Description

  The present invention relates to a headphone device, and relates to a technique for improving wearability and improving a feeling of use at the time of wearing.

  2. Description of the Related Art Conventionally, there is a headphone device in which a driver unit is held at both ends of an elastic headband, and the headband is attached to the head in a state where the headband goes around the back of the head.

  FIG. 6 shows an example of the headphone device as described above. The headphone device a includes driver units b and b (only one is shown in the figure) and a headband c that holds the driver units b and b at both ends. The driver units b and b contain appropriate electroacoustic conversion means for converting electrical signals into acoustic vibrations.

  The headband c is made of a substantially belt-like elastic material, for example, a metal spring member, and driver units b and b are held in a suspended manner at both ends thereof.

  Accordingly, the headphone device a slightly adjusts the position of the driver units b and b and the ear so as to slightly widen the distance between both ends of the headband c from the back head e side to the head d, and the ear shell f. , F (only one is shown in the figure) and the driver units b and b are mounted in pressure contact with each other. At this time, the headphone device a is positioned so that a part of both ends of the headband c wraps around the upper part of the earshells f and f from the back side, and the driver units b and b are connected to the earshell f by the elasticity of the headband c. , F so that the earshells f and f are loosely sandwiched between the headbands c and c and the driver units b and b, respectively, and at the same time, the middle part of the headband c In this state, the head is in contact with or over the collar, and the mounting state on the head d is maintained.

  By the way, in the conventional headphone device a, as described above, when the headphone device a is attached, the driver units b and b have the elasticity of the headband c and the driver units b and b and the headband c. The weight is supported and held by both ends sandwiching the earshells f and f, but the headband c is in a state where the middle part is in contact with or rides on the occipital region e, neck or collar on the occipital region e side. There is no structure to positively support the weight.

  Therefore, for example, when the headband c touches the collar of clothes or the like due to the movement of the head of the user of the headphone device a and the stress is applied to the headband c, the position of the headband c easily changes. As the headband c moves, the positional relationship between the driver units b and b and the earshells f and f changes, and the volume and quality of the sound heard from the left and right driver units b and b change. There has been a problem that the ear shells f and f are unnecessarily pressed and the user feels uncomfortable.

  Therefore, as a countermeasure to the above problem, a hinge or the like is interposed between the driver units b and b and the headband c so that the change in the position of the headband c as described above is not transmitted to the driver units b and b. It is possible to do.

  However, the headphone device a requires that the driver units b and b are brought into pressure contact with the ear shells f and f with a certain amount of pressure, and as described above, the hinges are connected between the driver units b and b and the headband c. If the structure is interposed between them, the force due to the elasticity of the headband c is not easily transmitted to the driver units b and b, and the force that presses the driver units b and b against the ear shells f and f is weakened. was there. Accordingly, the relationship between the driver units b, b and the ear shells f, f is not changed by the change in the position of the headband c, and the driver units b, b are pressed against the ear shells f, f with a certain pressure. It has become difficult to achieve a balance with securing the power to make it difficult to solve the above problems.

  Further, like the headphone device a, the headband c is simply composed of a substantially elastic material such as a metal spring member, and the mounting posture of the headphone device a almost depends only on the elasticity of the headband c. If the structure is such that the elasticity of the headband c is inevitably increased, the driver units b and b are strongly pressed against the earshells f and f, so that the headphone device a is stable. Ensuring the wearing state and reducing the burden on the head d and ear shells f and f when wearing the headphone device a for all shapes of heads and ear shells with great individual differences. It was difficult to achieve both.

  Further, in a structure in which the driver units b and b and both ends of the headband c sandwich the earshells f and f as in the headphone device a, the driver units b and b and the headband c when the headphone device a is worn. Since there is no mechanism for ensuring the clearance between both ends of the head, the distance between the driver units b, b and both ends of the headband c is set larger than the ear shells f, f before mounting. It is necessary to adjust the distance between the driver units b and b and both ends of the headband c by groping, which is troublesome to mount.

In order to solve the above-described problem, the headphone device of the present invention is connected to a driver unit that is brought into contact with the front side portion of the ear shell, a connecting portion having one end attached to the driver unit, and the other end of the connecting portion. And the rear side of the ear shell interposed between the back side portion of the ear shell and the head facing the back side portion of the ear shell from the position corresponding to the upper portion of the ear shell and bent by the bent portion. A headphone device having a member adapted to the shape of the root portion, and having an ear hook portion in which the interposed member, the bent portion, and the connecting portion are integrally formed of synthetic resin, when the headphone device is mounted In addition, when the intervening member comes into contact with the rear root portion of the ear shell, it is shaped so as to come into contact with the rear root portion of the ear shell, and the bent ear hook portion returns. the force, the auricle by the member and the driver unit interposed Sexually it is obtained so as to sandwich while pressing from the side.

In addition, the headphone device of the present invention is formed through a bent portion at least one end of both ends of an arc-shaped headband that is formed of a synthetic resin and whose both ends are elastically movable toward and away from each other. A headphone device in which a connecting portion bent outward is integrally provided, a driver unit is attached to a tip portion of the connecting portion, and the driver unit can be elastically moved to and away from the headband by the bent portion. When the headphone device is attached, the headband is held by being pressed from the side by the elasticity of the headband, and the earshell is elastically pressed by the vicinity of one end of the headband and the driver unit. comprising a member headband adapted to the shape of the side root portion after the auricle during the head facing the rear portion of the rear portion and the concha of the auricle while the sandwich, the moiety At the time of contact with the side root portion after the auricle, in which is shaped so as to abut the side root portion after the auricle.

According to the present invention, since the ear shell is elastically sandwiched between the driver unit and the member adapted to the shape of the rear root portion of the ear shell, the positional displacement of the driver unit when the headphone device is worn is prevented. In addition to preventing, it is possible to obtain a light wearing feeling.

  The best mode of the headphone device of the present invention will be described with reference to FIGS.

  The headphone device 1 includes a pair of driver units 2 and 2 and a headband 3 that supports the driver units 2 and 2 at both ends thereof.

  In the following description, when describing the front, rear, left and right directions, the lower and upper directions in FIG. 1 are the front and rear, respectively, the left and right are the right and left, respectively, and the upper and lower in FIG. Use the vertical direction as it is.

  Each of the driver units 2 and 2 includes a housing portion 4 having a substantially bowl shape and an ear pad portion 5 having a substantially dish shape attached to the housing portion 4, and an electric signal is acoustically vibrated inside the housing portions 4 and 4. A speaker or the like (not shown), which is a means for converting to a sound, is accommodated. A cord 6 is connected to the speaker of one driver unit 2 from the outside, and another cord (not shown) is connected to the speaker in the other driver unit 2 through the inside of the headband 3.

  The headband 3 includes a main portion 7 having a flat oval shape in cross section, a left end portion 7a and a right end portion 7b positioned in front of the main portion 7, and a driver following the left end portion 7a and the right end portion 7b. The unit connecting portions 8 and 8 are integrally formed of a flexible and elastic material such as polypropylene.

  Further, as shown in FIG. 4, the main portion 7 of the headband 3 has a curved shape so as to match the shape of a general human head 9, particularly the back of the head 10. It is designed to have an approximate Ω shape.

  Further, the left end portion 7a and the right end portion 7b of the headband 3 are formed so as to be curved upward as a whole, and have a shape substantially along the upper side of the ear shells 11 and 11.

  The left end 7a and the right end 7b of the headband 3 are formed with slits 12 and 12 that open downward for attaching a latching body to be described later.

  The driver unit connecting portions 8 and 8 are folded back diagonally downward from the front ends of the left end portion 7b and the right end portion 7b and displaced rearward, and the distance from the headband 3 increases as it goes to the front end. In other words, it is formed in such a shape that it goes to the left and right as it goes to the tip, and the tip is close to the front side of the driver unit 2, 2 at the housing part 4, 4. The driver units 2 and 2 are supported in such a state that the contact surfaces of the earpad portions 5 and 5 with the ear shells 11 and 11 are obliquely rearward and upward.

  The latching bodies 13 and 13 are formed by integrally forming support parts 14 and 14 which are the first half part and auxiliary support parts 15 and 15 which are the second half part. 11 is hooked on the base of 11 from above and behind, and functions as a member that supports the weight of the headphone device 1 and maintains a stable posture. In addition, the above-mentioned hooks 13 and 13 are used to absorb the individual differences in the shape of the earshells 11 and 11 and the base part thereof, and to reduce the burden when the headphone device 1 is worn. It is made of a softer flexible material such as an elastomer.

  The support portions 14, 14 have a ridge-like shape with rounded corners, abut on the upper root portions 11 a, 11 a of the ear shells 11, 11, and the headphone device 1 excluding the main portion 7 of the headband 3. It is the part that supports most of the weight.

  Further, the auxiliary support portions 15 and 15 come into contact with the rear root portions 11b and 11b of the ear shell, and the main portion 7 of the headband 3 hangs down with the front ends of the support portions 14 and 14 as fulcrums due to its weight. In order to make it easy to bend as a whole, hollow holes 15a and 15a are provided to leave the edges, so that the auxiliary support portions 15 and 15 are formed as shown in FIG. As shown by a broken line, it becomes easy to bend, and it can come into contact with the rear root portions 11b and 11b of the ear shell more softly than the other portions of the hooks 13 and 13. The auxiliary support portions 15 and 15 have lower end portions 15b and 15b that are displaced to the right or left of the other portions, that is, the head 9 side, so that the headphone device 1 is stably attached. Is easier to maintain.

  And the upper end of the latching bodies 13 and 13 makes thin plate shape, and as shown in FIG. 3, the fitting protrusions 16 and 16 for fitting to the slits 12 and 12 of the headband 3 are shown. Are integrally formed.

  As shown in FIGS. 1 and 3, the latching bodies 13, 13 having the structure described above are inserted into the slits 12, 12 and the left end of the headband 3. It fixes to the part 7a and the right end part 7b, respectively. Then, the hooks 13 and 13 extend along the shapes of the left end portion 7a and the right end portion 7b of the headband 3, and the earshell hooking portions 14 and 14 and the auxiliary support portions 15 and 15 are respectively As it goes downward, it is in a state of being suspended to the right or left. And the lower end parts 15b and 15b of the auxiliary | assistant support parts 15 and 15 respectively form the part protruded most rightward or leftward.

  Accordingly, the headphone device 1 is mounted on the head 9 as follows.

  That is, as shown in FIG. 4, the headphone device 1 grips a part of the driver units 2, 2, and widens the distance between the left end portion 7 a and the right end portion 7 b of the headband 3 in the left-right direction. From the left end 7a of the headband 3 so that the ear shells 11 and 11 are placed in the space between the ear pad parts 5 and 5 and the hooking bodies 13 and 13. The right end portion 7b is moved forward through the position above the heel of the ear shells 11 and 11 as a whole.

  When the auxiliary support portions 15 and 15 of the latching bodies 13 and 13 come into contact with the rear root portions 11b and 11b of the ear shell, the support portions 14 and 14 are brought into contact with the upper root portions 11a and 11a of the ear shell. Push down the whole area down to make contact, and release the hand. Then, the earpad parts 5 and 5 of the driver units 2 and 2 are pressed against the earshells 11 and 11 from the side by the force of returning the bent headband 3 to the original state, and at the same time, the earpad parts 5 and 5 and the earshells 11 and 11, and the headphone device 1 is completely attached.

  When the headphone device 1 is attached, the driver units 2 and 2 are brought into contact with the ear shells 11 and 11 of the earpad parts 5 and 5 by the driver unit connecting parts 8 and 8 of the headband 3 as described above. Since the surface is supported diagonally rearward and upward, the headband 3 and the driver unit connecting portions 8 and 8 can be obtained simply by gripping the driver units 2 and 2 and pulling them lightly to the left and right as shown in FIG. The folded portion becomes a fulcrum, and the interval θ between the earpad parts 5 and 5 and the auxiliary support parts 15 and 15 is increased, and the earshells 11 and 11 can be easily inserted therebetween.

  Moreover, although the latching bodies 13 and 13 protrude in the left or right direction rather than the left end part 7a and the right end part 7b of the headband 3, since it is formed with the material which has flexibility, it bends easily. It does not become a resistance at the time of wearing.

  Furthermore, since the auxiliary support portions 15 and 15 of the latching bodies 13 and 13 are provided with the hollow holes 15a and 15a, the peripheral portions of the hollow holes 15a and 15a can be bent, In combination with the flexibility of the material forming the auxiliary support portions 15, 15, it adapts to the shape of the rear root portion 11 b, 11 b of the ear shell having a large individual difference. The burden on the rear root portions 11b and 11b is reduced.
