Acoustic pressure p=(√ 2* π
2* ρ
o* a
2* f
2* ξ)/r
Wherein: π is a circumference ratio, ρ
oBe atmospheric density, a is the equivalent redius of sound film of loudspeaker piston motion, and f is a vibration frequency, the amplitude that ξ carries out the piston motion for the sound film, and r is the distance of test point and loud speaker.
Therefore, under the identical sound membrane area and under the identical measuring distance, acoustic pressure and frequency square and the first power of amplitude be directly proportional.In order to produce identical acoustic pressure, when high frequency, the sound film needs only minimum amplitude, and is relative, and when low frequency, the sound film is then wanted great amplitude, could produce identical acoustic pressure.Unless the area of sound film is amplified, otherwise the LF-response of ribbon type dynamic planar loudspeakers (Low Frequency Response) is not good.
