Description

[Detailed Description of the Invention] Industrial Fields of Use The present invention is used in the health equipment industry for aerobics, jazz dance, and jigging, the sports equipment industry for baseball, golf, and tennis, and the toy industry. The present invention relates to a synthetic sound reproduction device.

2. Description of the Related Art In recent years, with increasing interest in health, an increasing number of people enjoy dancing and jogging while playing music with an emphasis on rhythm. Additionally, an increasing number of people are choosing to practice sports in their free time for fun, rather than acquiring professional-level skills.

These people tried to make their exercise more effective by matching the rhythm of their exercise to the rhythm of the sound being played.

Problems that the invention aims to solveHowever, although the rhythm of one's own movement can be perceived visually, there has been no device that allows the rhythm to be perceived through sound, and there is no existing device for aerobinox or jazz dance. By playing music that emphasizes the rhythm of the person who is exercising, the rhythm of the person's exercise can be matched to the person's will. In other words, there was no heightened awareness of the person exercising due to the sound. On the other hand, in sports such as baseball, golf, and tennis, people practice their practice swings to become better, but the key to becoming better at a sport is when the bat or racket reaches its maximum speed. There is a problem with hitting a ball, but since there is no sound at all during practice swing practice, it is not possible to develop the same feeling as in actual practice.

In view of the above-mentioned problems, the present invention provides a synthetic sound reproduction device that reproduces a synthetic sound in accordance with the rhythm of a person exercising.

Means for Solving the Problems In order to achieve the above objects, the present invention provides an acceleration detection circuit that detects the acceleration of a moving body, an arithmetic circuit that generates a pulse signal based on an output signal of the acceleration detection circuit, and an arithmetic circuit that generates a pulse signal based on an output signal of the acceleration detection circuit. It has a +1.4 configuration comprising a sound source generating section that outputs a predetermined signal based on the sound source, and a speaker that reproduces the output from the sound source generating section as sound.

Effect The present invention has the above-described configuration, so that the acceleration detection circuit can be attached to a moving body, such as the wrist or ankle of a person doing aerobics or jogging, or the wrist of a person playing tennis or golf. Based on the output signal of the acceleration detection circuit, a pulse signal is output when the maximum value of this output signal or the output signal exceeds a certain threshold value. The arithmetic circuit reproduces a pre-written synthesized sound signal, for example, through a speaker, to the sound source generator when the acceleration at that location of the person exercising is extremely high or reaches a predetermined acceleration. A synthesized sound that matches the rhythm of the body will be played.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a synthetic sound reproducing apparatus according to an embodiment of the present invention, and FIGS. 2 and 3 are characteristic diagrams showing temporal changes in acceleration and timing charts showing the relationship between acceleration and pulse voltage.

The acceleration detector 1 is attached to the wrist or ankle, for example,
An output signal S1 is output in accordance with the acceleration of the movement of the moving body such as the wrist or ankle. The output signal S1 is, as shown by the curve in FIG. 2, at time t.

If it starts moving at , the acceleration value gradually increases from zero, reaches the maximum value KM at time tM, and gradually decreases until it reaches zero again at time t2.

For example, when observing a golf or tennis swing, the ball is initially stationary, and the point where the ball is caught is at the very top speed of the swing.
This is the point where the acceleration is at its maximum, and after hitting the ball, the acceleration decreases and the swing comes to a standstill.

The output signal S1 of the acceleration detector 1 is input to an arithmetic circuit 2, which calculates the position of its maximum value and outputs an output signal S2. FIG. 3 shows the relationship between the output signals S1 and 82. As shown in FIG. 3A, the output signal S1 is continuous and the time tM1+tM21 tM3 t tM
The curve M has a maximum value at 4.... This output signal S2 is generated at a time tM1 + tM21 tM31 tM when the acceleration has a maximum value between zero and zero.
It becomes a pulse signal generated at 4...

The output signal S2 is input to the sound wave generator 3, and depending on the timing of the output signal S2, the synthesized sound that has already been input or recorded is output as the output signal S3 and reproduced by the speaker 4.

It should be noted that it is more effective to change the type of output signal S3 of the sound source generator 3 depending on which sport the synthesized sound reproduction device is used for. That is, for example, as shown in FIG. 4, when used for tennis, the sound of the racket hitting the ball is generated in synchronization with the output signal S2. In this way, the sound of the racket hitting the ball will be generated at the moment the racket hits the ball. In golf, there is the sound of a golf ball being hit, and in baseball, there is the sound of a bat hitting a ball.

Note that these sounds may be used by recording the sounds made by celebrities of each sport at two famous locations. Also, as shown in Figure 6, when used for jazz dance, aerobinox, or jogging, the movement of the right wrist produces cymbal sounds.
Rhythm instruments such as tom-tom sounds are played by the movement of the left wrist,
It may also function as an auxiliary device for rhythmically moving the body.

Further, the calculation circuit 2 does not calculate the maximum value of the output signal S1 of the acceleration detector 1, but calculates the pulse signal S2 at time t3 when the acceleration value exceeds a certain threshold of 3, as shown in FIG. It may also be configured to output. In this case, an attempt is made to synchronize the movement of the location where the acceleration detector 1 is attached with the output signal S3 of the sound source generator 3.

That is, when the distance between the acceleration detector 1 and the sound source generator 3 is greater than a predetermined interval, when the sound is played back at the maximum acceleration value, the playback sound will be different from when the actual acceleration detector 1 reaches the maximum acceleration. This is to prevent the time when the signal reaches the ear from being different.

Note that the sound source generator 3 may be integrated with the acceleration detector 1 or may be incorporated in the vicinity thereof, and may be attached to the waist or back via a lead wire (for example, in the case of the back, a tsukusak or a (In the case of the head, it may be a hat, etc.).

Effects of the Invention According to the present invention, the movements of an exercising person, especially the movements of body parts related to the sport, are detected by an acceleration detector, and a synthesized sound from a sound source is generated by a signal calculated by an arithmetic circuit. By controlling playback, rhythm instrument sounds can be played in accordance with wrist and ankle movements in the field of health equipment for aerobics and jogging, allowing you to play sports with a better sense of rhythm.On the other hand, in baseball, golf, and tennis, Since you can hear the sound of each device hitting the ball when the speed of your practice swing is at its maximum, you can develop a feeling similar to that of a real fight while practicing swing, and you can also easily get the feeling of being in a real fight.
