  The ear sets described in the above-mentioned "Patent Document 1" and "Patent Document 2" extend so that their ear hooks are substantially along the outer peripheral edge of the ear set main body, so that it can be configured compactly. However, there are the following problems.

  That is, when the user wears the earset, the optimum positional relationship between the microphone and the receiver is slightly different for each user because the skeletal structure of the head is different among users.

  However, in the ear sets described in the above-mentioned “Patent Document 1” and “Patent Document 2”, since the base end portion of the ear hook is fixed to the ear set body, the ear hook is hooked on the ear. When this happens, the position of the microphone and receiver of the earset body will be fixed uniformly. For this reason, there exists a problem that these microphones and receivers cannot be arranged in an optimal position.

  The present invention has been made in view of such circumstances, and in an earset in which an earhook is attached to an earset main body having a microphone and a receiver. Thus, it is an object of the present invention to provide an earset capable of arranging the microphone and the receiver at an optimal position when worn.

  The present invention is intended to achieve the above-mentioned object by devising the structure of the earset main body and the mounting structure of the earhook with respect thereto.

That is, the earset according to the present invention is
In an earset comprising an earset main body having a microphone and a receiver, and an ear hook attached to the earset main body,
A first casing portion in which the earset main body accommodates the microphone, and a shaft-shaped connecting portion that protrudes in a direction perpendicular to the predetermined direction at a position away from the microphone accommodating position in the first casing portion in the predetermined direction. And a second casing part fixed in a state in which the receiver is accommodated at the tip of the shaft-like connecting part,
A portion near the tip of the ear hook is formed so as to extend in a substantially C shape in a plane substantially perpendicular to the protruding direction of the shaft-like connecting portion, and the attachment of the ear hook to the ear set body is In the base end portion of the ear hook, the shaft is connected to the shaft-shaped connecting portion so as to be rotatable around the shaft-shaped connecting portion.

  The “first casing portion” is configured to accommodate the microphone, and has a size that allows the shaft-like connecting portion to protrude in a direction orthogonal to the predetermined direction at a position away from the microphone accommodating position in the predetermined direction. If it has, the specific shape, size, etc. will not be specifically limited.

  The term “predetermined direction” is a term used to clarify the positional relationship between the housing position of the microphone in the first casing portion and the shaft-like connecting portion and the protruding direction of the shaft-like connecting portion. “Predetermined direction” does not mean a specific direction.

  The above-mentioned “ear hook” has a specific shape such as a cross-sectional shape as long as a portion near the tip thereof is formed to extend in a substantially C shape in a plane substantially orthogonal to the protruding direction of the shaft-like connecting portion. The configuration is not particularly limited.

  As shown in the above configuration, the earset according to the present invention includes a first casing part in which the earset main body accommodates a microphone, and a position away from the microphone accommodating position in the first casing part in a predetermined direction. It has a configuration including a shaft-like connecting portion that protrudes in a direction orthogonal to the predetermined direction, and a second casing portion that is fixed in a state in which the receiver is accommodated at the tip of the shaft-like connecting portion, The ear hook attached to the ear set main body is formed so that a portion in the vicinity of the tip thereof extends in a substantially C shape in a plane substantially orthogonal to the protruding direction of the shaft-like connecting portion. The attachment to the main body is performed in such a manner that it can be rotated around the shaft-like connecting portion with respect to the shaft-like connecting portion of the first casing portion at the base end portion of the ear hook. , It is possible to obtain the following effects.

  That is, when the second casing portion that accommodates the receiver is pressed against the entrance portion of the user's external ear canal (that is, the ear canal), the first casing portion extends in the same direction as the external ear canal. In this state, the ear hook is pivoted upward from the front side of the ear (accurately, the pinna or ear shell) around the shaft-like connecting portion, thereby the vicinity of the tip of the ear hook. Can be hung on the top of the ear. Then, from this state, the microphone accommodated in the first casing portion is moved to an optimum position (for example, a sound collecting effect is obtained) by rotating the first casing portion around the shaft-like connecting portion to an appropriate angular position. (The highest position). In addition, at this time, since the second casing part is also rotated simultaneously by the rotation of the first casing part, the second casing part can be sufficiently adapted to the shape of the entrance portion of the ear canal by this rotation.

  On the other hand, when the earset is not mounted, the earset can be made compact by rotating the earhook around the shaft-like connecting portion to an angular position overlapping the first casing portion. At this time, the earset can be clipped to clothing or the like (for example, a pocket of a shirt) using the gap between the first casing portion and the earhook.

  As described above, according to the present invention, in an earset in which an earhook is attached to an earset main body having a microphone and a receiver, the earset is configured in a compact configuration when not mounted, and the microphone and receiver are mounted when mounted. It can be arranged at an optimal position.

  In the above configuration, if the ear hook is attached to the ear set main body in such a manner that it can be attached to and detached from the shaft-like connecting portion, the ear hook is attached to the shaft-like connecting portion with the front and back reversed. This makes it possible to use the ear set for both the left and right ears. At that time, the specific configuration for detachably attaching the ear hook to the shaft-like connecting portion is not limited to a specific configuration.

  In the above configuration, if the bulging portion that bulges in the same direction as the protruding direction of the shaft-like coupling portion is formed at the microphone housing position in the first casing portion, the following operational effects are obtained. Obtainable.

  That is, when an ear set in a state where the ear hook is rotated to an angular position overlapping with the first casing portion is clipped to clothing or the like using the gap between the first casing portion and the ear hook, Clothing or the like can be securely sandwiched between the bulging portion of the first casing portion and the ear hook, thereby preventing the earset from falling.

  In the above configuration, if the tip portion of the ear hook is formed as a large-diameter spherical portion, when the ear hook is rotated around the shaft-like connecting portion and the portion near the tip is hung on the upper portion of the ear The large-diameter spherical portion can be positioned by pressing against the auricular node (that is, the recessed portion on the upper back of the ear), and thus the ear hook can be securely locked.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a front view showing an earset 10 according to an embodiment of the present invention. 2 is a view in the direction of arrow II in FIG. 1, and FIG. 3 is a view in the direction of arrow III in FIG. FIG. 4 is a perspective view showing the earset 10.

Further, a rectangular opening is formed in the side wall of the intermediate portion, and the power switch 40 is disposed in the rectangular opening so as to be electrically connected to the printed wiring board 38. .

  The microphone 32 is accommodated in the tapered portion of the first casing portion 22 in the vicinity of the lower end thereof so as to be electrically connected to the printed wiring board 38. Further, in the back wall of the taper portion, the portion located on the back side of the accommodation position of the microphone 32 bulges toward the back side (that is, in the same direction as the protruding direction of the shaft-like connecting portion 24). A bulging portion 22b is formed. At this time, the bulging portion 22 b is formed so as to protrude about 1 mm toward the back side from the other portions of the first casing portion 22. Furthermore, a sound collection opening 22c is formed in a portion of the back wall of the taper portion located near the lower portion of the bulging portion 22b.

  The shaft-like connecting portion 24 is configured as a boss having an outer diameter of about 4 mm and an inner diameter of about 2 mm, and is formed integrally with the back side half 22 </ b> B of the first casing portion 22. And this axial connection part 24 is comprised so that the axial length between the 1st and 2nd casing parts 22 and 26 may be set to about 4 mm, when the 2nd casing part 26 is attached to the front-end | tip part. Yes.

  The second casing portion 26 is made of a synthetic resin, and is formed by assembling the front side half 26A and the back side half 26B, and has a circular shape when viewed from the front. At this time, the outer diameter of the second casing portion 26 is set to a value of about 16 mm, which is slightly smaller than the outer diameter of the dome-shaped cap 22C. The receiver 34 is accommodated in the second casing portion 26 so as to be electrically connected to the printed wiring board 38. The electrical connection between the receiver 34 and the printed wiring board 38 is performed by passing the wiring through the cylindrical space of the shaft-like connecting portion 24.

  The front half 26A is formed so as to protrude in a substantially conical shape toward the front side, and is fixed to the tip end portion of the shaft-like connecting portion 24 by press-fitting or welding at the center thereof. A pressure adjusting hole 26a is formed in the upper part of the front half 26A. On the other hand, the back half 26B has a central portion formed in a flat shape and a peripheral portion formed in an annular curved surface, and a sound emitting hole 26b is formed at a position slightly below the central portion. Is formed.

  The ear hook 14 is made of a synthetic resin, and is formed so that the tip vicinity portion 14a extends in a substantially C shape in a front view (that is, in a plane orthogonal to the protruding direction of the shaft-like connecting portion 24). As a whole, it has a substantially “?” Shape. At this time, the ear hook 14 has a general section formed with a circular section having a constant diameter of about 3 mm, and a tip section formed as a large-diameter spherical section 14 b with a spherical shape of about 6 mm in diameter.

  Then, the ear hook 14 is attached to the ear set main body 12 by rotating around the shaft-like connecting portion 24 with respect to the shaft-like connecting portion 24 of the ear set main body 12 at the base end portion 14 c of the ear hook 14. In order to achieve this, which is performed in a movable manner, the base end portion 14c of the ear hook 14 is formed in a C-shaped tube shape in a front view, and is elastically deformed so that the notch portion expands. The shaft-like connecting portion 24 is fitted.

  At this time, the base end portion 14c has a tube length set to a value of about 4 mm, and an inner diameter set to a value of about 4 mm. As a result, the ear hook 14 is configured to be rotatable with respect to the shaft-like connecting portion 24, and is maintained stationary at an arbitrary rotation angle position by friction with the shaft-like connecting portion 24. To get.

  Further, when the ear hook 14 is rotated counterclockwise to the position indicated by a two-dot chain line in FIG. 3, the large-diameter spherical portion 14 b comes into contact with the first casing portion 22 of the ear set body 12, The ear hook 14 is positioned at a position indicated by a two-dot chain line. At this time, the vicinity 14a of the tip of the ear hook 14 comes into contact with the bulging portion 22b of the first casing portion 22 and slightly elastically deforms to the back side.

  Next, the effect of this embodiment is demonstrated.

  FIG. 5 is a diagram illustrating a situation when the user wears the earset 10 on the right ear 2.

  First, as shown in FIG. 5A, the earset body 12 of the earset 10 is held by hand and the second casing portion 26 is pressed against the entrance portion of the ear canal of the right ear 2. At this time, the second casing portion 26 can be adapted to the shape of the entrance portion of the ear canal because the peripheral portion of the rear half 26B is formed in an annular curved surface.

  When the second casing portion 26 is pressed against the entrance portion of the ear canal of the right ear 2, the shaft-like connecting portion 24 extends in substantially the same direction as the ear canal. At that time, as shown by a two-dot chain line in the figure, the ear hook 14 is rotated in advance around the shaft-like connecting portion 24 to a position on the front side of the right ear 2 to attach the earset body 12. Try not to get in the way.

  Then, by rotating the ear hook 14 on the front side of the right ear 2 upward around the shaft-like connecting portion 24 as indicated by an arrow in the figure, the tip vicinity portion 14a is moved to the upper part of the right ear 2. Hang on. At that time, since the tip portion of the ear hook 14 is formed as a large-diameter spherical portion 14b, when the portion 14a near the tip is hung on the upper part of the right ear 2, the large-diameter spherical portion 14b becomes an auricular nodule. 2a enters into the recess, and the ear hook 14 is reliably locked.

  Next, as shown in FIG. 4B, the first casing portion 22 of the earset body 12 is rotated around the shaft-like connecting portion 24 to an appropriate angular position. Thereby, the microphone 32 accommodated in the first casing portion 22 is arranged at an optimal position (for example, a position close to the user's mouth 4 so that the sound collecting effect is maximized).

  Since the second casing part 26 is also simultaneously rotated by the rotation of the first casing part 22, the second casing part 26 can be sufficiently adapted to the shape of the entrance part of the ear canal. At this time, if the first casing portion 22 is reciprocated several times, the familiarity of the second casing portion 26 can be further improved.

  On the other hand, when the earset 10 is not attached, the earset 10 can be made compact by rotating the earhook 14 around the shaft-like connecting portion 24 to an angular position overlapping the first casing portion 22. be able to. At this time, the ear set 10 can be clipped to clothing or the like (for example, a pocket of a shirt) using the gap between the first casing portion 22 and the ear hook 14.

  As described above, according to the present embodiment, the earset 10 in which the earhook 14 is attached to the earset main body 12 having the microphone 32 and the receiver 34 is mounted with a compact configuration when the earset 14 is not mounted. Sometimes, the microphone 32 and the receiver 34 can be placed at optimal positions.

  Moreover, the earset 10 according to the present embodiment is configured such that the earhook 14 is attached to the earset main body 12 in a manner that it can be attached to and detached from the shaft-like connecting portion 24. The hook 14 can be attached to the shaft-like connecting portion 24 with the front and back reversed, and the earset 10 can also be used for the left ear. At this time, the base end portion 14c of the ear hook 14 is configured in a C-shape when viewed from the front. The base end portion 14c is elastically deformed so that the cutout portion expands and is fitted into the shaft-like connecting portion 24. Therefore, the ear hook 14 can be easily attached and detached.

  Further, the ear set 10 according to the present embodiment is configured such that the ear hook 14 is maintained in a stationary state at an arbitrary rotation angle position with respect to the shaft-like connecting portion 24. Inadvertent rotation can be prevented, and thus the earset 10 can be handled easily.

  Furthermore, the ear set 10 according to the present embodiment has a bulging portion 22 b that bulges to the back side at a portion located on the back side of the accommodation position of the microphone 32 on the back wall of the first casing portion 22. Therefore, the ear set 10 in a state in which the ear hook 14 is rotated to an angular position overlapping with the first casing portion 22 is used for clothing, etc. using the gap between the first casing portion 22 and the ear hook 14. When clipped, the garment or the like can be securely sandwiched between the bulging portion 22b of the first casing portion 22 and the vicinity of the tip 14a of the ear hook 14, thereby preventing the earset 10 from falling. Can be planned.

  At that time, as shown in FIG. 2, the bulging portion 22b of the first casing portion 22 comes into contact with the tip vicinity portion 14a when the ear hook 14 is rotated to an angular position overlapping the first casing portion 22. As a result, the ear hook 14 is elastically deformed slightly to the back side, so that a sufficient clip effect on clothing can be secured and the ear set 10 can be reliably prevented from falling. .

  Further, when the ear hook 14 is rotated counterclockwise to the position indicated by a two-dot chain line in FIG. 3, the large-diameter spherical portion 14 b comes into contact with the first casing portion 22 of the ear set body 12 and the ear hook 14 Since 14 is positioned at a position indicated by a two-dot chain line, the ear hook 14 can be easily rotated to an optimum angular position when the ear set 10 is not attached.

  Furthermore, in the earset 10 according to the present embodiment, the first casing portion 22 of the earset main body 12 is formed in a substantially band plate shape having a tapered portion. The operability as a lever can be enhanced. However, the first casing portion 22 may have a configuration other than this (for example, a disc shape or a substantially elliptic plate shape).

  In addition, the numerical value shown as a specification in the said embodiment is only an example, and of course, you may set these to a different value suitably.
