[Means for Solving the Problems]

 In the musical instrument toy of the present invention, at least one of the two arms is arranged so as to be swingable about a predetermined axis of rotation of the doll body, and each of both ends of the two arms is provided. A half of a percussion instrument is disposed on the arm, and the arm that swings about the predetermined axis of rotation is swung to one side so that the two halves collide with each other to generate a percussion sound. In addition, in the musical instrument toy in which the halves are separated from each other by swinging to the other side to be in a standby state, the predetermined rotation axis is positioned with respect to a vertical axis when the doll body is used. A coil constituting an electromagnet is provided on one of the doll body or the arm swinging about the predetermined rotation axis, and the other coil is excited. Attracted to the coil by magnetic force Other is characterized in that a magnetic force working body repelling.

[0006] According to the musical instrument toy of the present invention, the arm is pivoted to one side by gravity by tilting the rotation axis of the arm at an angle of less than 45 degrees with respect to the axis of the doll body. Since the swinging to the other side is performed by the electromagnet and the magnetic body or another magnet, only two components, the electromagnet and the magnetic body or another magnet, are required for the swinging operation of the arm.

[0007]

[Embodiment of the invention]

 If the angle of the axis of rotation of the arm is too large, the force of descent of the tip of the arm due to gravity increases, so a force for raising the tip of the arm, that is, a large-capacity electromagnet, is required. If the tilt angle of the axis is too small, the descent force of the arm will decrease, and the descent force (responsiveness) will decrease. Therefore, the tilt angle is preferably 3 to 10 degrees. The direction of inclination of the pivot axis of the arm is determined by the position of the center of gravity of the arm, and the pivot axis is moved in the front-rear direction and / or width direction of the doll body, preferably in the rear and / or width direction. Incline. Regarding the arrangement of other magnets or magnetic materials and electromagnets, even if other magnets or magnetic materials are installed on the arm side and the electromagnet is installed on the doll body side, the electromagnets are installed on the arm side, Although the magnetic body may be installed on the doll body side, the electromagnet is provided on the fixed side, that is, the humanoid side, and the permanent magnet or the magnetic body is installed on the arm side, since the electromagnet includes an electric wire for supplying current to the coil. Is preferred. Furthermore, it is not necessary that both of the two arms be swingable, and it is sufficient that one arm is swingable. The phrase “when the doll body is put in use” indicates the normal state when a musical toy is used.

Further, the musical toy of the present invention may be attached to a mobile phone or a bag as a key holder and operated by a calling signal of a telephone, or may be replaced with a signal of a telephone by a sound such as a ringing sound. A sound may be generated. It may also be used as an interior for figurines. As a musical instrument, a cymbal or the like having the same shape may be locked to the ends of both arms, and sound may be generated by colliding them. The struck member may be locked, and the striker may be locked at the tip of the other arm, so that the struck member sounds the struck member. As the doll body, an animal or a character can be employed in addition to a person.
