<Embodiment 1>
( Ear-mounted sound generator )
FIG. 1 is a perspective view of an ear-mounted sound generator according to Embodiment 1 in a mounted state. FIG. 2 is a perspective view of the ear-mounted sound generator . As shown in FIG. 1, earset sound generator 10 is an example of earset earset sound generating device, the main housing 11 is engaged to the ear is supported by the ear. The ear-mounted sound generator 10 has a disk-shaped head 12 in an ear cavity 1b surrounding the ear hole 1a in a state where the earlobe 1c is sandwiched between the main body casing 11 and the clip portion (13: FIG. 2). The main body housing 11 is held on the ear surface by fitting.

The clip part 13 can pinch the ear between the main body housing 11 in a state where the electronic buzzer element (62: FIG. 3) housed in the head part 12 is positioned in a recess around the ear hole. When the user wears the ear-mounted sound generating device 10, the user moves the main body casing 11 so that the head 12 is positioned in the ear depression 1b, so that the user can hear the earlobe at the clip portion (13: FIG. 2). The position where 1c is sandwiched is selected.

  The outer peripheral surface of the head 12 is loosely held on the inner wall of the ear recess 1b. Since the projection 1d of the ear covering the ear hole 1a presses the head 12 and restrains the main body housing 11 on the ear surface, the head 12 falls off the ear dent 1b even if intense exercise is performed. Is blocked. Further, the ridge portion 11m of the main body casing 11 rising from the head 12 abuts against the ear protrusion 1d, so that the head 12 is loosely pressed against the portion of the ear recess 1b facing the ear protrusion 1d. ing. Thereby, even if the force which pinches the earlobe 1c with a clip part (13: FIG. 2) is small, the main body housing | casing 11 is hold | maintained firmly with little position shift on an ear surface.

(Method of operation)
As shown in FIG. 2, the display unit 51, the ON / OFF switch 53, and the setting switches 54 and 55, which are examples of the setting unit, are the speed and duration of rhythm 1, which is an example of the first rhythm, An operation for setting the speed and duration of rhythm 2, which is an example of the second rhythm with different speeds, is possible.

  The main body case 11, which is an example of a case, is attached to the ear and holds the display unit 51, ON / OFF switch 53, setting switches 54 and 55, integrated circuit 50, battery 61, and electronic buzzer element 62.

The ON / OFF switch 53 is provided on the back surface of the main body casing 11 and turns on / off the operation of the ear-mounted sound generator 10. Each time the on / off switch 53 is pressed once for a short time, the ear-mounted sound generator 10 switches between an ON state in which rhythm sound is continuously generated and an OFF state in which the power is turned off and no rhythm sound is generated.

The display unit 51 is housed in the main body housing 11 and displays a numerical value. The display unit 51 can visually recognize the displayed numerical value from above. A pair of setting switches 54 and 55 are arranged on both side surfaces sandwiching the end surface on the clip portion 13 side of the main body casing 11. The ear-mounted sound generator 10 can change the rhythm parameters displayed on the display unit 51 by pressing the setting switches 54 and 55.

The ear-mounted sound generator 10 can be shifted to a setting mode in which the speed and duration of two types of interval rhythms to be described later can be arbitrarily set by using a long press of the ON / OFF switch 53. When the on / off switch 53 is held down for a long time, the ear-mounted sound generator 10 starts the setting mode, and the number of beats per minute of the currently set rhythm is displayed on the display unit 51. When the setting switch 54 is pressed while the number of beats per minute of the rhythm is displayed on the display unit 51, the number of beats per minute displayed on the display unit 51 increases in increments of 10 each time the switch is pressed. When the setting switch 55 on the opposite side of the setting switch 54 is pressed, the number of beats per minute displayed on the display unit 51 is decreased by 10 increments each time it is pressed. Using the three-digit numerical value displayed on the display unit 51, it is possible to set the number of beats per minute in the range of 0 to 200. In this way, a desired number of beats per minute is set in the ear-mounted sound generator 10 .

When the ON / OFF switch 53 is pressed while the number of beats per minute of the rhythm is displayed on the display unit 51, the duration time of the rhythm currently set is displayed on the display unit 51 in minutes. When the setting switch 54 is pressed in a state where the rhythm duration is displayed on the display unit 51, the numeric value of the duration displayed on the display unit 51 is incremented by 1 each time the switch is pressed. When the setting switch 55 on the opposite side of the setting switch 54 is pressed, the numerical value of the duration displayed on the display unit 51 is decreased by 1 each time the switch is pressed once. Using the three-digit numerical value displayed on the display unit 51, it is possible to set the duration in 1 minute increments in the range of 0 to 999 minutes. In this way, a desired duration is set for the ear-mounted sound generator 10 .

A volume switch 56 is disposed on the end face of the main body housing 11 on the clip portion 13 side. The ear-mounted sound generator 10 can switch the volume of the rhythm sound in two steps, large and small, by sliding the volume switch 56.

(Internal structure)
FIG. 3 is an explanatory diagram of the assembly structure of the ear-mounted sound generator . As shown in FIG. 3, the clip portion 13 is rotatably attached to the column portion 14 of the lower housing 11b by a pin 13p. With the spring structure 13b provided in the clip part 13, the clip part 13 constitutes a detent mechanism between the lower housing 11b and sandwiches the ear.

A circuit board 60 is disposed between the upper casing 11a and the lower casing 11b. On the lower surface of the circuit board 60, an integrated circuit 50 of microcomputer elements constituting the rhythm generation circuit and control circuit of the ear-mounted sound generation device 10 is disposed. The display unit 51 is disposed on the upper surface of the circuit board 60. The display unit 51 is a liquid crystal element that can display a 3-digit or 4-digit numerical value. On the circuit pattern of the circuit board 60, a dome contact 53b which is an electrode of an ON / OFF switch (53: FIG. 2) is arranged. The push button 53a is held by the upper housing 11a so as to be movable up and down, and presses the dome contact 53b.

  On the upper surface of the circuit board 60, a common electrode 57, which is an electrode of the setting switches 54 and 55, and switch electrodes 54b and 55b are attached. The movable portions of the switch electrodes 54b and 55b are arranged to face the end portions 54c and 55c of the common electrode 57. The push buttons 54a and 55a are movably held in the upper housing 11a and press the movable parts of the switch electrodes 23b and 24b from the outside.

  An electronic buzzer element 62 is accommodated in the lower head 12b, and is connected to the circuit board 60 by a fixed wiring (not shown). The electronic buzzer element 62 has an outer peripheral portion fixed to the lower head 12b and a central portion that vibrates to generate a rhythm sound.

  Electrode terminals 61 a and 61 b are fixed to the lower surface of the circuit board 60. The circuit board 60 is supplied with power from the battery 61 which is a button battery accommodated in the battery holder 12c through the electrode terminals 61a and 61b. The negative electrode on the upper surface of the battery 61 is in contact with the electrode terminal 61a. The surface other than the upper surface of the battery 61 is a plus electrode, and the side surface of the battery 61 is in contact with the electrode terminal 61b.

  When the battery 61 is exhausted, the user pulls out the battery holder 12c from the head 12 of the main body casing 11 shown in FIG. 2 and replaces the battery 61 with a new one.

(circuit diagram)
FIG. 4 is an explanatory diagram of a circuit diagram of the ear-mounted sound generator . FIG. 5 is an explanatory diagram of a rhythm signal. In FIG. 5, (a) is an interval mode, (b) is a single rhythm mode, (c) is a timer mode, and (d) is a rhythm switching notice.

  As shown in FIG. 4, the integrated circuit 50 is supplied with power from the battery 61 and outputs a rhythm signal to the electronic buzzer element 62. A battery 61, which is an example of a battery, supplies power to the integrated circuit 50. The integrated circuit 50 holds the program and data read from the ROM 50c in the RAM 50b, and the CPU 50a executes rhythm output control and rhythm setting control. The integrated circuit 50 outputs a rhythm signal according to a program and displays a numerical value on the display unit 51.

  The integrated circuit 50, which is an example of the signal generation unit, alternately switches the first rhythm signal and the rhythm 2 signal according to the speed and duration set by the display unit 51, the ON / OFF switch 53, and the setting switches 54 and 55. Output. The integrated circuit 50 changes the numerical value of the rhythm parameter displayed on the display unit 51 in accordance with the operation of the ON / OFF switch 53 and the setting switches 54 and 55 by the user. The integrated circuit 50 alternately outputs rhythm signals in various modes set by the user by operating the ON / OFF switch 53 and the setting switches 54 and 55.

  The display unit 51, which is an example of a display element, can display a multi-digit numerical value. An ON / OFF switch 53, which is an example of a change switch, inputs an operation for switching the speed and duration of rhythm 1 and rhythm 2 displayed numerically on the display unit 51 in a predetermined order. The setting switch 54, which is an example of an increase switch, inputs an operation for increasing the numerical value displayed on the display unit 51. A setting switch 55, which is an example of a decrease switch, inputs an operation for decreasing the numerical value displayed on the display unit 51.

  As shown in FIG. 5A, in the interval mode, when the user presses the ON / OFF switch 53 briefly, the integrated circuit 50 has two types of rhythm speeds until the ON / OFF switch 53 is pressed briefly next time. The rhythm is output alternately. The interval mode, which is an example of the first mode, alternately outputs two types of rhythms in which the rhythm speed and duration are set. For the rhythm signals of rhythm 1 and rhythm 2, as described above, the rhythm output time and rhythm speed can be arbitrarily set. The electronic buzzer element 62, which is an example of a sound generator, is driven by a rhythm signal output from the integrated circuit 50 to generate a rhythm sound.

  As shown in FIG. 5B, in the single rhythm mode (metronome mode), when the user presses the ON / OFF switch 53 briefly, the integrated circuit 50 continues until the ON / OFF switch 53 is pressed briefly next time. Continue to output rhythm 1 at one rhythm speed.

  As shown in FIG. 5C, in the timer mode, when the user presses the ON / OFF switch 53 for a short time, the integrated circuit 50 performs time counting without outputting a rhythm signal, and counts up the set time. Then, an alarm sound is output. A rhythm signal with a beat number of 120 is output for 3 seconds so that the user can confirm the operation at the start of the time count.

(Interval mode)
FIG. 6 is a flowchart for controlling the rhythm output in the interval mode. As shown in FIG. 6, every time the ON / OFF switch 53 is pressed for a short time (S11, S14, S18), the CPU 50a repeats ON / OFF of the rhythm output in the interval mode that alternately repeats two types of rhythm speeds.

  When the ON / OFF switch 53 is pressed briefly in the OFF state of the rhythm output (Yes in S11), the CPU 50a outputs the rhythm 1 while displaying the remaining time of the rhythm 1 on the display unit 51 and counting down (S12). (S13).

  If the ON / OFF switch 53 is pressed for a short time (Yes in S14), the CPU 50a stops the rhythm output (S20), but if not pressed (No in S14), the CPU 50a continues the rhythm output (S15).

  When the output time of rhythm 1 is counted up (Yes in S15), the CPU 50a displays the remaining time of rhythm 2 on the display unit 51 and counts down (S16), and outputs rhythm 2 (S17).

  When the ON / OFF switch 53 is pressed for a short time (Yes in S18), the CPU 50a stops the rhythm output (S20), but if not pressed (No in S18), the CPU 50a continues the rhythm output (S19).

  When the output time of rhythm 2 is counted up (Yes in S19), the CPU 50a outputs the rhythm 1 while displaying the remaining time of rhythm 1 on the display unit 51 and counting down (S12).

  Here, during the output of rhythms 1 and 2, the remaining time of rhythms 1 and 2 is displayed on display unit 51. However, during the output of rhythms 1 and 2, the number of beats per minute of rhythm speeds of rhythms 1 and 2 is displayed. You may display on the display part 51. FIG. The remaining time of rhythm 1 (2) and the rhythm speed of rhythm 1 (2) may be displayed alternately, for example, every 10 seconds.

(Rhythm setting)
FIG. 7 is a flowchart of rhythm setting control of the ear-mounted sound generator . As shown in FIG. 7, when the ON / OFF switch 53 is continuously pressed for 2 seconds (Yes in S31), the CPU 50a starts the rhythm setting mode (S32). In the rhythm setting mode, the speed of rhythm 1, the output time of rhythm 1, the speed of rhythm 2, and the output time of rhythm 2 can be set in order.

  When the ON / OFF switch 53 is continuously pressed for 2 seconds (Yes in S31), the CPU 50a displays the number of beats per minute of the rhythm 1 already set on the display unit 51 and blinks (S32). The CPU 50a allows the user to change the setting of the number of beats per minute of the rhythm 1 through the setting switches 54 and 55 (S33).

  When the ON / OFF switch 53 is pressed for a short time (Yes in S35), the CPU 50a displays the numerical value of the rhythm 1 duration that has already been set on the display unit 51 to blink (S36). The CPU 50a allows the user to change the setting of the rhythm 1 duration through the setting switches 54 and 55 (S37).

  When the ON / OFF switch 53 is pressed for a short time (Yes in S39), the CPU 50a displays the number of beats per minute of the rhythm 2 already set on the display unit 51 and blinks (S40). The CPU 50a allows the user to change the setting of the number of beats per minute of the rhythm 2 through the setting switches 54 and 55 (S41).

  When the ON / OFF switch 53 is pressed for a short time (Yes in S43), the CPU 50a displays the numerical value of the duration of the rhythm 2 that has already been set on the display unit 51 and blinks (S44). The CPU 50a allows the user to change the setting of the duration of rhythm 2 through the setting switches 54 and 55 (S45).

  When the ON / OFF switch 53 is continuously pressed for 2 seconds or the switch operation is interrupted for 5 seconds (Yes in S34, Yes in S38, Yes in S42, Yes in S46), the CPU 50a is in the rhythm setting mode. Is finished (S48), and rhythm output is started (Yes in S11: FIG. 6).

(Volume difference and switching notice)
FIG. 8 is a flowchart of the control of the interval end notice. If the moving speed is high during walking or running, the noise increases due to the sound of the wind and the concentration of listening to the rhythm sound also decreases. For this reason, as shown in FIG. 5A, the ear-mounted sound generator 10 increases the volume when the rhythm speed is high compared to when the rhythm speed is low so as not to miss the rhythm. On the other hand, when the speed is low, the concentration of listening to the sound increases and the rhythm sound can be heard loudly, so the volume is lowered so as not to feel noisy. When one of the rhythm 1 and the rhythm 2 is set to have a higher rhythm speed than the other, the integrated circuit 50 makes the output of the signal that is set larger than the output of the other signal.

In addition, if the rhythm speed is suddenly switched while feelings are not ready, it may not be possible to cope with rhythm changes. For this reason, as shown in FIG. 5D, the ear-mounted sound generator 10 outputs a rhythm in two beats and switches the rhythm to a triple beat when the remaining time is 10 seconds. As a result, the change of the rhythm speed is predicted and the shock at the change is reduced. In FIG. 5A, for the convenience of illustration, rhythm 1 and rhythm 2 are described in a two-beat rhythm from the beginning to the end. However, in reality, both the rhythm 1 and the rhythm 2 are changed to the rhythm of the triple time for the last 10 seconds. The integrated circuit 50 changes the type of rhythm before a predetermined time before the set duration time of at least one of rhythm 1 and rhythm 2 ends.

  As shown in FIG. 8, in the interval mode, the CPU 50a outputs a rhythm signal of rhythm 1 with two beats of strong and weak pulses (S51).

  When the number of beats per minute of rhythm 1 is equal to or higher than the number of beats of rhythm 2 (Yes in S53), the CPU 50a makes the amplitude of the rhythm signal of rhythm 1 larger than the amplitude of the rhythm signal of rhythm 2 (S54). When the number of beats per minute of rhythm 1 is less than the number of beats of rhythm 2 (No in S53), the CPU 50a makes the amplitude of the rhythm signal of rhythm 1 smaller than the amplitude of the rhythm signal of rhythm 2 (S55).

  The CPU 50a continues the double rhythm until the remaining time reaches 10 seconds (No in S56) (S51). When the remaining time reaches 10 seconds (Yes in S56), a triple rhythm is output (S51).

(Single rhythm mode and timer mode)
FIG. 9 is a flowchart of the single rhythm mode and the timer mode. The ear-mounted sound generator 10 can be operated to select and set one mode from a plurality of modes. The ear-mounted sound generator 10 can be used as a metronome by setting the set time of the rhythm 1 duration to “0”. In the single rhythm mode, which is an example of the second mode, one type of rhythm in which the rhythm speed is set is output. As shown in FIG. 5B, only rhythm 1 is continuously output at the set number of beats per minute of the rhythm speed. When the duration of rhythm 1 is set to 0, the integrated circuit 50 continues to output the rhythm 1 signal.

In addition, the ear-mounted sound generator 10 can be used as a timer by setting the number of beats per minute of the rhythm speed of rhythm 1 to “0”. In the timer mode, which is an example of the third mode, an alarm is output when the set duration has elapsed. As shown in FIG. 5C, the time count is executed without generating a rhythm sound, and an alarm sound is output near the ear hole at the end of the time count of the set time. When the rhythm 1 speed is set to 0, the integrated circuit 50 outputs an alarm sound signal different from the normal rhythm sound at the end of the rhythm 1 duration.

  As shown in FIG. 9, when the ON / OFF switch 53 is pressed for a short time (Yes in S61), the CPU 50a simply sets the duration of the rhythm 1 to “0” (Yes in S63). One rhythm mode (metronome mode MM) is executed.

  In the metronome mode MM, the CPU 50a displays the number of beats per minute of the rhythm speed of the rhythm 1 on the display unit 51 (S64), continues to output the rhythm 1 (S65), and then the ON / OFF switch 53 is pressed shortly. If it is (Yes in S66), the output of rhythm 1 is stopped (S67), the power is turned off, and the display on the display unit 51 is turned off (S68).

  When the ON / OFF switch 53 is pressed for a short time (Yes in S61), the CPU 50a sets the timer mode when the number of beats per minute of the rhythm speed of the rhythm 1 is set to “0” (Yes in S62). Execute (MT).

  In the timer mode MT, the CPU 50a displays the remaining time of the rhythm 1 set time on the display unit 51 and counts down (S71). When the remaining time of the rhythm 1 set time becomes 0 (Yes in S72), an alarm is generated. A signal is output (S73). Thereafter, when the ON / OFF switch 53 is pressed for a short time (Yes in S74), the alarm signal is stopped (S75), the power is turned off, and the display on the display unit 51 is turned off (S68).

(Effect of Embodiment 1)
In the first embodiment, the ear-mounted sound generation device 10 is small and light and is supported by being engaged with the ear. Therefore, as compared with the case where the rhythm is heard with headphones using an IC recorder or a smartphone, It is highly portable and does not get in the way when repeating intense and gentle exercises using interval mode.

  In the first embodiment, the ear is sandwiched between the main body housing 11 and the clip portion 13 in a state where the electronic buzzer element 62 is held in a recess around the ear hole. For this reason, the rhythm can be used at an extremely small volume, and the rhythm sound does not leak around and does not cause trouble.

In the first embodiment, the rhythm 1 signal and the rhythm 2 signal are alternately output at the speed and duration set using the display unit 51. For this reason, it is possible to freely set a combination of an arbitrary speed and duration by operating only the ear-mounted sound generating device 10 at an arbitrary place without requiring a power source or equipment for setting. And interval training can be started immediately.

  In the first embodiment, when the duration of rhythm 1 is set to 0, it can be used as a normal metronome. For this reason, it can be used not only for interval training but also for musical instrument performance, music practice, dance practice, golf practice and the like. The rhythm speed can be set by a procedure similar to the setting of the interval mode. Since a special numerical value of 0 is used among the specified numerical values, switching between the interval mode and the metronome mode is easy to understand intuitively, and there is an unexpectedness of duration = 0 → continuous output, so it is difficult to forget the operation procedure.

  In Embodiment 1, when the speed of rhythm 1 is set to 0, it can be used as a normal timer that does not generate rhythm sound. For this reason, it can be used not only for interval training but also for alarm clocks, examinations, exercises, and break management. Further, since a special numerical value of 0 is used among the specified numerical values, the set time can be set by a procedure similar to the setting of the interval mode. For this reason, it is easy to intuitively understand the switching between the interval mode and the timer mode, and there is an unexpectedness of beats per minute 0 → timer, so it is difficult to forget the operation procedure.

  In the first embodiment, of the rhythm 1 and the rhythm 2, the rhythm speed is larger when the rhythm speed is larger than when the rhythm speed is smaller. For this reason, a sensuous volume difference between rhythm 1 and rhythm 2 is reduced, and interval training can be executed comfortably.

  In the first embodiment, the type of rhythm changes from double to triple time before a predetermined time for which the rhythm 1 and rhythm 2 have been set. Therefore, it is possible to comfortably execute interval training by predicting the rhythm switching time.

<Other embodiments>
In the first embodiment, the earlobe 1c is sandwiched between the main body casing 11 and the clip portion 13 to hold the ear-mounted sound generator 10 on the ear surface. However, the ear-mounted sound generator may be mounted on the ear in other forms. For example, a housing similar to a so-called canal-type hearing aid that is inserted into an ear hole may be implemented. May be implemented.

  Although the battery 61 is a button battery in the first embodiment, it may be a dry battery, an air battery, a lithium ion battery, or the like. The display unit 51 may be implemented by a display element other than a liquid crystal element, that is, an LED display element, an organic EL element, electronic paper, or the like. The output unit is not limited to the electronic buzzer element 62 and may be implemented by a speaker.

  In the first embodiment, each time the ON / OFF switch 53 is pressed, the rhythm 1 speed, the rhythm 1 duration, the rhythm 2 speed, and the rhythm 2 duration are sequentially displayed on the display unit 51. Then, the numerical values displayed on the display unit 51 by the setting switches 54 and 55 can be changed. However, the type of rhythm 1 following the speed of rhythm 1 and the type of rhythm 2 following the speed of rhythm 2 are displayed on the display unit 51 so that the type of rhythm can be changed by the setting switches 54 and 55. Good. As the type of rhythm, the display unit 51 may display 1-1, 2-time as 2-1, 3-1 as 3-time, 4-1 as 4-time, 4-1 as rock rhythm, and the like.

  In the first embodiment, the change of the rhythm speed is notified by changing the time signature to the time signature. However, the rhythm parameter to be changed for the advance notice is not limited to the type of rhythm. For example, the switching of the rhythm speed may be notified by the amplitude (that is, the volume) of the rhythm signal, temporary noise output or output stop, voice message, etc. 10 seconds before the switching of the rhythm speed.

  In the first embodiment, the interval mode, the single rhythm mode, and the timer mode are switched over the extension of the rhythm parameter setting operation. However, the volume switch 56 shown in FIG. 2 may be used for switching between these three modes instead of switching the volume. As indicated by a broken line in FIG. 4, a three-stage shift position (56e) may be provided in the volume changeover switch 56, and the three-stage shift positions may be assigned to the interval mode, the single rhythm mode, and the timer mode, respectively.
