Description

  The present invention relates to headphones.

  Various types of headphones are known. For example, there is an “ear covering type” in which the headphone unit covers the user's ear when worn, and an “ear mounting type” in which the headphone unit is placed on the user's ear. In both the ear covering type and the ear mounting type, the headphone unit is fixed to both ends of the band member. This band member is a member that draws an arc in the longitudinal direction, and has a spring property. When the headphones are worn, the distance between the end portions of the band member is increased. When the headphone unit is applied to the auricle or its periphery, a lateral pressure is applied to the user's auricle and its peripheral part by the restoring force of the band member. With this lateral pressure, the headphone unit is held around or on the user's pinna.

  The ear covering type and the ear mounting type are further roughly classified according to the position of the band member at the time of wearing. For example, a type in which the band member straddles the user's head, a type in which the band member is hung on the user's neck (back band type), and the like are known.

  Since there are individual differences in the shape and dimensions of the user's head and ears, the magnitude of the lateral pressure suitable for wearing varies depending on the user. Since the side pressure is based on the spring property of the band member, for example, if the user's head is too small relative to the band member, the side pressure will be too weak. If the lateral pressure is weak, it may cause sound leakage or slipping. Moreover, when a user's head is too big with respect to a band member, a side pressure will be too strong. If the side pressure is too strong, the user's auricle and the surrounding area are compressed, and the feeling of use becomes uncomfortable.

  A headphone that solves the feeling of use of the headphone as described above is known (see, for example, Patent Document 1). However, it is difficult for the headphones of Patent Document 1 to maintain a state in which a favorable feeling of use is obtained in response to individual differences among users. Therefore, the applicant of the present application has invented a headphone that can improve the feeling of wearing regardless of individual differences and that prevents sound leakage and a decrease in sensitivity, and has filed an application earlier (see Patent Document 2).

JP-A-11-27778 JP 2008-283281 A

  The headphones of Patent Literature 2 can improve the wearing feeling corresponding to individual differences among users and can prevent sound leakage. However, since the band member is fixed at the central portion of the housing, the side pressure is applied from one point of the central portion. If it does so, a user's wearing feeling will feel that a headphone unit is strongly pressed from one point, and will reduce a wearing feeling. Patent Document 2 has a complicated structure and a large number of parts. Therefore, the headphones of Patent Document 2 have a lot of room for improvement.

  The present invention has been made in view of the above problems, and provides a headphone that can be comfortably worn even when worn for a long time regardless of individual differences among users and can be configured with a small number of components. With the goal.

  The present invention is a headphone in which a headphone unit is fixed to an end portion of a band member, and the headphone unit includes a baffle to which a driver unit is fixed, an ear pad to be fixed to the baffle, and the baffle to which the headphone unit is fixed. The frame has a circular portion and a band fixing portion, and the band fixing portion protrudes from the outer peripheral side surface of the circular portion to the outside in the diameter direction of the circular portion. Thus, the most main feature is that the end portion of the band member is fixed to the band fixing portion.

  According to the present invention, a comfortable wearing feeling can be obtained even when worn for a long time regardless of individual differences among users, and it can be configured with a small number of parts.

It is a perspective view which shows the example of the whole shape of the headphones which concern on this invention. It is a disassembled perspective view which shows the example of a detailed structure of the said headphones. It is sectional drawing which shows the example of the one part cross-sectional shape of the said headphones. It is a figure which shows the example of the use condition of the headphones which concern on this invention.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the overall shape of a headphone 100 according to the present embodiment.

  As shown in FIG. 1, the headphone 100 includes a headphone unit 1 and a band member 2. The headphone unit 1 is fixed to both ends of the band member 2. The headphone 100 that is not worn by the user is in a state in which the ends of the headphone unit 1 are close to each other following the shape of the band member 2. In the state worn by the user, the headphones 100 are in a state where the distance between the end portions of the band member 2 is widened. In other words, the distance between the headphone units 1 is increased.

  The band member 2 is a member formed of a metal or resin having spring properties. The band member 2 has an outer shape that draws an arc in the longitudinal direction. When wearing the headphones 100, the user holds the headphone unit 1 and widens the arc of the band member 2. Then, a restoring force that tries to bring the end portions closer to each other by the spring property of the band member 2 acts on the headphone unit 1. That is, the headphone unit 1 at the time of wearing is urged by a force toward the inside of the arc formed by the band member 2. This force exerts a lateral pressure on the user's temporal region. The headphone unit 1 is held at a predetermined position by this lateral pressure.

  Next, a detailed configuration of the headphone unit 1 will be described with reference to FIG. FIG. 2 is an exploded perspective view mainly showing a detailed configuration of the headphone unit 1 on one side. As already described, the headphone 100 includes the headphone unit 1 and the band member 2. As shown in FIG. 2, the headphone unit 1 includes a frame 10, a baffle 20, a driver unit 30, an ear pad 40, and a frame cap 50.

  The frame 10 is a member constituting a housing (housing) of the headphone unit 1 and is formed of a rigid material. The material used for the frame 10 is, for example, a hard resin material.

  The frame 10 is integrally formed with two greatly different shapes. The frame 10 includes a circular portion 11 and a band fixing portion 12. The circular portion 11 has a circular dish shape having a predetermined depth and has a shape such that the bottom portion is missing. In other words, the circular portion 11 has a shape obtained by dividing a doughnut-shaped member in the thickness direction and pulling out one inside.

  When the frame 10 is captured as a dish-like member, the inner space extends from the outer peripheral edge to the bottom of the frame 10. Further, when the frame 10 is regarded as a divided donut-shaped member, similarly, a space formed by pulling out the divided surface side becomes an internal space. In this inner space, the driver unit 30 and the baffle 20 are arranged and fixed. Therefore, the depth of the inner space corresponds to the dimension in which the driver unit 30 and the baffle 20 are disposed.

  The band fixing portion 12 has a shape such that a part of the outer peripheral side surface of the circular portion 11 protrudes outward in the diameter direction of the outer periphery of the circular portion 11. The band fixing portion 12 has a depth at which the end of the band member 2 can be disposed. The band fixing portion 12 and the circular portion 11 have no seam, and the circular portion 11 and the band fixing portion 12 are integrally formed as a frame 10.

  The end of the band member 2 is in a state in which a member connected to the spring member of the band member 2 protrudes from the outer skin of the band member 2. This protruding portion is the frame coupling portion 3. The frame coupling portion 3 may be the same metal as the spring member, or may be a rigid member coupled to the spring member.

  The band fixing portion 12 surrounds the frame coupling portion 3 from three directions. A band fixing member 13 is fitted to the open surface of the band fixing portion 12. That is, the frame coupling portion 3 is coupled to the frame 10 by being surrounded on all sides by the band fixing portion 12 and the band fixing member 13.

  In other words, the frame coupling portion 3, which is the end portion of the band member 2, is sandwiched between the band fixing portion 12 and the band fixing member 13 and cannot be removed from the band fixing portion 12. As a result, the band member 2 and the frame 10 are coupled. Thus, the frame 10 and the band member 2 are fixed.

  The baffle 20 is a member having a disk-like outer shape, and includes an outer edge portion 21 and an inclined portion 22. The outer edge portion 21 is an outer peripheral edge portion formed by a plane in the diameter direction of the baffle 20. The inclined portion 22 is a portion inclined with respect to the outer edge portion 21, and is continuous with the outer edge portion 21. In other words, the inclined portion 22 is inclined with respect to an axis orthogonal to the central axis of the outer edge portion 21 that is the outer peripheral portion of the baffle 20.

  A large number of sound holes (through holes) are formed in the inclined portion 22. As shown in FIG. 3, the driver unit 30 is fixed to the inclined portion 22 of the baffle 20 on the frame 10 side. The diaphragm which is a sound emitting part of the driver unit 30 faces the inclined part 22. Therefore, the sound output from the driver unit 30 passes through the sound hole of the inclined portion 22 and is output to the outside.

  The driver unit 30 includes a diaphragm (not shown), a magnetic circuit that drives the diaphragm, and wiring that applies an electrical signal to the magnetic circuit. The driver unit 30 is a sound emitting unit, and is a electroacoustic transducer in which a diaphragm is driven in accordance with an electric signal and sound is output by driving the diaphragm.

  The ear pad 40 is made of a member having a cushioning property that can be deformed by external pressure. The ear pad 40 is formed by, for example, wrapping urethane foam or the like with an exterior film made of synthetic leather. The ear pad 40 is a member that is fixed to the outer edge portion 21 of the baffle 20 and is pressed against the user's auricle or auricle periphery when worn. For example, an adhesive is used to fix the ear pad 40 to the baffle 20.

  The frame cap 50 is a member that closes the hole at the bottom of the frame 10. The hole at the bottom of the frame 10 is provided to facilitate work when the baffle 20 is fixed to the frame 10 or when the driver unit 30 is adjusted. The frame cap 50 is attached in order to prevent foreign matter from entering the inside of the frame 10 in the final manufacturing process.

  Next, the configuration and effects of the headphones 100 will be further described. FIG. 3 is a cross-sectional view showing a partial cross-sectional shape of the headphone 100. The cross-sectional view of FIG. 3 is a longitudinal cross-sectional view of the headphone unit 1 on one side and a part of the band member 2 coupled thereto, in which the frame 10 and the baffle 20 are cut in the radial direction.

  As shown in FIG. 3, the baffle 20 to which the driver unit 30 is fixed is fixed so that the outer edge portion 21 and the outer peripheral edge of the circular portion 11 of the frame 10 coincide with each other. An ear pad 40 having a diameter substantially the same as the diameter of the baffle 20 is fixed to the outer edge portion 21 of the baffle 20.

  As described above, when the frame 10 is fixed to the band member 2, the side pressure generated by the spring property of the band member 2 and the rigidity of the frame 10 is evenly distributed to the entire periphery of the user's auricle via the ear pad 40. Join. In this case, the direction of the lateral pressure applied through the ear pad 40 is the right direction on the paper surface of FIG.

  Note that the shape of the circular portion 11 of the frame 10 is preferably elliptical. In accordance with this, it is desirable that the outer shape of the ear pad 40 is also elliptical. If the ear pad 40 is oval, the ear pad 40 comes into contact with the periphery of the auricle so as to cover the periphery of the auricle, and the lateral pressure is applied more evenly. As a result, a comfortable wearing feeling can be given.

  When the ear pad 40 is elliptical, for example, if the headphone 100 is a neck-mounted type, the long diameters of the ear pad 40 and the frame 10 intersect with the longitudinal direction of the band member 2. In other words, the major axis of the frame 10 is a direction along the longitudinal direction of the user's ear when worn.

  As shown in FIG. 3, the inclined portion 22 of the baffle 20 is inclined with respect to the circular partial plane of the circular portion 11 of the frame 10. In FIG. 3, the band fixing portion 12 protrudes from the vicinity of the location where the baffle 20 and the ear pad 40 are farthest apart. For example, if the headphones 100 are a neck-mounted type, the protruding direction of the band fixing portion 12 is the user's occipital side.

  FIG. 4 is a diagram illustrating an example of a usage state of the headphones 100. As shown in FIG. 4, the headphones 100 are, for example, a neck type (backband type). When the headphone 100 of the neck type is worn on the user's head, the band member 2 is wound around the back of the neck so that it is applied to the user's neck and lateral pressure is applied to the headphone unit 1 at the auricular position. It is done.

  Since the driver unit 30 is fixed along the inclined portion 22, the diaphragm is inclined with respect to the surface where the ear pad 40 faces the peripheral portion of the user's auricle. When the user wears the headphones 100, the space between the left and right headphone units 1 is widened. Then, in FIG. 3, the headphone unit 1 rotates and moves to the left side of the page with the top of the band member 2 as a fulcrum, so that the diaphragm of the driver unit 30 faces the user's ear canal. As described above, the driver unit 30 is inclined in advance with respect to the tangent of the joint portion between the band member 2 and the headphone unit 1 in consideration of the positional relationship between the diaphragm and the user's ear when worn.

  The headphone 100 described above can be comfortably worn by the user even when worn for a long time, and can be configured with a small number of components.

  In addition, since the lateral pressure is uniformly applied to the entire ear pad 40, the user is less likely to feel tired even if the headphones 100 are worn for a long time.

  In addition, the headphones 100 can be reduced in weight by reducing the size of the frame 10 to the minimum size around the pinna. As a result, even if the lateral pressure applied by the band member 2 is weak, the headphone unit 1 is held at a predetermined position without being displaced.

  Further, the headphone 100 can complete the structure for holding the entire headphone unit 1 with only the frame 10 close to the user's ear. As a result, the headphone unit 1 can be made thin, and the headphone 100 as a whole has a good appearance when worn.

  Furthermore, the headphone 100 is advantageous in terms of manufacturing cost because the number of parts can be greatly reduced as compared with the conventional one.

  Moreover, the headphones according to the present invention are not limited to the neck type, and can be applied to a type in which the band member 2 straddles the upper part of the user's head.
