Definitions

  • the invention relates to a headphone comprising a holding member, such as a headband, and at least one circumaural earphone.
  • a headphone comprises a headband and two earphones at the ends of the headband.
  • the headband keeps the headphone on the head by pressing the earphones against the head of the use when worn.
  • monaural headsets which only comprise one earphone and where the opposite end of the headband comprises small plate or T- or Y-shaped bar, which rests on the head beside the ear.
  • the earphones can be differently shaped.
  • Supra-aural earphones rest on the ear and circumaural earphones are designed to rest on the users head and surround the ear.
  • Both circumaural and supra-aural headphones can be provided with open-back ear cups or closed-back ear cups.
  • the open-back ear cups do not block out external noise and audio and leaks audio from the speaker to the surroundings.
  • the closed-back ear cups more efficiently blocks out external noise and do not leak audio in any significant amount.
  • This invention relates to circumaural headphones.
  • the earphone housing side that faces the user's head is normally provided with a ring-shaped soft ear cushion, that rest on the head around the ear. This cushion must provide adequate support to keep the headphone in place.
  • the ear cushion should also ensure a comfort wearing so the user does not feel a too strong pressure on the head around the ear, which may cause discomfort after a short time of wearing.
  • the ear cushion must have a certain softness to ensure this purpose.
  • the ear cushion When the headphone is a closed back headphone, and especially a headphone with so-called active noise cancellation, the ear cushion must also provide effective passive noise cancellation by providing an effective seal against the skin of the user to prevent that external noise enters the cavity enclosed by the ear cushion, the earphone housing side and the head of the user.
  • a soft ear cushion is able to adapt itself to the unevenness of the head surface around the ear and thereby provide a good sealing.
  • a soft ear cushion may cause the harder parts of the earphone housing to be felt through the compressed cushion which may cause discomfort. If the soft cushion is made thick enough to prevent this, it becomes inappropriate thick and/or "destroys" the supporting action, whereby the ear phone does not rest securely on around the ear.
  • a relatively soft ear cushion provides good sealing but less comfort, when it has a suitable thickness in relation to design purposes.
  • a relatively ear hard ear cushion provides a good support and good comfort but does not provide sufficient sealing.
  • the relatively hard foam material may itself have good sound attenuating properties but that may be "cancelled out" by poor sealing properties.
  • EP 2 858 380 discloses an earphone where the thickness of the earpad varies across the perimeter in order to adapt it to the head of user in order to improve sealing.
  • US 4,922,542 discloses a headphone where the earphones comprise a double annulus circumaural cushion in order to provide a good sealing.
  • US 2015/0092976 disclose a headphone with an ear cushion comprising two layers of compliant material. A first layer close to the head is relatively soft and a second layer close to the earphone housing is harder. This solution provides an attempt to combine comfort with good sealing.
  • a headphone comprises a first circumaural earphone and a holding member for holding the headphone on the head of the user and forcing the first earphone against the head of the user
  • the first earphone comprises an earphone housing with a first housing side facing the head of the user when worn, a first circumferential ear cushion with a first hardness and a first abutment face for abutting the head of the user, which first ear cushion together with the first housing side and the head of the user confines a first cavity
  • the first earphone on the first housing side beside the first ear cushion comprises a second ear cushion with a second hardness and a second abutment face for abutting the head of the user, and wherein the second hardness is larger than first hardness.
  • the complete the first ear cushion, the second ear cushion and the holding member are dimensioned, such that the first and second ear cushions abut the head.
  • the first abutment face is located at first distance from the first housing side and the second abutment face at a second distance from the first housing side, wherein the first distance is equal with the second distance, when the headphone is worn, and wherein the first distance is larger than the second distance in a relaxed state, when the earphone is not forced against the head of the user.
  • the first ear cushion may be ring-shaped and extend along the circumference of the earphone housing.
  • the second ear cushion may be arranged in the first cavity. Thud, the second ear cushion is hidden when the headphone is worn.
  • the second ear cushion may be ring-shaped like the first ear cushion.
  • the second earphone is adapted to not abut the head of the user in the area below the ear of the user. This area is relatively sensitive, and the user may feel less discomfort with this embodiment.
  • the second ear cushion is shaped as an inverted U, when the headset is worn and the user's head is in upright position.
  • the second ear cushion may alternatively be arranged outside the first cavity.
  • first ear cushion and second ear cushion comprise foam.
