PROBLEM TO BE SOLVED: To provide a drip-proof type sound output device capable of drawing out a lead wire from any of back side and downward of an outer peripheral part.SOLUTION: At the back center of a sound output device, a central concave portion and a groove portion provided for each lead wire so as to reach from the central concave portion to a downward outer peripheral portion, and between the end portion of the outer peripheral portion and the central concave portion, an electric wire open hole for drawing out the lead wire are provided. The lead wire can be drawn out not only to back side but also to downward outer peripheral portion. Water can be discharged from the groove portion so that no water is accumulated at the back side of the sound output device. 【課題】この発明は、背面側又は外周部下方のいずれからもリード線を引き出すことができる防滴型の音響出力装置を提供することを目的とする。【解決手段】音響出力装置背面中央に中央凹部と、該中央凹部から下方の外周部に達するようにリード線毎に設けられる溝部と、該溝部の外周部側端部と前記中央凹部との間に、リード線を引き出す電線貫通孔を設け、リード線を背面へも外周部下方へも引き出せるようにすると共に、音響出力装置背面に水が溜まることが無いように前記溝部から排水できるようにした。【選択図】図３
