Is to provide a case.

[0006]

[Means for Solving the Problems]

 The shield pad for a mobile phone according to the present invention (the invention according to claim 1) capable of achieving the above-mentioned object includes at least a mesh-shaped electromagnetic wave shielding cloth and a support material disposed on at least one surface of the shielding cloth. The laminated member is formed in a planar shape capable of simultaneously concealing the antenna section and the audio output section of the mobile phone, and a through-hole for audio passage is opened in a part of the support member, so that the It is attached to the telephone side of the telephone and used in a state of being interposed between the mobile telephone and the head of the user.

[0007] Here, the shield cloth in the laminated member refers to a cloth having a performance of absorbing or reflecting the energy of electromagnetic waves and preventing the transmission of the energy. In this invention, a mesh-shaped shielding cloth with air permeability (voice transmission) is used. Further, the support material of the laminated member may be made of any material that can hold the electromagnetic wave shielding cloth in a pad shape without impairing the shielding performance of the pad.

[0008] Furthermore, the planar shape forming the pad shape means that, in addition to the case where the entire pad is a perfect planar shape, the main part of the pad is planar and the remaining pad portion is three-dimensional. It refers to the shape including the case. The phrase "concealable" means that when the shield pad is attached to a mobile phone and the telephone is viewed from the side where the shield pad is attached, the antenna section and the audio output section are hidden by the presence of the pad and become invisible. State. The means for attaching the shield pad to the telephone can be adopted as long as it does not impair the shield performance of the pad and is convenient to handle, and is not particularly limited.

In such a shield pad, the laminated member has a three-layer structure of an electromagnetic wave shielding cloth and two support members respectively disposed on both front and back surfaces of the shielding cloth, and is formed by a double-sided adhesive tape. A configuration that can be attached to a mobile phone may be adopted. In this case, if the pad shape is symmetrical, the pad can be used freely without distinguishing between the front surface and the back surface. In addition, the pad can be easily attached to the mobile phone using the double-sided adhesive tape, and can be flexibly adapted to the differences in the various configurations of the mobile phone. Furthermore, in this case, from the viewpoint of considering the adhesiveness of the double-sided adhesive tape with the support material, it is preferable to use a support material having a surface state that is compatible with the double-sided adhesive tape. Desirable. For example, a support made of a cloth material or a vinyl resin can be used.

[0010] The planar shape has a shape in which an audio output unit concealing unit and an antenna unit concealing unit are connected, and the antenna unit concealing unit is turned upside down around the audio output unit concealing unit. A configuration in which the sound output unit is switched so as to be located on either the right side or the left side of the sound output unit concealing unit may be employed. In this case, whether the antenna unit is a right-handed type or a left-handed type mobile phone, it is necessary to flip the voice output unit concealment unit as the center, if necessary, to make it compatible with either type. It can be easily handled.

[0011] In addition, the double-sided pressure-sensitive adhesive tape may have a shape attached to a periphery of a through-hole for passing sound, and a hollow hole may be formed in a portion corresponding to the through-hole. Good. In this case, the pad can be easily and reliably attached to the telephone, and the double-sided adhesive tape does not hinder the voice transmission during the telephone call, thereby enabling a normal telephone call.

[0012] Further, the electromagnetic wave shielding cloth is a metal-plated woven fabric obtained by electrolessly plating copper and nickel in this order on a mesh-shaped woven material in which ultrafine synthetic fibers are woven in a state in which a gap is provided vertically and horizontally. May be adopted. In this case, even if the metal-plated fabric is copper-plated and nickel-plated, a surface resin layer made of a synthetic resin mixed with conductive particles such as carbon is further formed on the surface by coating. Good. When such an electromagnetic wave shielding cloth is used, a better electromagnetic wave shielding effect can be obtained.

On the other hand, the housing case for a mobile phone according to the present invention (the invention according to claim 6) that can achieve the above-described object houses the mobile phone with its antenna portion exposed, and then stores the mobile phone in the housing state. A case having a configuration capable of talking, wherein a case portion facing the audio output section of the housed mobile phone is provided with a case for the mobile phone according to any one of the above aspects (in any one of claims 1 to 5). The antenna unit and the audio output unit of the mobile phone during a call with the shield pad accommodated are attached so that they can be concealed at the same time.

[0014] Here, the case having a configuration in which a call can be made in the housed state means that, when the mobile phone is housed, operation buttons, a display unit, and the like on the mobile phone are visually recognized from the outside of the case. It is one that has a configuration that can be operated and that also allows calls. Therefore, at least a portion of the entire case where the operation buttons, the display unit, and the like of the accommodated mobile phone are located is formed of a transparent material. Further, the case itself is desirably configured to have the electromagnetic wave shielding performance, but may be configured to not have the shielding performance. The means for attaching the shield pad is not particularly limited as long as the pad can be securely attached to the case in a predetermined posture.For example, a sewing method, a detachable attaching method using a sheet fastener, Adhesive methods such as an adhesive can be used. When mounting the pad, the pad is mounted such that the through-hole for sound passage of the pad matches the sound output unit.

In such a housing case for a mobile phone, a configuration in which a mesh-shaped electromagnetic wave shielding cloth is stretched over at least a front surface region of the case where the communication surface side of the mobile phone is located in the entire case is adopted. Good. In this case, in addition to the electromagnetic wave shielding effect by the shield pad, the electromagnetic wave shielding effect by the electromagnetic wave shielding cloth stretched over the front area of the case can be obtained. In this case, as the electromagnetic shield cloth, in addition to a general off-the-shelf product, the same shield cloth made of the above-described metal-plated fabric can be used. Further, the electromagnetic wave shielding cloth may be stretched over the entire case including the case front region.

[0016]

[Action]

 The above-mentioned shield pad for a mobile phone is attached to the mobile phone at the time of its use, and is interposed between the antenna part and the audio output part of the mobile phone and the head (including ears) of the telephone user. Therefore, among the electromagnetic waves emitted from the antenna unit and the audio output unit of the mobile phone, the electromagnetic wave that goes to the user's head side can be absorbed or reflected by the electromagnetic wave shielding cloth in the pad and cut off. In addition, a through hole for voice passage is opened in a part of the support material, and at least a mesh-shaped shield cloth is present in the through hole, so that the call output (voice) from the voice output unit can be heard well. In addition, the electromagnetic wave shielding effect can be obtained without being impaired.

[0017] Also, in the housing shield case for a mobile phone, the telephone is so arranged that the antenna portion exposed outside the case of the mobile phone housed in the case and the audio output portion present in the case are concealed by the shield pad. And the user's head. Thus, the electromagnetic shielding effect by the shield pad as described above can be obtained even when the user talks on the telephone while accommodating the case with the antenna portion exposed outside the case. In addition, since the pad is provided with a through hole for voice transmission, it is possible to perform a good call while being stored in the case.

[0018]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described.

<< Shield Pad for Mobile Phone >> As shown in FIGS. 1 and 2, a shield pad 1 for a mobile phone according to the present invention includes an antenna section 20a provided with an antenna 21 of a mobile phone 20 and a receiving section. (Sound output speaker or sound passage hole) A pad having a rounded J-shaped planar shape that can simultaneously conceal the sound output portion 20b in which the sound output portion 22 is provided. 1a is an antenna concealing unit for concealing the antenna unit 20a, 1b is an audio output unit concealing unit for concealing the audio output unit 20b, and the dotted lines in FIG. The following shows the stitches used in the sewing process performed to laminate and integrate the constituent materials. In FIG. 2, reference numeral 23 denotes a display panel unit, 24 denotes various operation buttons, and 25 denotes a communication unit (a microphone and a voice passage hole).

As shown in FIG. 1B, the shield pad 1 includes a mesh-shaped electromagnetic wave shielding cloth 2 and supporting members 3 and 4 arranged so as to be laminated on both front and back surfaces of the shielding cloth 2, respectively. It is formed by a laminated member 5 having a three-layer structure, and is provided with a through hole 6 for sound passage in the sound output portion concealing portion 1b of the supporting members 3 and 4.

As the electromagnetic wave shielding cloth 2, a commercially available mesh-shaped shielding cloth can be used, but in this example, a synthetic fiber such as an ultrafine polyester fiber having a specific yarn diameter is specified. Copper and nickel are plated in this order by electroless plating on a woven fabric material woven so that the weave density (the level at which a predetermined mesh gap can be formed), and then the entire surface of the nickel plating film is coated. The one obtained by forming a resin layer is used.

As each of the support members 3 and 4, a sheet member formed using a vinyl chloride resin is used. It is desirable that the surface side of the supporting material be in a surface state that is at least compatible with the adhesive tape or the like, and in this example, the surface side is configured to have a relatively smooth surface state. In addition, the through holes 6 are formed at predetermined positions of the support members 3 and 4. The through-hole 6 only needs to be able to pass a call voice emitted from the voice output unit 22 of the mobile phone. In this example, an oval hole is illustrated, but the shape and size of the through-hole are described. There are no particular restrictions on the quantity, quantity, etc.

The shield pad 1 is formed by laminating support members 3, 4 on both surfaces of the electromagnetic wave shielding cloth 2 with an adhesive in such a manner that the through holes 6 are aligned with each other, and then sewn together. And finally cut into a predetermined planar shape as described above. As shown in FIG. 1B, the shield pad 1 has a portion where the through hole 6 is formed, as shown in FIG. 1B, in which the electromagnetic wave shielding cloth 2 sandwiched between the two support members 3 and 4 exists. Has become.

This shield pad 1 is used in a state of being directly attached to the mobile phone 20. In this example, as shown in FIG. 2, the pad 1 is attached to the mobile phone 20 by using a double-sided adhesive tape 7. It is configured to be attached to. Before use, the double-sided adhesive tape 7 has a structure in which release paper is provided on both sides of the adhesive layer material, and furthermore, adopts a form in which the audio output unit concealing portion 1b of the shield pad 1 is attached to the telephone 20. For this reason, it has a structure in which a hollow hole 8 having a shape, a size, and the like corresponding to the through hole 6 of the shield pad 1 is formed in the center portion thereof.

The mobile phone shield pad 1 having such a configuration is used as follows.

First, the shield pad 1 is attached to the mobile phone 20 via the double-sided adhesive tape 7 in such a manner that the antenna section 20a and the audio output section 20b can be simultaneously concealed. In this example, as shown in FIG. 2 and FIG. 3, the periphery of the through hole 6 in the audio output unit concealing unit 1b of the shield pad 1 is placed in such a posture that the antenna unit concealing unit 1a is located in the antenna unit 20a. In this way, it is attached around the audio output unit 20b of the telephone 20. That is, after the double-sided adhesive tape 7 is attached to the shield pad 1 in such a manner that the hole 8 is aligned with the through hole 6 of the pad, the shield pad 1 with the tape 7 attached is removed. This is performed by attaching the telephone to the main body of the telephone 20 in a state where the telephone receiver 22 is located inside the through hole 6. Note that the shield pad 1 is attached to the telephone 20 by attaching the double-sided adhesive tape 7 to the audio output unit 20b of the telephone 20 and then attaching the tape 7 to the telephone 20 in a state where the tape 7 is attached. Needless to say, the procedure of attaching the shield pad 1 may be performed.

Thus, the shield pad 1 conceals the antenna section 20a of the mobile phone 20 by the antenna section concealing section 1a and simultaneously conceals the audio output section 20b by the audio output section concealing section 1b. It is attached to the mobile phone 20. When a call is made using the mobile phone 20 to which the shield pad 1 is attached, as shown in FIG. 4, the voice output unit 22 of the telephone 20 is pushed into the ear 30 of the telephone user. The user uses the telephone 20 while holding it in such a state. At this time, the shield pad 1 is interposed between the mobile phone 20 and the head 31 of the user. For this reason, the electromagnetic waves emitted from the antenna 21 and the audio output section toward the ears 30 and the head 31 of the telephone user during a call are reflected or absorbed by the electromagnetic wave shielding cloth 2 of the shield pad 1 and cut off. Will not reach the head. As a result, there is no possibility that the electromagnetic waves of the mobile phone 20 are absorbed in the brain.

Also, in this embodiment, the case where the shield pad 1 is used for the mobile phone 20 of the type in which the antenna 21 is disposed on the right side of the phone main body (FIG. 3) has been described. As shown in FIG. 5, the front and back surfaces of the shield pad 1 are turned upside down around the audio output unit concealing unit 1b so that the antenna 21 is disposed on the left side of the telephone body. The same can be used for the mobile phone 200.

In other words, in this case, the shield pad 1 is formed of the same support material on the front and back surfaces, and the antenna is turned upside down when the front and back surfaces are turned around the audio output unit concealing portion 1b. The antenna concealing section 1a is switched over so that the antenna concealing section 1a is switched to be located on either the right side or the left side of the audio output section concealing section 1b. Since the antenna 21 is located on the left side of the concealing portion 1b, as shown in FIG. 5, the antenna 21 can be used by being attached to the mobile phone 200 disposed on the left side. The method and procedure for attaching the shield pad 1 to the telephone 200 at this time are the same as those in the above-described example. Also in this case, an electromagnetic wave shielding effect by the shield pad 1 can be obtained as in the case of the above-described example.

FIG. 6 shows an example of the shield pad 1 used for a portable telephone 210 of a type in which the antenna 21 is arranged at the center of the telephone main body. This shield pad 1 has the same configuration as the pad 1 of the above-described example, except that its planar shape is an inverted T-shape having a rounded outline.

In the shield pad 1, the antenna unit concealing unit 1a and the audio output unit concealing unit 1b are continuously arranged on the same straight line (L), and have a symmetrical plane shape with the straight line L as a symmetric axis. ing. For this reason, it is possible to use either the front or back surface when using it. Then, it is used by being attached to the mobile phone 210 using the double-sided adhesive tape 7.

In the above-described embodiment, the shield pad 1 formed of the laminated member 5 having the three-layer structure has been described as an example. As the laminated member 5, one support member is laminated on one surface of the electromagnetic wave shielding cloth 2. A laminated member having a two-layer structure arranged as described above may be used, or a laminated member having a laminated structure of four or more layers may be used. The support itself may have a multilayer structure.

The shield pad 1 is used in a mobile phone having a fixed antenna 21 and in a mobile phone having a telescopic antenna 21 in a state where the antenna 21 is not pulled out from the main body and extended. ), A good electromagnetic wave shielding effect can be obtained. Incidentally, even when the telescoping antenna 21 is pulled out from the telephone main body and used in a state where the upper part of the antenna protrudes from the shield pad 1, the antenna 21 in the mobile telephone is mainly from the base (root) side. Since it is pointed out that electromagnetic waves are being generated, the shield pad 1 can at least provide an effect of shielding electromagnetic waves generated from the base side of the antenna 21. However, if even a small amount of electromagnetic waves from the extracted portion of the extendable antenna 21 is recognized (although no substantial change in radio sensitivity due to the extraction of the antenna can be obtained), the antenna 21 is removed. It is desirable to use it in a state where it is not pulled out (contained state). The above situation is the same in the case of a mobile phone housing case (50) having a shield pad (10) described later.

<< Accommodation Case for Cellular Phone >> The accommodating case 50 for a cellular phone of the present invention is a case in which a cellular phone can be accommodated with its antenna portion exposed, and a conversation can be performed in the accommodated state. As shown in FIG. 7, a case front part 51a, a side part 51b, and a back part 51c for forming a housing part 51 for housing the mobile phone 20, and a case extending from an upper part of the case front part 51a. The main part is constituted by a lid part 52 and a mobile phone shield pad 10 attached to a part corresponding to both the upper part of the case front part and the lower part of the case lid part 52.

The case front portion 51 a has at least a transparent resin film 60 in a surface area of the front panel 51 a where the display panel 23 and the operation button 24 of the mobile phone housed in the housing 51 are located. The region is formed of another case constituent member 61 (for example, synthetic leather, cloth material, or the like). Further, the electromagnetic wave shielding cloth 2 described above is entirely stretched over the entire case accommodating portion 51 and the lid portion 52. Further, the transparent resin film 60 in the area where the communication section 25 which is the voice input section of the mobile phone is located, and the case component 61 in the area where the receiver section 22 which is the voice output section are located, are provided with voice during the call. A plurality of opening holes 62 and 63 are formed in order to make the holes easily pass through the members 60 and 61. The openings 62 and 63 are not provided in the shield cloth 2. Reference numeral 64 in FIG. 7 is an edge member.

The cover 52 has a constricted portion near the antenna 21 to avoid hitting the antenna 21 when the mobile phone is stored. It is bent to the side 51c and is detachably fixed to the rear surface 51c. Further, in the housing case 50, a mounting piece 53 for mounting the case 50 to the body of a telephone user while being sandwiched between pants belts or the like is provided on the back surface 50c (FIG. 9).

The shield pad 10 for a mobile phone basically has the same configuration as the shield pad 1 described above, except that its planar shape is slightly changed for convenience of attachment to the housing case 50. The shield pad 10 can simultaneously conceal the antenna 21 and the receiver 22 of the mobile phone that is talking while the shield pad is stored in a case portion facing the receiver 22 of the stored mobile phone 20. It is attached in a state (posture) (FIG. 8). In this example, the antenna concealing portion 10a of the pad 10 is exposed from the side of the case lid 52 on the back side of the region where the opening 63 is provided in the case front 51a. The sound output section concealing section 10b of the pad 10 is sewn and fixed. At this time, the shield pad 10 is attached in such a state that the through hole 6 for sound transmission opened in the sound output portion concealing portion 10b substantially matches the opening 63 provided on the case side.

The housing case 50 for a mobile phone having such a shield pad 10 is used as follows.

First, as shown in FIG. 8, the mobile phone 20 is put in the accommodating portion 51 of the mobile phone case 50. At this time, the mobile phone is accommodated in such a manner that the communication surface is located on the case front portion 51a side, and the antenna concealing portion 10a of the shield pad 10 is kept in a state of protruding outside the case. After the housing, the case lid 52 is bent toward the case back 50b so as to get over the upper part of the mobile phone 20 and fixed by a predetermined fixing means (FIG. 9). As a result, the mobile phone 20 is housed and fixed in the housing portion 51 with only the antenna 21 and a part of the upper part being exposed outside the case. The exposed antenna 21 is concealed by the antenna concealing portion 10a of the shield pad 10.

When the mobile phone 20 is accommodated in this way, as shown in FIG. 8, the display panel 23 and the operation buttons 24 of the mobile phone are formed of the transparent film member 60 of the case front 51a. It will be located in the area. In addition, the receiving section 22 and the talking section 25 of the telephone 20 are located in a state where they are substantially aligned with the openings 63 and 62 of the case 50. As a result, the display panel 23 and the operation buttons 24 can be viewed from the outside of the case 50 through the transparent film member 60, and can be pressed from above the transparent film member 60 Can be operated from outside. In addition, the voice of the call is transmitted well. Therefore, according to the storage case 50, the mobile phone 20 can easily perform necessary operations and calls while being stored in the case 50.

During a call, as shown in FIG. 9, the front side of the case 50 accommodating the mobile phone 20 is used by pressing it slightly against the ear 30 of the telephone user.

At this time, the shield pad 10 is interposed between the mobile phone 20 and the user's head 31 in such a state that the antenna 21 and the receiver 22 of the phone 20 are simultaneously concealed. . For this reason, the electromagnetic waves emitted from the antenna 21 or the earpiece unit 22 during the telephone call and directed to the ear part 30 or the head 31 of the telephone user are reflected or absorbed by the electromagnetic wave shielding cloth 2 of the shield pad 10 and cut off. As a result, it will not reach the head.

Further, in this storage case 50, since the electromagnetic wave shielding cloth 2 exists from the case front face 50 a to the lid 52, the shielding cloth 2 is placed between the mobile phone 20 and the user's head 31. Will naturally intervene. Therefore, the electromagnetic wave emitted from the mobile phone 20 is also blocked by the shield cloth 2 on the case 50 side, and does not reach the head 30 or the like.

In this embodiment, the case where the shield pad 10 is attached to the inside of the housing case 50 is exemplified, but the shield pad 10 may be attached to the outside (surface) of the case 50. When the mobile phone is of a type having an antenna arranged on the left side, the shield pad 10 may be attached with the antenna concealing portion 10a of the pad 10 exposed on the left side of the case. If the telephone has a centrally located antenna, the antenna may be mounted such that the antenna concealing portion 10a is exposed at the center of the case.

Also, in this embodiment, the electromagnetic wave shielding cloth 2 has been described as having a configuration in which the electromagnetic shielding cloth 2 is stretched over the entire housing case 50. The shield cloth 2 may not be provided at all. Further, the overall shape, dimensions, material, and the like of the storage case 50 can be appropriately changed.
