Description

  The present invention relates to an earphone that can be worn along the outer periphery of an ear, and more particularly to a headphone that can keep the entire ear warm in a cold season.

  Conventionally, with regard to headphones, a headphone that wraps a headband above the head, a headphone that wraps a headband behind the head, or an ear hook member called a hanger is attached to the outer periphery of the ear. There are a wide variety of headphones such as headphones that are worn by the user (hereinafter referred to as “ear headphones”).

  Among these, there are headphones as described in the following Patent Document 1 and the like as the headphones with a heat retaining function that can keep the ear warm in the cold season.

The headphone with a heat retaining function described in Patent Document 1 is a headband type headphone, and a heat retaining member that covers the entire ear is attached to the tip portion of the headband, and the entire ear is sandwiched by the sandwiching force of the headband. Can be kept warm.
Patent Publication 2004-511991

  However, this headphone with a heat retaining function covers the ear with a heat retaining member with the sandwiching force of the headband, and therefore cannot be applied to a headphone with no headband. For this reason, if the heat retaining member is attached to the ear hook member corresponding to the headband in order to attach the heat retaining member to the earphone, the heat retaining member is sandwiched between the ear and the head, The headphones are dropped due to bending.

  Therefore, the present invention has been made paying attention to the above-mentioned problems, and it is possible to similarly attach a heat retaining member even to an earphone with no headband, and to prevent the ear from being bent when worn. Thus, an object of the present invention is to provide an earphone that can be securely worn.

  That is, in order to solve the above problems, the present invention includes a housing with a speaker attached thereto, and an ear hook member that is hung along the outer peripheral portion of the back of the ear so that the housing is positioned on the front side of the ear. In such a headphone, a detachable member having a heat retaining member covering the entire ear is detachably attached to the housing.

  In this way, since the heat retaining member is attached to the housing located on the front side of the ear, the ear is bent as in the case of attaching the heat retaining member to the ear hook member between the ear and the head. This eliminates the loss of headphones. In addition, there is no sense of incongruity behind the ear when the heat retaining member is attached. Furthermore, since such a heat retaining member is detachably attached to the housing, the heat retaining member can be attached in the cold season, and the heat retaining member can be detached and used in the warm season.

  Moreover, in such an invention, the detachable member is formed of a cover body that covers the back side of the speaker.

  If comprised in this way, since the sound output from a speaker can be absorbed with a cover body or a heat retention member, the sound leakage to the exterior can be prevented now.

  Further, as such a heat retaining member, a material or a structure that allows a cord connected to a speaker to pass inside is used.

  Usually, when a heat retaining member is put on the earphone, the cord of the headphone is pressed against the face by the heat retaining member, which causes a sense of incongruity at that portion. However, if such a material or structure that allows the cord to pass inside the heat retaining member is adopted, the cord will not be pressed against the face, and an uncomfortable feeling will not occur.

  In addition, when the heat retaining member is mounted, the rotational moment is applied to the ear hooking member in the ear mounting direction depending on the position of the center of gravity.

  Generally, the ear hook member is attached by rotating along the outer periphery of the ear, but when attaching the heat retaining member, if a rotational moment is generated in the direction opposite to the wearing direction, the headphones fall off from the ear. End up. However, if the position of the center of gravity is set so that the rotational moment acts in the wearing direction in this way, the headphone can be firmly fixed to the ear by the rotational moment.

  In the present invention, in a headphone comprising a housing to which a speaker is attached and an ear hook member that is hung along the outer periphery of the ear so that the housing is positioned on the front side of the ear, a heat retaining member that covers the entire ear is provided. Since the attachment / detachment member is detachably attached to the housing, the ear is not bent as in the case of attaching the heat retaining member to the ear hook member between the ear and the head. The headphones can be prevented from falling off. In addition, there is no sense of incongruity behind the ear when the heat retaining member is attached. Furthermore, since such a heat retaining member can be removed, the heat retaining member can be attached during the cold season, and the heat retaining member can be removed during the warm season.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an exploded perspective view of the headphone 1 in the present embodiment, and FIG. 2 shows a state in which the headphone 1 is assembled. FIG. 3 is a cross-sectional view taken along the line AA in FIG. FIG. 4 shows the wearing state of the headphones 1, and shows the usage state in winter (FIG. 4 (a)) and the usage state in summer (FIG. 4 (b)), respectively.

  A headphone 1 according to the present embodiment is an earphone 1 that is generally well-known, and includes a plug 20 (see FIG. 4) to be inserted into an audio output device such as a CD player or an MD player, and the plug 20. And a pair of speaker units 10a connected to the distal end side of the cord 21. 1 to 4 show a right-ear speaker unit 10a. Each speaker unit 10a includes a hanger-like ear hook member 3 hung along the outer periphery of the listener's ear, a housing 4 connected to the base end 30 side of the ear hook member 3, and the housing 4 is provided with a speaker 7 that outputs sound and a cover body 5 that is detachably attached to the opposite side of the speaker 4 in the housing 4. In this embodiment, the cover body 5 is kept warm. The member 6 is attached integrally. Then, as shown in FIG. 4 (a), a cover body 5 with a heat retaining member 6 is attached in a cold season such as winter, and in a warm season such as summer as shown in FIG. 4 (b). The cover body 5 that does not have the heat retaining member 6 is attached.

  As the plug 20 used for the headphone 1, when a stereo sound source is reproduced, for example, a plug having three electrode portions is used. The end portion of the cord 21 extending from the plug 20 is connected to the speaker 7 of one of the pair of left and right speaker units 10a (first speaker unit 10a for the right ear in the present embodiment), and The first speaker unit 10a is connected to the other second speaker unit 10a via the second cord 21a. The second cord 21a circulates around the back of the listener's neck, and a cable cover 21b such as a non-woven fabric is attached to the surface of the second cord 21a to improve the feeling of contact with the neck.

  The housing 4 constituting the left and right speaker units 10a is formed of a relatively hard synthetic resin or the like, and has a substantially circular shape having a convex portion 40 at the center. A speaker 7 is attached inside the housing 4. In addition, with the speaker 7 attached, an ear bud 8 that wraps the housing 4 and the speaker 7 is attached. The ear bud 8 is attached so as to wind up a flange portion 41 which is a flange-shaped outer peripheral portion of the housing 4.

  The left and right housings 4 are attached with ear hook members 3 that are hung along the outer periphery of the ears. The ear hook member 3 is formed in a curved shape by a relatively supple resin or the like, and is formed by a resin such as polypropylene (PP), polybutylene terephthalate (PBT), or polyacetal (POM), for example. And the base end 30 side of this ear hook member 3 is attached to the convex part 40 of the housing 4 so that rotation is possible, and the free end 31 side which is the other end side is located in the back side of an ear | edge. When attaching the ear hook member 3 to the outer peripheral portion behind the ear, first, the housing 4 is pressed against the center of the ear for positioning, and the ear hook member 3 is applied to the rear portion of the ear while bending the ear. Then, the housing 4 is rotated in the left rotation direction for the right ear, and in the right rotation direction for the left ear, that is, in the mounting direction, the ear hooking member 3 is positioned at an appropriate position.

  Then, the cover body 5 having the heat retaining member 6 is attached to the housing 4. Hereinafter, the attachment structure of the cover body 5 having the heat retaining member 6 will be described. Since the right ear housing 4 and the left ear housing 4 have the same structure, the following description will be made using one housing 4 and the cover body 5.

  As described above, the housing 4 has a circular shape having the convex portion 40 and the flange portion 41, and the speaker 7 is attached to the concave portion 40 c (see FIG. 3) formed on the back side of the convex portion 40. The speaker 7 is engaged with the concave portion 40c by engagement or a claw portion 70 provided on the outer peripheral portion of the speaker 7 or the like. Further, a cord 21 is connected to the speaker 7, and the cord 21 can be extended to the outside via a cord insertion notch 40 a provided on the side surface of the convex portion 40 of the housing 4.

  In addition to the cord insertion notch 40a, a plurality of notches 40b are provided on the side surface of the convex portion 40 of the housing 4. Then, a claw portion 50 is provided at the position of the cover body 5 corresponding to the notch hole 40b, and the cover body 5 is detachably attached to the housing 4 by engaging the notch hole 40b and the cover body 5.

  The cover body 5 has a curved shape so as to cover the back side of the speaker 7, and a heat retaining member 6 for retaining the entire ear is attached to the outside of the curved portion. The heat retaining member 6 has a size that covers the outer periphery of the ear, and is made of a material that can come into contact with the head, cheeks, and the like in the vicinity of the outer periphery of the ear. As such a material, for example, a material that is relatively light, soft, and has heat retaining properties, such as an animal fur or a fleece having a long bristle, is used. The cord 21 from the speaker 7 is stored in the fur hair gap or the like so that the cord 21 is not pressed against the cheek.

  Such a cover body 5 with the heat retaining member 6 is used in a relatively cold season such as winter. In addition, in a relatively hot season such as summer, a cover body 5 that does not have the heat retaining member 6 is separately prepared so that it can be attached. By doing so, the entire ear can be kept warm in the cold season, and the cover body 5 without the heat retaining member 6 can be attached by removing the cover body 5 in the hot season.

  As shown in FIG. 4A, the cover body 5 with the heat retaining member 6 is set to a gravity center position G that gives a rotational moment in the direction in which the headphones 1 are attached while being attached to the housing 4. Specifically, when the base end 30, which is a connection portion between the ear hook member 3 and the housing 4, is used as a fulcrum, the center of gravity is set on the side closer to the free end 31 of the ear hook member 3. In this way, even when the cover body 5 to which the heat retaining member 6 is attached is mounted, a rotational moment acts on the free end 31 side with the base end 30 of the ear hook member 3 as a fulcrum, and the ear hook member 3 Can be firmly fixed to the outer periphery of the back of the ear. As a method of setting the center of gravity position G, a method of setting the center of gravity position G by attaching a weight to the cover body 5 or a method of setting the center of gravity position G by the weight of the heat retaining member 6 can be considered.

  As described above, the embodiment includes the housing 4 to which the speaker 7 is attached, and the ear hooking member 3 that is hung along the outer periphery of the back of the ear so that the housing 4 is positioned on the front side of the ear. In the headphone 1, the cover body 5 having the heat retaining member 6 covering the entire ear is detachably attached to the housing 4. Therefore, the entire ear can be simply attached to the housing 4 by attaching the cover body 5 having the heat retaining member 6. It becomes possible to keep warm. Moreover, since the heat retaining member 6 is attached to the housing 4 mounted on the front side of the ear, the ear is bent as in the case where the heat retaining member 6 is attached to the ear hooking member 3 that circulates behind the ear. It is possible to prevent problems such as dropping the headphones 1 or causing a sense of incongruity when a large foreign object is caught between the ear and the head. Furthermore, since the heat retaining member 6 can be attached to and detached from the housing 4, the heat retaining member 6 can be attached in the cold season, and the heat retaining member 6 can be detached and used in the warm season.

  Moreover, in the said embodiment, since the detachable member was comprised with the cover body 5 which covers the back surface side of the speaker 7, the sound output from the speaker 7 can be absorbed with the cover body 5 or the heat retaining member 6, It is possible to prevent sound leakage to the outside and prevent inconvenience to others.

  Furthermore, as such a heat retaining member 6, a fur or the like that allows the cord 21 connected to the speaker 7 to pass inside is adopted, so that the cord 21 is not pressed against the cheek, and the user feels uncomfortable when wearing it. Can be eliminated.

  In addition, when the proximal end 30 of the ear hook member 3 is used as a fulcrum, the center of gravity position G is set so that the rotational moment is applied to the side on which the ear hook member 3 is attached to the ear. 1 can be firmly fixed to the ear.

  In addition, this invention is not limited to the said embodiment, It can implement in a various aspect.

  For example, in the above embodiment, the cutout hole 40b is provided in the side surface portion of the convex portion 40, and the claw portion 50 of the cover body 5 is engaged with the cutout hole 40b. A notch hole or the like may be provided on the upper surface of 40 and the claw portion of the cover body 5 may be engaged with the notch hole.

  In the above-described embodiment, an example in which animal fur or fleece is used as the heat retaining member 6 has been described. However, the present invention is not limited to this, and it is possible to shield the entire ear from outside air and keep the entire ear warm. Any material may be used. However, if a relatively hard material is used, the cord 21 may be pressed against the cheek by the heat retaining member 6, so that the cord 21 is retracted from the cheek by providing a cord insertion notch or the like on the heat retaining member 6. It is good to do so.

  Furthermore, in the above embodiment, the heat retaining member 6 is attached to the housing 4 via the cover body 5, but this is not limiting, and for example, the heat retaining member 6 may be attached to the housing 4 via engagement means such as a hook. Also good.
