PROBLEM TO BE SOLVED: To provide a boundary microphone and a desk sound-pressure transducer, having a pressure sensitive switch which is easy to be operated by a user and does not restrict design and the size of its body. SOLUTION: The boundary microphone includes a base 10 formed into a flat shape; a plinth 13 arranged at a bottom of the base; a microphone unit 31 to convert a sound built in the base into an electric signal; and the pressure sensitive switch 12A to turn an output signal of the microphone unit 31 on and off. At least one pressure sensitive switch 12A is arranged so as to be pressed against, between the base 10 and the plinth 13. COPYRIGHT: (C)2011,JPO&INPIT
