Description

  The present invention relates to a headphone for wearing on a head to listen to sound such as music and conversation.

  When wearing headphones while wearing glasses such as sunglasses, the headphone unit is put on the ear with the glasses worn on the ear, so the wearing feeling is poor and the appearance is not stylish. Therefore, various improvements have been proposed when combining glasses with headphones.

For example, Patent Document 1 describes that a notch portion in which a position for attaching spectacles and an earring is notched is formed on pads attached to left and right housings incorporating a speaker unit. It can be removed. Japanese Patent Application Laid-Open No. H10-228561 describes that glasses portions covering both eyes are rotatably connected to both lower ends of a hair band portion of a headphone. Patent Document 3 describes that headphones are attached to a spectacle frame via an angle adjustment mechanism. Further, Patent Document 4 describes that a headband is provided so as to be able to reciprocate from the top of the head to the forehead so as to be rotatable, and an eyeglass part is attached to the headband.

  In the above-mentioned prior literature, by attaching the glasses part to the headphone headband or attaching the headphone speaker part to the spectacle frame, it is intended to avoid the poor wearing feeling when wearing the headphones. However, when the spectacles part is attached to the headband, the spectacle part to be attached is limited to sunglasses or the like.

  For example, when wearing spectacles with a degree, it is necessary to accurately set the positional relationship between the spectacle lens and the eyes, but the spectacles described in the above-mentioned prior art can be turned up and down. The positional relationship in the front-rear direction between the eyeglass part and the eyes cannot be adjusted. In addition, since the eyeglass part easily moves up and down, it is not suitable for use with prescription eyeglasses.

  When the speaker unit is attached to the spectacle frame, it can also be used with spectacles, but the weight of the speaker unit is added to the spectacle frame, and the nose and ears supporting the spectacle frame are compressed. It is inevitable that the wearing feeling will be worsened.

  Therefore, an object of the present invention is to provide a headphone that can be mounted by adjusting the position of a spectacle frame.

  The headphone according to the present invention has a support frame body mounted on the head, a pair of headphone units attached to the support frame body, and one end portion rotatably attached to the support frame body above each headphone unit. A pair of angle adjustment members that can be held at a predetermined angular position, and a pair of angle adjustment members that are rotatably attached at one end to the other ends of the angle adjustment members and that are detachably attached to the other end. And a length adjusting member. Further, the angle adjusting member is characterized in that a ball portion formed at one end portion is fitted in a ball receiving portion provided in the support frame and is rotatably attached. Further, the rotation range of the angle adjusting member is restricted so as to rotate toward the upper front side of the head by the opening peripheral edge of the ball receiving portion. Further, the length adjusting member is configured such that either one of a front member to which the spectacle frame is detachably attached and a rear member having one end rotatably attached to the support frame is front and rear with respect to the other. It is provided with an engaging portion that is slidably mounted in a direction and holds both members in a predetermined positional relationship. Furthermore, the headphone unit is a bone conduction unit.

  The present invention includes the above-described configuration, so that the spectacle frame is attached to the headphones via the angle adjustment member that is rotatably attached to the support frame and the length adjustment member that is rotatably attached to the angle adjustment member. Therefore, it is possible to easily adjust the position of the spectacle frame body in the vertical and horizontal directions and the front-rear direction.

  In other words, the positional relationship between the ears and eyes varies from person to person, and in the case of a spectacle frame, it is actually fitted and the modern attached to the temple is adjusted to match the positional relationship of the user's ears and eyes. However, it is difficult to perform such adjustment work when the glasses are attached to the headphones, and even if the adjustments are made, if the wearing state of the headphones is not constant, the glasses are likely to be displaced. However, as in the present invention, by adjusting the angle adjusting member and the length adjusting member as appropriate, the position of the spectacle frame can be adjusted mainly in the vertical and horizontal directions by the angle adjusting member, and the length adjusting member Thus, the position adjustment in the front-rear direction can be mainly performed.

  And it is also possible to adjust with the angle adjustment member and the length adjustment member with the headphones attached, so that it is possible to adjust the position of the spectacle frame vertically, left and right and front and back to the optimum state Become.

  In addition, since the spectacle frame is detachably attached, it can be replaced with another spectacle frame, and even when the spectacle frame is replaced with another spectacle frame, the position can be easily adjusted accordingly.

  In addition, if a ball part is formed at one end of the angle adjusting member and is fitted in a ball receiving part provided on the support frame so as to be pivotably attached, the angular position can be widely varied in the vertical and horizontal directions. Since the outer surface of the ball portion is in pressure contact with the inner surface of the ball receiving portion, the ball portion is held by the frictional force. Therefore, if the angle adjusting member is manually rotated, the angle adjusting member can be stably held at the rotated angular position.

  Further, the angular position of the angle adjusting member is adjusted in a state in which the headphones are worn by restricting the rotation range so that the angle adjusting member is rotated toward the upper front side of the head by the opening peripheral edge of the ball receiving portion. In this case, when the adjustment is performed by groping, the rotation range is previously regulated to the upper front side of the head, and the adjustment work can be easily performed. Then, by restricting the rotation range to the upper front side of the head, it is possible to prevent the spectacle frame body from inadvertently moving out of the rotation range.

  Further, the length adjusting member slides either the front side member to which the spectacle frame body is detachably attached or the rear side member having one end portion rotatably attached to the support frame body with respect to the other in the front-rear direction. It is possible to adjust the length in the front-rear direction with a simple structure, and it is possible to reduce the weight by attaching the movable part and holding the both members in a predetermined positional relationship. It can be adjusted easily by groping.

  Hereinafter, embodiments according to the present invention will be described in detail. The embodiments described below are preferable specific examples for carrying out the present invention, and thus various technical limitations are made. However, the present invention is particularly limited in the following description. Unless otherwise specified, the present invention is not limited to these forms. In the following description, the vertical direction, the horizontal direction, and the front-rear direction indicate directions viewed from the user when headphones are worn on the user's head.

  FIG. 1 is an external perspective view of an embodiment according to the present invention. In the headphone 1, both end portions 20a and 20b of a support frame 2 that is curved so as to surround the back of the head are extended in a substantially straight line forward, and on the lower surfaces of the extended both ends 20a and 20b, Arm members 21a and 21b are respectively suspended downward. Bone conduction units 3a and 3b are attached to the lower ends of the arm members 21a and 21b, respectively.

  The bone conduction units 3a and 3b are rotatably attached to the arm members 21a and 21b. When the headphones 1 are mounted on the head as shown in FIG. 1, the bone conduction units 3a and 3b are placed on the front side of the ear. Adjust the position so that is pressed. When a signal is input to the bone conduction units 3a and 3b from an audio signal generator (not shown), the diaphragm of the bone conduction unit vibrates in accordance with the input signal and is conducted to the bone, thereby listening to the voice. be able to. Such a bone conduction unit may be a known hearing aid that listens to conversation or listens to music.

  Ball receiving portions 22a and 22b are formed on the upper surfaces of both end portions 20a and 20b above the bone conduction units 3a and 3b. The ball receiving portions 22a and 22b have lower end portions of the angle adjusting members 4a and 4b, respectively. The ball part formed in is fitted and rotatably mounted. The rear end portions of the length adjusting members 5a and 5b are attached to the upper end portions of the angle adjusting members 4a and 4b so as to be rotatable in the vertical direction. And the attachment parts 60a and 60b of the both ends of the spectacles frame 6 are attached to the front-end part of length adjustment member 5a and 5b so that attachment or detachment is possible.

  Since the angle adjusting members 4a and 4b are attached to the support frame 2 above the bone conduction units 3a and 3b, the spectacle frame 6 is supported above the bone conduction units 3a and 3b to be mounted in a stable state. Thus, the spectacle frame 6 can be stably mounted.

  FIG. 2 is an exploded perspective view of the angle adjusting member 4b and the length adjusting member 5b attached to one end 20b of the support frame 2. The angle adjusting member 4b has a ball portion 41b formed by spherically bulging the lower end portion of the shaft portion 40b. By fitting the ball portion 41b into the ball receiving portion 22b, the angle adjusting member 4b can be rotated. It is attached. A connecting portion 42b is formed at the upper end portion of the shaft portion 40b, and the connecting portion 42b is formed in a frame shape having a hinge structure.

  The ball receiving portion 22b is formed in a spherical shape so that the inner peripheral surface substantially coincides with the outer peripheral surface of the ball portion 41b, and is inclined as a whole so that the opening 23b that receives the ball portion 41b faces the front upper side of the head. It is formed in the state.

  The length adjusting member 5b includes a rod-shaped front member 50b and a rear member 51b. A hole 52b into which the rear member 51b is inserted is formed at one end of the front member 50b, and the other end of the rear member 51b is inserted into the hole 52b to be slidable. Attached to. In the portion of the front member 50b where the hole 52b is formed, an engagement hole 53b is formed in the side along the sliding direction of the rear member 51b. By engaging the engaging projections 54b formed on the side portions, the front member 50b and the rear member 51b are held in a predetermined positional relationship. The engagement hole 53b is formed with a wide portion and a narrow portion so that the engagement protrusion 54b is locked at a plurality of positions, and the length adjusting member 5b is changed depending on the position where the engagement protrusion 54b is locked. The overall length of the is adjusted.

  A magnet 55b is embedded in the other end of the front member 50b, and the eyeglass frame 6 is supported by a magnetic force by being in close contact with the magnet 61b embedded in the mounting portion 60b of the eyeglass frame 6. Can be done.

  A connecting portion 56b is formed at one end of the rear member 51b, and is formed in a pair of frame shapes having a hinge structure. Then, the rear side member 51b is inserted into the angle adjusting member 4b by inserting the connecting portion 42b of the angle adjusting member 4b between the pair of frames and inserting the shaft pin 57b into the shaft hole formed in each connecting portion. It is attached so that rotation is possible.

  FIG. 3 is a perspective view when the ball portion 41b of the angle adjusting member 4b is fitted into the ball receiving portion 22b. A notch 24b is formed in the upper portion of the ball receiving portion 22b, and the notch 24b is formed to have a width that allows the shaft portion 40b to be inserted by rotating the angle adjusting member 4b. In addition, when it is difficult to fit the ball 41b into the ball receiving portion 22b, it may be possible to easily fit the ball receiving portion 22b by making a cut.

  In the above description, the angle adjusting member 4b and the length adjusting member 5b have been described. However, the same applies to the angle adjusting member 4a and the length adjusting member 5a, and thus description thereof is omitted.

  FIG. 4 is a side view showing an adjustment state of the angular position by the angle adjusting member 4b. As shown in FIG. 4 (a), when the shaft portion 40b is tilted rearward, the length adjusting member 5b can be moved backward, and as shown in FIG. 4 (b), the shaft portion 40b. The length adjustment member 5b can be moved upward by setting the position to the upright position. Moreover, as shown in FIG.4 (c), when the axial part 40b is tilted to the front side, the length adjustment member 5b can be moved ahead. In this way, by rotating the shaft portion 40b in the front-rear direction, position adjustment in the up-down direction and the front-rear direction can be performed.

  FIG. 5 is a top view showing an adjustment state of the angular position by the angle adjusting member 4b. As shown in FIG. 5A, the position is adjusted in a direction away from the head by rotating the shaft portion 40b in the right direction. Moreover, as shown in FIG.5 (b), it can position-adjust in the direction close | similar to a head by turning to left direction. Thus, by rotating the shaft part 40b in the left-right direction, the distance between the angle adjusting members 4a and 4b can be adjusted along with the position adjustment in the left-right direction, and the contour of the eye-nose part on which the spectacle frame 6 is hung. It is possible to adjust appropriately according to the face width.

  When the ball portion 41b of the angle adjusting member 4b is fitted into the ball receiving portion 22b, the outer surface is in pressure contact with the inner surface of the ball receiving portion 22b, and the ball portion 41b is held by the frictional force. Therefore, if the angle adjusting member 4b is manually rotated, the angle position after the rotation can be held in a stable state.

  Further, the rotation range is regulated by the angle adjusting member 4b coming into contact with the peripheral edge of the opening 23b of the ball receiving portion 22b, and the rotation range is regulated toward the front upper side of the head within a predetermined angle range. It becomes like this.

  FIG. 6 is a top view showing a state in which the headphones 1 are mounted on the head. In FIG. 6A, since both end portions 20a and 20b of the support frame 2 are mounted substantially along the front-rear direction on the side surface of the head, the angle adjusting members 4a and 4b are also at angular positions along the front-rear direction. The eyeglass frame 6 is optimally mounted by adjusting the lengths of the length adjusting members 5a and 5b as appropriate and rotating the angle adjusting members 4a and 4b in the front-rear direction for fine adjustment. Can do. In FIG. 6 (b), since both end portions 20a and 20b are opened to the left and right on the side of the head, the shaft portions of the angle adjusting members 4a and 4b are rotated in the left-right direction along the front-rear direction. Then, the angle position is adjusted, the lengths of the length adjustment members 5a and 5b are adjusted as appropriate, and the angle adjustment members 4a and 4b are rotated in the front-rear direction to make fine adjustments. Can be installed in a state.

  Since the adjustment work of the angle adjustment member and the length adjustment member as described above can be easily performed with the headphones 1 mounted on the head, the adjustment can be performed while checking the wearing state of the spectacle frame 6. It is possible to set an optimum state according to the contour of the face.

  Moreover, since the spectacle frame 6 is detachably attached, it can be easily replaced with another spectacle frame. As shown in FIG. 7, the attaching parts 60a and 60b of the spectacle frame 6 are removed from the magnets 55a and 55b embedded in the ends of the length adjusting members 5a and 5b, and the attaching part of another spectacle frame is attached. What should I do? Even in this case, the replacement work can be performed with the headphone 1 mounted on the head, and the adjustment work can be performed according to the spectacle frame attached after the replacement, and can be easily replaced with another spectacle frame. It becomes possible.

  Further, when the spectacle frame 6 is not attached, as shown in FIG. 8, the angle adjusting members 4a and 4b are rotated to the rear side, and the notches 24a and 24b formed in the ball receiving portions 22a and 22b. By inserting the shaft portions 40a and 40b into the housing and storing the angle adjusting member and the length adjusting member in a state of being tilted along both end portions of the support frame 2, troubles arise in handling the headphones. There is nothing.

  In the example described above, the bone conduction unit is used as the headphone unit, but a headphone unit using a speaker unit can also be used. As shown in FIG. 9, a headphone 1 ′ having speaker units 3a ′ and 3b ′ attached to both ends of a support frame 2 ′ attached to the head, and speaker units 3a ′ and 3b at both ends of the support frame 2 ′. By forming the ball receiving portions 22a ′ and 22b ′ above 3b ′ and attaching the angle adjusting member and the length adjusting member described above, a headphone with the spectacle frame 6 attached thereto can be realized. In this example, when the angle adjusting member and the length adjusting member are stored, they may be stored in a standing state along the support frame.

  When the angle adjusting member is pivotably attached to the support frame, as described above, other pivotable attachment structures such as a universal joint structure and a bellows structure may be used in addition to the ball joint structure, which is particularly limited. Not. Similarly, when the length adjusting member is rotatably attached to the angle adjusting member, a rotatable structure other than the hinge structure described above may be used.

It is a whole perspective view regarding the embodiment concerning the present invention. It is a disassembled perspective view of an angle adjustment member and a length adjustment member.
