Definitions

  • acoustic output device that is attached to the ear and used as headphones or earphones to output sound from the acoustic output unit.
  • the acoustic output device is used outdoors in addition to the mode used indoors. Is also increasing.
  • the opening / closing lid is housed in the electric unit at an open position where the intake hole is opened.
  • the acoustic output device shown below is provided with a drive unit and an electric unit, and the drive unit is formed in an annular shape, for example, an annular shape.
  • the axial direction of the drive unit is indicated.
  • the left-right direction shall indicate the front-back, up-down, left-right directions.
  • the external ear canal 113a which is the entrance of the external auditory canal 113, exists in the portion between the antitragus 110 and the tragus 111, and the external auditory canal 113 is communicated with the eardrum, the semicircular canal, or the like.
  • the acoustic output device 1 is used, for example, as a pair, one for the left ear and the other for the right ear. However, the sound may be heard using one sound output device 1.
  • the acoustic output device 1 is composed of necessary parts arranged inside the housing 2, and the housing 2 is composed of a first case 3 and a second case 4.
  • An operation unit (not shown) is arranged in the housing 2.
  • the operation unit may be, for example, a push button type operation unit or a sensitive operation unit such as a touch panel.
  • the lower end portion of the second case 4 is coupled to the upper end portion of the first case 3, and the protruding portion 6b is located outside the drive unit 5 in the left-right direction. Therefore, a step portion D is formed between one end portion 6a and the drive unit 5.
  • the helix leg 103 is positioned at the step portion D.
  • the holder 20 and the battery 21 are arranged inside the inner arrangement portion 15, and the battery 21 is held in the holder 20.
  • the battery 21 is connected to the main board 19 by the contact portion 19b.
  • the attached portion 26 is elastically deformed to a state where the diameter becomes large and elastically restored to a state where the diameter becomes small, so that the attached portion 26 is attached to the inner arrangement portion 15 in a state of being inserted into the mounting groove 15c.
  • the direction of displacement by angle ⁇ is the direction of displacement toward the lower leg 107 of the antihelix with respect to the antihelix 105. It is held in a stable state by the edge of the lower leg 107, and a stable wearing state of the sound output device 1 with respect to the ear 100 can be ensured.
  • the acoustic output device 1A is an example in which a first opening / closing lid 31 for opening / closing the intake hole 5a is provided.
  • the insertion portion 44 is inserted into the ear canal 113 while the acoustic output device 1 is attached to the ear 100. Therefore, the external sound taken in from the intake hole 5a passes through the internal space of the insertion portion 44, passes through the sound holes 46a, 46a, ..., And passes through the ear canal 113 toward the eardrum.
  • the present technology can be configured as follows.
  • the electric unit is formed in a shape having a central axis, and is formed.
  • the acoustic output device according to any one of (1) to (6) above, wherein the central axis of the electric unit is inclined with respect to the central axis of the intake hole.
