¿µ¹®³»¿ë¿ä¾à This standard describes to define evaluation items related to the output frequency response characteristics of the piezoelectric speaker for mobile application and proposes measurement standard of the frequency response characteristics. In this standard, the evaluation items related to the output frequency response characteristics of the piezoelectric speaker for mobile application include driving voltage, average sound pressure level, maximum sound pressure level, frequency response range, deviation of output sound pressure level and frequency response characteristics evaluation by enclosure assembly.
