Description

The present invention relates to a rotary type flying play equipment represented by Frisbee and thrown by a player by hand.

Conventionally, some traveling toys such as automobiles generate an engine sound, a siren sound, and the like as the vehicle travels, but there are no rotating flight playground equipment such as a Frisbee or a boomerang equipped with sound generating means. SUMMARY OF THE INVENTION The present invention provides a flying playground equipment that includes sound generating means and that draws attention from the surroundings by automatically radiating sound with a sense of speed and comical feeling during flight, thereby increasing interest.

While Frisbee and boomerang are popular as simple playground equipment, play is a repetitive movement of throwing and receiving, and it is monotonous. Therefore, there was a problem of getting bored immediately.

In order to solve the problems in the previous period, the present invention provides sound generating means in a flight play equipment such as a Frisbee or boomerang.

The sound generating means is a whistle or a resonator that uses the wind received when the flying toy is flying, or an electronic device that generates sound using its own energy source.

Whistle and resonators generate sound by the wind received by flight and rotation.

The electronic device which is the sound generating means is an oscillation circuit, an amplifier, a combination of a speaker and a battery, or a sound source memory, an amplifier, a combination of a speaker and a battery.
The electronic device operates by turning on the power switch, and sends out the oscillation sound or the sound recorded in the sound source memory from the speaker.

When the electronic device is a combination of a sound source memory, amplifier, speaker and battery, and when further combined with a control mechanism, it is randomly selected from a plurality of sound source information recorded in the sound source memory each time it flies. Also, the sound volume is changed and new sound source information is created and sent to the amplifier.

In the case where the sound generating means is an electronic device, in order to operate only during flight, control for starting the operation of the control mechanism is performed by a separately provided flight detection means.

The flight detection means uses the wind received when flying, or uses the rotating centrifugal force during flight. The thing using wind is a thing composed of a wind pressure plate and a switch for detecting the position of the wind pressure plate. A device that uses rotation includes a weight and a switch that detects the position of the weight that is moved by the centrifugal force caused by the rotation. An example is a mercury switch composed of mercury and a contact in a sealed case.
When these switches are turned on by flight, the electronic device as the sound generating means is electrically operated.

According to the present invention, the flying playground equipment generates various sounds during the flight, thereby attracting attention from the surroundings and increasing the interest as a game.

In addition, when the sound generating means is a whistle or a resonator, it is possible to provide a sound generating apparatus that does not impair the portability, lightness, and robustness that are important as the characteristics of the play equipment even if it is an electronic device.

By making the sound generating means an electronic device, it is possible to provide means for easily generating sound and controlling sound generation.

By providing the flight detection means, it is possible to automatically generate sound when flying. Moreover, useless consumption of the battery can be avoided.

When the electronic device as a sound generation means is a simple oscillator, even if a control circuit is attached, it is a simple change such as changing the volume of a single tone periodically or changing the frequency periodically. Although it is difficult to create sound, it is possible to freely create unique sound quality, sound volume, etc. suitable for a frisbee flight by combining an electronic device with a sound source memory, an amplifier, and a speaker.
Further, by adding a control mechanism, it is possible to generate a variety of sounds by changing the combination of sound information in the sound source memory or changing the volume at random every flight. Therefore, it is possible to further increase the interest of what kind of sound will be produced next.

Embodiments of the present invention will be described below.
FIG. 1 is a cross-sectional view of a Frisbee equipped with an electronic device of the present invention. As shown in FIG. 1, the electronic circuit 2 and the vibration actuator 3 are installed by the holder 6 in the center part inside the Frisbee 1, and the batteries 4a and 4b mercury switches 5a and 5b are installed on both sides of the outer edge. The electronic circuit 2, the vibration actuator 3, and the battery 4 constitute an electronic device as sound generating means.

With this arrangement, even when the Frisbee flies and collides with the ground or wall, or when it is received by a person, the electronic device or battery does not collide directly, and a robust structure as a whole can be realized.

The vibration actuator 3 attached to the disk part of the Frisbee 1 by the holder 6 directly constitutes a speaker by vibrating the disk part of the Frisbee 1 directly. (See Patent Document 1) Patent Document 1 discloses a method of constructing a flat speaker by directly attaching a vibration actuator to a diaphragm.
In this embodiment, a direct vibration type speaker using a vibration actuator is shown. However, a thin cone type conventional speaker may be attached to the disk portion.

The mercury switches 5a and 5b are installed on the outer edge portion where the centrifugal force is large, and are arranged in an attitude that is turned on when the internal mercury moves outward due to the rotational centrifugal force when the Frisbee flies. If there is only one mercury switch, the switch will be turned on depending on the direction of gravity when holding the frisbee in the hand or placing it in a standing position. If two mercury switches are installed in a position that turns on when the centrifugal force works outward, both will not turn on at the same time due to gravity in any position when not rotating. If the mercury switches are connected in series, both are turned on only when rotating, so that it acts as a rotation detector. The two mercury switches are placed symmetrically with respect to the center of rotation.
In this embodiment, a mercury switch is used, but anything may be used as long as it operates similarly by centrifugal force.

FIG. 2 is a block diagram of an electronic device which is a sound generating means. The control mechanism 8 appropriately selects from a plurality of sound source information recorded in advance in the sound source memory 7, reads a plurality of sound source information, changes the length, tone color, volume, etc., and sends the information to the converter 9. The converter 9 converts sound source information into an acoustic signal. The acoustic signal is sent to the amplifier 10 to drive the vibration actuator 3.
The disk portion of the Frisbee 1 that is vibrated by the vibration actuator 3 acts as a speaker diaphragm and generates sound.

The control mechanism 8, the sound source memory 7, the converter 9, the amplifier 10, and the power switch 11 are constructed as an electronic circuit 2 on a single substrate.

The sound source memory 7 is a ROM in which a plurality of sound source information is recorded in advance. The sound source information is obtained by quantifying, for example, the frequency, intensity, and intermittent period of sound.
Here, the intermittent cycle is, for example, a repetition cycle of an intermittent sound of beep, beep, and beep for a continuous sound of beep.

The control mechanism 8 includes a microcontroller, ROM, and RAM. Software for controlling the microcontroller is written in the ROM, and the entire circuit is controlled. The control mechanism 8 has software random number generation means, and generates a different random value every time the Frisbee rotates and the mercury switches 5a and 5b are simultaneously turned on. Further, the control mechanism 8 reads specific information from a plurality of sound source information recorded in the sound source memory 7 based on the random number value, and writes it into the RAM. In the written sound source information, information on the length, frequency, intensity, etc. of the sound is corrected based on a random value.

It is also possible to set a dip switch (not shown) attached to the control mechanism 8 and correct the sound source information by a combination of this setting information and a random value.

By this operation, acoustic information having infinite variety can be generated from a finite number of sound source information recorded in the sound source memory 7. As a result, a different sound can be generated every flight.
In addition, it is not left to the control mechanism 8, but the user's favorite sound can be selected by setting a dip switch attached to the control mechanism 8.

Even when there is no control mechanism 8 having a random number generation means, a different sound can be generated every flight by reading out a plurality of sound sources recorded in the sound source memory 7 in order. In this case, a finite number of types of sounds recorded in the sound source memory 7 are repeated.

The sound source information written in the RAM of the control mechanism 8 is sent to the converter 9, where it is decoded and converted into an analog acoustic signal.

Next, a series of operations when this embodiment is used for play will be described. Before starting the game, the power switch 11 is turned on. The control mechanism 8 initializes the microcontroller, generates an initial random number, reads a plurality of sound source information from the sound source memory 7 based on the random number value, stores the information in the RAM, and then corrects the sound source information based on the random value. When the Frisbee is thrown while rotating, the mercury switches 5a and 5b which are rotation detecting means are simultaneously turned ON, and the control mechanism reads the sound source information from the RAM and sends it to the converter 9. This information is converted into an analog acoustic signal by the converter 9. The sound signal amplified by the amplifier 10 drives the vibration actuator 3 to generate sound.

When the Frisbee flight ends and the rotation stops, the mercury switches 5a and 5b are turned off. The control mechanism 8 generates the next random number, reads the sound source information from the sound source memory 7 again, and corrects it. This operation is repeated every flight, and a different sound is generated each time.

According to the present invention, it is possible to provide a flying toy that increases the interest as a game and to expand the market for flying toys.
