VIBRATION SENSOR Russian patent published in 2023 - IPC H04R19/04 G01H11/08 

FIELD: measuring technology; vibration sensors.

SUBSTANCE: vibration sensor contains an acoustic transducer; a vibration assembly connected to the acoustic transducer, the vibration assembly being configured to transmit an external vibration signal to the acoustic transducer to generate an electrical signal, the vibration assembly including one or more groups of vibration diaphragms and weight blocks, and the weight blocks being physically connected to the vibration diaphragms. At the same time, the vibration unit is designed so that the degree of sensitivity of the vibration sensor is greater than the degree of sensitivity of the acoustic transducer in one or more target frequency ranges. Each group of the specified one or more groups of vibrating diaphragms and weight blocks corresponds to one of the specified one or more different target frequency ranges, so that the degree of sensitivity of the vibration sensor is greater than the degree of sensitivity of the acoustic transducer in the corresponding target range and the resonant frequencies of at least two groups of said one or more groups of vibrating diaphragms and weight blocks are different.

EFFECT: increase in the degree of sensitivity to vibrations.
