Description

  The present invention relates to an ear-mounted headphone provided with an ear hanger hung on an auricle.

There is known an ear-mounted headphone equipped with an ear-hanging hanger to be hung on an auricle, and an example is described in Patent Document 1.
The earphone is configured so that when the ear hanger is hung on the auricle, the main body abuts on the auricle so as to cover the external auditory canal, and the wearing posture is stabilized.

JP 2003-333678 A

The ear-mounted headphones are used not only for music appreciation but also for many purposes because the mounting posture on the pinna E is relatively stable. For example, for business wireless communication.
In commercial wireless communication applications, it is used by connecting to a transceiver such as a transceiver. The wearing time of the earphones in this application is generally much longer than that for music appreciation and is generally worn continuously.

By the way, the auricle E has a tragus E8 and an antitragus E9 as projecting portions projecting outward on the head side of the exit edge and the lower side of the exit edge in the external auditory canal E7 (see FIG. 8).
The tragus E8 and the antitragus E9 are so-called waist protruding portions that are harder than the earlobe E2 or the like of the pinna E.
When the surface of the headphone that contacts the auricle E is a flat surface as described in Patent Document 1, regardless of the presence or absence of the ear pad, or the dome shape protruding toward the auricle E side, the auricle E In the mounted state, the headphone main body may come into contact with the protruding portions (the tragus E8 and the tragus E9), and the protruding portion may be pushed in.
If the headphones have been worn for a long time, the protruding portion will continue to be pushed during that time, so that discomfort may occur and a good wearing feeling may not be maintained, and an improvement has been desired.

  Therefore, the problem to be solved by the present invention is to provide an earphone that can maintain a good wearing feeling even when worn for a long time.

In order to solve the above problems, the present invention has the following configuration.
A main body portion having a speaker unit (SP) and a grille portion (1a1) in which the speaker unit (SP) is accommodated and a sound emitting hole (1a2) for emitting sound from the speaker unit (SP) to the outside is formed (1), an ear hooking part (3) connected to one peripheral edge of the main body part (1), and on the outer side in the extending direction with respect to the grill part (1a1), more sound is emitted than the grill part (1a1). Ear pad (1a4) protruding in the direction,
With
By hanging the ear hook (3) on the auricle (E), a part of the outer surface of the ear pad (1a4) can be used with the grill (1a1) as the auricle (E) side. Abutting the inner side of the ear ring (E4)
An ear-mounted headphone (51) characterized in that the tragus (E8) of the auricle (E) is configured to be in a wearing state at a position corresponding to the grill portion (1a1).

  According to the present invention, there is an effect that a good wearing feeling is maintained even when worn for a long time.

The earphones according to the embodiment of the present invention will be described with reference to FIGS. 1 to 14 by preferred examples and modifications.
In the following description, the up / down, front / back, left / right directions are defined in the directions of the arrows in each figure. This direction is not related to the direction in the posture in use, and is defined for convenience in order to facilitate understanding.

(Example)
An embodiment of the earphone is a headphone 51. First, the configuration will be described with reference to FIGS. 1 is a perspective view of the headphone 51, FIG. 2 is a front view, FIG. 3 is a rear view, FIG. 4 is a right side view, and FIG. 5 is a partial cross-sectional view corresponding to FIG. FIG. 6 is a schematic top view for explaining when the left ear is used and when the right ear is used.

The headphones 51 include a speaker unit SP having a diaphragm SPa, a flat bowl-shaped front housing 1a in which the speaker unit SP is fixed on the inner surface side, a flat bowl-shaped rear housing 1b that covers the rear side of the front housing 1a, One end side is connected to a terminal portion SPb provided on the rear surface of the speaker unit SP, and the other end side is pulled out from a cord hole 1c provided in a peripheral portion on the lower side of the rear housing 1b, and a cord hole 1c. A bushing 2 inserted so as to cover the cord C, a columnar connecting portion 1d which is provided on one upper peripheral edge of the front housing 1a and protrudes upward, and an ear hooking portion 3 connected to the connecting portion 1d ( And an ear hanger 3).
The cord C is formed by tying a knotting ball Ca for preventing the removal.

The front housing 1a and the rear housing 1b are integrated by bonding or welding to form the main body 1.
The speaker unit SP is housed inside the main body 1 in such a posture that the diaphragm SPa is on the front housing 1a side.
In this example, the main body 1 is formed in a substantially circular shape in rear view. The shape of the rear view is not limited to a perfect circle, and may be an ellipse, an ellipse, a triangle, a rectangle, or the like. Since this rear view shape can be visually recognized as the appearance of a product, it is generally determined with priority on design while considering the function.
The front housing 1a and the rear housing 1b are made of resin. An example of the material is ABS (acrylonitrile butadiene styrene).

The ear hanger 3 is formed in an arc shape that substantially conforms to the root shape between the head of the pinna E (see FIGS. 7 and 8). The angle range formed in an arc shape is preferably a range of 180 ° or more from the upper end portion where the ear hanger 3 is connected to the main body portion 1 to at least the lower end portion of the main body portion 1.
If it is formed in the range of 180 ° or more, it is preferable because the pinching of the pinna E by the ear hanger 3 becomes more reliable and the wearing posture is more stable.
In the headphone 51, as is clear from FIG. 3 and the like, the arc range is formed at about 230 ° which is 180 ° or more.

  The ear-hanging hanger 3 has a basic range in which a core material made of POM (polyacetal) is covered with TPE (thermoplastic elastomer) in a range of approximately 100 ° on the connecting portion 1d side when the axis CL1 of the speaker unit SP is the center. The remaining tip side is a tip portion 3b formed of only TPE.

Since there is a core material made of POM that is higher in rigidity than TPE, the root portion 3a is deformed while generating a certain amount of elastic repulsion. In the sensory expression, the so-called waist is deformed.
By this elastic repulsion force, the main body 1 can be attached to the auricle E with an appropriate urging force.
The tip 3b is more flexible than the root 3a and easily deforms.
Thereby, the mounting | wearing to the pinna E of the headphone 51 performed while deform | transforming the ear hanger 3 becomes smoother. Further, when the ear hanger 3 is rotated when the ear to be attached is changed to the other ear (this rotation will be described later), it is easy to get over the interfering bushing 2.

  The headphone 51 may be attachable to both the left and right ears. The headphone 51 shown in FIGS. 1 to 4 is an example that can be worn on both the left and right ears. For this purpose, the ear hanger 3 is formed in a two-dimensional arc shape without bending in the thickness direction.

Corresponding to the central portion of the diaphragm SPa projecting forward, the portion facing the diaphragm SPa of the front housing 1a is also a dome-shaped grill portion 1a1 projecting forward.
A plurality of sound emission holes 1a2 for emitting sound from the diaphragm SPa to the outside are formed in the grill portion 1a1.
The area | region in which the some sound emission hole 1a2 in the grill part 1a1 was formed is called the sound emission part 1a3.

In the front housing 1a, an ear pad portion 1a4 that protrudes in the front direction, which is the sound emitting direction, is formed with respect to the grill portion 1a1 at a portion on the outer side in the extending direction of the grill portion 1a1.
If the protruding height from the boundary position of the ear pad portion 1a4 with the grill portion 1a1 as the root is the protruding height Ht (see FIG. 5), the protruding height Ht of the ear pad portion 1a4 is constant, for example. (See FIG. 12).
Further, as shown in FIGS. 1 and 5, the ear pad 1a4 is formed to extend in the circumferential direction, and the protrusion height Ht1 at the predetermined position P1 in the circumferential direction of the ear pad 1a4 is the highest. In addition, the protrusion height Ht may be inclined so that the protrusion height Ht decreases as the distance from the predetermined position P1 increases.

In the headphone 51, for example, the inclination angle is substantially constant.
That is, the tip edge line of the ear pad 1a4 is included in the virtual plane SF1. The virtual plane SF1 is, for example, a plane that is oblique to the axis CL1 of the speaker unit SP.
In FIG. 4 and the like, the edge ridge line of the ear pad 1a4 is described in a curved shape that is slightly convex forward. However, from the viewpoint of the function and the obtained effect, it is substantially the same as that having a constant inclination angle. You can see.

In the headphone 51, the predetermined position P <b> 1 is an upper end in the peripheral portion of the main body 1. Therefore, the virtual plane SF1 is a surface extending in the direction orthogonal to the paper surface of FIG.
More specifically, in FIG. 5, when the virtual plane SF2 including the rotation axis CL2 and orthogonal to the paper surface is defined, the angle (subordinate angle) of the virtual plane SF1 with respect to the virtual plane SF2 is inclined by the angle θa.
The inclination direction of the angle θa is a direction in which the ear pad 1a4 is separated from the head HD as it goes from the upper side to the lower side when the headphones 51 are worn.
The angle θa is not limited. For example, it is 8 to 10 °.

  As described above, in the headphones 51, the predetermined position P1 coincides with the position where the connecting portion 1d is provided. This match does not need to match exactly, but should just match.

The lead-out direction of the cord C of the headphone 51 is set downward.
Specifically, it is pulled out in the direction opposite to the upward direction, which is the protruding direction of the connecting portion 1d. This is because the headphones 51 can be worn on both the left and right ears.
When the headphones for exclusive use of the left and right ears are used, the direction in which the cord C is pulled out is not limited.
However, it is more preferable that the cord C is pulled out to the lower side of the auricle E in the worn state because the routing becomes natural.

  In order to make the headphone 51 attachable to both the left and right ears, the ear hanger 3 is formed in a two-dimensional arc shape without bending in the thickness direction as described above. It rotates in 1d. Specifically, as shown in FIGS. 6 (a) and 6 (b) which are top views, the ear hanger 3 is at least 180 ° around the rotation axis CL2 that is the axis thereof at the connecting portion 1d. It is connected so as to rotate.

The turning direction of the ear hanger 3 at the connecting portion 1d is not limited, and may be either the clockwise direction (arrow DR2) or the counterclockwise direction (arrow DR3) in FIG.
FIG. 6A shows a left-ear rotation position that allows left ear mounting, and FIG. 6B shows a right-turn position that enables right ear mounting.
In the rotation between the left rotation position and the right rotation position, the bushing 2 exists on the rotation path of the tip 3b of the ear hanger 3. That is, the bushing 2 interferes with the rotation of the ear hanger 3.
On the other hand, the ear-hanging hanger 3 has the tip portion 3b formed extremely flexibly, so that it can easily get over the bushing 2 by being deformed.
When the headphone 51 can be attached to both the left and right ears, if the rotation axis CL2 is set so as to intersect the axis CL1 of the speaker unit SP, the positions of the speaker unit SP are equivalent to the left ear and the right ear. It will be good.

  Next, a state in which the headphones 51 are attached to the auricle E will be described with reference to FIGS. In the following description, a case where the ear hanger 3 is attached to the left ear will be described. When worn on the right ear, it is just the opposite, and the rest is the same.

FIG. 7 is a perspective view showing a state in which the headphones 51 are attached to the left pinna E. FIG. 8 shows the pinna E in a state where the headphones 51 are not worn as compared to FIG.
In the wearing state shown in FIG. 7, the ear hanger 3 is housed in a valley between the ear ring E <b> 1 and the head HD in the pinna E and is hung along the base outside the pinna E.
Here, the ear hanger 3 has an arc-shaped range of about 230 ° as described above, so the vicinity of the tip of the tip 3b reaches between the earlobe E2 and the head HD.

The pinna E rises and protrudes so as to move away from the head HD toward the back of the head. Accordingly, the ear hanger 3 hung on the pinna E is three-dimensionally deformed in the thickness direction (see the arrow DR1 in FIG. 4) with respect to the main body 1.
Therefore, an elastic repulsive force is generated in the ear hanger 3 so as to restore the deformation, and the main body 1 is held by the elastic repulsive force so that the ear ring E1 is sandwiched between the ear hanger 3 and the ear hanger 3. It is energized to the E side. This urging force also contributes to stable wearing of the headphones 51 to the pinna E.

  In the mounted state, the connecting portion 1d is located in the vicinity of the face side end portion of the ear ring leg E3. The cord C is drawn downward along the earlobe E2. Therefore, the headphone 51 is in a posture in which the headphone 51 is tilted so that the upper side of the rotation axis CL2 approaches the face side in the wearing state.

  The main body 1 is in a mounted state so that the upper side is generally contained in the concha boat E5 and the concha cavity E6, which are concave portions on the face side of the antiauricle E4, that is, a part of the outer surface of the ear pad 1a4. In contact with the inner side of the ear ring E4, the ear canal E7 projecting in the direction away from the head HD on the face side of the ear canal E7, and the direction away from the head HD on the lower side of the ear canal E7 The outer shape and dimensions are set so as to cover the protruding anti-tragus E9.

FIG. 9 is a view taken along arrow Y1 in FIG. 7 and is a diagram schematically showing the range of the auricle E covered by the main body 1. The pinna E in FIG. 9 is described in a size that is considered to be the most common standard for designing the headphones 51.
A solid line in the main body portion 1 corresponds to an outline line, and a line LN1 indicated by an alternate long and short dash line indicates a line where the ear pad portion 1a4 connects to the root grill portion 1a1. That is, the range surrounded by the line LN1 corresponds to the range corresponding to the grill portion 1a1.

As shown in FIG. 9, with the headphones 51 attached, the tragus E8 is located within a range corresponding to the grill 1a1 surrounded by the ear pads 1a4.
In the mounted state, the grille 1a1 is in a recessed position away from the head HD relative to the ear pad 1a4.
Therefore, the tragus E8 is in a state where it does not come into contact with the grill portion 1a1, or a state where it comes into contact with a smaller amount of deformation than in the prior art.

  The relationship between the height positions of the tragus E8 and the grill portion 1a1 is shown in FIG. FIG. 10 is a schematic cross-sectional view at the position S1-S1 in FIG.

As shown in FIG. 10, the grill portion 1a1 is formed to be recessed with respect to the tip portion of the ear pad portion 1a4 so as to be separated from the head HD, and in the mounted state, the tragus E8 enters the recess. Yes.
Thereby, the headphone 51 is an example of a contact surface position of the conventional headphone without the ear pad 1a4 and the grille 1a1 projecting in a dome shape on the flat surface or the auricle E side (the case of the flat surface is illustrated as a line LN2. ), The deformation of the tragus E8, which is the protruding portion, does not occur, or even if it occurs, a slight deformation is sufficient.

As described above, in the headphone 51, the main body 1 has the ear pad 1a4 protruding in the sound emission direction from the grill 1a1 on the outer side in the radial direction than the grill 1a1 having the sound emission 1a3. Is formed.
Further, the main body 1 is in a position corresponding to the grille portion 1a1 in which the tragus E8, which is a protruding portion, is recessed in a direction away from the head HD with respect to the ear pad 1a4 when the headphones 51 are attached. Is formed.
Thereby, even if the headphones 51 are used for a long time, discomfort does not easily occur and a good wearing feeling is maintained.

  The larger (higher) the protruding height Ht of the ear pad 1a4 is, the lower the possibility that the tragus E8 will come into contact with the grill 1a1 and the amount of deformation will be reduced even if it comes into contact.

  By the way, the size of the pinna E varies among individuals. In particular, when the headphones 51 are attached to the auricle E, the difference in the portion of the auricle E corresponding to the lower end of the ear pad 1a4 is relatively large.

In the headphone 51, as shown in FIG. 9, in the auricle E having a reference size, the lower end portion of the main body 1 is made to correspond to the position of the tragus E9. This is because the rear view of the main body 1 is generally circular from the viewpoint of design, and the upper side of the main body 1 is divided into the concha boat E5 and the concha cavity E6, which are the concave portions on the face side of the antiauricle E4. It depends on the fact that it is generally fit.
Since the anti-auricle E9 is a protruding part, there is a possibility that a large difference in wearing feeling may occur due to the difference in the size of the pinna E. The difference in wearing feeling due to this difference is reduced, and as good as possible without individual differences It is desired that a comfortable wearing feeling is obtained.

Therefore, the ear pad 1a of the headphone 51 is formed in an arc shape that substantially surrounds the entire circumference of the grill portion 1a1, or an annular shape that completely surrounds the entire periphery, and a protrusion height Ht with respect to the grill portion 1a1 is provided. It is good to form so that it may become the maximum in the circumferential direction position and it may become so low that it leaves | separates from the connection part 1d.
Thereby, the difference in the wearing feeling due to the difference in the size of the pinna E can be satisfactorily reduced. This will be described with reference to FIG.

11A to 11C are schematic cross-sectional views at the position S2-S2 in FIG. 9 in a wearing state in which the headphones 51 are worn on the auricle E. FIG.
11A is a wearing state of the auricle E having a design standard size, FIG. 11B is a wearing state of the auricle Ea smaller than the auricle E, and FIG. 11C is an auricle. The wearing state in the pinna Eb larger than E is shown.

In general, in the earphone, the posture in the mounted state is generally determined by the shape of the ear hanger 3 and the shape of the main body 1 in the vicinity of the connecting portion 1d to which the ear hanger 3 is connected. The same applies to the headphones 51.
Therefore, in FIGS. 11A to 11C, for the sake of easy understanding, description will be made assuming that the position and orientation of each virtual plane SF2 are the same.

11A to 11C, a position where the upper end of the tip ridge line of the ear pad 1a4 contacts the auricle E is defined as a position P2, and a virtual plane SF2A passing through the position P2 is set parallel to the virtual plane SF2. .
At this time, since the virtual plane SF1 including the tip edge line of the ear pad portion 1a4 is inclined by the angle θa with respect to the virtual plane SF2, the position P3 of the lower end of the ear pad portion 1a4 is behind the virtual plane SF2A. It is in.

For example, in the case of the auricle E having the reference size shown in FIG. 11A, the position P3 is located at a lower part of the anti-tragus E9, and a slight gap is generated without contact. ing.
That is, even if the headphones 51 are worn for a long time, the lower side of the main body 1 does not come into contact with the tragus E9, which is a protruding portion, and does not bias it.
Therefore, a good wearing feeling is maintained even if the headphones 51 are worn for a long time.

In the case of the small auricle Ea shown in FIG. 11 (b), the position P3 is located at the part of the earlobe E2 below the antitragus E9, and the ear pad 1a4 is in contact with the earlobe E2.
Here, since the earlobe E2 is an extremely soft and easily deformed part, even when the headphones 51 are worn for a long time, discomfort does not easily occur and a relatively good wearing is maintained.

In the case of the large auricle Eb shown in FIG. 11C, the position P3 is at a position corresponding to the concha cavity E6. Since the concha cavity E6 is a recessed portion, the lower portion of the main body 1 that is inclined away from the pinna E with an angle θa does not contact the pinna E.
Thereby, even if the headphones 51 are worn for a long time, the lower side of the main body 1 does not come into contact with the protruding portion and does not bias it.
Therefore, a good wearing feeling is maintained even when worn for a long time.

  As described above, the headphone 51 is formed in an arc shape that surrounds the grill portion 1a1 substantially around the entire circumference, or in an annular shape that completely surrounds the entire circumference. Even if it is worn for a long time regardless of the size of the pinna E, it is maximized at the position and formed so as to become smaller as it goes away from the connecting portion 1d in the extending direction of the ear pad portion 1a. A comfortable wearing feeling is maintained.

Further, when the headphone 51 is attached to the pinna E, the ear hanger 3 is bent in the direction of the arrow DR1 in FIG. 4 while the ear hanger 3 is bent between the ear hanger 3 and the position P3 which is the lower end position of the ear pad 1a4. Insert the ear ring E1 from above.
Here, when the protruding height Ht of the ear pad 1a4 is formed so as to become lower from the connecting part 1d along the extending direction of the ear pad 1a, the ear hanger 3 is not bent. However, since a certain amount of gap is generated between the lower end portion of the ear pad 1a4 and the ear hanger 3, it is easy to insert the ear ring E1. Further, the amount of deformation of the ear hanger 3 when inserted is small. That is, it becomes easier to attach the headphones 51 to the pinna E.

Further, as shown in FIG. 4, the headphone 51 has a ridge line on the front side of the connecting portion 1d substantially parallel to the virtual plane SF2 in the area AR1.
The lower end of the area AR1 is a position P2 corresponding to the upper end of the ear pad 1a4, and the upper end is a position P4 of the upper end of the connecting portion 1d.
Since the area AR1 extending in the up and down direction comes into contact with the head HD in the mounted state, the headphone 51 is less likely to rotate (arrow DR4) about the position P2 of the main body 1. , The mounting posture is more stable.

The headphone 51 has an ear pad 1a4 projecting in the sound emission direction from the grill 1a1 on the outer side in the radial direction than the grill 1a1. When the grill portion 1a1 has a dome shape, the most projecting portion in the direction of the axis CL1 does not exceed the virtual plane SF1.
As a result, even if the headphone 51 dropped on the floor or the like is accidentally stepped on with a shoe from above, the ear pad 1a4 hits the floor or the shoe sole instead of the grill 1a1. That is, an excessive force is not applied to the grill portion 1a1, which has a lower strength than the non-piercing case due to the plurality of sound emitting holes 1a2, and the ear pad portion having a relatively high strength. The force is received at 1a4.
As a result, the headphones 51 are less likely to damage the grill portion 1a1.

  The embodiment of the present invention is not limited to the above-described configuration, and may be modified as shown below without departing from the gist of the present invention.

In the embodiment, the example in which the ear pad 1a4 is formed integrally with the front housing 1a has been described. However, the headphone 51A in which the ear pad 1a4 and the part other than the ear pad 1a4 of the main body 1 are separated. It may be.
As shown in FIG. 13, the headphone 51 </ b> A includes a main body 1 </ b> A having a shape excluding a portion corresponding to the ear pad 1 a <b> 4 and an ear pad 1 a <b> 4 </ b> A having a shape corresponding to the ear pad 1 a <b> 4. , Are combined. A well-known method such as adhesion, welding, and fitting can be applied to the structure of this combination.
In the ear pad 1a4A, an escape portion N is formed so that the connecting portion 1d does not interfere.
In FIG. 13, as the ear pad 1a4A, the ear pad 1a4A1 formed so that the protruding height Ht is substantially constant in the circumferential direction, and the ear whose protruding height Ht decreases as the distance from the connecting part 1d side increases. The pad 1a4A2 is illustrated.

The ear pad 1a4A may be formed of a resin material such as ABS or elastomer, similarly to the headphone 51A. Moreover, you may form with rubber materials, such as silicone rubber.
The ear pad 1a4A may be detachable from the main body 1A.
When making it detachable, it may be formed of a foam material such as urethane foam and function as an ear pad.
In commercial wireless communication applications, waterproof performance or drip-proof performance that is expected to be used during rainfall is required, and therefore it is necessary to select materials with sufficient consideration for these performances. In this respect, as described in the embodiment, the ear pad 1a4 is preferably formed integrally with the front housing 1a made of resin.

In FIG. 14A, the ear pad portion 1a4 is not limited to an arc shape that surrounds the grill portion 1a1 almost entirely, or an annular shape that completely surrounds the entire periphery.
As an arc shape, a partially formed arc shape as shown in FIG.
Moreover, as shown in FIG. 14B, a plurality of columnar ear pads 1e spaced apart in the circumferential direction may be used.
When the headphone 51 can be worn on both the left and right ears, the peripheral shape of the main body 1 in the rear view is preferably symmetrical with respect to the rotation axis CL2. Thereby, the feeling of wearing in the right ear and the left ear becomes equivalent.

  The above-described embodiments and modifications can be freely combined with each other as much as possible.
