone can be moved manually between a closed position and an open position by the user.
  • This allows the user to choose when to be well isolated from ambient sounds, and when to ventilate, without using electronics.
  • the headset is less power consuming and more reliable than electronically operated prior art.
  • a method of manually opening and closing a ventilation duct of an earphone according to the above when placed in an ear of a user comprising: manually applying pressure to the earphone such that at least a part of the earphone is moved between a closed position and an open position.
  • the method allows the user to choose when to be well isolated from ambient sounds, and when to ventilate, by means of a simple manual move and without using electronics.
  • manually applying pressure comprises the user rotating at least one of the body and the moveable member of the earphone, facilitating an easy-to-reach and easy-to -operate opening and closing mechanism.
  • manually applying pressure comprises the user pushing the moveable member of the earphone momentarily in the direction of the center axis of the body of the earphone, facilitating a simple and inexpensive earphone.

Abstract

La présente invention concerne un écouteur (1) qui comprend un corps (2) comprenant un premier côté (2a), un second côté (2b), et une surface périphérique (2c) s'étendant entre le premier côté (2a) et le second côté (2b), un axe central (A1) du corps (2) s'étendant depuis le premier côté (2a) vers le second côté (2b), et un conduit de ventilation (3) s'étendant au moins partiellement à travers le corps (2) dans une direction de l'axe central (Al) du corps (2). Le conduit de ventilation (3) comprend une première ouverture (3a), une deuxième ouverture (3b), et une voie de ventilation (3c) s'étendant entre la première ouverture (3a) et la deuxième ouverture (3b). La première ouverture (3 a) et la seconde ouverture (3b) permettent un écoulement d'air à travers le trajet de ventilation (3c). Le trajet de ventilation (3c) peut être fermé et ouvert, pendant l'utilisation de l'écouteur (1), au moyen d'un mouvement manuel d'au moins une partie de l'écouteur (1) entre une position fermée (P1) et une position ouverte (P2). Ceci permet à l'utilisateur de choisir lorsqu'il souhaite être bien isolé des sons ambiants, et lorsque qu'il souhaite une ventilation, sans utiliser d'électronique.
