ホン装置。[Scope of claim for utility model registration] (1) A bone conduction type microphone unit that picks up bone conduction sound by directly contacting a vibrating part such as the cheek or throat, and air conduction that picks up sound waves radiated into the air. What is claimed is: 1. A microphone device comprising a type microphone unit, the electrical audio signals of each of the microphone units being synthesized by a mixer and outputted. (2) In claim (1) for utility model registration, the bone conduction type microphone unit has one unit in the main body.
A microphone device characterized in that a low pass filter circuit having a frequency pass band of kHz to 2 kHz or less is connected, and a high pass filter circuit having a frequency pass band higher than that is connected to the air conduction type microphone unit. (3) In claim (1) or (2) for utility model registration, the bone conduction type microphone unit is attached to a case that is worn on the head via a headband, and the air conduction type microphone unit is attached to a case that is attached to the head via a headband. A microphone device characterized in that it is supported by the case via a flexible arm.
