A surfactant coating layer 53 is formed by coating the surfactant.

以上、実施形態７の音通過部構造によれば、スピーカカバー４の音通過孔５に外部から水が浸入した場合、その音通過孔５の全体が界面活性剤塗布層５３によって水の表面張力を抑える（弱める）ことから、前記筐体１・２を持って振ることで、音通過孔５内に浸入して残った水分を容易に外部に排出することができる。   As described above, according to the sound passage portion structure of the seventh embodiment, when water enters the sound passage hole 5 of the speaker cover 4 from the outside, the entire surface of the sound passage hole 5 is surface tensioned by the surfactant coating layer 53. Therefore, the water remaining in the sound passage hole 5 can be easily discharged to the outside by shaking with the casings 1 and 2.

さらに、実施形態７では、音通過孔５の中間部よりも外部側が傾斜面の大径部５２となっていることから、水の排出機能が高められる。   Furthermore, in Embodiment 7, since the outer side is the large diameter part 52 of the inclined surface rather than the intermediate part of the sound passage hole 5, the water discharge function is enhanced.

なお、図示例では、音通過孔５の上端側を傾斜面による大径部５２としたが、そのような大径部を持たない音通過孔５の全体に界面活性剤塗布層５３を形成してもよい。また、前述した実施形態１、３〜６のような大径部５１・５２を有する音通過孔５の全体に界面活性剤塗布層５３を形成してもよく、そうすれば水の排出機能が高められる。   In the illustrated example, the upper end side of the sound passage hole 5 is a large-diameter portion 52 formed by an inclined surface. However, a surfactant coating layer 53 is formed on the entire sound passage hole 5 that does not have such a large-diameter portion. May be. Moreover, you may form the surfactant application layer 53 in the whole sound passage hole 5 which has the large diameter parts 51 * 52 like Embodiment 1, 3-6 mentioned above, and, thereby, the discharge function of water is sufficient. Enhanced.

図１１は実施形態８を示すもので、前述した実施形態１、４と同様、４はスピーカカバー、５は音通過孔、５１は曲面による大径部、６は防塵膜であって、８はスペーサ、９は隙間である。 (Embodiment 8)
FIG. 11 shows an eighth embodiment, like the first and fourth embodiments described above, 4 is a speaker cover, 5 is a sound passage hole, 51 is a large-diameter portion with a curved surface, 6 is a dust-proof film, Spacers 9 are gaps.

すなわち、実施形態８では、図示のように、スピーカカバー４の内面には、音通過孔５の下方に位置する防塵膜６が周囲のスペーサ８を介して接着剤により接着して設けられていて、スピーカカバー４の音通過孔５を有する部分と防塵膜６との間に隙間９が形成されている。   That is, in the eighth embodiment, as shown in the figure, the dust cover film 6 located below the sound passage hole 5 is provided on the inner surface of the speaker cover 4 by being bonded with an adhesive via the surrounding spacer 8. A gap 9 is formed between the portion having the sound passage hole 5 of the speaker cover 4 and the dustproof film 6.

以上、実施形態８の音通過部構造によれば、スピーカカバー４の音通過孔５に外部から水が浸入した場合、その音通過孔５の下方の防塵膜６との間の隙間９にも水が浸入することから、前記筐体１・２を持って振ることで、隙間９に浸入して残った水と一緒に音通過孔５内に浸入して残った水分を押し流して容易に外部に排出することができる。   As described above, according to the sound passage portion structure of the eighth embodiment, when water enters the sound passage hole 5 of the speaker cover 4 from the outside, the gap 9 between the sound passage hole 5 and the dust-proof film 6 is also provided below. Since water enters, by shaking with the casings 1 and 2, the water remaining in the gap 9 together with the water remaining in the gap 9 can be easily swept away into the sound passage hole 5 and easily removed from the outside. Can be discharged.

さらに、実施形態８では、音通過孔５の中間部よりも外部側半部及び内部側半部ともに曲面の大径部５１となっていることから、水の排出機能が高められる。   Furthermore, in the eighth embodiment, since the outer half and the inner half of the sound passage hole 5 are both curved large-diameter portions 51, the water discharge function is enhanced.

なお、図示例では、音通過孔５の上半部及び下半部ともに曲面による大径部５１としたが、そのような大径部を持たない音通過孔５としてもよい。また、前述した実施形態１、３〜６のような大径部５１・５２を有する音通過孔５としてもよく、そうすれば水の排出機能が高められる。   In the illustrated example, both the upper half and the lower half of the sound passage hole 5 are curved large-diameter portions 51. However, the sound passage hole 5 may not have such a large-diameter portion. Moreover, it is good also as the sound passage hole 5 which has the large diameter parts 51 * 52 like Embodiment 1, 3 mentioned above, and, thereby, the discharge function of water is improved.

（実施形態９）
実施形態９は、前記スピーカカバー４を、撥水性を有する樹脂材料により形成したものである。 (Embodiment 9)
In the ninth embodiment, the speaker cover 4 is formed of a water-repellent resin material.

以上、実施形態９の音通過部構造によれば、スピーカカバー４の音通過孔５に外部から水が浸入した場合、その音通過孔５を含むスピーカカバー４自体が有する表面の撥水性によって水をはじくことから、前記筐体１・２を持って振ることで、音通過孔５内に浸入して残った水分を容易に外部に排出することができる。   As described above, according to the sound passage portion structure of the ninth embodiment, when water enters the sound passage hole 5 of the speaker cover 4 from the outside, the water is repelled by the surface water repellency of the speaker cover 4 itself including the sound passage hole 5. Therefore, the water remaining after entering the sound passage hole 5 can be easily discharged to the outside by shaking with the housings 1 and 2.

なお、このように、撥水性を有する樹脂材料によりスピーカカバー４を形成する場合、音通過孔５には、前述した実施形態１〜６のような大径部５１・５２を形成しなくてもよいが、大径部５１・５２を形成してもよく、そうすれば水の排出機能が更に高められる。   When the speaker cover 4 is formed of a water-repellent resin material in this way, the sound passage hole 5 does not have to be formed with the large diameter portions 51 and 52 as in the first to sixth embodiments. Although it is good, you may form the large diameter part 51 * 52, and, if it does so, the discharge function of water is further improved.
