[0010] Hereinafter, the embodiments will be described in detail with reference to the drawings. In the following description, like components are designated by like reference numerals.

[0011] <Overall structure> The configuration of a sound reproduction device 1 according to one embodiment will be described with reference to FIGS. 1 and 2. The sound reproduction device 1 is a device that outputs sound. The sound reproduction device 1 also has a timekeeping function (clock function) that keeps track of time. In this embodiment, the sound reproduction device 1 is used by being placed on an installation surface such as a table, floor, shelf, or bed headboard while the user is asleep. Specifically, the sound reproduction device 1 is, for example, a desk clock, a music player, a television, a game device, or a monitor device. In particular, in this embodiment, the sound reproduction device 1 is an alarm clock that wakes up a user who is asleep in front of the sound reproduction device 1.

[0012] Fig. 1 is a perspective view showing a schematic view of a sound reproduction device 1. As shown in Fig. 1, the sound reproduction device 1 includes a main body 10, a display 11 provided on the main body 10, and an operation unit 20 provided on the upper part of the main body 10. In this embodiment, as shown in Fig. 1, the main body 10 is configured as a cylindrical housing. However, the main body 10 may have any three-dimensional shape, such as a rectangular parallelepiped or semi-cylindrical shape.

[0013] The display 11 is disposed on the front surface of the main body 10 so that the user can see it from the front. The display 11 displays, for example, the current time. The current time may be displayed using numbers or using hour and minute hands. Note that the sound reproduction device 1 does not need to be equipped with the display 11, and may instead be equipped with, for example, hands such as hour and minute hands and a dial, as long as the user can recognize the current time and the alarm time described below.

[0014] The operation unit 20 is a member that allows the user to operate various functions of the sound reproduction device 1. In this embodiment, the operation unit 20 is a substantially cylindrical member provided above the main body 10. The operation unit 20 is attached so that it can be pushed into the main body 10 and can be rotated. When the user pushes the operation unit 20 into the main body 10 or rotates it relative to the main body 10, various functions of the sound reproduction device 1 are operated. Note that any member may be provided as the operation unit 20 as long as it can operate various functions of the sound reproduction device 1. Therefore, the operation unit 20 may be, for example, a button, a switch, a cross key, a touch panel arranged on the screen of the display 11, or the like.

[0015] 2 is a block diagram showing a schematic configuration of components of the sound reproduction device 1. As shown in FIG. 2, the sound reproduction 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, the speaker 12, the non-contact sensor 21, and the operation sensor 22 are electrically connected to the control unit 30 via signal lines. In addition, the sound reproduction device 1 further includes a battery (not shown) that supplies power to the display 11, the control unit 30, and the like. In this embodiment, the display 11, the speaker 12, the non-contact sensor 21, the operation sensor 22, and the control unit 30 are housed in the main body 10, but some of them may not be housed in the main body 10.

[0016] The display 11 is an example of an image display device that displays an image. The display 11 is electrically connected to the control unit 30 and displays an image in accordance with an image signal from the control unit 30. The display 11 displays an image in accordance with a computer program executed by the control unit 30. The display 11 is, for example, a liquid crystal display, an EL (Electro Luminescence) display, or a plasma display.

[0017] The speaker 12 is an example of a sound generator that generates sound. The speaker 12 is electrically connected to the control unit 30 and generates sound in accordance with a sound signal from the control unit 30. The speaker 12 generates sound in accordance with a computer program being executed by the control unit 30.

[0018] The non-contact sensor 21 is a detection unit that detects an object within a detection range without contact. The non-contact sensor 21 can detect the distance to an object within the detection range, the direction in which the object is located relative to the non-contact sensor 21, and the speed of the object in a non-contact manner over time. In this embodiment, the non-contact sensor 21 is disposed in the front of the main body 10 and detects objects within the detection range in front of the sound reproduction device 1. In particular, in this embodiment, the non-contact sensor 21 detects at least one of the distance to the object, the direction in which the object is located, and the speed of the object over time. The non-contact sensor 21 outputs, for example, an output signal that represents an object within the detection range. The output signal from the non-contact sensor 21 is input to the control unit 30.

[0019] In this embodiment, the non-contact sensor 21 is a millimeter-wave sensor. The millimeter-wave sensor emits millimeter-wave radio signals and receives signals reflected by surrounding objects. Based on the emitted radio signals and the received reflected signals, the sensor can detect at least one of the following over time: the distance from the millimeter-wave sensor to the object, the direction of the object relative to the millimeter-wave sensor, and the object's relative speed relative to the millimeter-wave sensor. That is, the millimeter-wave sensor can detect the position of surrounding objects. The millimeter-wave sensor emits radio signals over a predetermined angular range and receives reflected signals from objects located within a predetermined distance from the millimeter-wave sensor. Therefore, the detection range of the millimeter-wave sensor is the predetermined angular range within which the millimeter-wave sensor emits radio signals and the distance from the millimeter-wave sensor is within the predetermined distance. Using a millimeter-wave sensor as the non-contact sensor 21 in this manner enables non-contact detection of the position and speed of an object, particularly a user, with fast response speed and relatively high accuracy. Furthermore, the movement of the object can be calculated based on the position and speed of the object detected over time.

[0020] Note that, as long as the distance to an object, the direction in which the object is located, and the speed of the object can be detected in a non-contact manner, sensors other than a millimeter wave sensor, such as an infrared sensor, an ultrasonic sensor, or a microwave sensor, may be used as the non-contact sensor 21. Furthermore, as long as an object within the detection range can be detected in a non-contact manner, other types of sensors, such as a temperature sensor, may be used as the detection unit instead of the non-contact sensor 21. Furthermore, as the detection unit, a sensor that can detect the movement of an object within the detection range may be used instead of the non-contact sensor 21.

[0021] The operation sensor 22 is an example of an operation detection unit that detects an operation performed by a user on the operation unit 20. In this 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 has been pressed. Furthermore, 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 has been rotated. The output signal from the operation sensor 22 is input to the control unit 30.

[0022] Note that a sensor according to the type of operation unit 20 is used as the operation sensor 22. For example, when a button is used as the operation unit 20, a sensor whose output signal changes depending on whether the button is pressed or not is used as the operation sensor 22. Furthermore, when a touch panel is used as the operation unit 20, a sensor that outputs an output signal indicating the position where a finger touches is used as the operation sensor 22.

[0023] <Configuration and operation of the control unit> Next, the configuration and operation of the control unit 30 will be described with reference to Figures 3 and 4. The control unit 30 transmits control signals to the display 11, speaker 12, etc. in accordance with a running computer program based on 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. The communication interface 31, the memory 32, and the processor 33 may be separate circuits, or may be configured as a single integrated circuit.

[0024] The control unit 30 controls the sounds output by the speaker 12. In this embodiment, the control unit 30 plays different types of sounds, including an action-inducing sound, a background sound, an action sound, and a bed-getting sound, and outputs them from the speaker 12. In particular, in this embodiment, the control unit 30 plays the action-inducing sound, the background sound, the action sound, and the bed-getting sound at different times and for different periods based on the detection results of the non-contact sensor 21, etc., to promote awakening of the sleeping user.

[0025] The action prompting sound is an example of a first sound that is played when the time being measured reaches a time determined according to the set alarm time, and is, for example, a sound effect (including a voice message). The action prompting sound is, for example, the footsteps of a character walking or running in a given game. The action prompting sound may also be music.

[0026] The action-inducing sound may be stopped if it is determined that an object of a certain size or larger is continuously moving during playback, or may be played again when a predetermined snooze time has elapsed after the action-inducing sound has been stopped.

[0027] The background sound is an example of a fourth sound that is played when the clock reaches a time determined according to the set alarm time and does not stop playing even if a certain amount of movement of an object occurs. Note that the fourth sound is included in the first sound that is played when the clock reaches a time determined according to the set alarm time. Therefore, the background sound is also an example of the first sound.

[0028] The background sound is not stopped even if a movement of a certain size of object is detected during playback of the background sound, but is stopped when it is determined that an object is moving from within a predetermined sleeping area to outside the sleeping area. The background sound is a sound different from the action-inducing sound, the action sound, and the bed-exiting sound, and is, for example, music. Note that the background sound may be a sound effect.

[0029] The action sound is an example of a second sound that is played when it is determined based on the detection result of the non-contact sensor 21 that there is movement of an object of a certain size. In other words, the action sound is played when the user's body is moving significantly, not when the user is simply breathing. The action sound is a sound that is different from the action-inducing sound, and is, for example, a sound effect (including a voice message). The action sound is, for example, a sound effect that is played in accordance with the movement of a character in a given game. Specifically, the action sound is, for example, a sound effect that is played when a character jumps, a sound effect that is played when a character operates an item, a sound effect that is played when an enemy character attacks, or a sound effect that is played when a character acquires an item in a given game.

[0030] The action sound may be music. In particular, when the action prompting sound and the action sound are both music, the action sound is music different from the music of the action prompting sound. In this case, the action sound is, for example, music related to the music of the action prompting sound but different from the music of the action prompting sound. Specifically, for example, the music of the action prompting sound is a piece of music without vocals added, and the action sound is the same piece of music as the action prompting sound but with vocals added.

[0031] The bed exit sound is an example of a third sound that is played when, based on the detection result of the non-contact sensor 21, an object that was detected within the predetermined sleeping area is no longer detected within the predetermined sleeping area and is instead detected outside the predetermined sleeping area, or when it is determined that an object is moving from within the predetermined sleeping area to outside the sleeping area. For example, the bed exit sound is played when the user appears to have left the bed. The bed exit sound is a sound that is different from the action-inducing sound and the action sound, and is, for example, a sound effect. In particular, the bed exit sound is a sound effect (including a voice message) that is played when something is accomplished. The bed exit sound is, for example, a sound effect that is played when a certain stage is cleared in a certain game. Specifically, the bed exit sound is, for example, a fanfare. The bed exit sound may be music.

[0032] The communication interface 31 is a circuit for connecting the control unit 30 to other electronic components in the main body 10, that is, the display 11, the speaker 12, the non-contact sensor 21, and the operation sensor 22.

[0033] The memory 32 is an example of a storage unit that stores data. The memory 32 is a storage medium that stores data, and includes, for example, a volatile semiconductor memory or a non-volatile semiconductor memory. In addition, the memory 32 may include removable media such as a memory card or an optical disk. The memory 32 stores computer programs executed by the processor 33. The memory 32 also stores various data used by the running program, such as output signals from the non-contact sensor 21.

[0034] Furthermore, the memory 32 stores data of sounds to be played by the control unit 30. In particular, the memory 32 stores data of the above-mentioned action-inducing sounds, action sounds, bed-exit sounds, and background sounds. Therefore, the processor 33 obtains data of sounds to be played from the memory 32 and plays the sounds based on the obtained data, thereby outputting the sounds from the speaker 12.

[0035] In this embodiment, the memory 32 stores a plurality of sets, a plurality of different action prompting sounds, a plurality of different action sounds, a plurality of different bed getting-out sounds, and a plurality of different background sounds. The memory 32 also stores these sounds, images to be displayed on the display, and the like, in association with each set. Therefore, each set is associated with an action prompting sound different from the other sets, an action sound different from the other sets, a bed getting-out sound different from the other sets, and a background sound different from the other sets.

[0036] Specifically, for example, the multiple sets correspond to multiple different games, and sounds and images related to each game are stored in memory 32 in association with the set. For example, with a certain set, the footsteps of a character from the game corresponding to the set are associated as action-inducing sounds, the movement sounds of a character jumping or other actions from the game are associated as action sounds, the sound effects of clearing a stage in the game are associated as bed-leaving sounds, and the background music of the game is associated as background sounds. Furthermore, a set corresponding to a certain game is associated with an image of a character from the game or an image of an item used in the game. Note that multiple sets may correspond to a single game. In this case, multiple different sets corresponding to the same game may contain partially identical sounds.

[0037] The memory 32 does not necessarily have to store a set. In this case, the memory 32 stores a plurality of different action-inducing sounds, a plurality of different action sounds, a plurality of different bed-getting sounds, and a plurality of different background sounds, regardless of the set. Alternatively, the memory 32 may store one action-inducing sound, one action sound, one bed-getting sound, and one background sound.

[0038] Additionally, in this embodiment, the memory 32 stores various settings made by the user. For example, the memory 32 stores an alarm time set by the user. The memory 32 also stores a set selected by the user from among the sets stored in the memory 32.

[0039] The processor 33 has one or more central processing units (CPUs) and their peripheral circuits. The processor 33 may further have other arithmetic circuits such as a logic unit or a numerical operation unit. The processor 33 executes various processes based on computer programs stored in the memory 32. For example, the processor 33 executes control processes for the display 11 and the speaker 12 and outputs control signals to the display 11 and the speaker 12. Thus, the processor 33 controls the images displayed on the display 11 and reproduces sounds.

[0040] 3 is a functional block diagram of the processor 33 of the control unit 30. As shown in FIG. 3, the processor 33 has a timing unit 331, a calculation unit 332, a determination unit 333, a sound reproduction unit 334, a counting unit 335, and a setting unit 336. Each of these units in the processor 33 is a functional module realized by, for example, a computer program running on the processor 33. Alternatively, each unit in the processor 33 may be implemented in the control unit 30 as an independent integrated circuit, microprocessor, or firmware.

[0041] The timekeeping unit 331 keeps time. For example, the timekeeping unit 331 keeps time by counting signals output from a circuit that oscillates at a predetermined cycle and adding the count to an initial time. The time kept by the timekeeping unit 331 basically represents the current time. The timekeeping unit 331 may have a function to correct the kept time based on, for example, a standard radio wave that represents standard time received by a receiver (not shown). The kept time is displayed on the display 11.

[0042] The calculation unit 332 calculates the magnitude of movement of an object within the detection range of the non-contact sensor 21 based on the detection result by the non-contact sensor 21. The calculation unit 332 may calculate the magnitude of movement of an object within a motion detection area (second area) that is narrower than (or the same area as) the detection range of the non-contact sensor 21. The output signal of the non-contact sensor 21 is input to the calculation unit 332, and the calculation unit 332 inputs the detection result to the determination unit 333.

[0043] The calculation unit 332 calculates the magnitude of the object's movement based on, for example, a change in the distance to the object within the detection range, a change in the direction in which the object is located, and the object's speed. In this embodiment, the non-contact sensor 21 is a millimeter wave sensor. Therefore, the calculation unit 332 calculates the magnitude of the object's movement based on the time-series detection results of the distance from the millimeter wave sensor to the object within the detection range, which are detected based on the radio wave signal and the reflected signal. Alternatively, the calculation unit 332 calculates the magnitude of the object's movement based on the time-series detection results of the direction in which the object is located relative to the millimeter wave sensor, which are detected based on the radio wave signal and the reflected signal. Alternatively, the calculation unit 332 calculates the magnitude of the object's movement based on the object's relative speed relative to the millimeter wave sensor, which is detected based on the radio wave signal and the reflected signal.

[0044] The determination unit 333 determines whether or not a given condition is satisfied based on the detection result by the non-contact sensor 21. The output signal of the non-contact sensor 21 is input to the determination unit 333, and the determination unit 333 inputs the determination result to the sound reproduction unit 334.

[0045] The determination unit 333 determines whether a predetermined operation condition is satisfied based on the detection result by the non-contact sensor 21. The operation condition is a condition that is satisfied when the magnitude of the movement of an object within the operation detection area calculated by the calculation unit 332 is equal to or greater than a predetermined magnitude. The predetermined magnitude is, for example, the magnitude of the object movement calculated by the calculation unit 332 when the user makes a movement of equal to or greater than a predetermined magnitude (for example, sitting up, rolling over, moving arms and legs, etc.). The predetermined magnitude is, for example, greater than the magnitude of the object movement calculated by the calculation unit 332 when there is chest movement due to the user breathing. Therefore, the operation condition is not satisfied by chest movement due to breathing while the user is resting in bed.

[0046] FIG. 4 is a diagram schematically illustrating the detection range of the non-contact sensor 21 when the sound reproduction device 1 is installed next to a bed B where a user sleeps. In the example illustrated in FIG. 4, the sound reproduction device 1 is installed next to the bed B with its front surface facing the bed B. As illustrated in FIG. 4, the detection range of the non-contact sensor 21 covers a certain angular range (the area indicated by gray in the figure). Furthermore, the non-contact sensor 21 can perform detection up to a distance from the non-contact sensor 21 that is sufficiently larger than the size of a typical bed B (the area indicated by gray in the figure). Therefore, the non-contact sensor 21 can detect the movement of an object up to a distance beyond the bed B within this angular range. Note that, within the angular range of the detection range illustrated in FIG. 4, a narrower range within a predetermined angular range can detect the position of an object more accurately than a range wider than the predetermined angular range. In this way, the range in which the position of an object can be detected more accurately may be set as the angular range (detection range) in which detection is performed by the non-contact sensor 21. Furthermore, an area within a predetermined lower limit distance (for example, 15 cm) from the non-contact sensor 21 may be set as an invalid area in which no object detection is performed.

[0047] In this embodiment, the area where bed B is located, i.e., the area where the sleeping user is located, is set in advance by the setting unit 336. Then, the determination unit 333 determines that the motion condition is satisfied when it is determined that there is a movement of an object of a predetermined size or more within the detection range and within the area where bed B is located (hereinafter referred to as the "motion detection area") based on the detection result of the non-contact sensor 21. As a result, even if an object moves outside the motion detection area, the motion condition is not satisfied, and it is possible to prevent the motion condition from being determined to be satisfied by the movement of someone other than the user on bed B.

[0048] The motion detection area may be any area within the detection range other than the area where the bed B is located. For example, the motion detection area may be an area within the detection range and within a predetermined upper limit distance (e.g., 3.5 m) from the sound reproduction device 1 (i.e., from the non-contact sensor 21), an area within the detection range and within the sleeping area A described later, or the like.

[0049] Furthermore, the motion detection area may be an area that does not include within a predetermined lower limit distance (for example, 15 cm) from the sound reproduction device 1 (i.e., from the non-contact sensor 21). For example, even if the user waves their hand slightly, if the position of the hand is close to the non-contact sensor 21, it may be determined that there has been a large user movement and that the motion condition has been satisfied; however, by not including an area within the lower limit distance in the motion detection area, such a possibility can be reduced.

[0050] Furthermore, the determination unit 333 determines whether a predetermined leaving condition is satisfied based on the detection result by the non-contact sensor 21. The leaving condition is a condition that is satisfied when it is determined that there is movement of an object moving from within a preset sleeping area (first area) A to outside the sleeping area A. In this embodiment, the area where the user sleeps is preset as a predetermined sleeping area (area A in the figure) by the setting unit 336. The sleeping area A is set as an area larger than the actual bed B so that the leaving condition is not determined to be satisfied even if part of the user (such as hands or feet) moves slightly outside the bed B while sleeping.

[0051] Here, as shown in Fig. 4, consider the case where the user moves from inside bed B to outside bed B within the detection range of non-contact sensor 21, that is, the case where the user moves in the direction indicated by the white arrow in Fig. 4. In such a case, non-contact sensor 21 detects the movement of a large object indicating the user's movement, etc., inside preset sleeping area A and then outside sleeping area A. Therefore, determination unit 333 determines that the leaving condition is satisfied when the output signal of non-contact sensor 21 indicates that the movement of an object equal to or larger than the predetermined size occurred inside sleeping area A and then outside sleeping area A.

[0052] On the other hand, as shown in FIG. 4 , consider the case where the user moves from within the angular range of the detection range of non-contact sensor 21 to outside the angular range, i.e., the user moves in the direction indicated by the hatched arrow in FIG. 4 . In such a case, non-contact sensor 21 does not detect the movement of an object outside sleeping area A. Here, even if the user moves from within the angular range of the detection range of non-contact sensor 21 to outside the angular range, as long as the user is on bed B, non-contact sensor 21 may be able to detect small movements, such as movement of the bed due to the user's breathing. On the other hand, if the user moves from within the angular range of the detection range of non-contact sensor 21 to outside the angular range and then moves out of bed B, even small movements will not be detected by non-contact sensor 21 after the user's movement. Therefore, in this embodiment, determination unit 333 determines that the leaving condition is satisfied when the output signal of non-contact sensor 21 indicates that no movement of even an object smaller than the predetermined size has occurred within sleeping area A for a predetermined reference time after the movement of an object larger than the predetermined size has occurred within sleeping area A.

[0053] 4, the sleeping area (first area) may include an area within the detection range between area A in FIG. 4 and sound reproduction device 1 (i.e., an area between area A in FIG. 4 and non-contact sensor 21). This prevents the user from determining that the leaving condition is satisfied when the user stretches out his or her hand to operate sound reproduction device 1. Furthermore, determination unit 333 may determine that the user has gone to bed based on the movement of an object in a predetermined area within bed B that is smaller than bed B.

[0054] The sound playback unit 334 plays a sound, which is then output from the speaker 12. When a predetermined condition is met, the sound playback unit 334 executes an action-inducing sound playback process for playing an action sound, an action sound playback process for playing an action sound, a bed-exit sound playback process for playing a bed-exit sound, or a background sound playback process for playing a background sound. Furthermore, when a predetermined condition is met, the sound playback unit 334 stops playback of the action-inducing sound, action sound, bed-exit sound, or background sound. Details of sound playback control by the sound playback unit 334 will be described later.

[0055] The counting unit 335 counts the time during which the determination unit 333 determines that the operation conditions are satisfied as the operation time. In particular, the counting unit 335 counts the time during which the determination unit 333 determines that the operation conditions are satisfied while the action-inducing sound is being played as the operation time. Therefore, the operation time represents the time during which the operation conditions are satisfied while the action-inducing sound is being played. Furthermore, even after the operation conditions are satisfied and counting of the operation time has started, the counting unit 335 stops counting the operation time while the operation conditions are not satisfied.

[0056] The setting unit 336 performs settings necessary for the operation of the sound reproduction device 1, such as sound reproduction. In this embodiment, the setting unit 336 sets various items based on input by the user via the operation unit 20. The setting unit 336 sets, for example, an alarm time, which is the time when the alarm should start, sleeping area A, and the area where bed B is located. The sleeping area A and the area where bed B is located are set by the user inputting, for example, the placement position of the sound reproduction device relative to the bed, the distance between the sound reproduction device 1 and bed B, and the size of bed B via the operation unit 20. The setting unit 336 also sets a set selected by the user from multiple sets stored in the memory 32. The setting unit 336 sets these items based, for example, on an output signal from the operation unit 20 operated by the user. The items set by the setting unit 336, such as the alarm time set by the user via the setting unit 336, sound-related settings, sleeping area A, and the area where bed B is located, are stored in the memory 32.

[0057] Note that once the set selected by the user is set by the setting unit 336, the sound playback unit 334 plays sounds during the sound playback process in accordance with the set that has been set. The sound playback unit 334 plays an action-inducing sound associated with the set selected by the user during the action-inducing sound playback process, and plays an action sound associated with the set selected by the user during the action sound playback process. In addition, the sound playback unit 334 plays a bed exit sound associated with the set selected by the user during the bed exit sound playback process, and plays a background sound associated with the set selected by the user during the background sound playback process. Thus, the sound playback unit 334 plays a sound based on the user's selection from among a plurality of different sounds. This allows sounds to be played according to the user's preferences.

[0058] Alternatively, the setting unit 336 may set a sound selected by the user from among multiple different sounds stored in the memory 32, rather than setting a set of sounds. In this case, for example, the setting unit 336 sets one action inducing sound selected by the user from among multiple action inducing sounds as the action inducing sound to be played during the action inducing sound playback process. Similarly, the setting unit 336 sets one action sound, one bed exit sound, and one background sound selected by the user from among multiple action sounds, multiple bed exit sounds, and multiple background sounds as the action sound to be played during the action sound playback process, the bed exit sound to be played during the bed exit sound playback process, and the background sound to be played during the background sound playback process, respectively. As a result, the sound playback unit 334 plays the action inducing sound selected by the user during the action inducing sound playback process, and plays the action sound selected by the user during the action sound playback process. In addition, the sound playback unit 334 plays the bed exit sound selected by the user during the bed exit sound playback process, and plays the background sound selected by the user during the background sound playback process. In this way, sounds are played back based on the user's selection, so that sounds are played back in accordance with the user's preferences.

[0059] The setting by the setting unit 336 does not necessarily have to be performed based on an output signal from the operation unit 20. For example, when the sound reproduction device 1 is set to the bed area detection mode, the setting unit 336 may set an area where the movement of an object is detected by the non-contact sensor 21 (for example, an area where the movement is detected due to the user intentionally moving around on the bed) as the area where the sleeping area A and the bed B are located.

[0060] <Sound playback control> Next, sound reproduction control in the sound reproduction device 1 configured as above will be described with reference to Fig. 5 to Fig. 8. Fig. 5 is a time chart showing the volume of the entire sound output by the sound reproduction device 1, the satisfaction of the operating conditions, the operating time, and the satisfaction of the withdrawal conditions. Fig. 6 is a time chart showing the volume of each sound in Fig. 5. The horizontal axis in Fig. 5 and Fig. 6 represents the time measured by the timing unit 331 (hereinafter also referred to as "measured time").

[0061] 5 and 6, the alarm time is set to time t0. Therefore, the sound replay unit 334 stops replaying all sounds, including the action prompt sound, action sound, bed exit sound, and background sound, until time t0.

[0062] In this embodiment, the sound playback unit 334 starts background sound playback processing when the measured time reaches a time determined according to the alarm time. In addition, the sound playback unit 334 starts action prompting sound playback processing when the measured time reaches a time determined according to the alarm time. The time determined according to the alarm time may be the alarm time, a time a predetermined time before the alarm time, or a time a predetermined time after the alarm time. This allows the user to be notified that the measured time has reached the alarm time. Note that the background sound playback processing and the action prompting sound playback processing may be started at the same time or at different times.

[0063] In the examples shown in Figures 5 and 6, at time t0, which is the alarm time, the sound playback unit 334 starts background sound playback processing to play background sound, and then gradually increases the volume. In this embodiment, when time t1, which is a certain amount of time after time t0, is reached, the sound playback unit 334 temporarily stops increasing the volume of the background sound until time t2. The period from time t0 to time t2 is an intro period, during which the volume of the sound from the sound playback device 1 is kept low at a first volume v1. This prevents a sleeping user from being surprised by a sudden output of a loud sound. Note that the intro period is not necessarily required.

[0064] When the intro period ends at time t2, the sound playback unit 334 then starts an action-inducing sound playback process to play an action-inducing sound, gradually increasing the volume of the action-inducing sound. Therefore, in this embodiment, playback of the action-inducing sound starts after a predetermined intro period has elapsed from the alarm time. In other words, the playback process to play the action-inducing sound can be said to be executed when the measured time reaches a time determined according to the alarm time. Note that, as described above, the intro period is not necessarily required, and therefore the action-inducing sound playback process may be started at time t0, which is the alarm time. In addition, the sound playback unit 334 also increases the volume of the background sound after time t2. Note that, in this embodiment, the volume of the action-inducing sound is louder than the volume of the background sound.

[0065] In this embodiment, when time t3 is reached, which is a certain amount of time that has elapsed since time t2, the sound playback unit 334 maintains the volume of the background sound at a constant fourth volume v4. Then, when time t4 is reached, which is a certain amount of time that has elapsed since time t2, the sound playback unit 334 maintains the volume of the action-guiding sound at a constant fifth volume v5. In this embodiment, the fifth volume v5 is louder than the fourth volume v4. Note that in this embodiment, the timing at which the background sound reaches the fourth volume v4 (time t3) and the timing at which the action-guiding sound reaches the fifth volume v5 (time t4) are different, but they may also be the same timing.

[0066] During the execution of the action prompting sound replay process or the background sound replay process, some image may be displayed on the display 11. For example, if the action prompting sound is the footsteps of a certain character, an image of the character walking or running may be displayed on the display 11 during the reproduction of the action prompting sound.

[0067] When the action-inducing sound is played back and the user starts moving on the bed B, the determination unit 333 determines that the movement satisfies the operation condition. In this embodiment, if the determination unit 333 determines that the operation condition is satisfied while the action-inducing sound is being played back, the sound playback unit 334 starts an action sound playback process to play the action sound. Therefore, in the example shown in FIGS. 5 and 6, the action sound playback process starts at time t5. The volume of the action sound is lower than the fifth volume v5. In this way, the action sound is played back when the determination unit 333 determines that the operation condition is satisfied, thereby encouraging the user to move their body. As a result, it is possible to encourage a sleeping user to wake up. Furthermore, because the volume of the action sound is lower than the fifth volume v5, the user will move their body to reduce the volume of the sound output by the sound playback device 1, thereby encouraging the user to wake up.

[0068] During the action sound playback process, some image may be displayed on the display 11 in conjunction with the playback of the action sound. For example, if the action sound is a sound effect for obtaining an item, an image of the item may be displayed on the display 11.

[0069] Additionally, in this embodiment, simultaneously with the execution of the action sound playback process, the sound playback unit 334 reduces the volumes of the action prompting sound and the background sound to the third volume v3 and the second volume v2, respectively. In this embodiment, the third volume v3 is lower than the fourth volume v4, but may be higher than the fourth volume v4 as long as it is lower than the fifth volume v5. Also, in this embodiment, the second volume v2 is higher than the third volume v3 and higher than the first volume v1. By reducing the volumes of the action prompting sound and the action sound in this manner, the user can more easily hear the action sound. Note that, during the execution of the action sound playback process, the volume of at least one of the action prompting sound and the background sound may be set to zero.

[0070] The action sound playback process is executed while the determination unit 333 determines that the operation conditions are satisfied during the execution of the action-inducing sound playback process or the background sound playback process. In particular, in this embodiment, the action sound playback process is executed while the operation time counted by the counting unit 335 is not zero. In the example shown in FIGS. 5 and 6, the user moves significantly on the bed B after time t5, and therefore the operation time continues to be counted by the counting unit 335 after time t5. Therefore, in the example shown in FIGS. 5 and 6, the sound playback unit 334 continuously executes the action sound playback process after time t5.

[0071] 5 and 6, during the execution of the action sound reproduction process, the counting unit 335 counts the time during which the determination unit 333 determines that the operation conditions are satisfied as the operation time. In this embodiment, when the operation time counted by the counting unit 335 reaches a predetermined sound stop time Ts (first time; for example, 1 second or more, 2 seconds or more, or 2.5 seconds or more, and 10 seconds or less, 5 seconds or less, or 3 seconds or less) (time t6), the sound reproduction unit 334 stops the action sound reproduction process. In other words, when the total time during which the determination unit 333 determines that the operation conditions are satisfied reaches the sound stop time Ts, the sound reproduction unit 334 stops the action sound reproduction process.

[0072] In this embodiment, when a stop condition is satisfied, that is, when the action time counted by the counting unit 335 reaches the sound stop time Ts, the sound playback unit 334 stops the action-inviting sound playback process, thereby stopping the playback of the action-inviting sound. That is, the action-inviting sound is stopped by the user moving for a certain period of time while the action-inviting sound is being played. Therefore, when the action-inviting sound is played, the user moves their body to stop the playback of the action-inviting sound, which can encourage the user to wake up. After the action-inviting sound is stopped, the action-inviting sound playback process is not executed for a snooze time Tn, which will be described later. Furthermore, in this embodiment, when the action time counted by the counting unit 335 reaches the sound stop time Ts, the sound playback unit 334 reduces the volume of the background sound to the first volume. Therefore, when the user moves their body, the volume of the background sound is also reduced, which encourages the user to move their body more actively and encourages the user to wake up. The volume of the background sound may or may not be reduced to a volume different from the first volume when the operation time counted by the counting unit 335 reaches the sound stop time Ts.

[0073] In this embodiment, the sound playback unit 334 stops the action prompting sound playback process and the action sound playback process when the action time counted by the counting unit 335 reaches the sound stop time Ts. However, the sound playback unit 334 may stop the action prompting sound playback process and the action sound playback process, for example, when an action continuation value calculated by dividing the action time (action duration) counted by the counting unit 335 by the maximum action duration equivalent to the above-mentioned sound stop time Ts reaches 100%. In other words, it can be said that the sound playback unit 334 stops the action prompting sound playback process and the action sound playback process when a stop condition indicating that the action time counted by the counting unit 335 has reached the predetermined sound stop time Ts is satisfied.

[0074] Furthermore, the sound playback unit 334 may stop only the action prompting sound playback process when the stop condition is satisfied, and continue the action sound playback process as long as the determination unit 333 determines that the operation condition is satisfied. Alternatively, the sound playback unit 334 may stop only the action prompting sound playback process without stopping the action prompting sound playback process when the stop condition is satisfied. In this case, the volume of the action prompting sound may be reduced when the stop condition is satisfied.

[0075] In this embodiment, as shown in Figures 5 and 6, action sounds are played intermittently during the action sound playback process. Therefore, action sounds are played multiple times during the action sound playback process. In other words, in this embodiment, action sounds are played intermittently multiple times during the action sound playback process from the start of the action sound playback process until the action prompting sound playback process is stopped as a result of the stop condition being satisfied. In the example shown in Figures 5 and 6, action sounds are played eight times during the action sound playback process.

[0076] Additionally, in this embodiment, the sound playback unit 334 plays action sounds during the execution of the action sound playback process so that the time during which the determination unit 333 determines that the action condition is satisfied between one action sound and the next action sound to be played (hereinafter referred to as the "action determination time between sounds") changes depending on the number of times the action sound has already been played in one action sound playback process. For example, the sound playback unit 334 plays action sounds so that the action determination time between sounds becomes longer as the number of times the action sound has already been played increases. The sound playback unit 334 may play action sounds so that the action determination time between sounds becomes longer as the action time counted by the counting unit 335 becomes longer. Therefore, for example, the action determination time between the first and second playbacks of the action sound after the start of the action sound playback process is shorter than the action determination time between the second and third playbacks of the action sound. If the motion determination time between sounds is long from the start of the action sound playback process, the user will lose motivation to move their body because the action sounds are difficult to play, but in this embodiment, the motion determination time between sounds is short at the start of the action sound playback process, so the user does not lose motivation to move their body. Also, since a user who has been moving their body for a certain period of time will move their body with the goal of hearing the next action sound, the motion determination time becomes longer as time passes from the start of the action sound playback process, which can further awaken the user.

[0077] Furthermore, in this embodiment, the multiple action sounds played during the execution of the action sound playback process are at least partially different sounds. For example, the action sounds are at least partially different sound effects. Therefore, the memory 32 stores multiple different tracks to be played as action sounds corresponding to one set, and the multiple different tracks are played during the execution of the action sound playback process. The different sounds are, for example, different sound effects (for example, in a given game, a sound effect played when a character jumps, a sound effect played when a character manipulates an item, a sound effect played when a character obtains an item, etc.). Furthermore, the different sounds may be the same sound effect but with different pitches or tempos.

[0078] In this embodiment, the multiple different action sounds played during the action sound playback process are changed based on the action time counted by the counting unit 335. Therefore, for example, an action sound with a relatively short action time (from the first action sound to the fourth action sound) is set as a sound effect played when a character jumps in a given game, and an action sound with a relatively long action time (from the fifth action sound to the eighth action sound) is set as a sound effect played when a character acquires an item in a given game. This allows the user to know the action time counted by the counting unit 335 and intuitively grasp the amount of time an action should be continued before stopping the action prompting sound, etc. Furthermore, the action sounds to be played may be predetermined according to the order in which the action sounds are played.

[0079] Furthermore, the action sound played when the action time reaches the sound stop time Ts (the last action sound played during execution of the action sound playback process) may be a sound effect different from other action sounds, such as a sound effect played when an enemy is defeated in a given game, etc. This allows the user to recognize that the action time has reached the sound stop time Ts and that the action prompt sound playback process and the action sound playback process will end.

[0080] The different action sounds played during the action sound playback process may be changed based on the remaining time until the time that satisfies the action condition reaches the sound stop time Ts. Alternatively, the different action sounds played during the action sound playback process may all be the same sound.

[0081] Next, control of the playback of action sounds when there is a period during which the user does not move significantly on bed B while the action sound playback process is being executed will be described with reference to Fig. 7. Fig. 7 is a time chart showing the volume, operation conditions, and operation time counted by counting unit 335 of the action prompting sound and action sound during execution of the action sound playback process.

[0082] 7, when the determination unit 333 determines that the operation condition is satisfied at time t5, the counting unit 335 starts counting the operation time. In the example shown in FIG. 5a The user moves significantly on bed B from time t5 to time t 5a Therefore, the sound reproducing unit 334 determines that the operating conditions are satisfied from time t5 to time t 5a During this time, the action sound reproducing process is executed, and the action sound is reproduced intermittently.

[0083] In the example shown in FIG. 5aAfter that, the user stops moving, and as a result, at time t 5a After that, the determination unit 333 determines that the operating conditions are not satisfied. The count unit 335 counts the time during which the determination unit 333 determines that the operating conditions are satisfied as the operating time. 5a Thereafter, the operation time counted by the counting unit 335 does not increase but remains constant. 5a Since the action time counted by the counting unit 335 has not reached zero, the action sound reproducing process continues.

[0084] In this embodiment, the counting unit 335 resets the operation time to zero when the non-operation time, which is the time during which the determination unit 333 continuously determines that the operation condition is not satisfied after the counting unit 335 starts counting the operation time, reaches a predetermined reset time (fourth time) Tr. The reset time Tr is shorter than the sound stop time Ts, and is, for example, 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 operates continuously so that the counting unit 335 does not return to zero due to the user's inactivity over the reset time, thereby encouraging the user to operate.

[0085] In the example shown in Figure 7, time t 5a Thereafter, the determination unit 333 determines that the operating conditions are not satisfied for a period of time equal to or longer than the reset time Tr. Therefore, the determination unit 333 determines that the operating conditions are not satisfied from the time t 5a After the reset time Tr has elapsed from time t 5b At time t, the operation time counted by the counting unit 335 is reset to zero. 5b The counting process in the counting unit 335 may be ended at time t 5b At this point, the action sound playback process is stopped.

[0086] In addition, in this embodiment, when the action time counted by the counting unit 335 is reset to zero, the volume of the action prompting sound is increased from the third volume v3 to the fifth volume v5. At this time, the volume of the background sound is increased from the second volume v2 to the fourth volume v4. In other words, when the action time counted by the counting unit 335 is reset to zero, the volume is returned to the state before the action sound playback process was started. Note that the volume of the action prompting sound and the volume of the background sound do not have to be increased when the action time counted by the counting unit 335 is reset to zero. In this case, the volume of the action prompting sound and the volume of the background sound are increased when a predetermined time has passed during which the determination unit 333 has determined that the action condition is not satisfied, which is longer than the reset time, or when a predetermined time has passed since the action time counted by the counting unit 335 was reset to zero.

[0087] In this embodiment, when the time determined to not satisfy the motion conditions after the start of counting the motion time reaches the reset time Tr, the motion time counted by the counting unit 335 is reset to zero. However, the motion time counted by the counting unit 335 does not necessarily have to be reset to zero if it is changed based on the time determined to not satisfy the motion conditions after the start of counting the motion time. For example, the motion time counted by the counting unit 335 is shortened as the time determined to not satisfy the motion conditions becomes longer. This can encourage the user to move, since if the user stops moving, the time required to stop the action-inducing sound becomes longer. Alternatively, the counted motion time does not need to be changed even if the time determined to not satisfy the motion conditions occurs after the start of counting the motion time.

[0088] Furthermore, the sound stop time Ts may be changed based on the time it is determined that the action conditions are not satisfied after the start of counting the action time, rather than the action time counted by the counting unit 335. In this case, for example, the sound stop time Ts is increased as the time it is determined that the action conditions are not satisfied after the start of counting the action time increases. This increases the time required to stop the action-inducing sound when the user stops moving, thereby encouraging the user to move.

[0089] In the example shown in FIG. 5a From time t 5c After the determination unit 333 determines that the operating conditions are not satisfied until time t 5c At time t, the user starts to move again, and the determination unit 333 determines that the movement condition is satisfied. 5c At step 335, the action sound reproducing process is started again, the volume of the action inducing sound and the background sound is lowered, and the counting unit 335 starts counting the operation time.

[0090] In the example shown in FIG. 7, after that, at time t 5d From time t 5e During this time, the user stops moving, and the determination unit 333 again determines that the operation condition is not satisfied. 5d From time t 5e The time interval from time t 5e Thereafter, the user continues to move, and as a result, the movement time counted by the counting unit 335 increases, and finally, at time t6, the movement time reaches the sound stop time Ts. When the movement time reaches the sound stop time Ts in this way, the stop condition is satisfied, and the sound playback unit 334 stops the action-inducing sound playback process and the action sound playback process, similar to the examples shown in Figures 5 and 6.

[0091] 5 and 6, the action prompting sound playback process and the action sound playback process are stopped at time t6, and therefore, from time t6 onwards, the background sound is played at a relatively low first volume v1. In the example shown in Figures 5 and 6, the user stops moving after time t6, and therefore, the determination unit 333 determines that the action condition is not satisfied thereafter.

[0092] In this embodiment, the sound playback unit 334 resumes the action-inducing sound playback process when a resume condition is satisfied after the action-inducing sound playback process is stopped due to the stop condition being satisfied. In this embodiment, the resume condition is a condition that is satisfied when a snooze time (second time) Tn has elapsed since the action-inducing sound playback process was stopped and the non-operation time during which the determination unit 333 has determined that the operation condition is not satisfied reaches a pause determination time (third time) Tm. The snooze time Tn is, for example, three minutes or less. It may be longer or shorter than three minutes. The pause determination time Tm is shorter than the snooze time, for example, 30 seconds. It may be longer or shorter than 30 seconds.

[0093] 5 and 6, at time t7, the snooze time Tn has elapsed since time t6, and immediately before time t7, the determination unit 333 has continuously determined that the operating condition is not satisfied over the pause determination time Tm. Therefore, in the example shown in Fig. 5 and 6, the action-guiding sound playback process is resumed at time t7.

[0094] In this manner, in this embodiment, if the user stops moving after performing an action and is now on bed B, the action-inducing sound is played again. If the user stops moving while on bed B, the action-inducing sound is repeatedly played.

[0095] The restart condition may be a condition that is satisfied when only one of the following is satisfied: after the action-inducing sound playback process is stopped due to the stop condition being satisfied, the snooze time Tn has elapsed, or the non-operating time during which the determination unit 333 determines that the operating condition is not satisfied reaches the pause determination time Tm. For example, if 10 minutes have passed since the action-inducing sound playback process was stopped, the action-inducing sound playback process is resumed regardless of whether the operating condition is satisfied.

[0096] After that, in this embodiment, from time t7 to time t 11 In this embodiment, the same operations as those from time t2 to time t6 are repeated until the determination unit 333 determines that the above-described leaving condition is satisfied.

[0097] Then, when the determination unit 333 determines that the exit condition is satisfied, the sound playback unit 334 stops the action-inducing sound playback process, the action sound playback process, or the background sound playback process if these processes are being executed. Furthermore, when the determination unit 333 determines that the exit condition is satisfied, the sound playback unit 334 does not resume the action-inducing sound playback process even if the resume condition is subsequently satisfied. Therefore, when the determination unit 333 determines that the exit condition is satisfied, the sound playback unit 334 does not execute the action-inducing sound playback process, the action sound playback process, or the background sound playback process until the time measured by the timing unit 331 reaches a time determined according to the alarm time. This makes it possible to completely stop the sound playback when the user gets out of bed. Particularly in this embodiment, since the background sound playback process is stopped when the determination unit 333 determines that the exit condition is satisfied, the user can be prompted to get out of bed.

[0098] Furthermore, when the determination unit 333 determines that the leaving condition is satisfied, the sound replay unit 334 executes a bed exit sound replay process that replays a bed exit sound that is different from the action-inducing sound, the action sound, and the background sound. Note that the bed exit sound replay process is executed only when it is determined that the leaving condition is satisfied. Therefore, the bed exit sound replay process is not executed unless the leaving condition is satisfied, even when, for example, the stop condition or the resume condition is satisfied. By replaying the bed exit sound only when the leaving condition is satisfied, the user can recognize that the action-inducing sound replay process and the like have been stopped and will not be executed in the future.

[0099] Furthermore, when the determination unit 333 determines that the leaving condition is satisfied, the counting unit 335 resets the operation time to zero. Alternatively, when it is determined that the leaving condition is satisfied, the counting process in the counting unit 335 may be terminated.

[0100] In the example shown in FIGS. 5 and 6, time t 12 At time t, the determination unit 333 determines that the departure condition is satisfied. 12 At time t 12 At this point, the background sound playback process is stopped, thereby stopping the playback of the background sound.

[0101] 8 is a time chart similar to FIG. 5 showing the volume of the entire sound reproduced by the sound reproduction device 1. In the example shown in FIG. 10 After the action sound playback process is started, the determination unit 333 determines that the withdrawal condition is satisfied before the action time counted by the count unit 335 reaches the sound stop time Ts.

[0102] As shown in FIG. 8, when the determination unit 333 determines that the withdrawal condition is satisfied during the execution of the action prompting sound playback process, the action sound playback process, and the background sound playback process (at time t 13 ), the sound reproducing unit 334 stops these processes. 13 In addition, the sound playback unit 334 stops playing the action prompt sound, the action sound, and the background sound at time t 13 In addition, in this embodiment, the bed exit sound reproducing process is executed at time t 13 At this time, the operation time counted by the counting unit 335 is reset to zero.

[0103] <Control flow> Next, the control flow will be described with reference to Figures 9 to 11. Figure 9 is a flowchart showing the flow of a playback process for playing back various sounds from the speaker 12. The illustrated playback process is executed by the processor 33 of the control unit 30 when the alarm time is set by the setting unit 336.

[0104] 9, when the playback process starts, first, the sound playback unit 334 determines whether the determination unit 333 has determined that the exit condition is satisfied (step S11). If it is determined in step S11 that the exit condition is satisfied, the sound playback unit 334 stops the background sound control process that controls the background sound playback process, the action prompting sound control process that controls the action prompting sound playback process, and the action sound control process that controls the action sound playback process. Therefore, if the background sound playback process, the action prompting sound playback process, or the action sound playback process is being executed, these playback processes are stopped. In addition, the sound playback unit 334 executes a bed exit sound playback process, thereby playing a bed exit sound (step S13), and the playback process is terminated.

[0105] If it is determined in step S11 that the withdrawal condition is not satisfied, the sound playback unit 334 executes background sound control processing (step S14). During the execution of the background sound control processing, when the time measured by the timer unit 331 reaches the set alarm time, the sound playback unit 334 starts the background sound playback processing and plays the background sound. Furthermore, during the execution of the background sound control processing, when the playback of the background sound starts, the sound playback unit 334 gradually increases the volume of the background sound in the order of a first volume v1 and a fourth volume v4. Furthermore, when the operation time counted by the count unit 335 increases from zero, the sound playback unit 334 decreases the volume to a second volume v2, and when the operation time reaches zero, increases the volume to a fourth volume v4. Furthermore, when a stop condition is satisfied, that is, when the operation time reaches a sound stop time Ts, the sound playback unit 334 decreases the volume of the background sound to the first volume v1. In addition, when the restart condition is satisfied after the stop condition is satisfied, the sound playback unit 334 increases the volume of the background sound again to the fourth volume v4.

[0106] Next, the sound playback unit 334 executes an action-inducing sound control process (step S15). During the execution of the action-inducing sound control process, when the time counted by the timer unit 331 reaches the time when the intro period has elapsed since the set alarm time, the sound playback unit 334 starts the action-inducing sound playback process and plays the action-inducing sound. During the execution of the action-inducing sound control process, when the playback of the action-inducing sound starts, the sound playback unit 334 increases the volume of the sound to a fifth volume v5. When the action time counted by the count unit 335 increases from zero, the sound playback unit 334 decreases the volume to a third volume v3, and when the action time reaches zero, increases the volume to a fifth volume v5. Furthermore, when a stop condition is satisfied, that is, when the action time reaches a sound stop time Ts, the sound playback unit 334 stops the action-inducing sound playback process. In addition, when the restart condition is satisfied after the stop condition is satisfied, the sound replay unit 334 restarts the action-guiding sound replay process and increases the volume of the sound again to the fifth volume level v5.

[0107] Next, the sound playback unit 334 executes action sound control processing (step S16). The action sound control processing will be described with reference to Fig. 10. Fig. 10 is a flowchart showing the flow of the action sound control processing. The illustrated action sound control processing is executed while step S16 is repeatedly passed through in the playback processing of Fig. 9 and until the action sound control processing is stopped in step S12.

[0108] 10, when the action sound control process is started, the sound replay unit 334 first determines whether or not the action sound replay process is currently in an executable period (step S21). In this embodiment, the action sound replay process is executed while the action prompting sound is being played, and therefore, when the action prompting sound replay process is being executed, it is determined that the action sound replay process is currently in an executable period.

[0109] If it is determined in step S21 that the action sound playback process is currently in an executable period, the sound playback unit 334 determines whether the determination unit 333 has determined that the operation conditions are satisfied (step S22). If it is determined in step S22 that the operation conditions are satisfied, and if the counting unit 335 has counted a non-operation time in step S27 (described later), the counting unit 335 resets the non-operation time to zero (step S23). Next, the counting unit 335 increments the counted operation time (step S24). Next, the sound playback unit 334 determines whether the operation time counted in step S24 is equal to or greater than a predetermined sound stop time Ts (step S25). If it is determined in step S25 that the operation 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.

[0110] On the other hand, if it is determined in step S25 that the action time is equal to or greater than the sound stop time Ts, both the action time and non-action time counted by the count unit 335 are reset to zero (step S27). Next, if an action sound playback process is being executed, the sound playback unit 334 stops the action sound playback process (step S28). Also, if it is determined in step S21 that the action sound playback process is not in an executable period, for example, if the action prompting sound playback process is not being executed, both the action time and non-action time are reset to zero (step S27), and the action sound playback process is stopped (step S28).

[0111] If it is determined in step S22 that the operation condition is not satisfied, the counting unit 335 increases the counted non-operating time (step S29). Next, the sound reproducing unit 334 determines whether the non-operating time counted in step S29 is equal to or greater than a predetermined reset time Tr (step S30). If it is determined in step S30 that the non-operating time is less than the reset time Tr, the sound reproducing unit 334 determines whether the operating time counted by the counting unit 335 is zero (step S31).

[0112] If it is determined in step S31 that the action time is not zero, that is, if the action sound playback process has been executed once since it was determined that the action sound playback process is in an executable period, the action sound playback process is executed (step S26. 5a ~t 5b , time t 5d ~t 5e On the other hand, if it is determined in step S31 that the action time is zero, that is, if the action sound playback process has not been executed even once since it was determined that the action sound playback process was in an executable period, both the action time and the non-action time are reset to zero (step S27), and the action sound playback process is stopped (step S28).

[0113] Next, the action sound reproduction process will be described with reference to Fig. 11. Fig. 11 is a flowchart showing the flow of the action sound reproduction process. The illustrated action sound reproduction process is executed while step S26 is repeatedly passed through in the action sound control process of Fig. 10.

[0114] 11, when the action sound playback process starts, the sound playback unit 334 first determines whether or not a request to stop the action sound playback process has been made (step S41). When the action sound playback process is stopped in step S28 of the action sound control process, the sound playback unit 334 determines that a request to stop the action sound playback process has been made. If it is determined in step S41 that a request to stop the action sound playback process has been made, the action sound playback process is terminated.

[0115] On the other hand, if it is determined in step S41 that a request to stop the action sound playback process has not been made, the sound playback unit 334 determines whether the action time counted in step S24 of the action sound control process is at a predetermined sound playback timing (step S42). The sound playback timing indicates the timing at which each action sound that is played multiple times during the action sound playback process is played. In this embodiment, the time interval between the playback timings of two consecutive action sounds (i.e., the action determination time between sounds) is different from each other. In particular, in this embodiment, as described above, the time interval between the playback timings of two consecutive action sounds becomes longer as the number of times the action sound has already been played increases.

[0116] If it is determined in step S42 that the action time is not the sound playback timing, step S41 is repeatedly executed. On the other hand, if it is determined in step S42 that the action time is the sound playback timing, the count unit 335 increments the count of the number of times the action sound has been played by one (step S43). Next, the sound playback unit 334 plays the action sound according to the number of times the action sound has been played counted in step S43 (step S44), and then step S41 is repeatedly executed.

[0117] <Modification> In the above embodiment, the sound playback is completely stopped when the determination unit 333 determines that the departure condition is satisfied. However, the sound playback may be completely stopped due to a factor other than the departure condition being satisfied. For example, the sound playback may be completely stopped when the user presses the operation unit 20 or when a certain time (e.g., one hour) has elapsed since the clock time reached the time determined by the alarm time.

[0118] In the above embodiment, the sound playback unit 334 plays the action prompting sound over the background sound. However, the sound playback unit 334 may stop playing the background sound when playing the action prompting sound. In this case, the sound playback unit 334 stops the background sound playback process when executing the action prompting sound playback process. Then, the sound playback unit 334 resumes the background sound playback process when the action prompting sound playback process is stopped, except when it is determined that the withdrawal condition is satisfied. Therefore, in the examples shown in FIGS. 5 and 6, the background sound playback process is stopped from time t2 to t6 and from time t7 to t 11 In this case, the background sound may be stopped from playing.

[0119] Additionally, in the above embodiment, the sound playback unit 334 plays the action sound superimposed on the action prompting sound and the background sound. However, in one modified example, the sound playback unit 334 may stop the playback of the action prompting sound and the background sound while the action sound is being played. In this case, both the action sound and the action prompting sound may be music, and the action sound may be music that is related to the music of the action prompting sound but different from the music of the action prompting sound, as described above.

[0120] Specifically, in this modification, the sound playback unit 334 stops the action prompting sound playback process and the background sound playback process when executing the action sound playback process. When the sound playback unit 334 stops the action sound playback process for a reason other than the stop condition being satisfied, the sound playback unit 334 resumes the action prompting sound playback process and the background sound playback process. Alternatively, the sound playback unit 334 may stop the action prompting sound playback process and the background sound playback process when playing an action sound (i.e., when playing each of the action sounds played multiple times during the action sound playback process). When the sound playback unit 334 stops the action sound playback for a reason other than the stop condition being satisfied, the sound playback unit 334 may resume the action prompting sound playback process and the background sound playback process.

[0121] In addition, either one of the action prompting sound replay process and the background sound replay process may not be executed. Therefore, in this case, when the measured time reaches the time determined according to the alarm time, only one of the action prompting sound replay process and the background sound replay process will be executed.

[0122] In the above embodiment, when the action sound playback process is stopped by the determination unit 333 determining that the operation conditions are satisfied, the action sound playback process is not executed for the snooze time Tn. However, in one modification, the action sound playback process may be executed before the snooze time Tn has elapsed. In other words, the action sound playback process may be executed when the action prompting sound playback process is not being executed.

[0123] Furthermore, when the sound playback unit 334 executes the action sound playback process when the action prompting sound playback process is not being executed, the sound playback unit 334 may play an action sound that is different from the action sound that is played when the action prompting sound playback process is being executed. In this case, the sound stop time Ts may be different from that when the action prompting sound playback process is being executed. In particular, the sound stop time Ts may be longer in this case than when the action prompting sound playback process is being executed. Alternatively, in this case, even if there is no sound stop time Ts and the determination unit 333 determines that the operation conditions are continuously satisfied, the action sound playback process may continue to be executed without being stopped.

[0124] Furthermore, in the above embodiment, the multiple different action sounds played during the action sound playback process are changed based on the operation time counted by the counting unit 335. However, in one variation, the action sound played during the action sound playback process may be changed according to the magnitude of the movement of the object detected by the non-contact sensor 21. For example, the greater the movement of the object detected by the non-contact sensor 21, the longer the length of the action sound, the louder the volume, or the more times the repeated sound is repeated. For example, if the action sound is a sound effect of winning coins in a given game, the greater the movement of the object detected by the non-contact sensor 21, the more times the sound effect of winning coins is repeated during playback of one action sound (the more coins are won).

[0125] In the above embodiment, whether or not the stop condition for stopping the action prompting sound playback process and the action sound playback process is satisfied is determined based only on the time during which the operation condition is satisfied. However, the stop condition may be satisfied earlier as the magnitude of the object movement detected by the non-contact sensor 21 increases.

[0126] In one modification, if it is determined that the condition for leaving the bed has not been met even after a predetermined grace period (e.g., 20 minutes) has elapsed since the measured time reached the time determined according to the alarm time, the sound reproducing unit 334 may execute a urging mode. The urging mode is a mode that more strongly urges the user to wake up and get out of bed than the normal mode until the grace period has elapsed.

[0127] In this modified example, in the urgent mode, action prompting sound playback processing, action sound playback processing, and background sound playback processing are performed in the same manner as in the normal mode. The action prompting sound, action sound, and background sound are different between the urgent mode and the normal mode. In the urgent mode, these sounds are, for example, more urgent than in the normal mode. Furthermore, the volume of these sounds in the urgent mode may be louder than in the normal mode. Furthermore, the snooze time Tn, pause determination time Tm, and reset time Tr in the urgent mode may be shorter than in the normal mode. Furthermore, the sound stop time Ts in the urgent mode may be longer than in the normal mode.

[0128] Furthermore, in one modified example, after it is determined that the leaving condition is satisfied and the bed leaving sound reproducing process is executed, the determination unit 333 may continue to determine whether or not the user has gone to bed. For example, after it is determined that the leaving condition is satisfied, the determination unit 333 continues to determine whether or not the user has gone to bed based on the movement of an object in a predetermined area in bed B that is smaller than bed B, for a predetermined re-entering-bed monitoring time.

[0129] In this modification, when the determination unit 333 determines that the user has gone back to bed after determining that the bed getting-out condition has been satisfied, the action-inducing sound replay process and the background sound replay process are resumed in the same manner as when the clocked time reaches the time determined according to the alarm time. Therefore, when the determination unit 333 determines that the user has gone back to bed after determining that the bed getting-out condition has been satisfied, the action-inducing sound replay process and the background sound replay process are executed.

[0130] The sound reproducing unit 334 may execute the urging mode regardless of whether the bed getting-out condition has been satisfied. Therefore, even after the bed getting-out condition has been satisfied, if the action-inducing sound reproducing process or the background sound reproducing process is being executed when a predetermined grace period has elapsed since the measured time reached the time determined according to the alarm time, the sound reproducing unit 334 may execute the urging mode.
