Description

sound equipment

[0001] The present disclosure relates to an acoustic device installed in a moving body.

[0002] Patent Document 1 discloses an effect device that disables the function of a sound quality adjustment switch when it is detected that a headphone plug has been inserted into a headphone jack.

[0003] Japanese Patent Application Laid-Open No. 2002-108338

[0004] However, depending on the acoustic characteristics of an output device that outputs sound based on an acoustic signal, there are cases where it is better to output a corrected acoustic signal to the output device, and there are cases where it is better to output an uncorrected acoustic signal, and it is therefore desirable to output the acoustic signal more appropriately.

[0005] Therefore, the present disclosure provides an audio device that can output an audio signal more appropriately.

[0006] An acoustic device according to one aspect of the present disclosure is an acoustic device installed in a mobile body, having two or more jacks that output acoustic signals, and comprising: a jack unit used by a user sitting in a seat on the mobile body; an input receiving unit that receives input from the user sitting in the seat; a detection unit that detects that a plug of an output device that outputs sound based on the acoustic signal has been connected to the jack unit; a memory unit that stores a correction value for correcting the acoustic signal, the correction value being generated based on the acoustic characteristics of an output device distributed to the user using the mobile body; and a processor that, when the detection unit detects that one of the plugs has been connected to the jack unit, receives from the input receiving unit a selection of whether or not to correct the acoustic signal, and, when it is selected to correct the acoustic signal, outputs the acoustic signal corrected based on the correction value from the jack unit.

[0007] Furthermore, an acoustic device according to an aspect of the present disclosure is an acoustic device installed in a mobile body, the acoustic device having two or more jacks for outputting an acoustic signal, the acoustic device including: a jack unit used by a user sitting in a seat of the mobile body; an input receiving unit for receiving input from the user sitting in the seat; a detection unit for detecting that a plug of an output device that outputs sound based on the acoustic signal has been connected to the jack unit; a storage unit for storing the correction value for correcting the acoustic signal, the correction value being generated based on acoustic characteristics of an output device distributed to the user using the mobile body, and the number of the plugs of the output device distributed to the user using the mobile body; When the detection unit detects that a number of plugs different from the number of plugs of an output device distributed to a user have been connected to the jack unit, the detection unit outputs the acoustic signal that has not been corrected based on the correction value from the jack unit without accepting a selection of whether or not to correct the acoustic signal, and when the detection unit detects that a number of plugs identical to the number of plugs of an output device distributed to the user who uses the mobile object have been connected to the jack unit, the detection unit accepts the selection from the input acceptance unit, and if it is selected to correct the acoustic signal, the processor outputs the acoustic signal corrected based on the correction value from the jack unit.

[0008] These comprehensive or specific aspects may be realized as a system, a method, an integrated circuit, a computer program, or a computer-readable recording medium such as a CD-ROM, or may be realized as any combination of a system, a method, an integrated circuit, a computer program, and a recording medium. The recording medium may also be a non-transitory recording medium.

[0009] The audio device of the present disclosure can output audio signals more appropriately.

[0010] Further advantages and effects of one aspect of the present disclosure will become apparent from the specification and drawings. Such advantages and / or effects are provided by some of the embodiments and configurations described in the specification and drawings, but not necessarily all of the configurations.

[0011] FIG. 1 is a schematic diagram showing an acoustic device and the like according to a first embodiment. FIG. 2 is a front view showing the acoustic device of FIG. 1. FIG. 3 is a block diagram showing the functional configuration of the acoustic device of FIG. 1. FIG. 4 is a flowchart showing a first operation example of the acoustic device of FIG. 1. FIG. 5 is a first explanatory diagram for explaining the first operation example of FIG. 4. FIG. 6 is a second explanatory diagram for explaining the first operation example of FIG. 4. FIG. 7 is a flowchart showing a second operation example of the acoustic device of FIG. 1. FIG. 8 is a flowchart showing an operation example of an acoustic device according to a second embodiment.

[0012] An acoustic device according to one aspect of the present disclosure is an acoustic device installed in a mobile body, having two or more jacks that output acoustic signals, and comprising: a jack unit used by a user sitting in a seat on the mobile body; an input receiving unit that receives input from the user sitting in the seat; a detection unit that detects that a plug of an output device that outputs sound based on the acoustic signal has been connected to the jack unit; a memory unit that stores a correction value for correcting the acoustic signal, the correction value being generated based on the acoustic characteristics of an output device distributed to the user using the mobile body; and a processor that, when the detection unit detects that one of the plugs has been connected to the jack unit, receives from the input receiving unit a selection of whether or not to correct the acoustic signal, and, when it is selected to correct the acoustic signal, outputs the acoustic signal corrected based on the correction value from the jack unit.

[0013] According to this, when a single plug found in a playback device such as a commercially available earphone is connected to the jack, if the user selects to correct the audio signal, an audio signal corrected based on the correction value can be output from the jack. In this way, when a single plug found in a playback device such as a commercially available earphone is connected to the jack, an audio signal according to the user's intention can be output from the jack, so that the audio signal can be output more appropriately.

[0014] Furthermore, in an acoustic device according to one aspect of the present disclosure, when the detection unit detects that two or more of the plugs are connected to the jack unit, the processor may output the acoustic signal corrected based on the correction value from the jack unit without accepting the selection.

[0015] According to this, when two or more plugs found in playback devices such as earphones conforming to the ARINC standard, which are mainly distributed on airplanes, are connected to the jack, an audio signal corrected based on the correction value can be output from the jack without requiring the user to select whether or not to correct the audio signal. In this way, when two or more plugs found in earphones mainly distributed on airplanes are connected to the jack, a corrected audio signal can be output from the jack while minimizing the user's effort, allowing the audio signal to be output more appropriately.

[0016] In addition, in the acoustic device according to one aspect of the present disclosure, the jack portion may be capable of connecting to the plug conforming to the ARINC standard.

[0017] This allows audio signals to be output more appropriately to an output device having a plug that complies with the ARINC standard.

[0018] Furthermore, in an acoustic device according to one aspect of the present disclosure, when the detection unit detects that one of the plugs has been connected to the jack unit after the selection has been received from the input receiving unit, if the period between the first point in time at which the selection was received from the input receiving unit and the second point in time at which the detection unit detects that one of the plugs has been connected to the jack unit is less than a predetermined period, the processor may output the acoustic signal from the jack unit in accordance with the result of the selection received at the first point in time without receiving the selection.

[0019] According to this, when one plug is connected to the jack, the audio signal can be output from the jack in accordance with the result of the selection received at the first point in time, without having to again receive a selection of whether or not to correct the audio signal. In this way, when one plug is connected to the jack, the audio signal can be output from the jack in accordance with the user's intention while minimizing the user's effort, so the audio signal can be output more appropriately.

[0020] In addition, in an acoustic device according to one aspect of the present disclosure, the moving body is an aircraft, and when the detection unit detects that one of the plugs is connected to the jack unit and an announcement is being made on the moving body, the processor may receive the selection from the input receiving unit after the announcement has ended.

[0021] This makes it possible to accept the selection of whether or not to correct the acoustic signal while preventing the announcement from being interrupted.

[0022] In addition, in the acoustic device according to one aspect of the present disclosure, the moving body may be an aircraft, and the processor may accept the selection only once during one flight of the moving body.

[0023] This can reduce the inconvenience to the user caused by repeatedly having to select whether or not to correct the acoustic signal.

[0024] Furthermore, the audio device according to one aspect of the present disclosure may further include a display unit that displays video content, and the processor may not accept the selection when the video content is displayed on the display unit.

[0025] This makes it possible to accept the selection of whether or not to correct the audio signal while preventing the display of the video content from being hindered.

[0026] Furthermore, an acoustic device according to an aspect of the present disclosure is an acoustic device installed in a mobile body, the acoustic device having two or more jacks for outputting an acoustic signal, the acoustic device including: a jack unit used by a user sitting in a seat of the mobile body; an input receiving unit for receiving input from the user sitting in the seat; a detection unit for detecting that a plug of an output device that outputs sound based on the acoustic signal has been connected to the jack unit; a storage unit for storing the correction value for correcting the acoustic signal, the correction value being generated based on acoustic characteristics of an output device distributed to the user using the mobile body, and the number of the plugs of the output device distributed to the user using the mobile body; When the detection unit detects that a number of plugs different from the number of plugs of an output device distributed to a user have been connected to the jack unit, the detection unit outputs the acoustic signal that has not been corrected based on the correction value from the jack unit without accepting a selection of whether or not to correct the acoustic signal, and when the detection unit detects that a number of plugs identical to the number of plugs of an output device distributed to the user who uses the mobile object have been connected to the jack unit, the detection unit accepts the selection from the input acceptance unit, and if it is selected to correct the acoustic signal, the processor outputs the acoustic signal corrected based on the correction value from the jack unit.

[0027] According to this, when a number of plugs different from the number of plugs of the output device distributed to the user using the mobile object is connected to the jack, an audio signal that has not been corrected based on the correction value can be output from the jack without receiving a selection of whether or not to correct the audio signal. In this way, when a number of plugs different from the number of plugs of the output device distributed to the user using the mobile object is connected to the jack, an audio signal that has not been corrected based on the correction value can be output from the jack while minimizing the user's effort, thereby enabling more appropriate output of the audio signal. Furthermore, when a number of plugs equal to the number of plugs of the output device distributed to the user using the mobile object is connected to the jack, if the user selects to correct the audio signal, an audio signal corrected based on the correction value can be output from the jack. In this way, when a number of plugs equal to the number of plugs of the output device distributed to the user using the mobile object is connected to the jack, an audio signal according to the user's intention can be output from the jack, thereby enabling more appropriate output of the audio signal.

[0028] Hereinafter, the embodiments will be specifically described with reference to the drawings.

[0029] 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.

[0030] (First embodiment) Fig. 1 is a schematic diagram showing an acoustic device 10 according to a first embodiment. Fig. 2 is a front view showing the acoustic device 10 of Fig. 1. The configuration of the acoustic device 10 will be described with reference to Figs. 1 and 2.

[0031] The acoustic device 10 is installed in a moving object and outputs an acoustic signal. In this embodiment, the moving object is an aircraft. Note that the moving object does not have to be an aircraft, and may be, for example, a vehicle capable of carrying people, such as a car or a ship. The vehicle may be an automobile, a railroad car, or the like. As shown in FIG. 1 , in this embodiment, the acoustic device 10 is installed in a seat 20 installed inside the moving object.

[0032] The seats 20 have a seat 21 on which a user sits, legs 22 that support the seat 21, a backrest 23 that supports the user sitting on the seat 21 from behind, and an armrest 24 on which the user sitting on the seat 21 can rest their elbows, etc. An acoustic device 10 is installed on the back of the backrest 23 of each seat 20. While sitting in a seat 20, the user can use the acoustic device 10 installed on the backrest 23 of the seat 20 located in front of the seat 20. The user is a passenger or other occupant of a moving object.

[0033] As shown in FIG. 2, the audio device 10 includes a main body 11, a jack section 12, and a touch panel 13.

[0034] The main body 11 is attached to the rear surface of the backrest portion 23.

[0035] The jack unit 12 has two jacks 12a and 12b that output audio signals. The jack unit 12 is used by a user sitting in the seat 20 behind the seat 20 to which the main body 11 is attached. The jack unit 12 can connect to a plug that complies with the ARINC standard. For example, the jack unit 12 can connect to a plug that complies with the ARINC 628 standard. ARINC 628 is a standard related to interfaces for cabin equipment in aircraft. The jack unit 12 is provided on the main body 11.

[0036] Touch panel 13 is an example of an input receiving unit that receives input from a user sitting in seat 20. Touch panel 13 is also an example of a display unit that displays video content. Touch panel 13 receives input from a user sitting in seat 20 behind the seat 20 to which main body 11 is attached, and displays video content to the user. Touch panel 13 is provided on main body 11.

[0037] Fig. 3 is a block diagram showing the functional configuration of the audio device 10 of Fig. 1. The functional configuration of the audio device 10 will be described with reference to Fig. 3.

[0038] As shown in FIG. 3 , the acoustic device 10 further includes a detection unit 14 , a storage unit 15 , and a processor 16 .

[0039] The detection unit 14 detects that a plug of an output device is connected to the jack unit 12. The output device is a device that outputs sound based on an acoustic signal, and when the plug of the output device is connected to the jack unit 12, the output device outputs sound based on the acoustic signal output from the jack unit 12. The user can listen to the sound based on the acoustic signal through the output device. For example, the output device is a playback device that plays back sound, such as earphones or headphones. For example, the detection unit 14 is an infrared sensor, a sensor that can detect changes in current or voltage, or a physical switch. Note that the detection unit 14 is not limited to this, as long as it is hardware that can detect that a plug is connected to the jack unit 12.

[0040] The storage unit 15 stores correction values ​​and the like. The correction values ​​are values ​​for correcting acoustic signals and are generated based on the acoustic characteristics of an output device distributed to a user using a mobile object. Hereinafter, an output device distributed by an airline or the like to a user using a mobile object in a seat or the like may be referred to as a distributed device. For example, if a distributed device has acoustic characteristics such as a low output level in a specific frequency band, the correction value is a value for correcting an acoustic signal so as to increase the output level of that frequency band. By correcting an acoustic signal based on such a correction value, the output level of that frequency band of the sound output from the distributed device can be increased compared to when correction based on the correction value is not performed, thereby improving the sound quality of the sound output from the distributed device. The correction values ​​are generated in advance by a provider or the like who provides a service using a mobile object and stored in the storage unit 15.

[0041] When one plug is connected to the jack unit 12, it is highly likely that the plug is a playback device such as commercially available earphones that the user has brought into the vehicle. Since the correction values ​​stored in the storage unit 15 are generated based on the distributed device distributed to the user, it is preferable that the user can select whether or not to apply the correction values ​​to the output to the commercially available earphones.

[0042] Therefore, when the detection unit 14 detects that one plug has been connected to the jack unit 12, the processor 16 receives a selection from the touch panel 13 as to whether or not to correct the acoustic signal. For example, the processor 16 displays a touch button on the touch panel 13 to receive the selection. When the selection to correct the acoustic signal is made, the processor 16 outputs the acoustic signal corrected based on the correction value from the jack unit 12. For example, when the selection to correct the acoustic signal is made, the processor 16 transitions the acoustic device 10 to a mode in which the acoustic signal corrected based on the correction value is output from the jack unit 12. When the selection to output the acoustic signal is made, the processor 16 corrects the acoustic signal (for example, when the user selects music to play, etc., the acoustic signal for playing the music, etc.) based on the correction value and outputs the corrected signal from the jack unit 12. On the other hand, when the selection not to correct the acoustic signal is made, the processor 16 outputs the acoustic signal from the jack unit 12 without correction based on the correction value. For example, when it is selected not to correct the audio signal, the processor 16 transitions the audio device 10 to a mode in which an audio signal that has not been corrected based on the correction value is output from the jack unit 12, and when a user operation to output an audio signal is received, the processor 16 outputs the audio signal (for example, when the user selects music or the like that he or she wants to play, the audio signal for playing the music or the like) without correction based on the correction value from the jack unit 12. This makes it possible to apply a correction value according to the user's request when one plug is connected to the jack unit 12.

[0043] On the other hand, if two plugs are connected to jack portion 12, it is highly likely that the device is a distributed device such as earphones conforming to the ARINC standard that are distributed at seats 20, etc. Since the correction values ​​stored in storage portion 15 are generated based on the distributed device distributed to the user, it is preferable to be able to reduce the user's effort in applying the correction values.

[0044] Therefore, when the detection unit 14 detects that two plugs are connected to the jack unit 12, the processor 16 outputs an audio signal corrected based on the correction value from the jack unit 12 without accepting a selection of whether to correct the audio signal. For example, when the detection unit 14 detects that two plugs are connected to the jack unit 12, the processor 16 transitions the audio device 10 to a mode in which an audio signal corrected based on the correction value is output from the jack unit 12 without accepting a selection of whether to correct the audio signal, and when a user operation to output an audio signal is accepted, the processor 16 corrects the audio signal (for example, when the user selects music or the like to play, the audio signal for playing the music or the like) based on the correction value and outputs the corrected audio signal from the jack unit 12. This reduces the user's effort in applying the correction value when two plugs are connected to the jack unit 12.

[0045] When the detection unit 14 detects that one plug has been connected to the jack unit 12 after the processor 16 receives a selection from the touch panel 13 as to whether or not to correct the acoustic signal, and the period between a first time point at which the selection is received from the touch panel 13 and a second time point at which the detection unit 14 detects that one plug has been connected to the jack unit 12 is equal to or shorter than a predetermined period, the processor 16 may output the acoustic signal from the jack unit 12 in accordance with the result of the selection received at the first time point without receiving the selection. For example, when the selection to correct the acoustic signal is made at the first time point, the processor 16 transitions the acoustic device 10 to a mode in which an acoustic signal corrected based on a correction value is output from the jack unit 12, and the acoustic signal corrected based on the correction value is output from the jack unit 12. On the other hand, when the selection not to correct the acoustic signal is made at the first time point, the processor 16 transitions the acoustic device 10 to a mode in which an acoustic signal not corrected based on the correction value is output from the jack unit 12. This reduces the user's time and effort in repeatedly selecting whether or not to correct the output of the playback device.

[0046] For example, the predetermined period is generated in advance by a provider or the like who provides a service using a mobile object, and is stored in storage unit 15. The case where detection unit 14 detects that one plug is connected to jack unit 12 after a selection of whether or not to correct the acoustic signal is accepted using touch panel 13 means a case where, after a selection of whether or not to correct the acoustic signal is accepted from touch panel 13, a plug is unplugged from jack unit 12, and then one plug is connected to jack unit 12, or the like.

[0047] When the detection unit 14 detects that one plug has been connected to the jack unit 12 and an announcement is being made in the mobile object, the processor 16 may accept a selection of whether or not to correct the acoustic signal from the touch panel 13 after the announcement has ended. For example, when the detection unit 14 detects that one plug has been connected to the jack unit 12 and an announcement is being made in the mobile object, the processor 16 does not display a touch button on the touch panel 13, but displays a touch button on the touch panel 13 after the announcement has ended and accepts the selection. This makes it possible to accept a selection of whether or not to correct the acoustic signal at an appropriate timing without interrupting the announcement.

[0048] Note that the processor 16 may accept a selection of whether or not to correct the acoustic signal only once during one flight of the moving object. For example, even if the detection unit 14 detects that a plug has been connected to the jack unit 12 after accepting a selection of whether or not to correct the acoustic signal during one flight, the processor 16 does not display a touch button for accepting the selection on the touch panel 13. When the detection unit 14 detects that a plug has been connected to the jack unit 12 after accepting a selection of whether or not to correct the acoustic signal, the processor 16 may output an acoustic signal based on the result of the selection, or may output an acoustic signal from the jack unit 12 that has not been corrected based on the correction value. For example, the processor 16 recognizes the start and end of a flight from flight information. This reduces the user's effort of repeatedly selecting whether or not to correct the output of the playback device.

[0049] Processor 16 does not accept a selection of whether or not to correct the acoustic signal while video content is being displayed on touch panel 13. For example, when detection unit 14 detects that one plug has been connected to jack unit 12, processor 16 does not cause touch panel 13 to display touch buttons while video content is being displayed on touch panel 13. Note that processor 16 may cause touch buttons to be displayed on touch panel 13 and accept the selection after the display of the video content has finished.

[0050] Fig. 4 is a flowchart showing a first operation example of the acoustic device 10 of Fig. 1. Fig. 5 is a first explanatory diagram for explaining the first operation example of Fig. 4. Fig. 6 is a second explanatory diagram for explaining the first operation example of Fig. 4. The first operation example of the acoustic device 10 will be explained with reference to Figs. 4 to 6.

[0051] 4, the processor 16 determines whether or not a plug is connected to the jack section 12 (step S1). If the detection section 14 has not detected that a plug is connected to the jack section 12, the processor 16 determines that the plug is not connected to the jack section 12. On the other hand, if the detection section 14 has detected that a plug is connected to the jack section 12, the processor 16 determines that the plug is connected to the jack section 12.

[0052] If the plug is not connected to the jack section 12 (No in step S1), the processor 16 again determines whether the plug is connected to the jack section 12 (step S1).

[0053] When a plug is connected to the jack portion 12 (Yes in step S1), the processor 16 determines whether two plugs are connected to the jack portion 12 (step S2). When the detection portion 14 detects that two plugs are connected to the jack portion 12, the processor 16 determines that two plugs are connected to the jack portion 12. On the other hand, when the detection portion 14 detects that one plug is connected to the jack portion 12, the processor 16 determines that two plugs are not connected to the jack portion 12.

[0054] When two plugs are connected to the jack unit 12 (Yes in step S2), the processor 16 transitions to a mode in which an acoustic signal corrected based on the correction value is output from the jack unit 12 (step S3). For example, as shown in Fig. 5 , when two plugs are connected to the jack unit 12, the processor 16 transitions to a mode in which an acoustic signal corrected based on the correction value is output from the jack unit 12 without accepting a selection of whether or not to correct the acoustic signal, and outputs the acoustic signal corrected based on the correction value from the jack unit 12.

[0055] If the two plugs are not connected to the jack unit 12 (No in step S2), the processor 16 determines whether or not video content is being displayed (step S4).

[0056] If the video content is being displayed (Yes in step S4), the processor 16 ends the process.

[0057] If the video content is not being displayed (No in step S4), the processor 16 determines whether an announcement is being made (step S5).

[0058] If an announcement is being made (Yes in step S5), the processor 16 waits until the announcement ends (step S6), and after the announcement ends, accepts a selection of whether or not to correct the acoustic signal (step S7).

[0059] If no announcement is being made (No in step S5), the processor 16 accepts a selection as to whether or not to correct the acoustic signal (step S7).

[0060] For example, as shown in FIG. 6, when one plug is connected to the jack portion 12, the processor 16 accepts a selection from the touch panel 13 as to whether or not to correct the acoustic signal.

[0061] The processor 16 determines whether or not it has been selected to correct the acoustic signal (step S8).

[0062] If it is selected to correct the acoustic signal (Yes in step S8), the processor 16 transitions to a mode in which an acoustic signal corrected based on the correction value is output from the jack unit 12 (step S3).

[0063] If it is not selected to correct the acoustic signal (No in step S8), the processor 16 transitions to a mode in which an acoustic signal that has not been corrected based on the correction value is output from the jack unit 12 (step S9).

[0064] Fig. 7 is a flowchart showing a second operation example of the acoustic device 10 of Fig. 1. The second operation example of the acoustic device 10 will be described with reference to Fig. 7. The second operation example is an example of operation that occurs after the first point in time when a selection of whether or not to correct the acoustic signal is accepted.

[0065] As shown in FIG. 7, the processor 16 determines whether or not a plug is connected to the jack portion 12 (step S11).

[0066] If the plug is not connected to the jack section 12 (No in step S11), the processor 16 again determines whether the plug is connected to the jack section 12 (step S11).

[0067] If a plug is connected to the jack section 12 (Yes in step S11), the processor 16 determines whether two plugs are connected to the jack section 12 (step S12).

[0068] If two plugs are connected to the jack portion 12 (Yes in step S12), the processor 16 proceeds to step S3 described above.

[0069] If two plugs are not connected to the jack portion 12 (No in step S12), the processor 16 determines whether the period between the first point in time and the second point in time is within a predetermined period of time (step S13).

[0070] If the period between the first time point and the second time point is not within the predetermined period (No in step S13), the processor 16 proceeds to step S4 described above.

[0071] If the period between the first time point and the second time point is within a predetermined period (Yes in step S13), the processor 16 determines whether or not it was selected to correct the acoustic signal at the first time point (step S14).

[0072] If it is selected to correct the acoustic signal at the first point in time (Yes in step S14), the processor 16 transitions to a mode in which an acoustic signal corrected based on the correction value is output from the jack unit 12 (step S15).

[0073] If it is not selected to correct the acoustic signal at the first point in time (No in step S14), the processor 16 transitions to a mode in which an acoustic signal that has not been corrected based on the correction value is output from the jack portion 12 (step S16).

[0074] The acoustic device 10 has been described above.

[0075] Note that steps S3 to S6 may be omitted from the procedure.

[0076] The acoustic device 10 according to this embodiment is an acoustic device installed in a mobile body, and has two jacks 12a, 12b for outputting acoustic signals. The acoustic device is equipped with a jack unit 12 used by a user sitting in a seat 20 of the mobile body, a touch panel 13 for receiving input from the user sitting in the seat 20, a detection unit 14 for detecting that a plug of an output device that outputs sound based on the acoustic signal has been connected to the jack unit 12, a memory unit 15 for storing a correction value for correcting the acoustic signal, which is generated based on the acoustic characteristics of the output device distributed to the user using the mobile body, and a processor 16 for receiving, from the touch panel 13, a selection of whether or not to correct the acoustic signal when the detection unit 14 detects that one plug has been connected to the jack unit 12, and for outputting an acoustic signal corrected based on the correction value from the jack unit 12 when the selection of correcting the acoustic signal has been made, and

[0077] According to this, when a single plug found mainly in playback devices such as commercially available earphones is connected to jack unit 12, if the user selects to correct the audio signal, an audio signal corrected based on the correction value can be output from jack unit 12. In this way, when a single plug found mainly in playback devices such as commercially available earphones is connected to jack unit 12, an audio signal according to the user's intention can be output from jack unit 12, so that the audio signal can be output more appropriately.

[0078] Furthermore, in the acoustic device 10 according to this embodiment, when the detection unit 14 detects that two plugs are connected to the jack unit 12, the processor 16 outputs an acoustic signal corrected based on the correction value from the jack unit 12 without accepting a selection of whether or not to correct the acoustic signal.

[0079] According to this, when two plugs found in playback devices such as earphones conforming to the ARINC standard, which are mainly distributed on airplanes, are connected to the jack unit 12, an audio signal corrected based on the correction value can be output from the jack unit 12 without requiring a user to select whether or not to correct the audio signal. In this way, when two plugs found in earphones mainly distributed on airplanes are connected to the jack unit 12, a corrected audio signal can be output from the jack unit 12 while minimizing the user's effort, allowing the audio signal to be output more appropriately.

[0080] Furthermore, in the acoustic device 10 according to this embodiment, the jack section 12 can be connected to a plug that complies with the ARINC standard.

[0081] This allows audio signals to be output more appropriately to an output device having a plug that complies with the ARINC standard.

[0082] Furthermore, in the acoustic device 10 according to this embodiment, when the detection unit 14 detects that one plug has been connected to the jack unit 12 after receiving a selection from the touch panel 13 as to whether or not to correct the acoustic signal, and the period between the first point in time at which the selection was received from the touch panel 13 and the second point in time at which the detection unit 14 detects that one plug has been connected to the jack unit 12 is less than a predetermined period, the processor 16 outputs the acoustic signal from the jack unit 12 in accordance with the result of the selection received at the first point in time without receiving the selection.

[0083] According to this, when one plug is connected to the jack unit 12, the selection of whether or not to correct the acoustic signal does not need to be received again, and the acoustic signal can be output from the jack unit 12 in accordance with the result of the selection received at the first point in time. In this way, when one plug is connected to the jack unit 12, the acoustic signal can be output from the jack unit 12 in accordance with the user's intention while minimizing the user's effort, and the acoustic signal can be output more appropriately.

[0084] Furthermore, in the acoustic device 10 according to this embodiment, the moving body is an aircraft, and when the detection unit 14 detects that one plug has been connected to the jack unit 12 and an announcement is being made on the moving body, the processor 16 receives a selection from the touch panel 13 as to whether or not to correct the acoustic signal after the announcement has ended.

[0085] This makes it possible to accept the selection of whether or not to correct the acoustic signal while preventing the announcement from being interrupted.

[0086] Furthermore, in the acoustic device 10 according to this embodiment, the moving body is an aircraft, and the processor 16 accepts the selection of whether or not to correct the acoustic signal only once during one flight of the moving body.

[0087] This can reduce the inconvenience to the user caused by repeatedly having to select whether or not to correct the acoustic signal.

[0088] In addition, the audio device 10 according to this embodiment further includes a touch panel 13 that displays video content, and the processor 16 does not accept a selection of whether or not to correct the audio signal when video content is displayed on the touch panel 13.

[0089] This makes it possible to accept the selection of whether or not to correct the audio signal while preventing the display of the video content from being hindered.

[0090] Second Embodiment Fig. 8 is a flowchart showing an example of the operation of an audio device according to a second embodiment. The audio device according to the second embodiment will be described with reference to Fig. 8. The following description will focus on the differences from the audio device 10 according to the first embodiment.

[0091] The acoustic device according to this embodiment has a similar configuration to the acoustic device 10 .

[0092] In this embodiment, the storage unit 15 further stores the number of plugs of the distribution device.

[0093] Furthermore, in this embodiment, when the detection unit 14 detects that a number of plugs different from the number of plugs of the distribution device are connected to the jack unit 12, the processor 16 does not accept a selection of whether or not to correct the acoustic signal, and outputs an acoustic signal that has not been corrected based on the correction value from the jack unit 12. In this way, it is possible to reduce the effort required for the user to select a correction when a plug different from that of the distribution device is connected.

[0094] On the other hand, in this embodiment, when the detection unit 14 detects that the same number of plugs as the number of plugs of the distribution device are connected to the jack unit 12, the processor 16 receives a selection of whether or not to correct the acoustic signal from the touch panel 13. If it is selected to correct the acoustic signal, the processor 16 outputs an acoustic signal corrected based on the correction value from the jack unit 12. If it is selected not to correct the acoustic signal, the processor 16 outputs an acoustic signal that has not been corrected based on the correction value from the jack unit 12.

[0095] 8, when a plug is connected to the jack unit 12 (Yes in step S1), the processor 16 determines whether the same number of plugs as the number of the distributing devices are connected to the jack unit 12 (step S21). That is, the processor 16 determines whether the same number of plugs as the number of the distributing devices are connected to the jack unit 12.

[0096] If the processor 16 does not have the same number of plugs connected to the jack unit 12 as the distributed devices (No in step S21), it proceeds to step S9, and if the processor 16 has the same number of plugs connected to the jack unit 12 as the distributed devices (Yes in step S21), it proceeds to step S4.

[0097] The acoustic device according to the second embodiment has been described above.

[0098] The acoustic device according to this embodiment is an acoustic device installed in a mobile body, and has two or more jacks 12a, 12b that output acoustic signals, and includes a jack unit 12 used by a user sitting in a seat 20 of the mobile body, a touch panel 13 that receives input from the user sitting in the seat 20, a detection unit 14 that detects that a plug of an output device that outputs sound based on the acoustic signal has been connected to the jack unit 12, a storage unit 15 that stores a correction value that is generated based on the acoustic characteristics of the output device distributed to the user using the mobile body and is used to correct the acoustic signal, and an output device distributed to the user using the mobile body. When the detection unit 14 detects that a number of plugs different from the number of plugs of the output device are connected to the jack unit 12, the detection unit 14 outputs an acoustic signal that has not been corrected based on a correction value from the jack unit 12 without accepting a selection of whether or not to correct the acoustic signal, and when the detection unit 14 detects that the same number of plugs as the number of plugs of the output device distributed to the user who uses the mobile object are connected to the jack unit 12, the processor 16 accepts the selection from the touch panel 13 and, if it is selected to correct the acoustic signal, outputs an acoustic signal corrected based on the correction value from the jack unit 12.

[0099] According to this, when a number of plugs different from the number of plugs of the output device distributed to the user using the mobile object is connected to the jack unit 12, an acoustic signal that has not been corrected based on the correction value can be output from the jack unit 12 without receiving a selection of whether or not to correct the acoustic signal. In this way, when a number of plugs different from the number of plugs of the output device distributed to the user using the mobile object is connected to the jack unit 12, an acoustic signal that has not been corrected based on the correction value can be output from the jack unit 12 while minimizing the user's effort, thereby allowing the acoustic signal to be output more appropriately. Furthermore, when a number of plugs equal to the number of plugs of the output device distributed to the user using the mobile object is connected to the jack unit 12, if the user selects to correct the acoustic signal, an acoustic signal corrected based on the correction value can be output from the jack unit 12. In this way, when a number of plugs equal to the number of plugs of the output device distributed to the user using the mobile object is connected to the jack unit 12, an acoustic signal according to the user's intention can be output from the jack unit 12, allowing the acoustic signal to be output more appropriately.
