An electroacoustic transducer, which can be a speaker or a microphone, includes a frame, a housing, and a vibrating body having one or more vertically split cylindrical faces. The opposing sides of the vibrating body is connected to the housing or the frame. A conversion section converts an electrical signal into vibration of the vibrating body or vibration of the vibrating body to an electrical signal. The vibrating body can extend to the side surfaces of the housing or completely wrap around the housing.
