Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a water toy that emits an electronic sound. More specifically, the present invention relates to a water play toy that emits an electronic sound used in a place where water is played, such as a bathroom.

[0002]

2. Description of the Related Art Conventionally, a bath timer (Japanese Utility Model Laid-Open No. 3-4774) has been disclosed as a toy having a waterproof sound generating means used in places where water is played in a bathroom or the like. The above-mentioned conventional bath timer is intended to provide a toy that emits an electronic sound to interest a baby when playing in a place where water is used. However, the toys used in the place where the player plays with water often float on the surface of the water and play, and in order to clearly generate an electronic sound, the speaker is located on the surface of the water and stably faces the outside air. Is preferred. Further, even if the speaker is located on the water surface, if the floating stability of the toy is poor, water adheres to the speaker due to the shaking of the water surface, and it is difficult to generate a clear electronic sound.

[0003]

SUMMARY OF THE INVENTION The present invention aims at solving the above-mentioned disadvantages of the conventional water-playing toy that emits an electronic sound, that is, a place where a clear electronic sound with excellent sound quality is played in the water. It is an object of the present invention to provide a toy that can be generated stably.

[0004]

According to the present invention, there is provided a hollow upper body having a spherical body or a similar shape, and a pillar-shaped hollow lower body connected to a lower portion of the upper body. A speaker that emits at least an electronic sound, a circuit board that controls the electronic sound, and a power supply,
The speaker is housed at an upper surface inside the upper body, and the power source is a water toy that emits an electronic sound and is housed inside the lower body. Further, the main body is formed in the shape of a microphone, and a synthetic resin thin film, a porous resin thin film having both air permeability and waterproofness, or a thin film selected from a porous fiber thin film is arranged on the front of the speaker. And the thin film is selected from a porous polytetrafluoroethylene thin film, a porous thin film mainly composed of polyurethane, or a nonwoven fabric having fine pores.

As the material of the upper body and the lower body forming the main body, rubber or plastic is preferably used.
The upper body is a hollow body having a spherical shape or a similar shape, and the spherical shape may be a hemispherical shape, a disk shape, or a combination thereof. The lower body is a hollow body having a columnar outer shape, and the columnar shape includes a columnar shape such as a columnar shape, a triangular prism, and a quadrangular prism, as well as a conical shape and a pyramid shape.
The main body has a form in which a lower body is connected to the upper body.
Therefore, when floating on the water surface, the upper body plays a role of floating, and since the lower body contains a power source, the center of gravity can be lowered, and the body can float with less shaking.

Conventionally, a general-purpose speaker is used as the speaker that emits the electronic sound. The speaker is fixed to the upper surface inside the upper body directly or via a connection member. In addition, various thin films can be provided on the front surface of the speaker to impart waterproofness, but it is preferable to provide a resin or porous fiber thin film having both air permeability and waterproofness. This is because these thin films can prevent water from entering from the outside due to the above characteristics, and can transmit electronic sound emitted from an internal speaker to the outside. Incidentally, as the thin film, a porous polytetrafluoroethylene thin film, a porous polyurethane thin film,
A thin film having fine communication holes, such as a porous polyamino acid urethane thin film, a porous fluorine-modified polyurethane thin film, a porous fluorine-modified polyamino acid urethane thin film, a mixed porous thin film of polyurethane and polyvinylidene fluoride, and the like.
In addition, even if the resin has almost no pores, it is possible to obtain a thin film having both appropriate air permeability and waterproofness by thinning, for example, a polyester, polyamide, polyolefin, polyurethane resin having a thickness of 10 μm or less. Is mentioned. As a method of forming the porous resin thin film, a general-purpose means has conventionally been used. For example, in the case of a porous polyurethane film, a polyurethane resin dispersion obtained by blending a water-repellent cloth with a water-soluble fine powder is applied to a water bath. After the fine powder has been eluted, the fabric is peeled off. In the case of a porous polytetrafluoroethylene film, the polytetrafluoroethylene powder is dispersed in a medium containing the fine powder to form a paste, and after the medium is removed from a sheet-like molded body formed by extrusion molding, It is obtained by stretching at a temperature not higher than the melting point of polytetrafluoroethylene and, if necessary, firing. The above-described porous resin thin film can be used by laminating it on a support such as a cloth within a range that does not impair air permeability and waterproofness. it can. Examples of the porous fiber thin film include a nonwoven fabric and a knitted fabric having fine pores. The above-described thin film may be provided directly on the front surface of the speaker, or may be provided indirectly on the toy body, such as by locating the speaker on the portion of the body where the thin film is provided.

A circuit board for controlling an electronic sound for generating a desired electronic sound from the speaker includes at least a part for controlling the entire circuit, a part for storing a control procedure, and a part for storing the electronic sound. The audio data sequentially read from the portion storing the electronic sound is converted into an audio signal and output, and emitted from the speaker. Further, it is preferable that the circuit board has a removable voice storage circuit. This is done by replacing the voice storage circuit,
This is because various electronic sounds can be output, and a highly applicable toy that can be used in various playing places can be obtained. Examples of the electronic sound include music, stories, various sound effects, those that count numbers, and those that read out characters and alphabets.

The power source is preferably a dry battery, and may be a primary battery or a secondary battery. It is also possible to obtain electricity from a light source by incorporating a solar cell, or to incorporate a motor and manually rotate the motor to obtain electricity. Further, the power supply is housed in the lower body, thereby lowering the center of gravity of the toy and improving the stability when floating on the water surface.

The loudspeaker, the circuit board for controlling the electronic sound, and the power supply are electrically connected to each other, and may be provided with a switch if necessary. The switch includes a switch for connecting or disconnecting a power supply, a switch for adjusting a volume, and a switch for selecting the electronic sound when a plurality of electronic sounds are stored in a circuit board that controls the electronic sound. . The switch for selecting the electronic sound is a switch for selecting the electronic sound by operating a single switch, or a switch for providing a plurality of switches and selecting the electronic sound by operating one of the switches. Is mentioned.
