[0091] Hereinafter, an embodiment will be described in detail with reference to the drawings. In the following description, like components are denoted by like reference numerals.

[0092] Overall Structure

[0093] The structure of a sound playing apparatus 1 according to one embodiment will be described with reference to Figure 1 and Figure 2 The sound playing apparatus 1 is an apparatus that outputs sound. In addition, the sound playing apparatus 1 has a time counting function (clock function) that counts time. In the present embodiment, the sound playing apparatus 1 is used by being disposed on a setting surface such as a table, a floor, a shelf, or a bedside table during a user's sleep. Specifically, the sound playing apparatus 1 is, for example, a table clock, a music player, a television, a game apparatus, or a monitoring apparatus. In particular, in the present embodiment, the sound playing apparatus 1 is an alarm clock for waking up a user who sleeps in front of the sound playing apparatus 1.

[0094] Figure 1 is a perspective view schematically showing the sound playing apparatus 1. As shown in Figure 1 ​As shown, the sound playback device 1 includes a main body 10, a display 11 disposed on the main body 10, and an operation unit 20 disposed on the upper part of the main body 10. In this embodiment, as... Figure 1 As shown, the main body 10 is configured as a cylindrical shell. However, the main body 10 can be configured as any three-dimensional shape such as a cuboid or a semi-cylindrical shape.

[0095] The display 11 is positioned on the front surface of the main body 10 in a manner that allows the user to visually confirm it from the front. The display 11 displays, for example, the current time. The current time can be displayed digitally or by the use of a long and short hand. Furthermore, as long as the user can recognize the current time and the alarm time (described later), the sound playback device 1 may not have a display 11; for example, it may have hands such as long and short hands and a clock face.

[0096] The operation unit 20 is a component used by a user to operate various functions of the sound playback device 1. In this embodiment, the operation unit 20 is a generally cylindrical component disposed above the main body 10. The operation unit 20 is installed so that it can be pressed into the main body 10 and rotated. When the user presses the operation unit 20 into the main body 10 or rotates the operation unit 20 relative to the main body 10, various functions of the sound playback device 1 can be operated. Furthermore, any component can be used as the operation unit 20 as long as it can operate various functions of the sound playback device 1. Therefore, the operation unit 20 can be, for example, a button, a switch, a cross key, a touch panel disposed on the screen of the display 11, etc.

[0097] Figure 2 This is a block diagram that schematically illustrates the component structure of the sound playback device 1. (For example...) Figure 2 As shown, the sound playback device 1 includes a display 11, a speaker 12, a non-contact sensor 21, an operation sensor 22, and a control unit 30. The display 11, speaker 12, non-contact sensor 21, and operation sensor 22 are electrically connected to the control unit 30 via signal lines. In addition, the sound playback device 1 also includes a battery (not shown) that supplies power to the display 11 and the control unit 30. In this embodiment, the display 11, speaker 12, non-contact sensor 21, operation sensor 22, and control unit 30 are housed within the main body 10, but some of them may not be housed within the main body 10.

[0098] Display 11 is an example of an image display used to display images. Display 11 is electrically connected to control unit 30 and is a device for displaying images according to image signals received from control unit 30. Display 11 displays images following a computer program executed by control unit 30. Display 11 is, for example, a liquid crystal display, an EL (Electroluminescence) display, or a plasma display.

[0099] The speaker 12 is an example of a sound generator for generating sound. The speaker 12 is electrically connected to the control section 30, and generates sound in accordance with a sound signal from the control section 30. The speaker 12 generates sound in accordance with a computer program executed by the control section 30.

[0100] The non-contact sensor 21 is a detection section that detects an object in a detection range in a non-contact manner. The non-contact sensor 21 is capable of detecting the distance of an object in the detection range, the direction in which the object is located with respect to the non-contact sensor 21, and the speed of the object in a time series in a non-contact manner. In the present embodiment, the non-contact sensor 21 is disposed at the front of the main body 10, and detects an object in a detection range in front of the sound playback device 1. In particular, in the present embodiment, the non-contact sensor 21 detects at least any one of the distance of an object, the direction in which the object is located, and the speed of the object in a time series. The non-contact sensor 21, for example, outputs an output signal indicating an object in the detection range. The output signal from the non-contact sensor 21 is input to the control section 30.

[0101] In the present embodiment, the non-contact sensor 21 is a millimeter wave sensor. The millimeter wave sensor is capable of transmitting an electric wave signal of millimeter waves, and receiving a reflection signal that is reflected at an object in the surroundings, and based on the transmitted electric wave signal and the received reflection signal, detects at least any one of the distance from the millimeter wave sensor to an object, the direction in which the object is located with respect to the millimeter wave sensor, and the relative speed of the object with respect to the millimeter wave sensor in a time series. That is, the millimeter wave sensor is capable of detecting the position of an object in the surroundings. The millimeter wave sensor transmits an electric wave signal over a prescribed angular range, and in addition, receives a reflection signal from an object located within a prescribed distance from the millimeter wave sensor. Thus, the detection range of the millimeter wave sensor is a range within the above-described prescribed angular range from the millimeter wave sensor over which an electric wave signal is transmitted, and within a distance of the above-described prescribed distance from the millimeter wave sensor. By using a millimeter wave sensor as the non-contact sensor 21 in this way, it is possible to detect the position and speed of an object, particularly a user, in a non-contact manner with a fast response speed and high accuracy. In addition, it is possible to calculate the motion of an object based on the position and speed of the object detected in a time series.

[0102] Further, as long as the distance of the object, the direction in which the object is present, and the speed of the object can be detected in a non-contact manner, a sensor other than the millimeter wave sensor, such as an infrared sensor, an ultrasonic sensor, or a microwave sensor, can be used as the non-contact sensor 21. In addition, as long as the object in the detection range can be detected in a non-contact manner, a sensor other than the non-contact sensor 21, such as a temperature sensor, can be used as the detection unit. Further, a sensor that can detect the movement of the object in the detection range can be used as the detection unit instead of the non-contact sensor 21.

[0103] The operation sensor 22 is an example of an operation detection unit that detects the operation of the operation unit 20 by the user. In the present embodiment, when the operation unit 20 is pressed by the user, the operation sensor 22 outputs an output signal indicating that the operation unit 20 is pressed. In addition, when the operation unit 20 is rotated by the user, the operation sensor 22 outputs an output signal indicating the angle by which the operation unit 20 is rotated. The output signal from the operation sensor 22 is input to the control unit 30.

[0104] Further, as the operation sensor 22, a sensor corresponding to the type of the operation unit 20 is used. For example, when a button is used as the operation unit 20, as the operation sensor 22, a sensor that outputs a signal that changes depending on whether the button is pressed is used. In addition, when a touch panel is used as the operation unit 20, as the operation sensor 22, a sensor that outputs an output signal indicating the position at which a finger is in contact is used.

[0105] Structure and operation of the control unit

[0106] Next, the structure and operation of the control unit 30 will be described with reference to Figure 3 and Figure 4 The control unit 30 sends a control signal to the display 11, the speaker 12, and the like in accordance with the computer program being executed, based on the signals received from the non-contact sensor 21 and the operation sensor 22. The control unit 30 has a communication interface 31, a memory 32, and a processor 33. Further, the communication interface 31, the memory 32, and the processor 33 can be independent circuits or can be configured as one integrated circuit.

[0107] The control unit 30 controls the sound output by the speaker 12. In the present embodiment, the control unit 30 plays different types of sound, such as the action guide sound, the background sound, the action sound, and the out-of-bed sound, and causes these sounds to be output from the speaker 12. In particular, in the present embodiment, the control unit 30 plays the action guide sound, the background sound, the action sound, and the out-of-bed sound at different timings and for different periods based on the detection result of the non-contact sensor 21 and the like, to promote the user who is sleeping to wake up.

[0108] The action guide sound is an example of the first sound played at the time determined in accordance with the set alarm time when the time of the timer reaches the time. The action guide sound is, for example, an effect sound (including a voice message). The action guide sound is, for example, a sound of a character walking or running in an arbitrary game. Further, the action guide sound can also be music.

[0109] The action guide sound can also be stopped if it is determined that the movement of the object of a size equal to or greater than a certain size is continuously performed during the play, and can be played again after a predetermined snooze time elapses after the action guide sound is stopped.

[0110] The background sound is an example of the fourth sound played without being stopped even if the movement of the object of a certain degree of size is present when the time of the timer reaches the time determined in accordance with the set alarm time. Further, the fourth sound is included in the first sound played at the time determined in accordance with the set alarm time when the time of the timer reaches the time. Thus, the background sound is also an example of the first sound.

[0111] The background sound is played without being stopped even if the movement of the object of a certain degree of size is detected during the play of the background sound, and the background sound is stopped when it is determined that there is a movement of the object moving from the predetermined sleeping area to the outside of the sleeping area. The background sound is a sound different from the action guide sound, the action sound, and the bed exit sound, and is, for example, music. Further, the background sound can also be an effect sound.

[0112] The action sound is an example of the second sound played when it is determined that there is a movement of the object of a certain degree of size based on the detection result of the non-contact sensor 21. That is, the action sound is not played when the user is merely breathing, but is played when the user's body is greatly moved. The action sound is a sound different from the action guide sound, and is, for example, an effect sound (including a voice message). The action sound is, for example, an effect sound played in association with the action of a character in an arbitrary game. Specifically, the action sound is, for example, an effect sound played when a character jumps in an arbitrary game, an effect sound played when a character operates a prop, an effect sound played when an enemy character is attacked, or an effect sound played when a character obtains a prop.

[0113] Further, the action sound can also be music. In particular, in a case where both the action guide sound and the action sound are music, the action sound is music different from the music of the action guide sound. In this case, the action sound is, for example, music associated with the music of the action guide sound and different from the music of the action guide sound. Specifically, for example, the music of the action guide sound is a musical piece without a song, and the action sound is music of the same musical piece as the action guide sound with a song added.

[0114] The bed exit sound is an example of a third sound played when an object that has been detected in the prescribed sleep area based on the detection result of the non-contact sensor 21 is no longer detected in the prescribed sleep area and is detected outside the prescribed sleep area, or when it is determined that there is a movement of such an object from inside the prescribed sleep area to outside the prescribed sleep area. For example, the bed exit sound is played when the user exits the bed. The bed exit sound is a sound different from the action guidance sound and the action sound, and is, for example, an effect sound. In particular, the bed exit sound is an effect sound (including a voice message) such as that played when an event is achieved. The bed exit sound is, for example, an effect sound such as that played when an arbitrary stage is cleared in an arbitrary game. Specifically, the bed exit sound is, for example, a horn sound. Furthermore, the bed exit sound can also be music.

[0115] The communication interface 31 is a circuit for connecting the control section 30 with other electronic components in the main body 10, namely, the display 11, the speaker 12, the non-contact sensor 21, and the operation sensor 22.

[0116] The memory 32 is an example of a storage section that stores data. The memory 32 is a storage medium that stores data, such as a volatile semiconductor memory or a non-volatile semiconductor memory. In addition to this, the memory 32 can also have a removable medium such as a memory card, an optical disc, or the like. The memory 32 stores a computer program that can be executed by the processor 33. In addition, the memory 32 stores various data used by the program being executed, such as the output signal of the non-contact sensor 21 or the like.

[0117] Furthermore, the memory 32 stores data of sounds that can be played by the control section 30. In particular, the memory 32 stores data of the action guidance sound, the action sound, the bed exit sound, and the background sound described above. Thus, the processor 33 acquires the data of the sound to be played from the memory 32, and plays the sound based on the acquired data, whereby the sound is output from the speaker 12.

[0118] In addition, in the present embodiment, the memory 32 stores a plurality of setting items, a plurality of different action guidance sounds, a plurality of different action sounds, a plurality of different bed exit sounds, and a plurality of different background sounds. In addition, the memory 32 stores these sounds and images and the like displayed in the display in association with each setting item. Thus, each setting item is associated with an action guidance sound different from that of another setting item, an action sound different from that of another setting item, a bed exit sound different from that of another setting item, and a background sound different from that of another setting item.

[0119] Specifically, for example, a plurality of setting items correspond to a plurality of different games, and sounds and images associated with each game are stored in the memory 32 in association with the setting items. For example, for a certain setting item, the sound of footsteps of a character of a game corresponding to the setting item is associated as an action guide sound, the action sound of a jump or the like of the character of the game is associated as an action sound, the effect sound at the time of clearing the game is associated as a bed leaving sound, and the BGM of the game is associated as a background sound. In addition, for a setting item corresponding to a certain game, an image of a character of the game or an image of a prop used in the game is associated. Furthermore, it is also possible that a plurality of setting items correspond to one game. In this case, the same sound can be partially included in a plurality of different setting items corresponding to the same game.

[0120] In addition, the memory 32 can not store the setting items. In this case, the memory 32 stores a plurality of different action guide sounds, a plurality of different action sounds, a plurality of different bed leaving sounds, and a plurality of different background sounds regardless of the setting items. Alternatively, the memory 32 can store one action guide sound, one action sound, one bed leaving sound, and one background sound.

[0121] In addition to the above, in the present embodiment, the memory 32 stores various settings made by the user. For example, the memory 32 stores a buzzer time set by the user. In addition, the memory 32 stores the setting item selected by the user from among the setting items stored in the memory 32.

[0122] The processor 33 has one or a plurality of CPUs (Central Processing Unit) and peripheral circuits thereof. The processor 33 can also have other arithmetic circuits such as a logic arithmetic unit or a numerical arithmetic unit. The processor 33 performs various processes based on a computer program stored in the memory 32. For example, the processor 33 performs control processing of the display 11 and the speaker 12, and outputs a control signal to the display 11 and the speaker 12. Thus, the processor 33 controls the image displayed in the display 11 and plays the sound.

[0123] Figure 3 is a functional block diagram of the processor 33 of the control section 30. As Figure 3 indicated, the processor 33 has a timing section 331, a calculation section 332, a determination section 333, a sound play section 334, a count section 335, and a setting section 336. These sections possessed by the processor 33 are functional modules realized by, for example, a computer program acting on the processor 33. Alternatively, each section possessed by the processor 33 can be installed in the control section 30 as an independent integrated circuit, a microprocessor, or firmware.

[0124] The time measuring section 331 measures the time. The time measuring section 331, for example, counts a signal output from a circuit that oscillates at a prescribed period and gradually adds an initial time, thereby measuring the time. The time measured by the time measuring section 331 basically indicates the current time. The time measuring section 331, for example, can also have a function of correcting the time being measured, based on a standard wave indicating a standard time received by a receiver (not shown). The time measured is displayed on the display 11.

[0125] The calculating section 332 calculates the magnitude of the motion of the object within the detection range of the non-contact sensor 21, based on the detection result of the non-contact sensor 21. The calculating section 332 can also calculate the magnitude of the motion of the object within a motion detection area (second area) smaller than (or the same area as) the detection range of the non-contact sensor 21. The calculating section 332 is input with the output signal of the non-contact sensor 21, and the calculating section 332 inputs the detection result to the determining section 333.

[0126] The calculating section 332, for example, calculates the magnitude of the motion of the object based on the change in the distance to the object within the detection range, the change in the direction in which the object is located, and the speed of the object. In the present embodiment, the non-contact sensor 21 is a millimeter wave sensor. Thus, the calculating section 332 calculates the magnitude of the motion of the object, based on the detection result of the distance from the millimeter wave sensor to the object within the detection range detected based on the electric wave signal and the reflected signal, in time series. Alternatively, the calculating section 332 calculates the magnitude of the motion of the object, based on the detection result of the direction in which the object is located with respect to the millimeter wave sensor detected based on the electric wave signal and the reflected signal, in time series. Alternatively, the calculating section 332 calculates the magnitude of the motion of the object, based on the relative speed of the object with respect to the millimeter wave sensor detected based on the electric wave signal and the reflected signal.

[0127] The determining section 333 determines whether or not an arbitrary condition is satisfied, based on the detection result of the non-contact sensor 21. The determining section 333 is input with the output signal of the non-contact sensor 21, and the determining section 333 inputs the determination result to the sound playing section 334.

[0128] The determination section 333 determines whether or not a prescribed motion condition is satisfied on the basis of the detection result of the non-contact sensor 21. The motion condition is a condition that is satisfied in a case where the size of the movement of the object within the motion detection region calculated by the calculation section 332 is a prescribed size or more. The prescribed size is, for example, the size of the movement of the object calculated by the calculation section 332 in a case where the user performs a movement of a size of a prescribed size or more (for example, getting up, turning over, moving the hands and feet, and the like). The prescribed size is, for example, larger than the size of the movement of the object calculated by the calculation section 332 in a case where there is movement of the chest due to the user's breathing. Thus, the motion condition is not satisfied due to the movement of the chest due to the user's breathing during the period in which the user is quietly in bed.

[0129] Figure 4 is a view schematically showing the detection range of the non-contact sensor 21 when the sound playback device 1 is disposed at the side of the bed B on which the user sleeps. In Figure 4 the example shown, the sound playback device 1 is disposed at the side of the bed B with the front surface thereof facing the bed B. As shown in Figure 4 , the detection range of the non-contact sensor 21 reaches a certain angular range (the range shown in gray in the drawing). In addition, the non-contact sensor 21 can detect a distance up to a distance that is sufficiently beyond the size of the bed B (the range shown in gray in the drawing). Thus, the non-contact sensor 21 can detect the movement of an object up to a distance beyond the bed B within the angular range. Further, in a smaller range within the angular range of the detection range shown in Figure 4 , the position of the object can be more accurately detected in a range that is smaller than a prescribed angular range than in a range that is larger than the prescribed angular range. As such, the range in which the position of the object can be more accurately detected can be set as the angular range (the detection range) in which the non-contact sensor 21 performs detection. In addition, with respect to a region within a prescribed lower limit distance (for example, 15 cm) from the non-contact sensor 21, an invalid region in which detection of the object is not performed can also be set.

[0130] In the present embodiment, the region in which the bed B is disposed, that is, the region in which the user is disposed during sleep, is set in advance by the setting section 336. Also, the determination section 333 determines that the motion condition is satisfied in a case where it is determined on the basis of the detection result of the non-contact sensor 21 that there is movement of a prescribed size or more within the detection range and the region in which the bed B is disposed (hereinafter referred to as the "motion detection region"). Thus, even if the object moves outside the motion detection region, the motion condition is not satisfied, and it is possible to avoid determining that the motion condition is satisfied due to movement other than the user on the bed B.

[0131] Furthermore, the motion detection area can be any area within the detection range, or it can be an area outside the area where bed B is located. For example, the motion detection area can also be an area within the detection range and within the upper limit distance (e.g., 3.5m) specified by the sound playback device 1 (i.e., the distance from the non-contact sensor 21), or an area within the detection range and within the sleeping area A described later, etc.

[0132] Alternatively, the motion detection area may also be an area that does not include the area within a specified lower limit distance (e.g., 15 cm) from the sound playback device 1 (i.e., the non-contact sensor 21). For example, even if the user slightly waves their hand, if the hand is close to the non-contact sensor 21, it may be considered that there is a large movement of the user and the motion condition is met. However, this possibility can be reduced by making the motion detection area exclude the area within the lower limit distance.

[0133] Furthermore, the determination unit 333 determines whether the prescribed detachment condition has been met based on the detection result of the non-contact sensor 21. The detachment condition is a condition that is met when it is determined that there is movement of an object moving from inside the pre-set sleeping area (first area) A to outside the sleeping area A. In this embodiment, the setting unit 336 pre-sets the user's sleeping area as a prescribed sleeping area (area A in the figure). The sleeping area A is set to be larger than the actual bed B, so that even if a part of the user (fingers, toes, etc.) slightly protrudes outside the bed B during sleep, it will not be determined that the detachment condition has been met.

[0134] Here, as Figure 4 As shown, consider the scenario where the user moves from inside bed B to outside bed B within the detection range of the non-contact sensor 21, i.e., the user moves towards... Figure 4 The situation is indicated by the white arrow. In this case, after the non-contact sensor 21 detects a large movement of an object indicating that the user has performed an action within the pre-defined sleeping area A, the movement is then detected outside the sleeping area A. Therefore, if the output signal of the non-contact sensor 21 indicates that a movement of an object of the aforementioned predetermined size or greater occurred within the sleeping area A, and then that movement occurred outside the sleeping area A, the determination unit 333 determines that the detachment condition has been met.

[0135] On the other hand, such as Figure 4 As shown, consider the case where the user moves from within the angular range of the non-contact sensor 21 to outside the angular range, i.e., the user moves towards... Figure 4In the case where the user has moved in the direction indicated by the shaded arrow, the non-contact sensor 21 cannot detect the movement of the object outside the sleeping area A. Here, even when the user moves from within the detection range of the non-contact sensor 21 to outside the detection range while still on the bed B, the non-contact sensor 21 may detect small movements such as bed movement caused by the user's breathing. On the other hand, if the user moves from within the detection range of the non-contact sensor 21 to outside the detection range and then moves to outside the bed B, the non-contact sensor 21 will no longer detect even small movements after the user's movement. Therefore, in this embodiment, if the output signal of the non-contact sensor 21 indicates that a movement of an object greater than or equal to the aforementioned predetermined size has occurred within the sleeping area A, and for a predetermined reference time there is no movement of an object less than the aforementioned predetermined size within the sleeping area A, the determination unit 333 determines that the evacuation condition has been met.

[0136] In addition, the sleeping area (first area) may also include... Figure 4 In addition to area A, it also includes areas within the detection range and Figure 4 The area between region A and sound playback device 1 (i.e., Figure 5-8 (The area between region A and the non-contact sensor 21). Therefore, it is possible to suppress the determination that the detachment condition has been met when the user reaches out to operate the sound playback device 1. Additionally, the determination unit 333 can also determine that the user is in bed based on the movement of an object in a predetermined area within the bed B, which is smaller than the bed B.

[0137] The sound playback unit 334 plays sound, and simultaneously, the sound is output from the speaker 12. When predetermined conditions are met, the sound playback unit 334 performs actions such as playing action guidance sounds, playing action sounds, playing bed-leaving sounds, or playing background sounds. Furthermore, when predetermined conditions are met, the sound playback unit 334 stops playing action guidance sounds, action sounds, bed-leaving sounds, or background sounds. Details of the sound playback control performed by the sound playback unit 334 will be described later.

[0138] The counting unit 335 counts the time during which the determination unit 333 determines that the action condition is met, and uses this count as the action time. Specifically, during the playback of the action guidance sound, the counting unit 335 counts the time during which the determination unit 333 determines that the action condition is met, and uses this count as the action time. Therefore, the action time represents the time during the playback of the action guidance sound when the action condition is met. Furthermore, after the counting unit 335 starts counting the action time when the action condition is met, it also stops counting the action time during the period when the action condition is not met.

[0139] The setting section 336 performs setting necessary for the operation of the sound playback device 1 such as the playback of sound. In the present embodiment, the setting section 336 performs setting of various items based on input by the user via the operation section 20. The setting section 336, for example, performs setting of the alarm time that is the time at which the alarm should be started, the sleep area A, and the area in which the bed B is located. The area in which the sleep area A and the bed B are located is set, for example, by inputting the configuration position of the sound playback device with respect to the bed, the distance between the sound playback device 1 and the bed B, and the size of the bed B by the user via the operation section 20. In addition, the setting section 336 performs setting of the setting item selected by the user from among the plurality of setting items stored in the memory 32. The setting section 336, for example, performs setting of these items based on the output signal from the operation section 20 operated by the user. The items set by the setting section 336, such as the alarm time set by the user via the setting section 336, the sound-related setting item, the sleep area A, and the area in which the bed B is located, are stored in the memory 32.

[0140] In addition, when the setting item selected by the user is set by the setting section 336, the sound playback section 334 plays sound in the sound playback process in accordance with the set setting item. The sound playback section 334 plays the action guide sound associated with the setting item selected by the user during the execution of the action guide sound playback process, and plays the action sound associated with the setting item selected by the user during the execution of the action sound playback process. In addition to this, the sound playback section 334 plays the get-out-of-bed sound associated with the setting item selected by the user during the execution of the get-out-of-bed sound playback process, and plays the background sound associated with the setting item selected by the user during the execution of the background sound playback process. Thus, the sound playback section 334 plays sound based on the selection of the user from among a plurality of different sounds. By this, it is possible to play sound that conforms to the user's preferences.

[0141] In addition, the setting section 336 can not set the setting item related to the sound, but set a sound selected by the user from among a plurality of different sounds stored in the storage 32. In this case, for example, the setting section 336 sets one of the plurality of action guide sounds selected by the user as the action guide sound played in the action guide sound playback process. Similarly, the setting section 336 sets one of the plurality of action sounds, one of the plurality of get-out-of-bed sounds, and one of the plurality of background sounds selected by the user as the action sound played in the action sound playback process, the get-out-of-bed sound played in the get-out-of-bed sound playback process, and the background sound played in the background sound playback process, respectively. As a result, the sound playback section 334 plays the action guide sound selected by the user during the execution of the action guide sound playback process, and plays the action sound selected by the user during the execution of the action sound playback process. In addition to this, the sound playback section 334 also plays the get-out-of-bed sound selected by the user during the execution of the get-out-of-bed sound playback process, and plays the background sound selected by the user during the execution of the background sound playback process. By playing the sound based on the selection of the user like this, it is possible to play a sound that follows the preference of the user.

[0142] Further, the setting by the setting section 336 can not necessarily be made based on the output signal from the operation section 20. For example, it can be configured such that, when the sound playback device 1 is set to the bed area detection mode, the setting section 336 sets the area in which the movement of the object is detected by the non-contact sensor 21 (for example, the area in which the movement is detected by the user intentionally moving on the bed) as the area in which the sleep area A and the bed B are located.

[0143] Playback control of sound

[0144] Next, the playback control of the sound in the sound playback device 1 configured as such will be described with reference to Figure 5 Figure 6 is a time chart of the volume of the entire sound output by the sound playback device 1, the sufficiency of the action condition, the action time, and the sufficiency of the escape condition. Figure 5 is a time chart of the volume of each sound in Figure 5 Figure 6 and Figure 5 The horizontal axis in

[0145] In the example shown in Figure 6 and Figure 5 The alarm time is set to the time t0. Thus, before the time t0, the sound playback section 334 stops the playback of all the sounds of the action guide sound, the action sound, the get-out-of-bed sound, and the background sound.

[0146] ​​In the present embodiment, the sound playback section 334 starts the background sound playback process when the timekeeping time reaches the time determined in accordance with the alarm time. In addition to this, the sound playback section 334 also starts the action guide sound playback process when the timekeeping time reaches the time determined in accordance with the alarm time. The time determined in accordance with the alarm time can be the alarm time, a time that is a predetermined time before the alarm time, or a time that is a predetermined time after the alarm time. Thus, the user can be notified that the timekeeping time has reached the alarm time. In addition, the background sound playback process and the action guide sound playback process can start at the same time or at different times.

[0147] In Figure 6 and Figure 5 In the example shown in FIG. 10, the sound playback section 334 starts to execute the background sound playback process that plays the background sound at the time to that is the alarm time, and then gradually increases the volume. In the present embodiment, when the time tl that is a certain time after the time to is reached, the sound playback section 334 temporarily stops increasing the volume of the background sound until the time t2. The time to to the time t2 is the prelude period, and the volume of the sound of the sound playback device 1 is suppressed to the low first volume vl. Thus, the user who is sleeping can be prevented from being startled by suddenly outputting a large volume of sound. In addition, the prelude period is not necessarily necessary.

[0148] When the prelude period is completed at the time t2, the sound playback section 334 then starts to execute the action guide sound playback process that plays the action guide sound, and gradually increases the volume of the action guide sound. Thus, in the present embodiment, the playing of the action guide sound starts after a predetermined prelude period has elapsed from the alarm time. That is, it can be said that the playback process that plays the action guide sound is executed when the timekeeping time becomes the time determined in accordance with the alarm time. In addition, as described above, the prelude period is not necessarily necessary, and thus the action guide sound playback process can start at the time to that is the alarm time. In addition to this, the sound playback section 334 also increases the volume of the background sound after the time t2. In addition, in the present embodiment, the volume of the action guide sound is a volume that is larger than the volume of the background sound.

[0149] In the present embodiment, when the time t3, which is a certain time after the time t2, is reached, the sound playing section 334 thereafter maintains the volume of the background sound at a constant fourth volume v4. Thereafter, when the time t4, which is a certain time after the time t2, is reached, the sound playing section 334 thereafter maintains the volume of the action guide sound at a constant fifth volume v5. In the present embodiment, the fifth volume v5 is a volume larger than the fourth volume v4. Further, in the present embodiment, the timing at which the background sound reaches the fourth volume v4 (the time t3) is different from the timing at which the action guide sound reaches the fifth volume v5 (the time t4), but the timings can be the same.

[0150] Further, during the execution of the action guide sound playing process or during the execution of the background sound playing process, an arbitrary image can also be displayed on the display 11. For example, in the case where the action guide sound is the footsteps of a certain character, an image in which the character is walking or running can be displayed on the display 11 during the playing of the action guide sound.

[0151] When the user starts moving on the bed B due to the playing of the action guide sound, the determination section 333 determines that the action condition is satisfied in accordance with the movement. In the present embodiment, when the determination section 333 determines that the action condition is satisfied during the playing of the action guide sound, the sound playing section 334 starts the execution of the action sound playing process that plays the action sound. Thus, in the example shown in FIG. 10, the action sound playing process is started at the time t5. The volume of the action sound is smaller than the fifth volume v5. As such, the action sound is played when the determination section 333 determines that the action condition is satisfied, whereby the user can be prompted to move the body. As a result, the user in sleep can be prompted to wake up. Further, by making the volume of the action sound smaller than the fifth volume v5, the user moves the body in order to reduce the sound output by the sound playing apparatus 1, whereby the user can be prompted to wake up. Figure 6 and Figure 5 In the example shown in FIG. 10, the action sound playing process is started at the time t5. The volume of the action sound is smaller than the fifth volume v5. As such, the action sound is played when the determination section 333 determines that the action condition is satisfied, whereby the user can be prompted to move the body. As a result, the user in sleep can be prompted to wake up. Further, by making the volume of the action sound smaller than the fifth volume v5, the user moves the body in order to reduce the sound output by the sound playing apparatus 1, whereby the user can be prompted to wake up.

[0152] Further, during the execution of the action sound playing process, an arbitrary image can also be displayed on the display 11 in conjunction with the playing of the action sound. For example, in the case where the action sound is an effect sound that is obtained when a prop is acquired, an image of the prop can be displayed on the display 11.

[0153] In addition, in this embodiment, the sound playback unit 334 also reduces the volume of the action guide sound and the background sound to a third volume v3 and a second volume v2, respectively, while performing the action sound playback processing. In this embodiment, the third volume v3 is a volume lower than the fourth volume v4, but only needs to be lower than the fifth volume v5, and can also be a volume higher than the fourth volume v4. Furthermore, in this embodiment, the second volume v2 is a volume lower than the third volume v3 and higher than the first volume v1. By reducing the volume of the action guide sound and the background sound in this way, the user can easily hear the action sound. In addition, during the execution of the action sound playback processing, the volume of at least one of the action guide sound and the background sound can be set to zero.

[0154] The action sound playback processing is executed during the period when the determination unit 333 determines that the action condition is met during the execution of the action guidance sound playback processing or the background sound playback processing. Specifically, in this embodiment, the action sound playback processing is executed during the period when the action time counted by the counting unit 335 is not zero. Figure 6 and Figure 5 In the example shown, after time t5, the user moves significantly on bed B. Therefore, after time t5, the counting unit 335 continues to count the movement time. Thus, in Figure 6 and Figure 5 In the example shown, the sound playback unit 334 continues to perform action sound playback processing after time t5.

[0155] In addition, such as Figure 6 and Figure 5 As shown, during the execution of the action sound playback process, the counting unit 335 counts the time during which the determination unit 333 determines that the action conditions are met, and uses this count as the action time. Furthermore, in this embodiment, when the action time counted by the counting unit 335 reaches a predetermined sound stop time Ts (a first time; for example, 1 second or more, 2 seconds or more, or 2.5 seconds or more, or 10 seconds or less, 5 seconds or less, or 3 seconds or less) (time t6), the sound playback unit 334 stops the action sound playback process. That is, when the determination unit 333 determines that the total time during which the action conditions are met reaches the sound stop time Ts, the sound playback unit 334 stops the action sound playback process.

[0156] In the present embodiment, when the stop condition that the action time counted by the counting section 335 reaches the sound stop time Ts is satisfied, the sound playing section 334 stops the action guide sound playing process, and thus the playing of the action guide sound is stopped. That is, during the playing of the action guide sound, the action guide sound is stopped because the user continues to move for a certain period of time. Thus, when the action guide sound is played, the user moves the body in order to stop the playing of the action guide sound, and thus the user can be prompted to wake up. When the action guide sound is stopped, thereafter, the action guide sound playing process is not executed again for the nap time Tn described later. Also, in the present embodiment, when the action time counted by the counting section 335 reaches the sound stop time Ts, the sound playing section 334 reduces the volume of the background sound to the first volume. Thus, by the user moving the body, the volume of the background sound is also reduced, and thus the user moves the body more actively, and thus the user can be prompted to wake up. Further, when the action time counted by the counting section 335 reaches the sound stop time Ts, the volume of the background sound can also be reduced to a volume different from the first volume, or can not be reduced.

[0157] Further, in the present embodiment, when the action time counted by the counting section 335 reaches the sound stop time Ts, the sound playing section 334 stops the action guide sound playing process and the action sound playing process. However, the sound playing section 334 can also stop the action guide sound playing process and the action sound playing process, for example, when the action duration value calculated by dividing the action time (action duration) counted by the counting section 335 by the maximum action duration corresponding to the sound stop time Ts described above reaches 100%. That is, it can be said that the sound playing section 334 stops the action guide sound playing process and the action sound playing process in a case where the stop condition that the action time counted by the counting section 335 reaches the prescribed sound stop time Ts is satisfied.

[0158] Further, it can also be that, when the stop condition is satisfied, the sound playing section 334 stops only the action guide sound playing process, and continues to execute the action sound playing process as long as the action condition is determined to be satisfied by the determination section 333. Or, it can also be that, when the stop condition is satisfied, the sound playing section 334 does not stop the action guide sound playing process, but stops only the action sound playing process. In this case, the volume of the action guide sound can also be reduced when the stop condition is satisfied.

[0159] In the present embodiment, during the execution of the action sound playing process, as described above, the sound playing section 334 plays the action guide sound and the action sound. Thus, the user can be prompted to wake up by the action guide sound and the action sound. Figure 6 and Figure 5As shown, the action sound is played intermittently. Thus, during the execution of the action sound play process, the action sound is played multiple times. In other words, in the present embodiment, during the execution of the action sound play process, the action sound is played intermittently multiple times from the start of the action sound play process until the action guide sound play process is stopped due to the satisfaction of the stop condition. In the example shown, the action sound is played eight times during the execution of the action sound play process. Figure 6 and Figure 7 In the example shown, the action sound is played eight times during the execution of the action sound play process.

[0160] In addition, in the present embodiment, during the execution of the action sound play process, the sound play section 334 also plays the action sound in such a manner that the time (hereinafter referred to as "action determination time between sounds") during which the action condition is determined to be satisfied by the determination section 333 between one action sound and the next played action sound varies depending on the number of times the action sound has been played in one action sound play process. For example, the sound play section 334 plays the action sound in such a manner that the action determination time between sounds increases as the number of times the action sound has been played increases. The sound play section 334 can also play the action sound in such a manner that the action determination time between sounds increases as the action time counted by the counting section 335 increases. Thus, for example, the action determination time between the play of the action sound for the first time after the start of the action sound play process and the play of the action sound for the second time is shorter than the action determination time between the play of the action sound for the second time and the play of the action sound for the third time. Here, if the action determination time between sounds is long from the start of the action sound play process, the user can lose motivation to move the body because the action sound can be difficult to play, but in the present embodiment, by making the action determination time between sounds short at the early stage of the start of the action sound play process, the user does not lose motivation to move the body. In addition, the user who has moved the body for a certain period of time moves the body with the goal of hearing the next action sound, and thus, by increasing the action determination time as time elapses from the start of the action sound play process, the user can be made to be more alert.

[0161] Also, in the present embodiment, the multiple action sounds played during the execution of the action sound play process are at least partially different sounds. For example, the action sounds are at least partially different effect sounds. Thus, multiple different sound tracks played as action sounds corresponding to one setting item are stored in the storage 32, and the multiple different sound tracks are played during the execution of the action sound play process. The different sounds are, for example, different effect sounds (for example, an effect sound played when a character jumps in an arbitrary game, an effect sound played when the character operates a prop, an effect sound played when the character obtains a prop, etc.). In addition, the different sounds can also be effect sounds that are the same as each other but different in pitch and speed.

[0162] In the present embodiment, the plurality of different action sounds played during the execution of the action sound play process are changed based on the action time counted by the counting section 335. Thus, for example, the action sounds during a period in which the action time is relatively short (the play of the first action sound to the fourth action sound) are set to an effect sound played when a character jumps in an arbitrary game, and the action sounds during a period in which the action time is relatively long (the play of the fifth action sound to the eighth action sound) are set to an effect sound played when the character acquires a tool in the arbitrary game. Thereby, the user can recognize the action time counted by the counting section 335, and can intuitively grasp the time for which the action should be continued until the action guide sound and the like is stopped. In addition, the action sounds to be played can also be determined in advance according to the order of the action sound play.

[0163] In addition, the action sound played when the action time reaches the sound stop time Ts (the last action sound played during the execution of the action sound play process) can also be set to an effect sound different from the other action sounds, such as an effect sound played when an enemy is defeated in an arbitrary game. Thereby, the user can recognize that the action time reaches the sound stop time Ts, and that the action guide sound play process and the action sound play process end.

[0164] Further, the plurality of different action sounds played during the execution of the action sound play process can also be changed based on the remaining time until the time at which the action condition is satisfied reaches the sound stop time Ts. Alternatively, the plurality of different action sounds played during the execution of the action sound play process can all be the same sound.

[0165] Next, the control of the play of the action sound in a case in which there is a period in which the user does not move greatly on the bed B during the execution of the action sound play process will be described with reference to Figure 7 . Figure 7 is a time chart of the volume of the action guide sound and the action sound during the execution of the action sound play process, the action condition, and the action time counted by the counting section 335.

[0166] As shown in Figure 7 , when it is determined by the determination section 333 that the action condition is satisfied at time t5, the counting of the action time by the counting section 335 is started. In the example shown in Figure 7 , from time t5 to time t 5a , the user moves greatly on the bed B, and thus, from time t5 to time t 5a , it is determined that the action condition is satisfied. Thus, from time t5 to time t 5aDuring the period until the time t

[0167] In Figure 7 the example shown, after the time t 5a , the user stops moving, as a result of which, after the time t 5a , the determination unit 333 determines that the movement condition is not satisfied. The counting unit 335 counts the time during which the determination unit 333 determines that the movement condition is satisfied as the movement time, and therefore, after the time t 5a , the movement time counted by the counting unit 335 does not increase and remains constant. After the time t 5a , the movement time counted by the counting unit 335 is also not zero, and therefore, the action sound playback processing continues.

[0168] Further, in the present embodiment, after the counting of the movement time by the counting unit 335 is started, when the time during which the determination unit 333 continuously determines that the movement condition is not satisfied, i.e., the non-movement time, reaches a predetermined reset time (fourth time) Tr, the counting unit 335 resets the movement time to zero. The reset time Tr is a time shorter than the sound stop time Ts, and for example, is 0.5 seconds or more, 0.7 seconds or more, or 0.9 seconds or more, and 5 seconds or less, 3 seconds or less, or 2 seconds or less. As a result, the user will continuously move in order to avoid the counting unit 335 returning to zero due to the user continuously resetting the movement time, and thus it is possible to encourage the user to move.

[0169] In Figure 7 the example shown, after the time t 5a , the determination unit 333 continuously determines that the movement condition is not satisfied for a time of the reset time Tr or more. Thus, after the time t 5a from which the determination unit 333 starts determining that the movement condition is not satisfied, the time t 5b , after the reset time Tr elapses, the movement time counted by the counting unit 335 is reset to zero. Alternatively, it is also possible that the counting processing in the counting unit 335 ends at the time t 5b . Thus, at the time t 5b , the action sound playback processing stops.

[0170] In addition, in the present embodiment, when the action time counted by the counting section 335 is reset to zero, the volume of the action guide sound is raised from the third volume v3 to the fifth volume v5. In addition, at this time, the volume of the background sound is raised from the second volume v2 to the fourth volume v4. That is, when the action time counted by the counting section 335 is reset to zero, the state before the start of the action sound playback processing is returned to. Further, when the action time counted by the counting section 335 is reset to zero, the volume of the action guide sound and the volume of the background sound can also not be raised. In this case, when the time during which the action condition is determined not to be satisfied by the determination section 333 elapses for a prescribed time longer than the reset time, or when a prescribed time elapses from when the action time counted by the counting section 335 is reset to zero, the volume of the action guide sound and the volume of the background sound are raised.

[0171] Further, in the present embodiment, in the case where the time during which the action condition is determined not to be satisfied reaches the reset time Tr after the start of counting of the action time, the action time counted by the counting section 335 is reset to zero. However, as long as the action time counted by the counting section 335 is changed based on the time during which the action condition is determined not to be satisfied after the start of counting of the action time, it can not necessarily be reset to zero. For example, the longer the time during which the action condition is determined not to be satisfied, the shorter the action time counted by the counting section 335 is set to be. Thereby, when the user stops the action, the time required to stop the action guide sound increases, and thus the action of the user can be promoted. Or, it can be that, after the start of counting of the action time, the action time being counted is not changed even if there is the time during which the action condition is determined not to be satisfied.

[0172] Further, it can be that, after the start of counting of the action time, the action time counted by the counting section 335 is not changed but the sound stop time Ts is changed based on the time during which the action condition is determined not to be satisfied. In this case, for example, the longer the time during which the action condition is determined not to be satisfied after the start of counting of the action time, the longer the sound stop time Ts is set to be. Thereby, when the user stops the action, the time required to stop the action guide sound increases, and thus the action of the user can be promoted.

[0173] In Figure 7 the example shown in FIG. 10, after the determination section 333 determines that the action condition is not satisfied from time t 5a to time t 5c , the user starts the action again at time t 5c , and the determination section 333 determines that the action condition is satisfied. As a result, at time t 5c , the action sound playback processing is started again, and the volumes of the action guide sound and the background sound are lowered, and the counting of the action time by the counting section 335 is started.

[0174] exist Figure 7 In the example shown, afterwards, at time t 5d up to time t 5e During this period, the user stops moving, and the decision unit 333 again determines that the action condition has not been met. However, from time t... 5d At time t 5e The time interval up to this point is shorter than the reset time Tr, resulting in the action time counted by the counter unit 335 not being reset to zero. Furthermore, in Figure 5 In the example shown, at time t 5e Subsequently, the user continues to perform actions, resulting in the action time counted by counter 335 increasing until, at time t6, the action time reaches the sound stop time Ts. When the action time reaches the sound stop time Ts, the stopping condition is satisfied, and... Figure 6 and Figure 5 Similarly, in the example shown, the sound playback unit 334 stops the action guidance sound playback processing and the action sound playback processing.

[0175] Back to Figure 6 and Figure 5 At time t6, the action guide sound playback processing and action sound playback processing stop; therefore, after time t6, background sounds are played at a relatively low initial volume v1. Figure 6 and Figure 5 In the example shown, the user stops the action at a time later than time t6, and therefore, the decision unit 333 determines that the action condition has not been met.

[0176] In this embodiment, after the action guidance sound playback process is stopped due to the stopping condition being met, the sound playback unit 334 restarts the action guidance sound playback process when the restart condition is met. In this embodiment, the restart condition is met when a short nap time (second time) Tn has elapsed since the action guidance sound playback process stopped, and the non-action time determined by the determination unit 333 as not having met the action condition reaches a pause determination time (third time) Tm. The nap time Tn is, for example, 3 minutes or less. It can also be a time longer than 3 minutes, or a time shorter than 3 minutes. The pause determination time Tm is a time shorter than the nap time, for example, 30 seconds. It can also be a time longer than 30 seconds, or a time shorter than 30 seconds.

[0177] exist Figure 6 and Figure 5 In the example shown, at time t7, a nap time Tn has elapsed since time t6, and just before time t7, the decision unit 333 continuously paused the decision time Tm to continuously determine that the action condition was not met. Therefore, in Figure 6 andFigure 5 In the example shown, at time t7, the action guidance sound playback process is restarted.

[0178] As such, in the present embodiment, in the case where the user stops the action on the bed B after having performed the action, the action guidance sound is played again. In the case where the user stops the action on the bed B, the playback of the action guidance sound is repeated.

[0179] Further, the restart condition can also be a condition that is satisfied when only one of the following conditions is satisfied after the action guidance sound playback process is stopped due to the stop condition being satisfied: the nap time Tn has elapsed; and the non-action time in which the action condition is not satisfied is determined by the determination section 333 to have reached the pause determination time Tm. For example, in the case where 10 minutes have elapsed from when the action guidance sound playback process is stopped, the action guidance sound playback process is restarted regardless of whether the action condition is satisfied or not.

[0180] Thereafter, in the present embodiment, at time t7 to time t 11 , the same action as that from time t2 to time t6 is repeated. In the present embodiment, the same operation as that from time t2 to time t6 is repeated until the disengagement condition described above is determined by the determination section 333 to be satisfied.

[0181] Further, when the disengagement condition is determined by the determination section 333 to be satisfied, in the case where the action guidance sound playback process, the action sound playback process, or the background sound playback process is being executed, the sound playback section 334 stops these processes. In addition, when the disengagement condition is determined by the determination section 333 to be satisfied, even if the restart condition is satisfied thereafter, the action guidance sound playback process is not restarted by the sound playback section 334. Thus, when the disengagement condition is determined by the determination section 333 to be satisfied, thereafter, the sound playback section 334 does not execute the action guidance sound playback process, the action sound playback process, and the background sound playback process until the timing time counted by the timing section 331 reaches the time determined in accordance with the alarm time. Thereby, it is possible to completely stop the playback of the sound based on the user having left the bed. In particular, in the present embodiment, the background sound playback process is stopped in the case where the disengagement condition is determined by the determination section 333 to be satisfied, and thus it is possible to urge the user to leave the bed.

[0182] Furthermore, when the determination unit 333 determines that the escaping condition has been met, the sound playback unit 334 performs an escaping sound playback process, playing an escaping sound that differs from the action guidance sound, action sound, and background sound. Moreover, the escaping sound playback process is only executed when the escaping condition is determined to be met. Therefore, for example, even when the stop condition is met or the restart condition is met, the escaping sound playback process is not executed as long as the escaping condition is not met. By playing the escaping sound only when the escaping condition is met, the user can understand that the action guidance sound playback process, etc., has been stopped and will not be executed in the future.

[0183] Additionally, when the determination unit 333 determines that the release condition has been met, the counting unit 335 resets the operation time to zero. Alternatively, when the release condition is determined to be met, the counting process in the counting unit 335 ends.

[0184] exist Figure 6 and Figure 8 In the example shown, at time t 12 The decision unit 333 determines that the escape condition is met. Therefore, at time t... 12 The system executes the step-out sound playback process, playing the step-out sound. In addition, at time t... 12 Background sound playback also stops, thus stopping the playback of background sounds.

[0185] Figure 5 The overall volume of the sound played by the sound playback device 1, etc. Figure 8 The same timing diagram. In Figure 8 In the example shown, at time t 10 After the action sound playback processing begins, before the action time counted by the counting unit 335 reaches the sound stop time Ts, the determination unit 333 determines that the escape condition has been met.

[0186] like Figure 9-11 As shown, when the determination unit 333 determines that the escape condition is met during the execution of the action guidance sound playback processing, action sound playback processing, and background sound playback processing (time t), 13 The sound playback unit 334 stops these processes. Therefore, at time t... 13 The playback of action guidance sounds, action sounds, and background sounds stops. In addition, the sound playback unit 334 stops at time t. 13 The process of playing an exit-from-bed sound is performed, thereby playing an exit-from-bed sound. In addition, in this embodiment, at time t... 13 The action time counted by the counter unit 335 is reset to zero.

[0187] Control process

[0188] Next, refer toFigure 9 The flow of the control will be described. Figure 9 is a flowchart showing the flow of the play processing of playing various sounds from the speaker 12. The illustrated play processing is executed by the processor 33 of the control section 30 when the alarm time is set by the setting section 336.

[0189] As shown in Figure 10 When the play processing is started, first, the sound play section 334 determines whether or not the disengagement condition is determined to be satisfied by the determination section 333 (step Sll). In the case where it is determined in step Sll that the disengagement condition is satisfied, the sound play section 334 stops the background sound control processing which controls the background sound play processing, the action guide sound control processing which controls the action guide sound play processing, and the action sound control processing which controls the action sound play processing. Thus, in the case where the background sound play processing, the action guide sound play processing, or the action sound play processing is being executed, these play processings are stopped. In addition to this, the sound play section 334 also executes the out-of-bed sound play processing, and thus, the out-of-bed sound is played (step S13), and the play processing ends.

[0190] In the case where it is determined in step Sll that the disengagement condition is not satisfied, the sound play section 334 executes the background sound control processing (step S14). During the execution of the background sound control processing, when the alarm time set is reached by the time in the time section 331, the sound play section 334 starts the background sound play processing to play the background sound. In addition, during the execution of the background sound control processing, when the play of the background sound is started, the sound play section 334 causes the volume of the background sound to be raised stepwise in the order of the first volume vl, the fourth volume v4. In addition, when the action time counted by the count section 335 increases from zero, the sound play section 334 causes the volume of the background sound to be lowered to the second volume v2, and when the action time becomes zero, the sound play section 334 causes the volume of the background sound to be raised to the fourth volume v4. Further, when the stop condition that the action time reaches the sound stop time Ts is satisfied, the sound play section 334 causes the volume of the background sound to be lowered to the first volume vl. In addition to this, when the restart condition is satisfied after the stop condition is satisfied, the sound play section 334 causes the volume of the background sound to be raised again to the fourth volume v4.

[0191] Next, the sound playing section 334 executes the action guiding sound control processing (step S15). The sound playing section 334 starts the action guiding sound playing processing to play the action guiding sound when the timing time in the timing section 331 reaches a time after the prelude period from the set alarm time during the execution of the action guiding sound control processing. In addition, the sound playing section 334 increases the volume of the action guiding sound to the fifth volume v5 when the playing of the action guiding sound is started during the execution of the action guiding sound control processing. In addition, the sound playing section 334 decreases the volume of the action guiding sound to the third volume v3 when the action time counted by the counting section 335 increases from zero, and increases the volume of the action guiding sound to the fifth volume v5 when the action time becomes zero. Furthermore, the sound playing section 334 stops the action guiding sound playing processing when the action time reaches the sound stop time Ts, which is a stop condition. In addition, the sound playing section 334 starts the action guiding sound playing processing again and increases the volume of the action guiding sound to the fifth volume v5 again when the restart condition is satisfied after the stop condition is satisfied.

[0192] Next, the sound playing section 334 executes the action sound control processing (step S16). The action sound control processing will be described with reference to Figure 10 Figure 9 is a flowchart showing the flow of the action sound control processing. The illustrated action sound control processing is executed during the playing processing of the action guiding sound in step S16, and is executed until the action sound control processing is stopped in step S12. Figure 10

[0193] As shown in Figure 7 , when the action sound control processing is started, the sound playing section 334 first determines whether or not it is in the executable period of the action sound playing processing (step S21). In the present embodiment, the action sound playing processing is executed during the playing period of the action guiding sound, and thus it is determined that it is in the executable period of the action sound playing processing when the action guiding sound playing processing is being executed.

[0194] ​​If, in step S21, it is determined that the action sound playback process is within an executable period, the sound playback unit 334 determines whether the action condition has been met, as determined by the determination unit 333 (step S22). If, in step S22, the action condition is met, and in step S27 (described later), the counting unit 335 is counting the non-action time, the counting unit 335 resets the non-action time to zero (step S23). Next, the counting unit 335 increments the currently counting action time (step S24). Next, the sound playback unit 334 determines whether the action time counted in step S24 is greater than or equal to a predetermined sound stop time Ts (step S25). If, in step S25, it is determined that the action time is less than the sound stop time Ts, the action sound playback process is executed. The action sound playback process will be described later.

[0195] On the other hand, if it is determined in step S25 that the action time is greater than or equal to the sound stop time Ts, the action time and non-action time counted by the counting unit 335 are both reset to zero (step S27). Then, if the action sound playback processing is in progress, the sound playback unit 334 stops the action sound playback processing (step S28). Furthermore, if it is determined in step S21 that the action sound playback processing is not in an executable period, for example, if the action guidance sound playback processing is not being performed, the action time and non-action time are also reset to zero (step S27), and the action sound playback processing is stopped (step S28).

[0196] If, in step S22, it is determined that the operation condition is not met, the counting unit 335 increases the non-operation time being counted (step S29). Next, the sound playback unit 334 determines whether the non-operation time counted in step S29 is greater than or equal to a predetermined reset time Tr (step S30). If, in step S30, it is determined that the non-operation time is less than the reset time Tr, the sound playback unit 334 determines whether the operation time counted by the counting unit 335 is zero (step S31).

[0197] If, in step S31, it is determined that the action time is not zero, that is, if action sound playback processing has been performed after the determination that it is within the executable period of action sound playback processing, then action sound playback processing is executed (step S26). Figure 11 The moment t 5a ~t 5b Time t 5d ~t 5e). On the other hand, in a case where it is determined in step S31 that the action time is zero, that is, in a case where it is determined that the action sound play processing has not been executed even once after the executable period of the action sound play processing, the action time and the non-action time are both reset to zero (step S27), and the action sound play processing is stopped (step S28).

[0198] Next, the action sound play processing will be described with reference to Figure 11 Figure 10 is a flowchart showing the flow of the action sound play processing. The illustrated action sound play processing is executed during the period in which the action sound control processing of Figure 11 is repeated through step S26.

[0199] As shown in Figure 5 , when the action sound play processing is started, first, the sound play section 334 determines whether the stop of the action sound play processing is requested (step S41). When the action sound play processing is stopped in step S28 of the action sound control processing, the sound play section 334 determines that the stop of the action sound play processing is requested. In a case where it is determined in step S41 that the stop of the action sound play processing is requested, the action sound play processing ends.

[0200] On the other hand, in a case where it is determined in step S41 that the stop of the action sound play processing is not requested, the sound play section 334 determines whether the action time that is counted in step S24 of the action sound control processing is a prescribed sound play timing (step S42). The sound play timing indicates the timing at which each of the action sounds that are played multiple times in the action sound play processing is played. In the present embodiment, the time interval of the play timings of the two action sounds that are played consecutively (that is, the action determination time between sounds) is different from each other. In particular, in the present embodiment, as described above, the time interval of the play timings of the two action sounds that are played consecutively increases as the number of times the action sound has been played increases.

[0201] In a case where it is determined in step S42 that the action time is not the sound play timing, step S41 is repeated. On the other hand, in a case where it is determined in step S42 that the action time is the sound play timing, the count section 335 increases the count of the number of times the action sound is played by one (step S43). Next, the sound play section 334 plays the action sound corresponding to the number of times the action sound is counted in step S43 (step S44), and thereafter, step S41 is repeated.

[0202] Modified Example

[0203] ​In the above-described embodiment, the sound is completely stopped from being played when it is determined by the determination section 333 that the disengagement condition is satisfied. However, the sound can be completely stopped from being played for a reason other than the disengagement condition being satisfied. For example, the sound can be completely stopped from being played in accordance with the operation section 20 being pressed by the user, a certain time (for example, 1 hour) elapsing from the timing moment to the moment determined in accordance with the alarm timing moment.

[0204] In addition, in the above-described embodiment, the sound playing section 334 plays the action guide sound while superimposing it on the background sound. However, it can be configured so that the sound playing section 334 stops the playing of the background sound while playing the action guide sound. In this case, the sound playing section 334 stops the background sound playing process while executing the action guide sound playing process. Also, the sound playing section 334 restarts the background sound playing process when the action guide sound playing process is stopped, except when it is determined that the disengagement condition is satisfied. Thus, in the example shown in FIG. 17, the background sound is stopped from being played at the timing t2 to t6 and the timing t7 to t Figure 6 and ​ In the example shown in FIG. 17, the background sound is stopped from being played at the timing t2 to t6 and the timing t7 to t 11 , the playing of the background sound can also be stopped.

[0205] In addition, in the above-described embodiment, the sound playing section 334 plays the action sound while superimposing it on the action guide sound and the background sound. However, in one modification, it can be configured so that the sound playing section 334 stops the playing of the action guide sound and the background sound during the playing of the action sound. In this case, it can be configured so that the action sound and the action guide sound are both music, and as described above, the action sound is music that is associated with the music of the action guide sound and is different from the music of the action guide sound.

[0206] Specifically, in this modification, the sound playing section 334 stops the action guide sound playing process and the background sound playing process while executing the action sound playing process. Also, the sound playing section 334 restarts the action guide sound playing process and the background sound playing process when the action sound playing process is stopped for a reason other than the stop condition being satisfied. Alternatively, the sound playing section 334 can stop the action guide sound playing process and the background sound playing process while playing the action sound (i.e., while playing each of the action sounds that are played multiple times in the action sound playing process). Also, the sound playing section 334 can restart the action guide sound playing process and the background sound playing process when the playing of the action sound is stopped for a reason other than the stop condition being satisfied.

[0207] In addition, either one of the action guidance sound play processing and the background sound play processing can not be executed. Thus, in this case, only either one of the action guidance sound play processing and the background sound play processing is executed when the timing time reaches the time determined in accordance with the alarm time.

[0208] In addition, in the above embodiment, when the action sound play processing is stopped due to the action condition being determined to be satisfied by the determination section 333, the action sound play processing is not executed for the doze time Tn. However, in one modification, the action sound play processing can be executed before the doze time Tn elapses. That is, the action sound play processing can be executed when the action guidance sound play processing is not executed.

[0209] In addition, in the case where the sound play section 334 executes the action sound play processing when the action guidance sound play processing is not executed, a different action sound from the action sound when the action guidance sound play processing is being executed can be played. In addition, in this case, the sound stop time Ts can be different from the sound stop time Ts in the case where the action guidance sound play processing is being executed. In particular, in this case, the sound stop time Ts can be longer than in the case where the action guidance sound play processing is being executed. Or, in this case, there can be no sound stop time Ts, and the action sound play processing is not stopped but continues to be executed even if the action condition is determined to be continuously satisfied by the determination section 333.

[0210] Also, in the above embodiment, the plurality of different action sounds played during the execution of the action sound play processing are changed based on the motion time counted by the count section 335. However, in one modification, the action sound played during the execution of the action sound play processing can be changed in accordance with the size of the motion of the object detected by the non-contact sensor 21. For example, the larger the motion of the object detected by the non-contact sensor 21, the longer the length of the action sound, or the larger the volume, or the more the number of repetitions of the repeated sound can be increased. For example, the action sound is an effect sound of obtaining a coin in an arbitrary game, and as the motion of the object detected by the non-contact sensor 21 increases, the number of times the effect sound of obtaining a coin is repeated increases (the number of coins obtained increases) at the play of the action sound at one time.

[0211] In addition, in the above embodiment, whether the stop condition of stopping the action guidance sound play processing and the action sound play processing is satisfied is determined based only on the time when the action condition is satisfied. However, it can be configured that the larger the size of the motion of the object detected by the non-contact sensor 21, the sooner the stop condition is satisfied.

[0212] In addition, in one modification, the sound playback section 334 can execute the urgent mode in a case where the predetermined delay time (for example, 20 minutes) elapses from the timing at which the time is counted to the timing determined in accordance with the alarm time, and it is not determined that the separation condition is satisfied. The urgent mode is a mode in which the user is more strongly urged to wake up and get out of bed than in the normal mode before the delay time elapses.

[0213] In the present modification, in the urgent mode, the action guidance sound playback processing, the action sound playback processing, and the background sound playback processing are performed as in the normal mode. The action guidance sound, the action sound, and the background sound in the urgent mode are different from those in the normal mode. These sounds in the urgent mode are, for example, more urgent sounds than in the normal mode. In addition, the volumes of these sounds in the urgent mode can be larger than in the normal mode. In addition, the dozing time Tn, the pause determination time Tm, and the reset time Tr in the urgent mode can be shorter than in the normal mode. Furthermore, the sound stop time Ts in the urgent mode can be longer than in the normal mode.

[0214] Furthermore, in one modification, the determination section 333 can continue to determine whether the user is in bed after the get-out-of-bed sound playback processing is executed in a case where it is determined that the separation condition is satisfied. For example, the determination section 333 can continue to determine whether the user is in bed based on the movement of the object in the predetermined area in the bed B smaller than the bed B for a predetermined re-in-bed monitoring time from the time at which it is determined that the separation condition is satisfied.

[0215] In the present modification, in a case where it is determined by the determination section 333 that the user is in bed again after the get-out-of-bed condition is determined to be satisfied, the action guidance sound playback processing and the background sound playback processing are restarted as in the case where the timing at which the time is counted reaches the timing determined in accordance with the alarm time. Thus, in a case where it is determined by the determination section 333 that the user is in bed again after the get-out-of-bed condition is determined to be satisfied, the action guidance sound playback processing and the background sound playback processing are executed.

[0216] Furthermore, the sound playback section 334 can execute the urgent mode regardless of whether the get-out-of-bed condition is temporarily satisfied. Thus, the sound playback section 334 can execute the urgent mode in a case where the action guidance sound playback processing and the background sound playback processing are being executed although the predetermined delay time elapses from the timing at which the time is counted to the timing determined in accordance with the alarm time after the get-out-of-bed condition is temporarily satisfied.

[0217] The above describes preferred embodiments to which the present disclosure pertains, but the present disclosure is not limited to these embodiments, and various modifications and changes can be made within the scope of the recitations of the claims.
