摘要: Disclosed are a vibration sensor and an electronic equipment. The vibration sensor includes a circuit board assembly, a shell, a vibration pick-up assembly, a support shell and a chip assembly. The shell is configured to cover a side of the circuit board assembly to form an installation space. The vibration pick-up assembly is provided in the installation space, and is configured to pick up an external bone vibration and generate a response vibration. The support shell is connected to a side of the vibration pick-up assembly away from the circuit board assembly. The chip assembly is connected to a side of the support shell away from the circuit board assembly, and is electrically connected to the circuit board assembly. The vibration pick-up assembly, the support shell and the chip assembly are enclosed to form a conduction cavity.
