[0009] An electronic device according to one aspect of the present disclosure is an electronic device installed inside a mobile body, and includes a first housing that houses a converter that converts an audio signal from a digital signal to an analog signal, and a second housing that is separate from the first housing and is provided with a jack that outputs the audio signal converted to the analog signal, and the first housing and the second housing are connected via a first cable.

[0010] With this, the second housing in which the jack that outputs the audio signal is provided is separate from the first housing that houses the converter, so the second housing can be prevented from becoming larger than when the converter is housed in the second housing.

[0011] Furthermore, in an electronic device according to one aspect of the present disclosure, the first housing may be installed in a first position that cannot be directly touched by a user of the electronic device, and the jack may be installed in a second position that can be directly touched by the user.

[0012] This makes it possible to prevent the jack located in a position where it can be directly touched by the user from becoming too large.

[0013] Furthermore, in an electronic device according to one aspect of the present disclosure, the first position may include the inside of a first seat on which the user sits, the inside of a second seat located near the first seat, or the inside of a structure installed around the first seat, and the second position may include a position on the first seat that is exposed to the outside, a position on the second seat that is exposed to the outside, or a position on the structure that is exposed to the outside.

[0014] This prevents the jack exposed near the user's seat from becoming too large.

[0015] In addition, in an electronic device according to one aspect of the present disclosure, the electronic device may further include a third housing that houses a processor that expands the compressed audio signal and is separate from the first housing and the second housing, and the first housing and the third housing may be connected via a second cable.

[0016] According to this, since the third housing that houses the processor is separate from the first housing and the second housing, the first housing or the second housing can be prevented from becoming larger than when the processor is housed in the first housing or the second housing.

[0017] In addition, in the electronic device according to one aspect of the present disclosure, the number of cores in the second cable may be smaller than the number of cores in the first cable.

[0018] This makes it easier to reduce the weight of the entire electronic device.

[0019] In addition, in an electronic device according to one aspect of the present disclosure, the first housing is provided with a first connector to which the first cable is connected and a second connector to which the second cable is connected, and the first connector and the second connector may have different shapes.

[0020] This makes it easier to use suitable cables for the first cable and the second cable.

[0021] In addition, in an electronic device according to one aspect of the present disclosure, the first connector and the second connector may be arranged back to back, and the first housing may be formed so that the connection direction of the first cable to the first connector is the longitudinal direction.

[0022] This can prevent the first housing from increasing in size in a direction perpendicular to the direction in which the first cable is connected to the first connector.

[0023] In addition, in an electronic device according to one aspect of the present disclosure, the first housing may obtain necessity information regarding the need for power supply to the jack via the second cable, determine the need based on the necessity information, and supply the power via the first cable if it determines that the power supply is required.

[0024] This allows power to be supplied to the jack when it is required.

[0025] In addition, in the electronic device according to one aspect of the present disclosure, the second housing may have a plurality of models with different jack shapes.

[0026] This allows audio signals to be output to a plurality of devices having plugs with different shapes.

[0027] In addition, in the electronic device according to one aspect of the present disclosure, the jack may include a jack that complies with the ARINC standard.

[0028] This allows audio signals to be output to devices that have plugs that comply with the ARINC standard.

[0029] Hereinafter, the embodiments will be specifically described with reference to the drawings.

[0030] The embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component placement and connection configurations, steps, and step order shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Furthermore, among the components in the following embodiments, components that are not recited in independent claims are described as optional components. Furthermore, each drawing is a schematic diagram and is not necessarily an exact illustration. Furthermore, the same components are designated by the same reference numerals in each drawing.

[0031] (Embodiment) FIG. 1 is a schematic diagram showing an electronic device 10 according to an embodiment. FIG. 2 is a schematic diagram showing a first housing 20 of the electronic device 10 of FIG. 1. (a) of FIG. 2 shows the first housing 20 as viewed from one direction, and (b) of FIG. 2 shows the first housing 20 as viewed from a direction perpendicular to the one direction. FIG. 3 is a schematic diagram showing a second housing 30a of the electronic device 10 of FIG. 1. The configuration of the electronic device 10 will be described with reference to FIGS. 1 to 3.

[0032] The electronic device 10 is an electronic device provided inside a moving object, and converts an audio signal from a digital signal to an analog signal and outputs the converted signal. For example, the moving object is a vehicle capable of carrying people, such as a car, an airplane, or a ship. The vehicle is an automobile, a railroad car, or the like. As shown in FIG. 1, in this embodiment, the electronic device 10 is installed in a seat 90 installed inside the moving object.

[0033] The seat 90 is a seat on which a user of the electronic device 10 sits. The user of the electronic device 10 is a passenger or other occupant of a moving object. Hereinafter, the user of the electronic device 10 may be simply referred to as a user. The seat 90 has a seat portion 91 on which the user sits, legs 92 that support the seat portion 91, a backrest portion 93 that supports the user sitting on the seat portion 91 from behind, and armrest portions (armrests) 94 on which the user sitting on the seat portion 91 can place their elbows or the like. The user can use the electronic device 10 while sitting on the seat portion 91.

[0034] The electronic device 10 includes a first housing 20, a second housing 30a, a third housing 40, a first cable 50, and a second cable 60.

[0035] The first housing 20 houses the converter 21, the supply unit 26, and the amplifier 27. The first housing 20 is installed at a first position where the user cannot directly touch it. Therefore, a user who is a passenger on a vehicle cannot directly touch the first housing 20 when using the electronic device 10 for operations typically expected of a passenger, such as playing music. In the present embodiment, the first position is inside the seat 90. Specifically, the first position is inside the seat 91. When the user uses the electronic device 10 while sitting on the seat 91, the first housing 20 is installed inside the seat 91, and therefore the user cannot directly touch the first housing 20. Note that the inside of the seat 90 is not limited to the inside of the seat 91 but also includes the inside of a housing installed below the seat 91. The first position may also be inside the armrest 94, etc.

[0036] As shown in FIG. 2, the first housing 20 is provided with a first connector 22 and a second connector 23. The first housing 20 is formed so that the direction in which the first cable 50 is connected to the first connector 22 (see arrow A in FIG. 2) is the longitudinal direction. The first housing 20 is also formed so that the direction perpendicular to the longitudinal direction is the lateral direction (see arrow B in FIG. 2(a)), and the direction perpendicular to both the longitudinal direction and the lateral direction is the thickness direction (see arrow C in FIG. 2(b)). The longitudinal dimension of the first housing 20 is greater than the lateral dimension and thickness dimension of the first housing 20. Hereinafter, the connection direction of the first cable 50 to the first connector 22 may be simply referred to as the connection direction.

[0037] The first connector 22 is a connector to which the first cable 50 is connected. The first connector 22 is a female connector into which the connector 51 of the first cable 50, which is a male connector, is inserted in the connection direction. The first connector 22 is provided on an end surface 24 on one side in the longitudinal direction of the first housing 20.

[0038] The second connector 23 is a connector to which the second cable 60 is connected. The second connector 23 is arranged back to back with the first connector 22. The second connector 23 is a female connector into which the connector 61 of the second cable 60, which is a male connector, is inserted in the opposite direction to the connection direction. The second connector 23 is provided on an end surface 25 on the other side in the longitudinal direction of the first housing 20.

[0039] The first connector (terminal) 22 and the second connector (terminal) 23 have different shapes. For example, the first connector 22 has a shape that conforms to a certain standard, and the second connector 23 has a shape that conforms to a standard different from the certain standard. In this way, the standard to which the first connector 22 conforms is different from the standard to which the second connector 23 conforms, and therefore the shapes of the first connector 22 and the second connector 23 are different. Note that these shapes are not particularly limited, and they may be any shapes that conform to the standard to be used.

[0040] As shown in FIGS. 1 and 3, the second housing 30a is provided with a jack 31a. Note that there may be multiple models of the second housing. For example, in addition to the second housing 30a, there may be a second housing 30b as shown in FIG. 4, a second housing 30c as shown in FIG. 5, and a second housing 30d as shown in FIG. 6. While the second housing 30a is connected to the first cable 50 in FIGS. 1 and 3, instead of the second housing 30a, the second housing 30b may be connected to the first cable 50 as shown in FIG. 4, the second housing 30c may be connected to the first cable 50 as shown in FIG. 5, or the second housing 30d may be connected to the first cable 50 as shown in FIG. 6.

[0041] As shown in FIG. 4, the second housing 30b is provided with a jack 31b. As shown in FIG. 5, the second housing 30c is provided with a jack 31c. As shown in FIG. 6, the second housing 30d is provided with a jack 31d. Each of the jacks 31a, 31b, 31c, and 31d is an audio jack that outputs an audio signal converted into an analog signal. When an audio signal is received via the first cable 50 with a plug inserted into the jack, each of the jacks 31a, 31b, 31c, and 31d outputs the audio signal to a device having the plug. This allows the device to output audio corresponding to the audio signal, allowing the user to listen to the audio corresponding to the audio signal using the device. For example, the device may be earphones or headphones.

[0042] The multiple jacks 31a, 31b, 31c, and 31d are of different types (models) and have different shapes. For example, a jack that matches the shape of the plug of a device (such as earphones) to be used can be selected from the multiple jacks 31a, 31b, 31c, and 31d, and the second housing associated with the selected jack can be connected to the first cable 50 for use. The multiple jacks 31a, 31b, 31c, and 31d include jacks that comply with the ARINC standard. Here, the jacks 31b, 31c, and 31d comply with the ARINC standard.

[0043] For example, jack 31b is an audio jack that complies with the ARINC628 standard. ARINC628 is a standard for interfaces of cabin equipment in aircraft. The ARINC628 standard specifies multiple types of audio jacks, including not only two-port jacks like 31a, but also two-port jacks with different shapes like 31c, one-port jacks like 31b, and three-port jacks like 31d. That is, there are multiple models of the second housing with different jack shapes like these. Because second housings 30a, 30b, 30c, and 30d are configured to be detachable from first cable 50 or first housing 20, the model can be changed depending on the shape of the plug of a device (such as an earphone) that a user is expected to use in seat 90.

[0044] Furthermore, some types of audio jacks conforming to the ARINC628 standard require a power supply to the device to be connected, so a supply unit 26, which will be described later, determines whether a power supply is required, and for audio jacks that require a power supply, power is supplied in addition to an audio signal from first housing 20. For example, an audio jack may require a power supply to drive the noise canceling function of earphones connected to the audio jack.

[0045] The audio jacks mounted on the second housing 30a etc. are not limited to those conforming to the ARINC standard, but may be general audio jacks. Also, the second housing 30a etc. may be equipped with multiple audio jacks in one housing, or may be equipped with a USB (UNIVERSAL SERIAL BUS) or the like.

[0046] Each of the jacks 31a, 31b, 31c, and 31d is installed at a second position where the user can directly touch them. Therefore, when using the electronic device 10, the user can directly touch each of the jacks 31a, 31b, 31c, and 31d. In the present embodiment, the second position is a position on the seat 90 where the jacks are exposed to the outside. Specifically, the second position is a position on the armrest 94 where the jacks are exposed to the outside. When the user uses the electronic device 10 while sitting on the seat 91, the user can directly touch each of the jacks 31a, 31b, 31c, and 31d because each of the jacks 31a, 31b, 31c, and 31d is installed at the armrest 94 and exposed to the outside. Note that the second position may also be a position on the seat 91, the leg 92, or the backrest 93 where the jacks are exposed to the outside. Each of second housings 30a, 30b, 30c, and 30d is installed inside armrest 94 so that the user cannot directly touch it. In this way, each of second housings 30a, 30b, 30c, and 30d is installed so that the jacks provided in the second housing are exposed to the outside, but the second housing itself is not exposed to the outside.

[0047] As described above, in this embodiment, since there are a plurality of models of second housings 30a, 30b, 30c, and 30d, it is possible to change the second housing connected to first cable 50 depending on the shape of the jack, etc. Note that since second housings 30a, 30b, 30c, and 30d are separate from first housing 20, it is possible to change the second housing without changing first housing 20, and first housing 20 can be made common to second housings 30a, 30b, 30c, and 30d.

[0048] As shown in FIG. 1 , the third housing 40 houses a processor 41. The third housing 40 is installed at a third position that the user cannot directly touch. Therefore, the user cannot directly touch the third housing 40 when using the electronic device 10. In the present embodiment, the third position is inside the seat 90. Specifically, the third position is inside the seat portion 91. When the user uses the electronic device 10 while sitting on the seat portion 91, the user cannot directly touch the third housing 40 because the third housing 40 is installed inside the seat portion 91. The third position may be inside the armrest portion 94, for example.

[0049] The first cable 50 is connected to the first housing 20 and the second housing 30a, and the first housing 20 and the second housing 30a are connected via the first cable 50. As described above, one end of the first cable 50 is provided with a connector 51, which is connected to the first connector 22. The other end of the first cable 50 is provided with a connector 52 (see FIG. 7) having the same shape as the connector 51, and the second housing 30 is provided with a connector 32a (see FIG. 7) having the same shape as the first connector 22, which is connected to the connector 32a. Note that, for example, the other end of the first cable 50 may be fixed to the second housing 30a. In this case, a male connector and a female connector may be provided between one end and the other end of the first cable 50, so that the first cable 50 can be connected or disconnected using the male connector and the female connector.

[0050] The second cable 60 is connected to the first housing 20 and the third housing 40, and the first housing 20 and the third housing 40 are connected via the second cable 60. As described above, the second cable 60 has a connector 61 at one end, which is connected to the second connector 23. The second cable 60 has a connector 62 (see FIG. 7) having the same shape as the connector 61 at the other end, and the third housing 40 has a connector 42 (see FIG. 7) having the same shape as the second connector 23, which is connected to the connector 42. Note that, for example, the other end of the second cable 60 may be fixed to the third housing 40. In this case, a male connector and a female connector may be provided between the one end and the other end of the second cable 60, so that the second cable 60 can be connected or disconnected using the male connector and the female connector. The number of cores in the second cable 60 is smaller than the number of cores in the first cable 50. The number of cores refers to the number of core wires. By providing a second cable 60 having fewer cores than the first cable 50 in this manner, the weight of the cable connecting the third housing 40 and the first housing 20 can be reduced, making it easier to reduce the weight of the entire electronic device 10.

[0051] Fig. 4 is a block diagram showing the functional configuration of the electronic device 10 of Fig. 1. The functional configuration of the electronic device 10 will be described with reference to Fig. 4.

[0052] As shown in FIG. 4, the electronic device 10 includes a converter 21, a supply unit 26, an amplifier 27, a jack 31a (31b, 31c, 31d), a processor 41, and the like.

[0053] The converter 21 converts the audio signal from a digital signal to an analog signal, for example, a D / A converter.

[0054] The supply unit 26 acquires necessity information regarding the necessity of power supply to the jack 31a (31b, 31c, 31d) via the second cable 60, determines the necessity based on the necessity information, and supplies power via the first cable 50 if it determines that power supply is required. The necessity information indicates whether power supply is required to the jack 31a (31b, 31c, 31d). The necessity information indicates whether power supply is required to the jack provided in the second housing connected to the first cable 50. If the necessity information indicates that power supply is required, the supply unit 26 determines that power supply is required. If the necessity information indicates that power supply is not required, the supply unit 26 determines that power supply is not required. For example, whether power supply is required is set in advance by an administrator or the like of the audio system in the mobile object, and necessity information indicating the setting by the administrator or the like is transmitted to the electronic device 10 from an external device or the like. The power supplied by the supply unit 26 is obtained from a battery or the like installed in the mobile object. For example, the supply unit 26 is realized by a processor or the like.

[0055] The processor 41 decompresses the compressed audio signal and transmits the decompressed audio signal to the transducer 21 via a second cable 60 .

[0056] A connector 43 is provided in the third housing 40. A connector 71 of a cable 70 is connected to the connector 43. An external device or the like is connected to the opposite end of the cable 70 from the connector 71.

[0057] For example, when a user wishes to listen to music stored in a content server or the like installed in a mobile object, a compressed audio signal relating to the music is transmitted from an external device or the like to the processor 41 via the cable 70. The processor 41 decompresses the received audio signal and transmits the decompressed audio signal to the converter 21 via the second cable 60. The converter 21 converts the received audio signal from a digital signal to an analog signal and transmits the converted analog audio signal to the jack 31a (31b, 31c, 31d) via the first cable 50. Here, the audio signal is amplified by the amplifier 27 before being transmitted. By inserting a plug into the jack 31a (31b, 31c, 31d), the user can listen to music using the device (e.g., earphones) that has the plug, which outputs the music.

[0058] Furthermore, the necessity information is transmitted from an external device or the like to processor 41 via cable 70. Processor 41 transmits the received necessity information to supply unit 26 via second cable 60. Supply unit 26 determines whether power supply to jack 31a (31b, 31c, 31d) is necessary based on the necessity information, and if it determines that power supply is necessary, supplies power to jack 31a (31b, 31c, 31d) via first cable 50.

[0059] As described above, in the electronic device 10, the first housing 20, the second housing 30a (30b, 30c, 30d), and the third housing 40 are separate bodies. Therefore, the first housing 20, the second housing 30a (30b, 30c, 30d), and the third housing 40 can be made smaller than when the jack 31a (31b, 31c, 31d), the converter 21, the processor 41, etc. are housed in a single housing. Although the space available for installing these components is limited inside a mobile object, miniaturizing these components makes it easier to install them in a limited space.

[0060] Furthermore, by arranging the first housing 20 close to the second housing 30a (30b, 30c, 30d), the first cable 50 can be shortened. By arranging the first housing 20 close to the third housing 40, the second cable 60 can be shortened.

[0061] Furthermore, if the converter 21 breaks down, the first housing 20 can be removed and repaired, and there is no need to remove the second housing 30a (30b, 30c, 30d) and the third housing 40, improving maintainability. Similarly, if the jack 31a (31b, 31c, 31d) breaks down, the second housing 30a (30b, 30c, 30d) can be removed and repaired, and there is no need to remove the first housing 20 and the third housing 40. Furthermore, if the processor 41 breaks down, the third housing 40 can be removed and repaired, and there is no need to remove the first housing 20 and the second housing 30a (30b, 30c, 30d). In this way, maintainability can be improved.

[0062] The electronic device 10 of this embodiment is an electronic device installed inside a mobile body, and includes a first housing 20 that houses a converter 21 that converts an audio signal from a digital signal to an analog signal, and a second housing 30a (30b, 30c, 30d) that is separate from the first housing 20 and is provided with a jack 31a (31b, 31c, 31d) that outputs the audio signal converted to an analog signal, and the first housing 20 and the second housing 30a (30b, 30c, 30d) are connected via a first cable 50.

[0063] According to this, the second housing 30a (30b, 30c, 30d) in which the jack 31a (31b, 31c, 31d) that outputs the audio signal is provided is separate from the first housing 20 that houses the converter 21, so the second housing 30a (30b, 30c, 30d) can be prevented from becoming larger than when the converter 21 is housed in the second housing 30a (30b, 30c, 30d).

[0064] Furthermore, in the electronic device 10 according to this embodiment, the first housing 20 is installed in a first position where the user of the electronic device 10 cannot directly touch it, and the jack 31a (31b, 31c, 31d) is installed in a second position where the user can directly touch it.

[0065] This makes it possible to prevent the jack 31a (31b, 31c, 31d) located in a position where it can be directly touched by the user from becoming too large.

[0066] In addition, in electronic device 10 according to the present embodiment, the first position is inside seat 90 where the user sits, and the second position is a position on seat 90 that is exposed to the outside.

[0067] This makes it possible to prevent the jack 31a (31b, 31c, 31d) exposed around the seat 90 of the user from becoming too large.

[0068] In addition, the electronic device 10 according to this embodiment further includes a third housing 40 that houses a processor 41 that expands compressed audio signals and is separate from the first housing 20 and the second housing 30a (30b, 30c, 30d), and the first housing 20 and the third housing 40 are connected via a second cable 60.

[0069] According to this, since the third housing 40 that houses the processor 41 is separate from the first housing 20 and the second housing 30a (30b, 30c, 30d), the size of the first housing 20 or the second housing 30a (30b, 30c, 30d) can be prevented from increasing compared to when the processor 41 is housed in the first housing 20 or the second housing 30a (30b, 30c, 30d).

[0070] In addition, in the electronic device 10 according to the present embodiment, the number of cores in the second cable 60 is smaller than the number of cores in the first cable 50 .

[0071] This makes it easier to reduce the weight of the entire electronic device 10.

[0072] Furthermore, in the electronic device 10 according to this embodiment, the first housing 20 is provided with a first connector 22 to which the first cable 50 is connected and a second connector 23 to which the second cable 60 is connected, and the first connector 22 and the second connector 23 have different shapes.

[0073] This makes it easier to use suitable cables for the first cable 50 and the second cable 60, respectively.

[0074] Furthermore, in the electronic device 10 according to this embodiment, the first connector 22 and the second connector 23 are arranged back to back, and the first housing 20 is formed so that the connection direction of the first cable 50 to the first connector 22 is the longitudinal direction.

[0075] This can prevent the first housing 20 from becoming large in size in a direction perpendicular to the direction in which the first cable 50 is connected to the first connector 22.

[0076] Furthermore, in the electronic device 10 according to this embodiment, the first housing 20 acquires necessity information regarding the necessity of supplying power to the jack 31a (31b, 31c, 31d) via the second cable 60, determines the necessity based on the necessity information, and supplies power via the first cable 50 if it determines that power supply is required.

[0077] This allows power to be supplied to the jack 31a (31b, 31c, 31d) when power needs to be supplied to the jack 31a (31b, 31c, 31d).

[0078] In addition, in electronic device 10 according to the present embodiment, there are a plurality of models of second housings (second housings 30a, 30b, 30c, 30d) in which jacks 31a, 31b, 31c, 31d have different shapes.

[0079] This allows audio signals to be output to a plurality of devices having plugs with different shapes.

[0080] In the electronic device 10 according to the present embodiment, the jacks 31a, 31b, 31c, and 31d include jacks that comply with the ARINC standard.

[0081] This allows audio signals to be output to devices that have plugs that comply with the ARINC standard.

[0083] In the above-described embodiment, the first position is inside the seat 90, and the second position is a position on the seat 90 that is exposed to the outside. However, this is not limiting. FIG. 8 is a schematic diagram showing an electronic device 110 according to another embodiment. The electronic device 110 differs from the electronic device 10 mainly in that the electronic device 110 includes a first cable 150 instead of the first cable 50. For example, as shown in FIG. 8, the jack 31a may be installed in a position exposed to the outside on a structure 190 installed in at least a portion of the periphery of the seat 90 where the user sits. The first housing 20 and the third housing 40 may also be installed inside the structure 190. The structure 190 is a wall installed to the side of the seat 90. The structure may be a table or the like installed to the side of the seat 90, or a wall or the like installed behind the seat 90. The second housing connected to the first cable 150 may be second housings 30b, 30c, or 30d of a model different from the second housing 30a. In this case, the jack provided in the second housing is installed at a position exposed to the outside of structure 190. Also, for example, the first position may be inside a seat different from the seat where the user sits (for example, a seat located near the seat where the user sits). Also, the second position may be an exposed position in a seat different from the seat where the user sits (for example, a seat located near the seat where the user sits). For example, a seat located near the seat where the user sits may be a seat next to the seat where the user sits, a seat in the row in front of the seat where the user sits, or a seat in the row behind the seat where the user sits.

[0084] In the above-described embodiment, a case where multiple models are present in the second housing has been described, but this is not limiting. For example, instead of multiple models, only one type of model may be present.
