Abstract

PURPOSE:To enable a highly unexpected interesting movement to be enjoyed by comparing the size of signals inputted to a sensor with a comparator to rotate forward and backward a motor with the output of the comparator for operating a decoration device. CONSTITUTION:The output ends of R and L microphones 41 and 43 are connected respectively to the input ends of R and L amplifiers 45 and 47 to amplify the outputs of the microphones in the amplifiers 45, 47. The amplified signals are inputted to R and L comparators 49 and 51 to be compared, while the output signals are inputted to a reversible motor driving circuit 53 to controllably rotate a motor 55. The motor is rotated in the direction of larger input signal to pivot a rotor of a decoration device. R and L stop switches 57 and 59 connected to the reversible motor driving circuit 53 control the pivotable range of the rotor 2. Thus, when a decoration is mounted on the rotary decoration device and one calls to the decoration, the decoration turns to him.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the structure of a decorative body, and more particularly to the structure of a decorative device that operates by detecting sound, light, etc. using a sensor.

(Prior Art) In recent years, products have been sold that operate by detecting human voices or sounds such as applause using sound sensors.

This means that it is possible to create a situation where it seems as if there is communication between the product and the person.
This is a completely new product, but the mainstream of conventional products is one that performs one operation for one sensor, and no one has been developed that can perform multiple operations by interlocking multiple sensors. There wasn't.

(Technical Problem of the Invention) The present invention makes further use of the above-mentioned characteristics of products that move and operate based on sensor outputs, and can provide an unprecedented and effective surprise to people by moving decorations using multiple sensor outputs. The technical problem is to provide a decorative device that can.

(Means for Solving the Problems) In order to solve the above problems, a rotary decoration device according to the present invention is characterized by having the following requirements. +i) The rotating decorative body has a rotating body that is rotated by a power source such as a motor, and a base that rotatably supports the rotating body, and the rotating body is equipped with at least two or more sensors. .

(2) An amplifier that amplifies the sensor output, a comparator that compares the amplifier output, and a forward/reverse motor drive circuit that is controlled by the comparator output, and the motor drive circuit is controlled by the magnitude of the signal input to the sensor. A control circuit is provided to control the direction of rotation and operate the rotating body.

(Operations and Effects of the Invention) With the above configuration, the comparator compares the magnitude of the signals input to the sensor, and the output of the comparator causes the motor to rotate forward or backward to operate the decoration device. As a result, for example, when a person calls out to someone, the decoration device rotates in response to the input signal that is greater in the voice input to the sensor, and the decoration placed on the decoration device turns around as if it were called by a person. It can work like that.

Therefore, instead of a single movement like the conventional product, you can enjoy a surprising movement.

(Example) Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

FIG. 1 is an external configuration diagram showing a decorative device according to the present invention, in which 1 is a base of the decorative device consisting of a disc-shaped member having a desired thickness, and 2 is a rotating base on the base. A freely placed rotating body; 3 is a power switch for the decoration device; 4a;
A microphone 4b is embedded in the upper part of the rotating body, and is configured to rotate in the direction of the arrow by a motor built into the rotating body 2 based on the volume sensed by the microphones 4a and 4b.

FIG. 2 is a cross-sectional view showing the rotating mechanism of the decoration device shown in FIG.
and a bearing 13.

On the other hand, inside the rotary body 2, a small gear 17 fitted with the large gear 11 and a rotating shaft 19 connected to the small gear 17 are provided, and large and small gears 20 of different diameters are fixed to the rotating shaft 19. ,
Furthermore, a gear of different diameters 21 loosely inserted into the rotating shaft 19 is provided.

Next, gear shafts 23 and 24 are provided on both sides of the rotating shaft 19 in parallel to the rotating shaft 19.
and 24 have different diameter gears 25 and 27 fixed to the shaft, respectively.
is provided. Among these, the large diameter gear 27a meshes with a gear 31 fixed to an output shaft 30 of an electric motor 29,
The small gear 27b meshes with the large gear 21a of the different diameter gear 21. Furthermore, the small gear 21b meshes with the large gear 25a of the gear 25 of different diameters, and the small gear 25b meshes with the large gear 20a of the gear 20 of different diameters.

The electric motor 29 is electrically connected to a control circuit (not shown), and the control circuit can rotate the motor 29 in forward and reverse directions.

Further, the rotating body 2 has an assembled support base housing part 33, and the housing part 33 is provided with a protruding support shaft 35, and the bearing 13 configured on the support base 15 is attached to the housing part 33. By fitting, the lower part of the rotating body is configured so as not to come into contact with the upper surface of the base 1, and the housing part is provided with a slit 33a over almost its circumference, and the slit 33a part is rotated. A small gear 17 fixed to a shaft 19 is configured to engage and move along the circumference of a large gear 11.

Sensor microphones 4a and 4b are embedded in the outer wall of the upper part of the rotary body 2, and the sensor microphones 4a and 4b are connected to a control circuit (not shown), and a power source battery 37 is arranged at the lower part of the rotary body 2.

Therefore, when the motor 29 rotates in the direction of the arrow, the small gear 17 fixed to the rotating shaft 19 also rotates in the same direction as the rotating shaft of the motor 29, and as a result, the rotating body 2 also rotates in the same direction as the motor 29.

Next, the sound sensor control circuit will be explained based on the block diagram shown in FIG.

The output terminals of the R microphone 41 and the L microphone 43 are connected to the input terminals of the R amplifier 45 and the L amplifier 47, respectively.
．． At 47, the output from the microphone is amplified. The amplified signal is input to the R comparator 49 and L comparator 51 provided at the next stage to compare the magnitudes of the two input signals of the R microphone and L microphone, and the output signal is sent to the forward/reverse motor drive circuit. 53, and the motor drive circuit 53 controls the rotation of the motor 55 based on the input signal.

Note that the total gain of the R microphone and the R amplifier and the total gain of the L microphone and the L amplifier are the same. In the circuit configured as described above, when the output of the R amplifier>the output of the L amplifier, the output of the R comparator 49 is output to the forward/reverse rotation motor drive circuit 53 at the next stage, and the motor 55 rotates clockwise.

On the other hand, when the output of the R amplifier is the output of the L amplifier, the output of the L comparator 51 is output to the forward/reverse rotation motor drive circuit 53 at the next stage, and the motor 55 is configured to rotate counterclockwise.

In other words, the motor rotates in the direction of the larger input signal,

In this way, when a decoration is placed on the rotating decoration device and a person calls out to it, the decoration moves as if it were called by someone and turns in the direction of the person who called out. It creates an effect that makes it seem as if there is communication between the object and the object. In addition, if you place a decoration that operates by detecting sound or light instead of artificial flowers, the decoration will be activated by multiple factors such as sound and light, and the rotating body will rotate, making the operation more complicated. can be expressed. Although the embodiments of the present invention have been described using two microphones as sensors, the present invention is not limited to this and may be configured using two or more microphones, and the sensor may be configured to detect audio. It is clear that an optical sensor such as a CCD that detects light or the like may be used instead of a sensor for detecting light.

Further, although the embodiments of the present invention have been described using a limit switch for controlling the rotation range, it is clear that the decoration device may be constructed without providing the switch.

Furthermore, although the rotating decorative body and the decorative body placed on the rotating decorative body have been explained separately, it is obvious that these may be configured integrally.
