Abstract

The present disclosure provides a vibration collector. The vibration collector comprises: a vibration collecting component; a first wireless coupler connected to the vibration collecting component; and an attaching component that is made of a flexible material and enables the vibration collector to be fixed onto an outer surface of an object in a detachable manner. When the vibration collector is fixed onto the outer surface of the object, the vibration collecting component collects a vibration from a vibration source and generates an electrical vibration signal based on the vibration. The first wireless coupler transmits the electrical vibration signal to an electronic device for processing. Also provided is an electronic device.
