Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a voice and motion control method for driving and controlling the motion of a doll or the like in accordance with the progress of music, narration, or the like.

(Prior art and its problems) Conventionally, when moving puppets or changing the state of a fountain in time with music, it was necessary to synchronize with the progress of the music.
Programs are being created to drive and stop drive motors for operating dolls, fountains, etc. In other words, if you want to include a narration for a certain amount of time in the middle of the music and make the puppet move during that time, you need to know how many minutes and seconds from the start of the music the narration starts, and how many minutes the narration lasts. Calculate the number of seconds and program this as a signal to drive and stop the doll movement motor.

However, in this case, the audio recording medium and the doll movement program are independent, and although the doll movement program is synchronized with the time, it is not necessarily synchronized with the music. For example, when the voltage during playback is low, The start of the narration is slightly delayed compared to when inputting the program,
Since the puppet motion motor is operated according to a program, there may be a lag between the narration and the puppet motion. Therefore, it is necessary to strictly manage the synchronization of both.

(Technical Problem of the Invention) The technical problem of the present invention is to solve the above-mentioned drawbacks and, in particular, to propose a control device for a moving object that enables accurate synchronization between the voice and the motor for moving a doll or the like. .

(Means for Solving the Problems) In order to solve the above problems, a control device for an operating body according to the present invention is characterized by having the following requirements.

(a) The control device is provided with a recording medium such as a music cassette tape, a videotape, or a magnetic disk on which an ultrasonic motion drive signal and an audible audio signal are recorded in parallel.

(b) The operating body is provided with an operating mechanism and an ultrasonic sensor that receives an ultrasonic operation drive signal sent from the recording medium, and the ultrasonic operation drive signal received by the ultrasonic sensor. A drive motor is provided which is driven according to the invention and which drives the operating mechanism.

(c) The audible audio signal is converted into an audio signal and output as audio from a speaker.

Note that, together with the operating body, an electrically operated operating element such as a lighting fixture may be controlled in accordance with an ultrasonic operation drive signal received by the ultrasonic sensor.

(Effects of the Invention) As described above, according to the present invention, the ultrasonic motion drive signal for driving the moving body and the audible audio signal are sent at the same time, so there is no possibility that there will be a lag between the movement of the moving body and the sound. Without,
You can always keep the two in sync. Further, when recording the ultrasonic operation drive signal and the audible audio signal, it is possible to record both while checking their waveforms, making the work very easy.

(Example) The present invention will be explained below with reference to the drawings.

In FIG. 1, reference numeral A indicates a control device that controls the motion of a moving object such as a doll. 1 is a cassette tape, on one track 1a of which an ultrasonic drive signal a is recorded, and on the other track lb of the cassette tape 1, an audible audio signal is recorded in parallel. That is, the frequency of sound waves that humans can hear is approximately 200 to 20,000 hertz (H2), and one track 1a of the cassette tape 1 records an ultrasonic operation drive signal a made of sound waves exceeding the audio frequency range. In addition, in another track lb, an audio signal in the above-mentioned audio frequency range is recorded.

Note that the recording medium is not limited to the cassette tape of this example.
It may be a video tape, a magnetic disk, etc. In the case of a videotape, the audio signal may be recorded in the audio recording section, and the ultrasonic operation drive signal a may be recorded in the image recording section.

Furthermore, when recording the ultrasonic operation drive signal a and the audible audio signal on a recording medium, it is sufficient to record them while checking their waveforms.

The control device A also includes an ultrasonic reproducing head 2 that picks up the ultrasonic operation drive signal a of the track Ia.
An ultrasonic amplification circuit 3 for amplifying the ultrasonic operation drive signal a and a speaker 4 are provided. In addition, the control device A
is provided with an audible sound wave reproducing head 5 for picking up the audible audio signal of the track lb, an audio amplification circuit 6 for amplifying the audible audio signal, and a speaker 7.

Next, the operating body B is formed as a flower-like body, and as shown in FIG. 1 and FIG. An ultrasonic sensor 12 having a motor 11 and receiving an ultrasonic operation drive signal a is provided.

The operating mechanism rotates a bendable core member 21 provided in a pot member 20 by a drive motor 11, and the lower end of a stem member 22 with a flower 22a attached to the core member 21 is inserted into the pot member 2o.
The drive motor 11 is configured to be operated by detection by an ultrasonic sensor 12 and a sound sensor 13 provided on the pot member 20.

As shown in FIG. 2(C), an ultrasonic sensor 12 and a sound sensor 13 are connected in series to the drive circuit 8 of the drive motor 11. Thereby, the drive motor 11 is configured to be driven in accordance with the ultrasonic operation drive signal a received by the ultrasonic sensor 12.

In the above configuration, when the control device A is activated, the ultrasonic operation drive signal a recorded on the track la of the cassette tape 1 is picked up by the ultrasonic playback head 2, amplified by the ultrasonic amplification circuit 3, and transmitted to the speaker 4. The ultrasonic wave 9a is output from the ultrasonic wave 9a. Since the ultrasonic sensor 12 provided in the operating body B receives the ultrasonic operation drive signal a from the speaker 4, the switch by the ultrasonic sensor 12 in the drive circuit 8 is turned on. at the same time,
The audible sound signal recorded on the other track lb of the cassette tape 1 is picked up by the audible sound wave reproduction head 5, amplified by the sound amplification circuit 6, and outputted from the speaker 7 as an audible sound wave 9b, so that this sound is operated. The sound sensor 13 provided on the body B detects this, and the switch is turned on. Since the switch by the ultrasonic sensor 12 and the switch by the sound sensor 13 are turned on, the drive circuit 8 of the drive motor 11 is closed, the drive morph 11 is activated, the operating mechanism is activated, and the operating body B moves.

As mentioned above, since the ultrasonic motion drive signal a that drives the moving body B and the audible audio signal S are sent at the same time, there is no difference between the movement of the moving body B and the sound, and the two are always synchronized. be able to. Furthermore, when recording the ultrasonic operation drive signal a and the audible audio signal, it is possible to record both while checking their waveforms, making the work very easy.

As shown in FIG. 3, the drive circuit 8 is configured to be driven directly by the ultrasonic sensor 12 provided on the operating body B only by receiving the ultrasonic operation drive signal a from the speaker 4. In this case, the sound sensor 13 is not necessary. Also, as shown in the figure, the audible audio signal recorded on the cassette tape l is picked up by the audible sound wave playback head 14, and is picked up by the audio amplification circuit 6. After amplification,
The operating body B may be configured to convert the radio waves 15 into radio waves 15 and output them using the audio radio wave oscillator 14.
If this is provided, the sound will be output directly from the speaker 18.

Further, together with the operating body B, an electrically operated operating member such as a lighting fixture (not shown) may be configured to control blinking or the like in accordance with the sonic motion drive signal received by the ultrasonic sensor 12. .
