Even in a situation where it is difficult to perform a motion (such as a motion of looking at the display on the wrist), the heart rate can be easily known by the sound.

According to the second invention, it is possible to know the approximate value of the heart rate by dividing a constant heart rate band into a plurality of bands and making different sounds of sounds.

According to the third aspect, the heart rate can be accurately known by notifying the detected heart rate by voice.

[0021]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings. Here, a case where a heartbeat synchronizing sound is used as a sound for notifying the heart rate will be described as an example.

As shown in FIGS. 2 and 3, the heart rate meter according to the present embodiment includes a chest belt 1 attached to the chest of a human body and a heart rate meter main body 2 integrally attached to the chest belt 1. ing.

The heart rate monitor main body 2 is configured as shown in FIGS. 1 and 3. That is, a pair of electrocardiographic electrodes 5 that are in direct contact with the chest, an electrocardiographic detection circuit 6 that is connected to the electrocardiographic electrodes 5 and detects electrocardiogram (R wave), and the electrocardiographic detection circuit 6 detects A waveform shaping circuit 7 for shaping the electrocardiographic waveform and an arithmetic circuit 8 for computing the heart rate from the electrocardiographic waveform signal of the waveform shaping circuit 7 and storing the heart rate and having a function of a stopwatch or a clock. , A display 9 connected to the arithmetic circuit 8 for displaying the heart rate calculated by the arithmetic circuit 8 and a heartbeat synchronizing sound by a heart rate synchronized sound calculated by the arithmetic circuit 8 by a speaker or the like. A notification sound generating unit 10 for issuing a notification from the above, an upper and lower limit setting switch 11 for setting the upper limit value and the lower limit value of the heart rate when the notification sound generating unit 10 is activated to notify the heart rate by sound, An interface for storing the heart rate in the arithmetic circuit 8. Interval setting switch 12 for setting a timer, a watch setting switch 13 for setting a stopwatch or a clock in the arithmetic circuit 8, and a changeover switch 14 for switching whether or not a notification sound is generated by the notification sound generation unit 10. And a branch point moving switch 15 for changing a switching point for switching how to sound the heartbeat synchronizing sound emitted by the notification sound generating unit 10. The difference in how the heartbeat-synchronized sounds are made is by changing the pitch and tone color, but it is sufficient if there are two types of sounds that can be discerned by the human ear. Further, since the display 9 is viewed in a state of being attached to one's chest, the display is upside down.

With the heart rate meter configured as described above, the heart rate is measured as follows.

First, various settings are made. The upper and lower limit setting switch 11 is used to set the upper and lower limit values of the heart rate that match one's physical strength. That is, the notification sound generator 10 is activated to set the upper limit value and the lower limit value of the heart rate band in which the heartbeat synchronizing sound is generated. As an example, the lower limit value is set to 80 and the upper limit value is set to 120. Next, the branch point movement switch 15 is used to set the switching point of how to sound the heartbeat synchronizing sound. For example, it is set to 100.

Further, the interval setting switch 12 and the watch setting switch 13 are appropriately set as needed. The changeover switch 14 is turned on to generate a notification sound.

Next, the heart rate monitor is attached to the chest. That is, the chest belt 1 is wrapped around the chest and the heart rate monitor is attached to the chest. In this state, the detection signal (R wave signal) detected by the electrocardiographic electrode 5 and the electrocardiographic detection circuit 6 is waveform-shaped by the waveform shaping circuit 7 and sent to the arithmetic circuit 8. The arithmetic circuit 8 calculates the heart rate and stores the heart rate at each preset interval. The heart rate calculated by the arithmetic circuit 8 is displayed on the display 9 and emitted by the notification sound generator 10 as a heartbeat synchronizing sound.

The heartbeat synchronizing sound by the notification sound generating unit 10 is emitted in the following manner. That is, according to the above setting example, when the heart rate rises by performing exercise or the like and exceeds 80, a heartbeat synchronizing sound is emitted as a heart rate in the range of 80 to 100, and the heart rate is in the range of 80 to 100. To notify you. Furthermore, when the heart rate rises and exceeds 100, at that point, the heartbeat synchronizing sound is emitted in a different manner, and the heart rate is in the range of 100 to 120.

As described above, since the heart rate monitor is composed of only the chest belt 1 and the heart rate monitor main body 2, the heart rate monitor does not disturb the movement of the limbs such as during exercise.

Further, since the heart rate is notified by sound, it is possible to know the heart rate without causing interference unlike the wireless system.

Furthermore, even when the measurer is in a situation where it is difficult to perform an action other than the exercise such as looking at the display part of the wrist, such as during exercise, it is possible to easily recognize the heart rate by the sound. Become.

In the above embodiment, the upper limit value and the lower limit value are separated by one switching point and the notification is divided into two states (states of heart rate of 80 to 100 and 100 to 120). However, it is also possible to set two or more switching points and set the notification between the upper limit value and the lower limit value in three or more states.

Furthermore, in the above-described embodiment, the heartbeat synchronizing sound has been described as an example of the sound to be notified, but the present invention is not limited to this, and the sound may be notified. In this case, the notification sound generator 10 is equipped with a voice synthesis circuit that synthesizes a voice signal from the heart rate signal from the arithmetic circuit 8. As a result, the heart rate is notified by the synthetic voice at regular time intervals.
