FIG. 1 shows an interactive learning machine as a configuration of an embodiment of an electronic device to which the present invention is applied. FIG. 1(a) shows a front surface and FIG. 1(b) shows a rear surface. As shown in the figure, the machine includes an outer case 1 having a spherical character design.
Since the outer case 1 does not have a display unit, the eye icon 3 and the light indicator 4 on the crown are provided.

FIG. 2 shows the waterproof case 2 in the outer case 1. Since it has a waterproof mechanism structure of IPx7 that can be used even in a bath, electronic parts such as substrates and various devices are arranged in the waterproof case 2. ing.

As shown in FIG. 1, the outer case 1 has an eye icon 3 and a light indicator on the top of the head that appear to emerge from the inside in an outer upper case 1U formed of a semi-transparent material whose inner surface is painted in a cream color. By changing or blinking the color of No. 4, power ON/OFF, WIFI (registered trademark), ON/OFF, sound reproduction, etc. are notified.
The upper exterior case 1U is attached by screwing onto the lower exterior case 1L.

In addition, a microphone hole 5 is formed in the lower outer case 1L of the outer case 1, a pyroelectric sensor cover 6 is provided in the upper upper case 1U portion above it, and various types are provided on the back side of the lower outer case 1L. Operation keys 7 are provided.

As shown in the figure, the waterproof case 2 maintains a waterproof structure by joining the waterproof upper case 2U to the waterproof lower case 2L with screws 8 sandwiching a waterproof packing (not shown).

In addition, rubber feet 9 are provided at three locations of the exterior case 1 that project below the exterior lower case 1L. The rubber feet 9 are attached by fitting three extension parts 10 projecting downward of the exterior lower case 1L to the waterproof bottom case 2L with screws, and then fitting the rubber feet 9 into the recesses on the lower surface of the extension part 10.

Then, on the upper side surface of the upper waterproof case 2U, a pair of left and right light guides 11 are held by elastic holders 12 made of silicon, and are joined by screws 13.
An electrostatic sensor 32 as a touch sensor and a light emitting unit (LED) 33 are provided in the top of the waterproof upper case 2U (see FIGS. 4 and 5).

FIG. 3 shows a state in which the upper waterproof case 2U is removed, and electronic components such as the speaker 14 and the lithium ion battery 15 are stacked on the lower waterproof case 2L and hold the lithium ion battery 15 so as to wrap it. A main substrate 21, a pyroelectric sensor substrate 23, an eye substrate 25, and a WIFI communication substrate 27 are stacked on the battery holder 16 by screwing or the like, 24 is a pyroelectric sensor, 26 is a light emitting unit (LED), 28 Is a communication module.

That is, the speaker 14 emits sound downward, and the sound is emitted downward through an opening (not shown) provided in the exterior lower case 1L.
The lithium-ion battery 15 is arranged on the speaker 14, the main substrate 21 is on the back side of the battery holder 16, the pyroelectric sensor substrate 23 is on the upper side of the battery holder 16, and the eye is on the upper side of the front side of the battery holder 16. The board 25 and the communication board 27 are screwed to the lower part of the front side of the battery holder 16.

In this way, the interactive learning machine has functions such as the pyroelectric sensor 24 as a human sensor, the electrostatic sensor 32, and communication, and various sensors react and light is turned on.
That is, when the human body is sensed by the pyroelectric sensor 24, the voice is sensed from the microphone hole 5, or the top of the head where the light indicator 4 shines so as to change its color or flashes and rises, is touched by the speaker 14. A sound is emitted or the icon 3 of the eyes that appears to be lit up is emitted.
Specifically, the light from the pair of left and right light emitting portions 26 mounted on the eye substrate 25 is guided by the light guide body 11 to the inside of the outer case 1U formed of a semi-transparent material whose inner surface is painted in a cream color. The eye icon 3 glows as it is guided and emerges in the exterior upper case 1U.

Next, FIG. 4 shows an enlarged vertical cross-section of the upper part of FIG. 1(a). An electrostatic sensor substrate 31 is horizontally screwed in the top of the waterproof upper case 2U. As shown in FIG. 5, an electrostatic sensor 32 having a sensor electrode pattern formed in a substantially U shape having a circular outer shape is provided at 31, and a light emitting portion 33 formed of an LED is mounted at the center.
In addition, between the top of the waterproof upper case 2U and the top of the outer case 1U, there is a position corresponding to the electrostatic sensor 32 and the light emitting unit 33, that is, electrostatic due to the sensor electrode pattern formed in a substantially U shape having a circular outside. The sealed area 34 is hermetically sealed to include the portion facing the sensor 32 and the light emitting portion 33 inside thereof, and the top of the waterproof upper case 2U has a spherical shape protruding upward so that light spreads in all directions. Is formed in the dome-shaped portion 35.

On this dome-shaped portion 35, as shown in FIG. 6, a substantially disk-shaped elastic member 36 made of milky white silicon is fitted into a packing groove 37 formed outside the dome-shaped portion 35 and mounted.
As shown in FIG. 4, the elastic member 36 is in a compressed state in which it is in close contact with the dome-shaped portion 35 of the upper waterproof case 2U and in close contact with the lower surface of the top of the outer upper case 1U, corresponding to the closed space 34. Thus, the waterproof state between the dome-shaped portion 35 and the top of the outer case 1U is maintained.

In this way, by providing the elastic member 36 as a packing between the upper waterproof case 2U and the upper outer case 1U, the electrostatic sensor 32 in the crown of the upper waterproof case 2U changes its capacitance when water is placed on it. It eliminates the problem of malfunction that occurs in.

In addition, since the light emitting portion 33 is in the waterproof upper case 2U, the light of the light emitting portion 33 picks up the shape of the crown of the waterproof upper case 2U and does not diffuse the light uniformly. By mounting the member 36, the light of the light emitting portion 33 does not go out directly, but the light from the light emitting portion 33 passes through the elastic member 36 made of a semi-transparent material, and the outer case 1U also made of the semi-transparent material. Diffuses and emerges at the top of the head.

That is, light is uniformly diffused from the dome-shaped portion 35 in the milky white silicon of the elastic member 36, and further, uniformly passes through the exterior upper case 1U made of a semi-transparent material whose inner surface is painted in cream color. Spread.
Therefore, the illumination of the light indicator 4 with the electrostatic sensor 32 is clear and easy to understand.

When the human body touches the crown of the outer case 1U, the electrostatic sensor 32 senses through the outer case 1U made of a semi-transparent material and the elastic member 36.
That is, as shown in FIG. 5, the electrostatic sensor 32 of the dome-shaped portion 35 of the waterproof upper case 2U has a sensor electrode pattern formed in a substantially U shape having a circular outer side, and therefore, the top portion of the outer case 1U has a top portion. Reacts when you touch the top.

As described above, according to the interactive learning machine of the embodiment, since the sealed area 34 including the position corresponding to the electrostatic sensor 32 is formed between the top of the waterproof upper case 2U and the outer upper case 1U, the outer upper case is formed. Even if the electrostatic sensor 32 is provided in the top of the waterproof upper case 2U covered with 1U, malfunction due to water can be prevented and the function as the touch sensor can be ensured.
