Description

  • The present invention relates to an in-ear phone.
  • In-ear phones have become very popular in recent years and are in particular used during vigorous activity like sport or the like. However, due to the different sizes of the human ears, the in-ear phones or channel-type ear phones will not fit into each ear equally well.
  • US 2008/0181444 A1 shows an in-ear communication device.
  • US 7,379,557 shows a headset with an auxiliary positioning device.
  • Therefore, in-ear phones are known which have stabilizing or securing means for stabilizing or securing the in-ear phone in the ear of the user.
  • It is an object of the present invention to provide an improved in-ear phone or channel-type ear phone which allows a stable wearing of the ear phone in a great variety of human ears.
  • This object is solved by an in-ear phone according to claim 1.
  • Accordingly, an in-ear phone having a housing for receiving an electro-acoustic transducer and a stabilizing unit is provided. The stabilizing unit comprises a first section fixedly connected to the housing and a second section being adjustable along a longitudinal direction of the stabilizing unit. The second section of the stabilizing unit comprises a first end and a second distal end. The second end is flexible and comprises a surface contact area for engaging in an upper concha of a user's ear. The second section remains in its position relative to the first section when no force is applied to the stabilizing unit. The length of the stabilizing unit is adjustable when the in-ear phone is placed inside in an ear of a user.
  • According to an aspect of the invention, the second section moves along a curved path relative to the first section when adjusting the length of the stabilizing unit.
  • According to a further aspect of the invention, the second section moves along a circular arc relative to the first section when adjusting the length of the stabilizing unit.
  • According to an aspect of the invention, the second end is implemented as a flexible tube-like element substantially perpendicular to the longitudinal direction of the stabilizing unit.
  • According to a further aspect of the invention, the second end is implemented as a curved adjustable arm. The curve of the second end is adapted to engage into an anti-helix of an ear of a user.
  • According to an aspect of the invention the in-ear phone comprises a flexible appendix which is attached to the flexible second and of the second section. The appendix points back from the second end of the second section substantially parallel to the longitudinal direction of the stabilizing unit and is directed towards the housing.
  • According to a further aspect of the invention the flexible appendix bulges when a force is applied to the flexible second end in the longitudinal direction of the stabilizing unit and the bulging causes to fill up the void inside the anti-helix of the ear of a user when the in-ear phone is worn in a human ear.
  • The present invention relates to the idea to provide an in-ear phone having a housing for receiving an electro-acoustic transducer and a stabilizing unit which is coupled to the housing for the electro-acoustic transducer. The stabilizing unit has an adjustable length to be able to fit securely into different kinds of ears of the user.
  • The stabilizing unit comprises a first end which is interacting with the housing for receiving the electro-acoustic transducer and a second end which is engaging in the ear of the user. The second end can comprise a flexible end of the stabilizing unit. This flexible end can be for example implemented as a flexible tube-like element. Preferably, the stabilizing unit can be adjusted in its length along its longitudinal axis.
  • The flexible end of the stabilizing unit is adapted to be in contact with the upper concha of the user's ear. The flexible end of the stabilizing unit is also used to increase the surface contact between the stabilizing unit and the upper concha of the ear. The second end of the stabilizing unit can also be implemented as a curved adjustable arm with an angle which is adapted to the anti-helix of the ear. In addition, the second end of the stabilizing unit can be implemented as a flexible stabilizer and with an increasing size when it is bended inside the anti-helix.

  • Fig. 1A shows a schematic representation of an in-ear phone according to a first embodiment. The in-ear phone 100 according to the first embodiment comprises a housing 110 for receiving the electro-acoustic transducer (not shown), a stabilizing unit 120 and an in-ear cushion 130 if the in-ear phone is implemented as a channel-type ear phone. The stabilizing unit 120 comprises a first section 121 fixedly connected to the housing 110 and a second adjustable section 122. The second section 122 comprises a first end 122a and a second end 122b. The first end 122a is arranged towards the first section 121. The second end 122b is arranged at the distal end of the second section 122. The stabilizing unit 120 comprises a longitudinal direction and the length of the stabilizing unit 120 (including the first and second section) is adjustable in the longitudinal direction, i.e. the stabilizing unit comprises an adjustable arm as second section 122. In other words, the distance between the distal ends of the first and the second section 120, 122 can be varied to adjust to different ears. At the second end 122b of the second section 122 of the stabilizing unit 120, a flexible tube-like stabilizer 126 is provided. This flexible tube-like stabilizer 126 will be in contact with the anti-helix of the user's ear. The second end 122b of the stabilizing unit, i. e. the flexible tube-like stabilizer can comprise a bend in order to improve the secure fitting of this second end in the anti-helix of the user's ear.
  • Fig. 1 B shows a schematic representation of the in-ear phone of Fig. 1 A inside a human ear. Here, the in-ear phone according to the first embodiment is placed in the ear 200 of the user. In case that the in-ear phone is implemented as a channel-type ear phone, the cushion 130 is placed inside an ear channel. The second end 122b of the second section 122 is in contact with the anti-helix 210 of the user's ear. As the length of the stabilizing unit 120 is adjustable, the in-ear phone according to the first embodiment can fit into almost every ear of a user.
  • An in-ear phone according to a second embodiment substantially corresponds to the in-ear phone according to the first embodiment. Therefore, the in-ear phone 100 comprises a housing 110 for receiving the electro-acoustic transducer (not shown), a stabilizing unit 120 and a cushion 130 if the in-ear phone is implemented as a channel-type ear phone. The stabilizing unit 120 comprises a second adjustable section 122 having a first end 122a and a second end 122b, wherein the second end 122b will be placed into the contact of the upper concha of the ear of the user. The main difference between the in-ear phone according to the first and the second embodiment is that the stabilizing unit and in particular the second end of the second section of the stabilizing unit has a different shape. Here, the second end of the second section of the stabilizing unit 120 is bend towards the housing 110 while the second end of the second section of the stabilizing unit 120 according to the first embodiment is bend substantially in parallel to the outer ear of a user.
  • Fig. 2A shows a schematic representation of an in-ear phone according to the second embodiment. The earphone according to the second embodiment substantially corresponds to the earphone according to the first embodiment. In particular, the arrangement of the in-ear cushion 130, the housing 110 and the first section 121 of the stabilizing unit 120 corresponds to the respective parts according to the first embodiment. Accordingly, merely the second section 122 of the stabilizing unit is different. The first section 121 of the stabilizing unit 120 will substantially and functionally correspond to the first section 121 of the stabilizing unit according to the first embodiment. While the tube-like stabilizer 126 at the second end of the second section of the stabilizing unit 120 according to the first embodiment is arranged in an angle substantially perpendicular to the longitudinal direction of the stabilizing unit, the second end of the second adjustable section 122 of the stabilizing unit 120 according to the second embodiment carries an appendix 122c substantially parallel to the longitudinal direction of the stabilization unit 120. The second end 122b of the second adjustable section 122 is preferred to be flexible and to allow a more comfortable and secure fitting of this second end into the upper concha of a user's ear.
  • As can be seen in Fig. 2A, the second end 122b of the stabilizing unit according to the second embodiment can be very flexible. The appendix 122c is attached to the outer end of the flexible second end 122b of the second section 122. The appendix 122c is flexible. It points back from the second end 122b of the second section 122 substantially parallel to the longitudinal direction of the stabilizing unit 120, directing towards the housing 110.

The second end 122b can be implemented according to the first, second or third embodiment of the in-ear phone 100.
  • The dashed line shows the second section 122 in a second operating position. In this second operating position the stabilizing unit 120 is elongated compared to the first operating position and the second end 122b of the second section is moved to position 122b'. The arrow 410 demonstrates the direction of the movement of the second section 122 relatively to the first section 121 when adjusting the length of the stabilizing unit 120. It can be seen that this movement does not follow a straight line but a curved path. Particularly the second end 122b tends towards the housing 110 when the stabilizing unit 120 is elongated by moving the second section 122 from the first operating position to the second operating position bringing its second end 122b to the second position 122b'.
