    摘要： Provided is a wireless earphone capable of suppressing an influence on the sound quality of an electroacoustic transducer due to the arrangement of electrical parts such as a battery and a circuit board while reducing the size of a casing. The wireless earphone includes an electroacoustic transducer 14 that outputs a sound wave corresponding to a sound signal from a sound source S, a reception circuit 151 that receives the sound signal from the sound source S via a wireless communication line, a circuit board 15 to which the reception circuit 151 is attached, and a casing 11 that accommodates the circuit board 15 and the electroacoustic transducer 14. The casing 11 includes a first casing 11A that accommodates the electroacoustic transducer 14, and a second casing 11B that accommodates the circuit board 15.

    摘要： The present invention provides a light guide body for a microphone that radiates light from a small number of light sources toward a surrounding of a microphone with a uniform quantity of light. The light guide body for the microphone that guides light from one or more light sources which emit light in accordance with operating a state of a microphone unit of the microphone. The light guide body has a plate shape and comprises one or more incident surfaces on which light from the light source is incident, and one or more grooves, each of which includes a reflecting surface that reflects light incident on the incident surface.
