Abstract: The present disclosure provides a vibration sensor including a vibration assembly including a mass element and an elastic element, a first acoustic chamber, an acoustic transducer, and a buffer member. In response to an external vibration signal, the vibration assembly vibrates such that a volume of the first acoustic chamber changes. The acoustic transducer is in communication with the first acoustic chamber. In response to a volume change of the first acoustic chamber, the acoustic transducer may generate an electrical signal. The buffer member is connected to the mass element or the elastic element. The buffer member reduces an impact force of the mass element acting on the elastic element during a vibration process of the vibration assembly. The acoustic transducer has a first resonance frequency, the vibration assembly has a second resonance frequency, and the second resonance frequency is less than the first resonance frequency.

The elastic diaphragm may be connected to the housing the sensing device through a peripheral side of the elastic diaphragm. The mass block may be at least made of a polymer material. A first acoustic cavity may be defined between the elastic diaphragm and the sensor. When the housing of the sensing device generates a vibration in response to an external sound signal, the elastic diaphragm and the mass block may generate a vibration in response to the vibration of the housing of the sensing device. The elastic diaphragm may cause a sound pressure change in the first acoustic cavity during a vibration process, and the sensor may convert the external sound signal into an electrical signal based on the sound pressure change in the acoustic cavity. The resonant system may provide at least one second resonant frequency to the sensing device. The second resonant frequency may be lower than the first resonant frequency.
