Description

  The present technology relates to a headphone storage device that stores headphones.

  Headphones are widely used to listen to sound reproduced by a portable music player or the like. Since the portable music player can be taken out outdoors, the headphones are often taken out outdoors. In such a case, a carrying case that makes it easy to carry the headphones by storing the headphones is often used.

  The carrying case for headphones is required to store the headphones as compactly as possible so as not to get in the way when carrying. Therefore, in the headphone carrying case, the contact surfaces of the pair of ear pads that face the user's temporal region of the pair of ear pads constituting the headphones are not opposed to each other, but the contact surfaces of the pair of ear pads face the same direction. It is normal to store headphones (no prior art document). In this state, the contact surface of the ear pad is in contact with the inner surface of the carrying case.

  However, when the headphones are housed in this manner, the opening formed on the contact surface of the earpad is blocked by the inner surface of the carrying case. Then, when the ear pad is pressed by a force from the outside of the carrying case, the air in the ear pad is not discharged from the opening, and the air compresses the driver unit, the circuit, etc. of the headphones. As a result, the headphones may break down.

  Accordingly, an object of the present technology is to provide a headphone storage device in which a headphone does not break down even if a force is applied to the earphone of the stored headphone.

  In order to solve the above-described problem, the present technology provides a case main body that houses headphones therein, and a surface of the case main body that faces the contact surface of the ear pad that constitutes the headphones. It is a headphone storage apparatus which consists of a plate-shaped object in which is formed.

  According to the present technology, it is possible to prevent the stored headphones from being damaged by an external force.

<1. Embodiment>
[1-1. Configuration of headphones]
FIG. 1 is a diagram showing an external configuration of the headphones 1. The headband 2 is formed in a curved shape along the user's head, and supports the headphone 1 as a whole by contacting the user's head when the headphone is worn. The headband 2 is made of a synthetic resin such as plastic, metal, or the like, and has flexibility by having predetermined rigidity and elasticity. Thereby, at the time of wearing, the housing 5 and the ear pad 8 can be pressed toward the user's temporal region to maintain the wearing state of the headphones 1.

  For example, the entire headband 2 is covered with a sponge as a cushioning material, and the sponge is further covered with synthetic leather. In addition, instead of covering the entire headband with a cushioning material, rubber, sponge, or the like may be provided as a cushioning material on a portion of the inner surface of the headband 2 that comes into contact with the user's head. Thereby, the discomfort by a hard headband contacting a user's head can be reduced. Further, a hinge may be provided at the approximate center of the headband 2 so that it can be folded when being carried.

  The slider 3 is provided at both ends of the headband 2. The slider 3 is provided with a hanger 4. The slider 3 is configured to be slidable inside the headband 2. By sliding the slider 3, the hanger 4 can be moved downward or upward with respect to the headband 2. When the headphones 1 are worn, the housing 5 and the ear pad 8 are adjusted to a position facing the user's ear by adjusting the degree of expansion / contraction of the slider 3 according to the size of the user's head and the distance between the ear and the top of the head. I can do things. Thereby, the user can obtain a feeling of wearing according to his / her physical characteristics and preferences. On the other hand, when the headphones 1 are not used, the storage space can be saved by making the slider 3 contracted.

  The hanger 4 is provided at the tip of the slider 3, and each supports the housing 5 in a freely rotatable manner. In the present embodiment, the hanger 4 includes a slider connection portion 4A, an intermediate portion 4B, a housing support portion 4C, and a hinge portion 4D. The slider connection portion 4A is a portion connected to the slider 3 described above. The intermediate portion 4B is interposed between the slider connection portion 4A and the housing support portion 4C. The slider connecting portion 4A and the intermediate portion 4B are connected via a hinge 4D. Thus, the headphone 1 can be bent in the α direction with the hinge portion 4D as a fulcrum.

  The housing support portion 4C supports the housing 5 in a rotatable manner. The housing support portion 4C has a bifurcated shape, and supports the housing 5 in a rotatable manner by being pivotally supported by support pins (not shown) that protrude inward from a pair of tips. Thereby, when the headphones 1 are worn, the orientation of the housing 5 changes in accordance with the shape around the user's ear, so the housing 5 can be made to face the ear in a state suitable for the shape of the user's temporal region. it can.

  Furthermore, the housing support portion 4C is configured to be rotatable in the β direction by being connected to the intermediate portion 4B via a rotation shaft (not shown).

  The housing 5 functions as a housing portion that houses a sound processing circuit, a noise canceling processing circuit, a driver unit (none of which are shown), and the like. The housing 5 is formed using, for example, a synthetic resin such as plastic. For example, the audio processing circuit performs predetermined audio signal processing such as signal amplification processing and equalizing processing on an audio signal for driving a speaker. The speaker is sound output means for outputting a sound signal processed by the sound processing circuit as sound.

  As shown in FIG. 1B, a microphone 6 for collecting external sound as noise is provided on the side surface of the housing 5. For example, in the noise canceling processing circuit, a reverse phase sound is generated by inverting the phase of the sound collected by the microphone 6, and noise canceling is performed by using it. The housing 5 is provided with a switch 7 for switching on / off of the noise canceling function.

  The ear pad 8 is configured to have high airtightness and flexibility by using a flexible material such as urethane and a synthetic leather covering the outer periphery thereof. The ear pad 8 is provided on the surface of the housing 5 that faces the user's temporal region.

  The ear pad 8 functions as a buffer member between the housing 5 and the user's temporal region by being interposed between the housing 5 and the user's temporal region. That is, the earpad 8 prevents the housing 5 formed of a hard material that is difficult to deform when the headphones 1 are worn from coming into direct contact with the user's temporal region and causing discomfort or pain to the user.

  Since the ear pad 8 has high airtightness, it also plays a role of improving sound quality such as improvement of reproducibility of a low sound range. Also, it plays a role of preventing sound output from the speaker from leaking outside. Further, the ear pad 8 also serves to make it easier to listen to the sound from the speaker by blocking external noise.

  As shown in FIG. 1C, the ear pad 8 is configured in a cylindrical shape having an opening 8 </ b> A formed substantially at the center of the surface on the side in contact with the user's temporal region. Sound from the driver unit is output to the outside through the opening 8A. When the ear pad 8 is pressed from the outside, the air in the ear pad 8 is discharged to the outside from the opening 8A.

  If the ear pad 8 is pressed from the outside when the opening 8A is closed and the opening 8A is closed, air is not discharged from the opening 8A to the outside, but is compressed in the ear pad 8 and the driver unit. It will put a load on. This may cause a failure of the driver unit or the like.

  A net 9 is provided so as to cover the opening 8A of the earpad 8. The net 9 is for preventing dust from entering the driver unit, the audio processing circuit, and the like housed in the housing 5. Since the net 9 is configured in a mesh shape, the presence of the net 9 does not hinder the discharge of air from the opening 8A.

  As shown in FIG. 1B, a female plug 10 for connecting a cord is provided in one of the pair of housings 5, 5. The female plug 10 is electrically connected to the sound processing circuit inside the housing 5.

  The cord 11 has a left channel lead L, a right channel lead R, a ground wire G, and the like inserted therein, and transmits a sound signal to the headphones 1. A male plug 11 </ b> A is provided at one end of the cord 11, and the cord 11 is connected to the housing 5 by inserting the male plug 11 </ b> A into the female plug 10 of the housing 5. Thus, the cord 11 is configured to be detachable from the housing 5. By configuring the cord 11 to be detachable, the cord 11 can be detached from the headphone 1 when the headphone 1 is folded and stored.

  A plug (not shown) is provided at the other end of the cord 11. By connecting the plug to an audio playback device (not shown) such as an MP3 player, the headphones 1 are connected to the audio playback device.

In order to drive the speaker in the other housing 5 to which the cord 11 is not connected, a connecting cord is provided between the housing 5 to which the cord 11 is connected and the other housing 5 to which the cord 11 is not connected. (Not shown) is provided. The connection cord is connected to the cord 11 or the audio processing circuit in the housing 5 to which the cord 11 is connected, and is inserted into the hanger 4, the slider 3, and the headband 2 to the audio processing circuit in the other housing 5. Connected. With this connection cord, an audio signal is transmitted to the audio processing circuit in the other housing 5 to which the cord 11 is not connected. However, two cords may be connected to the left and right housings 5 so as to supply audio signals to the audio processing circuits in both the left and right housings 5, respectively.

  FIG. 2A is a plan view showing a state in which the headphones 1 are folded. As described above, the hanger 4 is configured to be bendable in the α direction with the hinge 4D as a fulcrum. Further, the housing support portion 4C of the hanger 4 is configured to be rotatable in the β direction. Therefore, as shown in FIG. 2A, the pair of ear pads 8 and 8 can face each other in the same direction, not facing each other. In this way, the earphone 8 can be directed in the same direction, so that the headphones 1 can be made thin. As a result, the headphones 1 can be stored in the carrying case 100 in a more compact manner. Headphone 1 in the present embodiment is housed in carrying case 100 in a folded state as shown in FIG. 2B. The configuration of the carrying case 100 will be described later.

[1-2. Configuration of Headphone Storage Device]
Next, the configuration of the carrying case 100 as a headphone storage device that stores the headphones described above will be described. FIG. 3 is a perspective view showing an external configuration of the carrying case 100. 3A shows the closed state of the carrying case 100, and FIG. 3B shows the opened state of the carrying case 100. FIG.

  The carrying case 100 includes a case main body 200, a plate-like body 300 as a core material provided in the case main body 200, and a cover portion 400 that covers the plate-like body 300.

  The case main body 200 includes a storage unit 210 that stores headphones, and a lid unit 220 that opens and closes the storage unit 210. The storage unit 210 and the lid unit 220 are configured by covering the outer surface of a member having a certain degree of hardness, such as cardboard or plastic, with synthetic leather or the like, and further covering the inner surface with a cloth or the like.

  The storage unit 210 is configured to open upward from a flat bottom surface part 211 and a side surface part 212 formed in a curved surface shape. The side surface portion 212 is formed in a curved surface so that the headband 2 of the headphone 1 extends along the side surface portion 212. Thereby, the headphones 1 can be stored compactly. Moreover, the side part 212 is formed so that it may open | release in one direction, as shown to FIG. 3B.

  The lid part 220 is for opening and closing the storage part 210 that is open upward. The lid part 220 is coupled to the bottom part 211 of the storage part 210 by sewing, for example. The lid part 220 is bent at the joint with the bottom part 211 so as to cover the opening part of the storage part 210 and close the storage part 210. For example, the lid 220 may be maintained in a closed state with a fastener, a nylon adhesive tape, a button, or the like. In addition, the lid part 220 and the storage part 210 may not be configured as separate members but may be configured integrally with one member.

  A bag portion 221 is provided on the inner surface of the lid portion 220 by, for example, sewing a cloth. The bag portion 221 can store, for example, the cord 11 removed from the headphones, a battery, and the like. In addition, by providing an elastic body such as rubber at the edge of the lid portion 220, the bag portion 221 is naturally closed by the elastic force, and the cords stored in the lid portion 220 are prevented from being accidentally dropped. can do.

  FIG. 4 is a perspective view showing a state in which the carrying case 100 is disassembled. On the bottom surface portion 211 of the case body 200 constituting the carrying case 100, a plate-like body 300 as a core material is provided. Further, a cover part 400 is provided on the plate-like body 300. That is, the bottom side of the carrying case 100 has a three-layer laminated structure. The bottom surface portion 211, the plate-like body 300, and the cover portion 400 are fixed with, for example, an adhesive.

  The plate-like body 300 is configured using a member having a certain degree of hardness, such as cardboard or plastic, and is formed in a flat plate shape. The plate-like body 300 is provided to maintain the shape of the carrying case 100.

  A pair of grooves 310 and 310 are formed in the plate-like body 300. The groove 310 corresponds to an air flow portion in the claims. The function of the groove 310 as an air flow portion will be described later. Furthermore, an air discharge part 320 is formed in the plate-like body 300 so as to be connected to the pair of grooves 310, 310. The air discharge part 320 is formed so as to cut out a part of the plate-like body 300. As will be described in detail later, the air discharge section 320 functions as an air vent for the air that has passed through the groove 310 to escape to the outside.

  The cover part 400 is comprised with the material which has air permeability, such as cloth. A partition portion 410 is provided on the upper surface of the cover portion 400 so as to stand upward. The partition portion 410 is for preventing the housings 5 from coming into contact with each other and being damaged by being interposed between the pair of housings 5 when the headphones are housed in the housing portion 210.

[1-3. Effects of the headphone storage device]
FIG. 5 is a diagram illustrating a state where the headphones 1 are stored in the carrying case 100. For convenience of explanation, the cover 400 is omitted, the headphones 1 are indicated by broken lines, and the plate-like body 300 is indicated by thick lines.

  As shown in FIG. 5, the pair of grooves 310, 310 are respectively formed at positions corresponding to the openings 8 </ b> A, 8 </ b> A formed in the approximate center of the pair of ear pads 8, 8. Further, the air discharge unit 320 is formed at a position where the ear pads 8 and 8 do not overlap in a state where the headphones 1 are stored in the storage unit 210.

  Here, it is assumed that a force is applied to the ear pad 8 from the outside in a state where the headphones 1 are stored in the carrying case 100. In this case, as described above, if the opening 8A of the ear pad 8 is closed, the air in the ear pad 8 may be compressed without being discharged to the outside, and the driver unit or the like may be pressed and damaged.

  However, according to the present technology, in the plate-like body 300 provided in the storage unit 210, grooves 310 and 310 are formed at positions corresponding to the openings 8A and 8A of the ear pads 8 and 8, respectively. Thereby, even if the ear pad 8 contacts the cover part 400 located on the bottom surface of the carrying case 100, the opening 8A is not closed. In other words, the pair of openings 8 </ b> A and 8 </ b> A and the pair of grooves 310 and 310 communicate with each other via the cover 400.

  Therefore, when the ear pad 8 is pressed from the outside, the air in the ear pad 8 is discharged from the opening 8A and flows into the groove 310. Then, as shown by an arrow γ in FIG. 5, the air is discharged from the air discharge unit 320 to the outside (inside the storage unit 210) via the groove 310. In addition, since the air discharge part 320 is provided in the position where the ear pad 8 does not overlap, the ear pad 8 does not interfere with air discharge.

  Thus, even if a force is applied to the ear pad 8 from outside the carrying case 100, the air in the ear pad 8 is discharged to the outside, so that the air does not damage the driver unit or the like of the headphones 1.

  In addition, although the cover part 400 is provided on the plate-shaped body 300, since the cover part 400 is comprised with the raw material which has air permeability, the cover part 400 does not become the hindrance of discharge | emission of air. . In addition, the cover part 400 is not an essential structure on the structure of this technique.

  Since the groove 310 has a thin groove shape, the presence of the groove 310 does not cause unstable support of the ear pad by the plate-like body 300.

  The present technology is considered to be particularly effective in storing headphones having ear pads configured so that the outer peripheral surface has high airtightness, for example, noise canceling headphones. However, the present invention can also be applied to headphones that do not have a noise canceling function other than noise canceling headphones.

<2. Modification>
As mentioned above, although embodiment of this technique was described concretely, this technique is not limited to the above-mentioned embodiment, The various deformation | transformation based on the technical idea of this technique is possible.

  As described above, the air discharge portion 320 needs to be formed at a location where the ear pads 8 and 8 do not overlap in the state where the headphones 1 are accommodated in the carrying case 100. Therefore, in addition to the positions shown in FIGS. 4 and 5, for example, they may be formed at the positions shown in FIG. Even if the air discharge portion 320 is formed at the position shown in FIG. 6, the air discharge is not hindered by the presence of the ear pad 8.

  Further, the plate-like body 300 may be provided in the lid portion 220 in addition to the storage portion 210. As a result, the effect of the present technology can be achieved regardless of whether the headphones are stored in the upward or downward direction.

  In addition, the present technology can take the following configurations.
