PURPOSE:To obtain sound quality to be easily listened by constituting this sound collecting microphone of a parabolic shaped sound collecting plate and a microphone supported on the reflection face side of the sound collecting plate through a microphone supporting part and setting up the sound collecting position of the microphone on a prescribed position equal to the focal distance of the sound collecting plate or the inside of the focal distance. CONSTITUTION:The sound collecting microphone 1 consists of a parabolic shaped sound collecting part 2, a parabola supporting part for supporting the part 2 and a microphone supporting part 8 provided with a tripod mounting the microphone 1 on its body part. The sound collecting position of the microphone 1 is a position equal to the focal distance of the sound collecting part 2 or the inside of the position and the microphone (microphone capsule) 1 is arranged so as to be turned to the sound collecting plate side. Thereby a peak signal generated in a high frequency area (especially the vicinity of 10KHz) due to the influence of the supporting part 8 can be canceled and a high frequency component can properly be suppressed. Besides a desirable sound can be generated by adjusting the position of the microphone 1. |
