| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide electronic device for preventing the sound emission failure of the diaphragm of a speaker, and for preventing the deterioration of the speaker, by making water hardly stick to the diaphragm of the speaker, even when water infiltrates from a sound hole into a cylindrical part for issuing a sound. SOLUTION: A case 4 is provided with a slit 43B for giving off a sound which is put through the case 4; and a cylindrical part 43C for giving off a sound which is erected toward the inside of the case 4 so that the slit 43B for giving off a sound can be surrounded. The opening of the cylindrical part 43C for giving off a sound is closed by the speaker 3 housed in the case 4. Also, the cylindrical part 43C for giving off a sound is formed with a recessed puddle part 45 on its inner peripheral face toward the perpendicular lower side. COPYRIGHT: (C)2011,JPO&INPIT |
