Definitions

  • an object of the present invention is to improve the wearing stability of a full-cover type earpiece and an earphone equipped with the earpiece.
  • the aspect of the present invention has the following configuration.
  • the full-cover type earpiece according to the aspect of the present invention covers the entire outer periphery of the case accommodating the speaker having the yoke supporting the vibrating membrane from the outside in the direction orthogonal to the axis of the yoke, and is said to be in use.
  • the entire outer circumference of the case accommodating the speaker is covered from the outside in the direction orthogonal to the axis of the yoke, and is viewed from the direction along the axis in the used state.
  • the following effects are obtained by providing a cover portion having a substantially oval shape extending from the tragus facing the user's concha cavity toward the tragus. Since the entire outer circumference of the case is covered by the cover, the earpiece feels soft when the earpiece is used (when the earpiece is attached to the ear).
  • the case has an inner case located on the inner peripheral side of the case and an outer peripheral portion of the inner case so as to be rotatable relative to the inner case around an axis.
  • the full-cover type earpiece has an opening for being detachably attached to the case, and the opening is the case when viewed from the direction along the axis.
  • the opening of the earpiece and the case are in close contact with each other, it is possible to suppress the formation of a gap that causes sound leakage.
  • the audio signal is supplied from an electronic device via a cord 40
  • the audio signal is supplied to the coil 15 via a lead wire.
  • the vibrating film 9 vibrates due to the displacement of the coil 15.

  • a folded-back portion 80 that is folded back from the tip end portion of the through-cylinder body 60 is provided.
  • the covering portion 50, the sound passage cylinder 60, the annular convex portion 70, and the folded portion 80 are integrally formed of the same elastic material (for example, silicone rubber) (see FIG. 8).
  • the covering portion 50 is formed on the tragus contact portion 51 for contacting the tragus 102 facing the user's tragus cavity 101 and the tragus 104 connected to the pair 103 facing the tragus 101. It is provided with a tragus contact portion 52 for contacting (see FIG. 11).
  • the cover portion 50 is formed so that the wall thickness (the radial thickness of the cover portion 50) is larger at the tragus contact portion 52 than at the tragus contact portion 51.
  • the earpiece 5 since the distance between the operating point and the fixed point is long by the length of the second sound passage portion 62, the earpiece 5 can be made difficult to come off.
  • the first sound passage portion 61 can be inserted into the depth of the ear canal 100 by the length of the second sound passage portion 62, so that the intrusion of external noise can be suppressed.

  • the first sound passage portion 61 can be inserted into the depth of the ear canal 100, and the second sound passage portion 62 can be interposed in a wide range near the entrance of the ear canal 100, so that external noise can be prevented from entering. It can be suppressed.
  • the length H1 of the long axis of the covering portion 50 having a substantially elliptical shape when viewed from the direction along the axis C1 is 15.5 mm or more and 17.5 mm or less, thereby achieving the following effects. ..
  • the mounting stability can be further improved as compared with the case where the length H1 of the long axis of the covering portion 50 having a substantially oval shape is less than 15.5 mm or more than 17.5 mm.
  • the gap of the concha cavity 101 can be made as small as possible. Therefore, the earpiece 5 is less likely to come out of the ear canal 100, and the sealed state can be maintained.
  • the folded-back portion 80 is integrally formed of the same elastic material as the sound transmission cylinder 60 , but the present invention is not limited to this.
  • the folded-back portion 80 may be detachably attached to the sound transmission cylinder 60 as an ear tip.
  • the sound communication cylinder 60 has been described with an example of including the first sound communication part 61 and the second sound communication part 62, but the present invention is not limited to this.
  • the sound communication cylinder 60 when the sound communication cylinder is shortened for a person with small ears, the sound communication cylinder 60 does not have to have the second sound communication portion 62.

Abstract

Un mode de réalisation de la présente invention concerne un écouteur 25 qui comprend : une section de couvercle 50 qui a une forme sensiblement ovale s'étendant à partir du tragus 102 en face de la cavité de conque 101 d'un utilisateur vers l'antitragus 103 lorsqu'il est vu tout en étant utilisé depuis une direction le long de l'axe C1 d'une culasse 10 pour supporter une membrane vibrante 9 et qui recouvre, depuis l'extérieur dans une direction orthogonale à l'axe C1, toute la circonférence extérieure d'un boîtier 3 dans lequel est logé un haut-parleur 2 comprenant la culasse 10 ; un corps cylindrique de transmission de son 60 qui a une forme cylindrique faisant saillie à partir d'une partie dans la section de couvercle 50 faisant face à la membrane vibrante 9 vers le côté opposé de la membrane vibrante 9 à partir de celui de la culasse, et qui sert à transmettre le son émis par le haut-parleur 2 vers le conduit auditif 100 dans l'oreille de l'utilisateur ; et une saillie annulaire 70 ayant une forme annulaire faisant saillie à partir de la circonférence interne de la section de couvercle 50 vers le côté opposé de la culasse 10 à partir de celui de la membrane vibrante 9 de façon à pouvoir supporter la section de circonférence externe du boîtier 3.
