Title:
WATER-PROOF CASE FOR PORTABLE SMALL-SIZED SOUND PRODUCER
Document Type and Number:
Japanese Patent JP2670662
Kind Code:
B2
Abstract:
PURPOSE: To prevent a water-resistance film capable of ventilation provided to a window of a vinyl bag.
CONSTITUTION: An elliptic porous window zone 6 is formed to one side 2 of a transparent vinyl bag 1 open upward in which a radio receiver is contained. A water resistance film 9 capable of ventilation whose ear 8 is held between spacer rings 8a, 8a is provided to an outer face of the window zone 6 and an elliptic porous film protection cover plate 11 is provided to an outer face of the water resistance film 9. Thus, since the spacer rings 8a, 8a are provided in advance to the ear 8 of the water-resistance film capable of ventilation, it is not damaged at fitting and even when a radio receiver is in use, the receiver is protected by a film protection cover plate 11. Furthermore, since the water resistance film 9 capable of ventilation is vibrated acoustically in a range of the thickness of the spacer rings 8a, 8a, the sound quality of the receiver is not deteriorated.
