構造。[Claims for Utility Model Registration] Consisting of a handset and a main body, the sound generating surface of the sounder for generating sound such as a call bell is opposed to the upper end of a hollow cylindrical rib provided on the bottom surface of the main body. By closely mounting the rib, the inside of the rib becomes a front air chamber for reverberating the sound from the sounder, and a slit part is formed on a part of the circumferential surface of the rib to allow the sound from the front air chamber to flow outside. In a sound-transmitting hole structure for a telephone sounder, the sound-transmitting hole is provided at the base of the slit portion, and a sound-transmitting hole is formed through the bottom side of the main body so as to be continuous with the slit portion, thereby allowing sound to flow out of the main body. A guide portion that stands up in the shape of a wall in contact with the sound transmission hole is provided to face the slit portion of the rib with the sound transmission hole in between, allowing the sound from the slit portion to flow into the interior of the main body and preventing sound transmission. A sound-transmitting hole structure for a telephone sounder, characterized in that the sound is guided into the hole.
