A method of eliminating vibration interferences of a sphygmomanometer for measuring blood pressure uses a pressure sensor and an acceleration sensor to measure a voltage-time variation waveform of blood pressure detected by an acceleration sensor. An interference variation waveform is subtracted from the measured voltage-time variation waveform to calculate the correct blood pressure value. During measurement, the acceleration sensor detects and determines whether the vibration interference falls within a predetermined allowable range; if yes, a warning signal is issued to remind users to measure blood pressure again; if no, the acceleration sensor detects an interference variation waveform. The inference variation waveform obtained by a conversion function is subtracted from the voltage-time variation waveform when the blood pressure measurement is affected by external vibration interferences, and the original voltage-time variation waveform not affected by vibration interferences is restored, so as to measure a correct blood pressure value.
