DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] <Embodiment> Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] <Outline of the sound output system> First, an overview of a sound output system according to an embodiment will be described.

[0012] A sound output system according to an embodiment includes a sound output device and an information processing device. Here, the sound output device is connected to the information processing device so as to be able to communicate with the information processing device. The sound output device also includes a wearing unit, a plurality of sound output units, and a control unit. The wearing unit wears the sound output device on a person's body. Each of the plurality of sound output units performs an operation of outputting information indicating a sound or a sound. Then, when the sound output device is connected to the information processing device, the control unit enables the operation of one or more first sound output units that are predetermined among the plurality of sound output units, and disables the operation of one or more sound output units other than the one or more first sound output units among the plurality of sound output units. Thereby, when the sound output device and the sound output system are connected to the information processing device, it is possible to suppress sound from being output from an unintended sound output unit.

[0013] The configuration of the sound output system according to the embodiment and the process performed by the sound output system when the sound output device is connected to an information processing device will be described in detail below.

[0014] <Sound output system configuration> First, the configuration of a sound output system according to an embodiment will be described by taking as an example the sound output system 1. For convenience of explanation, a user of the sound output system 1 will be simply referred to as a user below.

[0015] Fig. 1 is a schematic diagram showing an example of the configuration of a sound output system 1. Fig. 2 is a diagram showing an example of the configuration of a sound output device 10 provided in the sound output system 1. Fig. 3 is a diagram showing an example of the configuration of an information processing device 20 provided in the sound output system 1.

[0016] The sound output system 1 includes a sound output device 10 and an information processing device 20. Here, the sound output device 10 and the information processing device 20 are connected to each other in a wired or wireless manner so as to be able to communicate with each other.

[0017] The sound output system 1 causes the information processing device 20 to output sound information indicating a sound, and causes the sound output device 10 to output a sound indicated by the sound information output from the information processing device 20. In this way, the sound output system 1 allows the user to hear a sound that the user desires. Here, in this embodiment, the sound refers to voice, acoustics, music, etc., but is not limited to these. That is, in this embodiment, the sound may be a sound made by a living thing, or may be a sound made by an inanimate object. Also, in this embodiment, the sound information may be a signal indicating a sound, or may be other forms of information indicating a sound.

[0018] The sound output device 10 is an example of the above-mentioned sound output device. The sound output device 10 acquires sound information output from the information processing device 20. The sound output device 10 performs processing according to the acquired sound information. For example, the sound output device 10 performs processing to output a sound indicated by the acquired sound information. In this way, the sound output device 10 can make the user hear the sound. In addition, for example, the sound output device 10 performs processing to output the acquired sound information to another device capable of outputting the sound indicated by the sound information. The other device is, but is not limited to, an earphone, a headphone, or the like. In this way, the sound output device 10 can cause the other device to output the sound indicated by the sound information output from the information processing device 20.

[0019] Moreover, the sound output device 10 is a device that can be worn by a user. In the example shown in FIG. 1, the sound output device 10 is a head-mounted display. The head-mounted display is an example of a wearable display device. Instead of a head-mounted display, the sound output device 10 may be another type of wearable display device that can be worn by a user. Instead of a head-mounted display, the sound output device 10 may be a wearable device that cannot display images and can output sound. Examples of such devices include headphones.

[0020] The sound output device 10 also includes a plurality of sound output units that perform an operation of outputting sound information or sound. For this reason, the sound output device 10 can cause any one of the plurality of sound output units to output the sound indicated by the sound information acquired from the information processing device 20 or the sound information itself. Each of the plurality of sound output units is, for example, a cone-type speaker, a horn-type speaker, a ribbon-type speaker, a dome-type speaker, a bone conduction speaker, a device having a jack from which sound information is output, a device having a plug from which sound information is output, a communication device that outputs sound information wirelessly, and the like, but is not limited thereto. Note that some or all of the plurality of sound output units included in the sound output device 10 may be a sound input / output unit that is integrated with a sound input unit to which sound information is input. In this case, the sound input / output unit is, for example, a device in which any one of various speakers and a microphone are integrated, a communication device that inputs and outputs sound information wirelessly, and the like, but is not limited thereto. In the following, as an example, a case where the sound output device 10 includes two sound output units will be described. In the following, as an example, a case where each of the two sound output units is a sound input / output unit will be described. In the following, as an example, a case will be described in which the two sound input / output units are sound input / output unit 16A and sound input / output unit 16B. Note that the sound output device 10 may be configured to include three or more sound output units. In this case, some or all of the three or more sound output units may be sound input / output units.

[0021] 2, the sound output device 10 includes a control unit 11, a storage unit 12, an operation unit 13, a communication unit 14, a display unit 15, a sound input / output unit 16A, a sound input / output unit 16B, and a mounting unit 17. Note that in FIG. 1, the control unit 11, the storage unit 12, and the communication unit 14 are omitted to avoid cluttering the diagram.

[0022] The control unit 11 controls the entire sound output device 10. The control unit 11 is a processor, such as a microcomputer, a CPU (Central Processing Unit), or a DSP (Digital Signal Processor). The control unit 11 executes various programs stored in the storage unit 12. The control unit 11 may be configured with a plurality of hardware components, or may be configured with a single processor. The control unit 11 may also be hardware programmed to realize each function of the sound output device 10. That is, the control unit 11 may be configured to have the various programs stored in the storage unit 12 mounted as hardware circuits. In this case, for example, the control unit 11 is configured with an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or the like.

[0023] The storage unit 12 includes, for example, a solid state drive (SSD), an electrically erasable programmable read-only memory (EEPROM), a read-only memory (ROM), and a random access memory (RAM). The storage unit 12 may be an external storage device connected via a digital input / output port such as a universal serial bus (USB) instead of being built into the sound output device 10. The storage unit 12 stores various types of information, various programs, and the like that are processed by the sound output device 10. The storage unit 12 may be configured by one storage device or multiple storage devices.

[0024] The operation unit 13 has one or more hardware keys that accept various operations. The operation unit 13 has hardware keys that accept an operation to adjust the volume of the sound output from the sound output device 10, i.e., a volume, and a hardware key that accepts an operation to switch the power of the sound output device 10 on and off. The operation unit 13 may be configured to have other hardware keys instead of or in addition to these hardware keys. The sound output device 10 may be configured not to have the operation unit 13. In this case, the sound output device 10 accepts operations from an information processing device that is communicably connected to the sound output device 10. Here, the information processing device 20 is an example of such an information processing device. Even if the sound output device 10 has the operation unit 13, the sound output device 10 accepts operations from an information processing device that is communicably connected to the sound output device 10.

[0025] The communication unit 14 includes, for example, a digital input / output port such as a USB, an Ethernet (registered trademark) port, and the like.

[0026] The display unit 15 is a display device including a transmissive liquid crystal display. Instead of a transmissive liquid crystal display, the display unit 15 may be configured to include a display element such as another transmissive display, a liquid crystal display panel that outputs image light to a transmissive light guiding optical system and a light guiding optical system, or an organic EL (ElectroLuminescence) display panel. The display unit 15 is not limited to a transmissive type that transmits external light, and may be configured to block external light and allow the user to view only the image, or may be configured to superimpose an external world image captured by a camera on the image and allow the user to view it.

[0027] The sound input / output unit 16A is an example of a sound input / output unit in which a sound input unit to which sound information is input and a sound output unit that performs an operation of outputting sound information or sound are integrated. The sound input / output unit 16A is, for example, a built-in microphone and speaker integrated with the sound output device 10. In this case, the microphone is an example of a sound input unit to which sound information is input. In addition, in this case, the speaker is an example of a sound output unit that performs an operation of outputting sound. Note that this speaker may be any type of speaker. In addition, the sound output device 10 may be configured to include a built-in speaker integrated with the sound output device 10 as a sound output unit instead of the sound input / output unit 16A.

[0028] The sound input / output unit 16B is an example of a sound input / output unit in which a sound input unit to which sound information is input and a sound output unit that performs an operation of outputting sound information or sound are integrally configured. The sound input / output unit 16B is, for example, a device that has a jack and performs input / output of sound information via the jack and the plug when a plug is inserted into the jack. The plug is, for example, a plug that inputs sound information to earphones, headphones, etc., a plug that outputs sound information from a music playback device such as a CD player, etc., but is not limited to these. Note that the sound output device 10 may be configured to include a device that performs an operation of outputting sound information to the plug in this case as a sound output unit instead of the sound input / output unit 16B. Earphones, headphones, etc. are examples of the device.

[0029] The mounting unit 17 is a member used for mounting the sound output device 10 on the user's body. In the example shown in FIG. 1, the sound output device 10 is a head-mounted display as described above. In this case, the mounting unit 17 mounts the sound output device 10 on the user's head so that the user can view the display surface of the display unit 15. In this example, the mounting unit 17 is a temple. The mounting unit 17 may have a pad, end pieces, etc. in addition to the temple. Also, the mounting unit 17 may be any other member instead of a temple as long as it is a member capable of mounting the sound output device 10 on the user's head so that the user can view the display surface of the display unit 15.

[0030] Here, in the example shown in FIG. 1, the sound output device 10 is composed of two devices, a sound output device main body 10A and a relay device 10B. In this case, the sound output device main body 10A and the relay device 10B are connected to each other so that they can communicate with each other by wire or wirelessly. In this example, the sound output device main body 10A and the relay device 10B are connected to each other so that they can communicate with each other by a cable. In addition, the relay device 10B relays the transmission and reception of various information between the sound output device main body 10A and the information processing device 20. That is, in this example, the relay device 10B and the information processing device 20 are connected to each other so that they can communicate with each other by wire or wirelessly. As a result, in the example shown in FIG. 1, the sound output device 10 and the information processing device 20 are connected to each other so that they can communicate with each other, as described above.

[0031] 1, the sound output device main body 10A includes a control unit 11, a storage unit 12, a display unit 15, a sound input / output unit 16A, a sound input / output unit 16B, and a mounting unit 17. In this example, the relay device 10B includes an operation unit 13 and a communication unit 14. The sound output device main body 10A may further include at least one of the operation unit 13 and the communication unit 14. The relay device 10B may further include some or all of the control unit 11, the storage unit 12, the sound input / output unit 16A, and the sound input / output unit 16B. The sound output device 10 may be a device in which the sound output device main body 10A and the relay device 10B are integrated together.

[0032] The information processing device 20 is, for example, a multi-function mobile phone terminal (smartphone). Note that the information processing device 20 may be other information processing devices such as a mobile phone terminal, a tablet PC (Personal Computer), a notebook PC, a PDA (Personal Digital Assistant), a desktop PC, a workstation, etc., instead of a multi-function mobile phone terminal.

[0033] The information processing device 20 outputs various commands to the sound output device 10 to control the sound output device 10 in response to the received operation. The command output from the information processing device 20 to the sound output device 10 may be a command or another type of command. This allows the user to operate the sound output device 10 via the information processing device 20. In other words, the sound output device 10 can receive an operation from the information processing device 20.

[0034] Furthermore, the information processing device 20 can output various types of sound information to the sound output device 10 in response to the received operation, thereby allowing the sound output device 10 to output a sound desired by the user. These various types of sound information include, for example, information indicating music, voice, etc., accompanying a moving image reproduced in the information processing device 20, information indicating the voice of a voice call made using the information processing device 20, etc., but are not limited thereto.

[0035] Furthermore, the information processing device 20 can output sounds indicated by various types of sound information from a speaker provided in the information processing device 20 in response to the received operation.

[0036] The information processing device 20 includes a control unit 21, a storage unit 22, an input receiving unit 23, a communication unit 24, a display unit 25, and a sound input / output unit 26.

[0037] The control unit 21 controls the entire information processing device 20. The control unit 21 is a processor, for example, a CPU. The control unit 21 executes various programs stored in the storage unit 22. The control unit 21 may be configured with multiple pieces of hardware, or may be configured with a single processor. The control unit 21 may also be hardware programmed to realize each function of the information processing device 20. That is, the control unit 21 may be configured to have the various programs stored in the storage unit 22 mounted as hardware circuits. In this case, for example, the control unit 21 is configured with an ASIC, an FPGA, or the like.

[0038] The storage unit 22 includes, for example, an SSD, an EEPROM, a ROM, a RAM, etc. Note that the storage unit 22 may be an external storage device connected via a digital input / output port such as a USB, instead of being built into the information processing device 20. The storage unit 22 stores various information, various programs, etc. that are processed by the information processing device 20. Note that the storage unit 22 may be configured by one storage device or multiple storage devices.

[0039] The input reception unit 23 is, for example, a touch panel that is integrated with the display unit 25. Alternatively, the input reception unit 23 may be another input device separate from the display unit 25, such as a keyboard or a mouse.

[0040] The communication unit 24 includes, for example, a digital input / output port such as a USB, an Ethernet (registered trademark) port, and the like.

[0041] The display unit 25 is a display device including, for example, a liquid crystal display panel, an organic EL display panel, or the like.

[0042] The sound input / output unit 26 is a functional unit in which a sound input unit to which sound information is input and a sound output unit that performs an operation of outputting sound are integrally configured. For example, the sound input / output unit 26 is a built-in microphone and speaker that are integrally configured with the information processing device 20. In this case, the microphone is an example of the sound input unit. Also, in this case, the speaker is an example of the sound output unit that performs an operation of outputting sound. Note that this speaker may be any type of speaker. Also, the information processing device 20 may be configured to include a built-in speaker that is integrally configured with the information processing device 20 as a sound output unit instead of the sound input / output unit 26.

[0043] Here, in the sound output system 1, when the sound output device 10 is connected to the information processing device 20, the sound output device 10 enables the operation of one or more first sound output units that are predetermined among the multiple sound output units, and disables the operation of one or more sound output units other than the one or more first sound output units among the multiple sound output units. In this example, as described above, the sound output device 10 includes two sound input / output units, the sound input / output unit 16A and the sound input / output unit 16B, as the multiple sound output units. Therefore, in this example, when the sound output device 10 is connected to the information processing device 20, the sound output device 10 enables the operation of one of the sound input / output unit 16A and the sound input / output unit 16B as the operation of the predetermined first sound output unit, and disables the operation of the other of the sound input / output unit 16A and the sound input / output unit 16B. Thereby, when the sound output device 10 is connected to the information processing device 20, it is possible to suppress the sound output from an unintended sound input / output unit. Below, as an example, a case where the sound input / output unit 16A is the predetermined first sound output unit will be described. In addition, when the sound output device 10 includes three or more sound output units, when the sound output device 10 is connected to the information processing device 20, the operation of one or more predetermined sound output units among the three or more sound output units may be enabled as the operation of one or more first sound output units, and the operation of one or more sound output units other than the one or more first sound output units among the three or more sound output units may be disabled. However, in this case, the one or more first sound output units do not inhibit each other's operation during operation.

[0044] <Sound output in the sound output system> Hereinafter, the output of sound in the sound output system 1 will be described with reference to Fig. 4. Hereinafter, in the description of Fig. 4, for convenience of explanation, unless there is a need to distinguish between the output of sound information or sound, they will be collectively referred to as the output of sound. Also, for convenience of explanation, below, a state in which the sound output device 10 and the information processing device 20 are communicatively connected will be referred to as a connected state. Also, for convenience of explanation, below, a state in which the sound output device 10 and the information processing device 20 are not communicatively connected will be referred to as a non-connected state.

[0045] FIG. 4 is a diagram showing an example of the relationship between the validity or invalidity of the operations of the sound input / output units 16A and 16B and the sound input / output units that output sounds in the sound output system 1. In FIG.

[0046] As shown in FIG. 4, in the sound output system 1, the sound input / output unit that outputs sound is switched depending on whether the operation of the sound input / output unit 16A and the sound input / output unit 16B is enabled or disabled.

[0047] Here, case 1 shown in FIG. 4 shows a situation where both the sound input / output unit 16A and the sound input / output unit 16B are enabled, and a plug such as an earphone is inserted into the sound input / output unit 16B. In FIG. 4, the enabled operation is indicated by "Enable". In FIG. 4, the disabled operation is indicated by "Disable". In the sound output system 1 of case 1, it is not determined whether the sound is output by the sound input / output unit 16A or the sound input / output unit 16B. That is, in the sound output system 1 of case 1, the sound input / output unit that outputs the sound is undefined. In this case, the sound is output by either one or both of the sound input / output unit 16A and the sound input / output unit 16B. For this reason, in the sound output system 1 of case 1, the sound may be output by an unintended sound input / output unit. This is not desirable for the user of the sound output system 1. In FIG. 4, the plug is inserted into the sound input / output unit 16B is indicated by "CONNECT". Also, in FIG. 4, "DISCONNECT" indicates that the plug is not inserted into the sound input / output unit 16B.

[0048] 4 shows a situation in which both the sound input / output units 16A and 16B are in operation and a plug such as an earphone is not inserted into the sound input / output unit 16B. In the sound output system 1 in Case 2, sound is output by the sound input / output unit 16A. This is because a plug such as an earphone is not inserted into the sound input / output unit 16B.

[0049] 4 shows a situation in which the operation of sound input / output unit 16A is enabled, the operation of sound input / output unit 16B is disabled, and a plug such as an earphone is inserted into sound input / output unit 16B. In sound output system 1 in Case 3, sound is output by sound input / output unit 16A.

[0050] 4 shows a situation in which the operation of sound input / output unit 16A is enabled, the operation of sound input / output unit 16B is disabled, and a plug such as an earphone is not inserted into sound input / output unit 16B. In sound output system 1 in case 4, sound is also output by sound input / output unit 16A.

[0051] 4 shows a situation in which the operation of sound input / output unit 16A is disabled, the operation of sound input / output unit 16B is enabled, and a plug such as an earphone is inserted into sound input / output unit 16B. In sound output system 1 in Case 5, sound is output by sound input / output unit 16B.

[0052] 4 shows a situation in which the operation of sound input / output unit 16A is disabled, the operation of sound input / output unit 16B is enabled, and a plug such as an earphone is not inserted into sound input / output unit 16B. In sound output system 1 in case 6, sound is output by sound input / output unit 26 of information processing device 20. This is because the plug of the earphone is not inserted into sound input / output unit 16B.

[0053] 4 shows a situation in which the operations of both the sound input / output unit 16A and the sound input / output unit 16B are disabled, and an earphone plug is inserted into the sound input / output unit 16B. In the sound output system 1 of Case 7, sound is also output by the sound input / output unit 26 of the information processing device 20.

[0054] 4 shows a state in which the operations of both the sound input / output unit 16A and the sound input / output unit 16B are disabled, and a plug such as an earphone is not inserted into the sound input / output unit 16B. In the sound output system 1 of Case 8, sound is also output by the sound input / output unit 26 of the information processing device 20.

[0055] As described above, in the sound output system 1, the sound input / output unit that outputs sound is switched depending on whether the operation of the sound input / output unit 16A and the sound input / output unit 16B is enabled or disabled. If the sound output system 1 transitions from a non-connected state to a connected state when case 1 shown in Fig. 4 is realized, sound may be output from an unintended sound input / output unit. For example, if case 1 is realized, the sound output system 1 may output sound from both the sound input / output unit 16A and the sound input / output unit 16B when the sound output system 1 transitions from a non-connected state to a connected state.

[0056] Therefore, in the sound output system 1, the sound output device 10 is configured not to realize case 1. Specifically, as described above, when the sound output device 10 is connected to the information processing device 20, the sound output device 10 enables the operation of the sound input / output unit 16A as the operation of a predetermined first sound output unit, and disables the operation of the sound input / output unit 16B. This makes it possible to prevent the sound output device 10 from realizing case 1 when connected to the information processing device 20, and as a result, to prevent sound from being output from an unintended sound input / output unit.

[0057] <Enable / disable switching process performed by the sound output device when connected to the information processing device> Hereinafter, with reference to FIG. 5, the enable / disable switching process performed by the sound output device 10 when connected to the information processing device 20 will be described. Here, the enable / disable switching process is a process of switching between enable and disable of the operations of the sound input / output unit 16A and the sound input / output unit 16B among the processes performed by the sound output device 10. FIG. 5 is a diagram showing an example of the flow of the enable / disable switching process performed by the sound output device 10 when connected to the information processing device 20. In the following, as an example, a case where the power supply of each of the sound output device 10 and the information processing device 20 is switched on at a timing before the process of step S110 shown in FIG. 5 is performed will be described. In addition, in the following, as an example, a case where the sound output device main body 10A and the relay device 10B are connected to be able to communicate with each other at that timing will be described.

[0058] The control unit 11 waits until the sound output device 10 is connected to the information processing device 20 (step S110). In FIG. 5, the process of step S110 is indicated by "connected?". For example, when a wired or wireless communication between the sound output device main body 10A and the information processing device 20 via the relay device 10B is established, the control unit 11 determines that the sound output device 10 is connected to the information processing device 20. In other words, when a communication between the sound output device 10 and the information processing device 20 is established, the control unit 11 determines that the sound output device 10 is connected to the information processing device 20. On the other hand, when this communication is not established, for example, the control unit 11 determines that the sound output device 10 is not connected to the information processing device 20. Here, the control unit 11 may be configured to specify that a wired or wireless communication between the sound output device main body 10A and the information processing device 20 via the relay device 10B is established by a known method, or may be configured to specify by a method to be developed in the future. The control unit 11 may be configured to determine that the sound output device 10 is connected to the information processing device 20 by another method. For example, the control unit 11 may be configured to determine that the sound output device 10 is connected to the information processing device 20 when the control unit 11 acquires information indicating completion of connection output from the information processing device 20. The information is an example of a second command. The control unit 11 may be configured to determine that the sound output device 10 is connected to the information processing device 20 when the sound output device 10 detects that the sound output device 10 is connected to the information processing device 20. In this case, the sound output device 10 includes a detection unit that detects that the sound output device 10 is connected to the information processing device 20.

[0059] When the control unit 11 determines that the sound output device 10 is connected to the information processing device 20 (step S110-YES), it disables the operation of the sound input / output unit 16B (step S120). That is, the control unit 11 prohibits the output of sound from the sound input / output unit 16B in step S120. In FIG. 5, the process of step S120 is indicated by "disabling the sound input / output unit 16B." Note that the control unit 11 may perform the process of step S120 by hardware, such as stopping the supply of power to the sound input / output unit 16B by a switching element, or by software, such as stopping the output of sound information to the sound input / output unit 16B.

[0060] Next, the control unit 11 enables the operation of the sound input / output unit 16A as the operation of the first sound input / output unit determined in advance (step S130). That is, the control unit 11 permits the output of sound from the sound input / output unit 16A in step S130. In FIG. 5, the process of step S130 is indicated by "enabling the sound input / output unit 16B". The control unit 11 may perform the process of step S130 by hardware, such as starting the supply of power to the sound input / output unit 16A by a switching element, or by software, such as starting the output of sound information to the sound input / output unit 16A. The control unit 11 may be configured to perform the process of step S120 and the process of step S130 in parallel.

[0061] Next, the control unit 11 waits until it receives a switching command from the information processing device 20 (step S140). Here, the switching command is a command to specify either one of the sound input / output unit 16A and the sound input / output unit 16B included in the sound output device 10. The switching command is a command to enable the operation of the sound input / output unit specified by the switching command. For example, when the sound input / output unit specified by the switching command is the sound input / output unit 16B, the switching command is a command to enable the operation of the sound input / output unit 16B. Also, for example, when the sound input / output unit specified by the switching command is the sound input / output unit 16A, the switching command is a command to enable the operation of the sound input / output unit 16A. Note that, when the sound output device 10 includes three or more sound input / output units, the switching command is a command to specify any one of these three or more sound input / output units, and is a command to enable the operation of the sound input / output unit specified by the switching command.

[0062] When the control unit 11 determines that a switching command has been received from the information processing device 20 (step S140-YES), it identifies whether the state of the information processing device 20 is a voice call state, a sound input / output state, or a non-sound input / output state (step S150). In FIG. 5, the process of step S150 is indicated by "identification of state of information processing device". Here, the voice call state is a state in which a voice call is being made among the states of the information processing device 20. The sound input / output state is a state different from the voice call state among the states of the information processing device 20, and is a state in which the information processing device 20 is making input / output of sound other than the voice call. Note that the input / output of sound also includes input / output of sound information. For example, the sound input / output state is a state in which the information processing device 20 is making a part or all of the reproduction of moving images, reproduction of music, recording, etc., which are accompanied by sound output. The non-sound input / output state is a state different from both the voice call state and the sound input / output state. In other words, the non-sound input / output state is a state in which a voice call is not being made among the states of the information processing device 20, and sound input / output other than the voice call is not being made.

[0063] Next, the control unit 11 performs a process according to the state of the information processing device 20 identified in step S150 (step S160). In Fig. 5, the process of step S160 is indicated by "process according to state." Here, the process of step S160 will be described.

[0064] For example, when the state of the information processing device 20 identified in step S150 is a voice call state, the control unit 11 performs a process of muting the volume of the sound output from each of the sound input / output units 16A and 16B as a process corresponding to the voice call state. This is because when the sound output device 10 and the information processing device 20 are connected while a voice call is being made in the information processing device 20, unless the volume of the sound output from each of the sound input / output units 16A and 16B is muted, the sound of the voice call in the information processing device 20 may be unintentionally output from either the sound input / output unit 16A or the sound input / output unit 16B. To prevent this, when the state of the information processing device 20 identified in step S150 is a voice call state, the control unit 11 performs a process of muting the volume of the sound output from each of the sound input / output units 16A and 16B.

[0065] Also, for example, when the state of the information processing device 20 identified in step S150 is a sound input / output state, the control unit 11 performs a process of stopping sound input / output by the information processing device 20 as a process according to the sound input / output state. Specifically, when music, moving images, or the like is being played by the information processing device 20, the control unit 11 performs a process of stopping the playback in step S160. Also, when recording is being performed by the information processing device 20, the control unit 11 performs a process of stopping the recording in step S160. This is because sound may be output from an unintended sound input / output unit before the user enables the operation of a desired sound input / output unit in the sound output device 10.

[0066] Also, for example, when the state of the information processing device 20 identified in step S150 is a non-sound input / output state, the control unit 11 does not perform processing corresponding to the non-sound input / output state in step S160.

[0067] After the processing of step S160 is performed, the control unit 11 disables the operation of both the sound input / output unit 16A and the sound input / output unit 16B (step S170). In FIG. 5, the processing of step S170 is indicated by "disable". Note that, in a case where the sound output device 10 has three or more sound input / output units, the control unit 11 disables the operation of all of these three or more sound input / output units in step S170. The processing of step S170 is a processing for more reliably preventing the above-mentioned case 1 from unintentionally occurring when switching between enabling and disabling the operation of each of the sound input / output unit 16A and the sound input / output unit 16B.

[0068] For example, when the control unit 11 performs the process of step S170 to transition the state from case 3 to case 5, the control unit 11 transitions the state from case 3 to case 7, and then transitions the state from case 7 to case 5, as shown in FIG. 6. FIG. 6 is a diagram showing an example of an image of a state transition through the process of step S170. Here, case 3 shown in FIG. 6 represents case 3 shown in FIG. 4. Moreover, case 5 shown in FIG. 6 represents case 5 shown in FIG. 4. Moreover, case 7 shown in FIG. 6 represents case 7 shown in FIG. 4. That is, when the control unit 11 transitions from a state in which the sound input / output unit that outputs sound is sound input / output unit 16A to a state in which the sound input / output unit that outputs sound is sound input / output unit 16B, the control unit 11 transitions from a state in which the sound input / output unit that outputs sound is sound input / output unit 16A to a state in which the sound input / output unit that outputs sound is sound input / output unit 26 by processing in step S170, and then transitions from the state in which the sound input / output unit that outputs sound is sound input / output unit 26 to a state in which the sound input / output unit that outputs sound is sound input / output unit 16B. This allows the sound output device 10 to more reliably prevent case 1 from occurring unintentionally.

[0069] Next, the control unit 11 enables the operation of the sound input / output unit designated by the switching command received in step S140 (step S180). In FIG. 5, the process of step S180 is indicated by "activation according to the switching command". For example, when the sound input / output unit designated by the switching command received in step S140 is the sound input / output unit 16B, the control unit 11 enables the operation of the sound input / output unit 16B. Also, for example, when the sound input / output unit designated by the switching command is the sound input / output unit 16A, the control unit 11 enables the operation of the sound input / output unit 16A. This allows the user of the sound output device 10 to enable the operation of a desired sound input / output unit via the information processing device 20 after connecting the sound output device 10 to the information processing device 20. After the process of step S180 is performed, the control unit 11 transitions to step S140 and waits again until a switching command is received from the information processing device 20.

[0070] As described above, when the sound output device 10 is connected to the information processing device 20, the sound output device 10 enables the operation of the sound input / output unit 16A of the two sound input / output units as the operation of a predetermined first sound input / output unit, and disables the operation of the sound input / output unit 16B. This makes it possible for the sound output device 10 to suppress output of sound from an unintended sound input / output unit when connected to the information processing device 20.

[0071] Furthermore, when connected to the information processing device 20, the sound output device 10 enables the operation of the sound input / output unit 16A and disables the operation of the sound input / output unit 16B, and then enables the operation of the sound input / output unit specified by the switching command in response to the received switching command. As a result, after being connected to the information processing device 20, the sound output device 10 can switch the sound input / output unit that outputs sound to the sound input / output unit desired by the user in response to an operation received from the user.

[0072] In addition, when the sound output device 10 enables the operation of either the sound input / output unit 16A or the sound input / output unit 16B in response to a switching command, the sound output device 10 disables the operations of both the sound input / output unit 16A and the sound input / output unit 16B before enabling the operation of the sound output unit, and then enables the operation of the sound input / output unit. For example, as shown in FIG. 6, when switching from case 3 to case 5 in response to a switching command, the sound output device 10 switches from case 3 to case 7, and then switches from case 7 to case 5. An example of a process for realizing this case 7 is the process of step S170 shown in FIG. 5. This makes it possible for the sound output device 10 to more reliably suppress unintentional realization of case 1 when switching between enabling and disabling the operations of each of the two sound input / output units.

[0073] Furthermore, when enabling the operation of either the sound input / output unit 16A or the sound input / output unit 16B in response to a switching command, the sound output device 10 performs processing according to the state of the information processing device 20 before enabling the operation of the sound output unit, and then disables the operations of both the sound input / output unit 16A and the sound input / output unit 16B, and then enables the operation of the sound input / output unit. This allows the sound output device 10 to more reliably prevent unintended sound from being output from both the sound input / output unit 16A and the sound input / output unit 16B.

[0074] <Processing performed by the information processing device when a switching operation is accepted> Hereinafter, with reference to FIG. 7, a process performed by the information processing device 20 when a switching operation is received will be described. Here, the switching operation is an operation of enabling the operation of one of the sound input / output unit 16A and the sound input / output unit 16B and disabling the operation of the other of the sound input / output unit 16A and the sound input / output unit 16B. FIG. 7 is a diagram showing an example of a flow of a process performed by the information processing device 20 when a switching operation is received. In the following, as an example, a case where the process of step S130 shown in FIG. 5 is performed at a timing before the process of step S210 shown in FIG. 7 is performed will be described. In addition, in the following, as an example, a case where an operation image P1 including an area RA in which an image for receiving an operation to the sound output device 10 is displayed is displayed on the display unit 25 of the information processing device 20 at that timing will be described.

[0075] The control unit 21 waits until a switching operation is received (step S210). Here, the process of step S210 will be described.

[0076] FIG. 8 is a diagram showing an example of the operation image P1. The operation image P1 includes an area RA. In the area RA, an image showing a sound input / output unit whose operation is enabled in the current sound output device 10 is displayed as an example of an image for accepting an operation on the sound output device 10. That is, immediately after the processing of step S130 shown in FIG. 5 is performed, an image P11 showing the sound input / output unit 16A which is the first sound input / output unit in this example is displayed in the area RA. When an operation to select the image P11 is performed, the control unit 21 accepts the operation as a switching operation for enabling the operation of the sound input / output unit 16B and disabling the operation of the sound input / output unit 16A. Then, the control unit 21 switches the image P11 to an image P12 showing the sound input / output unit 16B as shown in FIG. 9. That is, in this case, the image P12 is displayed in the area RA as shown in FIG. 9. FIG. 9 is a diagram showing an example of the operation image P1 when the image P12 is displayed. On the other hand, when an operation to select image P12 is performed, the control unit 21 accepts the operation as a switching operation to enable the operation of the sound input / output unit 16A and disable the operation of the sound input / output unit 16B. Then, the control unit 21 switches the image P12 to the image P11 indicating the sound input / output unit 16A as shown in Fig. 8. Note that the operation to select each of the images P11 and P12 is, for example, a touch operation such as tapping, clicking, etc., but is not limited to these.

[0077] When the control unit 21 determines that a switching operation has been received (step S210-YES), the control unit 21 outputs a switching command to the sound output device 10 (step S220). Here, if the switching operation received by the control unit 21 is a switching operation for enabling the operation of the sound input / output unit 16B, the control unit 21, in step S220, specifies the sound input / output unit 16B and outputs a switching command for enabling the operation of the sound input / output unit 16B to the sound output device 10. On the other hand, if the switching operation received by the control unit 21 is a switching operation for enabling the operation of the sound input / output unit 16A, the control unit 21, in step S220, specifies the sound input / output unit 16A and outputs a switching command for enabling the operation of the sound input / output unit 16A to the sound output device 10.

[0078] Next, the control unit 21 switches the image displayed in the area RA (step S230). Here, if the switching operation received in step S210 is an operation to select the image P11, the control unit 21 switches the image P11 displayed in the area RA to the image P12 in step S230. On the other hand, if the switching operation received in step S210 is an operation to select the image P12, the control unit 21 switches the image P12 displayed in the area RA to the image P11 in step S230. After the process of step S230 is performed, the control unit 21 transitions to step S210 and waits again until a switching operation is received.

[0079] As described above, the information processing device 20 can receive a switching operation to the sound output device 10. More specifically, the information processing device 20 can receive a switching operation and enable the operation of any of the sound input / output units included in the sound output device 10 in accordance with the received switching operation. This allows the information processing device 20 to enable the operation of the sound input / output unit desired by the user among the sound input / output units included in the sound output device 10.

[0080] <Processing performed by the sound output device when a predetermined storage start condition is satisfied> Hereinafter, a process performed by the sound output device 10 when a predetermined storage start condition is satisfied will be described with reference to Fig. 10. Here, the storage start condition is a condition that causes the sound output device 10 to start storing volume information indicating the volume of the sound. The storage start condition includes, for example, the following five conditions A1 to A5.

[0081] (Condition A1): The communication connection between the sound output device 10 and the information processing device 20 is disconnected. (Condition A2): The power supply of the information processing device 20 connected to the sound output device 10 is switched off. (Condition A3): When the operation of the sound input / output unit 16B is enabled, the plug is removed from the jack of the sound input / output unit 16B. (Condition A4): The operation of the sound input / output unit 16A is switched from enabled to disabled. (Condition A5): The operation of the sound input / output unit 16B is switched from enabled to disabled.

[0082] The storage start condition may include other conditions instead of some or all of the five conditions A1 to A5, or in addition to some or all of the five conditions. For example, when at least one of the five conditions included in the storage start condition is satisfied, the control unit 11 determines that the storage start condition is satisfied. On the other hand, for example, when all of the five conditions included in the storage start condition are not satisfied, the control unit 11 determines that the storage start condition is not satisfied.

[0083] FIG. 10 is a diagram showing an example of the flow of processing performed by the sound output device 10 when a predetermined storage start condition is satisfied.

[0084] The control unit 11 waits until the storage start condition is satisfied (step S310).

[0085] When the control unit 11 determines that the storage start condition is satisfied (step S310-YES), it identifies the sound input / output unit 16A or the sound input / output unit 16B, whichever is enabled. Then, the control unit 11 identifies the volume of the sound output from the identified sound input / output unit (step S320). For example, when the control unit 11 identifies that the sound input / output unit 16A is enabled in step S320, it identifies the volume of the sound output from the sound input / output unit 16A. Also, for example, when the control unit 11 identifies that the sound input / output unit 16B is enabled in step S320, it identifies the volume of the sound output from a device having a plug inserted into the sound input / output unit 16B.

[0086] Next, the control unit 11 generates volume information (step S330). Here, for example, if the sound input / output unit identified in step S320 is the sound input / output unit 16A, the control unit 11 generates information including information indicating the volume identified in step S320 and information identifying the sound input / output unit 16A as the volume information indicating the volume. Also, for example, if the sound input / output unit identified in step S320 is the sound input / output unit 16B, the control unit 11 generates information including information indicating the volume identified in step S320 and information identifying the sound input / output unit 16B as the volume information indicating the volume.

[0087] Next, the control unit 11 stores the volume information generated in step S330 in the storage unit 12 (step S340). When the control unit 11 stores volume information including information identifying the sound input / output unit 16A in the storage unit 12, if the volume information is pre-stored in the storage unit 12, the control unit 11 updates the volume information to new volume information. When the control unit 11 stores volume information including information identifying the sound input / output unit 16B in the storage unit 12, if the volume information is pre-stored in the storage unit 12, the control unit 11 updates the volume information to new volume information. After the process of step S340 is performed, the control unit 11 transitions to step S310 and waits again until the storage start condition is satisfied.

[0088] As described above, the sound output device 10 can store volume information every time a predetermined storage start condition is satisfied. As a result, the sound output device 10 can set the volume of the sound output from each of the sound input / output units 16A and 16B to the same volume as the volume previously set by the user without receiving any operation from the user, every time a read-out start condition described later is satisfied, by the process of the flowchart shown in FIG.

[0089] <Processing performed by the sound output device when a specific readout start condition is satisfied> Hereinafter, a process performed by the sound output device 10 when a predetermined read start condition is satisfied will be described with reference to Fig. 11. Here, the read start condition is a condition that causes the sound output device 10 to start reading out, from the storage unit 12, volume information that has been stored in advance in the storage unit 12. The read start condition includes, for example, the following five conditions, Condition B1 to Condition B5.

[0090] (Condition B1): The sound output device 10 is connected to the information processing device 20. (Condition B2): The power of the information processing device 20 connected to the sound output device 10 is switched on. (Condition B3): When the operation of the sound input / output unit 16B is enabled, a plug is inserted into the jack of the sound input / output unit 16B. (Condition B4): The operation of the sound input / output unit 16A is switched from disabled to enabled. (Condition B5): The operation of the sound input / output unit 16B is switched from disabled to enabled.

[0091] The read start condition may include other conditions instead of some or all of the five conditions B1 to B5, or in addition to some or all of the five conditions. The control unit 11 determines that the read start condition is satisfied when at least one of the five conditions included in the read start condition is satisfied. On the other hand, the control unit 11 determines that the read start condition is not satisfied when all of the five conditions included in the read start condition are not satisfied.

[0092] FIG. 11 is a diagram showing an example of the flow of processing performed by the sound output device 10 when a predetermined read start condition is satisfied.

[0093] The control unit 11 waits until the read start condition is satisfied (step S410).

[0094] When the control unit 11 determines that the readout start condition is satisfied (step S410-YES), it identifies the sound input / output unit 16A or the sound input / output unit 16B, whichever is enabled. Then, the control unit 11 reads volume information including information identifying the identified sound input / output unit from the storage unit 12 (step S420). For example, when the control unit 11 identifies that the sound input / output unit 16A is enabled in step S420, it reads volume information including information identifying the sound input / output unit 16A from the storage unit 12. Also, for example, when the control unit 11 identifies that the sound input / output unit 16B is enabled in step S320, it reads volume information including information identifying the sound input / output unit 16B from the storage unit 12. Note that, before the processing of the flowchart shown in FIG. 10 is performed, the storage unit 12 may store volume information including information indicating a default volume as the volume of the sound output from the sound input / output unit 16A together with information identifying the sound input / output unit 16A, or the volume information may not be stored. In addition, before the processing of the flowchart shown in Figure 10 is performed, the memory unit 12 may store volume information including information indicating a default volume as the volume of the sound output from the sound input / output unit 16B, together with information identifying the sound input / output unit 16B, or the volume information may not be stored.

[0095] Next, the control unit 11 specifies the volume indicated by the volume information read in step S420 (step S430).

[0096] Next, the control unit 11 sets the volume of the sound output from the sound input / output unit indicated by the information included in the volume information read in step S420 to the volume indicated by the information included in the volume information (step S440). Here, for example, if the sound input / output unit identified by the information included in the volume information read in step S420 is the sound input / output unit 16A, the control unit 11 sets the volume of the sound output from the sound input / output unit 16A to the volume specified in step S430. Also, for example, if the sound input / output unit identified by the information included in the volume information read in step S420 is the sound input / output unit 16B, the control unit 11 sets the volume of the sound output from the sound input / output unit 16B to the volume specified in step S430. After the process of step S440 is performed, the control unit 11 transitions to step S410 and waits again until the read start condition is satisfied.

[0097] As described above, each time a specified read-out start condition is satisfied, the sound output device 10 can set the volume of the sound output from each of the sound input / output units 16A and 16B to the same volume as the volume previously set by the user, without accepting any operation from the user.

[0098] As described above, the sound output device according to the embodiment is a sound output device that is communicably connected to an information processing device, and includes a mounting unit that mounts the sound output device on a human body, a plurality of sound output units that perform an operation of outputting information or sound indicating a sound, and a control unit that enables the operation of one or more first sound output units that are predetermined among the plurality of sound output units and disables the operation of one or more sound output units other than the one or more first sound output units among the plurality of sound output units when the sound output device is connected to the information processing device. Thereby, when the sound output device is connected to the information processing device, it is possible to suppress the sound output from an unintended sound output unit. Here, in the example described above, the sound output device 10 is an example of the sound output device. Also, in the example described above, the information processing device 20 is an example of the information processing device. Also, in the example described above, the mounting unit 17 is an example of the mounting unit. Also, in the example described above, each of the sound input / output unit 16A and the sound input / output unit 16B is an example of a sound output unit. Also, in the example described above, the sound input / output unit 16A is an example of a first sound output unit. In the example described above, the control unit 11 is an example of the control unit.

[0103] In addition, in the sound output device, the control unit may be configured, when connected to an information processing device, to enable operation of one or more first sound output units and disable operation of one or more sound output units in response to a second command received from the information processing device.

[0104] In addition, the sound output device may be configured to include a detection unit that detects that an information processing device has been connected, and when the detection unit detects that a connection has been made to the information processing device, the control unit enables operation of one or more first sound output units and disables operation of one or more sound output units.

[0105] In addition, in the sound output device, a configuration may be used in which the multiple sound output sections have a jack and, when a plug is inserted into the jack, include a device that outputs information indicating a sound to the plug, and a speaker that outputs sound.

[0106] The sound output device may be a wearable display device further including a display unit for displaying an image. In the above-described example, the wearable display device is a head-mounted display.

[0107] Although an embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and may be changed, replaced, deleted, etc. without departing from the gist of the present invention.

[0108] In addition, a program for realizing the function of any of the components in the above-described device may be recorded in a computer-readable recording medium, and the program may be read and executed by a computer system. The device may be, for example, the sound output device 10, the sound output device main body 10A, the relay device 10B, the information processing device 20, etc. Note that the "computer system" referred to here includes hardware such as an OS (Operating System) and peripheral devices. Furthermore, the "computer-readable recording medium" refers to portable media such as a flexible disk, a magneto-optical disk, a ROM, a CD (Compact Disk)-ROM, and a storage device such as a hard disk built into a computer system. Furthermore, the "computer-readable recording medium" refers to a storage device that holds a program for a certain period of time, such as a volatile memory (RAM) inside a computer system that becomes a server or a client when a program is transmitted via a network such as the Internet or a communication line such as a telephone line.

[0109] The above program may be transmitted from a computer system in which the program is stored in a storage device or the like to another computer system via a transmission medium, or by transmission waves in the transmission medium. Here, the "transmission medium" that transmits the program refers to a medium that has the function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. The above program may be for implementing some of the above functions. Furthermore, the above program may be a so-called differential file (differential program) that can implement the above functions in combination with a program already recorded in the computer system.
