Title: Interphone slave set
Inventor: MATSUDA MITSUHIRO
IPC: H04M1/02
Filed: 1988-09-28
Abstract: PURPOSE:To prevent a circuit board and its on board parts from being drenched by providing a drain hole at a place just under a sound hole provided on the upper part of the housing of a doorphone slave unit and at the upper part of the internal circuit board. CONSTITUTION:The drain hole 11 is provided just under the sound hole 6 of a surface panel 2 and at a bending part for an internal side generating a concave part 2a. The drain hole 11 is set almost the same height as the upper edge part of the circuit board 5, and a water avoidance 12 surrounding the upper and the side part of the hole 13 is formed on the surface of the concave part 2a in the surface panel 2. Rainwater immersed into an internal part from the sound hole 6 on the upper part of the surface panel 2 falls down along the inner side of the panel and is discharged to the surface side of the concave part 2a being the outer part of the housing from the drain hole 11 just under the sound hole 6. Water flows down along the outer surface of the concave part 2a avoids the hole 13 since a route is regulated by the water avoidance 12, and therefore water is prevented from immersing into the case from the hole 13 again. Thus, the circuit board is prevented from being drenched by rainwater immersed from the sound hole of the speaker.
