Summary: | PROBLEM TO BE SOLVED: To enhance articulation of a sound pickup. SOLUTION: A microphone is related to a sound pickup having a sound pressure differential microphone placed in a housing, in order to transduce an acoustic signal generated in an acoustic near field between the housing and the sound pickup into an electrical signal, through the use of a sound pressure difference principle. The sound pressure difference microphone 3 is provided in the housing 4, 5 and a single opening directed on a front face of the microphone 3 is provided in any of housing walls 5, in order to transmit a sound instruction 6 generated in the acoustic near field. The microphone 3 is place, in a way such that the volume of air surrounding the microphone 3 in the housing is formed so that the microphone 3 receives sound radiation through the opening 8 utilizing the principle of the sound pressure difference. |
