Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a jewel case that makes a sound, and in particular, provides a jewel case that is very surprising because the setting of the acoustic unit cannot be seen from the outside and that works reliably when opened. Is.

[0002]

[Prior art]

 Conventionally, as a jewel case that produces this kind of sound, a sound source circuit and a piezoelectric speaker are housed in the body of the jewel case, and an optical sensor or the like is provided at the end of the body, as in Japanese Utility Model Laid-Open No. 3-55726. There is a device in which a melody or the like is made to flow each time the lid is opened by installing an open / close detection means.

Also, a conventional music box type, in which all the melody generating elements are housed inside the lid, is disclosed in Japanese Utility Model Laid-Open No. 58-88695.

[0004]

[Problems to be solved by the device]

 However, in the former one of the above-mentioned conventional jewel cases that produce a sound, the open / close detection means including an optical sensor is exposed to the outside, which not only spoils the appearance, but also the open / close detection means is provided at the end of the jewel case body. There was a drawback that it took a lot of work to store it in the.

In the latter case, ON / OFF at the time of opening / closing is performed by a switch interposed between the main body and the lid, and since the switches are installed at the hinge portions of both, the durability is difficult. However, there is a drawback that it is troublesome to assemble.

This invention is intended to solve the above-mentioned drawbacks of the conventional example, and not only is it easy to assemble, but also secures the operation of the opening / closing detection means including an optical sensor and covers the mechanism part with a cover. By doing so, it aims to provide a jewel case that produces a sound with greatly improved decorativeness.

[0007]

[Means for solving problems]

 In other words, in the jewel case which makes a sound according to the present invention, a power source, a flat panel speaker, a memory IC storing a melody etc., and an optical sensor are attached to the inside of the jewel case lid, and these are covered by a light-transmitting cover. By covering it, the melody and the like can be played when the lid is opened.

[0008]

[Action]

 Since the jewel case which makes a sound according to the present invention is configured as described above, the mechanism is simpler than the conventional one and the assembly is easy, and the cost can be significantly reduced.

Further, by ensuring the operation of the opening / closing detecting means including an optical sensor and by covering the mechanical portion with the cover, the decorativeness can be greatly improved.

[0010]

【Example】

 Hereinafter, an embodiment of a jewel case which makes a sound according to the present invention will be described in detail with reference to the drawings.

In FIG. 1 and FIG. 2, a jewel case 1 has a main body 2 having a storage portion 3 in which a notch 12 for storing the rings 11 and the like is formed in a cushioning material, and the main body 2 can be opened and closed by a hinge. And a lid 4 connected to. An acoustic unit 5 having the following structure is attached to the lid 4.

That is, the acoustic unit 5 includes a power source 21 formed of a small battery, a flat panel speaker 22 such as a piezoelectric speaker, a memory IC 23 storing a melody and the like, and first and second optical sensors 24 and 24 ′. Has been done. Reference numeral 25 is an amplifier and 26 is a resistor.

The sound unit 5 can be configured such that the melody and words are uttered from the flat panel speaker 22 immediately when the lid 4 is opened by storing appropriate melody and words in the memory IC in advance. .

When mounting the acoustic unit 5 on the lid 4, the printed circuit board 27 supporting the acoustic unit 5 can be fixed to the inner surface of the lid 4 by using an adhesive or the like. At this time, as long as the optical sensors 24 and 24 'are not hidden by the frame of the lid 4 or the like, the mounting work is not required to be highly accurate.

The outside of the acoustic unit 5 is covered with a cover 6 made of light-transmissive cloth or other cloth, non-woven cloth, flocked film or the like. The presence of the acoustic unit 5 is unknown due to the cover 6 because the optical sensors 24 and 24 'are configured to operate by the light transmitted through the cover 6 by adjusting the optical sensors 24 and 24'. Nevertheless, the above melody and words can be announced just by opening the lid 4, which is very surprising. By providing a pair of the optical sensors 24 and 24 'at a predetermined interval, the light is accurately detected and the acoustic unit 5 is activated regardless of the angle of incidence of the light rays when the lid 4 is opened and the shadow. Can be made.

Of course, since nothing is exposed to the outside of the cover 6, the decorativeness of the jewelry case is not impaired.

When using the sound producing jewelry case of the present invention, the optical sensor 24 detects light by simply opening the lid 4, activates the memory IC 23, and outputs a predetermined melody or word from the flat panel speaker 22. .

On the contrary, by closing the lid 4, the melody and the words are immediately stopped.

[0019]

[Effect of device]

 Since the jewel case which makes a sound according to the present invention is configured as described above, the mechanism is simpler than the conventional one and the assembly is easy, and the cost can be significantly reduced.

Further, the operation of the opening / closing detecting means including an optical sensor or the like was ensured, and the decorativeness could be greatly improved by covering the mechanical portion with the cover.
