  Hereinafter, an embodiment in which the present invention is applied to an ear-worn device 1 incorporating a pulse measurement function will be described in detail with reference to the drawings. However, what can apply this invention is not limited to this.

[First Embodiment]
[1.1 Configuration]
[1.1.1 External configuration]
[1.1.1 (a) Appearance]
FIG. 1 is a diagram showing an ear-mounted device 1 with a built-in pulse measurement function, where (a) is a front view of the ear-mounted device 1 and (b) is a perspective view of the ear-mounted device 1. is there. The direction in the description is the direction for the user wearing the ear-worn device 1. Specifically, the face side (left side of FIG. 1 (b)) when the ear-mounted device 1 is worn is the front, the occipital side (right side of FIG. 1 (b)) is the rear, the left ear side is the left, The right ear is right, the top is up, and the bottom is down. In addition, the direction in which the left and right arm portions 112R and 112L are close to each other, that is, the direction toward the center of the head is defined as the inner direction, and the opposite is defined as the outer direction.

  The ear-worn device 1 includes a main body unit 100, a right arm unit 112R, a left arm unit 112L, a right driver unit 110R and a left driver unit 110L that are speaker units, and a pulse sensor unit 106. . The right arm portion 112R is supported at the upper right end portion of the main body portion 100 so as to be urged inward. Further, the left arm portion 112L is supported so as to be urged inward in the upper left end portion of the main body portion 100. The main body 100 is provided with a display 102 and various switches.

  FIG. 2B shows an example of the display 102. The display 102 includes a time display area 102a for displaying the time during which the pulse is measured, an exercise purpose display area 102b for displaying the current exercise purpose, and a radio operation state display area 102c indicating ON / OFF of the radio power. And the area is configured.

  A right driver unit support portion 114R that supports the right driver unit 110R is provided at the tip of the right arm portion 112R. Further, a left driver unit support portion 114L that supports the left driver unit 110L is provided at the distal end portion of the left arm portion 112L. A pulse notification switch S1 is disposed on the right side surface of the right driver unit support portion 110R, and a radio channel selection switch S2 is disposed on the left side surface of the left driver unit support portion 110L.

  The pulse sensor unit 106 has a clip that can be clamped to the earlobe, which is a part of the auricle, and a sensor for optically detecting the pulse is disposed on the clamping surface. The pulse sensor unit 106 is electrically connected via a cable 108 from the left side surface of the main body unit 100. Further, when the user does not use the pulse sensor unit 106, the pulse sensor unit 106 is sandwiched and locked on the protrusion 122.

  In order to wear the ear-mounted device 1, the user holds and spreads the right arm portion 112R and the left arm portion 112L in a direction in which the right driver unit 110R and the left driver unit 110L are separated from each other. Then, the ear-mounted device 1 is moved so as to wrap around the head from the back head 140 side, and the right driver unit 110R is inserted into the ear canal of the right ear and the left driver unit 110L is inserted into the ear hole of the left ear, so that the ear is mounted. The mold apparatus 1 is installed.

  At this time, due to the urging force transmitted to the right driver unit 110R and the left driver unit 110L via the right arm portion 112R and the left arm portion 112L, the right driver unit 110R and the left driver unit 110L are directed in the ear canal. It is pressed (inward direction). Further, as shown in FIG. 2A, the back surface of the main body 100 (the front surface of the main body 100) is brought into contact with the lower part of the back head 140, and the posture of the main body 100 is maintained.

  With such an ear-mounted device 1, the following effects can be obtained. First, the right driver unit 110R is inserted into the right ear canal and the left driver unit 110L is inserted into the left ear canal, and is pressed toward the inner side of the head by the urging force transmitted through the right arm portion 112R and the left arm portion 112L. As a result, the right driver unit 110R and the left driver unit 110L are reliably inserted into the ear canal. For this reason, it becomes difficult for each driver unit to come off with respect to the movement of the head, and a stable wearing feeling can be obtained.

  In addition, a straight line connecting the right driver unit 110R inserted into the right ear canal and the left driver unit 110L inserted into the left ear canal can serve as a swing shaft for swinging the main body 100 in the vertical direction. A shift in the axial direction of the swing shaft of the ear-mounted device 1 is suppressed.

  Further, since the power source unit such as a battery and various control circuits are built in the main body unit 100, the main body unit 100 occupies most of the weight of the ear-worn device 1 and becomes a heavy object to some extent. Therefore, the main body 100 is brought into contact with the vicinity of the lower part of the back head 140 due to the relationship between its own weight and the swing shaft. Therefore, the ear-mounted device 1 is held in a stable posture in which the main body 100 is in contact with the vicinity of the lower part of the back of the head 140, and even if the user is exercising, the swinging of the swing shaft in the rotation direction is performed. Is suppressed.

  In addition, since there are three places of contact with the head, the left and right ear holes and the occipital region 140, a feeling of obstruction that covers the head like conventional headphones is reduced, and a comfortable wearing feeling is obtained. .

  The right arm portion 112R is pressed against the head from the outside of the right ear pinna and the left arm portion 112L is pressed against the head from the outside of the left ear pinna. Accordingly, the right arm 112R does not hang on the root of the right auricle and the left arm 112L does not hang on the root of the left auricle, so it is possible to wear glasses when the ear-worn device 1 is worn. it can.

  Further, the pulse sensor unit 106 connected to the left side surface of the main body unit 100 is locked by sandwiching the earlobe of the left ear. Accordingly, since the ear-worn device 1 is completely worn when worn on the user's head, the cable 108 is unlikely to hinder the user's movement.

  The pulse sensor unit 106 is sandwiched and locked in the left ear (left side), whereas the pulse notification switch S1 is disposed on the right driver unit support unit 114R (right side). Thereby, the influence of the operation on the right side of the ear-worn device 1 that is the operation of the pulse notification switch S1 for listening to the measurement result such as the pulse rate on the pulse detection of the left pulse sensor unit 106 can be reduced.

[1.1.1 (b) Various switches]
The ear-mounted device 1 is provided with various switches, and the function of the input unit 60 is realized. The main body 100 is provided with a mode setting switch S3, a pulse measurement switch S4, a radio switch S5, a power switch S6, and volume switches S7 and S8. The right driver unit support portion 114R is provided with a pulse notification switch S1, and the left driver unit support portion 114L is provided with a radio channel selection switch S2.

  When the power switch S <b> 6 is pressed, the ear-worn device 1 is turned on and can measure a pulse. Specifically, first, the mode setting switch S3 is pressed, and values such as age are set. Subsequently, when the pulse measurement switch S4 is pressed, the ear-mounted device 1 measures the pulse and starts counting the time during which the pulse is measured (hereinafter referred to as “pulse measurement time” as appropriate). If the pulse measurement switch S4 is pressed again during measurement of the pulse, the pulse measurement is temporarily stopped and the pulse measurement time count is also stopped. Further, by pressing the pulse measurement switch for a predetermined time (for example, “1 second”) or longer, the pulse measurement is stopped and the pulse measurement time is reset. In addition, when the pulse notification switch S1 is pressed during pulse measurement, the CPU 10 notifies the current pulse rate and the like by executing the interrupt notification program 214.

  This will be specifically described with reference to the state transition diagram of FIG. FIG. 12A is a diagram showing the state transition of the ear-mounted device 1 using the display 102. First, the ear-mounted device 1 is in the state (1) when the power is turned on. (1) indicates that the pulse measurement time is 0 seconds, and the pulse sensor is OFF. Here, when the pulse measurement switch S4 is pressed, the state changes to (2). (2) is a state where the stopwatch is operating and counting the pulse measurement time. At this time, the pulse sensor is ON.

  When the pulse measurement switch S4 is pressed in the state (2), the state transitions to the state (3). (3) is a state in which the counting of the pulse measurement time is temporarily stopped. At this time, the pulse sensor is OFF. Here, when the pulse measurement switch S4 is pressed, the state transitions to the state (2) again.

  If the S4 switch is held down (long pressed) in the state (2) or (3), the state transitions to the state (1), the pulse measurement time is reset, and the pulse sensor is turned off.

  The radio switch S5 is a switch for operating the radio function. Here, an outline of the radio function will be briefly described. First, when the radio switch S5 is pressed by the user, the ear-worn device 1 turns on the radio function and outputs a broadcast of the selected reception frequency from the left driver unit 110L and the right driver unit 110R. When the volume switches S7 and S8 are pressed, the volume is adjusted. Further, when the radio channel selection switch S2 is pressed, another reception frequency is selected and the received broadcast is output from the left driver unit 110L and the right driver unit 110R.

[1.1.2 Internal configuration]
Here, the ear-mounted device 1 incorporating the pulse measurement function will be described. FIG. 3 is a block diagram of the ear-mounted device 1. As shown in the figure, the ear-worn device 1 includes a CPU (Central Processing Unit) 10, a ROM (Read Only Memory) 20, a RAM (Random Access Memory) 30, a pulse sensor unit 106, and a radio receiving circuit. Unit 50, input unit 60, display unit 70, sound output unit 80, and bus 90.

[1.1.3 ROM]
The ROM 20 is a read-only memory that stores an initial program for performing various initial settings, hardware inspections, loading of necessary programs, and the like. The CPU 10 sets the operating environment of the ear-worn device 1 by executing this initial program when the ear-worn device 1 is powered on.

  The ROM 20 stores various programs related to the operation of the ear-worn device 1 such as radio reception processing, various setting processes, and various communication processes, and programs for realizing various functions of the ear-worn device 1. In addition, the exercise purpose table 202, the advice voice storage area 204, the numerical voice storage area 206, the device control program 208, the first pulse measurement program 210, the voice notification program 212, and the interrupt notification program 214 are provided. Store.

  The exercise purpose table 202 is a table that stores parameters related to “exercise purpose” indicating the operation mode of the ear-worn device 1. As shown in FIG. 4A, the exercise purpose table 202 is associated with the exercise purpose (for example, “fat burning”), the exercise intensity range (for example, “35 to 55”), and the display unit 70. A lighting mark to be displayed (for example, “BURNING”) is stored.

  Here, the exercise intensity refers to the pulse rate per minute of the user when exercising (hereinafter, referred to as “exercise pulse rate” as appropriate) according to the calculation formula of FIG. What percentage of the difference between the user's maximum pulse rate and the resting pulse rate is the difference between the user's pulse rate per minute when resting (hereinafter referred to as “resting pulse rate” as appropriate) It is a value that represents.

  The advice voice storage area 204 is an area where the CPU 10 stores voice data when the advice is notified by voice. FIG. 4B is a diagram for explaining the data configuration of the advice voice storage area 204. The advice voice storage area 204 stores voice data for notifying “Above target pulse rate”, for example. Then, for example, when the condition “when the measured pulse rate exceeds the set range” is met, the CPU 10 reads the audio data “Above target pulse rate” and repeats “2” times to output the sound (notification). To do.

  The numerical voice storage area 206 is an area for storing voice data corresponding to a numerical value used when notifying the pulse rate in the interrupt notification process. For example, audio data “one” corresponding to “1”, audio data “fifty” corresponding to “50”, and the like are stored. Then, when “51” is notified, the CPU 10 notifies the pulse rate by continuously outputting “fifty” and “one”.

[1.1.4 RAM]
The RAM 30 is a memory that can be written at any time to temporarily hold various programs executed by the CPU 10, data related to the execution of these programs, and the like. In the present embodiment, areas of a pulse cycle accumulation storage area 302, a pulse rate accumulation storage area 304, personal data 306, and setting range data 308 are secured.

  The pulse cycle accumulation storage area 302 is a storage area for accumulating and storing the time required for one pulse (hereinafter referred to as “pulse time” as appropriate) for the pulse measured by the pulse sensor unit 106. For example, when the pulse time is measured as “400 ms”, the CPU 10 stores “400 ms” in the pulse rate accumulation storage area 304.

  The pulse rate accumulation storage area 304 is an area for accumulating and storing the calculated pulse rate per minute. As shown in FIG. 5 (a), the pulse rate storage area 304 accumulates the pulse rate per minute calculated from the measured pulse (hereinafter referred to as “measured pulse rate” as appropriate) every minute. To remember. Here, the calculation method of the pulse rate per minute is demonstrated using FIG.

  FIG. 6A is a diagram for explaining a pulse rate calculation method. In FIG. 6A, one pulse (beat) is represented by a pulse wave waveform for convenience. In addition, pulse times for one pulse (heartbeat) are represented as “pt1”, “pt2”, and the like, respectively. Also, in order to calculate the pulse rate, the first time (initial value) uses the pulse time for eight times from “pt1” to “pt8”, and “pt2” to “pt9” to calculate the second time It represents using the pulse time for 8 times until “. Here, for convenience, the pulse rate is illustrated as being calculated for each pulse, but in the present embodiment, the pulse rate is calculated at one minute intervals.

  The CPU 10 accumulates and stores the pulse time of the pulse measured by the pulse sensor unit 106 in the pulse cycle accumulation storage area 302 as needed. Then, the CPU 10 extracts eight times (“pt1”, “pt2”,..., “Pt8”) out of the pulse times stored in the pulse cycle accumulation storage area 302. Subsequently, the CPU 10 calculates the sum of the remaining eight times of the extracted eight pulse times, excluding the two from the maximum and the two from the minimum, and divides by 4 to calculate the pulse. An average of time (hereinafter, referred to as “average pulse time” as appropriate) is calculated (calculation formula of FIG. 6B). Then, the first pulse rate per minute is calculated by dividing 60 by the average pulse time. This is the first calculation method.

  From the second time on, the pulse rate is calculated as follows. That is, for example, when calculating the second pulse rate based on eight pulse times from “pt2” to “pt9”, a maximum of two and a minimum of two of the eight pulse times are calculated. The average pulse time of the four pulse times excluding is calculated. Then, 60 is calculated by calculating the sum of the calculated second average pulse time and the average pulse time calculated the previous time (first time) multiplied by 3 as a weight, and dividing by the value divided by 4 The second pulse rate is calculated (calculation formula in FIG. 6C).

  Similarly, for the third and subsequent times, the pulse rate can be calculated by calculating based on the calculation formula of FIG. Although the timing for calculating the pulse rate is described as being calculated every minute in the present embodiment, the present invention is not limited to this. For example, it is calculated every five minutes or constantly calculated. It's also good. In addition, since the normal pulse rate does not cause sudden fluctuations, if it is measured every minute, the processing load on the CPU 10 is reduced and the battery driving time is lengthened compared to the case of constant calculation. Is possible.

  The personal data 306 is stored about user information. As shown in FIG. 5B, the personal data 306 includes an age (for example, “30”), a resting pulse rate (for example, “60”), and an operation mode (for example, “fat burning”). include. These pieces of information are input by the user.

  The setting range data 308 is data for storing, as a setting range, the range of the pulse rate during exercise with respect to the range of exercise intensity appropriate for the exercise purpose. As shown in FIG. 5C, the setting range data 308 stores an upper limit value (eg, “131”) and a lower limit value (eg, “105”) of the pulse rate during exercise.

  Here, the calculation method of the setting range will be specifically described with reference to FIG. As shown in FIG. 7A, the maximum pulse rate is 100% exercise intensity, and the resting pulse rate is 0% exercise intensity. Here, the maximum pulse rate is an upper limit value of the pulse rate that can be taken when the user exercises, and can be calculated by “220-age”. The resting pulse rate is a pulse rate value measured by the user in a resting state, and is a “resting pulse rate” stored in the personal data 306.

  FIG. 7B shows an expression for calculating exercise intensity. The exercise intensity is obtained by dividing a value obtained by subtracting the pulse rate at rest from the pulse rate during exercise by a value obtained by subtracting the pulse rate at rest from the maximum pulse rate, and a value (%) obtained by multiplying by 100 is the exercise intensity.

  FIG. 7C is an equation for obtaining the pulse rate during exercise with respect to the exercise intensity. In order to determine the pulse rate during exercise, the value obtained by subtracting the pulse rate at rest from the maximum pulse rate is multiplied by the exercise intensity and divided by 100. Then, the pulse rate during exercise can be calculated by adding the pulse rate during rest.

  For example, as shown in FIG. 5B, in the personal data 306, the age is “30”, the resting pulse rate is “60”, and the operation mode is “fat burning”. Calculate the setting range. First, the maximum pulse rate is “220−30 = 190”. Since the operation mode is “fat burning”, the exercise intensity range is “35 to 55”% from the exercise purpose table 202. First, the arterial pulse rate when the exercise intensity is “35”% is calculated as “(220−30) −60) × 35/100 + 60≈105”. Further, when the arterial pulse rate at which the exercise intensity is “55”% is calculated, “(220−30) −60) × 55/100 + 60≈131” is obtained. Accordingly, the setting range of the arterial pulse rate is stored in the setting range data 308 with the lower limit value being 105 and the upper limit value being 131.

[1.1.5 CPU]
The CPU 10 is a central processing unit that executes processing based on a predetermined program in accordance with an input instruction and transfers instructions and data to each functional unit. Specifically, the CPU 10 reads a program stored in the ROM 20 in response to an operation signal input from the input unit 60, and executes processing according to the program. Then, a display control signal is appropriately output to the display unit 70 to display the processing result.

  Furthermore, in the present embodiment, the CPU 10 executes a device control process (see FIG. 8) according to the device control program 208 of the ROM 20, and a first pulse measurement process (see FIG. 9) according to the first pulse measurement program 210. And a voice notification process (see FIG. 10) according to the voice notification program 212 is executed as a subroutine. Further, when the pulse notification switch S1 is pressed, the interrupt notification process (FIG. 12A) according to the interrupt notification program 214 is executed as the interrupt process.

  Specifically, when the power switch is pressed in the device control process, the CPU 10 executes an initial operation process and operates the ear-worn device 1. When the radio switch S5 is pressed, the CPU 10 receives a radio. Subsequently, when the personal data 306 is not stored or when the setting mode is turned on, the CPU 10 causes the user to input the personal data 306. Then, a setting range is calculated based on the input personal data 306 of the user and stored as setting range data 308. Then, when the pulse measurement switch S4 is pressed, the CPU 10 executes a first pulse measurement process. Subsequently, when the power switch S6 is pressed, the CPU 10 ends the device control process.

  In addition, each time the pulse is measured (detected) by the pulse sensor unit 106 in the first pulse measurement process, the CPU 10 measures the pulse time for the one pulse and accumulates it in the pulse cycle accumulation storage area 302. Remember me. Further, every time a predetermined time elapses from the previous measurement (specifically, every minute), the measured pulse rate is calculated based on the pulse time stored in the pulse cycle accumulation storage area 302. And it determines whether it is in the range of the arterial heart rate memorize | stored in the setting range data 308, and performs the audio | voice alerting | reporting process which performs the audio | voice alerting | reporting according to the determination result.

  In the voice notification process, when the radio is ON, the CPU 10 performs voice notification by gradually decreasing the volume output of the radio. Then, when the voice notification is finished, the radio volume output is gradually increased to output the same volume as the volume output before the voice notification.

  In addition, when the pulse notification switch S1 is pressed, the CPU 10 executes an interrupt notification process. In the interrupt notification process, the CPU 10 determines whether or not the measured pulse rate is included in the pulse rate notification range of 30 to 199 times. When the measured pulse rate is 30 to 199 times, it is further determined whether or not the radio is ON. When the radio is ON, the sound output is performed by gradually decreasing the volume output of the radio. Then, when the voice notification is finished, the radio volume output is gradually increased to output the same volume as the volume output before the voice notification.

[1.1.6 Pulse sensor section]
The pulse sensor unit 106 is a device for detecting and measuring a pulse (heartbeat) by measuring a blood flow state of the user. As shown in FIG. 1, when the clip is clamped to the user's ear, a pulse sensor provided in the clip detects the pulse by coming into contact with the user's ear. Here, the pulse sensor includes a light emitting element such as a light emitting diode and a light receiving element such as a phototransistor, and emits light from the light emitting element toward the inside (ear side). Is reflected by the abutting ear, and the reflected light is received by the light receiving element, thereby detecting a change in the concentration of hemoglobin in the blood sent into the blood vessel of the ear according to the heartbeat. The CPU 10 measures (calculates) the pulse time based on the detection signal of the pulse sensor unit 106.
Note that light emitted from the light emitting element toward the inner side (ear side) may be transmitted through the abutting ear, and the transmitted light may be received by the light receiving element.

[1.1.7 Radio receiver]
The radio receiving circuit unit 50 is a circuit unit that outputs audio data of broadcast contents by receiving and demodulating radio waves transmitted from a broadcasting station. The CPU 10 receives the radio wave of the broadcasting station (frequency) set by the user and demodulates it as an audio signal. The detailed technical contents are omitted because they are publicly known.

[1.1.8 Input / output section]
The input unit 60 is an input device provided with switches (switches) necessary for input of numerical values and the like and function selection, and outputs a signal of a pressed switch to the CPU 10. A control command input means for instructing execution of processing or the like is realized by input of a switch in the input unit 60. The input unit 60 corresponds to various switches including the power switch S6 shown in FIG.

  The display unit 70 displays various screens based on a display signal output from the CPU 10, and is configured by an LCD (Liquid Crystal Display) or the like. The display unit 70 corresponds to the display 102 shown in FIG.

[1.2 Operation]
[1.2.1 Device control processing]
First, device control processing will be described. FIG. 8 is a flowchart for explaining the operation of the ear-worn device 1 according to the device control process. This device control process is a process realized by the CPU 10 executing the device control program 208 stored in the ROM 20.

  First, when the power switch S6 of the ear-worn device 1 is pressed (step A10; Yes), the CPU 10 executes an initial operation process such as initializing various variables (step A12).

  Next, when the radio switch S5 is pressed (step A14; Yes), the CPU 10 receives and demodulates the radio broadcast selected by the user via the radio reception circuit unit 50, and outputs it from the sound output unit 80. (Step A16).

  Next, the CPU 10 determines whether or not a setting value is stored in the personal data 306 (step A18). Here, when the setting value is not stored in the personal data 306 (step A18; No), the CPU 10 causes the user to input the age, the resting pulse rate, and the operation mode in the personal data 306, and the personal data. It memorize | stores in 306 (step A22). Then, the CPU 10 calculates the pulse setting range for the exercise intensity from the value stored in the personal data 306, and stores it in the setting range data 308 (step A24).

  Here, when the setting value is stored in the personal data 306 (step A18; Yes), it is determined whether or not the setting mode is to be turned on by pressing the mode setting switch S3 by the user (step S18). Step A20). When the setting mode is turned on by the user (step A20; Yes), the CPU 10 stores the setting value in the personal data 306 instructed / input by the user (steps A22, A24).

  Next, when the pulse measurement switch S4 is pressed (step A26; Yes), the CPU 10 executes a first pulse measurement process (step A28). Then, when the power switch S6 is pressed, the CPU 10 stops the operation of the ear-worn device 1 (step A30).

[1.2.2 First pulse measurement process]
Next, the first pulse measurement process will be described. FIG. 9 is a flowchart for explaining the operation of the ear-worn device 1 according to the first pulse measurement process. This first pulse measurement process is a process realized by the CPU 10 executing the first pulse measurement program 210 stored in the ROM 20, and is executed in step A28 of the device control process.

First, the CPU 10 measures the time (pulse time) for one pulse measured (detected) by the pulse sensor unit 106 (step B20). If the pulse time has not been measured for a certain time (step B22; Yes), the CPU 10 reports an error and ends the process (step B28). For example, when the pulse measurement time is not measured for 2 minutes, a notification sound “error” is output from the sound output unit 80 to inform the user that the pulse time has not been measured (no pulse is detected). Inform.
Here, for example, when a phenomenon in which the pulse measurement time is not measured for 2 minutes occurs twice, a notification sound “error” may be output from the sound output unit 80.

  Then, when the user's pulse time is measured (step B22; Yes), the CPU 10 determines whether or not a predetermined time has elapsed since the previous measurement (step B23). Here, when the predetermined time has not elapsed (step B23; No), the CPU 10 executes the process again from step B20. On the other hand, when the predetermined time has elapsed (step B23; Yes), the CPU 10 calculates the pulse rate per minute and stores it in the pulse rate storage area 304 (step B24). Subsequently, the CPU 10 compares the measured pulse rate with the pulse rate setting range stored in the setting range data 308 (step B26). If it is less than the lower limit value stored in the setting range data 308 (step B30; Yes), it is determined whether or not the pulse rate measured so far has entered the setting range (step B36). ). Specifically, it is determined whether or not the value stored in the pulse rate accumulation storage area 304 is included between the lower limit value and the upper limit value of the setting range data 308. If at least one data within the set range exists in the pulse rate stored in the pulse rate accumulation storage area 304 (step B36; Yes), the voice notification process is executed (step S36). B38).

  When the end is selected by the user (step B40), the CPU 10 ends the first pulse measurement process and returns control to the device control process.

[1.2.3 Voice notification processing]
Next, the voice notification process will be described. FIG. 10 is a flowchart for explaining the operation of the ear-worn device 1 according to the voice notification process. This voice notification process is a process realized by the CPU 10 executing the voice notification program 212 stored in the ROM 20, and is executed in step B38 of the first pulse measurement process.

  First, the CPU 10 determines whether or not the radio is ON (step C10). If the radio is ON (step C10; Yes), the CPU 10 executes a fade-out process (step C12). And CPU10 performs audio | voice alerting | reporting (step C14), and after audio | voice alerting | reporting is completed, it performs a fade-in process and outputs the audio | voice of a radio with the audio | voice output level before audio | voice alerting | reporting (step C16). On the other hand, when the radio is OFF (step C10; No), the CPU 10 performs voice notification (step C18).

  Here, the fade-out process means that the output level (volume) of the volume is gradually reduced from the output level of the current volume. The fade-in process means increasing the volume output level step by step. Specifically, there are 10 levels from “0” at which no sound is output, to “9”, which is the maximum output volume, as the output level of the volume. Then, when the fade-out process is performed when the current volume output level is “5”, the CPU 10 gradually decreases from “5” to “0”. When the fade-in process is performed, the CPU 10 gradually increases from “0” to “5”.

  The first pulse measurement process will be specifically described with reference to FIG. FIG. 12B is a graph showing the transition of the pulse rate, in which the horizontal axis represents time (unit: minutes) and the vertical axis represents the measured pulse rate (unit: bps: beats per minute). Also, dotted lines are drawn at the positions of the upper limit value “131” bpm and the lower limit value “105” bpm of the setting range stored in the setting range data 308.

  First, the measured pulse rate of “after 1 minute” and “after 2 minutes” is less than the set range (less than the lower limit value), but has never entered the set range in the past (Step B30; Yes → Step B36; No ). Therefore, the CPU 10 does not perform voice notification. Next, the measured pulse rate of “after 3 minutes” is within the set range, and the previously measured pulse rate of “after 2 minutes” is not within the set range (Step B30; No → Step B32; No → Step) B34; No). Therefore, the CPU 10 performs voice notification. Here, referring to FIG. 4 (b), “Target pulse rate achieved” is read as voice data and notified from the sound output unit 80 because the condition “when the measured pulse rate falls within the set range” is met. . Next, the measured pulse rate of “after 4 minutes” is within the set range, and the previously measured pulse rate of “after 3 minutes” is also within the set range (Step B30; No → Step B32; No → Step B34; Yes). Therefore, the CPU 10 does not perform voice notification.

  Further, the measured pulse rate “after 8 minutes” exceeds the upper limit value of the setting range (Step B30; No → Step B32; Yes). Therefore, voice notification is executed. Here, referring to FIG. 4B, since the condition “when the measured pulse rate exceeds the set range” is met, “Above target pulse rate” is read as audio data and output from the sound output unit 80. .

  Further, the measured pulse rate “after 15 minutes” is less than the lower limit value of the setting range. Moreover, since it has entered into the setting range in the past like the pulse rate “after 14 minutes”, the CPU 10 performs voice notification (step B30; Yes → step B36; Yes). Here, referring to FIG. 4B, since the condition “when the measured pulse rate is less than the set range” is met, “Below target pulse rate” is read as audio data and output from the sound output unit 80.

  In this way, the “Batsu” mark on the graph indicates the measurement time when voice advice is not performed, and the circle mark indicates “when the measured pulse rate exceeds the set range” and outputs voice advice “Above target pulse rate” Time, triangle mark indicates “when the measured pulse rate is within the setting range” and the voice advice “Target pulse rate achieved” is output, and square mark indicates “when the measured pulse rate is less than the set range” The measurement time for outputting the voice advice “Below target pulse rate” is shown.

[1.2.4 Interrupt notification process]
Next, the interrupt notification process will be described. FIG. 11A is a flowchart for explaining the operation of the ear-worn device 1 according to the interrupt notification process. This interrupt notification process is a process realized by the CPU 10 executing the interrupt notification program 214 stored in the ROM 20, and is executed as an interrupt process when the pulse notification switch S1 is pressed. Is.

  First, when the measured pulse rate is in the range of 30 to 199 bpm (step D10; Yes), the CPU 10 determines whether or not the radio is ON (step D12). When the radio is ON (step D12; Yes), the CPU 10 executes a fade-out process (step D14). Then, the CPU 10 executes the interrupt sound notification (step D16), and after the interrupt sound notification is completed, executes the fade-in process and outputs the radio sound at the sound output level before the interrupt sound notification ( Step D18). On the other hand, when the radio is OFF (step D12; No), the CPU 10 executes an interrupt voice notification (step D20).

  Here, the interrupt voice notification is a process of outputting the voice data read from the advice voice storage area 204 and notifying the measured pulse rate by voice as in the voice notification process.

  This will be specifically described with reference to FIGS. 11B and 11C. FIG. 11B is a diagram showing an example of the display screen W100, which shows that the pulse is being measured. When the pulse notification switch S1 is pressed in this state, the CPU 10 executes an interrupt notification process and notifies an interrupt sound. FIG.11 (c) is a figure which showed an example of the interruption sound. When the current measured pulse rate is “145” bpm, the voice data that reads “145” is read from the numerical voice storage area 206 and is output as “one forty five”, and then the voice data that matches the current conditions Is read from the advice voice storage area 204 and “Above target pulse rate” is output.

  Thus, according to the first embodiment, the pulse can be measured only by the ear-mounted device 1. In addition, by outputting the advice sound “Above target pulse rate” from the ear-mounted device 1, the user knows that the pulse rate has exceeded the set range, and the advice sound “Below target pulse rate” is provided. Is output, the user knows that the pulse rate is less than the set range. Furthermore, since the voice of advice “Target pulse rate achieved” is output, the user knows that the pulse rate has entered the set range, and thus the amount of exercise can be adjusted according to the notified voice. Further, even while listening to the radio, the advice sound or the sound volume of the radio is automatically adjusted when the pulse rate is output, so that the advice sound can be easily heard.

[Second Embodiment]
Next, a second embodiment to which the present invention is applied will be described. In the present embodiment, the interval of the pitch sound that is output according to the pulse rate during exercise (heart rate during exercise) is changed depending on whether it is within the set range, exceeds the set range, or does not meet the set range. , Helping to be an appropriate exercise.

[2.1 Configuration]
FIG. 13 is a block diagram of the ear-worn device 1 having a built-in pulse measurement function according to the second embodiment. As shown in FIG. 1, the ear-worn device 1 includes a CPU 10, a ROM 22, a RAM 32, a pulse sensor unit 106, a vibration detection unit 45, a radio reception circuit unit 50, an input unit 60, and a display unit 70. And a sound output unit 80 and a bus 90. The same components as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted. In each flowchart, steps having the same processing contents as those in the flowchart of the first embodiment are denoted by the same reference numerals, and different portions will be mainly described.

  First, the configuration of the ROM 22 will be described. As shown in FIG. 13, the ROM 22 includes an exercise purpose table 202, an advice voice storage area 204, a numerical voice storage area 206, a device control program 208, an interrupt notification program 214, a pitch time table 220, A two-pulse measurement program 222, a first interval setting program 224, and a second interval setting program 226 are stored.

The pitch time table 220 is a table that stores an interval time (hereinafter referred to as “pitch sound interval time” as appropriate) when outputting a pitch sound. FIG. 14A shows an example of the data structure of the pitch time table. For example, a 400m seconds as pitch sound interval time is a time t _1, the t _b is stored as 500m sec as pitch sound interval time.

  The second pulse measurement program 222 is a program for realizing the second pulse measurement process in the present embodiment, and the second pulse measurement process is realized by the CPU 10 executing the second pulse measurement program 222. The First, every time a pulse is measured (detected) by the pulse sensor unit 106, the CPU 10 measures a pulse time for one pulse and cumulatively stores it in the pulse period accumulation region 302. Further, every time a predetermined time elapses from the previous measurement (specifically, every minute), the measured pulse rate is calculated based on the pulse time stored in the pulse cycle accumulation storage area 302. Then, the CPU 10 compares the pulse rate range stored in the setting range data 308 with the calculated measured pulse rate, and if the measured pulse rate is less than the set range, the first interval setting process is exceeded. When the second interval setting process is performed, a pitch sound is output based on the pitch interval data. If the measured pulse rate is within the set range for a predetermined time, the output of the pitch sound is stopped.

The first interval setting program 224 is a program for realizing the first interval setting process in the present embodiment, and the CPU 10 executes the first interval setting program 224, whereby the first interval setting process is realized. The The CPU 10 calculates the difference between the lower limit value of the setting range data 308 and the measured pulse rate. When the calculated difference is equal to or smaller than the threshold value of item B stored in the notification range setting data 320, the pitch interval time is set to t _b and is larger than the threshold value of item B and smaller than or equal to the threshold value of item A. In this case, the pitch interval time is set to t _a, and when it is larger than the threshold value of item A, the pitch interval time is set to t ₁ .

The second interval setting program 226 is a program for realizing the second interval setting process in the present embodiment, and the second interval setting process is realized by the CPU 10 executing the second interval setting program 226. The The CPU 10 calculates the difference between the upper limit value of the setting range data 308 and the measured pulse rate. When the calculated difference is equal to or smaller than the threshold value of item B stored in the notification range setting data 320, the pitch interval time is set to t _c and is larger than the threshold value of item B and smaller than or equal to the threshold value of item A. In this case, the pitch interval time is set to t _d, and when it is larger than the threshold value of item A, the pitch interval time is set to t ₀ .

  Next, the configuration of the RAM 32 will be described. As shown in FIG. 13, the RAM 32 includes a pulse cycle accumulation storage area 302, a pulse rate accumulation storage area 304, personal data 306, setting range data 308, notification range setting data 320, measurement pitch data 322, An area with the pitch interval data 324 is secured.

  The notification range setting data 320 is an area that stores a threshold for determining how far away from the upper limit value or the lower limit value of the setting range stored in the setting range data 308. As shown in FIG. 14B, the notification range setting data stores a threshold value for item A (eg, “30”) and a threshold value for item B (eg, “10”).

  The measured pitch data 322 is data storing the measured pitch sound interval time. CPU10 memorize | stores the pitch sound interval time in the case of the exercise | movement calculated in step E12 of the 2nd pulse measurement process as measurement pitch data 322.

  The pitch interval data 324 is data storing the pitch sound interval time. The CPU 10 outputs a pitch sound from the sound output unit 80 based on the pitch interval data 324.

  The vibration detection unit 45 is a functional unit that detects vibration when the user walks or runs, and includes an acceleration sensor or the like. The acceleration sensor may use any of known techniques such as those using a strain gauge and those using a piezoelectric element.

[2.2 Process flow]
[2.2.1 Second pulse measurement process]
Next, the operation of the ear-worn device 1 in the second embodiment will be described with reference to the drawings. FIG. 15 is a flowchart for explaining the operation of the ear-worn device 1 according to the second pulse measurement process. This second pulse measurement process is a process realized by the CPU 10 executing the second pulse measurement program 222 of the ROM 22, and is a process executed in step A28 of FIG. 8 as a subroutine of the device control program 208. .

  First, the CPU 10 calculates the current motion (for example, walking or running) pitch by the vibration detection unit 45 detecting the vibration of the user (step E10), and stores it in the measured pitch data 322 (step E12). . Here, as a method for calculating the motion pitch, for example, any number of known methods such as a method of detecting how many times vibration has occurred in 5 seconds and calculating the time required for one vibration is used. Just do it.

Further, Step E20 to Step E26 are the same processes as Step B20 to Step B26 of the first pulse measurement process of the first embodiment. In brief, the CPU 10 measures the pulse time measured (detected) by the pulse sensor unit 106. If the predetermined time has elapsed since the previous measurement, the CPU 10 calculates the pulse rate per minute and stores it in the pulse rate storage area 304.
Subsequently, the CPU 10 compares the measured pulse rate with the setting range data 308. The following description will be divided into three cases where the measured pulse rate is less than the lower limit value of the setting range data 308, exceeds the upper limit value, and is included in the setting range.

(1) When the measured pulse rate is less than the set range When the measured pulse rate is less than the lower limit value of the set range data 308 (step E30; Yes), the pulse rate accumulated and stored in the pulse rate accumulation storage area 304 Among these, it is determined whether or not there is a value not less than the lower limit value and not more than the upper limit value of the setting range data 308 (step E34).

  Here, if it is determined that the pulse rate accumulated and stored in the pulse rate accumulation storage area 304 contains a pulse rate not less than the lower limit value and not more than the upper limit value of the setting range data 308 (step E34; Yes). ), The first interval setting process is executed, and the pitch interval data 324 is set (step E36). Then, the CPU 10 outputs a pitch sound based on the pitch sound interval time set in the pitch interval data 324 (step E58).

  On the other hand, if it is determined that the pulse rate accumulated and stored in the pulse rate accumulation storage area 304 does not store a pulse rate not less than the lower limit value and not more than the upper limit value of the setting range data 308 (step E34; No). The pitch interval data 324 is set to infinity (step E35). Then, since the infinite time is set in the pitch interval data 324, the CPU 10 does not output the pitch sound (step E58).

(2) When the measured pulse rate exceeds the set range When the measured pulse rate is not less than the lower limit value of the set range data 308 (step E30; No) and exceeds the upper limit value of the set range data 308 (Step E32; Yes), the CPU 10 executes the second interval setting process to set the pitch interval data 324 (Step E38). Then, the CPU 10 outputs a pitch sound based on the pitch sound interval time set in the pitch interval data 324 (step E58).

(3) When the measured pulse rate is in the set range When the measured pulse rate is not less than the lower limit value and not more than the upper limit value of the set range data 308 (Step E30; No → Step B32; No) Then, it is determined whether or not the last measured pulse rate is not less than the lower limit value and not more than the upper limit value of the setting range data 308 (step E40).

  Here, when it is not less than the lower limit value and not more than the upper limit value of the setting range data 308 (step E40; Yes), the CPU 10 determines whether or not the timer is operating (step E42). If the timer is not operating (step E42; No), the CPU 10 starts the timer (step E44). When a predetermined time (for example, “2 minutes”) has elapsed (step E46; Yes), the CPU 10 outputs the pitch sound when the pitch sound is being output (step E48; Yes). Stop (step E50). If the predetermined time has not elapsed (step E46; No), the CPU 10 outputs a pitch sound based on the pitch sound interval time set in the pitch interval data 324 (step E58).

  On the other hand, when it is not included in the setting range data 308 from the lower limit value to the upper limit value (step E40; No), the CPU 10 stops the timer when the timer is operating (step E52), The timer value is reset (step E54). Then, the pitch sound interval time stored in the measured pitch data 322 is set in the pitch interval data 324 (step E56), and the pitch sound is output (step E58).

  Then, when the process end is selected, the CPU 10 ends the second pulse measurement process (step E60; Yes), and when the process end is not selected, the process proceeds to step E10 (step E60). No).

[2.2.2 First interval setting process]
Next, the first interval setting process will be described. FIG. 17 is a flowchart for explaining the operation of the ear-worn device 1 according to the first interval setting process. This first interval setting process is a process realized by the CPU 10 executing the first interval setting program 224 stored in the ROM 22, and is executed in step E36 of the second pulse measurement process.

First, the CPU 10 substitutes a value obtained by subtracting the measured pulse rate from the lower limit value of the setting range as a variable X (step F10). Then, in the case of subthreshold item B of X is stored in the broadcast range setting data 320 (step F12; Yes), CPU 10, from the pitch time table 220, reads out the time t _b (step F14). Then, the CPU 10 sets the time t _b in the pitch interval data 324 (step F16).

On the other hand, when X is larger than the threshold value of the item B stored in the notification range setting data 320 (step F12; No), the CPU 10 stores the item A in which X is stored in the notification range setting data 320. It is determined whether it is below the threshold value (step F18). Then, if X is less than or equal to the threshold value of the item A stored in the notification range setting data 320 (step F18; Yes), CPU 10, from the pitch time table 220, reads out the time t _a (step F20). Then, the CPU 10 sets _a time ta in the pitch interval data 324 (step F22).

Further, when X is larger than the threshold value of the item A (step F18; No), CPU 10, from the pitch time table 220, reads out the time t ₁ (step F20). Then, the CPU 10 sets time t ₁ in the pitch interval data 324 (step F22).

[2.2.3 Second interval setting process]
Next, the second interval setting process will be described. FIG. 18 is a flowchart for explaining the operation of the ear-worn device 1 according to the second interval setting process. This second interval setting process is a process realized by the CPU 10 executing the second interval setting program 226 stored in the ROM 22, and is executed in step E36 of the second pulse measurement process.

First, the CPU 10 substitutes the value obtained by subtracting the upper limit value of the setting range from the measured pulse rate as a variable X (step G10). Next, when X is equal to or smaller than the threshold value of the item B stored in the notification range setting data 320 (step G12; Yes), the CPU 10 reads the time t _c from the pitch time table 220 (step G14). Then, the CPU 10 sets time t _c in the pitch interval data 324 (step G16).

On the other hand, when X is larger than the threshold value of the item B stored in the notification range setting data 320 (step G12; No), the CPU 10 determines that the item A has X stored in the notification range setting data 320. It is determined whether it is below the threshold value (step G18). Then, if X is less than or equal to the threshold value of the item A stored in the notification range setting data 320 (step G18; Yes), CPU 10, from the pitch time table 220, reads out the time t _d (step G20). Then, the CPU 10 sets the time t _d in the pitch interval data 324 (step G22).

Further, when X is larger than the threshold value of the item A (step G18; No), CPU 10, from the pitch time table 220, reads out the time t ₀ (step G24). Then, the CPU 10 sets time t ₀ in the pitch interval data 324 (step G26).

[2.3 Example of operation]
Here, it demonstrates concretely using FIG. FIG. 19 is a graph showing the transition of the pulse rate, with the horizontal axis representing time (unit: minutes) and the vertical axis representing the measured pulse rate (unit: bpm). Further, the shaded portion indicates between the upper limit value “131” bpm and the lower limit value “105” bpm of the setting range stored in the setting range data 308.

  First, the measured pulse rates of “after 1 minute” and “after 2 minutes” are less than the set range, but have never entered the set range in the past (Step E30; Yes → Step E34; No). Therefore, the CPU 10 sets the pitch interval data 324 to infinity (step E35), so that no pitch sound is output (step E58). Next, the measured pulse rate of “after 3 minutes” is within the set range, and the previously measured pulse rate of “after 2 minutes” is not within the set range (Step E30; No → Step E32; No → Step) E40; No). Since the timer is not operating (step E52; No), the CPU 10 sets the pitch interval data 324 with the value of the measured pitch data 322 (step E56), and outputs a notification sound based on the set value. (Step E58).

  Next, the measured pulse rate of “after 4 minutes” is within the set range, and the previously measured pulse rate of “after 3 minutes” is also within the set range (Step E30; No → Step E32; No → Step E40; Yes). Since the timer is not operating (step E42; No), the CPU 10 starts the timer (step E44). Next, since “2 minutes” of the predetermined time has not elapsed (step E46; No), the CPU 10 outputs a pitch sound based on the pitch interval data 324 (step E58).

Next, the measured pulse rate “after 5 minutes” exceeds the upper limit of the set range (step E30; No → step E32; Yes). Therefore, the CPU 10 executes the second interval setting process. Here, since the difference between the measured pulse rate at “5 minutes later” and the upper limit value of the setting range data 308 is equal to or less than the threshold value of the item B (step G12; Yes), the CPU 10 determines the time from the pitch time table 220. t _c “700 ms” is read (step G14) and set in the pitch interval data 324 (step G16). Then, the CPU 10 outputs a pitch sound at a time “700 ms” interval set in the pitch interval data 324 (step E58).

Next, the measured pulse rate “after 6 minutes” also exceeds the upper limit of the setting range (step E30; No → step E32; Yes). Therefore, the CPU 10 executes the second interval setting process. Here, the difference between the measured pulse rate “after 6 minutes” and the upper limit value of the setting range data 308 is not included below the threshold value of the item B, but is below the threshold value of the item A (step G12; No (Step G18; Yes), the CPU 10 reads the time t _d “750 msec” from the pitch time table 220 (Step G20) and sets it in the pitch interval data 324 (Step G22). Then, the CPU 10 outputs a pitch sound at a time “750 msec” set in the pitch interval data 324 (step E58).

  Since the measured pulse rate “after 8 minutes” is included in the set range (step E30; No → Step E32; No → Step E40; No), the CPU 10 determines whether the timer is operating. Determine whether. Here, since the timer is operating from “after 4 minutes” (step E52; Yes), the timer is stopped and reset (step E54). Then, the CPU 10 reads the calculated pitch interval from the measured pitch data 322, and sets the read value in the pitch interval data 324 (step E56). Then, the CPU 10 outputs a pitch sound based on the pitch interval data 324 (step E58).

  Further, the measured pulse rate “after 9 minutes” is less than the lower limit value of the setting range data 308, and the pulse rate measured in the past may have been included in the setting range (step E30; Yes → step E34). ; Yes), the first interval setting process is executed (step E36).

Here, since the difference between the measured pulse rate at “9 minutes later” and the lower limit value of the setting range data 308 is equal to or less than the threshold value of the item B (step F12; Yes), the CPU 10 determines from the pitch time table 220. , Time t _b “500 ms” is read (step F14), and is set in the pitch interval data 324 (step F16). Then, the CPU 10 outputs a pitch sound at a time interval of “500 milliseconds” set in the pitch interval data 324 (step E58).

  As described above, according to the second embodiment, it is possible to measure the pulse only by wearing the ear-worn device, and further, the measured pulse so as to obtain an appropriate momentum according to the exercise purpose. A pitch sound can be output from a number.
