Abstract

In the vicinity of the outgoing-side end portionof a light guide rod, the rear face thereof is formed into an inclined facebeing inclined in a tapered shape toward the side face. The infrared ray having advanced toward the flat face of the outgoing-side end portionis reflected by the inclined face. The infrared ray reflected by the inclined faceis refracted by the side face of the light guide rodand irradiated, thereby being irradiated while being expanded toward the outgoing-side end portion. Hence, a bar speakercan irradiate the infrared ray in a wide range beyond the width of the housingthereof.
