Hereinafter, specific embodiments will be described with reference to the drawings.

[First Embodiment]
(Configuration of the first embodiment)
The configuration of the first embodiment will be described in detail with reference to FIGS. FIG. 1 is a block diagram showing a configuration of a portable terminal (electronic device) 1 according to the first embodiment. Further, the earphone 2 shown in FIG. 1 is a cordless (wireless) type earphone having a speaker 3 and a built-in microphone 4. The wireless communication unit 19 of the portable terminal 1 exchanges data with the wireless communication unit 39 of the earphone 2 by wireless communication. The wireless communication unit 19 of the mobile terminal 1 and the wireless communication unit 39 of the earphone 2 are preferably, for example, Bluetooth, which is a short-range wireless communication standard.

Next, FIG. 2 shows a state in which the user 5 is sleeping with the earphone 2 attached to the ear 6. The mobile terminal 1 has a “wake-up function” that wakes up the user 5 by reproducing the wake-up sound transmitted by wireless communication on the speaker 3 of the earphone 2. The earphone 2 is preferably a cordless type that does not easily come off the ear 6 during sleep, but is not limited thereto, and may be a cord type.

Next, returning to FIG. 1, the configuration of the mobile terminal 1 will be described in detail. FIG. 1 shows a portion related to the alarm function among various functions of the portable terminal 1. As shown in FIG. 1, the mobile terminal 1 includes a control unit 10, a storage unit 12, a display unit 17, an operation unit 18, a heart rate measurement unit 14, an alarm sound sending unit 16, a switch 20, a speaker 21, and a wireless communication unit. 19 is comprised.

First, the control unit 10 controls the operation of the entire mobile terminal 1 by a CPU (Central Processing Unit) (not shown). A program that operates in the control unit 10 is stored in the storage unit 12 in advance, and is called and executed by the CPU of the control unit 10. The sleep determination unit 22 and the alarm sound control unit 23 of the control unit 10 illustrated in FIG. 1 are programs that operate on the CPU of the control unit 10, respectively. Details of processing contents of the sleep determination unit 22 and the alarm sound control unit 23 will be described later.

The storage unit 12 includes a ROM (Read Only Memory) for storing a program and a RAM for storing data necessary for the operation of the program. The storage unit 12 stores an alarm sound source 27. Here, the wake-up sound source 27 includes one written in advance on the portable terminal 1, one downloaded by the user 5 via the Internet, one written via a recording medium, and the like. Further, the alarm sound source 27 may be anything that wakes up the user 5, and may be an alarm sound source or a music file.

Further, the case where the mobile terminal 1 is a smartphone as shown in FIG. 2, the display unit 17 is configured by a liquid crystal panel method, and the operation unit 18 is configured by a touch panel method is illustrated. However, the present invention is not limited to this, and any portable terminal that can use the earphone 2 provided with the built-in microphone 4 is applicable.

Next, the heart rate measuring unit 14 includes a heart rate calculating unit 32. The heartbeat sound collected by the built-in microphone 4 of the earphone 2 is amplified by the amplifier 30 and then converted into a digital signal by the A / D converter 31. The heart rate calculating unit 32 of the heart rate measuring unit 14 inputs the digital signal converted by the A / D converter 31 and calculates the heart rate C2. Here, the heart rate calculation unit 32 is configured by a program operated by the CPU. In FIG. 1, the heart rate calculation unit 32 is assumed to operate with a CPU (not shown) included in the heart rate measurement unit 14, but may be configured to operate with a CPU included in the control unit 10.

Since the portable terminal 1 has a function of sending the voice during a call collected by the built-in microphone 4 when the earphone 2 is attached to the other party, the amplifier 30 and the A / D converter 31 in FIG. It can be shared by the built-in amplifier and A / D converter. That is, when adding a heart rate measurement function in the portable terminal 1, there is no need to newly provide a heartbeat sound sensor or circuit (amplifier, A / D converter, etc.).

Next, the alarm sound sending unit 16 includes a D / A converter 34 and an amplifier 33. The alarm sound source 27 supplied from the storage unit 12 is converted into an analog signal by the D / A converter 34 and then amplified by the amplifier 33. Here, the amplifier 33 is a variable gain amplifier, and the gain of the amplifier 33 is controlled according to the volume setting VOL set by the user 5.

The volume setting VOL is set by the user 5 through the operation unit 18 and stored in the user wake-up setting information 28 in the storage unit 12. The user wake-up setting information 28 in the storage unit 12 stores the sound source information of the wake-up sound, the wake-up setting time, and the like in addition to the volume of the wake-up sound. Details of the user wake-up setting information 28 will be described later.

In FIG. 1, when the mobile terminal 1 and the earphone 2 are wirelessly connected, the input terminal of the switch 20 is controlled to be electrically connected to the first output terminal 41. As a result, the alarm sound transmitted from the alarm sound transmitter 16 is output to the speaker 3 of the earphone 2. On the other hand, when the mobile terminal 1 is not connected to any earphone, the input terminal of the switch 20 is controlled to be electrically connected to the second output terminal 42. As a result, the alarm sound transmitted by the alarm sound transmitter 16 is output to the speaker 21 built in the portable terminal 1.

(Operation of the first embodiment)
Next, the operation of the first embodiment will be described in detail with reference to FIG. FIG. 3 is a flowchart showing the operation of the alarm control method according to the first embodiment. Also, FIG. 1 will be referred to as appropriate when each step of FIG. 3 is described.

In FIG. 3, first, the alarm sound control unit 23 of the control unit 10 reads the user wake-up setting information 28 stored in the storage unit 12.

FIGS. 5A and 5B show examples of user wake-up setting information 28 in two different cases. As shown in FIGS. 5A and 5B, the user wake-up setting information 28 includes the alarm setting time, the alarm sound source information, and the volume of the alarm sound. For example, the setting example in FIG. 5A shows that the alarm setting time is set to 7:15, the alarm sound source information is set to “alarm sound 1”, and the alarm sound volume is set to 5. As described above, the user wake-up setting information 28 can be set by the user 5 using the operation unit 18. In the following description of the operation, it is assumed that the setting is as shown in FIG. The alarm sound control unit 23 sets a volume setting VOL corresponding to the alarm sound volume 5 in the alarm sound sending unit 16 in advance. Also, the alarm sound source 27 corresponding to “alarm sound 1” is selected.

After the user wake-up setting information 28 is set by the operation unit 18, the user 5 wears the earphone 2 having the built-in microphone 4 on the ear 6 as shown in FIG. Not shown).

Thereafter, the heart rate calculation unit 32 of the heart rate measurement unit 14 acquires the heart rate sound collected by the built-in microphone 4 from the ear 6, and the heart rate C2 is measured based on the acquired heart rate sound (S11). As a method of calculating the heart rate C2 in the heart rate calculation unit 32, a known method disclosed in Patent Document 2 or the like can be applied. FIG. 4 shows an example of measurement data of the heart rate C2 of the user 5 calculated by the heart rate calculation unit 32.

As shown in FIG. 4, when the user 5 is sleeping, the non-REM sleep appears first when entering the sleep state, and thereafter, the non-REM sleep and the REM sleep are repeated four or five times by the morning. Here, REM sleep is a shallow sleep state, where the body is sleeping but the brain is active. On the other hand, non-REM sleep is a state in which sleep is deep and the brain is resting but the metabolism of the body is promoted, and the heart rate becomes very gentle. Referring to FIG. 4, it can be seen that the heart rate is low during non-REM sleep, and the heart rate is higher during REM sleep than during non-REM sleep. In general, it is said that good awakening can be obtained by taking a sufficient amount of non-REM sleep, recovering the body, and waking up at the timing of REM sleep, which is shallow.

In FIG. 4, the non-REM sleep stage is repeated for 60 minutes and the REM sleep stage is repeated for 30 minutes, and an increase in heart rate in the REM sleep stage can be confirmed.

Next, returning to FIG. 3, the sleep determination unit 22 of the control unit 10 is based on the heart rate C2 of the user 5 measured by the heart rate measurement unit 14, and the sleep stage of the user 5 is a REM sleep stage or a non-REM sleep stage. It is determined which one (S12). The algorithm of the sleep determination unit 22 may be, for example, a period in which the heart rate C2 is low as a non-REM sleep stage and a REM sleep stage in other periods. However, as shown in FIG. 4, since the heart rate measurement value C2 includes impulse-like data, the above determination is made after performing preprocessing by a median filter, a smoothing filter, or the like in order to remove the influence. It is better to go. The sleep stage C3 determined by the sleep determination unit 22 is output to the alarm control unit 23.

When it is determined in step S12 that the sleep stage C3 is the non-REM sleep stage, the process returns to step S11 because it is a timing at which good awakening cannot be obtained. On the other hand, when it is determined that the sleep stage C3 is the REM sleep stage, it is determined whether or not it is time to wake up the user 5 in the current REM sleep stage by the following steps S13 to S15. That is, it is necessary to set the timing of the wake-up sound at the time before the wake-up setting time of the user wake-up setting information 28 and the REM sleep stage, but in order to make the sleep time of the user 5 as long as possible, If the next REM sleep stage comes by the time, wait until that time.

First, in step S13 of FIG. 3, the start time of the next REM sleep stage (the current REM sleep stage and the subsequent REM sleep stage after the non-REM sleep stage) is predicted (S13). Here, each period of the REM sleep stage and the non-REM sleep stage uses general values, or if the REM sleep stage and the non-REM sleep stage have been passed by that time, the values of those periods should be used. Good.

Next, in FIG. 3, the start time of the next REM sleep stage is compared with the wake-up setting time (S14). If the next REM sleep stage start time> wake-up set time (Yes in S14), the next time the REM sleep stage is entered again, the wake-up set time will be passed, so the current timing of sending out the wake-up sound (S15). Then, control is performed so that the alarm sound is transmitted to the earphone 2 at the timing of the alarm sound (S16). Specifically, the alarm sound control unit 23 performs control to send an alarm sound by sending an alarm control signal C1 including an instruction to send an alarm sound to the alarm sound transmitter 16. Then, after step S <b> 16, the user 5 wakes up by the wake-up sound and touches the operation unit 18 of the mobile terminal 1 to stop the wake-up sound.

On the other hand, if the start time of the next REM sleep stage ≦ the wake-up time (No in S14), it is determined that it is better to wait for the next REM sleep stage again, and the process returns to step S11.

The above is the basic operation of the alarm sound control of the first embodiment, but the above operation can be variously changed and adjusted. For example, in step S15, the timing at which a predetermined time has elapsed since the transition to the REM sleep stage may be used as the alarm sound transmission timing.

If the earphone 2 is removed from the ear 6 of the user 5 during sleep, the heart rate measurement unit 14 detects that the microphone 4 has stopped collecting heartbeat sounds and determines that the earphone 2 has been removed. In that case, an alarm sound is output from the speaker 21 of the portable terminal 1 by connecting the input side connection terminal of the switch 20 to the second output terminal 42. Further, since the user's sleep stage cannot be determined when the earphone 2 is detached, the timing of the alarm sound is set to the alarm setting time.

Moreover, after the user 5 performs an operation to stop the alarm sound after step S16, the sleep determination unit 22 can determine whether the user 5 has fallen asleep twice. Specifically, when the user 5 has slept twice, the heart rate C2 does not increase to the heart rate at the time of awakening, so it can be determined that he slept twice. In that case, the alarm sound is transmitted again.

Further, as shown in FIG. 5B, the timing of the wake-up sound may be determined based only on the sleep stage of the user 5 without setting the wake-up setting time of the user wake-up setting information 28. When the wake-up time is not set as described above, instead of steps S13 and S14 in FIG. 3, the timing of the wake-up sound in the REM sleep stage after securing an appropriate sleep time (for example, about 7 hours). Set.

As described above, according to the portable terminal (electronic device) 1 according to the first embodiment, the sleep stage of the user 5 with a simple configuration without newly providing a sensor and a circuit for measuring the heart rate. The mobile terminal (electronic device) 1 that can give awakening to the user 5 can be provided.

In addition, since the sleep determination unit 22 determines the sleep stage of the user 5 based on the heart rate C2, the timing of the wake-up sound can be set to the REM sleep stage of the user 5. Therefore, since the user 5 can be awakened to the REM sleep stage, the user 5 can be awakened comfortably.

Also, by setting the alarm sound source information and the volume of the alarm sound in the user wake-up setting information 28, it is possible to obtain an effect that the setting according to the preference of the user 5 can be made. A sound source that the user 5 feels comfortable with can be selected as the alarm sound source. Also, at bedtime, music that induces sleep may be played.

Also, since it is played back through the earphone 2 both when waking up and at bedtime, there is an effect that there is no worry of disturbing surrounding people.

Further, as described above, when the earphone 2 is removed from the ear 6 of the user 5, the alarm sound can be output from the speaker 21 built in the portable terminal 1.

[Second Embodiment]
Next, the second embodiment will be described in detail with reference to FIGS. FIG. 6 is a block diagram illustrating a configuration of the mobile terminal (electronic device) 8 according to the second embodiment. As can be seen by comparing FIG. 6 with FIG. 1 (first embodiment), the mobile terminal 8 of the second embodiment is configured to wake up the user instead of the user wake-up setting information 28 of the mobile terminal 1 of the first embodiment. An information database 29 is provided, and the control unit 10 further includes a user wake-up information database processing unit 24. Since the other points are the same as those in the first embodiment, the same reference numerals are assigned and duplicate descriptions are omitted.

FIG. 7 shows an example of the user wake-up information database 29. As shown in FIG. 7, the user wake-up information database 29 is a collection of wake-up sound generation information, and is recorded and managed by the user wake-up information database processing unit 24 of the control unit 10. In the user wake-up information database 29, the wake-up setting time, the wake-up sound source information, and the wake-up sound volume data are the same as the user wake-up setting information 28 in the first embodiment.

Next, the following information is newly recorded in the user wake-up information database 29. First, after the user 5 is awakened by the wake-up sound, the user satisfaction is input in five stages from 1 to 5 by the operation unit 18 and the value is recorded. Recording the user satisfaction in this way can be used to optimize the awakening that the user 5 feels comfortable when setting the wake-up sound from the next time on. Specifically, instead of step S10 in the flowchart (FIG. 3) of the first embodiment, the wake-up sound control unit 23 refers to the user wake-up information database 29 and based on the user satisfaction up to the previous time, the wake-up sound source Alarm sound volume such as alarm sound volume is automatically set.

Also, in the user wake-up information database 29, the timing of the wake-up sound that actually generated the wake-up sound and the user sleep information determined by the sleep determination unit 22 are recorded. Examples of the user sleep information include times t1, t2,... At which the non-REM sleep stage and the REM sleep stage shown in FIG. . . , T8 is recorded. The user 5 can read the user wake-up information database 29 from the operation unit 18 and display it on the display unit 17. Thereby, it is possible to analyze the state of one's sleep and awakening. For example, in FIG. Referring to the data 3, the user satisfaction level is the lowest value 1, but it can be analyzed that the timing of the alarm clock sounded at 6:50, which is much earlier than the alarm clock setting time 8:00. . And the user 5 knows the transition of his / her sleep stage by referring to the user sleep information at this time, so what time is the bedtime to wake up at the time close to the wake-up time at the time of REM sleep? Can know if is good.

As described above, according to the portable terminal (electronic device) 8 according to the second embodiment, in addition to the effects obtained in the first embodiment, the user satisfaction after being awakened by the wake-up sound is recorded. And since it was used for the setting of the wake-up sound after the next time, the effect that the setting of the wake-up sound which optimizes the satisfaction degree of the user 5 can be performed automatically is acquired.

In addition, the user 5 refers to the recorded user wake-up information database 29 and grasps the transition of his / her sleep stage, so that the effect of optimizing the bedtime for obtaining a pleasant awakening can be obtained. It is done.

[Third Embodiment]
Next, a third embodiment will be described in detail with reference to FIG. FIG. 8 is a block diagram showing a configuration of a mobile terminal (electronic device) 9 according to the third embodiment. The mobile terminal 9 according to the third embodiment is assumed to be used by a plurality of users. The portable terminal 9 includes a user authentication unit 40 in the operation unit 18 and user wake-up

information databases

29a and 29b for a plurality of users in the storage unit 12. Since the other points are the same as those of the second embodiment, the same reference numerals are given, and duplicate descriptions are omitted.

The user authentication unit 40 of the operation unit 18 requests the user to input a user ID and a password.
