[0009] With reference to the drawings, embodiments of an ear device 100 and a system including the ear device 100 according to the present invention will be described. The following embodiments are subject to various limitations that are technically preferable for implementing the present invention, but the scope of the present invention is not limited to the following embodiments and illustrated examples. In the following first and second embodiments, the configuration for fastening the ear device 100 to the ear E differs, but the configuration of the ear device 100 is the same in both embodiments. For this reason, the ear device 100 will be described first as a configuration common to the first and second embodiments. Note that, hereinafter, the left ear will be referred to as the "left ear E1" and the right ear will be referred to as the "right ear E2." Furthermore, when simply referring to "ear E," there is no particular distinction between the left and right ears, and both the "left ear E1" and the "right ear E2" are included.

[0010] As shown in FIG. 1, the ear device 100 according to the embodiment includes a left ear part 100a and a right ear part 100b. When the left ear part 100a and the right ear part 100b are not specifically distinguished from each other, they are simply referred to as the ear device 100. As shown in FIGS. 2 and 8, the ear device 100 according to the embodiment includes a main body 1 and a pad member 2 for each of the left ear part 100a and the right ear part 100b. The pad member 2 is an earpiece that is inserted into the user's ear canal entrance Ea (ear canal; see FIGS. 6 and 10) during use, and the ear device 100 according to the embodiment is a so-called canal-type (sealed) ear device. Furthermore, the left ear part 100a and the right ear part 100b of the ear device 100 are designed to be used wirelessly. The ear device 100 of this embodiment may be an earphone that can hear the output sound (sound waves) when worn in the user's ear, a hearing aid, or a detector that detects various biological information such as body temperature, and may broadly include devices worn in the ear.

[0011] 2 and 8, the main body 1 has a housing 10 and a shaft 11 that protrudes from one side of the housing 10. The housing 10 and the shaft 11 of the main body 1 are made of, for example, various resins. Note that the material from which the main body 1 is made is not limited to resin, and may be, for example, various metals.

[0012] Various functional units 15 are housed inside the housing 10. For example, if the ear device 100 is an earphone, the functional unit 15 includes a driver unit that converts electrical signals supplied from an external device into sound and generates it. Furthermore, if the ear device 100 is a biological information detector such as an ear-mounted thermometer, a sensor (not shown) appropriate for the application is provided on the stem 11 or the like. One type of sensor may be used, or multiple types may be installed to detect various types of biological information. In this case, the functional unit 15 includes a control device that receives detected information from the sensor and stores and analyzes it as appropriate. The ear device 100 may also have multiple functions, such as both an earphone and a biological information detector. Furthermore, if the ear device 100 is a hearing aid, for example, the functional unit 15 is provided to enable the ear device 100 to function as a hearing aid. In this case, the functional unit 15 may be, for example, a microphone serving as a sound wave input unit (sound collection unit) that collects sound waves (sound data) from the outside, or a control device that analyzes the sound waves (sound data) collected by the microphone.

[0013] 2 and 8, the pad member 2 is attached to a shaft portion 11 provided on one side of the housing 10, and is placed at a position corresponding to the entrance of the ear canal when the ear device 100 is worn. The pad member 2 is preferably made of a soft resin that has a high degree of freedom of deformation and fits comfortably in the user's ear, such as silicone. The material for forming the pad member 2 is not limited to silicone, but may be, for example, urethane resin, various foam resins, or the like.

[0014] Furthermore, the ear device 100 in the embodiment has a magnet 5 provided on the housing 10. That is, a left-use magnet 51 is provided on the housing 10 of the left ear part 100a, and a right-use magnet 52 is provided on the housing 10 of the right ear part 100b. Note that, hereinafter, when simply referring to a "magnet 5," there is no particular distinction between left and right, and the term "magnet 5" is used to include both the left-use magnet 51 and the right-use magnet 52. The method for attaching the magnet 5 and the size, shape, etc. of the magnet 5 are not particularly limited, but the first embodiment shows an example in which a cylindrical magnet 5 is attached to the outer periphery of the housing 10 of the main body 1, and the second embodiment shows an example in which a ring-shaped magnet 5 is attached to the outer periphery of the housing 10 of the main body 1. Note that in both the first and second embodiments, the magnet 5 may be cylindrical or ring-shaped.

[0015] The left magnet 51 provided in the left ear part 100a has a second polarity that attracts the first magnet 61 having the first polarity, and the right magnet 52 provided in the right ear part 100b has a first polarity that attracts the second magnet 62 having the second polarity. That is, in this embodiment, a first magnet 61 having a first polarity (e.g., N pole) is disposed around the left ear E1 or on the back side of the ear corresponding to the ear canal entrance Ea of the left ear E1, and the left-use magnet 51 provided in the left ear part 100a has a second polarity (e.g., S pole) that attracts the first magnet 61. For example, when the housing 10 of the left ear part 100a with the left-use magnet 51 attached is viewed in cross section, the left-use magnet 51 has an N pole on the inner side that contacts the housing 10 and an S pole on the outer side (the outer peripheral side that contacts the ear), as shown in FIG. 3. The first magnet 61 is attached so that the surface having the first polarity (e.g., N pole) faces the side that faces the ear device 100 when the ear device 100 is attached to the ear E (the side that contacts the back of the ear, the side closer to the ear canal entrance Ea), as shown in FIGS. 5A and 6, for example. Therefore, when the left ear part 100a is attached to the left ear E1, the left magnet 51 of the left ear part 100a, which has the second polarity (for example, S pole), and the first magnet 61, which has the first polarity (for example, N pole), face each other across the ear E from the front and back, and are attracted to each other. This allows the left ear part 100a to be fixed to the left ear E1.

[0016] Furthermore, a second magnet 62 having a second polarity (e.g., S pole) is disposed around the right ear E2 or on the back side of the ear corresponding to the ear canal entrance Ea of the right ear E2, and the right magnet 52 provided in the right ear part 100b has a first polarity (e.g., N pole) that attracts the second magnet 62. That is, although not shown, when the right magnet 52 is cross-sectionally viewed, the inner part that contacts the housing 10 is the S pole, and the outer side (the outer peripheral side that contacts the ear) is the N pole, which is the opposite of the case shown in FIG. 3. The second magnet 62 is attached so that the surface having the second polarity (e.g., S pole) faces the side that faces the ear device 100 when the ear device 100 is worn on the ear E (the side that contacts the back of the ear, the side that is closer to the ear canal entrance Ea), as shown in FIG. 5B, for example. Therefore, when the right ear part 100b is attached to the right ear E2, the right magnet 52 of the right ear part 100b, which has a first polarity (e.g., north pole), and the second magnet 62, which has a second polarity (e.g., south pole), face each other across the ear E from the front and back, and are attracted to each other. This allows the right ear part 100b to be fixed to the right ear E2. In this embodiment, a system is configured including the ear device 100, the first magnet 61, and the second magnet 62.

[0017] [First embodiment] In this embodiment, as shown in FIG. 1, when the eyeglasses 60 are worn, a first magnet 61 having a first polarity (e.g., north pole) on the surface that contacts the back of the ear is placed around (behind) the left ear E1, and a second magnet 62 having a second polarity (e.g., south pole) on the surface that contacts the back of the ear is placed around (behind) the right ear E2. As shown in FIG. 4, the eyeglasses 60 include a lens frame 65 to which lenses 64 are fixed, and a temple frame 66 connected to the lens frame 65. The temple frame 66 includes a frame portion 67 and an ear hook portion 68 that is placed on the ear. The first magnet 61 and the second magnet 62 are provided on the left and right temple frames 66 of the eyeglasses 60, for example, on the ear hook portion 68 in the illustrated example.

[0018] In this embodiment, the first magnet 61 is provided on the ear hook portion 68 of the left temple frame 66, and the second magnet 62 is provided on the ear hook portion 68 of the right temple frame 66. The method for attaching the first magnet 61 and the second magnet 62 to the temple frame 66 is not particularly limited. The first magnet 61 and the second magnet 62 may be, for example, attached to the outside of the ear hook portion 68 or embedded inside the ear hook portion 68. When the ear hook portion 68 of the eyeglasses 60 is placed on the ear, the surface of the first magnet 61 having the first polarity (e.g., N pole) faces behind the ear and comes into contact with the back of the ear (see FIGS. 5A and 6). Furthermore, the surface of the second magnet 62 having the second polarity (e.g., S pole) faces behind the ear and comes into contact with the back of the ear (see FIG. 5B). For this reason, when the user wears the eyeglasses 60, the first magnet 61 is placed behind the left ear E1 with the surface having the first polarity (e.g., north pole) in contact with the back of the ear, and the second magnet 62 is placed behind the right ear E2 with the surface having the second polarity (e.g., south pole) in contact with the back of the ear. The surface of the left magnet 51 provided in the left ear part 100a has a second polarity (e.g., south pole) on the front side (outside) that attracts the first magnet 61 (e.g., north pole), and the right magnet 52 provided in the right ear part 100b has a first polarity (e.g., north pole) on the front side (outside) that attracts the second magnet 62 (e.g., south pole).

[0019] As a result, if a user wearing glasses 60 mistakenly attempts to wear the right ear part 100b on the left ear E1 or the left ear part 100a on the right ear E2, the ear device 100 cannot be worn on the ear E due to the mutual repulsive forces between the first magnet 61 and the right magnet 52 of the right ear part 100b, and between the second magnet 62 and the left magnet 51 of the left ear part 100a. On the other hand, when correctly wearing the left ear part 100a on the left ear E1, the first magnet 61 and the left magnet 51 of the left ear part 100a sandwich the left ear E1 from the front and back, and an attractive force acts between the first magnet 61 and the left magnet 51 of the left ear part 100a, so that the left ear part 100a is fastened to the left ear E1. Furthermore, when wearing the right ear part 100b on the right ear E2, the right ear E2 is sandwiched between the second magnet 62 and the right magnet 52 of the right ear part 100b from the front and back, and an attractive force acts between the second magnet 62 and the right magnet 52 of the right ear part 100b, causing the right ear part 100b to lock onto the right ear E2.

[0020] As described above, in this embodiment, the ear device 100 includes a left ear part 100a and a right ear part 100b, and the left ear part 100a has a left magnet 51 having a second polarity (e.g., an S pole) on its outer periphery that attracts a first magnet 61 having a first polarity (e.g., an N pole) on the periphery (behind the ear) of the left ear E1, and the right ear part 100b has a right magnet 52 having a first polarity (e.g., an N pole) on its outer periphery that attracts a second magnet 62 having a second polarity (e.g., an S pole) on the periphery (behind the ear) of the right ear E2.

[0021] As a result, when the left ear part 100a is worn on the left ear E1 and the right ear part 100b is worn on the right ear E2, the ear device 100 can be worn smoothly simply by bringing the ear device 100 close to the ear E due to the attractive force between the magnets (i.e., the first magnet 61 and the left magnet 51, and the second magnet 62 and the right magnet 52). Furthermore, when the left and right ear devices 100 are worn correctly, the magnets (i.e., the first magnet 61 and the left magnet 51, and the second magnet 62 and the right magnet 52) ​​are joined by magnetic force, so that the ear device 100 is unlikely to come off even when playing sports or the like while worn on the ear E, and it is possible to prevent the ear device 100 from falling off and being lost unintentionally.

[0022] Furthermore, the left magnet 51 provided on the left ear part 100a and the right magnet 52 provided on the right ear part 100b have different polarities, and the left magnet 51 repels the second magnet 62 provided on the right ear hook 68 of the eyeglasses 60, while the right magnet 52 repels the first magnet 61 provided on the left ear hook 68 of the eyeglasses 60. Many ear devices 100 have almost the same shape and color on both sides, making it difficult to distinguish between left and right based on appearance alone. In this regard, the ear device 100 according to the embodiment cannot be worn if the user mistakenly wears the ear device 100 on the left or right side. This ensures that the ear device 100 is always worn correctly.

[0023] In this embodiment, the left ear part 100a and the right ear part 100b each include a housing 10 and a pad member 2 that is attached to one side of the housing 10 and inserted into the ear canal entrance (ear hole) Ea when worn, and the left magnet 51 and the right magnet 52 are provided on the housing 10. As such, the ear device 100 according to this embodiment is a canal-type ear device that includes the pad member 2, so it is relatively difficult to fall off and there is little risk of sound leaking to the surroundings.

[0024] Furthermore, in this embodiment, the first magnet 61 and the second magnet 62 are provided on the temple frames 66 of the eyeglasses 60, and the left ear part 100a is fastened to the left ear E1 by sandwiching the left ear E1 from the front and back between the first magnet 61 and the left magnet 51, and the right ear part 100b is fastened to the right ear E2 by sandwiching the right ear E2 from the front and back between the second magnet 62 and the right magnet 52. In this way, because the first magnet 61 and the second magnet 62 for fastening the ear device 100 are provided on the temple frames 66 of the eyeglasses 60, a user who normally wears eyeglasses can fasten the ear device 100 without any special wearing equipment.

[0025] Furthermore, in this embodiment, the left ear part 100a and the right ear part 100b are used wirelessly. This eliminates the hassle of tangled wires and allows the ear device 100 to be used without getting in the way, even when playing sports. Furthermore, because the ear device 100 is connected to the ear E by the magnetic force of the magnets (i.e., the first magnet 61 and the left magnet 51, and the second magnet 62 and the right magnet 52), there is little risk of it falling or getting lost, even though it is not connected together by a wire.

[0026] [Second embodiment] In this embodiment, as shown in FIG. 7 , the first magnet 71 and the second magnet 72 are provided on the back side of the ear E, near the ear canal entrance (ear hole) Ea. The method for providing the first magnet 71 and the second magnet 72 is not particularly limited. For example, the first magnet 71 and the second magnet 72 are attached to a tape-like substrate (not shown) with an adhesive surface and then attached to the back side of the ear E, near the ear canal entrance Ea. The substrate may be, for example, a cloth, a nonwoven urethane fabric, a polyethylene sheet, or the like. Note that the substrate may be any material that provides little discomfort and resistance when attached to the ear E, and is not limited to the materials listed here. Furthermore, the shape, size, thickness, etc., of the substrate are not particularly limited. The method for providing the first magnet 71 and the second magnet 72 on the ear E is not limited to attaching them to a substrate. The first magnet 71 and the second magnet 72 may be attached in a manner that places minimal strain on the ear E and is difficult to remove. For example, the first magnet 71 and the second magnet 72 may be attached to a clip-shaped member, and the clip-shaped member may be used to clamp the ear and secure it to the back of the ear.

[0027] 9A and 9B, the first magnet 71 and the second magnet 72 are enlarged to show their polarities. As shown in FIGS. 9A and 10, the first magnet 71 is attached to the back of the ear with a surface having a first polarity (e.g., N pole) facing the ear device 100 (the side closer to the ear canal entrance Ea) when the ear device 100 is attached to the ear E. As shown in FIG. 9B, the second magnet 72 is attached to the back of the ear with a surface having a second polarity (e.g., S pole) facing the ear device 100 when the ear device 100 is attached to the ear E. The left magnet 51 is configured so that the side facing the first magnet 71 (i.e., the outer circumferential side that contacts the ear) has the second polarity (e.g., S pole) when the ear device 100 (left ear part 100a) is attached to the ear E. In addition, when the ear device 100 (right ear part 100b) is worn on the ear E, the right magnet 52 is configured so that the side facing the second magnet 72 (i.e., the outer peripheral side that comes into contact with the ear) has a first polarity (e.g., a north pole).

[0028] The "near the entrance Ea of the ear canal of the ear E" where the first magnet 71 and the second magnet 72 are attached refers to the concha (cavity of the concha or vestibulo-concha) Eb or its vicinity, or the earlobe Ec, as shown in Fig. 10, and the first magnet 71 and the second magnet 72 are placed on the back of the corresponding ear. The first magnet 71 and the second magnet 72 only need to be placed in positions where they can magnetically interact with the left magnet 51 and the right magnet 52 provided in the ear device 100, and the specific positions are not limited to those shown in the example.

[0029] In this embodiment, the left ear part 100a is held near the entrance Ea of the ear canal of the left ear E1 by magnetic coupling between a first magnet 71 having a first polarity (e.g., north pole) attached to the back of the ear corresponding to the concha Eb of the left ear E1 and a left magnet 51 having a second polarity (e.g., south pole). The right ear part 100b is held near the entrance Ea of the ear canal of the right ear E2 by magnetic coupling between a second magnet 72 having a second polarity (e.g., south pole) attached to the back of the ear corresponding to the concha Eb of the right ear E2 and a right magnet 52 having a first polarity (e.g., north pole).

[0030] For this reason, if a user mistakenly attempts to wear the right ear part 100b on the left ear E1 or the left ear part 100a on the right ear E2 with the first magnet 71 and the second magnet 72 attached (adhered) to the backside of each ear E, the ear device 100 cannot be worn due to the repulsive forces that repel each other between the first magnet 71 and the right magnet 52, and between the second magnet 72 and the left magnet 51. On the other hand, when correctly wearing the left ear part 100a on the left ear E1, by sandwiching the left ear E1 from the front and back between the first magnet 71 attached to the backside of the left ear E1 and the left magnet 51 of the left ear part 100a, a mutual attractive force acts between the first magnet 71 and the left magnet 51 of the left ear part 100a, and the left ear part 100a is locked to the left ear E1. Furthermore, when wearing the right ear part 100b on the right ear E2, the right ear E2 is sandwiched between the second magnet 72 attached to the right ear E2 and the right magnet 52 of the right ear part 100b, and an attractive force acts between the second magnet 72 and the right magnet 52 of the right ear part 100b, thereby locking the right ear part 100b into the right ear E2.

[0031] As described above, in addition to the effects described in the first embodiment, the present embodiment has the following effects. Specifically, in the present embodiment, the first magnet 71 and the second magnet 72 are provided on the back of the ear near the ear canal entrance Ea of the ear E (e.g., the concha Eb). The left ear part 100a is secured near the ear canal entrance Ea of the left ear E1 by the attractive force between the first magnet 71 and the left magnet 51, and the right ear part 100b is secured near the ear canal entrance Ea of the right ear E2 by the attractive force between the second magnet 72 and the right magnet 52. In the present embodiment, by attaching (adhering) the first magnet 71 and the second magnet 72 to the back of the ear E, the ear device 100 can be attached to the correct ear E without the need for any additional fasteners. This prevents the ear device 100 from being attached incorrectly to the left or right ear. Furthermore, when the ear device 100 is worn correctly on both the left and right sides, it is firmly locked in place by the attractive forces between the first magnet 71 and the left-side magnet 51 and between the second magnet 72 and the right-side magnet 52, and is unlikely to come off even when playing sports, etc. This also prevents the ear device 100 from falling off unintentionally.

[0032] In addition, in this embodiment, the first magnet 71 and the second magnet 72 are simply attached (adhered) to the ear E. Therefore, even a user who does not normally wear eyeglasses or the like can fasten the ear device 100 with the first magnet 71 and the second magnet 72.

[0033] Although the embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to the above-described embodiments, and various modifications are possible without departing from the spirit of the present invention. For example, in the above embodiment, the ear device 100 is a canal type that includes a pad member 2 and is attached to the ear E by inserting the pad member 2 through the ear canal entrance Ea. However, the ear device 100 is not limited to a canal type. For example, the ear device 100 may be an inner-ear type (open type). In this case, the pad member 2 is placed in a position corresponding to the ear canal entrance when worn. When the ear device 100 is an open type, the pad member 2 may be placed near the ear canal entrance, such as the concha. In this case, a left-use magnet 51 and a right-use magnet 52 are provided in the left ear part 100a and the right ear part 100b, respectively, in portions corresponding to the main body 1.

[0034] Furthermore, the ear device 100 is not limited to being wireless. The left ear part 100a and the right ear part 100b may be integrally connected by a wire, or may be used while connected to audio equipment or the like by a wire. If a wire is provided, the ear device 100 will not fall to the ground even if the user incorrectly tries to wear the ear device 100 upside down and it is repelled by the first magnet 61 or the second magnet 62 located around the ear E or near the entrance Ea of the ear canal of the left ear. This makes it difficult to lose the ear device 100.

[0035] Although several embodiments of the present invention have been described above, the scope of the present invention is not limited to the above-described embodiments, and the specific configurations, structures, positional relationships, etc. shown in the above-described embodiments can be modified as appropriate without departing from the spirit of the present invention. Furthermore, the present invention includes the scope of the invention described in the claims and their equivalents. [Explanation of symbols]
