Description

[Detailed explanation of the invention] (Industrial application field) This invention can be incorporated into sewing packages, watches, frames, etc.
It also relates to a melody generating device used for simple talkies and the like.

(Prior Art) Conventionally, this type of melody generating device detects sounds such as hand clapping, shouting, and shouting using a microphone of a sound detection activation switch, and activates a melody generation mechanism to generate a melody. (For example, in the 1980s
49894), or detect static electricity with a static electricity sensor of a static electricity detection activation switch and activate a melody generation mechanism to generate a melody (for example, Utility Model Application No. 60-33016, Utility Model Publication No. 2-46397). (publication), a light sensor of a light sensing activation switch detects light and activates a melody generation mechanism to generate a melody (for example, in 1983-
No. 115590, Japanese Patent Application Laid-open No. 61-56684), and each of these melody generating mechanisms had only one melody injected into them.

(Problem to be solved by the invention) However, when generating a melody, it is necessary to make sounds such as clapping hands, shouting, or calling, or to create static electricity by stroking a sewing bag, or even by simply shining a light on it. However, not only was the method of generating the melody rather uninteresting, but the melody generation mechanism only had one melody injected into it, which halved the interest.

Therefore, this idea was devised to solve the problem mentioned above, and it not only made the means of generating melodies more interesting, but also doubled the interest by increasing the number of melodies. The present invention provides a melody generating device that allows users to play music.

(Means for solving the problem) This invention, as a technical means to solve the conventional problems, consists of a melody IC in which a large number of melodies with different tunes are stored on one side of a board, and each melody IC in this melody IC.

The melody base, which is equipped with an electrolytic capacitor that determines the operating time of the IC, is placed inside a box with a speaker, which is housed in the body of a sewn bag made of an outer skin that allows light to pass through, through a lid plate. The input side of each light-sensing activation switch of this melody base is
An appropriate number of optical sensors for detecting light interruption, which are embedded in the forehead, arms, etc. of the head of the sewing bag, etc., are connected via lead wires and sensing plates, and the output side of each optical sensing activation switch is connected via lead wires and sensing plates. In this case, a dry cell battery placed in a pouch placed over the abdomen of the sewing bag or the like is detachably connected via a lead wire.

(Function) In this invention, the optical sensors of each light sensing activation switch are embedded in the forehead, arms, etc. of the head of the sewing bag, etc. By blocking the light with a hand or the like, one of the optical sensors detects the blocking of light and activates the melody IC via the corresponding light detection activation switch and transistor to generate a melody. Moreover, regardless of whether one melody of the melody IC is being generated or has finished, each time the light from the head, forehead, arms, etc. This is sensed by a light sensor, and other melodies of the melody IC are sequentially generated via a light sensing activation switch and a transistor.

12 and 13 are sensed and the melody of melody IC2 is generated.
Without being limited to this, each optical sensor 11, 1
2 and 13 are built into a watch, forehead, etc., and when the light is blocked when the hands pass or something passes, each light sensor 11, 12, 13 senses the melody IC 2.
