Description

[Technical Field]

[0001] The present invention relates to a sound leakage suppression mask that suppresses the sound emitted by a user from leaking to the outside. [Background technology]

[0002] Patent Document 1 discloses a mask with a sound leakage suppression function that suppresses the leakage of a user's voice to the outside. This mask has a mask body that covers the user's mouth, and the mask body is provided with a sound-absorbing material that absorbs the user's voice. The mask body also has a built-in microphone that detects the user's voice, allowing the user to talk to others using the microphone. With the mask of Patent Document 1, when the user talks to others, the user's voice is absorbed by the sound-absorbing material, making it possible to suppress the voice from leaking to the outside.

[0003] The mask in Patent Document 1 is also provided with ear pad-type speakers that are attached to the user's ears. These ear pad-type speakers are attached to the mask body via a support member. This allows the user to hear the other person's voice through the speakers when talking to them. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 5896548 Summary of the Invention [Problem to be solved by the invention]

[0005] Here, it is conceivable to attach wired earphones or headphones to the mask body instead of the earpad-type speakers in the mask of Patent Document 1. However, in that case, it is thought that the earphones or headphones would get in the way when putting the mask body on the face, making them difficult to handle.

[0006] The present invention has been made in view of the above circumstances, and a main object of the present invention is to make it easier to handle a sound leakage suppression mask equipped with earphones or headphones. [Means for solving the problem]

[0007] In order to achieve the above object, the sound leakage suppression mask of the present invention comprises: A sound leakage suppression mask that suppresses the sound emitted by a user from leaking to the outside, a mask body that covers the user's mouth; and wired earphones or headphones attached to the mask body, The mask body includes: a front plate portion that forms the front surface of the mask body; a peripheral wall portion extending rearward from the peripheral edge side of the front plate portion and forming a peripheral surface of the mask body; It has The peripheral wall portion is provided with a first terminal portion, A second terminal portion is provided on the cable of the earphone or the headphone, The second terminal portion is made of a magnetic terminal and is connected to the first terminal portion by being attracted to the first terminal portion by magnetic force. [Effects of the Invention]

[0008] According to the present invention, a first terminal is provided on the peripheral wall of the mask body, and a second terminal is provided on the cable of earphones or headphones (hereinafter referred to as earphones, etc.). The second terminal is a magnetic terminal and is connected to the first terminal by being attracted to it by magnetic force. This allows the earphones, etc. to be detachably attached to the mask body. With this configuration, when the user puts the mask body on their face, they can remove the earphones, etc. from the mask body, and then attach the earphones, etc. to the mask body after putting the mask body on their face. This prevents the earphones, etc. from getting in the way when putting the mask body on their face.

[0009] However, when the mask body is worn on the face, it is considered difficult to visually recognize the first terminal portion of the mask body. Therefore, after wearing the mask body on the face, when connecting the second terminal portion of earphones or the like to the first terminal portion, the connection work is considered difficult. In this regard, in the present invention, when the second terminal portion is brought close to the first terminal portion during the connection work, the second terminal portion is attracted to the first terminal portion by magnetic force and connected. Therefore, the connection work can be easily performed even when the mask body is worn on the face.

[0010] As described above, according to the present invention, it is possible to make it easier to handle a sound leakage suppression mask equipped with earphones or headphones. [Brief explanation of the drawings]

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A sound leakage suppression mask according to one embodiment of the present invention will now be described with reference to the drawings.

[0013] 1, the sound leakage reduction mask 10 includes a mask body 11 that covers the user's mouth, a band 12 for attaching the mask body 11 to the user's face, and a pair of wired earphones 13 that are attached to the user's ears. The mask body 11 has a horizontally elongated shape that extends in the left-right direction, and covers only the user's mouth but not the nose (see also FIG. 8).

[0014] The bands 12 are string-like or belt-like and are attached to both left and right ends of the mask body 11. The bands 12 are hung around the user's ears or the back of the head, thereby attaching the mask body 11 to the user's face. The bands 12 may be hung around both the user's ears and the back of the head. In the following description, the front-rear direction, left-right direction, and up-down direction are defined based on the state in which the mask body 11 is worn on the user's face.

[0015] As shown in FIGS. 1 to 3, the mask body 11 has a base portion 15 that forms the front surface of the mask body 11, and a face support portion 16 that is provided behind the base portion 15 and that fits closely to the user's face. The base portion 15 is made of a resin material. As shown in FIG. 4, the base portion 15 has a front plate portion 17 that forms the front surface of the mask body 11, and a ring-shaped surrounding wall portion 18 that extends rearward from the periphery of the front plate portion 17 (see also FIG. 9). The base portion 15 has a bilaterally symmetrical configuration.

[0016] The front plate 17 is formed in the shape of an oval plate extending in the left-right direction. More specifically, both left-right ends of the front plate 17 are slightly curved rearward. The periphery of the front plate 17 extends outward beyond the surrounding wall 18, and this extending portion forms an annular flange 19. Both left-right ends of the flange 19 are provided with mounting holes 21 as mounting portions for attaching the band 12.

[0017] The surrounding wall 18 is formed in an oval ring shape extending in the left-right direction. The surrounding wall 18 has an upper wall 18a that forms the upper surface of the surrounding wall 18, a lower wall 18b that forms the lower surface of the surrounding wall 18, and a pair of left and right side wall portions 18c that connect the upper wall portion 18a and the lower wall portion 18b in an arc shape. The lower wall portion 18b has a notch 22 (see also FIG. 5(b)) that is cut out over the entire left-right area thereof.

[0018] The base 15 has a plurality of spaces 23 to 26 defined by partition walls 27 to 29 within the interior space surrounded by the peripheral wall 18. These spaces 23 to 26 are open to the rear. The spaces 23 to 26 include a first space 23 located in the center of the base 15 in the left-right direction, a pair of second spaces 24 and 25 located on either side of the first space 23 in the left-right direction, and a third space 26 located below the first space 23.

[0019] The first space 23 is adjacent to each of the second spaces 24, 25 in the left-right direction, and adjacent to the third space 26 in the up-down direction. Each of the second spaces 24, 25 extends downward from the first space 23, and the extending portion is adjacent to the third space 26 in the left-right direction. The third space 26 is an elongated space extending in the left-right direction, and its length in the left-right direction is the same as that of the first space 23.

[0020] The first space 23 is a space that opens toward the user's mouth. The first space 23 is designed to receive the voice uttered by the user. An uneven region 61 formed in an uneven shape is provided on the bottom surface of the first space 23. The uneven region 61 is made of a gypton structure. The voice of the user that enters the first space 23 is absorbed by the uneven region 61. Although not shown, a sound-absorbing material is provided in the first space 23, and the user's voice is also absorbed by this sound-absorbing material. The user's exhaled air that enters the first space 23 is led to the outside of the mask body 11 through an outlet path 63 provided in the base portion 15.

[0021] The base portion 15 is provided with a plurality of partition walls 27-29 that separate the spaces 23-26. These partition walls 27-29 extend rearward from the front plate portion 17. The partition walls 27-29 include a partition wall 27 that separates the first space 23 from the second space 24, a partition wall 28 that separates the first space 23 from the second space 25, and a partition wall 29 that separates the first space 23 from the third space 26. Each of the partition walls 27, 28 extends in the vertical direction, with its upper end connected to the upper wall portion 18a of the surrounding wall portion 18 and its lower end connected to the lower wall portion 18b of the surrounding wall portion 18. The partition wall 29 extends in the horizontal direction, with both ends connected to the respective partition walls 27, 28.

[0022] Each of the partition walls 27, 28 has an extending portion 27a, 28a extending downward further than the partition wall 29. The third space 26 is separated from the second space 24 by the extending portion 27a of the partition wall 27, and is separated from the second space 25 by the extending portion 28a of the partition wall 28.

[0023] 5(a) and 5(b), the base portion 15 is provided with a plurality of lid portions 31 that close the openings of the second spaces 24, 25, respectively, and a cover portion 32 that covers the third space 26 from the outside. The lid portions 31 and the cover portion 32 are made of a resin material and are detachably attached to the base portion 15.

[0024] The cover portion 32 has an L-shaped cross section extending in the left-right direction and includes a rear plate portion 32a that covers the third space 26 from the rear and a lower plate portion 32b that covers the third space 26 from below. The lower plate portion 32b is disposed in a cutout portion 22 formed in the lower wall portion 18b of the surrounding wall portion 18. In this case, the surrounding wall portion 18 and the lower plate portion 32b form an annular peripheral wall portion 37 that extends rearward from the front plate portion 17 of the base portion 15. The peripheral wall portion 37 forms the peripheral surface of the base portion 15. In this case, the lower plate portion 32b and the lower wall portion 18b form a lower wall portion 37a that forms the lower surface of the peripheral wall portion 37. The lower wall portion 37a faces the partition wall 29 across the third space 26.

[0025] The base portion 15 is provided with a plurality of protrusions 35a to 35c that are used when attaching the face rest portion 16. The protrusions 35a to 35c protrude rearward and extend along the surrounding wall portion 18. Of the protrusions 35a to 35c, the protrusion 35a is provided on the upper wall portion 18a of the surrounding wall portion 18, the protrusion 35b is provided on the lid portion 31, and the protrusion 35c is provided on the rear plate portion 32a of the cover portion 32.

[0026] Next, we will explain the face support portion 16. As shown in Figures 6(a) and (b), the face support portion 16 has an annular portion 41 formed in an annular shape and a wall portion 42 provided on the inside surrounded by the annular portion 41. The face support portion 16 is made of a rubber material, for example, silicone rubber.

[0027] The annular portion 41 is formed in an oval ring shape that is long in the left-right direction. The annular portion 41 is the portion that fits tightly against the user's face around the user's mouth. Therefore, the user's mouth is accommodated inside the area surrounded by the annular portion 41. A groove-shaped annular space 44 that opens forward is formed in the annular portion 41. Although not shown in the figure, an annular space 44 is provided with an annular sound-absorbing material.

[0028] A plurality of slit grooves 47 that open forward are formed on the outer periphery of the annular portion 41. The protrusions 35a to 35c of the base portion 15 are fitted into these slit grooves 47. In this way, the face support portion 16 is detachably attached to the base portion 15.

[0029] The wall portion 42 is provided at the front end of the annular portion 41 so as to close an inner opening surrounded by the annular portion 41. A plurality of slit holes 45 are formed in the wall portion 42, penetrating the wall portion 42 in the thickness direction. The first space 23 of the base portion 15 opens toward the user's mouth through these slit holes 45 (and thus through the inner opening surrounded by the annular portion 41).

[0030] The annular portion 41 of the face support portion 16 is provided with a plate-shaped extension portion 51 that extends forward from its upper edge. The upper surface of the extension portion 51 is continuous with the upper surface of the annular portion 41 in the front-to-rear direction. In this case, the upper surface of the face support portion 16 is formed by the upper surfaces of the extension portion 51 and the annular portion 41. The upper surface of the face support portion 16 corresponds to the upper surface of the mask body 11.

[0031] The extension portion 51 has a length in the front-rear direction (in other words, an extension length) that is approximately the same as the length in the front-rear direction of the annular portion 41. Moreover, the extension portion 51 extends in the left-right direction along the upper edge of the annular portion 41, and the length in the left-right direction is at least twice the length in the front-rear direction.

[0032] As shown in FIGS. 2 and 3, the extension 51 is superimposed on the upper surface of the peripheral wall 37 of the base 15, more specifically, on the upper surface of the upper wall 18a of the peripheral wall 18 (see FIGS. 4 and 5(a)). In the peripheral wall 18, the upper surface of the upper wall 18a is located lower than the upper ends of the side wall portions 18c. As a result, an arrangement recess 52 in which the extension 51 is disposed is formed on the upper surface side of the upper wall 18a. The extension 51 is disposed in this arrangement recess 52, and in this disposed state, the upper surface of the extension 51 is smoothly continuous with the outer surfaces of the side wall portions 18c of the peripheral wall 18. Furthermore, the front end of the extension 51 is adjacent to or abuts against the flange 19 of the base 15.

[0033] On the underside of the extension portion 51, protrusions 53 are provided on both ends in the left-right direction of the extension portion 51. Meanwhile, in the upper wall portion 18a, a plurality of holes 54 (see FIGS. 4 and 5(a)) are provided corresponding to the protrusions 53. The protrusions 53 of the extension portion 51 are fitted into the holes 54 of the upper wall portion 18a, respectively. In this way, the extension portion 51 is detachably attached to the upper wall portion 18a.

[0034] 2, 3, and 6, a downwardly recessed recess 55 is formed in a portion of the upper surface of the face support portion 16 that is located directly below the user's nose. The recessed portion 55 is a groove extending in the front-to-rear direction, and is formed across the upper surface of the annular portion 41 and the upper surface of the extension portion 51. This recessed portion 55 makes it possible to reduce the degree to which the upper surface of the face support portion 16 interferes with the user's nose when the user wears the mask body 11 on their face.

[0035] 7, the upper surface of the face support 16 includes a concave curved surface portion 56 formed to be concave downward when viewed from the front-to-rear direction, and a pair of convex curved surface portions 57 formed to be convex upward on both left and right sides of the concave curved surface portion 56. The concave curved surface portion 56 is smoothly continuous with each of the pair of convex curved surface portions 57. In this configuration, if the uppermost portion of the convex curved surface portion 57 is defined as the uppermost portion 57a, the downwardly recessed portion between the uppermost portions 57a of the convex curved surface portions 57 forms the concave portion 55.

[0036] To minimize interference with the user's nose, the width W of the recessed portion 55 is preferably 15 to 60 mm, and the depth D of the recessed portion 55 is preferably 2 to 20 mm. The width W of the recessed portion 55 corresponds to the distance between the uppermost portions 57a of the convex curved surface portions 57. If the lowest point of the concave curved surface portion 56 is defined as the lowest portion 56a, the depth D of the recessed portion 55 corresponds to the vertical distance from the lowest portion 56a to the uppermost portion 57a ​​of the convex curved surface portion 57.

[0037] The recessed portion 55 is formed by bending the extending portion 51. Therefore, the lower surface of the extending portion 51 has a curved shape corresponding to the recessed portion 55. In addition, the upper surface of the upper wall portion 18a of the base portion 15, on which the extending portion 51 is placed, also has a curved shape corresponding to the recessed portion 55. This makes it possible for the extending portion 51, on which the recessed portion 55 is formed, to be placed stably on the upper surface of the upper wall portion 18a.

[0038] 2 to 5 and 7, a downwardly recessed portion 65 is formed on the upper end side of the flange portion 19 of the base portion 15. The recessed portion 65 is formed at the same position as the recessed portion 55 in the left-right direction. The recessed portion 65 has a curved bottom surface. The width of the recessed portion 65 is smaller than the width W of the recessed portion 55.

[0039] Next, the electrical components provided in the mask body 11 will be described with reference to Fig. 9. In Fig. 9, the mask body 11 is shown with the lid portions 31 and cover portions 32 removed.

[0040] As shown in FIG. 9 , the base portion 15 of the mask body 11 is provided with a plurality of circuit boards 71 ​​and 72 and a battery 73 as electrical components. The circuit board 71 is housed in the second space 24 of the base portion 15, the circuit board 72 is housed in the third space 26, and the battery 73 is housed in the second space 25. The circuit board 71 is connected to the circuit board 72 via a wiring 75. The wiring 75 extends between the second space 24 and the third space 26 through a hole 76 formed in the extension portion 27a of the partition wall 27. The battery 73 is connected to the circuit board 72 via a wiring 78. The wiring 78 extends between the second space 25 and the third space 26 through a hole 79 formed in the extension portion 28a of the partition wall 28. The circuit board 71 corresponds to the "second board" and the circuit board 72 corresponds to the "first board."

[0041] The substrate 72 is formed in the shape of a long plate extending in the left-right direction. The substrate 72 is disposed with both plate surfaces facing up and down. A microphone 81 is mounted on the upper plate surface 72a of the substrate 72, and a plurality of terminals 82, 83 are mounted on the lower plate surface 72b. In this case, the microphone 81 and the terminals 82, 83 are both housed in the third space 26.

[0042] The microphone 81 detects the voice uttered by the user. The microphone 81 is formed in a cylindrical shape extending in the vertical direction. The microphone 81 is disposed in the center of the substrate 72 in the longitudinal direction.

[0043] As shown in Fig. 5(a), the partition wall 29 is provided with a sound guide portion 86 that guides the user's sound that has entered the first space 23 to the microphone 81. The sound guide portion 86 is attached to a notch 88 (see Figs. 4 and 9) formed in the partition wall 29. The notch 88 is a communication portion that connects the first space 23 and the third space 26, and is formed in a position aligned vertically with the microphone 81. Note that Fig. 9 shows a state in which the sound guide portion 86 has been removed.

[0044] The sound guiding portion 86 is made of a rubber material. As shown in Figures 10(a) and (b), the sound guiding portion 86 has an attachment portion 86a that is attached to the cutout portion 88 so as to cover the cutout portion 88, and a tubular portion 86b that extends cylindrically downward from the attachment portion 86a (i.e., toward the microphone 81). A groove portion 86c is formed on the circumferential surface of the attachment portion 86a. The attachment portion 86a is attached by fitting the edge portion of the partition wall 29 on the cutout portion 88 side into the groove portion 86c.

[0045] The microphone 81 is inserted into the cylindrical portion 86b from below. The microphone 81 is fitted inside the cylindrical portion 86b. The sound guide portion 86 is also formed with a sound passage portion 86d that opens into the first space 23 and extends to the inside of the cylindrical portion 86b. The user's sound is guided from the first space 23 to the microphone 81 through the sound passage portion 86d.

[0046] As shown in FIGS. 9, 11, and 12, the multiple terminals 82, 83 include a pair of earphone terminals 82 to which earphones 13 can be connected, and a charging terminal 83 to which an external power source can be connected. These terminals 82, 83 are provided on the underside of the peripheral wall 37. The charging terminal 83 is located in the center of the mask body 11 in the left-right direction. The pair of earphone terminals 82 are located on both sides of the charging terminal 83 in the left-right direction. Therefore, in this case, these three terminals 82, 83 are arranged side by side in the left-right direction. The pair of earphone terminals 82 each correspond to a "first terminal portion," and the charging terminal 83 corresponds to a "third terminal portion."

[0047] A plurality of openings 92 that expose each earphone terminal 82 downward and an opening 93 that exposes charging terminal 83 downward are formed in bottom wall 37a of peripheral wall 37. These openings 92, 93 are formed in bottom plate 32b of cover 32 that constitutes bottom wall 37a.

[0048] An earphone 13 can be connected to each earphone terminal 82 through the opening 92. Each earphone 13 is a mono-ear earphone worn on one ear of the user. Therefore, each earphone 13 has only one speaker unit 13c (see FIG. 1) that is worn on the ear and outputs sound. The cable 13a of each earphone 13 is provided with a terminal 13b that can be connected to the earphone terminal 82. The terminal 13b is a magnetic terminal that includes a magnet. The terminal 13b is attracted to the earphone terminal 82 by magnetic force, and is connected to the earphone terminal 82 by this attraction. Note that each earphone 13 has the same configuration, which allows it to be connected to any of the earphone terminals 82. The terminal 13b corresponds to the "second terminal unit."

[0049] Terminal 13b of earphone 13 is connected to earphone terminal 82 from below. In this connected state, cable 13a of earphone 13 extends outward in the left-right direction from terminal 13b. Furthermore, when terminal 13b of earphone 13 is connected to earphone terminal 82, terminal 13b is covered from the front by flange portion 19 of base portion 15. More specifically, in this case, terminal 13b is entirely covered from the front by flange portion 19. However, a configuration in which only a portion of terminal 13b is covered from the front by flange portion 19 may also be used.

[0050] An external power source can be connected to the charging terminal 83 through an opening 93. The external power source is a commercial power source, such as a wall outlet. The charging terminal 83 can be connected to an external power source (more specifically, an outlet) via a connection cable 94. This allows power to be supplied from the external power source to the battery 73, thereby charging the battery 73. The microphone 81 and earphone 13 are also driven by the power from the battery 73.

[0051] When a user wears the sound leakage reduction mask 10 on their face and wants to talk with others, the conversation is carried out using, for example, a smartphone. In this case, when the user's voice is detected by the microphone 81, the voice is wirelessly transmitted from a transmitting unit (not shown) provided on the substrate 71 to the user's smartphone. The voice is then transmitted from the smartphone to the other person. Furthermore, when the other person's voice is transmitted to the user's smartphone, the voice is wirelessly transmitted from the smartphone to the mask body 11. When this voice is received by a receiving unit (not shown) provided on the substrate 71, the voice is output from the speaker unit 13c of the earphone 13. This makes it possible to hear the other person's voice.

[0052] According to the configuration of this embodiment described above in detail, the following excellent effects can be obtained.

[0053] The mask body 11 has a front plate 17 that forms the front surface of the mask body 11, and a peripheral wall 37 that extends rearward from the peripheral edge of the front plate 17 and forms the peripheral surface of the mask body 11. Earphone terminals 82 are provided on the peripheral wall 37 of the mask body 11, and a magnetic terminal 13b is provided on the cable 13a of the earphones 13. The terminals 13b of the earphones 13 are connected to the terminals 82 by being attracted to the earphone terminals 82 by magnetic force. This allows the earphones 13 to be detachably attached to the mask body 11. With this configuration, when wearing the mask body 11 on the face, the user can remove the earphones 13 from the mask body 11, and then attach the earphones 13 to the mask body 11 after wearing the mask body 11 on the face. This prevents the earphones 13 from getting in the way when wearing the mask body 11 on the face.

[0054] Incidentally, when mask body 11 is worn on the face, it is thought that it would be difficult to visually confirm earphone terminal 82 of mask body 11. Therefore, after wearing mask body 11 on the face, it is thought that the connection work would be difficult when connecting terminal 13b of earphone 13 to earphone terminal 82. In this regard, with the above configuration, when connecting, if terminal 13b of earphone 13 is brought close to earphone terminal 82, terminal 13b is attracted to earphone terminal 82 by magnetic force and connected. Therefore, the connection work can be easily performed even when mask body 11 is worn on the face.

[0055] As described above, the sound leakage suppression mask 10 equipped with the earphones 13 can be easily handled.

[0056] For example, if the earphone terminal 82 is provided on the upper surface of the mask body 11, the cable 13a of the earphone 13 connected to the earphone terminal 82 may get in the way by passing in front of the user's face. In this regard, in the above embodiment, the earphone terminal 82 is provided on the lower surface of the peripheral wall 37 of the mask body 11, which prevents such inconvenience from occurring.

[0057] Additionally, the underside of mask body 11 is particularly difficult to see when mask body 11 is attached to the face. However, because terminal 13b of earphone 13 is connected to earphone terminal 82 by magnetic attraction, earphone 13 can be easily connected to mask body 11 even with this configuration.

[0058] When the terminal 13b of the earphone 13 is connected to the earphone terminal 82 of the mask body 11, the terminal 13b is covered from the front by the flange portion 19 of the front plate portion 17. More specifically, the entire terminal 13b is covered from the front by the flange portion 19. This prevents the terminal 13b from spoiling the appearance of the mask body 11.

[0059] A pair of single-ear earphones 13 are provided, each with a magnetic terminal 13b. The peripheral wall 37 of the mask body 11 is also provided with a plurality of earphone terminals 82 to which the terminals 13b are connected. With this configuration, when wearing only one earphone 13, one earphone 13 can be worn in that ear, and the other earphone 13 can be removed from the mask body 11. This prevents the unused earphone 13 from getting in the way when wearing only one ear.

[0060] When a pair of earphones 13 is worn on each ear, the terminals 13b of each earphone 13 are connected to the earphone terminals 82 on the mask body 11. In this case, the terminals 13b of each earphone 13 are magnetic terminals, which makes it easy to connect each earphone 13.

[0061] A substrate 72 on which a microphone 81 that detects the user's voice is mounted is provided inside the area surrounded by the peripheral wall 37 of the mask body 11, and earphone terminals 82 are mounted on the substrate 72. In this case, by consolidating the microphone 81 and the earphone terminals 82 on the common substrate 72, the configuration can be simplified.

[0062] In addition to the earphone terminals 82, a charging terminal 83 that can be connected to an external power source is provided on the underside of the peripheral wall 37 of the mask body 11. In this case, by consolidating the three externally connectable terminals 82, 83 on the underside of the peripheral wall 37, usability can be improved.

[0063] Furthermore, since each earphone terminal 82 is arranged on both sides of the charging terminal 83 in the left-right direction, when an external power source is connected to the charging terminal 83 via the connection cable 94, it is possible to prevent the earphone 13 connected to the earphone terminal 82 from interfering with the connection cable 94.

[0064] Furthermore, since the charging terminal 83 is mounted on the substrate 72, the microphone 81, the earphone terminals 82, and the charging terminal 83 can be integrated onto the common substrate 72. This further simplifies the configuration.

[0065] Inside the area surrounded by the peripheral wall portion 37, a board 71 is provided on one side of the board 72 in the left-right direction, and a battery 73 is provided on the other side of the board 72 in the left-right direction. The board 72 connects the board 71 and the battery 73 via wires 75 and 78. In this case, the board 72 serves to connect the board 71 and the battery 73 in addition to collectively arranging the microphone 81 and the terminals 82 and 83. This allows the board 72 to have multiple functions.

[0066] The present invention is not limited to the above-described embodiment, and may be implemented, for example, as follows.

[0067] In the above embodiment, the band 12 is used as the attachment part for attaching the mask body 11 to the face, but the attachment part does not necessarily have to be the band 12. For example, a mask-type wearable mask may be used as the attachment part. The wearable mask has a cover mask that covers the mask body 11 from the outside and a pair of left and right ear loops attached to the cover mask. With this wearable mask, the ear loops are hung over the user's ears, and the mask body 11 is pressed against the face by the cover mask. This makes it possible to hold (wear) the mask body 11 on the user's face.

[0068] In the above embodiment, a pair of single-ear earphones was provided as the earphones 13, but a single double-ear earphone may also be provided as the earphones. In this case, the mask body 11 only needs to be provided with one earphone terminal 82.

[0069] A configuration may be adopted in which headphones are provided instead of the earphones 13. In this case, too, the terminal of the headphone cable (corresponding to the second terminal portion) may be a magnetic terminal.

[0070] In the above embodiment, the earphone terminal 82 is provided on the lower surface of the peripheral wall 37 of the mask body 11, but the earphone terminal 82 may be provided on the side or upper surface of the peripheral wall 37.

[0071] In the above embodiment, earphone terminal 82 is mounted on the same substrate 72 as microphone 81, but for example, a separate substrate for earphone terminal 82 may be provided and earphone terminal 82 may be mounted on that substrate. Also, earphone terminal 82 does not necessarily have to be mounted on the substrate, and may be provided independently. [Explanation of symbols]
