Thus, even if the user's movement is slightly delayed, the user can make a movement that matches the rhythm of the music.

  Hereinafter, the present invention will be described based on an embodiment shown in the accompanying drawings. The swing type exercise device shown in FIG. 2 is a user who sits on the seat 2 by swinging the seat 2 on which the user sits back and forth and right and left. The seat 2 has a shape imitating the back and saddle of a horse and the upper surface is a seating surface, and a drive that swings the seat 2 in the upper part. The main body 1 containing the portion 3 is arranged, and a reins 6 are arranged on the front end side of the seat 2 and are semicircular and both ends of the seat 2 are connected to the seat 2 so as to be pivotable back and forth. Further, the ridges 7 are suspended from both front sides of the seat 2.

  The drive unit 3 periodically draws, for example, a figure of 8 in front, rear, left, and right on the seat 2 using the rotation of the motor 30 and the link mechanism shown in FIG. The motor 30 has a variable rotational speed and can change the period of the swinging operation. In the figure, reference numeral 4 denotes a control unit that operates the motor 30 via the motor drive circuit 31 and controls the speed of the motor 30.

  The control unit 4 includes an input interface 40 for rhythm synchronization for synchronizing the rocking cycle to a music rhythm (tempo), which will be described later. When the rhythm signal for input is input, the timing (dead point passage timing) for reversing the operation direction at the time of the oscillation coincides with the rhythm signal so that the oscillation cycle is synchronized with the input rhythm signal. Thus, the rotational speed of the motor 30 is changed. The control unit 4 includes a synchronization table 41 relating to the correlation between the rhythm and the oscillation cycle (motor speed). The motor speed is changed based on the data in the synchronization table 41 to change the oscillation cycle. Make a change.

  The rhythm signal for synchronization sent to the input interface 40 is generated by a music signal processing circuit 50 disposed in an adapter 5 externally attached to the swing type exercise device in the example shown in FIG. The music signal processing circuit 50 includes a rhythm extraction unit 52 that extracts a rhythm from music data input through the music signal input unit 51, a rhythm enhancement circuit 53 that emphasizes a rhythm in the music data, and a rhythm enhancement circuit 53. Is provided with a music signal output unit 54 that outputs music data with emphasis on and a rhythm signal output unit 55 that outputs a signal (rhythm signal) at a timing corresponding to the rhythm extracted by the rhythm extraction unit 52. The rhythm signal output from the signal output unit 55 is sent to the control unit 4.

  The music data input to the music signal input unit 51 in the music signal processing circuit 50 is data (analog audio) output from a line output terminal or headphone output terminal of an AV device such as a portable music player 60, a video player, or a television. Data / WAV file) and the music data input from the music signal input unit 51, the rhythm extraction unit 52 performs the following process to extract the rhythm and generate a rhythm signal.

  That is, the rhythm extraction unit 52 extracts low frequency components from the music data through a low-pass filter, and sequentially detects signal level peaks with respect to the low frequency components with reference to a predetermined threshold value. By setting a peak width that ignores data for a predetermined time from the peak rise time, and analyzing the waveform data excluding this peak width, peaks at almost constant intervals are obtained. The rhythm signal is sent from the rhythm signal output unit 55 to the control unit 4 as a pulse signal output in accordance with this peak or a signal having a frequency indicating the average value of peak intervals.

  The rhythm emphasis circuit 53 emphasizes the low frequency component of the music data in accordance with the rhythm extracted as described above. The music signal output unit 54 provides music data with the rhythm emphasized by the rhythm emphasis circuit 53. Is output. Note that music data not emphasized by the rhythm emphasis circuit 53 may be output from the music signal output unit 54 as it is.

  Since the music data output from the music signal output unit 54 is sent to the amplifier 65 to which the speaker 66 is connected, the rhythm is emphasized if the portable music player 60 is connected to the adapter 5 and playback is started. The music data is reproduced by the amplifier 65 and the speaker 66, and at the same time, the movable unit 2 performs a rocking motion in synchronization with the rhythm signal sent from the music signal processing circuit 50. You will be able to exercise according to the rhythm while listening to your favorite music. Moreover, since the rhythm is emphasized in the music data to be played back, the user can accurately grasp the rhythm of the music. The movement corresponding to the movement is performed, and the movement of balancing on the swinging movable part 2 is facilitated, and the movement effect is further enhanced.

  The music signal processing circuit 50 may be a DSP (digital signal processor) in terms of processing speed. The rhythm extraction operation by the rhythm extraction unit 52 is not limited to the one described in the above embodiment, and can be obtained using the autocorrelation value of the waveform data. Further, as the rhythm emphasis circuit 53, for example, a circuit that generates rhythmic music data such as clapping in accordance with the extracted rhythm and superimposes it on the original music data may be used.

  Further, although the music signal processing circuit 50 is disposed in the external adapter 5, the music signal processing circuit 50 may be incorporated in the main body 1 of the swing type exercise device. Of course, the control unit 4 may include a music signal processing circuit 50 (for example, a microprocessor constituting the control unit 4 may be a composite processor including a DSP).

  The amplifier 65 and the speaker 66 can also be incorporated in the main body 1, and headphones may be used in place of the speaker 66. When the speaker 66 is incorporated in the main body 1, the speaker is installed so that the sound reflected on the floor can be heard by the user, and the sound that has been subjected to the surround processing is reproduced. Can listen to comfortable music.

  In the case of using headphones, it is preferable that the user can use wireless headphones using Bluetooth, for example, because the user rides on the movable portion 2 that performs the swinging operation. Further, the music signal input unit 51 may be a microphone input terminal.

  In addition, instead of obtaining music data by connecting an AV device such as a portable music player 60, as shown in FIG. 3, memory means 61 such as a non-volatile memory or hard disk storing digital music data. The music data stored in the memory means 61 may be taken in such a manner that it can be detachably connected. In this case, it is assumed that the music signal processing circuit 50 includes a decoder 57 for supporting digital music data such as PCM and MP3. A network interface 58 may be provided so that music data stored in another network device can be captured through the network.

  The music data may be in a performance information format such as MIDI. In this case, a MIDI sound source is provided in the music signal processing circuit 50, or a MIDI sound source 59 is provided between the music signal processing circuit 50 and the amplifier 65 as shown in FIG. The rhythm extraction unit 52 in the processing circuit 50 may generate a rhythm signal based on the tempo signal in the MIDI signal and the channel signal of the rhythm instrument, and the rhythm emphasis circuit 53 is also a rhythm instrument. A signal that rewrites a channel signal or a velocity code of a low frequency range code can be used. Further, when using MIDI format music data, it is possible to incorporate event information for starting the motor 30 of the driving means by using an extension area in the signal code.

  By the way, there may be a case where the rhythm of the music to be played is too early to synchronize the rocking cycle of the movable part 2 with the rhythm (tempo). The control unit 4 has data describing the adjustable range of the above, and the music signal processing circuit 50 refers to the data and rewrites and reproduces the tempo signal to match the rhythm and the oscillation cycle. be able to. If the rhythm (tempo) is too slow, it can be played back faster. Note that such a process for changing the music playback tempo is not limited to the music data in the MIDI format, and it is easy to use the DSP or the like for the above-described embodiment. Can be realized.

  FIG. 5 shows another embodiment. This is in consideration of the fact that the movement of the user riding on the movable part 2 is slightly out of phase with respect to the swinging movement of the movable part 2. An acceleration sensor 9 is provided, and the control unit 4 that receives an acceleration signal transmitted from the acceleration sensor 9 by wireless or wired communication causes the death of a user's movement (particularly back-and-forth movement) on the swinging movable unit 2. The point timing is detected from the acceleration signal, and the phase of the swinging motion of the movable portion 2 is slightly shifted from the phase of the rhythm signal so that this timing matches the rhythm signal. In this case, the swinging of the movable part 2 performs an operation of turning back slightly earlier than the rhythm, and the movement of the user riding on the swinging movable part 2 matches the rhythm.

Rather than detecting the user's movement using the acceleration sensor 9 , the user's movement delay time corresponding to the speed of the swing cycle is measured in advance, and this delay time is used as correction data as a control unit. Of course, it may be stored in the storage unit 4 and the swing operation may be controlled with reference to the correction data when synchronizing with the rhythm signal. In addition, when creating such correction data, it is preferable to create data according to a user's body shape.

  In the above-described embodiment, the swing type exercise device that loads the user with exercise simulating riding is shown. However, the present invention is not limited to this embodiment, and the user can use the exercise device as shown in FIG. By swinging the standing step portion 91, for example, a load simulating surfing is applied to the user, as shown in FIG. 7, the seat 92 on which the user sits is swung, and each foot of the user is individually The present invention can also be applied to a device that loads a user with an exercise simulating a walking motion by moving the footrests 93, 93 to be moved up and down.
